"Ivan Herman discusses Semantic Web activity at the World Wide Web Consortium"

Collection of publications on the activities involving the semantic web. This is a very useful resource.

The Semantic Web Awareness Barometer 2009 aims at providing the reader with a brief overview over current trends and possible future topics in the fast evolving and dynamic field of web semantics. It also addresses Social Software, since these two areas are expected to condition each other. The data analysed in this survey was primarily collected among Semantic Web specialists from science and industry.

"The fourth of July holiday is upon us. And this year, why not celebrate democracy by checking out the open source project GovTrack.us, a site where you can follow the status of federal legislation and members of Congress? The government, of course, puts lots of data about the activities of the U.S. Congress on the web. THOMAS, for example, provides legislative information from the Library of Congress. But much of the time, the user interfaces to sites like this are less than optimal, and the data in each exists in its own individual silo. GovTrack.us is one graduate student's attempt to change the experience when it comes to getting information on pending legislation (and about a decade's worth of historical data on the topic), both in terms of a more accessible interface and pulling together data on the topic from multiple government sources.

"The company is Israel-based MindCite, and its semantic-based software lets homeland security agencies and intelligence agencies collect, integrate, research, and analyze diverse types of information, from structured formats like databases and unstructured formats such as text, to solve crimes, crack cases and get alerts. The company's systems are installed in over a dozen countries, though not stateside yet. "

"The Voice of Semantic Web Business & Technology"

"Mainstream businesses increasingly are taking the semantic web seriously. Consider the U.K. Governments Technology Program's Market Blended Insight (MBI) project. While funded under that program as a three-year applied research project, it includes as part of its consortium the marketing departments of ParcelForce Worldwide, British Gas Business, AXA, Clydesdale and Yorkshire Bank (NAGE), 3M and pH Group. Having these partners on board helps ensure that the work it is doing to help companies improve their marketing activities has application in real-world scenarios. "

"While some people work heavily on the extension of the semantic web infrastructure, like Talis Connected Commons or OpenLink´s Amazon EC2 Instantiation others have started to bring the semantic web closer to the developers and therefore to a much broader audience: They offer search facilities or Linked Data Navigators like OpenLink´s Entity Finder or DERI´s VisiNav."

"Andreas Blumauer (Semantic Web Company) talked with Brian Donnelly about a new system on the market called "Semantic Discovery System" (SDS), which helps to do sophisticated queries across existing datasets. Also talking why complex scripts or triple stores should not be exposed to the end-users anymore."

"During the early days of the Internet in the mid and late 90's software professionals and Internet users waited in angst for computers to become as smart as people by using artificial intelligence (computers using human reason combined with processing power thousands of times faster than human brain's processing power). This never panned out [...]"

"The Disco - Hyperdata Browser is a simple browser for navigating the Semantic Web. The browser renders all information, that it can find on the Semantic Web about a specific resource, as an HTML page. This resource description contains hyperlinks that allow you to navigate between resources. While you move from resource to resource, the browser dynamically retrieves information by dereferencing HTTP URIs and by following rdfs:seeAlso links."

"DBpedia is a community effort to extract structured information from Wikipedia and to make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia, and to link other data sets on the Web to Wikipedia data."

What are the big players doing in semantic search? And which of the startups are challenging them? How does semantic technology change search results? What are the key advantages and new opportunities that semantics provides in both the consumer and business search markets?

In this article, we'll analyze the trends and technologies that power the Semantic Web. We'll identify patterns that are beginning to emerge, classify the different trends, and peak into what the future holds.

Latent Semantic Analysis @ CU Boulder Demonstration tools that use LSA.

Thomas K Landauer, Department of Psychology, University of Colorado at Boulder Peter W. Foltz, Department of Psychology, New Mexico State University Darrell Laham, Department of Psychology, University of Colorado at Boulder Latent Semantic Analysis (LSA) is a theory and method for extracting and representing the contextual-usage meaning of words by statistical computations applied to a large corpus of text (Landauer and Dumais, 1997). The underlying idea is that the aggregate of all the word contexts in which a given word does and does not appear provides a set of mutual constraints that largely determines the similarity of meaning of words and sets of words to each other. The adequacy of LSA's reflection of human knowledge has been established in a variety of ways. For example, its scores overlap those of humans on standard vocabulary and subject matter tests; it mimics human word sorting and category judgments; it simulates word<>word and passage<>word lexical priming data; and, as reported in 3 following articles in this issue, it accurately estimates passage coherence, learnability of passages by individual students, and the quality and quantity of knowledge contained in an essay.
