Here, we present OntoSem resources that are used for deep meaning analysis of Web pages. These resources include concepts (language independent) and lexicons (in English) that are utilized by the hakia's OntoSem parser (called hOntoParser). The illustrati
With this Web page, we are opening some aspects of hakia R&D to the view of our users. We undertook highly specific research tasks solely dedicated to the advancement of the core-competency in Web search. The main challenge is to make science work in a co

Semantic similarity, also called semantic relatedness or semantic closeness/proximity/nearness, is a concept whereby a set of documents or terms within term lists are assigned a metric based on the likeness of their meaning / semantic content.
Used for centuries for learning, brainstorming, memory, visual thinking, and problem solving...similar to a semantic network or cognitive map but no formal restrictions on kinds of links used.

Automatic semantic annotation of information content is an open problem, but is crucial to the realization of the Semantic Web. Annotation systems require the initial definition of an ontology and as well as a knowledge base. Both of these resources work
In this column, Uche Ogbuji completes his introduction to XML and semantics, setting the stage for the more practical columns that will follow. Thinking XML addresses knowledge management aspects of XML, including metadata, semantics, Resource Description
In the last two installments of my Thinking XML column, I covered semantic transparency -- the ability to share the meaning of the bits that go between those freewheeling XML angle brackets and quotation marks. Recent events in XML directly touch on the t

This guide contains links to many RDF resources including examples, documents, software, tools and projects that use RDF, a standard for describing resources on the web.
