This Lemur project release brings Indri 5.6, Galago 3.5 and RankLib 2.3 updates. 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 7 (jdk 1.7.0). The java UIs require Java 7. We have tested using GCC 4.1.2 (CentOS 5.3 linux), 4.3.3 (Ubuntu 10.04 linux), 4.2.1 (OS/X), and Visual Studio 2010 and 2012 (Windows 7, WIN32 and x86_64). **Special Note** Users should pay close attention to matching the version of Indri used to build an index with the version used to query the Index in order to obtain accurate search results. FR#78 added an exception if the versions are mismatched. If you are using indexes built with a version earlier than 5.3 you must re-index your data with this version. In addition, all indexes built with a version earlier than 5.5 that used the Krovetz stemmer must be rebuilt. Indri additions include: Compilation support for VS2010 and VS2012 The ability to use a blacklist when using IndriBuildIndex Galago additions include: High level interface; single file index; RankLib additions include: Improved support cross-validation, analysis functionalities; Coordinate Ascent now takes into account validation data; cmd-line parameter update in the Analyzer class Bugs Fixed (see https://sourceforge.net/p/lemur/bugs/ for the complete tickets): BUG# 214 -- Galago NumberedPostingsPositionExtractor null exception 215 -- Indri OffsetAnnotationAnnotator drops tokens of length 2 or less at end of field 216 -- Galago RM expansion fails on empty result set 217 -- Indri Exception running dumpindex 'c' (compact) command 218 -- Indri InferenceNetwork::_evaluateIndex assert fails when given an empty MemoryIndex BUG -- don't throw an internal error when encountering a longrec_error.
