Human understanding in design evolves through a process of critiquing existing knowledge and consequently expanding the store of design knowledge. Critiquing is a dialogue in which the interjection of a reasoned opinion about a product or action triggers further reflection on or changes to the artifact being designed. Our work has focused on applying this successful human critiquing paradigm to...

We present a prototype of a novel interactive food recommender for groups of users that supports groups in planning their meals through a conversational process based on critiquing. The system comprises two novel elements: a user interface and interaction design based on tagging and critiquing, and a utility function incorporating healthiness and diet compliance factors.

Current user interface tools provide limited support when it comes to evaluation and usability testing. By adding a critiquing component with evaluation capabilities to the graphical layout tool, design flaws might be detected and comments and critique generated. Although prototypes of such systems have been implemented, little research has investigated how the critiquing component should behav...

Design is a hard problem: ill defined and open-ended. Schön [Schön (83)] characterized the process of designing an artifact as a successive refinement of reflection and redesign. Critiquing the communication of reasoned opinion about an artifact plays a central role in the design process. A computational critiquing mechanism provides an effective form of human-computer interaction to support th...

Product recommendation systems are now a key part of many e-commerce services and have proven to be a successful way to help users navigate complex product spaces. In this paper, we focus on critiquing-based recommenders, which permit users to tweak the features of recommended products in order to refine their needs and preferences. In this paper, we describe a novel approach to reusing past cr...

The ability of a CBR system to evaluate its own confidence in a proposed solution is likely to have an important impact on its problem solving and reasoning ability; if nothing else it allows a system to respond with “I don’t know” instead of suggesting poor solutions. This ability is especially important in interactive CBR recommender systems because to be successful these systems must build t...

Commonsense psychology seems to have it that most morally significant decisions arise through practical reasoning and moral delibaeration. No doubt, there are social psychological data that put pressure on reflective views of human agency. However, even on the assumption that non-rational and irrational processes are implicated in many morally significant decisions (cf., Doris, 2002, forthcomin...

In this paper we investigate the use of Latent Semantic Analysis (LSA), Critiquing Systems, and Knowledge Building to support computer-based teaching of English composition. We have built and tested an English Composition Critiquing System that makes use of LSA to analyze student essays and compute feedback by comparing their essays with teacher’s model essays. LSA values are input to a critiqu...
