A quality control system has been developed for the purpose of the improvement of the quality of 1H-NMR spectral databases. The system, SpecQC, compares the data of a compound in the database with the predicted 1H-NMR chemical shifts for the compound using a knowledge base and verifies the quality of the data. The SpecQC system is able to evaluate a large number of data in the database in a batch mode and to divide them into three classes according to quality. It makes it easy to recognize erroneous data and to maintain a high quality database by means of modification.
