Description of the Workshop

One of the key challenges in making the static Web and dynamic applications such as Web services more intelligent is to introduce some form of automated reasoning. For example, the Semantic Web promises machine-readable semantics and a machine-processable Web through ontology-based annotation of static data on the Web and Web-based dynamic applications and services. Such annotation facilitates querying and aggregating data sources on the Web in a unified manner, as well as automating discovery, selection and composition of services. Reasoning technologies for services and data on the Web have typically focused on Description Logic (e.g., OWL DL) and Rule-based (RIF, RuleML) approaches and languages. In this workshop we focus on the latter with a particular focus on Logic Programming as a viable candidate paradigm for enabling intelligent and declarative Web applications.

Many workshops and conferences that are dedicated to the Web arena deal mostly with generic topics and bring together people from a variety of research fields with different understandings of the topic. The plethora of these workshops and conferences make it hard to keep track of the various approaches of a particular technology such as Logic Programming in our case. We deliberately take a narrower focus to advance the application of LP as a paradigm for declarative knowledge representation and reasoning to the Web and Web services. Towards this aim we bring together researchers working on applications of LP to (Semantic) Web and Web services, as well as LP-based foundations for Semantic Web and Web service languages. ALPSWS 2008 is the 3rd workshop in its series, still following its original goals:


Possible topics include (but are not limited to):


We invite two forms of submission to this workshop: full papers and short papers. Full papers shall be up to 14 pages length, short papers 6 pages which could include position papers, system descriptions or preliminary work. The workshop content will be made available in separate workshop proceedings. Please use the Springer LNCS format for the papers. Submitted papers will be reviewed by at least two members of the program committee. Papers must be submitted electronically in PDF format. For paper submission we use the EasyChair conference management system:
