Layering Technologies to Support the Enterprise with Semantic Search

Semantic search is a composite beast like many enterprise software applications. Most packages are made up of multiple technology components and often from multiple vendors. This raises some interesting thoughts as we prepare for Gilbane Boston 2009 to be held this week.

As part of a panel on semantic search, moderated by Hadley Reynolds of IDC, with Jeff Fried of Microsoft and Chris Lamb of the OpenCalais Initiative at Thomson Reuters, I wanted to give a high level view of semantic technologies currently in the marketplace. I contacted about a dozen vendors and selected six to highlight for the variety of semantic search offerings and business models.

One case study involves three vendors, each with a piece of the ultimate, customer-facing, product. My research took me to one company that I had reviewed a couple of years ago, and they sent me to their “customer” and to the customer’s customer. It took me a couple of conversations and emails to sort out the connections; in the end the relationships made perfect sense.

On one hand we have conglomerate software companies offering “solutions” to every imaginable enterprise business need. On the other, we see very unique, specialized point solutions to universal business problems with multiple dimensions and twists. Teaming by vendors, each with a solution to one dimension of a need, create compound product offerings that are adding up to a very large semantic search marketplace.

Consider an example of data gathering by a professional services firm. Let’s assume that my company has tens of thousands of documents collected in the course of research for many clients over many years. Researchers may move on to greater responsibility or other firms, leaving content unorganized except around confidential work for individual clients. We now want to exploit this corpus of content to create new products or services for various vertical markets. To understand what we have, we need to mine the content for themes and concepts.

The product of the mining exercise may have multiple uses: help us create a taxonomy of controlled terms, preparing a navigation scheme for a content portal, providing a feed to some business or text analytics tools that will help us create visual objects reflecting various configurations of content. A text mining vendor may be great at the mining aspect while other firms have better tools for analyzing, organizing and re-shaping the output.

Doing business with two or three vendors, experts in their own niches, may help us reach a conclusion about what to do with our information-rich pile of documents much faster. A multi-faceted approach can be a good way to bring a product or service to market more quickly than if we struggle with generic products from just one company.

When partners each have something of value to contribute, together they offer the benefits of the best of all options. This results in a new problem for businesses looking for the best in each area, namely, vendor relationship management. But it also saves organizations from dealing with huge firms offering many acquired products that have to be managed through a single point of contact, a generalist in everything and a specialist in nothing. Either way, you have to manage the players and how the components are going to work for you.

I really like what I see, semantic technology companies partnering with each other to give good-to-great solutions for all kinds of innovative applications. By the way, at the conference I am doing a quick snapshot on each: Cogito, Connotate (with Cormine and WorldTech), Lexalytics, Linguamatics, Sinequa and TEMIS.

Where and How Can You Look for Good Enterprise Search Interface Design?

Designing an enterprise search interface that employees will use on their intranet is challenging in any circumstance. But starting from nothing more than verbal comments or even a written specification is really hard. However, conversations about what is needed and wanted are informative because they can be aggregated to form the basis for the overarching design.

Frequently, enterprise stakeholders will reference a commercial web site they like or even search tools within social sites. These are a great starting point for a designer to explore. It makes a lot of sense to visit scores of sites that are publicly accessible or sites where you have an account and navigate around to see how they handle various design elements.

To start, look at:

  • How easy is it to find a search box?
  • Is there an option to do advanced searches (Boolean or parametric searching)?
  • Is there a navigation option to traverse a taxonomy of terms?
  • Is there a “help” option with relevant examples for doing different kinds of searches?
  • What happens when you search for a word that has several spellings or synonyms, a phrase (with or without quotes), a phrase with the word and in it, a numeral, or a date?
  • How are results displayed: what information is included, what is the order of the results and can you change them? Can you manipulate results or search within the set?
  • Is the interface uncluttered and easily understood?

The point of this list of questions is that you can use it to build a set of criteria for designing what your enterprise will use and adopt, enthusiastically. But this is only a beginning. By actually visiting many sites outside your enterprise, you will find features that you never thought to include or aggravations that you will surely want to avoid. From these experiences on external sites, you can build up a good list of what is important to include or banish from your design.

When you find sites that you think are exemplary, ask key stakeholders to visit them and give you their feedback, preferences and dislikes. Particularly, you want to note what confuses them or enthusiastic comments about what excites them.

