Semantic wiki support for intelligence work

The semantic web is an extension of the World Wide Web where the semantics of information is defined. The formally defined semantics make it possible for machines to get a better understanding of how the information can be used, and what links between documents represent. By combining the wiki concept, a web site where anyone is able to create and edit content using a web browser, with ideas from the semantic web, something called a semantic wiki can be created. Incorporating ideas from the semantic web may improve the information structure, which makes it easier for a user to find relevant information and to find out how things relate to each other. This thesis presents a semantic wiki prototype and describes how a semantic wiki could be used to support intelligence work with focus on gaining situation understanding. An experimental exercise showed that articles with dynamic content based on semantic search questions is a powerful new feature. The experiment also revealed that a semantic wiki is of no more use than an ordinary wiki unless the content is annotated with semantic information, which is a time-consuming activity. Future work includes investigating how the tagging process can be improved and automated. Semantisk wiki som stöd vid underrättelsearbete
