WEGA (Web Genre Analysis) is a technology for tagging Web search results with genre information. For each snippet in a search engine result list WEGA analyzes the type, purpose, or target group (= genre) of the underlying document, and labels the snippet as <discussion page>, <article>, <online shop>, <download site>, <private homepage>, <commercial homepage>, or <help site>. These genre classes were derived from user studies, and we have developed tailored document models for their classification. Since genre information is generally accepted as positive or negative filtering criterion, genre tagging simplifies finding the relevant results. [video]
