【摘要】：機(jī)電產(chǎn)品生產(chǎn)企業(yè)保持競爭優(yōu)勢的關(guān)鍵是向用戶提供優(yōu)質(zhì)、價廉的產(chǎn)品和服務(wù),并不斷提升用戶的滿意度,其關(guān)鍵問題是對產(chǎn)品進(jìn)行準(zhǔn)確的評價,并據(jù)此對產(chǎn)品進(jìn)行有效改進(jìn)。傳統(tǒng)的產(chǎn)品及服務(wù)評價一般由領(lǐng)域?qū)＜胰斯みM(jìn)行,但領(lǐng)域?qū)＜铱赡苋狈φ鎸嵉挠脩趔w驗,導(dǎo)致其對產(chǎn)品的評價并不被用戶真正認(rèn)可,最終達(dá)不到有效提升用戶滿意度的效果。隨著電子商務(wù)的迅猛發(fā)展,機(jī)電產(chǎn)品在線銷售已經(jīng)非常普及。電子商務(wù)網(wǎng)站一般都提供了用戶在線點評功能。大量用戶購買和使用產(chǎn)品后,所填寫的評價信息反映了用戶真實的產(chǎn)品體驗,能夠為機(jī)電產(chǎn)品提供高效、客觀的評價信息。因此本文提出基于在線點評挖掘的機(jī)電產(chǎn)品評價方法,以電子商務(wù)網(wǎng)站上的用戶在線點評數(shù)據(jù)作為產(chǎn)品評價的主要信息來源,通過對大量點評數(shù)據(jù)的挖掘來對產(chǎn)品進(jìn)行客觀和真實的評價,以解決專家評價存在缺乏真實的用戶體驗問題。本文的主要研究內(nèi)容包括：1)在確定點評數(shù)據(jù)的來源和分析其特點的基礎(chǔ)上,設(shè)計面向在線點評的網(wǎng)絡(luò)爬蟲來獲取用戶點評數(shù)據(jù),并對其進(jìn)行預(yù)處理,以滿足評價指標(biāo)體系優(yōu)化和用戶評價識別研究的需求。2)設(shè)計面向在線點評的評價指標(biāo)體系；基于用戶知識提出評價指標(biāo)體系優(yōu)化方法；基于評價指標(biāo)體系提出模糊模式匹配模板方法識別在線點評中的用戶評價。3)基于模糊綜合評價,提出機(jī)電產(chǎn)品的評價框架；提出模糊綜合評價改進(jìn)方法以實現(xiàn)從不可信的在線點評數(shù)據(jù)中獲取可信的評價結(jié)果。4)針對模糊綜合評價方法缺乏對評價結(jié)果的具體解釋的問題,提出基于模糊認(rèn)知圖的產(chǎn)品個性化評價模型,實現(xiàn)了對評價結(jié)果的具體解釋,以及更加經(jīng)濟(jì)的可替換改進(jìn)評價指標(biāo)的推薦,以提升用戶滿意度。本文提出的基于在線點評的產(chǎn)品評價方法拓展了產(chǎn)品評價的廣度和深度,對產(chǎn)品評價有一定的理論指導(dǎo)意義,同時在幫助企業(yè)提升產(chǎn)品的用戶滿意度和市場競爭力方面有一定的實際意義。
[Abstract]:The key to maintain the competitive advantage of mechanical and electrical products manufacturing enterprises is to provide customers with high-quality, inexpensive products and services, and to continuously improve their satisfaction. The key problem is to evaluate the products accurately and improve the products accordingly. Traditional product and service evaluation is generally carried out manually by domain experts, but domain experts may lack real user experience, which leads to product evaluation is not really recognized by users, and ultimately it can not effectively improve the effect of user satisfaction. With the rapid development of e-commerce, mechanical and electrical products online sales have been very popular. E-commerce websites generally provide users with online comment function. After a large number of users purchase and use the products, the evaluation information filled in reflects the real product experience of the users, and can provide efficient and objective evaluation information for mechanical and electrical products. Therefore, this paper puts forward an evaluation method of electromechanical products based on online comment mining, which takes the online comment data of electronic commerce website as the main information source of product evaluation. In order to solve the problem of lack of real user experience in expert evaluation, the product is evaluated objectively and truthfully by mining a lot of comment data. The main research contents of this paper are as follows: 1) on the basis of determining the source and analyzing the characteristics of the data, a web crawler oriented to online review is designed to obtain the data and preprocess it. In order to meet the needs of the optimization of evaluation index system and the research of user evaluation identification. 2) to design an evaluation index system oriented to online evaluation, and to propose an optimization method for evaluation index system based on user knowledge. Based on the evaluation index system, the fuzzy pattern matching template method is proposed to identify the user evaluation in the online evaluation. 3) based on the fuzzy comprehensive evaluation, the evaluation framework of mechanical and electrical products is proposed. An improved fuzzy comprehensive evaluation method is proposed to obtain credible evaluation results from untrusted online evaluation data. 4) in view of the lack of concrete explanation of the fuzzy comprehensive evaluation method, A product individuation evaluation model based on fuzzy cognitive map is proposed, which realizes the concrete explanation of evaluation results and the more economical recommendation of alternative and improved evaluation index, in order to improve user satisfaction. The product evaluation method proposed in this paper based on online evaluation expands the breadth and depth of product evaluation, and has certain theoretical significance for product evaluation. At the same time, it has certain practical significance in helping enterprises to enhance customer satisfaction and market competitiveness.
