What happens when people tag resources on the Web? Do they just mindlessly copy other people’s tags, or do they generate tags from a deliberate and meaningful activity? In fact they do both.

In this publication, we have invented a method which allows us to look into people’s heads when they tag. And we don’t need an fMRI Scanner to do it.
And in another recent publication we have shown that a recommender service that is based on both verbal and semantic processing actually performs better than many alternative approaches.

A very nice interdisciplinary work that has lead to high level publications in cognitive psychology (ACP), HCI (CHI) and Knowledge Management (CIKM). The main work was done in the MERITS project by Paul Seitlinger.
Together with colleagues at the TU Graz, Dietrich Albert and my former PhD Student Paul Seitlinger, I was recently successful in applying for an Austrian Science Fund (FWF) project. The project will continue a research route that I have been pursuing already for a number of years. We will be researching cognitive processes involved when people use collaborative tagging systems. On the one hand, this research allows to uncover some of the thinking processes involved when we use social web environments, and on the other hand it allows for exciting technological advances, such as intelligent recommenders.
Implicit and Explicit Memory in Collaborative Tagging
Supported by the Austrian Science Fund (FWF), Austria’s central funding organization for basic research, this two-year project starts on 1st October 2013. This is a cooperation between the Knowledge Technologies Institute at TU Graz, Austria (Prof. Dietrich Albert), and the Centre for Educational Technology at Tallinn University, Estonia (Prof. Tobias Ley).
By means of mathematical models of human memory and several experiments, the project examines cognitive processes involved during the assignment of labels (so called tags) to Web resources, such as bookmarks and photos. A model of a user’s categorization and subsequent labeling of a Web resource will be formalized. This model will then be applied in the design of an intelligent algorithm recommending user specific tags as well as Web resources.
