The problem yields insight into methodology for representing knowledge in hypothetical reasoning systems. In general, there are not enough constraints in a domain to uniquely determine the approach that a reasoning system should take in formalizing its characteristics, but domain-independent methodological principles can help guide the designer. We present the shared information constraint on the domain of inter-agent communication, which implies an interesting representational duality between speakers (designers of utterances) and hearers ( recognizers of mental state) in a simple communication environment. This work provides insight into default reasoning applications development.","doi":null,"url":"https://ijcai.org/proceedings/1993/163","pdf":"https://ijcai.org/proceedings/1993/0163.pdf","markdown":"https://ijcai.org/proceedings/1993/163.md","bibtex":"https://ijcai.org/proceedings/1993/bibtex/163","volume":{"slug":"1993","title":"Proceedings of the Thirteenth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1993","url":"https://ijcai.org/proceedings/1993/","year":1993,"location":"Chambéry, France","dates":"","editors":"Ruzena Bajcsy","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Natural Language","track":"Natural Language","number":163,"pages":{"first":1179,"last":1184},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
