For a forthcoming BeyeNETWORK article, Perspectives on Text Analytics in 2010, I asked solution-provider executives about the top challenges and opportunities they foresee for the coming year.  Eight out of ten responses cited social media and sentiment analysis: solutions that harvest opinions, attitudes, mood, and other subjective information from news, social media, surveys, and other forms of enterprise feedback.

Claire Thomas, text analytics lead at SAP, calls sentiment analysis "broadly applicable to various industries and initiatives." She captures the rationale for the up-coming Sentiment Analysis Symposium, a conference I am organizing, slated for April 13 in New York. 

Claire and SAP have not endorsed the symposium.  I'm quoting Claire and other industry leaders simply as evidence that a practical, solutions focused sentiment-analysis forum, bridging technology and business concerns, is sorely needed.

Behind the need:

IBM SPSS Vice President Olivier Jouve notes that "Twitter, Facebook and other Web 2.0 media are the new critical sources for marketing" and a range of other enterprise functions.  These functions include what's often now called "social CRM," customer relationship management that taps social sources.  I predict that category will be short-lived, just as early-2000's "e-commerce" is now just one facet of modern, comprehensive business solutions.

The fact is, "more companies are looking at 360-degree views of customer feedback, and social media is a critical early warning (before a customer buys) and customer support (when a customer is having issues) indicator of customer experience," as Clarabridge CEO Sid Banerjee puts it.

I'd guess we can all agree with these statements, but how to handle these and traditional information sources?

According to Lexalytics CEO Jeff Catlin, in 2010, "sentiment will complete its transition to a 'checklist' feature that everyone who works in this space will have to provide.  All of the vendors (big and small) will claim to have sentiment."  So there's a problem evaluating sometimes over-stated claims to choose an appropriate solution.

What's appropriate?  Many user organizations can get by -- for the present -- with what Attensity CTO Ian Hersey characterizes as "social media aggregation and lightweight analytics (e.g., buzz analysis, media monitoring)." 

The Sentiment Analysis Symposium will be for organizations with needs that range from focused to sophisticated, to users who, in Ian's words, want "to incorporate the social media into the same analytical models as they use for their internal data and, more important, plug that social media into business processes."

These enterprise scale users require solutions that, in Olivier Jouve's words, handle sources that are "voluminous, cryptic, multi-lingual and deeply interconnected" via "sophisticated data collection mechanisms, advanced multi-lingual analysis and the infrastructure to manage daily terabytes of data."

This being the BeyeNETWORK's text-analytics channel, I've quoted text-analytics industry leaders although I expect media-monitoring, listening platform, and brand/reputation management users, agencies, and solution providers will be well represented at the Sentiment Analysis Symposium.

So check out the event on-line -- follow @SentimentSymp or me, @SethGrimes, on Twitter for updates -- and you have until February 3 to submit a speaking proposal by the way -- and do send me your questions and comments.

 

I've posted a follow-on to my text-analytics channel article Text Data Quality.  It's titled Text Data Quality: Mistakes and More.  Stay tuned: The BeyeNETWORK will post another article on text data quality, this one focusing on sources, in early December.

Attensity has also released E-Service Version 6.1, an enhanced version of the company's application suite for customer service and support organizations.

Clarabridge launched Clarabridge Social Media Analysis (SMA), which the company characterizes as "the industry's first advanced text analytics software that allows companies to integrate social media content into their existing internal enterprise feedback to create more useful customer analysis," in September. The solution uses social media content from Alterian Techrigy's warehouse of social media content, with data from blogs, Facebook, Twitter, YouTube, MySpace, and other social media sites.

Linguamatics released I2E 3.1 in October. According to the company, key enhancements include support for enterprise deployment, NLP-based querying of a greater choice of document types, a new I2E Chemistry option with substructure and structure similarity search powered by ChemAxon, extended results reporting, flexible hyperlinking from extracted entities to web resources such as gene identifiers, glossaries of biomedical terms, and chemical structure visualization.

Orchestr8, a developer of semantic tagging and text mining software, in September announced a new technology to complement their content analysis service, AlchemyAPI. Visual Constraints is designed for extraction of structured data (product info, pricing, descriptions, etc.) from Web pages. A new, October AlchemyAPI release extends extraction capabilities to quotations and named-entity coreferences.

I recently received an inquiry from a student at a European management school who is writing a thesis about the relationship between search technology and business intelligence. She sees the two technologies as having a meeting point at text analytics and asked to pose a few questions on the topic. Many folks share her interest so my BeyeNETWORK blog seemed like a great place to share my responses. Here goes!

Management student> I have been struggling differentiating some terms and understanding them more clearly. Therefore, my questions are related to that confusion. I would also like to hear your opinion on these two technologies (BI as software and enterprise search) and their uses of text analytics.

MS> What is the difference between text analytics and text mining? Is it related to structured vs. unstructured data? Or is text mining a subset of text analytics?

Seth> There isn't a significant difference. I find that text mining is used in areas that have applied the technology longer and that apply data mining. Examples include life sciences and intelligence (e.g., counter-terrorism). Text analytics is more often used in business.

MS> Is content analysis the same as text analysis (if we look at textual documents, not rich data)?

Seth> To me, "content" generally indicates managed information that is typically found in a repository and that is often published on the Web. In this sense, e-mail and IM messages, survey responses, contact center notes and transcripts, and other forms of text generated during business operations are not content. In this sense, content analysis that concerns text is a subset of text analysis.

But "content" does also cover video, audio, and other media as you note. Content analysis would include these forms where text analysis wouldn't, as you understand, beyond work with textual tags.

MS> Is there a difference between text analytics done by search technology and BI applications?

