Abstract: A trustworthy Web service recommendation method was presented based on open network environment and collaborative filtering. First, a set of Web services with same or similar functions was searched according to user’s requirement. Second, the collection of users that have similar preferences for the target user was computed based on their common evaluations, and the recommendable user set for each candidate service was obtained, then the recommendation degree for each service was computed using its similarity, and the candidate services was sorted according to the recommendation degree to the target user. The experimental results showed that the referral effect increased with the increase in the number of user evaluations.

Key words: Web service, trustworthy service, service recommendation, collaborative filtering, service ranking
