Magdalena Litwin · 2003
In a world of infoglut finding requested information is a difficult task. Main reason of that is the lack of semantic structure in most of web applications. Popular search engines and other services enabling information retrieval utilize a simple textual search without any semantic layer. Topic Maps ISO standard provide a solution to this problem. Its paradigm is based on representing knowledge in the shape of concepts, relation among them and resources. The paper contains some detailed information on the topic maps paradigm. An application of enzymes knowledge database – the e-enzyme system is presented as an authors’ example of the topic map. Some problems in developing of topic maps are pointed out: manual ontology building, visualization, lack of querying standard and methodology for topic maps design.
