【摘要】：【目的】更好地反映MOOC論壇參與者的活躍水平以及論壇主題的質(zhì)量,以提高學(xué)員的論壇參與度,發(fā)揮MOOC社會效應(yīng)�！痉椒ā刻岢龀W(wǎng)絡(luò)下"迭代超中心度"概念和算法,通過多次迭代,直至收斂,將整個網(wǎng)絡(luò)的節(jié)點考慮在內(nèi),以更全面地反映出不同節(jié)點的重要性與影響力�！窘Y(jié)果】傳統(tǒng)網(wǎng)絡(luò)指標(biāo)揭示的信息有限,點度小的節(jié)點,其重要性與影響力可能大;點度相同的節(jié)點,重要性與影響力也會不同。迭代超中心度全面衡量節(jié)點的重要性,在MOOC中更能反映出節(jié)點推動知識流動的能力�！揪窒蕖繑�(shù)據(jù)量比較少,只對一門課程進(jìn)行分析,沒有從更多的超網(wǎng)絡(luò)指標(biāo)進(jìn)行分析�！窘Y(jié)論】"迭代超中心度"可以揭示出論壇參與者的活躍水平以及論壇主題的質(zhì)量,可以作為一種改進(jìn)論壇設(shè)置的評價指標(biāo)。
[Abstract]:[objective] to better reflect the active level of MOOC forum participants and the quality of forum topics, so as to increase participants' participation in the forum and bring into play the social effects of MOOC. [methods] the concept and algorithm of "iterative hypercenter" in hypernetwork are proposed. After several iterations until convergence, the nodes of the whole network are taken into account to reflect more comprehensively the importance and influence of different nodes. [results] the traditional network indicators reveal nodes with limited information and small vertices. Its importance and influence may be great; the nodes with the same vertex will be different in importance and influence. Iterative hypercentricity is a comprehensive measure of the importance of nodes. The ability of nodes to drive knowledge flows is better reflected in MOOC. [limitations] the amount of data is relatively small and only one course is analyzed. [conclusion] "iterative hypercentricity" can reveal the active level of forum participants and the quality of forum topics, and can be used as an evaluation index to improve forum setting.
