Research: Pattern Languages / 研究: パターンランゲージ


Pattern languages are systems of patterns (i.e. good design practices) related with each other in particular domains. We are investigating efficient and effective techniques for extending existing patterns, and natures of existing patterns and pattern languages. At the same time we are forming new pattern languages extracted from our own expertise.

Extending Existing Patterns and Pattern Languages

Constructing a Pattern Language from many patterns facilitates communication and intelligence sharing. However, existing methods of Pattern Mining are so impromptu that it is difficult to mine related patterns. We propose a method that derives related patterns by structuring and utilizing existing patterns in realistic time.

Network Analysis for Patterns and Search

PPRWe applied the technique of network analysis to collection site Portland Pattern Repository (henceforth, PPR) of the software pattern, and centrality was calculated. And the feature of the relation between software patterns was clarified. Moreover, metrics analysis was conducted about the history information of each software pattern. As a result, The degree centrality of the frequently-used software pattern was high value. This is useful to select a software pattern and the extraction of a new software pattern.

A Pattern Language for ET software design robot contest

RoboconThe ET robot contest is software design competitions. Because ET robot contest provide young engineers or students an opportunity to learn embedded software engineering, many people are first time participants and do not know how to develop. Consequently, we have extracted a pattern language consisting of 40 patterns from our technical knowledge and experience on the contests. We name this pattern language ET Robocon Strategy. This pattern language, which is abstractly made, will coordinate with the embedded software engineering and develop a competitive contest for participants and young engineers.