This post originated because several press notices in the past month brought to my attention Web applications that have sophisticated and very specialized search applications. I think they can provide terrific ideas for the enterprise search design team and also be used to demonstrate to your internal users just what is possible.

Check out these applications and articles: on KNovel, particularly this KNovel pageThomasNet; EBSCOHost mentioned in this article about the “deep Web.”. All these applications reveal superior search capabilities, have long track records, and are already used by enterprises every day. Because they are already successful in the enterprise, some by subscription, they are worth a second look as examples of how to approach your enterprise’s search interface design.

Competition among Search Vendors

Is there any real competition when it comes to enterprise search? Articles like this one in ComputerWorld make good points but also foster the idea that this could be a differentiator for buyers: Yahoo deal puts IBM, Microsoft in enterprise search pickle, by Juan Carlos Perez, August 4, 2009.

I wrote about the IBM launch of the OmniFind suite of search products a couple of years ago with positive comments. The reality ended up being quite different as I noted later. Among the negatives were three that stand out in my mind. First, free (as in the IBM OmniFind Yahoo no-charge edition) is rarely attractive to serious enterprises looking for a well-supported product. Second, the substantial computing overhead for the free product was significant enough that some SMBs I know of were turned off; the costs associated with the hardware and support it would require offset “free.” Third, my understanding that the search architecture for the free product would provide seamless upgrades to IBM’s other OmniFind products was wrong. Each subsequent product adoption would require the same “rip and replace” that Steve Arnold describes in his report, Beyond Search. It is hard to believe that IBM got much traction out of this offering from the enterprise search market at large. Does anyone know if there was really any head-to-head competition between IBM and other search vendors over this product?

On the other hand, does the Microsoft Express Search offering appeal to enterprises other than the traditional Microsoft shop? If Microsoft Express Search went away, it would probably be replaced by some other Microsoft search variation with inconvenience to the customer who needs to rip and replace and left on his own to grumble and gripe. What else is new? The same thing would happen with IBM Yahoo OmniFind users and they would adapt.

I’ve noticed that free and cheap products may become heavily entrenched in the marketplace but not among organizations likely to upgrade any time soon. Once enterprises get immersed in a complex implementation (and search done well does require that) they won’t budge for a long, long time, even if the solution is less than optimal. By the time they are compelled to upgrade they are usually so wedded to their vendor that they will accept any reasonable offer to upgrade that the vendor offers. Seeking competitive options is really difficult for most enterprises to pursue without an overwhelmingly compelling reason.

This additional news item indicates that Microsoft is still trying to get their search strategy straightened out with another new acquisition, Applied Discovery Selects Microsoft FAST for Advanced E-Discovery Document Search. E-discovery is a hot market in legal, life sciences and financial verticals but firms like ISYS, Recommind, Temis, and ZyLab are already doing well in that arena. It will take a lot of effort to displace those leaders, even if Microsoft is the contender. Enterprises are looking for point solutions to business problems, not just large vendors with a boatload of poorly differentiated products. There is plenty of opportunity for specialized vendors without going toe-to-toe with the big folks.

Convergence of Enterprise Search and Text Analytics is Not New

Prompted by the news item about IBM’s bid for SPSS and similar acquisitions by Oracle, SAP and Microsoft made me think about the predictions of more business intelligence (BI) capabilities being conjoined with enterprise search. But why now and what is new about pairing search and BI? They have always been complementary, not only for numeric applications but also for text analysis. Another article by John Harney in KMWorld referred to the “relatively new technology of text analytics” for analyzing unstructured text. The article is a good summary of some newer tools but the technology itself has had a long shelf life, too long for reasons which I’ll explore later.

Like other topics in this blog this one requires a readjustment in thinking by technology users. One of the great things about digitizing text was the promise of ways in which it could be parsed, sorted and analyzed. With heavy adoption of databases that specialized in textual, as well as numeric and date data fields for business applications in the 1960s and 70s, it became much easier for non-technical workers to look at all kinds of data in new ways. Early database applications leveraged their data stores using command languages; the better ones featured statistical analysis and publication quality report builders. Three that I was familiar with were DRS from ADM, Inc., BASIS from Battelle Columbus Labs and INQUIRE from IBM.

