Salient Feature Selection for Visual Concept Learning

Image classification could be treated as an effective solution to enable keyword-based semantic image retrieval. In this paper, we propose a novel image classification framework by learning semantic concepts of image categories. To choose representative features for an image category and meanwhile reduce noisy features, a three-step salient feature selection strategy is proposed. In the feature...

Concept-Based Lexical Selection

We present a concept-based approach to the problem of lexical selection which allows us to deal precisely with lexicalization gaps or mismatches in mapping from a source language into a target language. We adopt a linguistically motivated scheme that makes use of a decompositional representation which can be classified in terms of a KR ontology. A main contribution of our representation scheme ...
