Verbal and Semantic Processes in Social Tagging

January 28, 2015 Leave a comment

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.

Seitlinger, P., Ley, T., & Albert, D. (2015). Verbatim and Semantic Imitation in Indexing Resources on the Web: A fuzzy-trace account of social tagging. Applied Cognitive Psychology, 29(1), 32–48. doi:10.1002/acp.3067

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.

Kowald, D., Seitlinger, P., Kopeinik, S., Ley, T., & Trattner, C. (2015). Forgetting the Words but Remembering the Meaning: Modeling Forgetting in a Verbal and Semantic Tag Recommender. In M. Atzmueller, A. Chin, C. Scholz, & C. Trattner (Eds.), Mining, Modeling, and Recommending “Things” in Social Media (Vol. 8940, pp. 75–95). Heidelberg: Springer. doi:10.1007/978-3-319-14723-9

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.

EC-TEL and I-Know 2014 in Graz

This year I acted as a general chair of EC-TEL 2014 which took place in Graz. It was nice to return and it was even nicer that I-Know 2014 was collocated with EC-TEL so that we had loads of great talks and I met many old colleagues and friends.

The collocation of the conferences also meant we did have more keynoters than usually. Bernardo Huberman (from HP Labs, on the left) and Etienne Wenger (on the right) joined us for the conference reception.

I especially enjoyed Etienne Wenger’s opening keynote who gave us some nice tasks to work on during the conference.

All in all, it was again a great conference. I am looking forward to seeing all again next year!
