Call For Papers

In MWE'09 we are interested in the overall process of dealing with MWEs, asking for original research related (but not limited) to the following four fundamental topics.

(1) Identification. Identification is a major problem for MWEs. The MWE identification task is to determine whether a MWE is used non-compositionally (figuratively) or compositionally (literally) in a particular context. The identification of MWEs by automated means is a difficult task, as it does not suffice to store the MWE into a dictionary database. Rule-based (morphosyntactic rules) and/or statistical approaches may be needed to identify MWEs in context.

(2) Interpretation. Semantic interpretation of MWEs, particularly noun compounds and determinerless prepositional phrases, is the task of determining the implicit semantic relation holding between the MWE's sub-components. This specific area is inviting research on (linguistically) identifying the semantic relations (SRs) and automatic SR interpretation in MWEs. The relation inventories used can be of different granularity and dependent on the particular type of MWE construction. In some cases, MWE's semantics can be also specified in terms of a suitable paraphrase.

(3) Disambiguation. Disambiguation (Semantic classification) is the task of specifying the semantics of MWEs based on an inventory of semantic relations. It tends to presuppose the ability to classify the (degree of) compositionality of MWEs and applies only to compositional MWEs. The aim is to specify the semantics of MWEs in terms of predefined semantic categories, e.g., in WordNet.

(4) Applications. Identifying MWEs in context and understanding their syntax and semantics is important for many natural language applications, including but not limited to question answering, machine translation, information retrieval, information extraction, and textual entailment. Still, despite the growing research interest, there are not enough successful applications in real NLP problems, which we believe is the key for the advancement of the field.

Submissions must describe substantial, original, and unpublished work. Submissions will be judged on correctness, originality, technical strength, significance and relevance to the conference, and interest to the attendees. Full papers may consist of up to eight (8) pages in total (references icluded) and will be presented orally. The deadline for paper submission is May 1, 2009 (GMT + 8).
The official style files for ACL/IJCNLP 2009 are available at: The workshop submissions should use the same formatting guidelines.
