MeTA v2.3.0

New features

• 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
  ├── fwd
  └── 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.

Bug fixes

• Fix rounding bug in language model-based rankers. This bug caused
  severely degraded performance for these rankers with short queries. The
  unit tests have been improved to prevent such a regression in the
  future.

Enhancements

• The bundled ICU version has been bumped to ICU 57.1.
• MeTA will now attempt to build its own version of ICU on Windows if it
  fails to find a suitable ICU installed.
• CI support for GCC 6.x was added for all three major platforms.
• CI support also uses a fixed version of LLVM/libc++ instead of trunk.
