Project

Use of Collective Knowledge through Social Tagging

Working group Knowledge Construction Lab
Duration 07/2007–06/2017
Funding budget resources IWM
Project description

How can social tagging support learning and the joint construction of knowledge? This project tries to answer these questions with experimental studies about the reception of tags and tag clouds.

 

Social tagging is the activity of individually annotating and classifying content (e.g., bookmarks, scientific articles, pictures or products) with keywords (tags). Individually given tags can be aggregated into tag clouds. In this way tag clouds can represent the conceptual knowledge of a community.

In the project we research if people use this collective knowledge when searching for information and if they gain new knowledge for themselves. First studies show that tag clouds can even reduce misconception of users.

 

The theoretical base of the studies is the Co-Evolution Model (Cress & Kimmerle, 2008) as well as the Information Foraging Theory (Pirolli & Card, 1999). We are especially interested in the influence of person characteristics (e.g., prior knowledge, epistemological beliefs, openness) and characteristics of the tag cloud (trustworthiness of the source.
