Dear Professor Laurence,
following the SFL theory, I want to see in which processes, i.e. verbs, for example, the word "Britain" is included as a participant (basically, as subject or object). I am trying to get results that rank those verbs according to frequency. If I manage to do that, I plan to label those verbs as processes manually following the transitivity system suggested by Halliday. For example, I might get results that indicate that the most frequent verbs Britain "cooperates" with either as the subject or the object are "create", "construct", "demolish", "modernize", and that will help me conclude that the most frequent type of processes in which "Britain" participates are, in fact, material processes (because all those verbs belong to the category of material processes).
I hope I explained it better now and thank you for your time and patience.
