Claim:
1. A method for confidence weighting relationships between complex entities in unstructured data, the method comprising: extracting, from a knowledge graph corresponding to the unstructured data wherein the knowledge graph comprises a set of tokens, an expressed relationship between a subset of the set of tokens, wherein tokens in the subset of tokens are related in the expressed relationship by a set of predicates; determining, in the unstructured data, a number of occurrences of the set of predicates; determining, in the unstructured data, a number of occurrences of the expressed relationship; and computing, using a processor and a memory, and using the number of occurrences of the set of predicates and the number of occurrences of the expressed relationship, a confidence value; assigning the confidence value to the expressed relationship; regarding the set of predicates as a single complex predicate; and counting, in the number of occurrences of the set of predicates, an occurrence where the complex predicate appears in the unstructured data in relation with a second subset of tokens in the set of tokens.
