Web Pragmatics: Semantic Web plus Context-Awareness Prof. Dr. Kurt Englmeier

2 Semantic Web & Web Pragmatics Semantic Web is about discovery and presentation of meaning captured within and across data. Web Pragmatics is about the inclusion of the context of human actors. Whatever data mean to their human users depends on the context where they are understood and produced. Web Pragmatics consider the communicative act in interaction.

3 Prof. Dr. Kurt Englmeier Co-existence of natural language and process management Web pragmatics takes modelling of computational behaviour to the specifics of the user’s tasks, language, culture, skills and organisational environment. Ontological perspective … Language-Action Perspective in the context of web mining: the human actor is the key designer of web mining processes. …

4 Prof. Dr. Kurt Englmeier Human actor as key designer Natural language provides a natural way to human actors to express behaviour and context of an application (web mining, for instance). Objective: human actors are the designers of their web mining processes (without resorting to IT-personnel).

5 Prof. Dr. Kurt Englmeier The role of controlled vocabularies and transactional grammar Controlled vocabularies comprise the key expressions of the human actor’s knowledge and working environment. Controlled vocabularies and a basic grammar serve to describe the respective language context that can also be interpreted by machines. Basic grammar appears in description patterns for transactions and helps to identify production acts (P- Acts) and coordination acts (C-Acts). From these acts result P-Facts and C-Facts.

6 Prof. Dr. Kurt Englmeier Storybooks for process management C-Act declare C-Act P-Act C-Act promise C-Act declare

7 Prof. Dr. Kurt Englmeier Translating natural language instructions: Retrieval of service descriptions and composition of related services

8 Prof. Dr. Kurt Englmeier Considering the process context

9 Prof. Dr. Kurt Englmeier Generic process descriptions They ensure the application of a method within the correct context of the application logic
