چکیده

Expert critiquing systems are a type of humancomputer collaborative system in which a computer agent presents reasoned opinions about a human agent’s problem-solving process for a given task. The challenge in such systems is to provide timely critiques relevant to the user’s focus of attention. A problem with many expert critiquing systems is that their critiques are not always timely or relevant; consequently such systems interfere with problem-solving rather than provide assistance. The problem arises in part from insufficient representations of the human’s problem-solving processes. In this paper, we discuss the flexible use of an agent model based on a task-decomposition hierarchy of human experts in a critiquing system called SEDAR. The model differs from previous research efforts in three ways: 1) the structure of the model, 2) the function the model performs in the expert critiquing system, and 3) the influence of the model on communication between the computer and human agents. A prototype of SEDAR was implemented for the flat and low-slope roof design domain. The results of early testing on the prototype show that SEDAR assists users effectively and reduces the error rate.

ReCognition and Critiquing of Erroneous Agent Actions

An agent can perform erroneous actions. Despite such errors, one might want to understand what the agent tried to achieve. Such understanding is important, for example, in intelligent tutoring and expert critiquing systems. In intelligent tutoring, feedback to the agent--i.e, the student--should focus on which actions made sense and which did not. To achieve such understanding, we propose a com...

Enabling Medical Expert Critiquing Using a Bdi Approach

Critiquing systems do this by providing critique on a physician’s decisions, rather than telling him/her exactly what to do. In order to perform this task, a critiquing system must have knowledge of the diagnosis and the treatment processes, and must be a...

Rule Refinement by Domain Experts in Complex Knowledge Bases

We research how subject matter experts can develop knowledge-based systems that incorporate their expertise. Our approach is to develop a learning and problem solving agent, called Disciple, that an expert can teach by explaining it how to solve specific problems, and by critiquing its attempts to solve new problems (Tecuci 1998). The knowledge base of the agent is structured into an object ont...
