The invention discloses a multi-platform data release method, comprising: a preset database, the database includes a plurality of first data fields; acquiring release files of each platform, and the release files include platform labels, release rules, multiple second data fields, The second data attribute corresponding to the second data field one-to-one, establishes a platform label, a publishing rule, and a plurality of second data field associations; performs semantic matching on the second data attribute and the second data field of a plurality of publishing files, and Judging whether the degree of matching reaches the threshold; if so, establishing associations between the second data fields between the platforms; performing semantic matching between the first data field and the second data field, and judging whether the degree of matching reaches the threshold; if so, establishing the second data field A data field is associated with a second data field; the published data is obtained, and the data is released according to the publishing rules and the association of the fields. It can realize the automatic matching of the data release file and the matching database, and the automatic release of the data file.
