Metadata miner assisted integrated information retrieval for argo ocean data

Argo project is an international ocean-observatory project that has a global array of 3,000 more free-drifting profiling floats. Argo data is a large collection of data files. To retrieve Argo data from the large database is a complicated work even if the Argo database has a metadata file per day for helping user to inquire the target files. This paper proposes a metadata miner (MM) approach to assist user program to inquire the target files quickly. In addition, we also propose an integrated information retrieval framework that based on mediator/wrapper approach to smoothly tie the MM. According to the performance evaluation, it shows that the MM approach has a significant performance enhancement in finding the target file.
