The invention provides an intelligent data standard directory generation method and device, and the method comprises the steps: obtaining metadata by scanning a to-be-classified data set, carrying outclustering of similar data in the metadata to obtain a plurality of pieces of target data, generating a table name of each piece of target data, and storing the table names in a database in an SQL mode; generating a table name annotation corresponding to each piece of target data according to the data features of each piece of target data; according to the calling popularity, the importance degree, the data timeliness, the data volatility and the information integrity of each piece of target data, comprehensively evaluating each piece of target data, and calculating a comprehensive score level of each piece of target data; and generating a data directory of the plurality of target data by taking the table names, the table name annotations, the calling popularity, the importance degree, the data timeliness, the data volatility, the information integrity and the comprehensive scoring level as columns in sequence. Circulation and management of data assets are realized, data developers are helped to develop and manage comprehensively, automatically and intelligently, and a data user can use data conveniently.
