A New Graphic Indexing Method of Generic Chemical Structure / 世界科学技术-中医药现代化

ABSTRACT

The generic chemical structure can express succinctly and can realize large protection range, so it is widely used in chemical, pharmaceutical patents. But because of the complexity and the variety of generic chemical structure,the existing domestic patent retrieval system is unable to realize its retrieval. Efficient processing and depth of indexing for this kind of information is also the industry's problems. In order to construct one-stop service system of intellectual property, to realize the retrieval of generic chemical structure, we develop a new indexing method on the basis of the original GFL indexing language. The method further optimizes the definition of a super atom, regulates the selection principle of indexing term and the typical structure indexing to make the super atom play a greater role in the indexing and retrieval of generic chemical structure, so the method not only can improve the retrieval efficiency and convenience, but also can reduce the cost of indexing.
