libalinga is a C++ implementation of a multi-stream codec for the ALingA (Aligned Linguistic Annotation) format. It makes use of libogg++. Each ALingA stream holds at least one stream of annotation data, which is in the LingA format. It may also interleave the signal stream(s) against which the LingA streams are aligned, or it may simply reference such streams. It also provides metadata about the underlying manifold for the signals and the annotations. The metadata is ordered for runtime parsing of the number and type of signal and LingA codecs to enable decoding of the multiple logical streams in one pass.
transtoba2 facilitates the transliteration or transcription of a word or text from the Roman script into the Toba Batak script. Transliterating from the Roman into the Batak script is not an easy undertaking, as the Batak script has a number of peculiarities that complicates the process of transliteration. This program uses a set of algorithms which enables the user to effortlessly transliterate from the Roman to the Toba Batak script.
Apertium is a machine translation platform, initially aimed at related-language pairs, but recently expanded to deal with more divergent language pairs (such as English-Catalan). The platform provides a language-independent machine translation engine, tools to manage the linguistic data necessary to build a machine translation system for a given language pair, and linguistic data for a growing number of language pairs.
Algraeph is a tool for manual alignment of linguistic graphs, such as phrase structure trees or dependency structures, where each node corresponds to a subsequence of the analyzed input sentence. It allows you to express the similarity between two graphs by aligning their nodes and attaching relation labels to these alignments. Graphs are read from one or more graphbanks (or treebanks) in the GraphML or Alpino formats. Alignment relations are user-defined and are stored in a simple XML format, which can be used for further processing. The resulting parallel graph corpus is a useful data set for many tasks in computational linguistics and natural language processing.
Grammar Browser provides a simple-to-use graphical interface to the grammatical structure and relations of any text, as parsed by the Stanford Parser. It contains a grammatical relation editor to modify, import, and export grammatical relation definitions (tregex patterns and features).
Cypher is an AI program that generates the RDF graph and SPARQL query representations of plain language input, allowing users to speak plain language to update and query databases. With robust definition languages, Cypher's grammar and lexicon can quickly and easily be extended to process highly complex sentences and phrases of any natural language, and can cover any vocabulary. Equipped with Cypher, programmers can begin building next generation semantic Web applications that harness natural language.
OpenEphyra is a question answering (QA) system. It retrieves answers to natural language questions from the Web and other sources. OpenEphyra comes with implementations of algorithms that proved effective in Carnegie Mellon's Ephyra system, which participated in the TREC evaluations. It is platform independent and can be set up in just a few minutes. The goal of this project is to give researchers the opportunity to develop new QA techniques without worrying about the end-to-end system.
UnicodeDataBrowser is a browser for the UnicodeData.txt file, which contains much useful information but is not easily read by humans. It creates a scrollable table in which columns represent properties. The table may be sorted on any column. Abbreviations are expanded and characters cross-referenced in decomposition and casing fields are named. Regular expression search restricted to a selected column is available. The set of characters for which information is displayed may be restricted to those characters matching a regular expression on a specified property.
