Natural Language Processing (NLP) can speed up biomedical text curation by up to 33% if its output is accurate. Further studies are needed to confirm curator preferences for specific NLP features.

Area of Science:

  • Biomedical Informatics
  • Computational Biology
  • Text Mining

Background:

  • Text mining and Natural Language Processing (NLP) show potential for enhancing biomedical text curation.
  • However, empirical evidence on the effectiveness and usability of NLP tools for this purpose is limited.

Purpose of the Study:

  • To measure the time saved in biomedical text curation using NLP assistance.
  • To gather subjective feedback on the usability of an NLP-integrated curation tool for protein-protein interactions (PPIs).

Main Methods:

  • Conducted three experiments to quantify curation speed-up with NLP support.
  • Collected qualitative feedback from curators on their experience with the NLP-assisted tool.

Main Results:

  • A maximum speed-up of one-third (33%) in curation time was observed under ideal conditions of perfect NLP accuracy.
  • One curator expressed a preference for consistent NLP output and high recall, suggesting potential user-specific needs.

Conclusions:

  • NLP tools can significantly accelerate biomedical text curation, provided their accuracy is high.
  • Future research should involve multiple curators to validate preferences for NLP output characteristics and further assess tool usability.
