Update (20 March 2020)

In light of the COVID-19 pandemic and its impact on everyone’s life, we feel that the responsible thing to do is to postpone the conference until better times. Given the rapid unfolding of events, the exact dates for CLIB 2020 will be announced at a later point, but we are looking forward to reschedule the conference for late September 2020 and will be working hard to make this happen. The organisation will continue at full speed.

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 in late September 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).
