【摘要】：本文利用網(wǎng)絡(luò)爬蟲技術(shù)對(duì)萬方知識(shí)平臺(tái)的科技論文大數(shù)據(jù)進(jìn)行抓取,基于社會(huì)網(wǎng)絡(luò)方法構(gòu)建了作者合作網(wǎng)絡(luò)、科研機(jī)構(gòu)合作網(wǎng)絡(luò)和地區(qū)合作網(wǎng)絡(luò),對(duì)網(wǎng)絡(luò)的基本屬性、關(guān)鍵節(jié)點(diǎn)進(jìn)行了個(gè)性化分析。研究發(fā)現(xiàn):中國科技創(chuàng)新論文穩(wěn)步上升并呈現(xiàn)空間集聚性,"農(nóng)業(yè)"、"大學(xué)生"等關(guān)鍵詞成為研究熱點(diǎn),產(chǎn)學(xué)研合作不斷加深,但從區(qū)域看,由東向西區(qū)域協(xié)同創(chuàng)新能力逐漸減弱,核心作者間的信息分享與協(xié)同創(chuàng)新較少,處于同一地區(qū)、具有相同經(jīng)營范圍或研究方向的機(jī)構(gòu)單位之間更容易展開合作。
[Abstract]:This paper makes use of the technology of web crawler to grasp the scientific and technological paper big data of Wanfang knowledge platform. Based on the method of social network, the author's cooperative network, the cooperative network of scientific research institutions and the regional cooperative network are constructed, and the basic properties of the network are also discussed.The personalization analysis of the key nodes is carried out.It is found that Chinese scientific and technological innovation papers are rising steadily and present spatial agglomeration. Key words such as "agriculture" and "college students" have become the focus of research. The cooperation between industry, education and research has been deepened, but from the regional point of view, the ability of collaborative innovation from east to west has gradually weakened.There is less information sharing and collaborative innovation among core authors, and it is easier to cooperate among institutions with the same business scope or research direction in the same area.
