【摘要】：本文利用文本挖掘方法分析了智能手環(huán)用戶評(píng)論中的熱點(diǎn)主題,以了解用戶對(duì)不同品牌智能手環(huán)關(guān)注點(diǎn)差異以及用戶關(guān)注主題隨時(shí)間的變化。首先,利用LDA模型對(duì)文本進(jìn)行主題分類,了解不同品牌用戶關(guān)注主題的排序;然后對(duì)不同時(shí)段各品牌的評(píng)論信息進(jìn)行分析,了解不同用戶群體對(duì)產(chǎn)品功能關(guān)注度的變化;最后分析用戶對(duì)不同品牌手環(huán)整體滿意度的差異,并結(jié)合評(píng)論文本信息分析用戶使用時(shí)長(zhǎng)與滿意度之間的關(guān)系。本研究發(fā)現(xiàn)對(duì)于所有品牌,用戶均關(guān)注產(chǎn)品功能和外觀,以及在使用中發(fā)現(xiàn)的產(chǎn)品問(wèn)題和感受,但是不同品牌關(guān)注主題排序各有差異。就用戶滿意度而言,隨著使用時(shí)間的增長(zhǎng),用戶對(duì)小米手環(huán)的滿意度日漸降低,而Fitbit和華為手環(huán)的用戶滿意度與使用時(shí)間呈正U形曲線。
[Abstract]:In this paper, a text mining method is used to analyze the hot topics in user reviews of smart bracelet, in order to understand the difference of user's attention to different brands of smart bracelet and the change of user's concern over time. The LDA model is used to classify the theme of the text to understand the ranking of the topics concerned by the users of different brands, and then to analyze the comments of different brands in different periods to understand the changes of the attention of different user groups to the function of the product.
