From: GeneRIF indexing: sentence selection based on machine learning
GeneRIF and sentence distribution. The y-axis denotes the number of GeneRIF sentences while the x-axis denotes the position of the sentence in the title and abstract of the citations. The position 1 is for the title, position 2 is the first sentence of the abstract and then increases by one. The negative numbers at the end of the x-axis denote the position of the sentence from the end of the abstract. The position -1 is for the last sentence of the abstract.
