A list of constituents left to parse to complete the goal. 2For an introduction to chart parsing in Prolog the reader is referred to Covington (1994a) and Gazdar and ...
WebThe Earley parser proceeds one input position at a time, keeping track of all the information that would needed to simulate the parsing threads.
