Probabilistic matching of web application program interface code usage to specifications

A non-transitory computer readable storage medium tangibly embodying a computer readable program code having computer readable instructions that, when executed, causes a computer device to carry out a method of matching an application program interface (API) code usage with an API specification, the method comprising:

• receiving a program having an API code usage;
• extracting features from the API code usage;
• extracting features from meta data of a plurality of API specifications;
• for each API specification of the plurality of API specifications, determining a match probability with the API code usage;
• determining an API specification having a highest probability;
• and
• matching the API code usage with the API specification having the highest probability.

A computer implemented method comprising:

• receiving a program having an API code usage;
• extracting features from the API code usage;
• extracting features from meta data of a plurality of API specifications;
• upon determining that an exact match between the API code usage and the plurality of API specifications cannot be performed:
• for each API specification of the plurality of API specifications, determining a match probability with the API code usage;
• determining an API specification having a highest probability;
• matching the API code usage with the API specification having the highest probability;
• and
• upon determining that the API specification having the highest probability is below a predetermine threshold, identifying the match as a failure and generating a notification indicating that a probabilistic match could not be performed.
