Lemur Toolkit 4.8 / Indri 2.8 Release

More catching up on end of year software releases. At the end of December version 4.8 of UMass and CMU's LEMUR language modeling toolkit, including version 2.8 of the Indri search engine, was released.

The new version has important fixes and enhancements. You can read the full release notes, but here are some highlights:
  • A new Java GUI for the ireval package
  • Critical fixes to the TextTokenizer (critical if you created indexes with Indri 2.7!)
  • The ModifyFields application to add or remove field data from an Indri Repository without complete reindexing
  • Improvements to the Query Log Toolbar
See the Lemur SourceForge page for download and the wiki documentation.
