Zusammenfassung
A method for processing sentences which contain
unknown words, i. e. words for
which no lexical entry exists, is presented.
There are three different stages of
processing:
1. The sentence with the unknown word is parsed.
There are no special
requirements for the parsing algorithm, but the lexical lookup procedure needs to
be modified.
2. Based on the syntactic structure of the parse, information about the unknown
word can be extracted.
3. The information obtained in step 2 may be too fully specified for a lexical entry.
Therefore a filter is applied
to it to create a new lexical entry.
An application of the method is illustrated with examples from Categorial
Unification Grammar.
The problem of using the extracted information for lexical
knowledge acquisition is discussed.
