This article describes methods for semiautomatic thesaurus construction, for a cross generation, cross genre, and cross cultural corpus. Semiautomatic thesaurus construction is a complex task, and applying it on a cross generation corpus brings its own challenges. We used a Jewish juristic corpus containing documents and genres that were written across 2000(More)
A cross-period (diachronic) thesaurus enables users to search for information using modern terminology and obtain semantically related terms from earlier historical periods. The complex task of supporting the construction of a diachronic thesaurus by a domain expert lexicographer has hardly been addressed computationally until now. In this article, we(More)
Corpus-based thesaurus construction for Morphologically Rich Languages (MRL) is a complex task, due to the morphological variability of MRL. In this paper we explore alternative term representations, complemented by clustering of morphological variants. We introduce a generic algorithmic scheme for thesaurus construction in MRL, and demonstrate the(More)
Identification of Multi-Word Expressions (MWEs) lies at the heart of many natural language processing applications. In this research, we deal with a particular type of Hebrew MWEs, VerbNoun MWEs (VN-MWEs), which combine a verb and a noun with or without other words. Most prior work on MWEs classification focused on linguistic and statistical information. In(More)
A diachronic thesaurus is a lexical resource that aims to map between modern terms and their semantically related terms in earlier periods. In this paper, we investigate the task of collecting a list of relevant modern target terms for a domain-specific diachronic thesaurus. We propose a supervised learning scheme, which integrates features from two closely(More)