Tools that accompanied database back-ends had the ability to extract, slice and dice the database content, including very large text fields to report: word counts, phrase counts (breaking on any delimiter), transaction counts, relationships among data elements across associated record types, ability to create relationships on the fly, report expert activity and working documents, and describe distribution of resources. These are just a few examples of how new content assets could be created for export in minutes. In particular, a sort command with DRS had histogram controls that were invaluable to my clients managing corporate document and records collections, news clippings files, photographs, patents, etc. They could evaluate their collections by topic, date ranges, distribution, source, and so on, at any time.

So, there existed years ago the ability to connect data structures and use a command language to formulate new data models that informed and elucidated how information was being used in the organization, or to illustrate where there were holes in topics related to business initiatives. What were the barriers to wide-spread adoption? Upon reflection, I came to realize that extracting meaningful content from database in new and innovative formats requires a level of abstract thinking for which most employees are not well-trained. Putting descriptive data into a database via a screen form, then performing a transaction on the object of that data on another form, and then adding more data about another similar but different object are isolated in the database user’s experience and memory. The typical user is not trained to think about how the pieces of data might be connected in the database and therefore is not likely to form new ideas of how it can all be extracted in a report with new information about the content. There is a level of abstraction that eludes most workers whose jobs consist of a lot of compartmentalized tasks.

It was exciting to encounter prospects that really grasped the power of these tools and were excited to push the limits of the command language and reporting applications, but they were scarce. It turned out that our greatest use came in applying text analytics to the extraction of valuable information from our customer support database. A rigorously disciplined staff populated it after every support call with not only demographic information about the nature of the call, linked to a customer record that had been created back at the first contact during the sales process (with appropriate updates along the way in the procurement process) but also a textual description of the entire transaction. Over time this database was linked to a “wish list” database and another “fixes” database and the entire networked structure provided extremely valuable reports that guided both development work and documentation production. We also issued weekly summary reports to the entire staff so everyone was kept informed about product conditions and customer relationships. The reporting tools provided transparency to all staff about company activity and enabled an early version of “social search collaboration.”

Current text analytics products have significantly more algorithmic horsepower than the old command languages. But making the most of their potential and transforming them into utilities that any knowledge worker can leverage will remain a challenge for vendors in the face of poor abstract reasoning among much of the work force. The tools have improved but maybe not in all the ways they need to for widespread adoption. Workers should not have to be dependent on IT folks to create that unique analysis report that reveals a pattern or uncovers product flaws described by multiple customers. We expect workers to multitask, have many aptitudes and skills, and be self-servicing in so many aspects of their work, but for them to flourish the tools fall short too often. I’m putting in a big plug for text analytics for the masses, soon, so that enterprise search begins to deliver more than personalized lists of results for one person at a time. Give more reporting power to the user.

Searching Email in the Enterprise

Last week I wrote about “personalized search” and then a chance encounter at a meeting triggered a new awareness of business behavior that makes my own personalized search a lot different than might work for others. A fellow introduced himself to me as the founder of a start-up with a product for searching email. He explained that countless nuggets of valuable information reside in email and will never be found without a product like the one his company had developed. I asked if it only retrieved emails that were resident in an email application like Outlook; he looked confused and said “yes.” I commented that I leave very little content in my email application but instead save anything with information of value in the appropriate file folders with other documents of different formats on the same topic. If an attachment is substantive, I may create a record with more metadata in my content management database so that I can use the application search engine to find information germane to projects I work on. He walked away with no comment, so I have no idea what he was thinking.

It did start me thinking about the realities of how individuals dispose of, store, categorize and manage their work related documents. My own process goes like this. My work content falls into four broad categories: products and vendors, client organizations and business contacts, topics of interest, and local infrastructure related materials. When material is not purposed for a particular project or client but may be useful for a future activity, it gets a metadata record in the database and is hyperlinked to the full-text. The same goes for useful content out on the Web.

