This article describes the Layered Domain Class system (LDC), a state-of-the-art natural language processor whose major goals are (1) to provide English-language retrieval capabilities for medium-sized office domains that have been stored on the computer as text-edited files, rather than more restrictive database structures and (2) to eliminate the need to call in the system designer when extensions into new domains are desired, without sacrificing the depth or reliability of the interface. Early developments in the design of portions of LDC were presented at NCC-83, and the entire system became operational in July 1983. The article gives an overview of the construction of the system, gives examples of the English structures provided for, briefly describes the most recently completed portions of the system, and mentions current directions the project is taking.
