WiGiPedia: Visual Editing of Semantic Data in Wikipedia

INTRODUCTION Wikipedia is emerging as the dominant global knowledge repository. Recently, large numbers of Wikipedia users have collaborated to produce more structured information in the online encyclopedia. For example, the information found in tables, categories and infoboxes. Infoboxes contain key-value pairs, manually appended to articles based on the unstructured text therein. The wiki contains some structured information which can be crawled by DBpedia [2], which attempts to organize wiki data into into a database of subject-predicate-object triples. By leveraging this data we generate an interface, which we call WiGipedia, embedded on every Wiki article as an interactive graph visualization where entities represent articles, categories and relational entities, with typed edges between them. This intelligent web interface is designed to simplify the elicitation of semantically structured information in Wikipedia (Figure 1). Our motivation is to both inform the user of interesting contextual information pertaining to the current article, and to provide a simple way to introduce and/or repair semantic relations between wiki articles. User actions result in improved accuracy and consistency of structured data spread across multiple articles. WiGipedia provides users with an intuitive interface that allows single-click edits without knowledge of the Wiki markup language, templates, etc. An online demo of the interface can be found at www.wigipediaonline.com.
