MISA: Multilingual "ISA" extraction from corpora

In this paper we present Multilingual IsA (MIsA), which is a collection of hypernymy relations in five languages (i.e., English, Spanish, French, Italian and Dutch) extracted from the corresponding full Wikipedia corpus. For each language, we first established a set of existing (viz. found in literature) or newly defined lexico-syntactic patterns. Similarly to WebIsADb, the resulting resource contains hypernymy relations represented as "tuples", as well as additional information such as provenance (Gil and Groth, 2011), context of the extraction, etc. To measure the precision of the patterns, we performed a manual assessment of the quality of the extracted relations and an error analysis. In addition, we release the software developed for the extraction of the hypernym tuples.
