Motivation:  In order to organize the publicly available personal information on the web in a more structured way, and allow for advanced querying of the collected information, we have been developing a knowledgebase called PopulusLog. PopulusLog is a set of tools providing the capability for crawling, information extraction, and advanced querying. More specifically, PopulusLog (i) allows grouping of, and provides one-point access to the information about a person, (ii) provides semantic querying schemes like “Find the colleagues of person A” rather than just simple syntactical keyword search, (iii) evaluates the collected information thorough social network analysis and provide new knowledge like personal impact factors, social cliques that would otherwise stay implicit, (iv) visualizes the query results.

This prototype is a version of PopulusLog developed for the CASE (a.k.a. CWRU) domain. The PopulusLog CASE Edition features:

·         User authentication through Case Single Sign-on service

·         Allowing people to edit/curate automatically collected data, or totally remove their record

·         Locating personal home pages (if any)

·         Improved data cleaning techniques to minimize the false labeling of entities

·         Locating and listing similar people

·         Improved person-to-person relationship detection

·         Identifying virtual social network of a person

·         Computation of top-k most informative web pages about a person

·         A newly-designed, light-weight and simple visualization interface
