웹 페이지 컨텐츠 점수를 이용한 개선된 페이지랭크 알고리즘

최근 웹 검색 분야에서 검색의 질을 높이기 위한 기법들이 많이 연구되고 있다. 페이지랭크 알고리즘은 구글 검색엔진의 핵심 알고리즘으로써 웹 문서들을 효과적으로 랭킹하는 것으로 알려져 있다. 그러나 기존의 페이지랭크 알고리즘은 링크의 수만을 이용하여 랭킹을 수행하고 있다. 본 논문에서는 단순히 링크의 수뿐만 아니라 웹 페이지의 컨텐츠에 대한 점수를 랭킹에 반영하는 효율적인 알고리즘을 제시한다. 이를 위하여 웹 페이지의 컨텐츠를 점수화하는 기법을 소개하고 링크의 점수에 영향을 주는 2가지의 개선된 알고리즘을 제시한다. 비교 실험을 통해 제안 알고리즘이 기존의 페이지랭크 알고리즘 보다 웹 페이지의 컨텐츠의 점수를 효율적으로 반영함을 보인다.

This study addresses theissue of safety of the splash guard of a computer numerical control (CNC) machine tool at the design stage. As an impact test for evaluating safety requirements such as strength under the safety regulation is an expensive and iterative task, it is necessary to develop a new method to minimize the task of the impact test for development of the machine tool. In this study, explicit finite element method was adopted forreplacement of the impact test of the splash guard of a machine tool at the design stage. A finite element model was developed for implementing the impact test on an actual vertical CNC lathe and then produced the analysis including plastic strain and deformation to enable the safety of its splash guard to be determined. The analysis results demonstrated that the finite element method can be applied to safety evaluation for design of the splash guard of a CNC machine tool.

This paper attempts to ascertain the ways in which John Webster utilizes language and imagery in The White Devil as a way of producing a stunning portrait of chaotic and disintegrated world. With the fragmented and destructive images, I have argued, the playwright succeeds in presenting and representing the endemic chaos of the society which is closely related to the disintegrated principle of justice in the patriarchal order. The dexterous deployment of language and imagery becomes effective in codifying the moments in which the characters strive for defining, but thereby only destroy, one another with their own values and terms. The images of devil, poison, disease, earthquake, witchcraft, and animal serve for a representation of disorder and perversion in the courtly society, inasmuch as the corrupted image of this world is reinforced by the sexualized images of venereal disease, whores, cuckoldry, and adultery. Vittoria's virtuous appropriation of language betrays the fact that the prosecuting male characters are, indeed, prisoners of their own distorted world. With the deliberate juxtaposition of verbal and visual effects, John Webster is able to stage a chaotic and fragmented world which, in turn, proves a scathing criticism on the social injustice of misogynist society.
