A priority order of the group is recommended to the learner to be classified. The recommendation module 14 includes the number of the k classified learner samples in the M learning communities. The zero learning community is treated as an unsuitable learning community and excluded, and only the learning communities that contain the k-classified learner samples that are not zero in the M learning communities are ranked. And the recommendation module 14 designates the learning community including the most of the k classified learner samples among the M learning communities as the highest priority recommendation to the learner to be classified.
參閱圖1與圖2,本發明網路式學習社群推薦方法之較佳實施例適用於該網路式學習社群推薦系統1,該方法包含以下步驟。Referring to FIG. 1 and FIG. 2, a preferred embodiment of the network learning community recommendation method of the present invention is applicable to the network learning community recommendation system 1, and the method includes the following steps.
首先,如步驟21所示,該待分類學習者利用該使用者介面模組12輸入該具有多個學習屬性值之待分類學習者樣本,其中該等學習屬性值係根據該待分類學習者於一數位學習平台系統(圖未示)上之操作而取得,其中該數位學習平台系統係以網頁之方式呈現每一章節的教材且可供該待分類學習者上傳作業並可記錄該待分類學習者的操作記錄,關於該數位學習平台系統之建置係為習知技術,故不在此贅述。該等學習屬性值包括該待分類學習者使用該數位學習平台系統的一時間總和、該待分類學習者閱讀章節佔全部章節之一比例值、該待分類學習者閱讀每一章節的一時間值、該待分類學習者重複閱讀每一章節的一次數值及該待分類學習者已上傳之作業佔全部作業的一比例值。First, as shown in step 21, the learner to be classified uses the user interface module 12 to input the sample of the learner to be classified having a plurality of learning attribute values, wherein the learner values are based on the learner to be classified. Obtained by an operation on a digital learning platform system (not shown), wherein the digital learning platform system presents a textbook of each chapter in a webpage manner and can be used by the learner to be uploaded and can record the to-be-categorized The learner's operation record, the establishment of the digital learning platform system is a conventional technology, and therefore will not be described here. The learning attribute values include a time sum of the learner's system using the digital learning platform, the learner's reading chapter of the to-be-classified student, and a time value of one of the chapters, and a time for the learner to read each chapter. The value, the value to be read by the learner to be repeated, and the value of the job that has been uploaded by the learner to be classified account for a percentage of the total job.
接著,如步驟22所示,該k最近鄰居計算模組13根據每一已分類學習者樣本的學習屬性值與該待分類學 習者樣本之學習屬性值,計算出該預定數目k的與該待分類學習者樣本距離最近之已分類學習者樣本,其中該等k個距離最近之已分類學習者樣本屬於M個學習社群。Next, as shown in step 22, the k nearest neighbor calculation module 13 learns the learning attribute value of each classified learner sample from the to-be-classified Calculating the learned attribute value of the learner sample, and calculating the predetermined number k of the classified learner samples closest to the learner sample to be classified, wherein the k consecutively classified learner samples belong to the M learning communities .
在本較佳實施例中,M值為3,且該等M個學習社群包括一緩慢型學習社群、一短暫型學習社群及一深入型學習社群。該緩慢型學習社群中的學習者花最長的時間在閱讀上,且有最多的重複點選每一章節的行為。該短暫型學習社群中的學習者閱讀時間最短,重複點選每一章節的行為也最少,且閱讀課程之章節的順序很不規律。該深入型學習社群中的學習者瀏覽課程的深度最深入,且閱讀課程之章節的順序很規律。In the preferred embodiment, the M value is 3, and the M learning communities include a slow learning community, a short-lived learning community, and an in-depth learning community. The learners in the slow learning community spend the longest time reading, and have the most repeated clicks on the behavior of each chapter. The learners in this ephemeral learning community have the shortest reading time, and the behavior of repeating each chapter is the least, and the order of reading the chapters of the course is very irregular. The depth of the course of the learner's browsing in the in-depth learning community is the most in-depth, and the order of the chapters in the course is very regular.
值得一提的是,該k最近鄰居計算模組13係採用下列公式求得該待分類學習者樣本P new
的學習屬性值與第i
個已分類學習者樣本L s_i
的學習屬性值之距離d
(P new
,L s_i
):
在本較佳實施例中,該預定數目k之值為5, 令(c i ,r i ) 代表在該等k個距離最近之已分類學習者樣本中,屬於第i 個學習社群c i 的數目有r i 個,i =1,2,3,則r 1 +r 2 +r 3 =5。In the preferred embodiment, the predetermined number k has a value of 5, such that (c i , r i ) represents the i- th learning community c i among the k consecutively classified learner samples. The number is r i , i =1, 2, 3, then r 1 + r 2 + r 3 = 5.
接著,如步驟23所示,該推薦模組14根據該等M個學習社群中之每一個學習社群所包含之該等k個已分類學習者樣本之數目r i ,排序出該待分類學習者樣本屬於每一學習社群的該優先順序推薦給該待分類學習者。其中該推薦模組14僅對該等M個學習社群中包含該等k個已分類學習者樣本之數目r i 不為零的學習社群進行排序,且該推薦模組14將該等M個學習社群中包含最多的該等k個已分類學習者樣本之學習社群指定為具有最高優先順序推薦給該待分類學習者。Then, as shown in step 23, the recommendation module 14 sorts the to-category according to the number r i of the k classified learner samples included in each of the M learning communities. The priority of the learner sample belonging to each learning community is recommended to the learner to be classified. Wherein the recommendation module 14 only those M learning community contains such a number k of samples classified learner r i is not zero learning community sort the recommender module 14 and the other M The learning community that contains the most of the k classified learner samples in the learning community is designated as having the highest priority recommendation to the learner to be classified.
綜上所述,藉由該k最近鄰居計算模組13根據每一已分類學習者樣本之學習屬性值與該待分類學習者樣本之學習屬性值計算出k個與該待分類學習者樣本距離最近之已分類學習者樣本,並藉由該推薦模組14排序出該待分類學習者樣本屬於每一學習社群的該優先順序而推薦給該待分類學習者,以達成在選擇學習社群時,不須耗費時間與精力去進行評估之功效,並降低因人為誤判而評估錯誤之風險,故確實能達成本發明之目的。In summary, the k nearest neighbor calculation module 13 calculates the distance between the k and the learner sample to be classified according to the learning attribute value of each classified learner sample and the learning attribute value of the learner sample to be classified. The recently-sorted learner samples are sorted out by the recommendation module 14 to the priority order of the learner group to be classified for each learning community, and recommended to the learner to be selected. At that time, it is not necessary to spend time and effort to carry out the evaluation, and to reduce the risk of misjudging due to human error, it is indeed possible to achieve the object of the present invention.
惟以上所述者,僅為本發明之較佳實施例而已,當不能以此限定本發明實施之範圍,即大凡依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾,皆仍屬本發明專利涵蓋之範圍內。The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the patent application scope and patent specification content of the present invention, All remain within the scope of the invention patent.
