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.
