    Area of Science:

    • Bioinformatics
    • Computational Biology
    • Biomedical Informatics

    Background:

    • Interaction Article Classification (IAC) is vital for extracting Protein-Protein Interactions (PPIs) from biological literature.
    • Current text representation and feature weighting methods are suboptimal for IAC.
    • Biological domain knowledge, specifically gene mentions, can enhance IAC.

    Purpose of the Study:

    • To develop a novel approach for Interaction Article Classification (IAC).
    • To improve the efficiency of identifying articles that describe Protein-Protein Interactions (PPIs).
    • To leverage biological domain knowledge, particularly gene mentions, for better text representation and feature weighting.

    Main Methods:

    • Developed a gene mention order-based approach for text representation.
    • Introduced a novel feature weighting scheme, Gene Mention-based Term Frequency (GMTF).
    • Incorporated gene mention information into text representation and feature weighting.

    Main Results:

    • The proposed gene mention order-based representation enhances text representation for IAC.
    • The Gene Mention-based Term Frequency (GMTF) scheme improves feature weighting.
    • The developed Interaction Article Classifier (IACer) outperforms existing leading systems.

    Conclusions:

    • The novel gene mention-focused approach significantly improves Interaction Article Classification.
    • Leveraging domain-specific knowledge like gene mentions is effective for biological text classification.
    • The IACer system offers a more efficient method for extracting PPI information from scientific literature.
