全国の農業試験場などで実施されている育種・栽培試験のデータの管理および分析支援を実現するデータベースシステムを構築した.育種・栽培試験の現場では,植物を生育する労力だけでなく,データ分析の労力も無視できない.そこで,現場の研究者へのヒアリングや試験事例の文献調査により,育種・栽培試験データをモデル化した.また,このモデルを用いて分析支援システムを構築し,分析作業にかかるデータの可視化作業の効率化を実現した.本システムは,ユーザの利便性を第一に設計し,現場の研究者が普段より使用している表計算ソフトのファイルを用いて容易にデータベースへのデータ登録が行える.また, Webブラウザ上で容易にグラフ表示などの可視化を行えるほか,特定条件のデータのみをダウンロードする機能などにより,現場の分析作業を支援する.本研究では,試験事例である文献を対するモデルの適用性の調査と,実際の育種・栽培試験のデータ分析へのシステムの適用実験により評価を行った.

We developed a database system to store and analyze crop data which are obtained in breeding tests of various plants. In operating breeding tests, researchers pay considerable labor not only for cultivating but also analyzing obtained data. To improve it, we performed a data-modeling of crop data through investigating a number of reports and also through having interviews with several researchers of breeding. By managing crop data with this model, our system enables researchers to analyze the crop data efficiently, which results in reducing analysis labor of researchers. Our system is designed in consideration of usability: researchers can easily store crop data with their own spreadsheet files. They can also analyze the stored data through web browsers with simple operations such as selecting conditions and items to compare. Further, they can search data with conditions and the result can be downloaded. We evaluated our system by applying some breeding tests, and then we obtain good evaluation results with the comment that the system is useful and it reduces the labor of analyses.

現在,博物館などの持つ多様な情報資源を共有化し,提供しようとする動きが盛んである.しかし,これまでのシステムは,共有データの設計の議論が主で,利用者への提供方法に関する十分な議論がなされていない.そこで本研究では,資源共有システムにおける情報提供方法を検討するためには,利用者の検索行動を詳細に分析する必要があると考え,検索プロセスの記録とインタビュー・発話分析を組合せた検索行動調査を行なった.調査の結果,全エレメントを一度に検索できるANYは利用者の検索支援には重要であること, Titleのように格納されている内容の分かりやすいエレメントは効果的に利用できること, Dateのように検索に有効であっても,内部のデータ形式が不明な場合には利用されにくいことなどが分かった.これらの結果をもとに,資源共有システムでの検索エレメントの設計についての考察を行なった.

There are increasing numbers of systems designed to share information resources among different organizations. However, as the main point of discussion of these systems is the method of mapping the metadata element set of each database onto the others', users' viewpoints are kept out of the discussion of constructing systems. This paper aims to analyze user demands by investigating the actual use of information retrieval systems to examine search methods in shared resource systems. People's retrieval processes were investigated using a cognitive psychological experiment, with protocol analysis and interviews. Through a detailed analysis of their information retrieval processes, the following results were found: 1) a query that allows searches on all search elements together is effective for users who do not understand the details of either queries or databases; 2) elements such as 'Title', the definition of which is clear and easily understood, are used effectively; 3) even if an element is effective for retrieval, such as 'Date', it is not used when the format of the values in the element is not shown. Based on the results of this investigation, we discuss a method for constructing search elements in resource sharing systems.

A web platform has been developed for experts to solve a given problem strategically by taking advantage of available information data and/or knowledge. Information handled here are contexts (causal relation, consequence and time dependent properties), contents (textual information about specialized information and values in databases), and know-how (how to use computerized resources including simulation codes). It is the main concern of this prototype platform that a balance of sharing of information and appreciation of intellectual property right. This platform was used among materials experts in US and Japan through internet, and the results by such test users were reported.

Many universities and other research organizations have proceeded construction of academic resource repositories under the leadership of National Institute of Informatics (NII). Because it requires much labor to create metadata contents of academic resources, development of tools or services enabling to easily create metadata contents is expected. This paper proposes a system which converts BIBT_EXmetadata of academic resources - widely used by researchers in science and engineering - into NII metadata format in order to support constructions of academic resource repositories. The proposed system enables to reduce almost four-fifth of workloads of creating metadata contents. In addition, utilizing compiler compiler to develop the proposed system reduced the develop cost.
