The Implementation

  • Robert E. Frederking
Part of the The Kluwer International Series in Engineering and Computer Science book series (SECS, volume 41)


In the previous chapter we discussed intersentential ellipsis and some other dialogue phenomena at a theoretical level, to understand in general how they should be treated by a natural language understanding system. In this chapter we will look in detail at the internal workings of a system based on the idea that an interactive dialogue is a single, continuous event rather than a series of separate transactions. This natural language interface is implemented in a production system using an extended chart parsing technique. The first example will be the interpretation of a relatively simple full-sentence input, to acquaint the reader with the basic operation of the system, followed by examples dealing with more challenging situations.
