|The World Wide Web contains huge amounts of information created by many different organizations, communities and individuals for many different reasons. Most of the Web's content today is designed for humans to read, not for computer programs to manipulate it meaningfully. The solution how to develop machine understandable web is to use metadata to describe the data contained on the Web. This new approach is called Semantic Web. To understand semantic meaning metadata are not enough. We need to know applicable ontologies, which define relationships between several concepts. We may see the sense of ontologies as a knowledge models or an abstract description of certain part of knowledge system, which are relatively independent on a final representation and implementation of knowledge. It is essential, that this models are shareable by several proceses (etc. software agents) in single application and reusable for different applications, which can be separated by time and space. Ontologies are not just static pasive files of valid relationships, but are also knowledge bases among them it is possible to make machine inferences. As Semantic Web expands it gives us more space for research of possibilities of using ontologies in information systems with the help of inteligent agents and semantic web services.|
