Abstract

The need to assess the trustworthiness of a piece of information
has become a prevalent issue due to web vandalism and the openness
of platforms such as wikis. In this paper we introduce the notion
of contextual accountability: Holding the author of a given statement
accountable by deriving a path from the statement to the author’s credentials.
We present our own trust vector model as a combination of the
assessment of these credentials covering two aspects; knowledgeability
and social acceptance. This model is put to the test using two datasets
and the results are presented and discussed.
