API asset merging method and system based on URL

The invention provides a URL (Uniform Resource Locator)-based API (Application Program Interface) asset merging method and system. The method comprises the following steps: acquiring host access record log data; extracting a URL (Uniform Resource Locator) based on the access record log data, and segmenting the URI by using a specific separator to form a word set array; according to the word set data, constructing a word relation graph by taking every two words as a relation and taking the words as nodes in sequence, and calculating out-degrees and in-degrees of the words; according to the out-degree and the in-degree obtained in the previous step, through a specified threshold value, selecting a word of which the out-degree or the in-degree is smaller than the specified threshold value; on the basis of the words obtained in the previous step, URIs containing corresponding words are screened out, and URIs with high similarity in the total URIs are calculated through minhash; on the basis of the URI selected in
