【摘要】：電子商務(wù)網(wǎng)站中,海量無(wú)序的用戶評(píng)論可能導(dǎo)致消費(fèi)者客戶"迷失"其中,無(wú)法識(shí)別評(píng)論的可信和真假。針對(duì)這個(gè)問題,提出了一種根據(jù)用戶評(píng)論的可信度對(duì)其重新排序的方法。首先,針對(duì)網(wǎng)站商品廣告信息,關(guān)注在線用戶評(píng)論內(nèi)容是否和商品功能屬性密切相關(guān),設(shè)計(jì)了基于HTML腳本格式的購(gòu)物網(wǎng)站中商品關(guān)鍵特征提取算法,給出了基于自然語(yǔ)言處理的用戶評(píng)論特征詞提取方法;然后,利用詞語(yǔ)相似度來分析商品特征和用戶評(píng)論內(nèi)容之間的關(guān)聯(lián)度,提出了購(gòu)物客戶評(píng)論的可信度計(jì)算方法;最后,通過實(shí)例分析,實(shí)現(xiàn)了大量購(gòu)物客戶評(píng)論的可信排序,使得用戶無(wú)須瀏覽全部或者大部分之后就能判斷哪些評(píng)價(jià)可以信任或者具有實(shí)際的參考價(jià)值,降低了信息搜索成本,提高了決策效率。
[Abstract]:In e-commerce websites, the mass of disordered user comments may cause consumers to "lose" them, and can not identify the credibility and authenticity of the comments. In order to solve this problem, this paper proposes a method to reorder user comments according to their credibility. Firstly, focusing on whether the online user comment content is closely related to the product function attribute, this paper designs the key feature extraction algorithm of the shopping website based on HTML script format, aiming at the product advertisement information of the website. The method of extracting user comment feature words based on natural language processing is presented. Then, using the similarity degree of words to analyze the correlation between the characteristics of goods and the content of user's comments, and put forward the method of calculating the credibility of shopping customers' comments. Finally, through the analysis of examples, the trusted ranking of a large number of shopping customers' comments is realized, so that users can judge which evaluation can be trusted or have practical reference value without having to browse all or most of them. It reduces the cost of information search and improves the efficiency of decision-making.
