API Usage Pattern Mining

One or more computer-readable media storing computer-executable instructions that are executable by one or more processors to cause the one or more processors to perform acts comprising:

• receiving a query for usage of an API method;
• generating API call sequences based on a codebase, individual API call sequences of the API call sequences including the API method;
• and
• mining the API call sequences to generate an API usage pattern for the API method using a frequent closed sequence mining algorithm.

A system for API method usage data mining, the system comprising:

• one or more processors;
• and
• memory to maintain a plurality of components executable by the one or more processors, the plurality of components comprising:
• a parser configured to collect API call sequences of an API method from a codebase, and
• a miner configured to:
• generate first multiple clusters by clustering the API call sequences,
• determine multiple frequent closed sequences of the first multiple clusters, and
• generate second multiple clusters by clustering the multiple frequent closed sequences, individual clusters of the second multiple clusters corresponding to an API usage pattern for the API method.
