  隨著網際網路技術的發展,越來越多的教學資訊充斥在網路上。然而大多的教學資訊都是教材提供者所設計,而非是經過同樣且有系統的整理的。這將導致這些分散在網路上的教學資訊無法充分的讓其他的教材提供者或是學習者有效的再利用,學習者也往往無法得知該如何在這些教學資訊中找出一條正確的學習路徑。
  本研究提出了一個基於正規化概念分析(Formal Concept Analysis, FCA) 的理論為基礎的方法,再配合一個經過改良的TF-IDF(Term Frequency-Inverse Document Frequency)資料前處理方法-Adapted TF-IDF(ATF-IDF)所產生出來的二元關係矩陣以建立起一個概念方格(Concept Lattice),用以表達不同概念之間的階層關係,接著藉由本研究提出的學習路徑建構機制,對概念方格做學習路徑的尋訪,找出一個學習路徑。
  With the development of the Internet technology, more and more study materials abound in the Web. However, most of these are designed and structured by the notion of material providers, but by a systematical way. It will make it not efficient for most materials to be reused by the other material providers and learners. And it also makes learners confusing about how to find the way, the learning path, crossed with these study materials.
  In our research, we introduce an Automatic Learning Path Constructing Mechanism, based on the theory of formal concept analysis (FCA) with a binary relation matrix which is pre-processed by an adapted TF-IDF (ATF-IDF) methodology, to find out a concept lattice that shows the concept hierarchy between different concepts, and then output a learning path by learning path traversal methodology.
