The key idea is that the learn mg. cau be nude easy, g1vrn the right initial computational structure: syntactic knowledge is separated mto a fon·d mtrrprctcr and a variable set of h1ghly constramed pattern-action grammar rules. Only the gramma1 rulf's arc learned. via mduct1on from example sentences presented to . the program. The Interpreter is a s1mpllf1ed vers1on of Marcus's parser for English [1). which parses sentences without backup. The currently Implemented program acquires about 701. of a s1mplihed core grammar of English. What seems to makr the mductJon easy 1s that the rule structures and their actions are highly constrained: there are only four actions, ;~nd they manipulate only very local parts of the parse tree.","doi":null,"url":"https://ijcai.org/proceedings/1979/15","pdf":"https://ijcai.org/proceedings/1979/0015.pdf","markdown":"https://ijcai.org/proceedings/1979/15.md","bibtex":"https://ijcai.org/proceedings/1979/bibtex/15","volume":{"slug":"1979","title":"Proceedings of the Sixth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1979","url":"https://ijcai.org/proceedings/1979/","year":1979,"location":"Tokyo, Japan","dates":"August 20-23, 1979","editors":"Bruce G.
