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.

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.

Paper accepted at CHI 2012

A paper by my PhD student (Paul Seitlinger) and myself was accepted for this years CHI conference in Austin, Texas.

Seitlinger, P., & Ley, T. (2012). Implicit Imitation in Social Tagging: Familiarity and Semantic Reconstruction. Proceedings of ACM SIGCHI Conference on Human Factors in Computing Systems (CHI 2012), Mai 02-05, Austin, Texas (in press). New York: ACM Press.

In the paper we examine how people imitate tags in a social tagging environment. Rather than just looking at the tags people use, we employed a multinomial model together with a specific experimental paradigm to study the underlying memory processes at play.
