Enterprise search down – 10 years of effort for what? – Need Text Analytics to work Text Analytics is slowly growing – time for a jump? 4 Text Analytics Workshop Current State of Text Analytics Current Market: 2012 – exceed $1 Bil for text analytics (10% of total Analytics) Growing 20% a year Search is 33% of total market Other major areas: – Sentiment and Social Media Analysis, Customer Intelligence – Business Intelligence, Range of text based applications Fragmented market place – full platform, low level, specialty – Embedded in content management, search, No clear leader. Big Data – Big Text is bigger, text into data, data for text – Watson – ensemble methods, pun module 5 Text Analytics Workshop Current State of Text Analytics: Vendor Space Taxonomy Management – SchemaLogic, Pool Party From Taxonomy to Text Analytics – Data Harmony, Multi-Tes Extraction and Analytics – Linguamatics (Pharma), Temis, whole range of companies Business Intelligence – Clear Forest, Inxight Sentiment Analysis – Attensity, Lexalytics, Clarabridge Open Source – GATE Stand alone text analytics platforms – IBM, SAS, SAP, Smart Logic, Expert System, Basis, Open Text, Megaputer, Temis, Concept Searching Embedded in Content Management, Search – Autonomy, FAST, Endeca, Exalead, etc. 6 Future Directions: Survey Results Important Areas: – Predictive Analytics & text mining – 90% – Search & Search-based Apps – 86% – Business Intelligence – 84% – Voice of the Customer – 82%, Social Media – 75% – Decision Support, KM – 81% – Big Data- other – 70%, Finance – 61% – Call Center, Tech Support – 63% – Risk, Compliance, Governance – 61% – Security, Fraud Detection-54% 7 Future Directions: Survey Results 28% just getting started, 11% not yet What factors are holding back adoption of TA? Lack of clarity about value of TA – 23.4% – Lack of knowledge about TA – 17.0% – Lack of senior management buy-in - 8.5% – Don’t believe TA has enough business value -6.4% – Other factors Financial Constraints – 14.9% – Other priorities more important – 12.8% – Lack of articulated strategic vision – by vendors, consultants, advocates, etc. 8 Introduction: Future Directions What is Text Analytics Good For? 9 Text Analytics Workshop What is Text Analytics? Text Mining – NLP, statistical, predictive, machine learning Semantic Technology – ontology, fact extraction Extraction – entities – known and unknown, concepts, events – Catalogs with variants, rule based Sentiment Analysis – Objects/ Products and phrases – Statistics, catalogs, rules – Positive and Negative Auto-categorization – – – – – Training sets, Terms, Semantic Networks Rules: Boolean - AND, OR, NOT Advanced – DIST(#), ORDDIST#, PARAGRAPH, SENTENCE Disambiguation - Identification of objects, events, context Build rules based, not simply Bag of Individual Words 10 11 Case Study – Categorization & Sentiment 12 Case Study – Categorization & Sentiment 13 14 15 16 17 18 19 Case Study – Taxonomy Development 20 Text Analytics Workshop: Information Environment Building an Infrastructure Semantic Layer = Taxonomies, Metadata, Vocabularies + Text Analytics – adding cognitive science, structure to unstructured Modeling users/audiences Technology Layer – Search, Content Management, SharePoint, Intranets Publishing process, multiple users & info needs – SharePoint – taxonomies but • Folksonomies – still a bad idea Infrastructure – Not an Application – Business / Library / KM / EA – not IT Building on the Foundation – Info Apps (Search-based Applications) Foundation of foundation – Text Analytics 21 Text Analytics Workshop: Information Environment TA & Taxonomy Complimentary Information Platform Taxonomy provides a consistent and common vocabulary – Enterprise resource – integrated not centralized Text Analytics provides a consistent tagging – Human indexing is subject to inter and intra individual variation Taxonomy provides the basic structure for categorization – And candidates terms Text Analytics provides the power to apply the taxonomy – And metadata of all kinds Text Analytics and Taxonomy Together – Platform – Consistent in every dimension – Powerful and economic 22 Text Analytics Workshop: Information Environment Metadata - Tagging How do you bridge the gap – taxonomy to documents? Tagging documents with taxonomy nodes is tough – And expensive – central or distributed Library staff –experts in categorization not subject matter – Too limited, narrow bottleneck – Often don’t understand business processes and business uses Authors – Experts in the subject matter, terrible at categorization – Intra and Inter inconsistency, “intertwingleness” – Choosing tags from taxonomy – complex task – Folksonomy – almost as complex, wildly inconsistent – Resistance – not their job, cognitively difficult = non-compliance Text Analytics is the answer(s)! 