【摘要】：隨著信息化時代的到來,教育信息化也在大力建設(shè)中。專業(yè)作為高校人才培養(yǎng)的載體,是高校提高教學(xué)質(zhì)量的立足點(diǎn),它的信息化建設(shè)顯得迫切而重要。本課題以電子信息科學(xué)與技術(shù)專業(yè)為例,介紹專業(yè)信息化建設(shè)目標(biāo)：以師資建設(shè)為基礎(chǔ),以課程與教學(xué)資源建設(shè)為核心,以專業(yè)主頁為載體和工具。在專業(yè)主頁建設(shè)中,存在以下幾個問題,專業(yè)領(lǐng)域資源形式多樣,包括結(jié)構(gòu)化和非結(jié)構(gòu)化的數(shù)據(jù),數(shù)據(jù)內(nèi)部信息無法交流；專業(yè)課程內(nèi)部很多學(xué)習(xí)規(guī)則、經(jīng)驗(yàn)方法缺少歸納、總結(jié),學(xué)生無法利用這些知識；專業(yè)主頁不應(yīng)僅是一個資源呈現(xiàn)、缺少交互的平臺,沒有用戶參與、互動及反饋,不利于專業(yè)主頁知識體系的完善、發(fā)展,同時專業(yè)主頁中的不同用戶的興趣、關(guān)注點(diǎn)不一樣,需要系統(tǒng)為不同用戶提供個性化的服務(wù)。 本文根據(jù)專業(yè)主頁建設(shè)中遇到的問題,進(jìn)行研究。研究點(diǎn)主要分為以下三點(diǎn),第一,設(shè)計了基于語義的專業(yè)知識體系的構(gòu)建方案,并在此基礎(chǔ)上設(shè)計實(shí)現(xiàn)搜索與推薦系統(tǒng)；第二,設(shè)計一套交互式學(xué)習(xí)模型,并探索其在專業(yè)主頁中的應(yīng)用,完善專業(yè)課程知識體系的構(gòu)建,實(shí)現(xiàn)個性化的推薦。第三,基于以上兩點(diǎn)的研究,設(shè)計并實(shí)現(xiàn)具有語義推薦功能的交互式專業(yè)主頁系統(tǒng)。 第一部分,基于語義的專業(yè)知識體系構(gòu)建及搜索推薦機(jī)制的研究。我們利用基于語義的信息整合理論及其相關(guān)技術(shù),建立了一套基于語義信息整合的專業(yè)知識體系模型,通過本體構(gòu)建,包括資源元數(shù)據(jù)本體、專業(yè)資源內(nèi)容本體和專業(yè)學(xué)科輔助學(xué)習(xí)本體,實(shí)現(xiàn)對專業(yè)內(nèi)資源、知識體系的整合,以及對課程學(xué)習(xí)中學(xué)習(xí)規(guī)則、經(jīng)驗(yàn)的歸納、總結(jié)。同時,在專業(yè)知識體系的構(gòu)建基礎(chǔ)上,設(shè)計語義檢索模型,實(shí)現(xiàn)對知識概念及其之間關(guān)系進(jìn)行語義層面的搜索。本課題使用Jena推理機(jī),設(shè)計一套合理的推理規(guī)則,實(shí)現(xiàn)專業(yè)主頁中資源整合,并能為用戶提供專業(yè)知識推薦。 第二部分,專業(yè)交互式學(xué)習(xí)模型研究。本課題主要研究交互式學(xué)習(xí)模型中的交互式策略及交互策略在專業(yè)主頁中的應(yīng)用。本課題設(shè)計了被動式交互學(xué)習(xí)及主動式交互學(xué)習(xí)兩種策略。被動式交互學(xué)習(xí)是通過系統(tǒng)獲取用戶日志的方式,主動記錄用戶的對專業(yè)主頁的使用及學(xué)習(xí)情況；主動式交互策略我們設(shè)計了一套用戶文字輸入的方式,主動提供自己對專業(yè)知識學(xué)習(xí)的認(rèn)識。系統(tǒng)通過這兩種策略獲取用戶個性化的學(xué)習(xí)需求,記錄用戶的知識點(diǎn)的學(xué)習(xí)目標(biāo)、學(xué)習(xí)軌跡、學(xué)習(xí)完成情況等信息,并通過分析這些信息,完善之前的專業(yè)知識體系構(gòu)建,并可以提供更個性化的推薦等。實(shí)現(xiàn)了專業(yè)主頁的交互性。 第三部分,在前期利用基于語義信息整合理論構(gòu)建專業(yè)知識體系和交互式學(xué)習(xí)模型設(shè)計的基礎(chǔ)之上,進(jìn)行具有語義搜索推薦功能的交互式專業(yè)主頁系統(tǒng)的設(shè)計,包括系統(tǒng)需求分析、系統(tǒng)功能設(shè)計、數(shù)據(jù)庫設(shè)計和頁面原型設(shè)計,并采用MVC模型中Spring框架,實(shí)現(xiàn)一個具有語義搜索功能和便于交互的專業(yè)主頁系統(tǒng)。
[Abstract]:With the advent of the information era, education information also vigorously construction. As the carrier of professional personnel training in Colleges and universities, is to improve the quality of teaching in Colleges and Universities Based on informatization construction, it is urgent and important. This topic in electronic information science and technology major as an example, introduces the professional information construction goal: to construction of teachers as the basis, the curriculum and teaching resources construction as the core, to the professional home as the carrier and tools. In the professional home building, there are several problems, professional resources in various forms, including structured and unstructured data, internal information data can not communicate; professional courses many learning rules, lack of experience for induction, summary, students cannot use this knowledge; professional home is not only a lack of resources, interactive platform, no user participation, interaction and feedback, is not conducive to the professional The perfection and development of home page knowledge system, at the same time, the interest and concerns of different users in professional homepage are different. Different systems need to provide personalized service for different users.
