The invention provides a method for trustworthiness computing of administrative division based on multiple factors. The method comprises the following steps of computing a location tracking factor for an address character string to be inquired; computing division location rank difference factors, division correlation factors and division rank difference correlation factors according to all possible administrative division result sets of the address character string to be inquired; obtaining the sum of division rank difference correlation factors between one administrative division character string and all other administrative division character strings according to the division rank difference correlation factors, multiplying by the location tracking factor of the one administrative division character string to obtain the trustworthiness of the one administrative division character string, and selecting an administrative division result where the administrative division character string corresponding to the maximum trustworthiness is located. A participle result of the address character string to be inquired and all the possible administrative division result set are utilized, and according to the semantic features expressed by address data, the speed and the accuracy of address searching are improved through an appropriate matching algorithm, so that the on-line service quality of a network map is improved, and better location can be provided for users.
