Chilibot is a specialized search software for the PubMed literature database. It is designed for rapidly identifying relationships between genes, proteins, or any keywords that the user might be interested. In contrast to the PubMed interface where results are organized based on articles, Chilibot directly presents the key information user is seeking, i.e. sentences containing both of the terms. These sentences are organized into different relationship types based on linguistic analysis of the text.

In addition, Chilibot is especially suited to batch process large number of terms (e.g. microarray results). The relationships are summarized into as a graph, with links to sentences describing the relationships, as well as the terms themselves.
