The Semantic Foundations of Image Databases
نویسنده
چکیده
All searches in a database are semantic in nature: a user searches something based on a certain meaning that the results will share. This model, derived from traditional databases has been extended to image databases, but insufficient attention has been paid to the characteristics of signification in images and to the technical challenges and opportunities that they generate. This paper presents an analysis of the relation between images and their meaning and argues that in image databases the process of signification is no longer unique, but it divides in at least three largely independently modalities. Each one of these modalities will require a different definition of the term “query” and, consequently, a different approach to query specification and processing, as well as to image representation. keywords: image databases, image semantics, query modalities, query processing.

متن کاملMeaningfulness of Religious Language in the Light of Conceptual Metaphorical Use of Image Schema: A Cognitive Semantic Approach
According to modern religious studies, religions are rooted in certain metaphorical representations, so they are metaphorical in nature.
