Logic of Knowledge Base

This work, in its schematic perspective, presents information resources abut the structure of a lexicon. It provides a clue to the issue of designing computational lexicon for natural language analysis system. Of course, there is a choice of selecting criteria which incorporate theoretical and subjective predilections for lexicon designers. But this attempt involves a sensibility of rediscovering the Nyaya model which specifies the nature of items associated with work. As far as the point of lexical recognition in Indian languages is concerned the Nyaya model would be of immense help for determining the semantic properties of a word. Further, some possible storage schemes may be designed and developed on the basis of the theoretical efficiency of this model for operation in computer. The text consists of the portions from four source texts namely Nyaya-bhasya of Vatsyayana, Nyaya-manjari of Jayanta Bhatta, Tarka-bhasa of Kesava Mishra and Sabdasakti-prakasika of Jagadisa Tarkalankara. The topics of the text may be broadly divided into two major sections such as (i) Category information and (ii) subcategory information. The first deals with the aspects of categories enumerated in Nyaya system, the concept of meaning, the relations that subsists between a word and its meaning, the referent of a word and its meaning, the referent of a word, manifoldness of meaning, valid word and aspects of nominals. The second which deals with subcategory information points to a fact that the concept structure of a word ultimately resorts to a referential set up in which its inherent features are determined.
