This Action aims at improving linguistic representativeness, precision and computational efficiency of Natural Language Processing (NLP) applications. The Action focuses on the major bottleneck of these applications: Multi-Word Expressions (MWEs), i.e. sequences of words with unpredictable properties such as "to kick the bucket". These expressions, while appearing very often (up to 30% of human utterances are MWEs) are relatively poorly supported by NLP systems. This comes from different causes: MWEs are by nature heterogeneous (syntactic, morphologic and semantic phenomenon), available data are often unadapted (lack of annotated corpus), underestimated problem. Moreover, there is a fragmentation issue in Europe, where researchers work on distinct languages. PARSEME aims to use Europe’s multilingual heritage to cross boundaries and establish an excellence network on this topic. So far, about thirty European countries became members of the PARSEME Action, and can thus send researchers to scientific events promoted by PARSEME (summer schools, short-term scientific missions, workshops, etc.).