23 Text Analytics Workshop: Information Environment Mind the Gap – Manual-Automatic-Hybrid All require human effort – issue of where and how effective Manual - human effort is tagging (difficult, inconsistent) – Small, high value document collections, trained taggers Automatic - human effort is prior to tagging – auto-categorization rules and/or NLP algorithm effort Hybrid Model – before (like automatic) and after – Build on expertise – librarians on categorization, SME’s on subject terms Facets – Requires a lot of Metadata - Entity Extraction feeds facets – more automatic, feedback by design Manual - Hybrid – Automatic is a spectrum – depends on context 24 Text Analytics Workshop Benefits of Text Analytics Why Text Analytics? – Enterprise search has failed to live up to its potential – Enterprise Content management has failed to live up to its potential – Taxonomy has failed to live up to its potential – Adding metadata, especially keywords has not worked What is missing? Intelligence – human level categorization, conceptualization – Infrastructure – Integrated solutions not technology, software – Text Analytics can be the foundation that (finally) drives success – search, content management, and much more 25 Text Analytics Workshop Costs and Benefits IDC study – quantify cost of bad search Three areas: – Time spent searching – Recreation of documents – Bad decisions / poor quality work Costs – 50% search time is bad search = $2,500 year per person – Recreation of documents = $5,000 year per person – Bad quality (harder) = $15,000 year per person Per 1,000 people = $ 22.5 million a year – 30% improvement = $6.75 million a year – Add own stories – especially cost of bad information – Human measure - # of FTE’s, savings passed on to customers, etc. 26 Text Analytics Workshop Need for a Quick Start Text Analytics is weird, a bit academic, and not very practical • It involves language and thinking and really messy stuff On the other hand, it is really difficult to do right (Rocket Science) Organizations don’t know what text analytics is and what it is for TAW Survey shows - need two things: • Strategic vision of text analytics in the enterprise • Business value, problems solved, information overload • Text Analytics as platform for information access • Real life functioning program showing value and demonstrating an understanding of what it is and does Quick Start – Strategic Vision – Software Evaluation – POC / Pilot 27 Text Analytics Workshop Text Analytics Vision & Strategy Strategic Questions – why, what value from the text analytics, how are you going to use it – Platform or Applications? What are the basic capabilities of Text Analytics? What can Text Analytics do for Search? – After 10 years of failure – get search to work? What can you do with smart search based applications? – RM, PII, Social ROI for effective search – difficulty of believing – Problems with metadata, taxonomy 28 Text Analytics Workshop Quick Start Step One- Knowledge Audit Ideas – Content and Content Structure Map of Content – Tribal language silos – Structure – articulate and integrate – Taxonomic resources – People – Producers & Consumers – Communities, Users, Central Team Activities – Business processes and procedures – Semantics, information needs and behaviors – Information Governance Policy Technology – – CMS, Search, portals, text analytics Applications – BI, CI, Semantic Web, Text Mining 29 Text Analytics Workshop Quick Start Step One- Knowledge Audit Info Problems – what, how severe Formal Process – Knowledge Audit – Contextual & Information interviews, content analysis, surveys, focus groups, ethnographic studies, Text Mining Informal for smaller organizations, specific application Category modeling – Cognitive Science – how people think – Panda, Monkey, Banana Natural level categories mapped to communities, activities • Novice prefer higher levels • Balance of informative and distinctiveness Strategic Vision – Text Analytics and Information/Knowledge Environment 30 Quick Start Step Two - Software Evaluation Varieties of Taxonomy/ Text Analytics Software Software is more important to text analytics – No spreadsheets for semantics Taxonomy Management - extraction Full Platform – SAS, SAP, Smart Logic, Concept Searching, Expert System, IBM, Linguamatics, GATE Embedded – Search or Content Management – FAST, Autonomy, Endeca, Vivisimo, NLP, etc. – Interwoven, Documentum, etc. Specialty / Ontology (other semantic) Sentiment Analysis – Attensity, Lexalytics, Clarabridge, Lots – Ontology – extraction, plus ontology – 31 Quick Start Step Two - Software Evaluation Different Kind of software evaluation Traditional Software Evaluation - Start Filter One- Ask Experts - reputation, research – Gartner, etc. • Market strength of vendor, platforms, etc. • Feature scorecard – minimum, must have, filter to top 6 – Filter Two – Technology Filter – match to your overall scope and capabilities – Filter not a focus – Filter Three – In-Depth Demo – 3-6 vendors – Reduce to 1-3 vendors Vendors have different strengths in multiple environments – – Millions of short, badly typed documents, Build application Library 200 page PDF, enterprise & public search 32 Quick Start Step Two - Software Evaluation Design of the Text Analytics Selection Team IT - Experience with software purchases, needs assess, budget – Search/Categorization is unlike other software, deeper look Business -understand business, focus on business value They can get executive sponsorship, support, and budget – But don’t understand information behavior, semantic focus Library, KM - Understand information structure Experts in search experience and categorization – But don’t understand business or technology Interdisciplinary Team, headed by Information Professionals Much more likely to make a good decision Create the foundation for implementation 33 Quick Start Step Three – Proof of Concept / Pilot Project POC use cases – basic features needed for initial projects Design - Real life scenarios, categorization with your content Preparation: – Preliminary analysis of content and users information needs • Training & test sets of content, search terms & scenarios – Train taxonomist(s) on software(s) – Develop taxonomy if none available Four week POC – 2 rounds of develop, test, refine / Not OOB Need SME’s as test evaluators – also to do an initial categorization of content Majority of time is on auto-categorization 34 Text Analytics Workshop POC Design: Evaluation Criteria & Issues Basic Test Design – categorize test set – Score – by file name, human testers Categorization & Sentiment – Accuracy 80-90% – Effort Level per accuracy level Combination of scores and report Operators (DIST, etc.) , relevancy scores, markup Development Environment – Usability, Integration Issues: – Quality of content & initial human categorization – Normalize among different test evaluators – Quality of taxonomy – structure, overlapping categories 35 Quick Start for Text Analytics Proof of Concept -- Value of POC Selection of best product(s) Identification and development of infrastructure elements – taxonomies, metadata – standards and publishing process Training by doing –SME’s learning categorization, Library/taxonomist learning business language Understand effort level for categorization, application Test suitability of existing taxonomies for range of applications Explore application issues – example – how accurate does categorization need to be for that application – 80-90% Develop resources – categorization taxonomies, entity extraction catalogs/rules 36 Text Analytics Workshop POC and Early Development: Risks and Issues CTO Problem –This is not a regular software process Semantics is messy not just complex – 30% accuracy isn’t 30% done – could be 90% Variability of human categorization Categorization is iterative, not “the program works” – Need realistic budget and flexible project plan Anyone can do categorization – Librarians often overdo, SME’s often get lost (keywords) Meta-language issues – understanding the results – Need to educate IT and business in their language 37 Development 38 Text Analytics Development: Categorization Process Start with Taxonomy and Content Starter Taxonomy – If no taxonomy, develop (steal) initial high level • Textbooks, glossaries, Intranet structure • Organization Structure – facets, not taxonomy Analysis