DESCRIPTION

EvoDyn builds on the success of the previous editions of the Ontology Dynamics workshop formerly known as IWOD (organised as a part of the ESWC'07, ISWC'08, ISWC'09 and ISWC'10 conferences). EvoDyn continues in the tradition of IWOD in being the core annual event to discuss advances in the broad area of ontology dynamics, and to track recent work directly or indirectly related to the problem of evolving ontologies. This year, however, the scope of the workshop is broadened by a special focus on the knowledge evolution. As ontologies are formal representations of knowledge, the study of their dynamics is an inherent part of investigating the knowledge evolution phenomena, yet it is only one of many relevant aspects this workshop aims to cover in an integral manner.

In particular, the workshop focuses on analysis of trends and change in formal descriptions (i.e., ontologies), but also in associated raw sources of knowledge (scientific publications, unstructured or semi-structured web content, traditional data stores, e-mail or on-line discussion threads, etc.). We are especially interested in research targeted on various states of knowledge evolution, such as (a) conflicts, (b) consolidation, (c) discovery, (d) paradigm shifts, and (e) breakthroughs. One crucial objective of better understanding these different states may be to study directly the underlying causes and dynamics needed to generate discoveries and breakthroughs. We will only be able to facilitate and possibly also generate such desirable situations if we can understand the process of how knowledge evolves. The process of how knowledge in a field grows and changes, crystallizes, and fractures are all areas of interest of this workshop. The same holds for related novel applied technologies, such as:
  * Tools for tracking the progress of knowledge from latent ideas, through hypotheses to well-supported facts and/or claims;

  * Methods for identifying what are the crucial fulcrum-points where a particular field may blossom or fail;
  * Methodologies and supporting tools for identification and reinforcement of emerging promising trends in various academic and/or industrial domains;
  * Platforms facilitating interconnection and cross-fertilization of related endeavors in isolated disciplines.

GOALS

We would like to trigger a comprehensive and coherent approach to studying (and ultimately facilitating) the process of knowledge evolution by bringing together researchers and practitioners from the following fields:
  * Data mining and knowledge discovery in dynamic resources.
  * Ontology dynamics and versioning.
  * Trend analysis (in multiple applications, including internet search, corpus evaluation, etc.).
  * Natural Language Processing (evolution of terminology, language use, semantics).
  * Knowledge Representation (temporal ontologies, temporal logics, belief revision, etc.)
  * Discourse Analysis and Philosophy of Science (the definition and understanding of what particular phases of the knowledge evolution are, and how can we delimit, identify or even trigger them)
  * Relevant application domains (such as Biomedical informatics, Neuroinformatics, and Biomedicine in general, but also domains like Internet Search, Business Analytics, Legal Studies or Digital Humanities)

We think that only after cross-fertilization of these different perspectives we can achieve a truly representative and coordinated research agenda covering all different facets of the knowledge evolution within specific, well-defined concrete examples from a wide variety of fields. The ultimate importance of such an effort lies, of course, in better understanding of what knowledge evolution actually is and how we can make the whole process more efficient in various application areas. Given both the potential impact of scientific discovery and the difficulties inherent in understanding how to create it, we feel that focusing on the topic of knowledge evolution is much desired and could conceivably encourage identification and tackling of grand challenges in the area of scientific discovery.

Ideally, we would like to see the practitioners and researchers actively network and collaborate in order to define and understand the most relevant and important lines of research pertinent to the underlying goal of understanding and enabling the processes of discovery, paradigm shift and breakthrough. This is going to be achieved by active engagement of the workshop organisers, authors and participants beyond mere paper presentation and discussion sessions. Before the workshop itself, we will identify a set of general grand challenges, partly based on the submissions received. These will serve as a guideline for an interactive discussion session that will be a part of the workshop agenda. The interactive session is supposed to wrap up the workshop with a concrete list of research questions and use cases most pertinent to knowledge evolution and ontology dynamics, accompanied with a tentative plan of related collaborative research and application development efforts.
