On September 1, I was a member of the Pragmatic Web track panel of the I-SEMANTICS 2010 conference in Graz, Austria, after having given the keynote earlier that day. The Pragmatic Web is a newly emerging field, still in the process of being defined. Its main focus is not Web technology per se, but the contexts and communities in which these resources are developed and used to accomplish goals, develop mutual understanding, and create and realize commitments. For background see the Pragmatic Web community site, and my blog posts Patterns for the Pragmatic Web and The Growth of the Pragmatic Web.
The Pragmatic Web should not be seen as separate from, but instead as building on and feeding into the Semantic Web, which concentrates on knowledge representation and reasoning approaches. One can try to formally represent “everything necessary” in a context but (1) this overformalization often kills the necessary human interpretation of any situated context and (2) still does not answer what relevant context factors are. Mainstream Semantic Web research does not deal with the subtleties of communities, goal setting and negotiation, human interaction, and myriad other context factors. For this, you need research perspectives different from those provided by the Semantic Web field itself. Of course, there is no precise dichotomy between the Semantic and the Pragmatic Web, instead there is a grey zone between the two fields, like the “Social Semantic Web”.
In the panel, we discussed the status and future of the Pragmatic Web. Other panel members included Alexandre Passant (DERI), Hans Weigand (Tilburg University), and Adrian Paschke (Freie Universität Berlin).
Alexandre covered the budding field of the Social Semantic Web, which examines how social interactions on the Web lead to the creation of explicit and semantically rich knowledge representations. Hans discussed another research area that is a major contributor to the Pragmatic Web, the Language/Action Perspective, as is its sibling Organisational Semiotics. Adrian focused on the Corporate Semantic Web, and the Pragmatic Agent Web, which represent some of the more applied research areas.
My own presentation was about what’s up with the Pragmatic Web as an area of research. I placed it in the Web 3.0 era we are entering, covered some of its fundamental questions and theories, and presented a socio-technical conversation context perspective that can be used to organize and position Pragmatic Web research (the framework is further explained in the paper and presentation of my invited talk.) I showed how the number of research publications addressing or referring to the Pragmatic Web is growing rapidly (with a small dip in last year’s number of publications). The high turnout at the panel discussion, especially given the competition of many high-quality parallel tracks, should also be a sign of the growing interest in the field. Finally, I positioned some contributing and related research fields shaping and being influenced by the Pragmatic Web. Core contributing fields in my view are Community Informatics, the Language/Action Perspective, Organisational Semiotics, Web 2.0/social media and the Semantic Web. See slide 7 of:
The discussion following the presentation, as well as many personal responses later, indicate that the Pragmatic Web as an area of research seems to be viable. One criticism is that much of the research is still very conceptual and needs to materialize much more into concrete applications and projects. This criticism is justified, but can be partially explained by the early stage the field is in and the still small number of researchers and organizations involved. However, there is also a more fundamental reason for this lack of applications: the Pragmatic Web studies context, and context by its very nature is extremely wide in scope and is always context of something else. Still, by fruitfully cooperating with more technology-driven and application-oriented R&D areas like the Social Semantic Web and Web 2.0, fundamental research insights about relevant contexts generated by the Pragmatic Web community should descend into the real world and become much more visible in the years to come.
