A method of generating conceptual graphs representing the meanings of real natural language texts is advanced. Three language specialists are employed, each of which may make a contribution to the final conceptual structure. A syntactic specialist trys to assemble a graph by maximally joining graphs accumulated while recursively ascending a phrase structure tree from a syntactic parser. A semantic specialist trys to fill thematic role slots in template graphs by the successive application of selectional constraints to alternatives. A pragmatic specialist trys to classify text according to its intended purpose as a speech act, and handle idioms. Methods of deciding between policies for controlling the specialists and integrating the contributions of the language specialists, to be used by a control specialist, are described. An implementation capable of handling real direction texts for physical navigation is under development.
