The Arabic language is one of the oldest languages in the world that presents its own features and challenges while searching for Arabic-based content. The most search systems for the Holy Quran is organized around words (contained in the target verses) rather than the concepts which those words denote. As a word denote many concepts (polysemy) and a concept can be denoted by many words (synony...

Nearor quasi-synonyms can have an important role in the task of Information Retrieval since they may help to address the problem of vocabulary mismatch between queries and documents. One current approach to generating quasi-synonyms uses a general similarity measure to score the synonymy of two words based on their context vectors. In contrast, we compare two simple measures that take into acco...

The acquisition of semantic resources and relations is an important task for several applications, such as query expansion, information retrieval and extraction, machine translation. However, their validity should also be computed and indicated, especially for automatic systems and applications. We exploit the compositionality based methods for the acquisition of synonymy relations and of indic...

For fine-grained sentiment analysis, we need to go beyond zero-one polarity and find a way to compare adjectives (synonyms) that share the same sense. Choice of a word from a set of synonyms, provides a way to select the exact polarityintensity. For example, choosing to describe a person as benevolent rather than kind1 changes the intensity of the expression. In this paper, we present a sense b...

This article examines the effects of synonymy (i.e., learning words with and without high-frequency synonyms that were known to the learners) on word knowledge in a study of 84 Japanese students learning English. It employed 10 tests measuring 5 aspects of word knowledge (orthography, paradigmatic association, syntagmatic association, meaning and form, and grammatical functions) to assess learn...

The Indian assassin bug, Ectomocoris simulans Distant, 1919 (Hemiptera: Hetero- ptera: Reduviidae: Peiratinae) is redescribed, with habitus images and figures of male genitalia provided. melanopterus 1919, syn. nov., E. xavierei Vennison & Ambrose, 1990, are placed as its junior subjective synonyms. Types the above three nominal species were examined, illustrated, lectotypes designated.

In this paper, we propose an automatic and autonomous methodology to discover taxonomies of terms from the Web and represent retrieved web documents into a meaningful organization. Moreover, a new method for lexicalizations and synonyms discovery is also introduced. The obtained results can be very useful for easing the access to web resources of any medical domain or creating ontological repre...

Acquisition and enrichment of lexical resources is an important research area for the computational linguistics. We propose a method for inducing a lexicon of synonyms and for its weighting in order to establish its reliability. The method is based on the analysis of syntactic structure of complex terms. We apply and evaluate the approach on three biomedical terminologies (MeSH, Snomed Int, Sno...

Web search engines are a great help for accessing web sites but they present several problems regarding semantic ambiguity. In order to solve them, we propose new methods for polysemy disambiguation of web resources and discovery of lexicalizations and synonyms of search queries.

Species of the Afrotropical genus Dudaia Hedicke, 1923 of the subfamily Copromyzinae are revised. The status of Afroborborus Curran, 1931 as a junior synonym of Dudaia is corroborated. Twelve species have been described hitherto, two of them are proposed here to be junior synonyms: Copromyza (Dudaia) simulatilis Richards, 1980, and the name it replaced, Borborus (Dudaia) similis Vanschuytbroeck...
