CHEMICAL LITERATURE DATA EXTRACTION - THE CLIDE PROJECT

Chemical information, especially that concerning chemical reactions, i s becoming increasingly available in a variety of computer-readable da tabases. However, the creation of these databases is a time-consuming and expensive process. CLiDE (Chemical Literature Data Extraction) is a new software project to help solve the problem of building substance and reaction databases. CLiDE uses a combination of imaging and artif icial intelligence techniques to recognize a range of chemical diagram s and extract the information they contain. The steps necessary to tra nsform a chemical structure drawing into a computer-readable output ar e detailed. Several examples are given to illustrate the scope of the current work.
