Markush-DARC Graphical System for Retrieval of Generic Chemical Structures

Objective

Six parallel sub-projects will enhance the capabilities and efficiency of the Markush-DARC generic chemicals patent information service available through Telesystemes Questel. In the area of chemical patent searching, traditional methods using text, classification systems and fragmentation codes often fail to produce results of high relevance and are difficult to use. For single compound representations, graphical search systems can give high precision and recall but such systems are inadequate for the generic or Markush formulae often used in chemical patents. The Markush-DARC system has recently been developed to meet this need but it still requires a number of improvements to offer a high-performance and cost-effective service to users. This project will focus on aspects such as optimising the search process in atom-by-atom searches,"True Markush-DARC" development (translation between generic and specific chemical terms), the indexing of problematic patents, the treatment of undefined attachments, expert systems to facilitate indexing.
