1. A method for adaptively analyzing a natural language document containing at least one lexical item, said analysis to determine an attitude of an author towards an entity, comprising:
- determining at least one actual valence for the at least one lexical item by analyzing the at least one lexical item in context;
determining the attitude based on the at least one actual valence;
associating the author, the entity and the attitude;
wherein the at least one lexical item encodes attitude information about the entity;
determining at least one base valence for the at least one lexical item; and
wherein analyzing the at least one lexical item includes adjusting the at least one base valence based on a contextual valence shifter (CVS) which can have a negative impact on the at least one base valence if the consequences of a not born-out expectation are negative and can have a positive impact on the at least one base valence if the consequences of the not born-out expectation are positive.

31. A system for adaptively analyzing a natural language document containing at least one lexical item, said analysis to determine an attitude of an author towards an entity, comprising:
-
a base valence calculator to determine at least one base valence of the at least one lexical item; a contextual valence adjuster coupled to the base valence calculator, the contextual valence adjuster to adjust the at least one base valence based on at least one contextual valence shifter (CVS) which can have a negative impact on the base valence if the consequences of a not born-out expectation are negative and can have a positive impact on the base valence if the consequences of the not born-out expectation are positive; an entity identifier to identity the entity; an attitude mapper coupled to the entity identifier and the contextual valence adjuster, the attitude mapper to determine the attitude based on the at least one adjusted valence and to associate the author, the entity, and an attitude. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47)

48. A machine readable medium having instructions stored thereon that when executed by a processor cause a system to:
-
determine at least one actual valence for the at least one lexical item by analyzing the at least one lexical item in context; determine the attitude based on the at least one actual valence; associate the author, the entity and the attitude; wherein the at least one lexical item encodes attitude information about the entity determining at least one base valence for the at least one lexical item; and wherein analyzing the at least one lexical item includes adjusting the at least one base valence based on a contextual valence shifter (CVS) which can have a negative impact on the base valence if the consequences of a not born-out expectation are negative and can have a positive impact on the base valence if the consequences of the not born-out expectation are positive. - View Dependent Claims (49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62)
