DBpedia is a crowd-sourced community effort to extract structured information from Wikipedia and make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia, and to link the different data sets on the Web to Wikipedia data. We hope that this work will make it easier for the huge amount of information in Wikipedia to be used in some new interesting ways. Furthermore, it might inspire new mechanisms for navigating, linking, and improving the encyclopedia itself.

Querying DBpedia DBpedia, as its home page tells us, "is a community effort to extract structured information from Wikipedia and to make this information available on the Web." That's "available" in the sense of available as data to programs that read and process it, because the data was already available to eyeballs on Wikipedia. This availability is a big deal to the semantic web community because it's a huge amount of valuable (and often, fun) information that the public can now query with SPARQL, the W3C standard query language that is one of the pillars of the semantic web. Although I'd dabbled in SPARQL and seen several sample SPARQL queries against DBpedia in action, I had a little trouble working out how to create my own SPARQL queries against DBpedia data.

Nuclear[edit] A New Best Friend: Gephi for Large-scale Networks Though I never intended it, some posts of mine from a few years back dealing with 26 tools for large-scale graph visualization have been some of the most popular on this site. Indeed, my recommendation for Cytoscape for viewing large-scale graphs ranks within the top 5 posts all time on this site. When that analysis was done in January 2008 my company was in the midst of needing to process the large UMBEL vocabulary, which now consists of 28,000 concepts. Like anything else, need drives research and demand, and after reviewing many graphing programs, we chose Cytoscape, then provided some ongoing guidelines in its use for semantic Web purposes.

Tools This page gives an overview of software tools related to the Semantic Web or to semantic technologies in general. Due to the large amount of tools being created in the community, this site is always somewhat outdated. Contributions and updates are welcomed.

SOCIETY network analysis Social network analysis (SNA) is the analysis of social networks. Social network analysis views social relationships in terms of network theory, consisting of nodes (representing individual actors within the network) and ties (which represent relationships between the individuals, such as friendship, kinship, organizations, sexual relationships, etc.)[1][2] These networks are often depicted in a social network diagram, where nodes are represented as points and ties are represented as lines. Overview[edit] Social network analysis has emerged as a key technique in modern sociology. It has also gained a significant following in anthropology, biology, communication studies, economics, geography, history, information science, organizational studies, political science, social psychology, development studies, and sociolinguistics and is now commonly available as a consumer tool.[3][4][5][6]
