一種基于鏈接和語義關(guān)聯(lián)的知識圖示化方法
[Abstract]:Combing vast amounts of knowledge into a more acceptable form has been a difficult problem in the field of data analysis. Most traditional analytical methods summarize and describe the knowledge itself directly and conceptualize (conceptualization);. Some educational practices prove that it is easier to make a knowledge point accepted by human beings by graphing (schematization) from adjacent knowledge units. In the present classical computer knowledge representation method, knowledge representation mainly depends on manual finishing. In this paper, a method of using computer automation to realize knowledge schematization is proposed, which relies on Wikipedia concept topology to explore the relationship between concept and its adjacent concept, and an algorithm for automatically selecting the most correlated concept based on link is proposed. The semantic similarity between concepts is quantified by using the latest neural network model Word2Vec to further improve the association concept algorithm and improve the effect of knowledge representation. Experimental results show that the link based association concept algorithm has good accuracy and Word2Vec model can effectively improve the ranking effect of association concepts. The proposed method can accurately and effectively analyze the knowledge structure, comb the knowledge context, and provide practical and effective advice for researchers and learners.