This paper according to the encountered problems in the construction of professional website,. Research is mainly divided into the following three points. First, designing the professional knowledge system based on semantic, and on the basis of the design and implementation of search and recommendation system; second, design a set of interactive learning model, and explore its application in the professional home page the construction of perfect knowledge system of professional courses, the realization of personalized recommendation. Third, based on the above research, the design and implementation of interactive professional homepage system semantic recommendation function.
The first part of the construction and search recommendation mechanism based on semantic knowledge system. We use the semantic information integration theory and related technology based on the established based on the professional knowledge system model of semantic information integration, through the ontology construction, including metadata ontology, professional resources and professional disciplines assisted learning content ontology ontology, realize on the professional resources, integration of knowledge, and the learning rules of the course of study, summed up the experience of induction. At the same time, in the foundation of professional knowledge system, design the semantic retrieval model, realizes the semantic level of search and the relationship between the concept of knowledge. This paper use the Jena inference engine, design a set of reasonable inference rules, to achieve the integration of resources professional homepage, and can provide professional knowledge recommendation for users.
The second part, the research model of professional interactive learning. This paper mainly studies the application of interactive strategy and interactive strategy of interactive learning in the model of professional home. This paper designs the passive interactive learning and interactive learning strategies. Two kinds of active passive interactive learning is to get the user logs through the system, users of professional active record home use and learning; active interactive strategy we designed a set of user text input mode, take the initiative to provide understanding of their learning of professional knowledge. The system gets the user personalized through the two kinds of learning strategies needs to record the user's knowledge of the learning objectives, learning path, learning to complete information, and by analyzing these information, construction of professional knowledge system before, and can provide a more personalized recommendation. The professional page Interactivity.
The third part, in the early use of construction based on professional knowledge system and the design of interactive learning model of semantic information integration theory, the design of professional interactive homepage system with semantic search recommendation function, including system requirements analysis, system function design, database design and prototype design, and uses the Spring framework of MVC model, to achieve a a professional home system with semantic search function and facilitate the interaction.
