Area of Science:

  • Biomedical informatics
  • Computational biology
  • Bioinformatics

Background:

  • Biomedical relation extraction (BRE) is vital for understanding life science literature.
  • Early BRE focused on binary relations (e.g., protein-protein interactions) crucial for cellular processes and therapeutics.
  • Recent research emphasizes complex relations, like biomolecular events, which involve more than two arguments and can include other relations.

Purpose of the Study:

  • To provide a comprehensive survey of biomedical relation extraction research.
  • To present a general framework for BRE.
  • To discuss approaches for both binary and complex relation extraction, with a focus on the more challenging complex relations.

Main Methods:

  • Literature review and synthesis of existing research in biomedical relation extraction.
  • Categorization of approaches for binary and complex relation extraction.
  • Analysis of challenges and future research directions in complex relation extraction.

Main Results:

  • A general framework for biomedical relation extraction is presented.
  • Existing methods for binary and complex relation extraction are discussed.
  • Key challenges in complex relation extraction are identified, along with potential solutions.

Conclusions:

  • Complex relation extraction presents significant challenges but is crucial for advancing biomedical research.
  • Future directions include developing more sophisticated methods to handle the intricacies of complex relations.
  • Accurate extraction of complex relations from literature will accelerate the discovery of new therapeutic strategies.
