【摘要】：[目的/意義]針對(duì)關(guān)鍵詞共現(xiàn)方法識(shí)別領(lǐng)域研究熱點(diǎn)過(guò)程中數(shù)據(jù)清洗進(jìn)行理論研究與探索,以輔助科研工作者準(zhǔn)確識(shí)別領(lǐng)域研究熱點(diǎn)。[方法/過(guò)程]在文獻(xiàn)調(diào)研的基礎(chǔ)上,闡述數(shù)據(jù)清洗的定義和對(duì)象,并分析臟數(shù)據(jù)產(chǎn)生的原因和影響,進(jìn)而制定數(shù)據(jù)清洗的步驟和方案,并采用實(shí)證研究方法對(duì)數(shù)據(jù)清洗的效果和方案的可行性進(jìn)行驗(yàn)證。[結(jié)果/結(jié)論]研究結(jié)果表明該數(shù)據(jù)清洗方案能夠提高研究熱點(diǎn)識(shí)別的準(zhǔn)確性,從而證明了該方案的可行性。
[Abstract]:[Objective / significance] to study and explore the data cleaning in the research hot spot of keyword co-occurrence method in order to assist scientific research workers to identify the research hotspot accurately. [Methods on the basis of literature investigation, the definition and object of data cleaning were expounded, and the causes and effects of dirty data were analyzed, and then the steps and schemes of data cleaning were worked out. The effect of data cleaning and the feasibility of the scheme are verified by the empirical research method. [Results / conclusion] the results show that the data cleaning scheme can improve the accuracy of hot spot identification, which proves the feasibility of the scheme.

【正文快照】： 研究熱點(diǎn)是指在一定時(shí)期內(nèi)某一研究領(lǐng)域中,研究人員所共同關(guān)注的焦點(diǎn)[1]。準(zhǔn)確識(shí)別出領(lǐng)域研究熱點(diǎn)對(duì)把握該領(lǐng)域的研究發(fā)展趨勢(shì)和研究方向具有重要意義。目前學(xué)者們主要運(yùn)用關(guān)鍵詞共現(xiàn)方法對(duì)該領(lǐng)域的研究熱點(diǎn)進(jìn)行識(shí)別[1-3]。從筆者掌握的文獻(xiàn)來(lái)看,目前的研究多是注重研究熱點(diǎn)識(shí)，
