Update (1st June 2020)

The CLIB 2020 Organising Committee is glad to announce that the 4th International Conference on Computational Linguistics in Bulgaria will take place on 25 and 26 June 2020. There will be two modes of attendance: in person or online.  

The dates were selected in accordance with the latest regulations issued by the Minister of Health of the Republic of Bulgaria, allowing conferences to be held in compliance with the imposed anti-epidemic measures. In making this decision we have taken into consideration the lack of reliable long-term prognostications regarding the duration of the existing restrictions on travelling and the participation in full-scale scientific events worldwide.

Details will follow shortly.

We are pleased to announce the Fourth International Conference on Computational Linguistics in Bulgaria and the Call for Papers for this issue.

CLIB is an international conference that aims to foster the NLP community in Bulgaria and to further the cooperation with Bulgarian researchers working in NLP around the world through establishing a forum for sharing high-quality scientific work in all areas of computational linguistics and NLP.

The Fourth CLIB Conference will be held 8 – 9 June 25 – 26 June 2020 in Sofia, Bulgaria.

A special session dedicated to wordnets and ontologies will be held at CLIB 2020. This will be its second edition after a successful start at CLIB 2018. The Special Session brings together researchers interested in the principles, theory, practice and applications of wordnets, ontologies, related linguistic resources and their interoperability and seeks to establish a dedicated community and to foster joint initiatives in this particular field.

The CLIB 2020 Special Session on WordNets and Ontologies is held as part of the project Towards a Semantic Network Enriched with a Variety of Semantic Relations funded by the National Science Fund of the Republic of Bulgaria under the Fundamental Scientific Research Programme.

CLIB is organised by the team of the Department of Computational Linguistics at the Institute for Bulgarian Language and the Institute of Information and Communication Technologies at the Bulgarian Academy of Sciences (BAS).

Selected papers will be published in Cybernetics and Information Technologies Journal. The journal is indexed in SCOPUS and WoS. Its SJR for 2018 is 0.215.
