Workshop on Extracting and Using Constructions in NLP


Important dates | Location | Proceedings | Program committee | Program

A construction is a recurring, or otherwise noteworthy congregation of linguistic entities. Examples include collocations ("hermetically sealed"), (idiomatic) expressions with fixed constituents ("kick the bucket"), expressions with (semi-)optional constituents ("hungry as a X"), and sequences of grammatical categories ([det][adj][noun]). As can be seen by these examples, constructions are a diverse breed, and what constitutes a linguistic construction is largely an open question.

Despite (or perhaps due to) the inherent vagues of the concept, constructions enjoy increasing interest in both theoretical linguistics and in natural language processing. A symptom of the former is the Construction grammar framework, and a symptom of the latter is the growing awareness of the impact of constructions on different kinds of information access applications. Constructions are an interesting phenomenon because they constitute a middleway in the syntax-lexicon continuum, and because they show great potential in tackling infamously difficult NLP tasks.

We encourage submissions in all areas of constructions-based research, with special focus on:
