This chapter considers the question of how to locate appropriate multimedia objects. The traditional use of Web search engines is limited by the fact that there are as of yet no standard XML tags describing the many various types of multimedia objects. The users would much prefer to choose from menus, especially from a classification hierarchy where subclasses are all listed. Traditional SQL re...

Every injective function has an inverse, although constructing the inverse for a particular injective function can be quite tricky. One common instance of inverse-function pairs is the binary encoders and decoders used to convert in-memory data into and out of a structured binary format for network communication. Ensuring that a given decoder is a proper inverse of the original encoder is parti...

We consider the on-line learning problem for binary relations defined over two finite sets, each clustered into a relatively small number k, l of ‘types’ (such a relation is termed a (k, l)-binary relation), extending the models of [3, 4]. We investigate the learning complexity of (k, l)-binary relations with respect to both the ‘self-directed’ and ‘adversary-directed’ learning models. We also ...
