The Impact Centre of Competence provides historical and named-entities lexica for the following languages. In addition, we offer access to the different corpora:
The current lexicon consists of 28,857 lexical entries developed in LeXtractor.
The period covered by the Historical Lexicon of English is since 1497 until 1900.
The German historical corpus consists of 510 texts varying in length and including different genres.
Fourteen works of Spanish Literature and a dictionary were selected for the IMPACT Demonstrator dataset.
IMPACT-es diachronic corpus of historical Spanish compiles over one hundred books. A complementary lexicon which links more than 10 thousand lemmas.
Corpora search services
Diasearch is an online service which enables users to perform linguistically enriched queries on a collection of historical texts. It is currently available for the Spanish IMPACT-es corpus.
What is a lexicon?
A lexicon is a structured, machine-usable repository of relevant linguistic knowledge about words in a language. A lexicon will contain historical variants (orthographical variants, inflected forms) and link them to a corresponding dictionary form in modern spelling (known as a ‘modern lemma’). In this way, a user can search for a modern word (‘water’) and receive results that take into account all historical variants in that language (‘wæter’, ‘weter’, ‘waterr’, ‘watre’, etc.)
The download of these resources are available for members of the Impact Centre of Competence and registered users.
