Aiming at the classification and identification of un-identified MSTs, the GMD accessed the information on available reference compounds as a source of training data to apply [[decision trees]] (DT) as a supervised [[machine learning]] approach. Single structure feature extraction was applied to classify the metabolite space of the GMD prior to DT training. DT-based prediction of the most frequent substructures classify low resolution GC-MS mass spectra of the linked (potentially unknown) metabolite with respect to the presence or absence of the chemical moieties.
The web-based frontend supports conventional mass spectral and RI comparison by ranked hit lists as well as advanced DT supported substructure prediction. Batch processing is enabled via [[Simple Object Access Protocol]] (SOAP)-based web services while web-based data access services expose particular data base entities adapting [[Representational State Transfer]] (ReST) principles and mass spectral standards such as [[NIST]]-MSP and [[JCAMP]]-DX.
