For its fourth edition SOS'2013 workshop proposes to highlight the multiple problems associated with the processing of data available on open sources (OS).
OS include all media freely accessible, free or paid, such as the Internet, public databases, journals, CD-ROMs, television and radio, etc. as opposed to closed sources whose access requires specific permissions. These OS provide huge amount of heterogeneous multimedia data (images, text, audio, video, etc.) requiring appropriate treatments to facilitate their exploitation. This workshop will focus on all these steps, starting from the discovery of available information sources, the collection and analysis of the collected data until the knowledge gathering and exploitation.
A specific interest will be on architectural choices selected for the implementation of applications using OS. Indeed, these applications usually attempt to reconcile several software components (COTS, open source software, ad hoc development, etc.) to make them work together in order to achieve a particular task. This represents a scientific and technical challenge for which researchers on implementation of processing chains to exploit these data can contribute. Emphasis will be placed on service-oriented architecture (SOA) and the use of Semantic Web technologies.
For this edition, SOS'2013 wants to put forward the recent challenges coming from the treatment of huge amount of data (called "Big data"). The new explosion of the Web size has led to an important need to adapt and optimize the whole information processing chain in order to manage these large amounts of data.
This workshop aims at bringing together researchers from academic and industrial worlds in order to obtain a representative panel of people tackling the different problems related to the topics listed below.
