- LADDER abstract "LIFER/LADDER was one of the first database natural language processing systems. It was designed as a natural languageinterface to a database of information about US Navy ships. This system, as described in a paper byHendrix (1978), used a semantic grammar to parsequestions and query a distributed database. The LIFER/LADDER system could only support simpleone-table queries or multiple table queries with easyjoin conditions.Some examples of queries it could accept:What are the length, width, and draft of the Kitty Hawk?When will Reeves achieve readiness rating C2?What is the nearest ship to Naples with a doctor on board?What ships are carrying cargo for the United States?Where are they going?Print the American cruisers’ current positions and states of readiness?↑".
