Multiword Expressions and Named Entities in the Wiki50 Corpus
Veronika Vincze, István Nagy T., Gábor Berend · 2011
Multiword expressions (MWEs) and named entities (NEs) exhibit unique and idiosyncratic features, thus, they often pose a problem to NLP systems. In order to facilitate their identification we developed the first corpus of Wikipedia articles in which several types of multiword expressions and named entities are manually annotated at the same time. The corpus can be used for training or testing MWE-detectors or NER systems, which we illustrate with experiments and it also makes it possible to investigate the co-occurrences of different types of MWEs and NEs within the same domain. 1
