Modeling syntactic properties of MWEs in LFG

Il s'agit d'un réunion du réseau COST IC1207 PARSEMEThis paper describes preliminary investigationson how to model syntactic properties of differ-ent types of MWEs within the framework of LFG.While there are already several works which ad-dress this topic (Attia, 2006; Asudeh et al., 2013;Patejuk, 2014), we are particularly interested inanswering the question of which types of MWEscan be described at the level of the lexicon, andwhich (if any) require corresponding descriptionsat the level of phrase-structure rules

Enhancing practical TAG parsing efficiency by capturing redundancy

International audienceParsing efficiency within the context of tree adjoining grammars (TAGs) depends not only on the size of the input sentence but also, linearly, on the size of the input TAG, which can attain several thousands of elementary trees. We propose a factorized, finite-state TAG representation which copes with this combinatorial explosion. The associated parsing algorithm substantially increases the parsing performance on a real-size French TAG grammar

Promoting multiword expressions in A* TAG parsing

International audienceMultiword expressions (MWEs) are pervasive in natural languages and often have both idiomatic and compositional readings, which leads to high syntactic ambiguity. We show that for some MWE types idiomatic readings are usually the correct ones. We propose a heuristic for an A* parser for Tree Adjoining Grammars which benefits from this knowledge by promoting MWE-oriented analyses. This strategy leads to a substantial reduction in the parsing search space in case of true positive MWE occurrences, while avoiding parsing failures in case of false positives

Representation and parsing of multiword expressions: Current trends

This book consists of contributions related to the definition, representation and parsing of MWEs. These reflect current trends in the representation and processing of MWEs. They cover various categories of MWEs such as verbal, adverbial and nominal MWEs, various linguistic frameworks (e.g. tree-based and unification-based grammars), various languages including English, French, Modern Greek, Hebrew, Norwegian), and various applications (namely MWE detection, parsing, automatic translation) using both symbolic and statistical approaches
