Dear CLARIN-IT Members,

weare pleased to invite you to participate in the *First **GoTriple Hackathon*, which will take place *through MS Teams on 8**th**, 9th, 10**th***, ***15**th**and 16**th**November 2021* and will be preceded by a Preparatory Meeting scheduled for 3rd November 2021.

The goal of the GoTriple Hackathon is the improvement of the coverage of the Library of Congress Subject Heading (LCSH) in the GoTriple vocabulary.

Subject headings are specific words or phrases which are used in order to categorize and organize books and articles.

The LCSH is perhaps the most widely adopted subject indexing system in the world and has been translated into many languages.

Despite the fact that LCSH is the most translated Subject Headings System, there are discipline-specific vocabularies (i.e. selected lists of words which are used for the organization of knowledge) that have not yet been correlated to the LCSH.

The challenge for the groups that will take part in the GoTriple Hackathon is to find solutions to the problem of mapping between vocabularies in the languages that are represented in the TRIPLE Project (Croatian, English, French, German, Greek, Italian, Polish, Portuguese, Spanish) and LCSH.

Participation is open to software programmers with a dedicated interest in vocabularies, programming librarians, non-IT specialists working with managing vocabularies, people working in repositories and, of course, researchers.

A detailed description of the event along with a link to the registration form can be found here https://project.gotriple.eu/gotriple-hackathon-2021.

We would appreciate very much if you could join us and spread this information through your channels.
