- Abstract
- A summary of brain theory is given so far as it is contained within the framework of Localization Theory. Difficulties of this "conventional theory" are traced back to a specific deficiency: there is no way to express relations between active cells (as for instance their representing parts of the same object). A new theory is proposed to cure this deficiency. It introduces a new kind of dynamical control, termed synaptic modulation, according to which synapses switch between a conducting and a non- conducting state. The dynamics of this variable is controlled on a fast time scale by correlations in the temporal fine structure of cellular signals. Furthermore, conventional synaptic plasticity is replaced by a refined version. Synaptic modulation and plasticity form the basis for short-term and long-term memory, respectively. Signal correlations, shaped by the variable network, express structure and relationships within objects. In particular, the figure-ground problem may be solved in this way. Synaptic modulation introduces exibility into cerebral networks which is necessary to solve the invariance problem. Since momentarily useless connections are deactivated, interference between di erent memory traces can be reduced, and memory capacity increased, in comparison with conventional associative memory

- Abstract
- Although the rules for descriptive cataloging have been recodified twice in the past twenty years, there never has been any kind of comprehensive theoretical code for subject headings, despite some suggestions for a code over the years. This essay explains the need for a code, provides historical background, and presents some broad proposals as to the philosophy, structure, and form of the code and what the code should cover. Included is the relation between the proposed code and the Library of Congress' 1984 Subject Cataloging Manual.

- Abstract
- This paper examines how classification schemes provide subject access. Concept arrangement before computers is compared to its role after machine-based exact match techniques have evolved. The change in retrieval techniques corresponds to a change in philosophy of knowledge. Classification schemes, emerging from Aristotelian philosophy, provide conceptual frameworks for direct human interaction to foster reference and communication. Computer-based systems provide access with a different emphasis on conceptual arrangement. Employing a philosophy of knowledge as facets, computer programs use word-frequency analyses, uncontrolled vocabulary, and feedback procedures to define subject access. Classification for machine processing optimizes the power of these systems. Though the influence of Aristotelian philosophy declines, structures for concept communication continue to be instrumental in the efficient operation of computer-based systems. Ongoing classification work can help direct vague inquiries and reflect human and social relationships to knowledge

- Abstract
- It is intuitively clear that putting the cart before the horse is not the same as putting the horse before the cart. It is equally clear that a history of philosophy is different from a philosophy of history. Yet there is no logical relationship, like the AND/OR/NOT functions, which would enable manipulation of these permuted, non-commutative, relationships. In this paper we present a system for automatic handling of ordered sets, states based on these sets, and of differing points of view regarding a Universe of Discourse. We call what we are dealing with 'aspects' and we represent them by means of a new logical function called the 'overlap' function
