After pursuing a long tradition of study in Philosophy, the term “ontology” has become the new buzzword in computer science.  It is receiving special attention not only from an active community of researchers pertaining to many areas of informatics  but also from the industry, which is providing increasing budgets and investments to develop this technology and make it available in business as soon as possible. 
There is at least one main reason for this recognition: ontologies constitute the backbone of the Semantic Web, as they are responsible for providing context to pages, thus promising to make a relevant part of the Web contents understandable and processable by the software. However, there are some challenging obstacles that should be tackled to make ontologies wide-spread reputation shift from a promise to a daily used technology. For instance, heterogeneity and evaluation are two of these obstacles. 
Following the realization of the Brazilian "Workshop on Ontologies and their Applications" series (see for the first edition and for the second), we planned this Special Issue as a follow-up for the last edition of the workshop. With this Special Issue, we intend to enrich the discussion on how to enhance ontologies’ applicability, thus realizing this promising technology in general, but also in specific settings, such as e-business and e-commerce to name but a few. 

Topics of Interest:

Topics of interest include, but are not limited to:

Ontology Engineering
- methodologies
- capture and learning
- management

Semantic consistency
- foundational ontologies
- upper-level ontologies
- evaluation methods, applications and problems

Semantic Interoperability
- composition and modularity
- merging, mapping and alignment
- ontology language interoperability

Enhancement of ontology applicability 
- linguistic ontologies applied to text processing
- patterns of ontologies for specific applications 

Ontologies for Information Sharing 
- ontology-based information integration
- mediators and brokers 
- agents and ontologies

Ontology Applications
- Semantic Web 
- knowledge management
- e-commerce, e-government 
- e-learning and e-science
- information retrieval

Submission procedure:

We encourage the submission of high-quality papers based on entirely new work or surveys, both meeting the foci of the Special Issue. Papers must be written in English and may have a length from 20 to 30 pages, including tables, figures, and references. 

As for the format, papers must conform to the J.UCS style, formatted in PDF (preferred) or PostScript. It is recommended that authors use the J.UCS template files (see for formatting instructions) to minimize possible conflicts when preparing the camera ready. Word and Latex J.UCS style samplers are provided in

Papers should be submitted electronically only to one of the guest editors (see e-mail addresses below) up to the deadline (April 15,2007). Authors should not neglect that, together with the camera-ready version of the paper, a Copyright Transfer Statement (which can be downloaded from must be signed and sent/faxed by each author to Mrs Dana Kaiser, Manager of the J.UCS, via web ( or by fax (+43 316 873 5699).

Submitted papers will be peer-reviewed by three qualified reviewers/referees. Any other questions regarding papers submission must also be directed to the guest editors.

April     15 2007  - Submission due date
July       1 2007  - Notification of paper acceptance
September 15 2007  - Camera-ready paper due
October      2007  - Publication of the Special Issue on Ontologies & their Applications
