The Domain Restriction Hypothesis: Relating Term Similarity and Semantic Consistency

A Relative Structure Similarity Method For Multiple Ontologies Alignment

Knowledge in domain is expressed with the help of ontology which is scattered all over its space. Using ontology gives a share in increasing precision. Different ontologies may represent the same domain, thus includes different terms that equivalently refer to the same meaning and vice versa. This results in different structures for ontologies. That's why it is necessary to relate concepts and ...

A Comparative Study of Ontology Based Term Similarity Measures on PubMed Document Clustering

Recent research shows that ontology as background knowledge can improve document clustering quality with its concept hierarchy knowledge. Previous studies take term semantic similarity as an important measure to incorporate domain knowledge into clustering process such as clustering initialization and term re-weighting. However, not many studies have been focused on how different types of term ...

Confidence Measure Based on Context Consistency Using Word Occurrence Probability and Topic Adaptation for Spoken Term Detection

In this paper, we propose a novel confidence measure to improve the performance of spoken term detection (STD). The proposed confidence measure is based on the context consistency between a hypothesized word and its context in a word lattice. The main contribution of this paper is to compute the context consistency by considering the uncertainty in the results of speech recognition and the effe...

Semantic-Based Image Retrial in the VQ Compressed Domain using Image Annotation Statistical Models

A Comparative and Contrastive Study on the Meaning Extension of Color Terms in Persian and English

We deal with a wide range of colors in our daily life. They are such ubiquitous phenomena that is hard and next to impossible to imagine even a single entity (be it an object, place, living creature, etc) devoid of them. They are like death and tax which nobody can dispense with. This omnipresence of colors around us has also made its way through abstract and less tangible entities via the inte...
