Chemical information, especially that concerning chemical reactions,
is becoming increasingly available in a variety of computer-readable
databases. 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
artificial intelligence techniques to recognize a range of chemical
diagrams and extract the information they contain.
The steps necessary to transform a chemical structure drawing into
a computer-readable output are detailed.
Several examples are given to illustrate the scope of the current work.
