Document Retrieval

In Chapter 2 through 5 we discussed the data model, classification and categorization mechanisms for the office documents. Consider a collection of documents to be stored in an information base. From each document, a synopsis of information is extracted to form a frame instance (reminiscent of the tuple in the relational data model). Frame instances can be classified according to their types which are called frame templates (reminiscent of the schema in the relational data model). The frame instances can be categorized based on the nature of their information and are placed in folders. Thus, a folder can contain a collection of frame instances of various frame template types1.
