Moses (machine translation)
Encyclopedia
Moses is a free software
statistical machine translation
engine that allows automatically training translation models for any language pair given a collection of source and target text pairs (parallel corpus). It is released under the LGPL licence and available both as source code and binaries for Windows
and Linux
.
Amongst its features are:
Moses development is, amongst other international organisations, mainly supported by EuroMatrix project and funded by the European Commission
.
Free software
Free software, software libre or libre software is software that can be used, studied, and modified without restriction, and which can be copied and redistributed in modified or unmodified form either without restriction, or with restrictions that only ensure that further recipients can also do...

Statistical machine translation
Statistical machine translation is a machine translation paradigm where translations are generated on the basis of statistical models whose parameters are derived from the analysis of bilingual text corpora...

Microsoft Windows
Microsoft Windows is a series of operating systems produced by Microsoft.Microsoft introduced an operating environment named Windows on November 20, 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces . Microsoft Windows came to dominate the world's personal...

Amongst its features are:
- beam-searchBeam searchIn computer science, beam search is a heuristic search algorithm that explores a graph by expanding the most promising node in a limited set. Beam search is an optimization of best-first search that reduces its memory requirements...
: an efficient search algorithm that quickly finds the highest probability translation among the exponential number of choices - phrase-based: the state-of-the-art in statistical machine translation allows the translation of short text chunks
- factored: words may have factored representation (surface forms, lemma, part-of-speech, morphology, word classes...)
- decoding of confusion networks, enabling easy integration with ambiguous upstream tools, such as automatic speech recognizers
- novel factored translation models, which enable the integration of linguistic and other information at many stages of the translation process
- support for large language modelsLanguage modelA statistical language model assigns a probability to a sequence of m words P by means of a probability distribution.Language modeling is used in many natural language processing applications such as speech recognition, machine translation, part-of-speech tagging, parsing and information...
: Moses can use language models such as IRSTLM (an exact LM using memory-mapping) and RandLM (a randomised LM, based on Bloom FiltersBloom filterA Bloom filter, conceived by Burton Howard Bloom in 1970, is a space-efficient probabilistic data structure that is used to test whether an element is a member of a set. False positives are possible, but false negatives are not; i.e. a query returns either "inside set " or "definitely not in set"...
