Meiji University Web, Novelty and Genomic Track Experiments

To make computers understand a language, the most difficult problem is the ambiguity of the language. In Information Retrieval, a presence of multisense words causes retrieval performance decrement. According to the theory of meaning representation of use, proposed by Wittgenstein, the various meanings of a word can be represented by other words, and when a decentralized knowledge representatio...

Meiji University at ImageCLEF2010 Visual Concept Detection and Annotation Task

This paper describes the participation of the Web Science Laboratory of Meiji University in the ImageCLEF2010 photo annotation task. We devised a system that combines conceptual fuzzy sets with visual words that have become popular in the fields of image retrieval and recognition. The utility of the system was verified by comparing it with the ordinary Bag of Visual words technique. In addition...

Meiji University at ImageCLEF2008 Photo Retrieval Task: Evaluation of Image Retrieval Methods Integrating Different Media

This paper describes the participation of the Human Interface Laboratory of Meiji University in the ImageCLEF2008 photo retrieval task. We submitted eight retrieval runs taking two main approaches. The first approach combined Text-Based Image Retrieval (TBIR) and Context-Based Image Retrieval (CBIR). The second approach applied query expansion using conceptual fuzzy sets (CFS). A CFS is a metho...
