::: iHOP Confidence Value.
The synomnym ambiguity limitation Many gene or protein synonyms are ambiguous, thus one and the same synonym is often used for different genes. Even human experts can have difficulties to resolve such ambiguities and automatic systems, like iHOP, will therefore always exhibit certain errors.
The iHOP confidence value Although no definite solution for the problem of synonym ambiguity is in sight, it is possible to put an automatically derived confidence value to specific gene references. This iHOP confidence value is illustrated through the colour intensity of a star
The absence of a star does not mean that a certain term could not be a gene, but simply that supporting evidence is not available.
