Name        : openfst

Version     : 1.2.9
Release     : 1.fc15

Summary     : Weighted finite-state transducer library
Description :
OpenFst is a library for constructing, combining, optimizing, and
searching weighted finite-state transducers (FSTs).  Weighted
finite-state transducers are automata where each transition has an input
label, an output label, and a weight.  The more familiar finite-state
acceptor is represented as a transducer with each transition's input and
output label equal.  Finite-state acceptors are used to represent sets
of strings (specifically, regular or rational sets); finite-state
transducers are used to represent binary relations between pairs of
strings (specifically, rational transductions).  The weights can be used
to represent the cost of taking a particular transition.

FSTs have key applications in speech recognition and synthesis, machine
translation, optical character recognition, pattern matching, string
processing, machine learning, information extraction and retrieval among
others.  Often a weighted transducer is used to represent a
probabilistic model (e.g., an n-gram model, pronunciation model).  FSTs
can be optimized by determinization and minimization, models can be
applied to hypothesis sets (also represented as automata) or cascaded by
finite-state composition, and the best results can be selected by
shortest-path algorithms.

Update Information:

This release fixes the following bugs:
- Added FST_LL_FORMAT to fix 64-bit integer printf issues
- Fixed missing <functional> includes
- Fixed reused local variable names
- Fixed passing string by reference in FstDraw args

In addition, this release contains the following changes:
- Added StateMap/StateMapFst; renamed Map/MapFst to ArcMap/ArcMapFst; map/MapFst retained (but deprecated)
- Deleted ArcSum() and ArcMerge; use StateMap w/ ArcSumMapper and ArcUniqueMapper
- Incremented version of ConstFst/CompactFsts to stop memory alignment that fails on pipes. Made old version raises errors when read on pipes.
- Improved determinize hash


This update can be installed with the "yum" update program.  Use 
su -c 'yum update openfst' at the command line.
