New features

  • Parallelized versions of PageRank and Personalized PageRank have been
    added. A demo is available in wiki-page-rank; see the website for
    more information on obtaining the required data.
  • Add a disk-based streaming minimal perfect hash function library. A
    sub-component of this is a small memory-mapped succinct data structure
    library for answering rank/select queries on bit vectors.
  • Much of our CMake magic has been moved into a separate project included
    as a submodule: https://github.com/meta-toolkit/meta-cmake, which can
    now be used in other projects to simplify initial build system
    configuration.

Bug fixes

  • Fix parameter settings in language model rankers not being range checked
    (issue #134).
  • Fix incorrect incoming edge insertion in directed_graph::add_edge().
  • Fix find_first_of and find_last_of in util::string_view.

Enhancements

  • forward_index now knows how to tokenize a document down to a
    feature_vector, provided it was generated with a non-LIBSVM analyzer.
  • Allow loading of an existing index where its corpus is no longer
    available.
  • Data is no longer shuffled in batch_train. Shuffling the data
    causes horrible access patterns in the postings file, so the data
    should instead shuffled before indexing.
  • util::array_views can now be constructed as empty.
  • util::multiway_merge has been made more generic. You can now specify
    both the comparison function and merging criteria as parameters, which
    default to operator< and operator==, respectively.
  • A simple utility classes io::mifstream and io::mofstream have been
    added for places where a moveable ifstream or ofstream is desired
    as a workaround for older standard libraries lacking these move
    constructors.
  • The number of indexing threads can be controlled via the configuration
    key indexer-num-threads (which defaults to the number of threads on
    the system), and the number of threads allowed to concurrently write to
    disk can be controlled via indexer-max-writers (which defaults to 8).
