Abstract

This exploratory study contributes to research on relevance assessment by specifying criteria that are used in the judgment of information quality and credibility in Internet discussion forums. To this end, 4,739 messages posted to 160 Finnish discussion threads were analyzed. Of the messages, 20.5% contained explicit judgments of the quality of information and credibility in other messages. In the judgments, the forum participants employed both positive criteria such as validity of information and negative criteria such as dishonesty in argumentation. In the evaluation of the quality of the message's information content, the most frequently used criteria pertained to the usefulness, correctness, and specificity of information. In the judgment of information credibility, the main criteria included the reputation, expertise, and honesty of the author of the message. Since Internet discussion forums tend to emphasize the role of disputational discourse questioning rather than accepting the views presented by others, mainly negative criteria were used in the judgments. The generality of our claims is limited because we chose forums that focused on sensitive and value-laden topics; future work could explore credibility and quality judgment in other forums and forumlike venues such as question and answer sites as well as exploring how quality and credibility judgments interact with other aspects of forum use.

Abstract

As a result of the Internet, electronic networks occupy a more visible place in everyday life. Until the early nineties, the use of electronic networks was limited to a rather small number of people working in enterprises and universities. Since then, the networks have become more accessible for other citizens. Currently at least 60-70 million people all over the world are estimated to use the Internet (Gaines et al., 1997: 990). In 2000, the number of WWW users alone is expected to reach 160 million (Aldridge & Darwood 1997: 283). The rapid growth of network use has given rise to a lot of research needs. For example, what are the main purposes of network use and to what extent may the Internet replace other channels in information seeking? Thus far, the utilization of networks has been mainly surveyed in the USA but, in recent years issues of use have also attracted increasing attention in Western Europe. This study is a continuation of a research project focusing on the ways in which citizens seek information in the context of everyday life (see Savolainen 1995). An attempt is made to analyze how citizens utilize the electronic networks, primarily for non-work purposes. This paper communicates part of an empirical study; a detailed report is available in Finnish (Savolainen 1998b).
