Advantages of Semantic Web Technologies Usage in the Multimedia Annotation and Retrieval

During the last few years, there was a large increase in various forms of multimedia content on the Web, which presents a growing problem for the further use and retrieval of such content. In parallel, with the increase of multimedia content on the Web existing multimedia metadata standards were improved and new standards have been developed. To facilitate the use of multimedia content on the Web, that content is assigned a metadata that describes it. Manually annotation is time- consuming and expensive process. Besides, annotations can be created by different people such as authors, editors, publishers or the end users, which represents a problem, because there may be different interpretations of those annotations. The main disadvantage of such annotations is the lack of well-defined syntax and semantics which is why computers in most cases can hardly process such information. Using Semantic Web technologies such as XML, RDF and ontologies is recommended for creating new and enriching existing annotations due to a large number of multimedia metadata formats and standards and their incompatibility.
