基于改進協同過濾算法的高校思政課程推薦系統研究

張凡 劉國營

摘 要： 針對目前高校思政教育課程設置存在的形式單一、針對性不強、缺乏協同效應、無法形成個性化協同育人機制等問題，開發了一款基于改進協同過濾技術的高校思政課程推薦系統，采用基于混合的協同過濾改進算法，通過引入基于用戶興趣時效性變化的逐步遺忘曲線，較好的解決了傳統協同過濾算法存在的效率低、適應性弱、排新性等弊端。開發了對應的高校思政課程推薦系統，通過實際驗證得知，該系統運行穩定，功能完整，具有較強的實用性、魯棒性，對于營造師生協同共贏、形式多樣、個性創新的高校思政教育氛圍具有積極意義，符合新形勢下高校思政教育“澆花澆根，教人教心”的立體育人模式趨勢。

Abstract： Aiming at the problems of single form， lack of pertinence， lack of synergy effect and incapability of forming personalized collaborative education mechanism in ideological and political education curriculum in colleges and universities， a recommendation system of ideological and political education curriculum in colleges and universities is developedbased on improved collaborative filtering technology. An improved algorithm of collaborative filtering based on hybrid is adopted， and a gradual forgetting tune based on the time-varying interests of users is introduced. The line can solve the disadvantages of traditional collaborative filtering algorithm， such as low efficiency， weak adaptability and novelty. A corresponding recommendation system for ideological and political courses in colleges and universities has been developed. Through practical verification， it is known that the system is stable， functional and complete， with strong practicability and robustness. It has positive significance for creating a win-win， diverse and innovative atmosphere for ideological and political education in colleges and universities. It is in line with the new situation that ideological and political education in Colleges and universities “watering flowers， watering roots， teaching people and teaching hearts” trend of three-dimensional educational model.

Key words： collaborative filtering algorithm; algorithmic optimization; ideological and political education; gradual forgetting curve; collaborative education

思政教育課程作為開展高校思想政治工作的主渠道、主陣地，是實踐高校育人機制的重要途徑，也是高校理論課體系的重要組成部分，貫穿高等教育教學全過程，是高校培養社會主義建設者和接班人的重要制度載體[1]，在強化高校在校生的價值引領、加強愛國奉獻主旋律宣傳教育，建立全員全過程全方位育人機制等領域發揮著基礎性作用。習近平總書記在全國高校思想政治工作會議上的重要講話從全局和戰略高度指出了高校思政教育的若干重大問題，具有很強的政治性、思想性、針對性和可操作性，是新形勢下開展高校思想政治工作的綱領性文件[2]。……
