Debian Science Linguistics packages

An open-source shallow-transfer machine translation engine, Apertium is initially aimed at related-language pairs.

It uses finite-state transducers for lexical processing, hidden Markov models for part-of-speech tagging, and finite-state based chunking for structural transfer.

The system is largely based upon systems already developed by the Transducens group at the Universitat d'Alacant, such as interNOSTRUM (Spanish-Catalan, http://www.internostrum.com/welcome.php) and Traductor Universia (Spanish-Portuguese, http://traductor.universia.net).

It will be possible to use Apertium to build machine translation systems for a variety of related-language pairs simply providing the linguistic data needed in the right format.

This package contails Perl scripts to evaluate Apertium-based machine translation output against reference: WER, PER, TER, BLEU.

Module for compiling lexical selection rules and processing them in the pipeline.

Artha is a off-line English thesaurus with distinct features like:

• hot-key press word look-up (select text on any window and press a preset hot-key for look-up)
• regular expressions based search (broaden search using wild-cards like *, ?, etc.)
• passive desktop notifications (of word definitions for uninterrupted work-flow)
• spelling suggestions (when the exact spelling is vague/not known)

Once launched, it monitors for a preset hot-key combination. When some text is selected on any window and the hot-key is pressed, it pops-up with the word looked-up. Should the user prefer passive notifications, this can be done by enabling the notifications option.

When the term looked for is vague/not known, then either the search can be broadened with the use of regular expressions (*, ?, etc.) in the search string or spelling suggestions when a term is incorrect.

For regular expressions based search to work, wordnet-sense-index package is required.

Constraint Grammar compiler and applicator for the 3rd edition of CG that is developed and maintained by VISL SDU and GrammarSoft ApS.

CG-3 can be used for disambiguation of morphology, syntax, semantics, etc; dependency markup, target language lemma choice for MT, QA systems, and much more. The core idea is that you choose what to do based on the whole available context, as opposed to n-grams.

See https://visl.sdu.dk/cg3.html for more documentation

Collatinus can be used to lemmatise latin texts, i.e. extract words and make a lexicon which indicates for each word its canonic form, and how the form actually found in the text was derived from it, for instance by declining it. Example : rosam gives : rosa-rosae -- acc. sing. Collatinus provides a nice graphic front-end to each operation.

Collatinus-nouus (stands for Collatinus, new generation) replaces every previous version of Collatinus.

This package provides a documentation in HTML format.

Dimbl is a wrapper around the k-nearest neighbor classifier in TiMBL, offering parallel classification on multi-CPU machines. Dimbl splits the original training set, builds separate TiMBL classifiers per training subset, and merges their nearest-neighbor sets per classified instance

• Wraps neatly around TiMBL, retaining all command line options;
• Knows what to do with your multiple, duo, or quad cores;
• Makes use of the OpenMP specification for parallel programming;
• Can attain superlinear speed gains compared to standard TiMBL.

Frog is a modular system integrating a morphosyntactic tagger, lemmatizer, morphological analyzer, and dependency parser for natural languages. It is based upon it's predecessor TADPOLE (TAgger, Dependency Parser, and mOrphoLogical analyzEr). Using Memory-Based Learning techniques, frog tokenizes, tags, lemmatizes, and morphologically segments word tokens in incoming UTF-8 text files, and assigns a dependency graph to each sentence. Frog is particularly targeted at the increasing need for fast, automatic NLP systems applicable to very large (multi-million to billion word) document collections that are becoming available due to the progressive digitization of both new and old textual data. Up to now, frog has only been tested and used using corpora of Dutch natural language (see the frogdata package for samples).

Frog is a product of the Centre of Language and Speech Technology at Radboud University Nijmegen, it subsumes previous work by the ILK Research Group (Tilburg University, The Netherlands) and the CLiPS Research Centre (University of Antwerp, Belgium). It is currently maintained at the KNAW Humanities Cluster.

If you do scientific research in NLP, Frog will likely be of use to you.

In Sleator, D. and Temperley, D. "Parsing English with a Link Grammar" (1991), the authors defined a new formal grammatical system called a "link grammar". A sequence of words is in the language of a link grammar if there is a way to draw "links" between words in such a way that the local requirements of each word are satisfied, the links do not cross, and the words form a connected graph. The authors encoded English grammar into such a system, and wrote this program to parse English using this grammar.

link-grammar can be used for linguistic parsing for information retrieval or extraction from natural language documents. It can also be used as a grammar checker.

This package contains the user-executable binary.

The lttoolbox contains the augmented letter transducer tools for natural language processing used by Apertium, a platform for building rule-based and hybrid machine translation systems.

MBT is a memory-based tagger-generator and tagger in one. The tagger-generator part can generate a sequence tagger on the basis of a training set of tagged sequences; the tagger part can tag new sequences. MBT can, for instance, be used to generate part-of-speech taggers or chunkers for natural language processing. Features:

• Tagger generation: tagged text in, tagger out,
• Optional feedback loop: feed previous tag decision back to input of next decision,
• Easily customizable feature representation; can incorporate user-provided features,
• Automatic generation of separate sub-taggers for known words and unknown words,
• Can make use of full algorithmic parameters of TiMBL.

The Apache OpenNLP library is a machine learning based toolkit for the processing of natural language text. It supports the most common NLP tasks, such as tokenization, sentence segmentation, part-of-speech tagging, named entity extraction, chunking, parsing, and coreference resolution. These tasks are usually required to build more advanced text processing services. OpenNLP also included maximum entropy and perceptron based machine learning.

This package contains the command line wrapper.

An R implementation of the LexRank algorithm implementing stochastic graph-based method for computing relative importance of textual units for Natural Language Processing. The technique on the problem of Text Summarization (TS) is tested. Extractive TS relies on the concept of sentence salience to identify the most important sentences in a document or set of documents. Salience is typically defined in terms of the presence of particular important words or in terms of similarity to a centroid pseudo-sentence.

WordNet(C) is an on-line lexical reference system whose design is inspired by current psycholinguistic theories of human lexical memory. English nouns, verbs, adjectives and adverbs are organized into synonym sets, each representing one underlying lexical concept. Different relations link the synonym sets.

WordNet was developed by the Cognitive Science Laboratory at Princeton University under the direction of Professor George A. Miller (Principal Investigator).

WordNet is considered to be the most important resource available to researchers in computational linguistics, text analysis, and many related areas.
