This paper describes a programming-by-demonstration system, called Internet Scrapbook, which allows users with little programming skill to automate repetitive browsing tasks.With the system, the user can create a personal page by clipping only the necessary portions from multiple Web pages.Once the personal page is created, the system updates it on behalf of the user by extracting the specified parts from the latest Web pages.The data extraction method in Scrapbook is based on the regularity in modifications of Web pages, i.e. that headings and positions of articles are rarely changed even though the articles themselves are modified.In the experiments to examine the accuracy of the data extraction algorithm, 96 percent of user-specified portions were correctly extracted.

This paper describes a new user interface, called a fingerprint user interface (FUI), which employs fingerprint recognition.While the unique feature patterns of fingerprints have mainly been used for personal identification, the FUI is unique in that it uses not only the differences among fingerprint patterns of different persons, but also the differences among the ten fingers of a single person.In the FUI, the system identifies the finger that has operated (touched) an input device through pattern matching of fingerprints and it performs the task assigned to the identified finger.Since users are able to specify different tasks by using different fingers, they feel as if commands and data objects were actually held on their fingers.

Describes an approach to integrating various knowledge representations for classification problems. Knowledge representation forms have been analyzed: the analysis shows that suitability of representation depends on a given situation. Therefore, a multiple representation form capability and a form conversion capability are necessary to support developing knowledge bases for wide areas of application. A classification problem tool called DECISIONBOX has been developed with the aim of providing experts with an integrated knowledge representation capability. A knowledge base can be represented in a tabular form, a rule form or a tree form, and form conversion can be done at all times. With this integrated representation, an expert is able to build a knowledge base using the most appropriate form.

An approach is described to integrating a classification problem solving function and an interactive knowledge acquisition function on a tabular knowledge representation. A tabular knowledge base presents concept functions in DNF (disjunctive normal form), which handles disjunctive concepts with multiple-value attributes. Because of the peculiar knowledge-base construction, which represents concept functions with positive and negative disjuncts, the knowledge refinement procedures are kept simple, and changes in the knowledge base are comprehensible to users. Based on the approach, a system called DT was developed.>

In troubleshooting large scale equipments, fault localization interferences involve indeterminateness and they might lead to erroneous conclusions. To realize indeterminate inferences, an assumption-based fault localization technique has been developed. The technique allows inferences based on indeterminate assumptions. When inconsistencies are discovered, assumption are revised. The technique also enables flexible diagnosis control, such as reasoning based on anticipated test results without actually carrying out the tests. When the anticipated results become doubtful, it activates the omitted tests. The paper describes the technique and an outline of the troubleshooting expert system for electronic switching systems based on the technique.

A PLA design system called PLAYER has been developed for next generation VLSI products. It supports the top-down design of PLAs from a functional description to a mask level layout with easy-testable features for built-in test. Highly effective optimization and verification tools are provided to realize correct and area-efficient designs.
