- 46 abstract "As scalability and flexibility has become a critical concern in information management system, self-organizing network attracts attention from both research and industrial communities. This work proposes a semi-structured semantic overlay for information retrieval in self-organizing network. With the assumption that each node in the network has autonomy to its resource, we organize the nodes into a semantic overlay hosting topically discriminative communities. For information retrieval within each community, unstructured routing approach is employed for the sake of scalability and flexibility; While for joining new nodes and routing queries to a remote community, a structured mechanism is introduced to save traffic and time. Different from the semantic overlay networks in the literature, our proposal has three contributions: 1)we propose a subspace-clustering approach to explore refined semantic relationship between nodes; 2)we introduce topic-based indexing to form the semantic overlay; 3) we design a dynamic scaling approach to adjust community’s enlarging or shrinking.".
