Knowledge Resource Development for Identifying Matching Image Descriptions
english

Alicia Sagae, Scott E. Fahlman
2013 Proceedings of the International Conference on Knowledge Engineering and Ontology Development  
knowledge resources contribute to the performance of many current systems for textual inference tasks (QA, textual entailment, summarization, retrieval, and others).  ...  This paper describes the incremental, task-driven development of an ontology that provides features to a system that retrieves images based on their textual descriptions.  ...  As a result, MIRFLICKR has been used for image annotation and retrieval by visual example, but is not sufficient for testing retrieval by phrasal description.  ...
