Abstract

Traditionally Semantic Web applications either included a web crawler or relied on external services to gain access to the Web of Data. Recent e orts, have enabled applications to query the entire Semantic Web for up-to-date results. Such approaches are based on either centralized indexing of seman- tically annotated meta data or link traversal and URI dereferencing as in the case of Linked Open Data. They pose a number of limiting assumptions, thus breaking the openness principle of the Web. In this demo we present a novel technique called Avalanche,designed to allow a data surfer to query the Seman- tic Web transparently.The technique makes no prior assumptions about data distribution.Speci cally, Avalanche can perform “live” queries over the Web of Data. First, it gets on-line statistical information about the data distribution,as well as bandwidth availability. Then, it plans and executes the query in a distributed manner trying to quickly provide rst answers.