of taxonomy – suitable for categorization – – Structure – not too flat, not too large Orthogonal categories Content Selection – – – Map of all anticipated content Selection of training sets – if possible Automated selection of training sets – taxonomy nodes as first categorization rules – apply and get content 39 Text Analytics Workshop Text Analytics Development: Categorization Process First Round of Categorization Rules Term building – from content – basic set of terms that appear often / important to content Add terms to rule, apply to broader set of content Repeat for more terms – get recall-precision “scores” Repeat, refine, repeat, refine, repeat Get SME feedback – formal process – scoring Get SME feedback – human judgments Test against more, new content Repeat until “done” – 90%? 40 Text Analytics Workshop Text Analytics Development: Entity Extraction Process Facet Design – from Knowledge Audit, K Map Find and Convert catalogs: – – – – Organization – internal resources People – corporate yellow pages, HR Include variants Scripts to convert catalogs – programming resource Build initial rules – follow categorization process – – – Differences – scale, threshold – application dependent Recall – Precision – balance set by application Issue – disambiguation – Ford company, person, car 41 Text Analytics Workshop Text Analytics Development: Demo BioPharma – scientific vocabulary / articles 42 Text Analytics Workshop Case Study - Background Inxight Smart Discovery Multiple Taxonomies – – Healthcare – first target Travel, Media, Education, Business, Consumer Goods, Content – 800+ Internet news sources – 5,000 stories a day Application – Newsletters – – Editors using categorized results Easier than full automation 43 Text Analytics Workshop Case Study - Approach Initial High Level Taxonomy Auto generation – very strange – not usable – Editors High Level – sections of newsletters – Editors & Taxonomy Pro’s - Broad categories & refine – Develop Categorization Rules – Multiple Test collections – Good stories, bad stories – close misses - terms Recall and Precision Cycles – – Refine and test – taxonomists – many rounds Review – editors – 2-3 rounds Repeat – about 4 weeks 44 45 46 47 Text Analytics Workshop Case Study – Issues & Lessons Taxonomy Structure: Aggregate vs. independent nodes – Children Nodes – subset – rare Trade-off of depth of taxonomy and complexity of rules No best answer – taxonomy structure, format of rules – Need custom development – Recall more important than precision – editors role Combination of SME and Taxonomy pros – Combination of Features – Entity extraction, terms, Boolean, filters, facts Training sets and find similar are weakest Plan for ongoing refinement 48 Text Analytics Workshop Enterprise Environment – Case Studies A Tale of Two Taxonomies – It was the best of times, it was the worst of times Basic Approach – – – – – – Initial meetings – project planning High level K map – content, people, technology Contextual and Information Interviews Content Analysis Draft Taxonomy – validation interviews, refine Integration and Governance Plans 49 Text Analytics Workshop Enterprise Environment – Case One – Taxonomy, 7 facets Taxonomy of Subjects / Disciplines: – Science > Marine Science > Marine microbiology > Marine toxins Facets: – Organization > Division > Group – Clients > Federal > EPA – Facilities > Division > Location > Building X – Content Type – Knowledge Asset > Proposals – Instruments > Environmental Testing > Ocean Analysis > Vehicle – Methods > Social > Population Study – Materials > Compounds > Chemicals 50 Text Analytics Workshop Enterprise Environment – Case One – Taxonomy, 7 facets Project Owner – KM department – included RM, business process Involvement of library - critical Realistic budget, flexible project plan Successful interviews – build on context – Overall information strategy – where taxonomy fits Good Draft taxonomy and extended refinement – – Software, process, team – train library staff Good selection and number of facets Developed broad categorization and one deep-Chemistry Final plans and hand off to client 51 Text Analytics Workshop Enterprise Environment – Case Two – Taxonomy, 4 facets Taxonomy of Subjects / Disciplines: – Geology > Petrology Facets: – Organization > Division > Group – Process > Drill a Well > File Test Plan – Assets > Platforms > Platform A – Content Type > Communication > Presentations 52 Enterprise Environment – Case Two – Taxonomy, 4 facets Environment & Project Issues Value of taxonomy understood, but not the complexity and scope – Under budget, under staffed Location – not KM – tied to RM and software – Solution looking for the right problem Importance of an internal library staff – Difficulty of merging internal expertise and taxonomy Project mind set – not infrastructure – Rushing to meet deadlines doesn’t work with semantics Importance of integration – with team, company – Project plan more important than results 53 Enterprise Environment – Case Two – Taxonomy, 4 facets Research and Design Issues Research Issues – Not enough research – and wrong people – Misunderstanding of research – wanted tinker toy connections • Interview 1 leads to taxonomy node 2 Design Issues – Not enough facets – Wrong set of facets – business not information – Ill-defined facets – too complex internal structure 54 Enterprise Environment – Case Two – Taxonomy, 4 facets Conclusion: Risk Factors Political-Cultural-Semantic Environment – Not simple resistance - more subtle • – re-interpretation of specific conclusions and sequence of conclusions / Relative importance of specific recommendations Access to content and people – Enthusiastic access Importance of a unified project team – Working communication as well as weekly meetings 55 Applications 56 Text Analytics Workshop Building on the Foundation Text Analytics: Create the Platform – CM & Search – New Electronic Publishing Process • Use text analytics to tag, new hybrid workflow – New Enterprise Search • Build faceted navigation on metadata, extraction Enhance Information Access in the Enterprise - InfoApps – Governance, Records Management, Doc duplication, Compliance – Applications – Business Intelligence, CI, Behavior Prediction eDiscovery, litigation support, Fraud detection Productivity / Portals – spider and categorize, extract – – 57 Text Analytics Workshop Information Platform: Content Management Hybrid Model – Internal Content Management – Publish Document -> Text Analytics analysis -> suggestions for categorization, entities, metadata - > present to author – Cognitive task is simple -> react to a suggestion instead of select from head or a complex taxonomy – Feedback – if author overrides -> suggestion for new category External Information - human effort is prior to tagging – More automated, human input as specialized process – periodic evaluations – Precision usually more important – Target usually more general 58 Text Analytics and Search Multi-dimensional and Smart Faceted Navigation has become the basic/ norm – Facets require huge amounts of metadata – Entity / noun phrase extraction is fundamental – Automated with disambiguation (through categorization) Taxonomy – two roles – subject/topics and facet structure – Complex facets and faceted taxonomies Clusters and Tag Clouds – discovery & exploration Auto-categorization – aboutness, subject facets – This is still fundamental to search experience – InfoApps only as good as fundamentals of search People – tagging, evaluating tags, fine tune rules and taxonomy 59 60 61 Integrated Facet Application Design Issues - General What is the right combination of elements? – Dominant dimension or equal facets – Browse topics and filter by facet, search box – How many facets do you need? Scale requires more automated solutions – More sophisticated rules Issue of disambiguation: Same person, different name – Henry Ford, Mr. Ford, Henry X. Ford – Same word, different entity – Ford and Ford – Number of entities and thresholds per results set / document – Usability, audience needs Relevance Ranking – number of entities, rank of facets 62 Text Analytics Workshop : Applications Text and Data: Two Way Street New types of applications – New ways to make sense of data, enrich data Harvard – Analyzing Text as Data – Detecting deception, Frame Analysis Narrative Science – take data (baseball statistics, financial data) and turn into a story Political campaigns using Big Data, social media, and text analytics Watson for healthcare – help doctors keep up with massive information overload 63 Text Analytics Workshop : Applications Social Media: Beyond Simple Sentiment Beyond Good and Evil (positive and negative) – Social Media is approaching next stage (growing up) – Where is the value? How get better results? Importance