【摘要】：隨著移動(dòng)通訊技術(shù)的飛速發(fā)展以及移動(dòng)智能終端的普及應(yīng)用,互聯(lián)網(wǎng)隨身化、便攜化的趨勢(shì)越發(fā)明顯,傳統(tǒng)的互聯(lián)網(wǎng)搜索技術(shù)難以滿(mǎn)足移動(dòng)環(huán)境中不同背景、不同目的、不同位置以及不同時(shí)期的個(gè)性化搜索需求。同時(shí),移動(dòng)互聯(lián)網(wǎng)服務(wù)和信息內(nèi)容的迅速增長(zhǎng)帶來(lái)“移動(dòng)信息過(guò)載”問(wèn)題,如何根據(jù)用戶(hù)當(dāng)前所處地理位置,為之提供符合其興趣特征和意圖的個(gè)性化搜索結(jié)果,滿(mǎn)足用戶(hù)隨時(shí)、隨地、隨身的個(gè)性化服務(wù)需求是一個(gè)廣闊應(yīng)用價(jià)值的研究課題。 本課題來(lái)源于某移動(dòng)互聯(lián)網(wǎng)創(chuàng)業(yè)項(xiàng)目,在借鑒已有個(gè)性化搜索研究成果的基礎(chǔ)上,結(jié)合基于位置的手機(jī)美食導(dǎo)航應(yīng)用需求展開(kāi)理論和應(yīng)用研究。論文主要工作包括： 1.綜述了搜索引擎、基于位置的服務(wù)以及個(gè)性化搜索相關(guān)技術(shù)原理及工作流程,為后續(xù)用戶(hù)興趣建模和算法設(shè)計(jì)奠定基礎(chǔ)。 2.針對(duì)移動(dòng)環(huán)境下的的用戶(hù)特點(diǎn)對(duì)用戶(hù)行為進(jìn)行建模,對(duì)用戶(hù)行為信息的采集、用戶(hù)參與度評(píng)估、用戶(hù)行為模型表達(dá)以及模型更新策略展開(kāi)分析和討論,然后基于此設(shè)計(jì)相應(yīng)的用戶(hù)興趣模型。 3.結(jié)合用戶(hù)興趣模型設(shè)計(jì)基于位置服務(wù)的個(gè)性化美食搜索算法,一是通過(guò)個(gè)性化的關(guān)鍵詞擴(kuò)展查詢(xún)優(yōu)化查詢(xún)結(jié)果,二是結(jié)合用戶(hù)當(dāng)前位置以及用戶(hù)行為軌跡對(duì)查詢(xún)結(jié)果進(jìn)行優(yōu)化排序。同時(shí),結(jié)合直接反饋機(jī)制和間接反饋機(jī)制對(duì)用戶(hù)體驗(yàn)度進(jìn)行評(píng)價(jià)。 4.基于前述用戶(hù)興趣模型和個(gè)性化美食搜索算法,設(shè)計(jì)并實(shí)現(xiàn)了一個(gè)手機(jī)美食導(dǎo)航軟件系統(tǒng),該系統(tǒng)可結(jié)合用戶(hù)當(dāng)前地理位置及用戶(hù)偏好,搜索并推薦相應(yīng)美食信息。系統(tǒng)測(cè)試和實(shí)驗(yàn)結(jié)果表明,本文所提用戶(hù)興趣模型及個(gè)性化美食算法可獲得較好的推薦結(jié)果及用戶(hù)體驗(yàn)度。
[Abstract]:With the rapid development of mobile communication technology and the popularization and application of mobile intelligent terminals, the trend of Internet carry-on and portability becomes more and more obvious. The traditional Internet search technology is difficult to meet the different background and purpose in mobile environment. At the same time, the rapid growth of mobile Internet services and information content brings "mobile information overload" problem, how to according to the current geographical location of users, It is a research topic with wide application value to provide personalized search results that accord with its interest features and intentions, and to meet the needs of personalized services of users at any time, anywhere and with them. This topic comes from a mobile Internet startup project. On the basis of the existing research results of personalized search, combined with the location of mobile phone food navigation application requirements to carry out the theory and application research. The main work of this paper is as follows:. 1. The principles and workflow of search engine, location-based service and personalized search technology are summarized, which will lay the foundation for user interest modeling and algorithm design. 2. Modeling the user behavior in the mobile environment, analyzing and discussing the collection of user behavior information, the evaluation of user participation, the expression of user behavior model and the strategy of model updating. Then the corresponding user interest model is designed based on this. 3. The personalized food search algorithm based on location service is designed based on user interest model. The second is to optimize the query results by combining the user's current location and user behavior trajectory. At the same time, the user experience is evaluated by direct feedback mechanism and indirect feedback mechanism. 4. Based on the above user interest model and personalized food search algorithm, a mobile food navigation software system is designed and implemented. The system can combine the users' current geographical location and user preferences. The system tests and experimental results show that the proposed user interest model and personalized food algorithm can obtain better recommended results and user experience.
