- Abstract
- This dissertation discusses, explains, and demonstrates a new algorithm for translating chemica l nomenclature into molecular formulas. In order to place the study in its proper context and perspective the historical development of nomenclature is first discussed, aa well as other related aspects of the chemical information problem. The relationship of nomenclature to modern linguistic studies is then introduced. Tire relevance of structural linguistic procedures to the study of chemical nomenclature is shown. The methods of the linguist are illustrated by examples from chemical discourse. The algorithm is then explained, first for the human translator and then for use by a computer. Flow diagrams for the computer syntactic analysis, dictionary Iook-up routine, and furmula calculation routine are included. The sampling procedure for testing the algorithm is explained and finalIy, conclusions are drawn with respect to the general validity of the method and the dirsction that might be taken for future research. A summary of modern chemical nomenclature practice is appened primarily for use by the reader who is not familiar with chemical nomenclature.
