2011-08-28: KDD 2011 Trip Report

Author:  Carlton Northern The SIGKDD 2011 conference took place August 21 - 24 at the Hyatt Manchester in San Diego, CA.  Researchers from all over the world interested in knowledge discovery and data mining were in attendance.  This conference in particular has a heavy statistical analysis flavor and many presentations were math intensive. I was invited to present my masters project research at the Mining Data Semantics (MDS2011) Workshop of KDD.  In this paper, we present an approach to find social media profiles of people from an organization.  This is possible due to the links created between members an organization. For instance, co-workers or students will likely friend each other creating hyperlinks between their respective accounts.  These links, if public, can be mined and used to disambiguate other profiles that may share the same names as those individuals we are searching for.  The following figure shows the amount of profiles found from the ODU Computer Science st

The Web Science and Digital Libraries Research Group is offering two classes for the fall 2011 semester. CS 895 Web-Based Information Retrieval will be offered on Tuesdays, 4:20-7:00 in room 2120 of the ECS building. This class will use the recent Croft, Metzler & Strohman book as the required text, and the Manning, Ragahavan, & Schutze book as the recommended text. By choosing the former book as the primary guide for the course, we are intentionally provided a strong engineering component to the class (i.e., a level of coding and development is expected) as opposed to just a theoretical exploration of information retrieval. CS 751/851 Introduction to Digital Libraries is not a prerequisite, but it would help to be familiar with the material covered in that class. Dr. Weigle will be teaching CS 795/895 Information Visualization on Thursdays, 9:30-12:15 in room 2120 of the ECS building. This class is a follow-on to the CS 796/896 Visual Analytics Seminar from last

On July 26, 2011, the Web Science and Digital Library group at Old Dominion University hosted Kris Carpenter Negulescu, Director of the Web Group at the Internet Archive who gave a talk entitled “Universal Access to All Knowledge”. The presentation started with an introduction about what the Internet Archive is, then, she gave us some information about what are the archived materials in Internet Archive for now: Text (+2.9M books), Moving Images (+542,500 items), Audio (+950,000 items), Television broadcast (+1M hours), Web Pages (+150 billion pages). Moreover, she gave an overview about some of the special collections such as K-12 students and NASA images . After that, Kris explained the common collection strategies that are used by the Internet Archive to crawl the web. Frequently, they are doing a broad survey for the wide range domains such as .com, .net, .org, etc. They also considered the frequency of change for these websites and gave more support to the sites without