When it comes to email, I discipline myself to dispose of all email into its appropriate folder as soon as I can. Sometimes this involves two emails, the original and my response. When the format is important I save it in the *.mht format (it used to be *.htm until I switched to Office 2007 and realized that doing so created a folder for every file saved); otherwise, I save content in *.txt format. I rename every email to include a meaningful description including topic, sender and date so that I can identify the appropriate email when viewing a folder. If there is an attachment it also gets an appropriate title and date, is stored in its native format and the associated email has “cover” in the file name; this helps associate the email and attachment. The only email that is saved in Outlook in personal folders is current activity where lots of back and forth is likely to occur until a project is concluded. Then it gets disposed of by deleting, or with the project file folders as described above. This is personal governance that takes work. Sometimes I hit a wall and fall behind on the filtering and disposing but I keep at it because it pays off in the long term.

So, why not relax and leave it all in Outlook, then let a search engine do the retrieval? Experience had revealed that most emails are labeled so poorly by senders and the content is so cryptic that to expect a search engine to retrieve it in a particular context or with the correct relevance would be impossible. I know this from the experience of having to preview dozens of emails stored in folders for projects that are active. I have decided to give myself the peace of mind that when the crunch is on, and I really need to go to that vendor file and retrieve what they sent me in March of last year, I can get it quickly in a way that no search engine could ever do. Do you realize how much correspondence you receive from business contacts using their “gmail” account with no contact information revealing their organization in the body and signed with a nickname like “Bob” and messages “like we’re releasing the new version in four weeks” or that just have a link to an important article on the web with “thought this would interest you?”

I did not have a chance to learn if my new business acquaintance had any sense of the amount of competition he has out there for email search, or what his differentiator is that makes a compelling case for a search product that only searches through email, or what happens to his product when Microsoft finally gets FAST search bundled to work with all Office products. OR, perhaps the rest of the world is storing all content in Outlook. Is this true? If so, he may have a winner.

Personalized Search in the Enterprise

This is an interesting topic for two reasons: there is enormous diversity in the ways we all think and go about finding content; personalizing a search interface without being intrusive is extremely difficult. Any technology that requires us to do activities according to someone else’s design, which bends our natural inclination, is by definition not going to be personal.

This topic comes to mind because of two unrelated pieces of content I read in the past 24 hours. The first was an email asking me about personal information management and automated tagging, and the second was an interview I read with Mike Moran, a thought leader in search and speaker at one of our Gilbane Conferences. In the interview, Mike talks about personalized search. Then Information Week referenced search personalization in an article about a patent suit against Google.

Here is my take on the many personalized search themes that have recently emerged. From dashboards to customizing results, options to focus on particular topics or types of content, socialized search to support interacting with and sharing results, to retrieving content we personally created or received (email), content we used or were named in, all might be referred to as search personalization. Getting each to work well will enhance enterprise search but….

Knowing how transient and transformative our thoughts and behaviors really are, we should focus realistically on the complexity of producing software tools and services that satisfy and enhance personal findability. We are ambiguous beings, seeking structured equilibrium in many of our activities to create efficiency and reduce anxiety, while desiring new, better, quicker and smarter devices to excite and engage us. Once we achieve a level of comfort with a method or mechanism, whether quickly or over time, we evolve and seek change. But, when change is imposed on an unprepared mind, our emotions probably override any real benefit that might be gained in productivity. Then we tend to self-sabotage the potential for operational usefulness when an uncomfortable process intrudes. Mental lack of preparedness undermines our work when a new design demands a behavioral shift that lacks connection to our current state or past experiences. How often are we just not in a frame of mind to take on something totally alien, especially with deadlines looming?

Look at the single most successful aspect of Google, minimalism in its interface. One did not need to wade through massively dense graphics scrambled with text in disordered layouts to figure out what to do when Google first appeared. The focus was immediately obvious.

I am presenting this challenge to vendors; there is a need to satisfy a huge array of personal preferences while introducing a minimal amount of change in any one release. Easy adoption requires that new products be simple. Usefulness must be quickly obvious to multiple audiences.

I am presenting this challenge to technology users; focus your appetite. Decide before shopping or adopting new tools what would bring the most immediate productivity gain and personal adoptability for maximum efficiency. Think about how defeated you feel when approaching a new release of an upgraded product that has added so many new “bells and whistles” that you are consumed with trying to rediscover all the old functions and features that gave your workflow a comfortable structure. Think carefully about how much learning and re-adjusting will be needed if you decide on technology that promises to do everything, with unlimited personalization. It may be possible, but does it really feel personally acceptable.

