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)
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)
Cross-period (diachronic) thesaurus construction aims to enable potential users to search for modern terms and obtain semantically related terms from earlier periods in history. This is a complex task not previously addressed computationally. In this paper we introduce a semi-automatic iterative Query Expansion (QE) scheme for supporting cross-period(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)
