QwwwQ: Querying Wikipedia Without Writing Queries

摘要

Wikipedia contains a wealth of data, some of which somes in a structured form. There have been initiatives to extract such structured knowledge, incorporating it in RDF triples. This allows running queries against the body of knowledge. Unfortunately, writing such queries is an unfeasible task for nontechnical people, and even those who are familiar with the SPARQL language face the difficulty of not knowing the logical data schema. The problem has been attacked in many ways, mostly by attempting to provide user interfaces which make it possible to graphically navigate the see of RDF triples. We present an alternative user interface, which allows users to start from a Wikipedia page, and to simply express queries by saying "find me something like this, but with these properties having a value in the [A-B] range".
