Extracting and Re-using Structured Data from Wikis

[摘要] This report investigates simplifying the creation of structured data for use in Semantic Web applications. In the first phase of work, a prototype is created that extracts structured data on companies and unstructured data on acquisitions from Wikipedia. It then reuses this information in a data browser that can provide faceted, map and timeline views. In the second phase, we investigate more generic approaches for extracting structured data and related schema information from Wikipedia. We use this information to create user interfaces that simplify the creation of structured data about related topics. This demonstrates that it is possible to simplify the creation and re-use of structured data in ways that benefit users. 21 Pages
