Rule-based approach for identifying anonymous visitors

A processing system, comprising:

• a memory comprising computer-executable instructions;
• and a processor configured to execute the computer-executable instructions and cause the processing system to:
• obtain a first set of visitor identification records;
• identify a subset of outlier visitor identification records within the first set of visitor identification records;
• create a second set of visitor identification records including all visitor identification records from the first set of visitor identification records other than the subset of outlier visitor identification records;
• create a third set of visitor identification records by applying a first filtering scheme to the second set of visitor identification records;
• create a fourth set of visitor identification records by applying a second filtering scheme to the second set of visitor identification records;
• generate one or more stitched visitor IDs by stitching visitor identification records in the fourth set of visitor identification records;
• and
• determine a stitching accuracy probability for each of the one or more stitched visitor IDs.

A method for managing users, the method comprising:

• obtaining a first set of visitor identification records;
• identifying a subset of outlier visitor identification records within the first set of visitor identification records;
• creating a second set of visitor identification records including all visitor identification records from the first set of visitor identification records other than the subset of outlier visitor identification records;
• creating a third set of visitor identification records by applying a first filtering scheme to the second set of visitor identification records, comprising;
• adding all visitor identification records in the second set of visitor identification records in which a context device ID field is populated to the third set of visitor identification records;
• creating a fourth set of visitor identification records by applying a second filtering scheme to the second set of visitor identification records, comprising:
• determining a set of IP addresses in the third set of visitor identification records;
• and adding all visitor identification records in the second set of visitor identification records associated with an IP address in the set of IP addresses to the fourth set of visitor identification records;
• generating one or more stitched visitor IDs by stitching visitor identification records in the fourth set of visitor identification records;
• create a fifth set of visitor identification records including visitor identification records from the second set of visitor identification records other than visitor identification records from the fourth set of visitor identification records;
• stitch visitor identification records in the fifth set of visitor identification records;
• and
• determine a stitching accuracy probability for each of the one or more stitched visitor IDs.
