A computer program is described which assigns one or more distinct immediate constituent analyses to every German sentence, thus indicating which of all possible sentences any given sequence of words may represent, and revealing all the information implicitly or explicitly contained in each of these sentences, that can be used in the choice of their translations. | Mechanical Translation December 1958 pp. 114-120 German Sentence Recognition f G. H. Matthews and Syrell Rogovin Massachusetts Institute of Technology Cambridge Massachusetts A computer program is described which assigns one or more distinct immediate constituent analyses to every German sentence thus indicating which of all possible sentences any given sequence of words may represent and revealing all the information implicitly or explicitly contained in each of these sentences that can be used in the choice of their translations. THIS PAPER describes a routine that is based upon a theory of language which recognizes in each sentence of a given language an immediate constituent structure. Prior work on German sentence recognition 12 1 2 3 has been based on a linear view of language. Oswald and Fletcher for example . found that the elements of the language in question and their functional relationships to each other could be treated most efficiently in terms of traditional descriptive grammar. 4 This theory of language that neither explains nor accounts for any features of language other than its linear structure has led them and other investigators to develop routines which merely rearrange lexical items and translate them individually into the output language. Our general method of translation is based on the following assumptions each sentence of a language has one or more discoverable constituent structures there is a finite and manageable number of constructions that make up any given sentence and these constructions except t This work was supported in part by the .
