KB005475: Relation score, On what basis do I reduce it in a pathway analysis -GeneSpring GX10. 

The Relation score indicates a confidence matrix on the quality of relations in the pathway database in GeneSpring GX. All relations derived from curated databases like IntAct and all user created relations are given a score of 10 (highest score). For the NLP derived relation, the relations are graded on a scale of 1-9, the best being 9 and the weakest is 1. The score properties are internally calculated based on the number of references and the syntax of the sentences. NLP derived relations have lower score than any curated or user derived relations.
Each reference associated with a relation is graded on a scale of 1- 9, based on the semantics rules of the NLP, the weakest being 1 and the strongest being 9. This property is called the RefScore of the reference. Any relation supported by at least one reference of Refscore 9 or having 3 or more references supporting it, is graded as 9.
