Abstract: Distributed semantic stores can employ self-organization principles to improve their scalability. We present an implementation that uses ant colony optimization for clustering similar semantic information facilitating scalable retrieval. For the clustering mechanisms we use similarity measures that do not rely on access to a complete ontology. We describe a syntactical and a fingerprint-based similarity measure and discuss them regarding to expressiveness and computational effort. The results of an evaluation show that, with increasing volume of data and number of processes, the fingerprint-based measure performs much better than the syntactical one. We conclude with a discussion how to combine the advantages of the two measures and propose some technical enhancements improving the efficiency of the system.
