The fubing system that was a driving force in the creation of Sui and Tang dynasties is generally thought to have begun with the twenty-four army system of the Western Wei, and its military power too have been composed of local militias of Han people in Western Wei and Northern Zhou during which the influx of warriors of the northern Xianbei peoples were not numerous. Nonetheless, the term fubing zhi, the fubing system, is not found in contemporary sources, and was invented in a later period. Tracing the fubing system back to the Western Wei is also nothing more than a distortion created by later hands. The local military organizations that comprised the military force of the twenty-four army system were both chronologically, geographically, and ethnically extremely diverse, and the local Han militias of Guanlong 關隴 were no more than one part of it. In the Western Wei and Northern Zhou levies of military service were generally imposed on households, but they resorted to having the local gentry organize military bands and thereby continued the selection and implementation of a method of operating as a pseudo-tribal militia. In addition the existence of a unique system of groups of close advisers, called qinxhin 親信 and kuzhen 庫眞, whose lineages could be traced to the inner officers of Northern Wei court, made it possible to control the vast military organization that was the twenty-four army system. Judging from these special characteristics, the twenty-four-army system can be understood as a pseudo-tribal militia system that was supported by the traditions of the Xianbei. In this regard, it should be positioned in the historical context as a military system located precisely within the lineage of the nomadic military systems such as the twenty-four chiefs of the Xiongnu and of the Mongol thousand-household system. The imperial edict of the tenth year of Kaihuang, which was promulgated the year after Sui destroyed the Chen, has been taken as revolutionary in creating the ground-breaking fubing system, but in actuality, the purpose of the edict was the transfer and settling of military groups who had served for years in Guanzhong, and their essential character as pseudo-Xiangbei tribal militia was maintained thereafter. A common element underlay both the purpose of the imperial edict of the tenth year of the Kaihuang reign and the Northern-Wei policy of dismantling the tribe-centered state, and in order to decipher this reality, one must seek a point of view from which both can be mutually examined and compared.

従来のWeb検索における適合フィードバックでは,ユーザがサンプルページの内容を見て評価し,その評価をもとに再検索または検索結果の再構成を行なう.その際,ページの評価は「良い」または「悪い」の2種類であった.そのため,従来の適合フィードバックの手法は,「良い」と評価されたページに類似したページを獲得するのには有効だが,ユーザの要求が「この話題についてのより詳しいページが欲しい」などのように複雑になると,十分にユーザの意図を汲み取ることが難しく,うまく機能しないことがあった.そこで,本研究では,単に「良い」または「悪い」の二元論的な評価に基づいて,サンプルページに類似するページを集めるのではなくて,サンプルページと実際に欲しいページの違いを評価として与えることによって,そのような差異を持つページを探してくれるような,意味的な適合フィードバック機構を提案する.ページ間の差異としては,各ページ中の単語数や,お互いのページ内の単語の共起度を用いて,ページ間の情報量や話題の広がりの相対的な差を測定する.In conventional relevance feedback for Web query systems, the user evaluates some sample pages, and then based on that evaluation, the original query is revised, or the query results are reorganized. In that evaluation, sample pages are classified as good or bad. This approach is effective to find pages similar to the pages evaluated as good. In some cases, however, the users want to specify their requirements more specifically, such as, "I want pages discussing this topic in more detail." In the usual relevance feedback, the users cannot express such requirements in the evaluation. In this paper, we propose a framework where the users can express such requirements, which we call semantic relevance feedback. In our framework, the users specify the difference between a sample page and pages they want. We estimate the difference between pages based on the amount of information and the extent of the topic in each page. We measure the former by the number of word occurrences, and measure the latter by the ratio of cooccurrence of words in pages.
