Protocol Analysis involves the identification of basic knowledge objects within a protocol, usually a transcript. For most projects, this makes use of categories of fundamental knowledge such as concepts, attributes, values, tasks and relationships. So, for example, an interview transcript would be analysed by highlighting all the concepts that are relevant to the project. This would be repeated for all the relevant attributes, values, tasks and relationships.
In some cases, more detailed categories will be used for the identification depending on the requirements of the project. For instance, if the transcript concerns the task of diagnosis, then such categories as symptoms, hypotheses and diagnostic techniques would be used for the analysis. Such categories may be taken from generic ontologies and problem-solving models.
