6.6 Retrieval of Knowledge Representations 153
Figure 6.4 Other documents that match a query. The knowledge representations
shown on the left show the part of the query that occurs in the documents on the
right.
Summary
- Translating natural language text to a representation language that cap-
tures meaning remains an unsolved problem, but reasonably good know-
ledge representations are possible. - Knowledge representations can be queried in two ways:
- Using a formal query language
- Matching against another knowledge representation
- Systems that use knowledge representation matching are now available.
Such a system allows one to query a corpus using natural language.
