Advances in text analysis

Meaning-Based Computing: Text Analysis Takes a Great Leap Forward by Terence K. Huwe, Information Today (Sept / OCt 2011)

Meaning-based computing (MBC) is finally getting its due.

"MBC unites the power of modern search protocols with recent advances in text pattern recognition, language-context analysis, and even “sentiment analysis”— which sounds somewhat mysterious. The cumulative advances in MBC are enabling computers to make far more useful inferences about the meaning of communications, even as language usage evolves. Although MBC has been used over the past 8 years with considerable success, the synergy of recent advances has gained wider attention. "

MBC will aid, not supplant, the creation and use of taxonomies for access.

"Taxonomy: It will still matter. The contemporary web is a matrix of artifacts and living documents that have their own “social life,” as Xerox Palo Alto Research Center’s John Seely Brown famously said in the book, The Social Life of Information, which he co-authored with Paul Duguid. HTML5 and the semantic web will add embedded functionalities that further support the development of taxonomies, ontologies, and crowdsourcing techniques to tag useful resources. Meaning-based computing will not supplant these features, although it will likely introduce powerful new ways to look inside document wrappers and parse the evolving meaning of everyday language. If so, then MBC presents digital content managers with another new opportunity to improve access and retrieval. "

Browsable facets

Categories, Facets—and Browsable Facets? by Jaimie Sirovich, UX Matters (Aug 23)

For people designing taxonomies for e-commerce sites, this article could be the ticket. It's about creating a browsable facet - a situation where facets (attributes) can intersect with a taxonomy of categories. Product search can have this problem - where the structure is based on brand (Sony, Panasonic etc) and it is difficult to filter by facet.

The Synaptica Taxonomy Warehouse

Synaptica has re-vamped its informational website at www.taxonomywarehouse.com. "Taxonomy Warehouse is a free online resource that has answered millions of enquiries about taxonomies".

From the e-newsletter:

"This year we imported all of the content from the old Taxonomy Warehouse website into a Synaptica system and re-engineered the directory to become a semantically rich ontology. When you visit Taxonomy Warehouse, all the content and functionality you will see is dynamically generated from Synaptica. Besides providing the taxonomy community with lots of valuable content, we hope that the all-new Taxonomy Warehouse will provide a showcase for building and publishing ontologies. We invite you to follow us on Facebook and Twitter to keep informed as we roll out additional content and features."

The Taxonomy Watch Blog is pleased and honoured to be listed in this database.

Online Course - Ontologies

Enterprise Search - vendors and trends

Stephen E Arnold often writes about search companies and is an expert on the industry. Pandia has summarized a few main points from his most recent e-book, Landscape of Enterprise Search.

Enterprise Search, Trends and Solutions

Note the new intelligence that is embedded in the new search products:
http://www2.blogger.com/img/blank.gif
"Search vendors and niche software specialists offer components than can assign index terms not contained in a source document.

The advantage of systems that assign metatags via “smart software” or via a combination of automatic systems and human subject matter experts is sometimes called “discovery”. The idea is that the interface displays related information or suggests documents that may help the user answer a question. "

Leading companies in this field are Autonomy, Endeca, Vivisimo, Exalead, Google and Microsoft.

The book is available for download for only $20 - sounds like a bargain to me -- http://www.pandia.com/enterprise-search/

Ontologies needed for healthcare

Why Do We Need Ontologies in Healthcare Applicatihttp://www2.blogger.com/img/blank.gifons by Joel Amoussou,Adventures in Computing. (Aug 27)

Some effort here to define ontologies vs data structures.

"Ontologies are our conceptualization (understanding) of the world while information models (of data structures) describe and constrain how the data is stored and transmitted in messages."

He presents a strong argument on why ontologies - a semantic frame of reference - is so direly needed in healthcare.

"For obvious reasons, healthcare applications require a high degree of model quality and consistency. This is not always possible or easy to do with traditional approaches such as object-oriented design (the HL7 RIM is based on the UML) and data structures such as XML and relational database schemas.

A clear and clean separation of concerns is needed between the semantic model (the ontology) and the information model (the model of how the data is structured in an XML message or the health application's data store). The ontology can be used to verify that the content of a message is accurate in regard to our conceptualization of the world, while the information model is used to validate the data structure in the data stores and XML messages exchanged with other applications.

Content Choreography Seminar Series

Fascinating new 4-part webinar series coming up at Earley and Associates - Content in Context: Why Dynamic Content and Content Choreography Is Critical to Information Management

"Dynamic content management combines sophisticated use of taxonomy and content metadata to choreograph and assemble information based on various factors – who the user is, what step in a process they are engaged in, what information they need to execute a task, the topics they are interested in, etc."

The Earley newsletter described content choreography very cleverly -- "Taxonomy and metadata have the potential to be so much more than just strings on a content puppet (although they certainly act that way at a minimum). That's where the choreography part comes in - planning, composing, organizing, presenting, reacting to audience interaction in a controlled yet artful way. It's like the difference between your last high school dance and the Cirque du Soleil."

There is an accompanying slideshow presentation with definitions, process for building, and application.

HP acquires Autonomy

HP to Acquire Info Management Software Firm Autonomy, Joab Jackson, IDG news via PCWorld (Aug 18)

Hewlett-Packard is changing its strips from hardware to software - it is acquiring information management software vendor Autonomyfor $10.3 billion. It wants into enterprise software - and Autonomy has that in spades.

"Founded in 1996, Autonomy offers a broad line of information management software, including enterprise search, content management, data analysis and governance software. It serves more than 25,000 organizations, including BAE Systems, Boeing, Citigroup, Coca Cola, FedEx, Ford, the New York Stock Exchange, Shell, Tesco, T-Mobile, the U.S. Department of Homeland Security and the U.S. Securities and Exchange Commission. Software companies such as Citrix, Oracle, Sybase, Symantec, Tibco as well as HP itself all incorporate Autonomy software into their own packaged offerings."

Eqentia using semantic technologies

Eqentia Offers More Robust Taxonomy Capabilities For Content Curators, And More, Jennifer Zaino, Semantic Web (Aug 3)
the
A lot is happening in use of taxonomies at Eqentia, a custom-news centre, to help users find more on topics of interest.

"Eqentia added to its content discovery and knowledge management portal this week features to recommend additional content or people connections to end users and content curators. But it’s also been doing some other interesting work in the past couple of months on the back-end that draws on semantic technologies to help curators and content administrators of custom Eqentia-based knowledge portals with their taxonomies."

Google+ entities and attributes

Thoughts on Google Plus: The Magic Isn’t Social, It’s Semantic by Christine Connors, Semanticweb.com (July 29, 2011)

Christine Connors said, that Google+ is “one of the subtlest and most user-friendly ontology development systems we’ve ever seen.”

This is why - "Why did I do so? Well, G+ follows some of the basic principles of linked data: it uses persistent HTTP URIs for people, Sparks (concepts) and posts. It allows you to indicate a relationship between to entities and give that relationship a type. It collects, and types, attributes about entities from the expected experts – the entities themselves."

The article is a real-life short course in entities and attributes.
