1.1 Interoperable Image Search and RetrievalThis Technical Report specifies two things. The first is a framework for interoperability for still image searchand retrieval. The second identifies an architecture and the components in this framework, the linkagesbetween components, and which of these components and links are to be standardized in JPSearch.The image search and retrieval framework will be determined by real use cases (tasks) and will leverage onlessons learnt in the long history of text retrieval where, for example, different users issuing the same querymay be looking for (very) different results. This is important because it means that the framework must begeneral enough to support many possible approaches to image retrieval, e.g., from using only low-level imagefeatures, to text annotations, to community input, or a mixture of such approaches.From the framework and components, and the linkages and flow of data between them, the parts of JPSearchthat need to be standardized can be determined.1.2 MotivationThere are many applications that provide image search and retrieval functionality on computer desktops, onthe World Wide Web (i.e., websearch), on imaging devices, and in other consumer and professionalapplications. These implementations are characterized by significant limitations, including:? Lack of the ability to reuse metadata? Lack of a common query format and search semantics? Lack of a common format for handling context in searching1.3 Outline of the Technical ReportThere will be 7 clauses to this report. They are arranged as follows:Clause 2 provides definitions of terms and abbreviations.Clause 3 reviews the traditional approaches to image search and from various examples, motivates theimportance of the user in the search process, the importance of making explicit the user task and userevaluation, and that meaning in images may be as much added from outside as extracted from the imageitself. This motivates the next clause, which are the real use cases.Clause 4 describes the real use cases of the various ways searching does take place. In particular, therecould be multiple entry points into the overall search framework. These would include automatic, semiautomatic,and human (user) driven searches. These would include specific use cases and motivatingexamples of searches for images.Clause 5 describes the overall search and management process. This can be considered the requirementsspecifications for a general search and management architecture.Clause 6 describes the 4-layer architecture for JPSearch and explicitly identifies the components in thearchitecture, and what their roles and positions are in the architecture. We will describe how the use casesdescribed in Section 3 map to the layers of this architecture.
