Guest Editors' introduction to the special issue: machine learning approaches to multimedia information retrieval

摘要

With today's ubiquitous presence of multimedia information in almost all IT-based applications, it is imperative to address the indexing and retrieval issues for managing the explosive growth of the multimedia data for such applications. Research in the area of Multimedia Information Retrieval (MIR) aims at dealing with these issues and focuses on the development of effective and efficient indexing and retrieval techniques for the multimedia data. Here, effectiveness refers to how well the retrieved multimedia information meets the users' expectation, and the efficiency addresses how responsive the underlying retrieval mechanisms are as queries are posed by the users.
