Effects of the number of abstracts obtained on retrieval, recall, and content of relationships. To measure Chilibot's level of recall, a total of 770 known relationships specified in the Database of Interacting Proteins (DIP) was used as a reference set. A. Distribution of the number of sentences describing relationships when a maximum of 5–50 abstracts were selected for retrieval. For each group, the average number of sentences documenting a relationship is reported. Of the 770 known relationships, the histograms show that an increasing number of relationships are documented by a larger number of sentences when a greater number of abstracts are specified for retrieval. B. Increasing the specified number of abstracts for retrieval from 5 to 50 had no affect on the recall of total relationships, although there were changes within relationship categories (e.g., stimulatory/inhibitory).
