develops the novel search ranking algorithm based on auto discovered and topic focused expert pages, and the innovative result presentation interface with discussion threads. Given a list of search result, PopGist discovers topic specific expert pages, fetches pages in the result list, analyzes them in multiple dimensions and detects spam pages, then reranks and presents them in threaded format. PopGist improves the relevancy of the existing search engines and provides better user search experience.”
ConceptNet is a freely available commonsense knowledgebase and natural-language-processing toolkit which supports many practical textual-reasoning tasks over real-world documents right out-of-the-box (without additional statistical training) including
DBin is a Semantic Web application that enables groups of users
with a common interest to cooperatively create semantically
structured knowledge bases. These user groups, which we call
“Semantic Web Communities”, are made possible by creating
customized user environments called “Brainlets”. Brainlets
provide user interfaces and domain specific tools (e.g. querying,
viewing and editing facilities) which enable community
participants to interact with the data of interest. Brainlets are
directly created by domain experts using an XML description
language. DBin clients communicate and exchange annotations
using a P2P infrastructure. Access control and digital signatures
put by DBin inside the authored RDF enable trust and information
filtering. In this paper we show a specific use case where a
“Semantic Web Community” is created to enable a group of users
to share their del.icio.us tags and organize them into a
cooperatively built RDFS ontology.
I posted an updated tech demo of RhNav - Rhizome Navigation visualizing user behavior of this blog. The graph is now centered around the page where most time is spent. Noise created by search engine robots is filtered which should clear things up quite a
Using RhNav - Rhizome Navigation I wrote a data aggregator for Technorati's API. The first result is a video which visualizes blog domains by analysing Technorati's Cosmos (the blogs which link to a particular URL). The video is a screencast of RhNav fetc
