A Structured History for Command Recall
- Univ. of California, Davis, CA (United States); Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)
- Electrotechnical Lab., Tsukuba (Japan)
The purpose of a history is to provide access to previously used commands. A structured history is a database of commands that were previously executed by a user, together with methods for storing and recalling these commands. Two models and their implementations are presented here. The first model stores all commands eliminating duplicates and short commands. Retrieval is by pattern matching of several different types, frequency, and time. The second model is a parallel distributed processing model that presents the user with a list of likely candidates for good matches to an input string. The PDP history allows for misspellings and retrieves a list of related commands. The implementations are compared. Report contains 17 refs. and 3 figs.
