【摘要】:隨著互聯(lián)網(wǎng)應(yīng)用在商業(yè)領(lǐng)域的快速普及,用戶(hù)的需求體驗(yàn)成為互聯(lián)網(wǎng)發(fā)展的驅(qū)動(dòng)力。以電子商務(wù)系統(tǒng)為代表的社交網(wǎng)絡(luò)不斷發(fā)生新的變化。電子商務(wù)系統(tǒng)在為用戶(hù)提供越來(lái)越多選擇的同時(shí),其結(jié)構(gòu)也變得更加復(fù)雜,用戶(hù)經(jīng)常會(huì)迷失在大量的商品信息空間中,無(wú)法順利找到自己需要的商品。電子商務(wù)推薦系統(tǒng)直接與用戶(hù)交互,模擬商店銷(xiāo)售人員向用戶(hù)提供商品推薦服務(wù),幫助用戶(hù)找到所需商品,從而順利完成購(gòu)買(mǎi)過(guò)程。隨著電子商務(wù)系統(tǒng)規(guī)模的進(jìn)一步擴(kuò)大,電子商務(wù)推薦系統(tǒng)也在飛速的發(fā)展。目前主流的電子商務(wù)推薦系統(tǒng)有:基于協(xié)同過(guò)濾算法的電子商務(wù)推薦系統(tǒng);基于用戶(hù)統(tǒng)計(jì)算法的電子商務(wù)推薦系統(tǒng);基于知識(shí)發(fā)現(xiàn)算法電子商務(wù)推薦系統(tǒng)和基于效用的電子商務(wù)推薦系統(tǒng)。但這些推薦系統(tǒng)存在著各自的局限性,因此在電子商務(wù)推薦系統(tǒng)中,消費(fèi)者意圖的識(shí)別承擔(dān)著越來(lái)越重要的作用。消費(fèi)者意圖的識(shí)別對(duì)于電子商務(wù)商品推薦、熱點(diǎn)引流商品選取、網(wǎng)站布局以及鏈接的設(shè)置有至關(guān)重要的影響。目前的大部分研究都認(rèn)為意圖是靜態(tài)的,即特定的意圖是伴隨著特定的環(huán)境的,因而在特定的環(huán)境下有特定的變化。然而,消費(fèi)者在電子商務(wù)活動(dòng)中訪(fǎng)問(wèn)和選購(gòu)商品時(shí)的不確定性告訴我們消費(fèi)者的意圖可表現(xiàn)為多種形態(tài),并且是多階段發(fā)展的。因此,本研究用蟻群算法中的螞蟻來(lái)表示消費(fèi)者,通過(guò)螞蟻對(duì)信息素的趨好性來(lái)模擬消費(fèi)者的瀏覽、收藏、加入購(gòu)物車(chē)和購(gòu)買(mǎi)行為的意圖。因?yàn)橄M(fèi)者意圖為表現(xiàn)為商品的客觀(guān)屬性與消費(fèi)者的主觀(guān)感受的匹配,所以,我們將信息素表示為商品的客觀(guān)屬性和消費(fèi)者感知能力的內(nèi)積,其值即為表示消費(fèi)者意圖的信息素的濃度。我們把這種信息素稱(chēng)為感知信息素,用來(lái)表示消費(fèi)者意圖。這樣就可以通過(guò)蟻群算法來(lái)呈現(xiàn)消費(fèi)者意圖的動(dòng)態(tài)性和不確定性。然后,本研究通過(guò)NetLogo仿真實(shí)驗(yàn)以獲取數(shù)據(jù),再以神經(jīng)網(wǎng)絡(luò)來(lái)識(shí)別和驗(yàn)證消費(fèi)者的瀏覽、收藏、加入購(gòu)物車(chē)和購(gòu)買(mǎi)意圖。實(shí)驗(yàn)結(jié)果表明:在95%的顯著性水平下,本研究所提出的模型將意圖預(yù)測(cè)的準(zhǔn)確度從48%提升到67%左右,可以更加準(zhǔn)確的向用戶(hù)推薦商品,具有良好的現(xiàn)實(shí)意義。
[Abstract]:With the rapid popularity of Internet applications in the business field, user needs experience has become the driving force of the development of the Internet. Social networks, represented by e-commerce systems, are constantly undergoing new changes. Electronic commerce system provides more and more choices for users at the same time, its structure becomes more complex, users often lose in a large number of commodity information space, can not find their own needs of goods. The E-commerce recommendation system directly interacts with the user, simulates the shop salesperson to provide the product recommendation service to the user, helps the user to find the needed product, thus completes the purchase process smoothly. With the further expansion of e-commerce system, e-commerce recommendation system is also developing rapidly. At present, the main E-commerce recommendation system includes: E-commerce recommendation system based on collaborative filtering algorithm, e-commerce recommendation system based on user statistics algorithm, and electronic commerce recommendation system based on user statistics algorithm. E-commerce recommendation system based on knowledge discovery algorithm and utility-based e-commerce recommendation system. However, these recommendation systems have their own limitations, so the recognition of consumer intention plays an increasingly important role in e-commerce recommendation systems. The identification of consumer intention is of great importance to the recommendation of e-commerce products, the selection of hot spots, the layout of websites and the setting of links. Most of the current studies suggest that the intention is static, that is, the specific intention is accompanied by the specific environment, so there is a specific change in the specific environment. However, the uncertainty when consumers visit and choose goods in e-commerce activities tells us that the intention of consumers can be expressed in a variety of forms, and is multi-stage development. Therefore, the ants in ant colony algorithm are used to represent consumers, and the intention of consumers to browse, collect, add shopping cart and purchase behavior is simulated by ants' readability to pheromone. Because consumers intend to match the objective attributes of commodities with the subjective feelings of consumers, we express pheromones as the inner product of the objective attributes of commodities and the perception ability of consumers. Its value is the concentration of pheromone that represents the intention of the consumer. We call this pheromone a perceptual pheromone, which is used to express consumer intention. In this way, ant colony algorithm can be used to show the dynamic and uncertainty of consumer intention. Then, through the NetLogo simulation experiment to obtain the data, and then the neural network to identify and verify the browsing, collecting, adding shopping cart and purchase intention. The experimental results show that the proposed model can improve the accuracy of intention prediction from 48% to 67% under the significance level of 95%. It can recommend products to users more accurately and has good practical significance.
