Current synonym extraction methods work in a “closed” way. Given the problem word and set of target words, researchers have to choose words synonymous with the problem word using features such as lexical patterns and distributional similarities. This paper tries to discover synonyms in an “open” way and presents a synonym extraction framework based on self-supervised learning. We first analysis...

The genus Glyphidops Enderlein, 1922, the most widespread and speciose of the New World genera of Neriidae (Diptera), is revised herein. Glyphidops (Glyphidops) ruselatus, new species, G. (G.) steyskali, new species and G. (G.) coracinus, new species are described. Of the 16 previously described species, which were last treated by Aczél (1961), the following synonyms are proposed: Chaetomeriste...

We present a method for the extraction of synonyms for German particle verbs based on a word-aligned German-English parallel corpus: by translating the particle verb to a pivot, which is then translated back, a set of synonym candidates can be extracted and ranked according to the respective translation probabilities. In order to deal with separated particle verbs, we apply re-ordering rules to...

Concept mapping is important in natural language processing (NLP) for bioinformatics. The UMLS Metathesaurus provides a rich synonym thesaurus and is a popular resource for concept mapping. Query expansion using synonyms for subterm substitutions is an effective technique to increase recall for UMLS concept mapping. Synonyms used to substitute subterms are called element synonyms. The completen...

We present our ongoing work on creating fuzzy synsets for Swedish using the lexical resources Synlex and SALDO. Synlex is a graded synonym list created by asking members of the public – users of an online Swedish-English dictionary – to judge the degree of synonymy of a random, automatically generated synonym pair candidate. SALDO is a full-scale Swedish lexical-semantic resource with non-class...

The old technique of "abstraction and refinement" makes it possible to understand complex systems by describing them in successive levels of detail. On the other hand the more modern technique of "generalization and specialization" (or Inheritance) facilitates the construction of systems by enabling reuse of specifications. Both techniques enable developers to specify a taxonomic relationship b...

This paper describes a multilingual semantic search assistant (MSSA) that could help users find proper keywords in FAO fulltext-based search engines. The MSSA implements four independent functions each associated with the AGROVOC multilingual thesaurus to assist users in choosing better keywords: a Venn diagram-based Boolean search interface, an animated AGROVOC concept browser, cross-language ...
