OntoBlog: Linking Ontology and Blogs

Semantic blogging attempts to enhance traditional blogging by using Semantic Web technologies. Blog entries are semantically enriched by metadata. However, authoring metadata is not easy for normal users. Currently semantic blogging only offers limited semantic capabilities. It is still difficult to navigate through semantically related entries, search and organize relevant blog entries. OntoBlog attempts to solve these issues by linking blogs to existing ontology maintained using available ontology management environment. OntoBlog is a prototype semantic blogging system which employs semi-automatic semantic annotation of blog entries using ontology instances. Blog entries are automatically mapped to related instances using language processing techniques. The rich structure of ontology with different semantic relations, enhanced by inference, can enable useful semantic capabilities. Semantic navigation allows users to navigate through each blog entry to semantically related blog entries. Semantic search can be employed in blogs. Semantic aggregation collects blog entries relevant to the topic of interest and organizes them meaningfully. A prototype for computer department domain ontology has been implemented.
