Ukrainian authors’ terminology in the iSybislaw system (verb) The problem of authors’ terminology is well­-known to all iSybislaw developers. It inevitably forces them to find a compromise between their desire to represent the content of a document as fully as possible and the need to protect the system from being cluttered with non-­standard terminology. Recent publications in the journal Ukrainska mova (Ukrainian language) suggest that researchers are interested in a wide range of problems, in particular categorical-­functional descriptions of the verb. The article by S. Sokolova and O. Achylova discusses the problem of verb translation. The authors use the terms aspektualnist’ (aspectuality), rody diieslivnoi dii (lexical aspects, or Aktionsarten) and vydova neitralizatsiia (aspect neutralization). Modern Ukrainian dictionaries of linguistic terminology contain only the first two terms. In the iSybislaw system, the following keywords are used for this document: aspektualnist’ (aspectuality), diieslovo (verb) and fazovist’ (phasicity). The term vydova neitralizatsiia (aspect neutralization) is not included. This term is new and refers to a situation when the aspectual meaning of a verb is irrelevant in translation from Ukrainian into non-­Slavic languages. There is no need to include such terms in the iSybislaw system. The fact that the set of keywords used in iSybislaw relies on both the semantic potential of terms used in the indexed texts and terminological standards ensures efficient information retrieval.
