Advantages of Collatinus

• efficiency of the lemmatization process (~1000 words/s. ; depends of course on the machine on which the program is running),
• lemmas from Lewis & Short 1879 and Gaffiot 2016 (with the author's permission) with translations into English and French. Collation with those from Georges 1913 and Jeanneau 2017 (with the author's permission),
• basic glossary of 24,155 lemmas (Classic texts from LASLA) and extension of 58,384 lemmas, with some additional variants and the assimilation of the prefix,
• classification of the lemmatizations and morphosyntactic analysis according to the number of occurrences observed in LASLA texts,
• translations of about 11,000 lemmas in 6 different languages, other than French and English (to be improved)
• ability to colourize a text according to a list of known words,
• scansion and accentuation of a word or text,
• probabilistic tagger based on statistics from LASLA texts (~1,800,000 words)
• access to dictionaries in text or image mode (djvu). Easy to add new dicos (djvu),
• ability to use Collatinus from another program (e.g. LibreOffice) via an internal port,
• ability to query Collatinus from a client in console mode. Lemmatization of a text from a file
• software source code refactored in a modular way in order to facilitate the development of more specific applications

Project History

Originally, Collatinus was meant to produce printed documents, and it is still used for this purpose. Further improvements and adjustments were made when it became apparent that many people were using it for other purposes:

1. as a lexical and morphological reference when reading a Latin text disposer,
2. for lexical and stylistic searches
3. to provide students with exercises based on Latin texts

How it Works

Unlike the majority of lemmatisers, which use lists of inflected forms, Collatinus uses a lexicon containing the lemmas and all the necessary information for their inflection. The advantage to this approach is that Collatinus, with its 11,000 lemmas, is capable of recognising over half a million forms. Adding lemmas with spelling variants (such as medieval spellings, for example) would make it possible to recognise all of their inflected forms as well.

Starting from a lemma and its associated flexional endings, Collatinus is also capable of displaying the corresponding inflection tables, which Latin learners may find useful.

Finally, when syllable quantities are known for a given lemma, Collatinus can scan the word and even the entire text. When scanning a text, Collatinus applies the usual rules of elision and hiatus.
