  "term": "Probability-based matching",
  "field": "Chemistry",
  "definition": "A method used in mass spectrometry for identifying unknown compounds by comparing their experimental mass spectra to a library of reference spectra. This technique assigns a statistical score based on the likelihood that the unknown spectrum matches a particular reference spectrum, considering peak intensities and m/z values. It accounts for variations and uncertainties in both experimental and library data.",
