A Gene Network for Navigating the Literature. Hoffmann, R., Valencia, A.

Nature Genetics 36, 664 (2004)

User-Friendly Text mining tool Searches into PubMed abstracts

Uses genes and proteins as hyperlinks between sentences and abstracts. iHOP converts PubMed information into one navigable resource.

80.000 different genes H. sapiens, M. musculus, D. melanogaster…more than 1500 organisms

::: 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.
