NOTE I *will not* answer mails about internship/Masters/Ph.D. positions. Here's why: Our group no longer has 2-3 month internship positions. If you are a Ph.D. student, or looking for more than 5 months internship, say it in the subject of the mail. Otherwise, I delete all internship requests. For Masters/Ph.D. admissions, look at IMPRS-CS website, or Saarland University Graduate School website. I don't have any information.

NEW!

I am co-organizing the 2nd M3SN workshop on Modeling, Managing, and Mining Evolving Social Networks (colocated with ICDE'10). For details on the earlier edition of the workshop, please check out website. Watch for the new website details.

Software

1. Persistent Suffix-tree Construction through Ukkonen's Algorithm - Version 1.0
   Provides self-contained buffer management and persistent storage management modules. Also implements the high performing TOPQ algorithm for buffer management (for details refer to my paper "Engineering a Fast Online Persistent Suffix Tree Construction" that appeared in ICDE 2004).
   Note on efficiency: This code release is NOT speed-optimized. Please contact me if you need one.

• A Product Line Architecture for Word-of-Mouth Social Software
  M. Bharath Kumar and Srikanta Bedathur
  IISc-CSA-TR-2004-11, Dept. of Computer Science & Automation, Indian Institute of Science, 2004.
  This was part of the MetaVines Project, started out of realization that each of us were spending far too much time discovering the same stuff over and over again on the Web, and it would be more interesting if we could use the community intelligence to reduce those extra hours we "wasted" in front of the browser :-)
