Claims24
A method for generating characteristic multiword expressions, the method comprising:
- receiving, at least one or more processor, a string of text;
- generating, by the at least one or more processor, at least one lexical chain from the text, wherein the at least one lexical chain comprises at least one noun;
- determining, by the at least one or more processor, whether the lexical chain comprises an adjective, wherein the adjective is at least one of:
- a non-characteristic adjective and a characteristic adjective;
- removing, by the at least one or more processor, the non-characteristic adjective from the lexical chain where the non-characteristic adjective appears before at least one of:
- the characteristic adjective, the non-characteristic adjective and the noun.
A method for constructing a search index, the method comprising:
- receiving at least one characteristic multiword expression from at least one document to be indexed;
- storing a location of at least one sentence in the document that references the at least one characteristic multiword expression;
- computing a contribution score of the at least one characteristic multiword expression to a representation of the document, wherein a characteristic multiword expression representing a key concept in the document receives a higher contribution score than a characteristic multiword expression representing a minor point in the document;
- and
- creating a characteristic multiword expression list of the at least one characteristic multiword expression.
A method for generating characteristic multiword expressions, the method comprising:
- receiving, at least one or more processor, a string of text;

- determining, by the at least one or more processor, whether the multiword expression comprises an adjective, wherein the adjective is at least one of:
- a non-characteristic adjective and a characteristic adjective;
