本文提出一個由「系統」、「內容」與「社群」三要素所構成的「維基協作金三角模型」,並應用於數位典藏計畫中,作為內容加值與知識匯集平台。基於此一模型,我們首先對眾多維基引擎進行比較分析,以選擇最適合的系統;接著,以台灣棒球新聞數位典藏庫為基礎,以維基協作系統為平台,運用知識組織技術,如分類、索引、索引典與控制詞彙等,進行內容加值與知識匯集,以提升數位內容品質;最後,隨著資料量及社群規模日益成長,則探討如何提高社群成員的互動與參與,使社群之運作與經營更上軌道。This paper proposes a model called “The Golden Triangle for Wiki Collaboration”, composed of three elements: system, content, and community. The proposed model is used in a Digital Archives Project as a means of value adding and knowledge aggregation. We first compared and analyzed multiple wiki engines to select the best system for our research purpose. We chose Taiwanese Baseball News Digital Archive as the base of the research project and the wiki collaboration system as the platform. In order to improve and enhance the quality of digital content, we took the approach of applying techniques of knowledge organization, such as classification, indexing, thesaurus, and controlled vocabularies, so that value and knowledge can be added and aggregated. As the data and community grow, interaction of community members becomes crucial. Therefore, we discussed ways to encourage group interaction and participation from the operational and managerial point of view.
