Description We analyze routing mechanisms of a self-organizing semantic overlay for content-based search in multimedia data. This overlay operates over any existing P2P network based on the metric space approach. In particular, we replace the previous design of routing mechanisms in Metric Semantic Overlay (MSO) with a new adaptive query-routing algorithm. An advantage of it lies in an automatic tuning of confusability of queries that is used to select peers during query evaluation. These improvements are experimentally evaluated on a real-life and synthetic dataset.
