Business process event mapping

A computer readable storage medium comprising a computer readable program for mapping an event type to an activity in a business process model, wherein the computer readable program when executed on a computer causes the computer to perform the steps of:

• tokenizing the event type and the activity by determining event tokens for event type labels in the event type and determining activity tokens for activity labels in the activity;
• generating a score matrix for pairs of the event tokens and the activity tokens indicating a degree of similarity between the event token and the activity token in each of the pairs;
• determining whether the event type and the activity are correlated by determining scores of the pairs of event tokens and activity tokens that are ranked highest in said score matrix;
• and
• outputting a mapping report indicating whether the event type and the activity are correlated in the business process model.

A system for mapping an event type to an activity in a business process model comprising:

• a tokenizer configured to tokenize the event type and the activity by determining event tokens for event type labels in the event type and determining activity tokens for activity labels in the activity;
• a token mapper configured to generate a score matrix for pairs of the event tokens and the activity tokens indicating a degree of similarity between the event token and the activity token in each of the pairs and configured to perform at least one of an assessment of whether any of the event tokens and the activity tokens are natural language synonyms or a determination of a string edit distance between the event token and the activity token in each pair of at least a subset of the pairs;
• and
• a similarity calculator, implemented by at least one hardware processor, configured to determine whether the event type and the activity are correlated by determining scores of the pairs of event tokens and activity tokens that are ranked highest in said score matrix and to output a mapping report indicating whether the event type and the activity are correlated in the business process model.
