Function Assertion requires significant user engagement with documents Document attributes are not directly mapped to function, thus not asserted. Categories based on previous function descriptors segment collection for initial examination. Members of categories may fill need. No document attributes asserted. No function attributes asserted.
Single category comprised of all documents provides opportunity for discovery of new connections.
We have suggested a set of relations that may seem quite obvious on the face of it, yet pose difficulties in the absence of verbal representations of image characteristics. We have tried to look at the image retrieval problem through the eyes of producers and image users. Such a model should probably also be able to address all the out of focus and poorly exposed pictures people keep because they serve some purpose. It is, likewise, our hope that taking some of the assertion making responsibility off the shoulders of cataloguers and putting it into the hands of users of the system will generate a more dynamic system that is more richly representative of both the images and the user requirements.
