The real challenge for Semantic Web technologies and ontologies lies in the adoption; although the need for this disruptive technology is clear, it has not yet been fully adopted by the mainstream. Ontologies: where, what for, how, when and why? Ontologies are being used in several applications, but is ontology engineering a mature discipline? Not only are we interested in practical realizations of the Semantic Web, but also in visions of technology that illustrate how SW technology and ontologies could change our experience of the Web.

Questions and issues addressed by OCAS

  • How are SW technologies and Ontologies being adopted by mainstream?
  • Experience reports of the introduction of SW technologies and ontologies in corporate and government environments
  • Once introduced in an environment, how do SW and ontology-based applications evolve?
  • Ontologies in manufacturing and production chains
  • Ontologies supporting CAD interoperability and feature extraction; towards smart CAD environments
  • How could RDF(a) and ontologies be used to represent the knowledge encoded in scientific documents and in general-interest media publications?
  • What ontologies do we need for representing structural elements in a document?
  • How can we capture the semantics of rhetorical structures in scholarly communication, and of hypotheses and scientific evidence?
  • What does a network of truly interconnected documents look like? How could interoperability across documents be enabled?
  • Are decision support systems in the biomedical domain using ontologies? How?
  • How are biomedical ontologies logically formalizing the rich set of lexical definitions gathered? How are these ontologies going beyond controlled vocabularies?
  • Practical cases of successful and unsuccessful application of ontologies and SW technologies in application domains such as: financial, biomedical, e-business, engineering, law enforcement, document management, e-government, legislative systems.

We would also like to have visionary papers addressing issues such as:

  • Semantic Web + Ontologies + Ubiquitous Computing + Folksonomies =Visions of the future, how can technology make us look smart?
  • Conceptualism vs Realism, how is this related to Ontology Engineering? How is this related to the realization of the Semantic Web?
  • How are Semantic Web technologies and Ontologies shaping the intelligent layer of the Web?

OCAS Challenge

OCAS can be summarized in a simple sentence, “Ontologies and Semantic Web technology come of age; how is the Semantic Web changing our experience of the Web?” Moving beyond theoretical frameworks and heading towards a significant impact in end user experience is at the core of OCAS. The overall objective of the challenge is to illustrate how ontologies and SW technologies are delivering novel user experiences.


  • First place: US$ 2000
  • Second place: US$ 1000
  • Three third prizes of $500 each

Selected projects will be funded through implementation by Protech Solutions Inc.

Projects are to focus on innovative uses of HPC and data mining in semantic technologies for HealthCare, Medical Informatics and Computer Security. Projects with high relevance to social networking, low-tech environments, and third-world countries are encouraged.

Those participating in the challenge should provide a three-page manuscript describing their software; from the manuscript it should be clear for judges:

  • Software availability: judges and general public should be able to access the software. In most cases this means that the software, ontologies and/or infrastructure is freely accessible -free software is not compulsory.
  • Semantic Web technology: how is this application making use of semantic web technology? How is this application making use of existing infrastructure? Data sources being used, etc.
  • How is it delivering new layers of functionality based on semantic data sources (linked data, RDF stores, ontologies, etc).
  • How is it delivering an intelligent interconnected experience to the end user?
  • What is the added value?
  • How is the Interconnectedness of semantic data sets being delivered to the end user?
  • How are intelligence and interconnectivity being supported by the software or infrastructure?
  • Does the software or infrastructure represent a fundamental change for the domain rather than just an incremental improvement or just one of many added new features?

We would like to have applications from all domains. The GC is not limited to web based applications, mobile platforms for devices like iPAD, iphone, Galaxy, XOOM, HTC, etc are also encouraged. Authors submitting to other Challenges, workshops and conferences are welcome to also submit their work to the OCAS challenge.

For those who require high performance computing facilities, our sponsor, http://protechsolutions.com/, will make them available free of charge.

Submission should be via Easychair

All papers submitted for the OCAS Challenge should be formatted according to the LNCS format.
