This paper describes new thesaurus construction method in which class-based, small size thesauruses are constructed and merged as a whole based on domain classification system. This method has advantages in that 1) taxonomy construction complexity is reduced, 2) each classbased thesaurus can be reused in other domain thesaurus, and 3) term distribution per classes in target domain is easily ide...

With the development of big data, analyzing environmental benefits transportation systems by artificial intelligence has become a hot issue in recent years. The ground traffic changes can be overlooked from high-altitude perspective, using technology multi-temporal remote sensing change detection. We proposed novel unsupervised algorithm combining image transformation and deep learning method. ...

the purpose of the present study is to explore the impact of new coming terms on the structure of the recent editions thesauri compared to the previous ones. the case of this research is the 14th and 13th editions of eric thesaurus. the findings' indicate that the new terms affect the structure of thesaurus in terms of omission, change, or addition of the terms interrelations. but the high...

In this paper we investigate document ranking methods in thesaurus-based boolean retrieval systems, and propose a new thesaurus-based ranking algorithm called the Extended Relevance (E-Relevance) algorithm. The E-Relevance algorithm integrates the extended boolean model and the thesaurus-based relevance algorithm. Since the E-Relevance algorithm has all the desirable properties of the extended ...

Thesaurus is one of the most important components for information retrieval (IR) systems. A thesaurus provides a precise and controlled vocabulary that serves to coordinate document indexing and retrieval then it improves the retrieval effectiveness. However the major problem with the manual thesaurus is a laborintensive task and therefore also expensive to build and hard to update in timely ma...

This paper presents a method for automatically generating an association thesaurus from a text corpus, and demonstrates its application to information retrieval. The thesaurus generation method .consists of extracting tenns and co-occurrence data from a corpus and analyzing the correlation between terms statistically. A new method for disambiguating the structure of compound nouns, which is a k...

In this paper, the specific trait of Persian signatures is applied to signature verification. Efficient features, which can discriminate among Persian signatures, are investigated in this approach. Persian signatures, in comparison with other languages signatures, have more curvature and end in a specific style. An experiment has been designed to determine the function indicating the most robus...
