5th International USEWOD Workshop: Using the Web in the Age of Data

People argue that we have moved into an age of several Webs - the Web of Data, the Web of Documents, the Semantic Web, the Deep Web, the Dark Web, and many more. However, this is an illusion - there exists only the one #WebWeHave, and it is under our control to make it be the #WebWeWant. To emphasize this, the key theme of the 5th edition of the USEWOD workshop is about using the Web in the age of data, bringing together two spaces again that have recently been investigated separately: classical Web usage mining and Web usage mining in the context of the Web of Data.

The purpose of the USEWOD workshop series has been to create and maintain a forum for researchers to investigate the synergy between the Web of Data and Web usage mining. This required the analysis of semantic data usage. With the next edition we respond to the fact that publishing and consuming raw data on the Web is an established paradigm today and turn the USEWOD workshop into a forum to discuss more general questions about the usage of the Web. How will the analysis of Web usage benefit from the possibility to blend the classical log with the structure sourcing from Linked Data? Can the progress that has been made on (Read/Write) Linked Data change the way we interact with the Web and what does that mean for the usage analysis capabilities we have at hand today?

Title: Rethinking Online SPARQL Querying to Support Incremental Result Visualization

Abstract: To reduce user-perceived response time many interactive Web applications visualize information in a dynamic, incremental manner. Such an incremental presentation can be particularly effective for cases in which the underlying data processing systems are not capable of completely answering the users' information needs instantaneously. An example of such systems are systems that support live querying of the Web of Data, in which case query execution times of several seconds, or even minutes, are an inherent consequence of these systems' ability to guarantee up-to-date results. However, support for an incremental result visualization has not received much attention in existing work on such systems. Therefore, the goal of this talk is to discuss approaches that enable query systems for the Web of Data to return query  results incrementally.

Bio: Olaf received a PhD in Computer Science from the Humboldt-Universität zu Berlin. Thereafter, he worked as a postdoctoral research fellow at the Cheriton School of Computer Science at the University of Waterloo. Olaf's research interests are in different aspects of Web data management, such as Web query processing, query languages for Web queries, Web data provenance and quality, RDF databases and the Semantic Web, as well as graph databases. Olaf is leader or contributor of several open source projects, most notably SQUIN, which is a novel query processing system for Linked Data on the Web. Olaf co-organized international research workshops, served on multiple program committees, and participated as an invited expert in the provenance incubator group and the provenance working group of the World Wide Web Consortium.
