A survey of chatterbots is presented along with their brief background including their emergence, description of the first programs of this type and some of their modern commercial and educational applications. A Chatterbot is a computer program that is designed to simulate an intelligent conversation with one or more human users. To put it more simply, this is a program that, ideally, "communicates" with a person on an equal footing;it somehow analyzes human cue words or phrases and gives appropriate reasonable responses. Such programs are also called virtual agents or chatbots (from the term "ChatterBot," which was originally coined by Michael Mauldin in 1997). In the general case, these may be systems that recognize and reproduce both written and oral speech, although sound recognition is a separate problem that is beyond the scope of our current consideration;further it will be assumed that the programs we deal with have a character interface.

An automated method for coding hospital patient records is described, which uses a combination of simple computer programs and a structured dictionary. The system accepts unrestricted medical language in French as input, and generates code combinations which represent the semantic values of the original statements. The coding structure is the trial version of the Systematized Nomenclature of Medicine (SNOMED). A prototype system has been developed from a 20,000 word corpus of obstetrical and gynecological data, recorded from patient records written by French-speaking Quebec physicians. Preliminary test results on a small sample show that the system generates accurate codes and code combinations for 97.9% of the data tested. The programs were written in Fortran IV and implemented on a DEC PDP-9 computer. The dictionary keys are word segments and the entries contain operators, word segments and SNOMED codes. The dictionary structure permits a single entry to generate multiple SNOMED codes and to handle the types of linguistic paraphrase found in hospital records. The SNOMED codes and code combinations constitute a metalanguage which provides the means for data compression and uniform representation of naturallanguage medical data.
