semantic distance
解釋
語義距離-
Abide by the principles of " to first realize that different ones have the same cognizance about the same terms and then to realize information sharing ", we use ontology to describe the critical terms in distance learning and to structuralize and to provide equivalence criteria, and at the same time it can effectively reduce the semantic conflicts and facilitate the interoperability among different data sources
由於教育系統的多元化，使得不同的系統對教育詞匯的定義往往產生分歧，針對這種現狀，我們本著先實現共知，后實現共享的原則，運用本體描述領域中的關鍵術語，建立領域詞匯表，為信息共享創造條件。 -
First, the question answering system calculates semantic similarity by using distance between words in semantic tree and the height of semantic tree, then this system uses semantic similarity between words and the weight of word to calculate semantic similarity between users ' questions and questions in answer database
首先，利用語義樹中詞語間的距離和語義樹的高度來計算詞語間的語義相似度，然後利用詞語間的語義相似度和詞語的權重進一步計算用戶問題與答案庫中問題間的語義相似度。 -
This feature perfectly combine the frequency in acoustics level and the temperament in music semantic level, we use the cosine distance of this feature to represent the similarity of two music clips, then we design a group of algorithms that is inspired from the thought of edit distance and dynamic programming. they segment the feature vectors into groups at first, then through group similarity match, group recurrent detect, merge recurrent group and structure label joined algorithms to complete the music structure label task. because this is a really new field of research and no good method of evaluation had been finding, we propose a new evaluation method and the results of the experiments show that it is a good method
然後設計了一組源於編輯距離和動態規劃思想的音樂結構分析演算法，首先將特徵向量分組，然後經過組相似匹配、組重現檢測、重現組歸並和自動標注四個前後銜接的環節實現了音樂結構的自動標注，較好地實現了將音頻形式的音樂自動標注為表示音樂結構的三元組列表形式，由於這是一個新的領域，目前還沒有比較好的量化評價方法，本文提出一種新的評價方法，並用它來評價結構分析的結果，取得了較好的效果。 -

It is proposed to use the semantic distance for estimating the matching degree between a service and a user request. four types of semantic distances are defined and four algorithms are implemented respectively to calculate them. experimental results show that the proposed semantic matchmaker significantly outperforms the keyword - based baseline method
因此，為了比較準確的區分不同服務與用戶請求之間的匹配程度，本文首先提出了一個基線服務匹配方法，利用關鍵字匹配將每個服務與用戶請求之間的匹配程度進行量化表示，並按照匹配程度對服務進行排序，便於用戶選擇最合適的服務。
