Previous experience showed that it is very difficult to create Asbru plans based on the original guideline (formulated in English or any other natural language) in a single step. An intermediate representation is needed to divide the abstraction step from nearly unformatted free text to a precise notation such as Asbru.

In the framework of the Protocure II project we developed MHB (the Many-Headed Bridge to guideline formalization). Its syntax is based on XML and allows enough freedom to model vague concepts from the original guideline text while organizing the information in a structured way and with defined semantics.

The guideline is dissected into chunks of information. The aspects of each chunk are described along eight different, independent dimensions. These are: control flow, data flow, temporal aspects, evidence, background information, patient-related aspects, resources, and document structure.

Using the DELT/A, the links between the original guideline text, its representation in MHB, and its representation in Asbru are easily maintained. This ensures easy tracking of misunderstandings, modeling flaws, and abnormalities in the original guideline text.

An additional advantage of MHB is its independence from Asbru. Therefore, the knowledge engineer using MHB does not need to know Asbru and an MHB model of a guideline can be used as a basis to model the guideline in other representations such as GLIF, too.
