【摘要】：為幫助科研人員從海量的網(wǎng)絡科技信息中發(fā)現(xiàn)高情報價值的信息資源,提高其網(wǎng)絡信息的利用效率,本文通過對知識對象屬性及對象間相互關(guān)系進行計算,提出網(wǎng)絡科技信息情報價值判斷的新思路,具體包括三個部分:基于對象及其行為構(gòu)建情報關(guān)注模型,對科研人員的先驗證知識進行結(jié)構(gòu)化描述;基于對象網(wǎng)格實現(xiàn)網(wǎng)絡科技信息中重要對象及其行為的識別,對網(wǎng)絡資源中蘊含的重要情報線索進行揭示;通過計算二者的匹配度對網(wǎng)絡資源的情報價值進行判斷。選取美國能源部網(wǎng)站發(fā)布的科技信息作為實驗數(shù)據(jù),驗證了知識對象及對象間關(guān)系在情報價值判斷中的重要作用。
[Abstract]:In order to help researchers find information resources with high information value from massive network scientific and technological information and improve the utilization efficiency of network information, this paper calculates the attributes of knowledge objects and their interrelationships. This paper puts forward a new way to judge the value of network scientific and technological information, which includes three parts: constructing the information concern model based on object and its behavior, and structurally describing the scientific researchers' first verification knowledge; Based on the object grid, the important objects and their behaviors in the network science and technology information are identified, the important information clues contained in the network resources are revealed, and the information value of the network resources is judged by calculating the matching degree of the two. The scientific and technological information published on the Web site of the US Department of Energy is selected as experimental data to verify the important role of knowledge objects and their relationships in the judgment of intelligence value.
