This Lemur project release is for Indri 5.13, Galago 3.14, RankLib-2.10 and Sifaka-1.4.

Applications compiled with the Indri API require the following libraries:
   z, iberty, pthread, and m on linux. 

Applications built in Visual Studio require the additional library wsock32.lib.

The java jar files were built with Java 8 (jdk 1.8.0). The java UIs require Java 8.
We have tested using GCC 4.4.7 (CentOS 6.7 linux), 4.8.4 (16.04 linux),
4.2.1 (OS/X 10.11.3), and Visual Studio 2012 (Windows 7, WIN32 and x86_64).

Note that OS/X Yosemite (10.10) is not supported.  There are likely C++ library
issues for Indri compilation on OS/X Sierra (10.12) or High Sierra (10.13) systems.
Note also that Windows 10 is not yet supported.  Indri built with Visual Studio
beyond version 2012 has not been tested.

No further development is being done with Indri.


Features and Fixes

  Galago

  o Added showNoResults parameter to facilitate MAP (and other) evaluation metrics when no
    result queries occur (Bug #300, #301).  If this flag is set, an dummy document ID will be
    added to the retrieval results so it is known no results were found.  This allows evaluation
    metrics to fully evaluate over all queries in a set.  If the flag is not set, no result
    will be shown for no result queries.

  o Added appropriate build tests for no result queries.


  RankLib

  o Added feature_stats parameter for RankLib's FeatureManager.  This produces a distribution of
    use frequencies for features defined in a model as well as statistics on the frequency
    distributions.  This function is only for use in models that select a subset of available
    features to create the model (e.g. tree type algorithms).  Algorithms using the entire feature
    set are not processed.


  Indri

  o Added some tolerance to stemming parameters (Bug #301).  A <stemmer> parameter without
    a <name> tag will quietly build an unstemmed index.  Indri now accepts stemmer name with
    or without a <name> tag.
