Expressive Power of Knowledge Representation Systems

Article Abstract:

Several methods of representing knowledge have been developed over the last few years. The knowledge represented by each method becomes incomplete when the objects cannot be distinguished by their attributes. The definability of concepts of knowledge are influenced by this incompleteness. The indiscernibility relations become tools for representing the expressive power of a method. A logic is developed for defining and expressing properties of knowledge representation systems. The axioms and inference rules of the logic are discussed.

The Influence of Rule-Generated Stress on Computer- Synthesized Speech

Article Abstract:

An observed interaction between stress and context appears to be a synergistic effect on the intelligibility of computer-synthesized speech. Incorrect stress decreases the intelligibility of sentences. Under the Liberman-Prince theory, the prosidic feature of stress placement is studied by the author. The experiment results were discovered using statistical techniques on a student population of thirty-six subjects divided into three groups.
