Special Issue on Semantic Web Dynamics

Recent years have witnessed the arrival of more and more semantically
annotated data and related ontologies in the Semantic Web. For example,
the linked data initiative has been very successful in making datasets
available online, with a total of about 5 billion triples all together  
far. While existing semantic tools and reasoning engines are year after
year getting better in dealing with time invariant domain of ontological
knowledge, supporting rapidly changing information has not yet attracted
sufficient attention.

There are more and more heterogeneous and/or dynamic data types being
created and which integration could lead to interesting applications and
models (e.g. sensor data streams, geospatial information and imagery,
financial transactions, news feeds, 3D models, engineering data,
information for policy intelligence etc.). Current Stream Database
Management Systems provide on the fly analysis of data streams, but they
suffer several limitations: they cannot handle heterogeneous data  
originating from a variety of already deployed sensors; they cannot
combine data streams with slowly evolving knowledge at query time; and
they cannot perform reasoning tasks. And in the area of reasoning, while
the problem of classical, time invariant domain of ontological knowledge
has been extensively studied, the task of reasoning with rapidly  
information has been mostly neglected and constitutes a new challenge.

Furthermore, ontologies, just like any structure holding knowledge and
information, need to be updated too: changes could be initiated  
because of
a change in the world being modeled; or by a change in the users’ needs
which would require a different conceptualization; or by the acquisition
of knowledge previously unknown, unclassified or otherwise  
unavailable; or
by the noticing of a design flaw in the original conceptualization. In  
these cases, the representation of knowledge in the ontology should be
modified so as to form a more accurate or adequate conceptualization of
the domain.

This general issue of Semantic Web Dynamics includes difficulties from
both practical and theoretical points of view, raising a variety of
research questions and development challenges, such as how to support  
ontology and data publishers in maintaining up-to-date, adequate
representations; how to detect the need for evolution and changes; how  
facilitate the integration of new, dynamic sources in existing datasets
and ontologies; how to validate and evaluate the impact of the changes  
semantic information; how to handle changes triggered from multiple
sources and collaborative updates; and how to keep track of (possibly
concurrent) versions of and ensure the delivery of up-to-date and valid
