The extension is called HPRL (Heuristic Programming and Representation Language) . The declarative representation of reasoning knowledge in the same formalism that is used to represent domain knowledge results in a powerful tool for the construction of expert systems . Reasoning knowledge is easy to describe, examine and modify . Rules can be reflexive, allowing the construction of powerful meta-rules. HPRL runs on a Vax 11/780 , and on the HP-9836. It has been used for various exploratory projects at Hewlett-Packard, including a program to diagnose faults during IC manufacturing, a program for analyzing dual-channel ECG information to diagnose arrhythmias, and a program for analyzing spectra from infrared and mass spectrometers.","doi":null,"url":"https://ijcai.org/proceedings/1983/51","pdf":"https://ijcai.org/proceedings/1983/0051.pdf","markdown":"https://ijcai.org/proceedings/1983/51.md","bibtex":"https://ijcai.org/proceedings/1983/bibtex/51","volume":{"slug":"1983","title":"Proceedings of the Eighth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1983","url":"https://ijcai.org/proceedings/1983/","year":1983,"location":"Karlsruhe, West Germany","dates":"","editors":"Alan Bundy","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Expert Systems","track":"Expert Systems","number":51,"pages":{"first":215,"last":216},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
