The greatest limitation of the agent is the genericness of its sentence templates, although this must be weighed against the goal to prevent the agent from becoming too dependent on the user for background information. If the agent requires too much input, it loses its appeal as a work-saving device. In order to provide a glimpse of the variety of states represented in the model, and to further illustrate some of the limitations in LetterGen's generation ability, this section presents an example of a message aimed at terminating a cordial relationship. Because cordial relationships require mutual feelings of liking, the simplest way of terminating such a relationship is for one to indicate one's dislike of the other person. A less direct method is to induce the other person to dislike oneself.
Blame is suggested because it gives an impression of one's disrespect for the other person.
That is, at the current stage LetterGen does not know what to express anger about, what trait to denigrate, and so forth. Therefore, LetterGen is much more dependent in this case on the user to provide focussed content for the acts in the form of input text. It seems possible that focussed situations could be inferred if LetterGen could use its model to parse the user's e-mail. But a history of interaction with the user and with his correspondents is likely to be more helpful. Figure 4 A letter aimed at terminating a cordial relationship 5.
