Limitations of current techniques to detect Obligations and Rights in SLA

The need to know and understand the obligations and rights contained in service agreements (also known as Customer Agreement) has generated interest in the industry, and there are numerous projects and tools available for the automatic detection and interpretation of obligations and rights. This is especially beneficial for the customer, as it allows them to automatically know the commitments and risks associated with the use of cloud services, as well as for the provider, who can detect potential liability gaps in the agreement. However, existing tools are only able to extract and partially identify this information. In this study, three limitations have been identified in the patterns proposed by some of the recent techniques to extract information from service level agreements (SLAs). In particular, situations in which some obligation or right is not detected, causes for which they can be misclassified and scenarios in which the actor that performs the action is not detected. In addition, a possible solution to these obstacles is proposed.
