The indexing system used currently in search engine under network environment, specially, WWW environment, has some problems in indexing the increasing various information of the local sites to the robot site. These problems are the followings. The first is to increase network traffics because all documents of the local sites are transferred to the robot site. Because the robot receives unnecessary information which contains useless stop words, special letters, total of the repeated keywords in each document at local sites. The second is the difficulty to maintain the recent information because the time interval for the robot to revisit to each local site is longer as the number of local sites is increased gradually. The third is that it takes long time for the robot agent to parse all documents transferred to its site. To resolve these problems, this paper suggests a VITAR mechanism and we proves its efficiency through performance evaluation by comparing with the current central index mechanism. In our mechanism a document is created, updated, and deleted in its local site. Then, the local index agent parses the document, constructs keyword message(we call it as K-message), and sends it to the virtual index site. The advantages of VITAR are the followings. The first is to be able to reduce network traffics because it transfers only keyword messages to robot site. The second is to be able to remove the parsing time in robot site because of the beforehand parsing at the local site. Finally the third advantage is to be able to maintain the most recent meta information because the virtual index database is updated as soon as changes of documents occur in each local site. Especially, in the case of creation type of a document, we are able to get the effect to save average 80.3% in the network traffic amount comparing with the central index mechanism. 최근에 사용중인 검색엔진은 증가하는 지역사이트의 정보를 로봇사이트에 인덱스 하는데 많은 문제점이 있다. 첫째 지역사이트의 문서 전체를 로봇사이트로 전송하므로 네트워크의 트래픽을 증가시킨다. 왜냐하면 인덱스 하는데 불필요한 불용어와 특수문자, 중복된 키워드 전체를 전송하기 때문이다. 둘째 지역사이트의 증가로 인해 로봇의 방문주기가 길어지므로 최근의 정보를 유지하는데 어려움이 있다. 마지막으로 문서를 로봇사이트에서 파싱하므로 파싱 시간이 길다. 이러한 문제점을 해결하기 위해 본 논문에서는 VITAR방식을 제안하고, 중앙집중식 인덱스방식과 성능을 비교 분석한다. 이 방식은 지역사이트에서 문서를 생성, 갱신, 삭제하고 지역 인덱스에이전트에 의해 파싱한 후 푸싱기법을 이용하여 가상인덱스에 키워드 메시지만을 전송한다. VITAR방식의 장점은 키워드 메시지만을 전송하므로 네트워크 트래픽을 줄일 수 있고, 지역사이트에서 미리 파싱하므로 파싱 시간을 줄일 수 있으며, 각 지역사이트의 문서가 변경되는 즉시 가상인덱스가 변경되므로 인해 최근의 자료를 유지할 수 있다. 특히 중앙집중식 인덱스방식과 성능을 비교 분석한 결과 생성타입인 경우 80.3%의 전송 절감효과를 얻을 수 있었다.

It has been studied the system and the classification for the narrative which selects and puts in on record in the Orient, in this manuscript before it is investigated the classification, the evolution and the purport of the political narrative from Confucian point of view. It was the thought of the oriental Confucian literature of the Orient that literature must take on the way. It is called Jae-do-jee-gi(載道之器). Until the Western theory of literature was introduced in the Orient, this was the firm theory which had never taken a challenge before. So that these included the subject of the narrative recording. It just excluded narrative which was not worth a plugged nicked or did not exist bosasung(補史性). Even if the narrative was given in a dictionary, the fact would have reported the matter to an emperor, moreover it would have broadly given currency to the people. Repeatedly the narrative which was not worth a plugged nicked when they had reported the matter to kings of many previous generations or the people were not enlightened would be excepted the subject of recording. By the way, in the Orient, there was specially a narrative recording management with the Confucian political object of publishing the union of church and state from the quite early season. According to historical record it was Ju-in(?人), a passersby, a Chai-si diadem, a Pagoan, a narration extra, an opinion book, a narration of an opinion book, a man of an opinion book, a narration, a novelist and so on. This manuscript set up some system of the evolution theory though the record related to them in the variety of literature. Namely it was switched a Chai-si diadem to a Pagoan, a Pagoan to a narration, a narration to a novelist. On the other hand, on the authority of the canon of classification of the Book of Song's poetry, this manuscript tried out classification of a political narrative in conclusion. The classification was as follows. 1) The genre story of the rise and decline (1) The genre story of prosperity(the story of justice style) ① Good government story ② Morality story (2) The genre story of decline (the story of anti-justice style) ① The misgovernment story ② Unmorality story 2) The genre story of good advice From now on the present writer will continually write an regular thesis on the political story of Korean based on the thesis above.
