Identity is fundamental to ontology, and especially to information systems ontologies. Identity is well known in metaphysics and in database conceptual modeling. In the latter case, it is an accepted best practice to specify a primary key for rows in a ta
If everyone would create good metadata for the purposes of describing their goods, services and information, it would be a trivial matter to search the Internet for highly qualified, context-sensitive results: a fan could find all the downloadable music i
It is important to differentiate between text data mining and information access (or information retrieval, as it is more widely known)... the goal of data mining is to discover or derive new information from data, finding patterns across datasets, and/o
Ever notice that before you can really do a good web search, you have to actually know something about your search topic? Let's say you want to learn more about jazz. But you don't know any of the "keywords," the musicians, the composers, the talent. S
Tagging is great...But can tagging be better? Yes. For example, how do you specify Paris (the city) as opposed to Paris (the person)? By using contextual tags (e.g.; celebrity:paris or city:paris) to give "thing" tags meaning. words are no longer stripp
This paper describes Seeker, a platform for large-scale text analytics, and SemTag, an application written on the platform to perform automated semantic tagging of large corpora. We apply SemTag to a collection of approximately 264 million web pages, and
Lexical ambiguity is a fundamental problem in Information Retrieval (IR), especially in the medical domain. Many systems use a subset of the words contained in the document to represent the content, but they are faced with the problem of ambiguity.
You maintain a blog at, say, livejournal.com (but this can be anything) and you stay logged in there usually. You go to leave a comment at someblog.com (perhaps it's Movable Type, or Wordpress, or DeadJournal, ...) and you don't have an account there, s
OpenID starts with the concept that anyone can identify themselves on the Internet the same way websites do-with a URI (also called a URL or web address). Since URIs are at the very core of Web architecture, they provide a solid foundation for user-centri
A great jump towards the advent of the Semantic Web will take place when a critical mass of web resources is available for use in a semantic way. This goal can be reached by the creation of semantic meta-data in the publication workflow, or by the develop
Blogging has a name, but I haven’t found a name for this programming-meets-blogging I like to do...Here’s a start: “blogramming.” The blogosphere has its a-list — so does the, um, blogrammosphere (ouch!)...we are all hooked on the thrill of hatc
It might seem redundant to have semantic tagging when you can basically find anything you can think of with simple searches in Google or Yahoo. But del.icio.us seems to be most surprising when you're trying to find things that relate to what you're intere
Category search within digital repositories is poorly supported. This means that people wishing to access the assets of digital repositories are largely limited to keyword search, which means they must know what they want in order to look for it. Our part
The introduction of semantics on the web will lead to a new generation of services based on content rather than on syntax. |:| Effective semantic search engines will provide means for successful searches avoiding the heavy burden experimented by users in
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
OpenID is a lightweight, decentralized identity system that has been gaining prominence. I expect this upcoming year to be a big year for OpenID -- and not just because of the Google trend chart with the recent uptake in search query share.

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 discussion of XML and semantics kicks off a column by Uche Ogbuji on knowledge management aspects of XML, including metadata, semantics, Resource Description Framework (RDF), Topic Maps, and autonomous agents. Approaching the topic from a practical p
Repeat after me: "There is no syntax." In order to use and gain advantage from RDF, you do not have to use any particular syntax -- not even the syntax specified in the RDF 1.0 specification. Uche Ogbuji discusses the importance of XML/RDF interchange, of
