New Semantic Search Engine
A new semantic search engine that classifies and analyzes the meaning of text has been developed by NEC. Now users will be able to locate text related to a keyword by referencing keyword aspects, thus enabling a more dynamic search result.
Read MoreLeveraging Your Taxonomy – Part 8
As we continue the series on search and how it works we are looking at file indexes more completely, more specifically complex inverted file indexes.
Stemming is the de-pluralization or removing the gerund endings. It is also called lemmatization. Truncation – left and right – are popular parts of search. Right, in some cases, chopping a word off at its end; is pretty easy. Left-hand truncation is hard because if you look at this wild card in the word ‘organization’ which can be spelled with either an ‘s’ or a ‘z’, depending on where you are from, the ‘-ation’ can be chopped off pretty easily but the right part, I have to build an entire index, starting with o, or, org, org, so that I can go through all of those to see where the full extension is. When people do left-hand truncation, it is a lot more expensive. It is a much bigger, additional index.
Read MoreThe Impact of Additional Delay
The Medical Group Management Association wants the Department of Health and Human Services to do more than delay ICD-10 implementation, they believe additional steps should be included in the ICD-10 timeline for what they call “due diligence.”
Read MoreDelay Causes Dissent
The topic of every conversation in healthcare organizations far and wide is the delay in the ICD-10 implementation. The pro-ICD-10 crowd insists ICD-10 should not be delayed and their voices are getting louder.
Read MoreSemantic Search Used in Discovery
PureDiscovery is combing their semantic discovery technology with LexisNexis® LAW PreDiscovery. This integration will help litigation discovery professionals find the most relevant documents faster than ever before. Semantic search technology allows the system to ‘learn’ as litigation documents are uploaded and searched. By applying the intelligence gathered to run smarter searches and help produce precise search results, the results will be much more comprehensive.
Read MoreDelay or No Delay?
A recent survey by Edifecs reports that about two-thirds of health care professionals do not believe a delay in ICD-10 implementation will improve readiness for the new coding standards. This is disheartening considering U.S. health care organizations are working to transition from ICD-9 to ICD-10 code sets to accommodate codes for new diseases and procedures. The switch from about 14,000 codes for about 69,000 codes was supposed to be done by October 1, 2013.

Nature Publishing Group has chosen Molecular Connections to carry out ontology enhancements for its key subject terms and semantic tagging for its back files.
Read MoreData Standard Models in Competition
Open Data Model is a fairly new organization, at least compared to EDM Council. But these competing models have been busy lately. EDM set out classifications based on asset class distinctions as the basis for its model. Open Data’s model is based on the ISO 10962 standard and the same organizing principles as Wikipedia.

Explaining a taxonomy as a “knowledge organization system,” our very own Margie Hlava explains how they are used to control the use of terms used in a subject field into a “vocabulary” to facilitate the storing and retrieving of items from a repository.

The National Federation of Advanced Information Services (NFAIS) released a draft code of practice for discovery services. The draft does make progress toward documenting the facing challenges, but falls short when it comes to handling the underlying reasons for those challenges.