Semantic Search has Its Best Chance for Successes in the Enterprise

I am expecting significant growth in the semantic search market over the next five years with most of it focused on enterprise search. The reasons are pretty straightforward:

  • Semantic search is very hard and to scale it to the Web compounds the complexity.
  • Because the semantic Web is so elusive and results have been spotty with not much traction, it will be some time before it can be easily monetized.
  • Like many things that are highly complex, a good model will be to break the challenge of semantic search into smaller targeted business problems where focus is on a particular audience seeking content from a narrower domain.

I base this predication on my observation of the on-going struggle for organizations to get a strong framework in place to manage content effectively. By effectively I mean, establishing solid metadata, governance and publishing protocols that ensure that the best information knowledge workers produce is placed in range for indexing and retrieval. Sustained discipline and the people to exercise it just aren’t being employed in many enterprises to make this happen in a cohesive and comprehensive fashion. I have been discouraged by the number of well-intentioned projects I have seen flounder because organizations just can’t commit long-term or permanent human resources to the activity of content governance. Sometimes it is just on-again-off-again. What enterprises need are people with deep knowledge about the organization and how its content fits together in a logical framework for all types of knowledge workers. Instead, organizations tend to assign this job to external consultants or low-level staffers who are not well-grounded in the work of the particular enterprise. The results are predictably disappointing.

Enter semantic search technologies where there are multiple algorithmic tools available to index and retrieve content for complex and multi-faceted queries. Specialized semantic technologies are often well suited to shorter term projects for which domain specific vocabularies can be built more quickly with good results. Maintaining targeted vocabulary ontologies for a focused topic can be done with fewer human resources and a carefully bounded ontology can become an intelligent feed to a semantic search engine, helping it index with better precision and relevance.
This scenario is proposed with one caveat; enterprises must commit to having very smart people with enterprise expertise to build the ontology. Having a consultant coach the subject matter expert in method, process and maintenance guidelines for doing so is not a bad idea but the consultant has to prepare the enterprise for sustainability after exiting the scene.

The wager here is that enterprises can ramp up semantic search with a series of short, targeted projects, each of which establishes a goal of solving one business problem at a time and committing to efficient and accurate content retrieval as part of the solution. By learning what works well in each situation, intranet web retrieval will improve systematically and thoughtfully. The ramp to a better semantic Web will be paved with these interlocking pieces.

Keep an eye on these companies to provide technologies for point solutions in business critical applications: Basis Technology, Cognition Technology, Connotate, Expert Systems, Lexalytics, Linguamatics, Metatomix, Semantra, Sinequa and Temis.

It Takes Work to Get Good-to-Great Enterprise Search

It takes patience, knowledge and analysis to tell when search is really working. For the past few years I have seen a trend away from doing any “dog work” to get search solutions tweaked and tuned to ensure compliance with genuine business needs. People get cut, budgets get sliced and projects dumped because (fill the excuse) and the message gets promoted “enterprise search doesn’t work.” Here’s the secret, when enterprise search doesn’t work the chances are it’s because people aren’t working on what needs to be done. Everyone is looking for a quick fix, short cut, “no thinking required” solution.

This plays out in countless variations but the bottom line is that impatience with human processing time and the assumption that a search engine “ought to be able to” solve this problem without human intervention cripple possibilities for success faster than anything else.

It is time for search implementation teams to get realistic about the tasks that must be executed and milestones to be reached. Teams must know how they are going to measure success and reliability, then to stick with it, demanding that everyone agrees on the requirements before throwing the towel in at the first executive anecdote that the “dang thing doesn’t work.”

There are a lot of steps to getting even an out-of-the-box solution working well. But none is more important than paying attention to these:

  • Know your content
  • Know your search audience
  • Know what needs to be found and how it will be looked for
  • Know what is not being found that should be

The operative verb here is to know and to really know anything takes work, brain work, iterative, analytical and thoughtful work. When I see these reactions from IT upon setting off a search query that returns any results: “we’re done” OR “no error messages, good” OR “all these returns satisfy the query,” my reaction is:

  • How do you know the search engine was really looking in all the places it should?
  • What would your search audience be likely to look for and how would they look?
  • Who is checking to make sure these questions are being answered correctly
  • How do you know if the results are complete and comprehensive?

It is the last question that takes digging and perseverance. It is pretty simple to look at search results and see content that should not have been retrieved and figure out why it was. Then you can tune to make sure it does not happen again.

