Subject matter expert identification and code analysis based on a probabilistic filter

A system comprising:

• a memory having computer readable instructions;
• and
• one or more processors for executing the computer readable instructions, the computer readable instructions controlling the one or more processors to perform operations comprising:
• receiving, by a processor, a portion of code, the portion of code stored as part of a corpus of code;
• inputting the received portion of code to a probabilistic data structure to determine whether the portion of code is similar to one or more other portions of code in the corpus;
• based on determining that the one or more other portions are similar to the received portion of code, identifying a number of similar portions of code;
• storing relationship data that associates the similar portions of code with the received portion of code;
• determining one or more subject matter experts (SMEs) associated with the similar portions of code and the received portion of code, and determining correlations between SME data and the relationship data;
• and
• storing the SME data and the correlations, the SME data including an indication of the determined SMEs, the relationship data correlating the one or more SMEs to the received portion of code.

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by one or more processors to cause the one or more processors to perform operations comprising:

• receiving, by a processor, a portion of code, the portion of code stored as part of a corpus of code;
• inputting the received portion of code to a probabilistic data structure to determine whether the portion of code is similar to one or more other portions of code in the corpus;
• based on determining that the one or more other portions are similar to the received portion of code, identifying a number of similar portions of code;
• storing relationship data that associates the similar portions of code with the received portion of code;
• determining one or more subject matter experts (SMEs) associated with the similar portions of code and the received portion of code, and determining correlations between SME data and the relationship data;
• and
• storing the SME data and the correlations, the SME data including an indication of the determined SMEs, the relationship data correlating the one or more SMEs to the received portion of code.
