The paper proposes an approach to transcend multicultural and multilingual barriers in the use and reuse of geographical data at the European level. The approach aims at sharing scientific terms in the field of nature conservation with the goal of assisting different user communities with metadata compilation and information discovery. A multi-thesauri solution is proposed, based on a Common Th...

This paper presents two data models for storing multiple thesauri in a single integrated database to be used as an aid to searchers in multi-database searching, for the construction of conversion tables between thesauri, and as a tool for constructing and maintaining individual thesauri. The paper first describes the nature of thesaurus data and a relational data structure for such data, which ...

Thesaurus is used in many Information Retrieval (IR) applications such as data integration, data warehousing, semantic query processing and schema matching. Schema matching or mapping is one of the most important basic steps in data integration. It is the process of identifying the semantic correspondence or equivalent between two or more schemas. Considering the fact of the existence of many t...

Synonymous relationships among biomedical terms are extensively annotated within specialized terminologies, implying that synonymy is important for practical computational applications within this field. It remains unclear, however, whether text mining actually benefits from documented synonymy and whether existing biomedical thesauri provide adequate coverage of these linguistic relationships....

This research investigated the application of techniques successfully used in previous information retrieval research, to the more challenging area of medical informatics. It was performed on a biomedical document collection testbed, Ž . CANCERLIT, provided by the National Cancer Institute NCI , which contains information on all types of cancer therapy. The quality or usefulness of terms sugges...

In this paper building statistical language models for Persian language using a corpus and incorporating them in Persian continuous speech recognition (CSR) system are described. We used Persian Text Corpus for building the language models. First we preprocessed the texts of corpus by correcting the different orthography of words. Also, the number of POS tags was decreased by clustering POS tag...

Numerous studies have investigated the health problems reported by veterans of the Persian Gulf War, but important questions remain. Epidemiologic studies have consistently indicated that Gulf War veterans report unexplained symptoms at significantly higher rates than veteran comparison groups but that they have not experienced excess rates of disease-related mortality. Addressing unanswered qu...

The main concern of the present study was to compare Iranian monolingual and bilingual EFL students’ listening comprehension in terms of Latinized Persian subtitling of English movie to see whether there was a significant difference between monolinguals and bilinguals on immediate linguistic comprehension of the movie. Latinized Persian subtitling was representing Persian language in Latin scri...

Russian ( ), Persian ( ) and Siberian ( Acipenser gueldenstaedtii A. persicus A. ) sturgeons are closely related ‘Ponto-Caspian’ species. Investigation of baerii their population structure is an important problem, the solution of which determines measures for conservation of these species. According to previous studies, ‘baerii-like’ mitochondrial genotypes were found in the Caspian Sea among 3...
