Fourth edition of the workshop
"Services and Open Sources" - SOS’2013

January 29th, 2013 at Toulouse (France)

Co-located with EGC’2013


Workshop presentation

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.


Workshop topics

  • Identification and automatic discovery of information sources,
  • Access and collection of information from open sources (web, social networks, RSS feeds and others),
  • Classification and filtering of information of interest,
  • Information extraction from unstructured text and/or using specific vocabularies (blogs, texting, forums),
  • Information extraction from large corpus of multimedia data (text, image, video, audio),
  • Opinion and sentiment analysis from social media (social networks, weblogs, forums),
  • Modeling and gathering of knowledge extracted from open sources (ontologies, semantic annotations),
  • Exploitation of knowledge extracted from open sources: reasoning, decision support, visualization,
  • Detection of weak signals,
  • Open sources quotation and assessment,
  • Quotation of information extracted from open sources,
  • Inference mechanisms, mining and link validation between data,
  • Platforms for the integration of heterogeneous processing services: service interoperability, semantic orchestration,
  • Strategic or economic watch applications from open sources,
  • Open sources intelligence applications (OSINT),
  • "Big data"-oriented applications.
