In this chapter, the MoVR framework is proposed for the mobile-based video retrieval system development. This framework can support not only basic event queries but also the complicated queries toward some temporal event pattern, which consists of a set of important events followed by a certain temporal sequence. More importantly, this framework is capable of providing both personalized recommendations and generalized recommendations. Users can also specify a fuzzy weight parameter if their query interests have not yet been clearly formed. The system will make the adjustment and generate different retrieval results based on the fuzzy-associated queries. In essence, MoVR is designed to provide not only powerful retrieval capabilities but also a portable and flexible solution to the mobile users.
As shown in Figure 21.3, the overall framework of MoVR includes three main processing phases on the server side.
