Area of Science:

  • Systems biology
  • Computational biology
  • Mathematical modeling

Background:

  • Complex biological processes require mathematical modeling for simulation.
  • Systems biology relies on solving numerous parameterized differential equations.
  • Parameter measurement is costly and literature searches are time-consuming.

Purpose of the Study:

  • To develop a text mining system for efficient retrieval of experimental kinetic model parameters.
  • To support researchers in identifying necessary data for computational models.

Main Methods:

  • Developed a text mining system utilizing a support vector machine.
  • Classified full-text documents for the presence of experimental parameter data.
  • Evaluated the system on a manually tagged corpus of 800 documents.
