Since 1995, the NLDB conference brings together researchers, industry practitioners, and potential users interested in various application of Natural Language in the Database and Information Systems fields.

The term “Information Systems” has to be considered in the broader sense of Information and Communication Systems, including Big Data, Linked Data and Social Networks.

The field of Natural Language Processing (NLP) has itself recently experienced several exciting developments. In research, these developments have been reflected in the emergence of neural language models (Deep Learning, Word2Vec) and a (renewed) interest in various linguistic phenomena, such as in discourse and argumentation theory (argumentation mining). Regarding applications, NLP systems have evolved to the point that they now offer real-life, tangible benefits to enterprises. Many of these NLP systems are now considered a de-facto offering in business intelligence suites, such as algorithms for recommender systems and opinion mining/sentiment analysis as well as question-answering systems.

It is against this backdrop of recent innovations in NLP and its applications in information systems that the 26^th edition of the NLDB conference – NLDB2021, takes place. We welcome research and industrial contributions, describing novel, previously unpublished works on NLP and its applications across a plethora of topics as described in the Call for Papers.

NLDB 2021 is organized by the “Deutsches Forschungsinstitut für Künstliche Intelligenz” (DFKI) and the University of Saarland, Germany, from the 23. to 25 of June 2021.
