Analysis and coding of generic chemical formulae in chemical patents
E. V. Krishnamurthy, Michael F Lynch · Journal of Information Science · 1981
This paper presents a formal linguistic approach to the representation of generic chemical formulae in chemical patents, within the context of use of the ALWIN line-formula notation. The objective of the representation is to permit searches for specific structures and for substructures which are included within the generic expression. The relevance of pattern analysis methods to this problem is highlighted, and preliminary suggestions on algorithm development are put forward.
