a priority score that sums four individual components with modulating factors that the users are free to adapt. Among those four components, the Feature Component is defined as the ratio of the number of specific and unannotated features over the total number of features of each extract. A cursory examination of the underlying logic behind this ratio reveals that the annotation status of each feature (annotated or unannotated) is established on the identification results of any given tool without paying attention to the confidence of the proposed outputs. A possible weakness of Inventa is that when a given component is matched by only one tool, Inventa treats results independently of the source, thus discarding possibly important quality information. In 2022, Zdouc et al. introduced FERMO, a dash board application that aims to prioritize molecular features from mass spectrometry data. This tool calculates a novelty score by matching data against both a user-provided spectral library, and an precalculated embeddings library of over 300.000 mass spectra, using the MS2Query algorithm .
