Accessing Linked Data with Collustra

Printer-friendly version


Last semester TWC Ph.D student Evan Patton presented semantic web support for the MIT AppInventor platform that enables Android developers to use linked data to power applications[1]. However, application of this work revolves around proficient understanding and ability to construct SPARQL queries, which is a challenge for the target audience of the AppInventor. This summer Evan began work with graduate students at MIT's Decentralized Information Group (DIG) to develop a query-by-example inspired HTML5 application, Collustra[2], for constructing bottom-up SPARQL queries given a SPARQL endpoint. Evan and the MIT team make use of the SPARQL Inference Notation (SPIN) [3] to represent SPARQL queries in RDF so that queries can be stored in an endpoint with the goal of being able to index and search them. This also enables queries to be accessed from within AppInventor to ease linked data app development.

On Wednesday Evan will demonstrate an alpha version of the software and provide a road map in the first portion of the talk. For the remainder of the time there will be a group discussion on how tools such as Collustra could be used within Tetherless World and elsewhere to encourage access to linked data and what improvements are necessary to foster this growth. Students who are new to the lab or interested in learning SPARQL will benefit most from this talk.

Description: Web Science is the study of the World Wide Web and its impact on both society and technology, positioning the Web as an object of scientific study unto itself. Web Science recognizes the Web as a transformational, disruptive technology; its practitioners study the Web, its components, facets and characteristics. Ultimately, Web Science is about understanding the Web and anticipating how it might evolve in the future.