Seth> Text analytics that backs up search is meant to support information retrieval: indexing, summarizing, and ranking documents in response to a search query. TA enables semantic indexing by topics and themes and relationships in order to go beyond indexing based solely on keywords. TA in support of search can also enable smarter, and natural-language, query processing. The example I'll give is that you can enter "map oslo" in Google and get a map of Oslo, because Google is doing a combination of named entity recognition for the geographic area, Oslo, and pattern matching that understands that "map " is a request for a map.

TA in BI (outside use of search for BI) is different. A complete definition of BI include treatment of information in textual and other forms, in databases, repositories, and on the Web. Search is a BI tool, and so is information extraction (a text analytics technique; information = entities, facts, topics, themes, etc.) into structured databases -- some see IE from text as equivalent to ETL for traditional databases -- and also analysis in the sense of data mining of text-extracted information. So when, for instance, you visualize a relationship network that includes people, companies, etc., based on text-extracted named entities and links (relationships, events, etc.), that's TA at work for BI.

MS > What are the fields that use text analytics the most? (any industries in particular?)

Seth> Life sciences and intelligence (including counter-terrorism) were the earliest use cases with serious work going back to the late '90s and they're still very strong domains for TA. But now we're seeing use in a spectrum of business applications as well.

Seth> Let me refer you for this question and the next to a report I recently published, which you can download for free at http://altaplana.com/TA2009 .

MS> How would you describe text analytics market?

[Seth> In my paper, I estimate a 2008 diversified, global market for text-analytics software and vendor provided professional services at $350 million, representing 40% growth from 2007. I foresee sustained growth rates of up to 25% for 2009.]

MS> There is a lot of talk about eDiscovery where text analytics plays a crucial role, but it is also one of the main markets for search technology. Are these two technologies (is it ok to call text analytics is a technology?) coming together?

Seth> I believe that in e-discovery, the principal application of TA is (still) in support of search in the sense that I wrote about above, creating richer indexes that allow legal researchers (litigants) to respond faster and comprehensively to discovery mandates. TA is only starting to be used by legal professional for investigatory purposes, for what you could call "making the case." Compliance and fraud investigations, and risk management, are starting points in this type of use. But I don't think the technology is being used systematically by litigators yet. I do think we'll see a lot more of this investigatory type of use.

I hope you've found our Q&A useful! As always, if you have questions or comments, do get in touch.

I recently gave a series of talks -- two live presentations and a webinar -- on Text Mining, Web 3.0 & the Semantic Web.  They were sponsored by a software publisher, Nstein, but other than focusing on Nstein's media & publishing sweet spot, my talks were vendor neutral and editorially independent.

I'm thrilled that a couple of attendees have blogged my talk, in particular, my June 18, 2009 London presentation.  John Welsh posted "Seth Grimes on the semantic web - but is B2B media ready to benefit?" and Peter Thomas's write-up was titled "Literary calculus?"  (I don't know why these two Brits are so enamored of question marks.) 

As an aside -- Peter had earlier posted a blog article, "A first for me...," noting that he "received my invitation to the event through Seth himself after having made contact with him on twitter.com."  I'm the first person Peter has met "IRL" -- you can surely guess what those letters stand for -- post our twitter contact.  I similarly met analyst Merv Adrian that way.  We became twitter friends through mutual real-life contacts.  Then one May morning he tweeted that he was in New York City for a meeting, near Penn Station.  It so happens that I was in New York to attend a different meeting, and I was staying near Penn Station.  Forty-five minutes later, Merv and I were sitting down to breakfast.  (For you foodies: We met at the Tick-Tock Diner at the corner of 34th St. and 8th Ave and both had the excellent corned-beef hash.)

It's software that can analyze and transform "data in flight" without requiring data to be loaded to a data warehouse.  So CI takes BI beyond real time to deliver intelligence on demand.  I'm working with a sponsoring company, Aleri, to understand the needs of data users.  You can respond anonymously.  We will send the first 200 respondents a $5 Amazon gift card in thanks!

I'll quickly hit several text-analytics topics in this blog article: a Summit, a Survey, Interest Indicators, and Market Growth.

Market Growth Keeps Pace

In my article, Market Outlook for Text Analytics, I foresaw sustained text-analytics market growth of 25% in 2009. I'm pleased that earnings announcements made since the date I submitted my article, April 6, affirm that prediction. Notably, text-analytics giant (albeit under the guise of an enterprise search platform and applications vendor) Autonomy announced "record revenues, up 23% from Q1 2008 including strong organic growth." (Revenue due to Autonomy's Interwoven acquisition, which closed March 17, would have had only a relatively minor role in this growth.) And TEMIS 2009 Q1 "revenue reflects an overall growth of over 30% compared to last year." This is great news despite a global economic downturn!

Text Analytics Survey

It's important also to look at the demand side, at customer and prospect perspectives.

Please respond to a survey I'm conducting. I'd like to know how your organization is dealing with "unstructured" information and the role text mining/analytics plays or might play. I'll write up survey findings in a free report, available in early June. The survey will take you 5-10 minutes. Please help.

Text Analytics Summit

Next, I want to make sure you're aware of this year's Text Analytics Summit, slated for June 1-2 in Boston. You can get $100 off your registration with the link I've provided if you enter my name in the promotional offer box. (Note that I do not have a financial interest in registrations or the summit.) Also, this year I'll again be leading a workshop, "Text Analytics for Dummies," the afternoon of May 31.

Interest Indicators

Interest in text analysis is growing! I've been interviewed recently by several outlets as a leading consultant and analyst:

• By data-mining newsletter KDnuggets.
• In a podcast, part of Jon Udell's Interviews with Innovators series.
