MeTA v2.3.0 Release Notes

Release Date: 2016-08-02 // over 4 years ago
  • ๐Ÿ†• New features

    ๐Ÿšš Forward and inverted indexes are now stored in one directory. To make use of your existing indexes, you will need to move their directories. For example, a configuration that used to look like the following

    dataset = "20newsgroups"corpus = "line.toml"forward-index = "20news-fwd"inverted-index = "20news-inv"
    

    will now look like the following

    dataset = "20newsgroups"corpus = "line.toml"index = "20news-index"
    

    and your folder structure should now look like

    20news-index
    โ”œโ”€โ”€ fwd
    โ””โ”€โ”€ inv
    

    You can do this by simply moving the old folders around like so:

    mkdir 20news-index mv 20news-fwd 20news-index/fwd mv 20news-inv 20news-index/inv
    

    stats::multinomial now can report the number of unique event types
    counted (unique_events())

    std::vector can now be hashed via hash_append.

    ๐Ÿ› Bug fixes

    • ๐Ÿ›  Fix rounding bug in language model-based rankers. This bug caused
      ๐ŸŽ severely degraded performance for these rankers with short queries. The

      future.

    โœจ Enhancements

      fails to find a suitable ICU installed.
    • ๐Ÿ‘ CI support for GCC 6.x was added for all three major platforms.
    • ๐Ÿ›  CI support also uses a fixed version of LLVM/libc++ instead of trunk.
