However, most of the existing techniques and algorithms only take activities into account. There are several different approaches for the automatic detection of correspondences.

The Refmod-Mine/NSCM algorithm conducts an n-ary cluster matching, thus, the nodes of all models which should be matched are being compared pairwise,

& Flynn, 1999) cluster algorithms start with clusters of size 1 (activities) and consolidates two activities to a cluster

Finally, the algorithm returns binary simple or complex matches for the nodes of each model pair. 4. 2 Structural Analogies One of the main problems in reference modelling is the identification of correspondences (cf. 4. 1)

In order to match (cf. 4. 1) further elements, it is necessary to use advanced mapping algorithms that are able to identify antonyms like invoice settled and payment received.

They propose using algorithms to parse labels written by modelers in order to detect grammatical mistakes and to prompt users to fix them. 3. 2 Use a Glossary As naming conventions only refer to standardizing the grammatical part,

An algorithm can then parse his sentence and deconstruct it into its parts. This allows not only a verification of the phrase structure, i e.,

Not only can this help to create more clearly arranged models (provided that the algorithm is good),

These conventions should be codified in the form of a layout algorithm which is the same for each modeler.

Decision-making algorithms can be used to compile and present to the user recommendations about how to perform their job in alignment with the organization's priorities.

Then, using all these pieces of information it becomes possible to identify points for integrating concrete control activities into workflows. This can be realized by having automated search algorithms check the actual control parameters against the workflow instance information.