of Context – around positive and negative words Rhetorical reversals – “I was expecting to love it” – Issues of sarcasm, (“Really Great Product”), slanguage – Granularity of Application Early Categorization – Politics or Sports Limited value of Positive and Negative – Degrees of intensity, complexity of emotions and documents Addition of focus on behaviors – why someone calls a support center – and likely outcomes – 64 Text Analytics Workshop : Applications Social Media: Beyond Simple Sentiment Two basic approaches [Limited accuracy, depth] – Statistical Signature of Bag of Words – Dictionary of positive & negative words Essential – need full categorization and concept extraction New Taxonomies – Appraisal Groups – Adjective and modifiers – “not very good” – Supports more subtle distinctions than positive or negative Emotion taxonomies - Joy, Sadness, Fear, Anger, Surprise, Disgust – New Complex – pride, shame, confusion, skepticism 65 Text Analytics Workshop: Applications Expertise Analysis Expertise Analysis – Experts think & write differently – process, chunks Expertise Characterization for individuals, communities, documents, and sets of documents Applications: – Business & Customer intelligence, Voice of the Customer – Deeper understanding of communities, customers – better models – Security, threat detection – behavior prediction, Are they experts? – Expertise location- Generate automatic expertise characterization Crowd Sourcing – technical support to Wiki’s Political – conservative and liberal minds/texts – Disgust, shame, cooperation, openness 66 Text Analytics Workshop: Applications Behavior Prediction – Telecom Customer Service Problem – distinguish customers likely to cancel from mere threats Basic Rule – (START_20, (AND, (DIST_7,"[cancel]", "[cancel-what-cust]"), – (NOT,(DIST_10, "[cancel]", (OR, "[one-line]", "[restore]", “[if]”))))) Examples: – customer called to say he will cancell his account if the does not stop receiving a call from the ad agency. – cci and is upset that he has the asl charge and wants it off or her is going to cancel his act More sophisticated analysis of text and context in text Combine text analytics with Predictive Analytics and traditional behavior monitoring for new applications 67 Text Analytics Workshop: Applications Variety of New Applications Essay Evaluation Software - Apply to expertise characterization – Avoid gaming the system – multi-syllabic nonsense • Model levels of chunking, procedure words over content Legal Review Significant trend – computer-assisted review (manual =too many) – TA- categorize and filter to smaller, more relevant set – Payoff is big – One firm with 1.6 M docs – saved $2M – Financial Services – – – – Trend – using text analytics with predictive analytics – risk and fraud Combine unstructured text (why) and structured transaction data (what) Customer Relationship Management, Fraud Detection Stock Market Prediction – Twitter, impact articles 68 Text Analytics Workshop: Applications Pronoun Analysis: Fraud Detection; Enron Emails Patterns of “Function” words reveal wide range of insights Function words = pronouns, articles, prepositions, conjunctions, etc. – Used at a high rate, short and hard to detect, very social, processed in the brain differently than content words Areas: sex, age, power-status, personality – individuals and groups Lying / Fraud detection: Documents with lies have – Fewer and shorter words, fewer conjunctions, more positive emotion words – More use of “if, any, those, he, she, they, you”, less “I” – More social and causal words, more discrepancy words Current research – 76% accuracy in some contexts Text Analytics can improve accuracy and utilize new sources Data analytics (standard AML) can improve accuracy 69 Text Analytics Workshop Conclusions Text Analytics and Taxonomy are partners – enrich each other Text Analytics can mind the gap – between taxonomies and documents Text Analytics needs strategic vision and quick start – Need to approach as platform – deep context – understand information environment Text Analytics is a platform for huge range of applications: – – Search and Content Management and Basic productivity apps New kinds of applications - social, data, Info Apps of all kinds Want to learn more – come to Text Analytics World in Boston in Fall! – Early Bird Registration – www.textanalyticsworld.com 70 Questions?
