The third edition of the CLaDA-BG Conference will be held in Sofia, Bulgaria, on 26-28 June, 2024. CLaDA-BG is the Bulgarian national research infrastructure for resources and technologies for linguistic, cultural and historical heritage, integrated within CLARIN and DARIAH. Its mission is to provide access to the necessary resources and technologies that support research in the Social Sciences and Humanities (SSH). Modelling and linking of various types of knowledge and its contexts is crucial for successful research in the interdisciplinary field of resources and technologies related to language, culture and history. The conference aims to bring together Natural Language Processing See: http://en.wikipedia.org/wiki/Natural_language_processing developers, linguists, digital humanitarians, scholars, and all parties interested in knowledge modelling and linking data for research. Topics of interest include, but are not limited to: Problems in SSH – research methods, technological support Language technologies for sentiment analysis, semantic technologies, trust-worthiness of knowledge graphs, ethical challenges in digital SSH Knowledge Modelling and Elicitation for digital SSH Specific Language Resources and Technologies for historical texts, parliamentary records, speech and multimodal corpora, social media data The role of digital libraries, archives and museums in digital SS&H research Language Interface to Knowledge Graphs in SSH Knowledge-modelled and linked applications in SSH Large Language Models in DH Best practices and new trends in Knowledge Modelling and Linking for language, culture and history. CLARIN is proud to be well represented among the invited speakers: Darja Fišer (CLARIN European Research Infrastructure Consortium See: https://research-and-innovation.ec.europa.eu/strategy/strategy-2020-2024/our-digital-future/european-research-infrastructures/eric_en ), Maciej Piasecki (CLARIN-PL, Wroclaw University of Science and Technology, Poland), Pia Sommerauer (CLTL, VU University Amsterdam, the Netherlands.
