General-purpose releases

These releases should compile under any version of Linux with gcc 3.0 or greater. If they do not, please send me an email.

• Wumpus 2007-11-23 (.tar.gz, 1089 KB)
  This release fixes some minor problems as well as an annoying off-by-one bug that sometimes showed up when fetching the text for a given index extent, and the text was not properly aligned with the index data.
  
  
• Wumpus 2007-09-07 (.tar.gz, 1102 KB)
  This release introduces a new on-disk index format. The new version can read the index files created by an older version, but older versions cannot process index files produced by the new version!

TREC Terabyte release

• Wumpus 2006-05-03-TREC (.tar.gz, 884 KB)
  Use this release if you want to do a performance baseline run for TREC Terabyte 2006. After downloading the package, untar it and chdir to the wumpus/ directory. Then type make. If the build process fails, please send me a bug report so that I can try to fix the problem. Under Linux, everything should work smoothly. After building the distribution, there are two run modes. From within the wumpus/ directory, execute
  • bin/trec INDEX input_file output_file log_file
    in order to build an index for the document collection. The index will be created in wumpus/database/. The command-line parameter input_file must refer to a file that contains a list of all files that are to be indexed (these files may either be plain text, .gz, or .bz2, but must be in TREC format). Nothing is written to the file given by output_file. Log messages, including performance information, are written to log_file.
  • bin/trec QUERY input_file output_file log_file
    in order to run search queries against the index built by following the instructions above. The command-line parameter input_file must refer to a file that contains all ad-hoc search queries that are to be executed. The queries in the input file must be of the format "topic_id term_1 term_2 .. term_N". To see the exact format, you can download a set of example queries. TREC-formatted search results are written to output_file. Log messages, including performance information, are written to log_file.
  System requirements: In order to perform a Wumpus performance baseline run for the GOV2 document collection, you need at least 512 MB of RAM and 40 GB of free hard disk space on the partition where you install Wumpus.
