【摘要】：為幫助科研人員從海量的網(wǎng)絡(luò)科技信息中發(fā)現(xiàn)高情報(bào)價(jià)值的信息資源,提高其網(wǎng)絡(luò)信息的利用效率,本文通過對(duì)知識(shí)對(duì)象屬性及對(duì)象間相互關(guān)系進(jìn)行計(jì)算,提出網(wǎng)絡(luò)科技信息情報(bào)價(jià)值判斷的新思路,具體包括三個(gè)部分:基于對(duì)象及其行為構(gòu)建情報(bào)關(guān)注模型,對(duì)科研人員的先驗(yàn)證知識(shí)進(jìn)行結(jié)構(gòu)化描述;基于對(duì)象網(wǎng)格實(shí)現(xiàn)網(wǎng)絡(luò)科技信息中重要對(duì)象及其行為的識(shí)別,對(duì)網(wǎng)絡(luò)資源中蘊(yùn)含的重要情報(bào)線索進(jìn)行揭示;通過計(jì)算二者的匹配度對(duì)網(wǎng)絡(luò)資源的情報(bào)價(jià)值進(jìn)行判斷。選取美國能源部網(wǎng)站發(fā)布的科技信息作為實(shí)驗(yàn)數(shù)據(jù),驗(yàn)證了知識(shí)對(duì)象及對(duì)象間關(guān)系在情報(bào)價(jià)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.
