ABSTRACT:
A molecular retrieval system and method answering to similarity queries for retrieving molecular structures, stored into a source database (22) and having a required similarity with an input structure, which can contain a set of property regions. A target database (23) stores the molecular structures described in hierarchical way and a knowledge base (24) stores well-known molecular fragments at different levels of description together with a set of physical and chemical properties associated to each fragment. A fragment recognizer (21) analyzes the fragments of the input structure to represent them in a hierarchical way. A query analyzer (25) analyzes the similarity queries and selects the appropriate level of molecular representation on the basis of the required similarity. Matching means (26, 27, 29), when called by the query analyzer (25), perform a matching of the representation of the input structure against the representations of the molecular structures stored into the target database (23) at the selected level of molecular representation.
