This study shows that top-down decomposition is problematic in the early stages of design. Instead, an opportunistic decomposition is better suited to handle the ill-structuredness of design problems. Designers are observed interleaving decisions at various levels of abstraction in the solution decomposition. The verbal protocols of three professionals(More)
High-level software design is characterized by incompletely specified requirements, no predetermined solution path, and by the integration of multiple domains of knowledge at various levels of abstraction. The application of data-driven knowledge rules characterizes expertise. A verbal protocol study describes these domains of knowledge and how experts(More)
User-adviser dialogues were collected in a typed Wizardof-Oz study (=man-behind-the-curtain study*). Thirty-two users had to solve simple statistics problems using an unfamiliar statistical package. Users received help on how to use the statistical package by typing utterances to what they believed was a computerized adviser. The observed limited set of(More)
A verbal protocol study of professional software designers has revealed three design process control strategies. At least one of them, the generation of <italic>opportunistic</italic> solutions at different levels of detail accompanied by problem domain modeling, had not been observed in previous empirical studies nor had been acknowledged in the software(More)
INTRODUCTION Anaphora resolution is the process of determining the referent of ~uaphors. such as definite noun phrases and pronouns, in a discourse. Computational linguists, in modeling the process of anaphora resolution, have proposed the notion of focusing. Focusing is the process, engaged in by a reader, of selecting a subset of the discourse items and(More)
Key findings from empirical studies&#8212;early design is opportunistic; critical role of pictures in design conception; impact of various cognitive limitations&#8212;have very effectively determined requirements and design for a set of tools to support early design. Key design features of the tools include respectively: (1) The (simultaneous) display of(More)
Video is a powerful medium for capturing and conveying information about how people interact with computers. It provides a record of sequential streams of natural observations, some of which are subtle (body language and eye movements) and difficult to capture in any other form. Video also preserves the context as well as the content of a session and(More)
Advisory systems can be very powerful general tools for users. Formal query languages, menus, and direct manipulation interfaces might not suffice to access advisory systems' full functionality. The capabilities of natural language interfaces could be required. Unfortunately, natural language interfaces are not meeting the needs yet. Wide syntactic coverage(More)
Novice users engaged in task-oriented dialogues with an adviser to learn how to use an unfamiliar statistical package. The users', task was analyzed and a task structure was derived. The task structure was used to segment the dialogue into subdialogues associated with the subtasks of the overall task. The representation of the dialogue structure into a(More)
