AbstractIn consumer electronic markets, rating mechanisms are important facilitators of trust between market participants. This technical report investigates whether source credibility theory can support the evaluation of bidders in Architecture/Engineering/Construction (AEC) electronic market places. In contrast to consumer electronic marketplaces, the raters in AEC communities are skilled and connected, necessitating a reputation mechanism to account for the relationship between the user and the rater. To solve this problem, TrustBuilder, a prototype rating tool, facilitates information between peer industry practioners by calculating a weighted rating based on source credibility theory. An experiment shows that AEC industry practitioners who evaluate bidding subcontractors trusted the information provided by TrustBuilder significantly more than the information from a standard unweighted rating tool.