To make sure you didn’t miss something takes systematic “dog work” and you have to know the content. This means starting with a small body of content that it is possible for you to know, thoroughly. Begin with content representative of what your most valued search audience would want to find. Presumably, you have identified these people through establishing a clear business case for enterprise search. (This is not something for the IT department to do but for the business team that is vested in having search work for their goals.) Get these “alpha worker” searchers to show you how they would go about trying to find the stuff they need to get their work done every day, to share with you some of what they consider some of the most valuable documents they have worked with over the past few years. (Yes, years – you need to work with veterans of the organization whose value is well established, as well as with legacy content that is still valuable.)

Confirm that these seminal documents are in the path of the search engine for the index build; see what is retrieved when they are searched for by the seekers. Keep verifying by looking at both content and results to be sure that nothing is coming back that shouldn’t and that nothing is being missed. Then double the content with documents on similar topics that were not given to you by the searchers, even material that they likely would never have seen that might be formatted very differently, written by different authors, and more variable in type and size but still relevant. Re-run the exact searches that were done originally and see what is retrieved. Repeat in scaling increments and validate at every point. When you reach points where content is missing from results that should have been found using the searcher’s method, analyze, adjust, and repeat.

A recent project revealed to me how willing testers are to accept mediocre results when it became apparent how closely content must be scrutinized and peeled back to determine its relevance. They had no time for that and did not care how bad the results were because they had a pre-defined deadline. Adjustments may call for refinements in the query formulation that might require an API to make it more explicit, or the addition of better category metadata with rich cross-references to cover vocabulary variations. Too often this type of implementation discovery signals a reason to shut down the project because all options require human resources and more time. Before you begin, know that this level of scrutiny will be necessary to deliver good-to-great results; set that expectation for your team and management, so it will be acceptable to them when adjustments are needed for more work to be done to get it right. Just don’t blame it on the search engine – get to work, analyze and fix the problem. Only then can you let search loose on your top target audience.

Paying Attention to Enterprise Search Results

When thinking about some enterprise search use cases that require planning and implementation, presentation of search results is not often high on the list of design considerations. Learning about a new layer of software called Documill from CEO and founder, Mika Könnölä, caused me to reflect on possible applications in which his software would be a benefit.

There is one aspect of search output (results) that always makes an impression when I search. Sometimes the display is clear and obvious and other times the first thing that pops into my mind is “what the heck am I looking at” or “why did this stuff appear?” In most cases, no matter how relevant the content may end up being to my query, I usually have to plow through a lot (could be dozens) of content pieces to confirm the validity or usefulness of what is retrieved.

Admittedly, much of my searching is research or helping with a client’s intranet implementation, not just looking for a quick answer, a fact or specific document. When I am in the mode for what I call “quick and dirty” search, I can almost always frame the search statement to get the exact result I want very quickly. But when I am trying to learn about a topic new to me, broaden my understanding or collect an exhaustive corpus of material for research, sifting and validating dozens of documents by opening each and then searching within the text for the piece of the content that satisfied the query is both tedious and annoyingly slow.

That is where Documill could enrich my experience considerably for it can be layered on any number of enterprise search engines to present results in the form of precise thumbnails that show where in a document the query criterion/criteria is located. In their own words, “it enhances traditional search engine result list with graphically accurate presentation of the content.”

Here are some ideas for its application:

  • In an application developed to find specific documents from among thousands that are very similar (e.g. invoices, engineering specifications), wouldn’t it be great to see only a dozen, already opened, pages to the correct location where the data matches the query?
  • In an application of 10s of thousands of legacy documents, OCRed for metadata extraction displayable as PDFs, wouldn’t it be great to have the exact pages of the document that match the search displayed as visual images opened to read in the results page? This is especially important in technical documents of 60-100 pages where the target content might be on page 30 or 50.
  • In federated search output, when results may contain many similar documents, the immediate display of just the right pages as images ready for review will be a time-saving blessing.
  • In a situation where a large corpus of content contains photographs or graphics, such as newspaper archives, scientific and engineering drawings, an instantaneous visual of the content will sharpen access to just the right documents.

I highly recommend that you ask your search engine solution provider about incorporating Documill into your enterprise search architecture. And, if you have, please share your experiences with me through comments to this post or by reaching out for a conversation.
