The OWLS-MX matchmaker selects OWL-S 1.1 services that are relevant to a given service request by means of logic-based matching complemented with syntactic similarity measurement. In this paper, we summarize the results of our experimental evaluation of the retrieval performance of OWLS-MX in terms of its false positives and false negatives using the service retrieval test collection OWLS-TC 2.1. Based on the analysis of false-positives and false-negatives of OWLS-MX, we implemented a matchmaker OWLS-MX2 with improved precision in average
