Semantics-based retrieval by content
Alberto Del Bimbo · 2002
For the practical use of visual information retrieval systems, access to visual data must be provided so as to bridge the semantic gap between the system and users. Although the problem seems to face only the level of representation, indeed the user interface and feature organization play equally essential roles in obtaining effective retrieval systems. Semiotics, which is concerned with the description of conditions for the production of sense and of the way in which it is received by humans appears as the formal background to casting the development of retrieval by semantic information.
