A comprehensive multimedia material library system with semantic expansion retrieval

It is widely recognized that multimedia data and related technologies have being a growing part of our lives. This leads to a demand for systems and tools that can satisfy the more sophisticated requirements for storing, managing, searching, accessing, and sharing complex multimedia materials. In this paper, we design and implement a comprehensive multimedia material library system (MMLS), which is built on the relational database management system and the content management middleware. To support metadata queries effectively, we design and refine our own integrated metadata schema fit for digital media industry. Furthermore, a novel query expansion method, which is based on the combination of HowNet and co-occurrence statistics between material description and query keywords, is proposed to search multimedia materials semantically related to query keywords. To enhance user's experience, we adopt Flex based RIA and Web 3D techniques to interact with materials.
