Title:
"Software Creation: Using Specification and Description Language (SDL) for Capturing and Reusing Human Experts' Knowledge in Software Design,"
Transactions/Magazines/Conferences:
Proc. 7th Int. Conf. on Software Eng. and Knowledge Eng., SEKE' 95, Rockville, Maryland, USA, June 22-24, 1995.

Abstract
Conventional knowledge engineering techniques for acquiring experts' knowledge can not produce quality knowledge due to improper knowledge documentation and informal knowledge acquisition method. We propose a method for knowledge acquisition based on documentation using Specification and Description Language (SDL). SDL is used to describe both the target system and the design process. The main idea is to follow deterministic problem solving behavior of human experts and document it. Then knowledge can be extracted by comparing documents of the successive steps. This knowledge is recorded and reused in similar or novel cases. We propose an implementation of this method in a distributed expert system for software design. The system is implemented on a number of platforms, each consists of an SDL CASE tool and an expert system for applying the design knowledge. The expert systems can communicate and share their knowledge and resources through the internet. This system serves as an experimental platform for the study of groupware design by simulating design of a team of human experts. We have found that through acquiring enough knowledge, this system can generate software in the same way that human designers do.

"Ex-W-Pert Ssytem: A WWW-Based Distributed Expert System,"

1995年度人工知能学会 (第9回) 全国大会, pp. 455-458, Tokyo, Japan, 1995.

Abstract
The World Wide Web (WWW) allows people at remotely located sites to communicate and share their ideas using a common communication protocol. A common use of the WWW system is running a client application, using a browsing tool, by pointing to a local or proxy server to browse files written in the hypertext format that contain anchors addressing other URLs. In this paper a new application of the WWW in a distributed knowledge based system is introduced and applied to a teamwork design. First, an architecture for a WWW-based Distributed Expert System (Ex-W-Pert System) is proposed and, second, an implementation of the proposed structure in groupware design is demonstrated. The resources and knowledge bases are distributed and can be accessed through the internet.

Title:
"High Quality Design Using SDL Technology,"
Transactions/Magazines/Conferences:
Proc. SDL Forum '95 - With MSC in CASE, Rolv Braek and A. Sarma, eds., pp. 139-150, Elsevier Publishing Co., North-Holland, 1995.

Abstract
This paper describes a design procedure with documentation for embedded software systems aiming at high quality. It starts from process level design. A system is decomposed to several orthogonal processes by data flow division. Making each block or process mono-functional and repeating the division, the system is reduced to a hierarchical cluster of Extended Finite State Machines. The design proceeds by converting an abstract level message sequence chart to multi-process message sequence charts, to a state diagram for one trace, and finally to a state diagram including all traces. Each state transition route is finally converted to source code. A design of an embedded system is thus partitioned to many small step designs each accompanied with the interfacing documents. Through careful, rigorous and repetitive documentation and check, the overall error rate is decreased. Experiments based on applying this method in developing skills of software design and education are reported.

Abstract
本論文は設計における系統的なエキスパートシステムの構築方法を報告する.系統的な設計作業工程を前提として,工程毎の図面から設計の知識を系統的に再現できる.それは階層的に工程毎のデータフロー図とフローチャートで表現される.設計情報,設計知識の構成方法を定め,標準化し規約化した.データと機能を階層的に小さなステップで展開/詳細化し,標準化していくことによりエキスパートシステムを系統的に開発でき,かつ容易化する.これは知的CASEツールの基礎ともなりえる技術である.

Abstract
電話交換のためのスイッチ網を制御するプログラムの設計の知識を報告する.まず正常動作の設計から抽出した知識として上位の呼のプロセスから発着信を分離した複数プロセスへの分割,状態の差によるタスクの発生,及びタスクの詳細化について,次に準正常動作を自動付加するための知識及び評価について述べる.設計繰り返しにともなう知識数の増加には習熟効果がみられた.さらに自動生成を支援する機能として,人手介入のためのチェック,上位情報への補完機能について報告する.現在知識抽出,及び自動生成システムがもつべき外部機能の洗いだしを終えており,これらをExpert System化し自動生成させることが今後の課題である.

Abstract
通信技術は飛躍的に向上し、ホワイトカラーはその進歩に見合った効率向上を要求されている。しかし利便性向上は得られていない。本研究は、ホワイトカラーを付帯業務から解放するべく、付帯業務を電子秘書に代行させることを目指している。優れた秘書の判断と行動をモデル化することにより、その知識を実現容易な形で獲得する。今回は企業幹部などの高級秘書の通信における、やりとり・判断・プロトコルの調査、モデル化について報告する。
