This paper proposes a methodology applying sequence tagging methodology to improve the performance of NER(Named Entity Recognition) used in QA system. In order to retrieve the correct answers stored in the database, it is necessary to switch the user's query into a language of the database such as SQL(Structured Query Language). Then, the computer can recognize the language of the user. This is the process of identifying the class or data name contained in the database. The method of retrieving the words contained in the query in the existing database and recognizing the object does not identify the homophone and the word phrases because it does not consider the context of the user's query. If there are multiple search results, all of them are returned as a result, so there can be many interpretations on the query and the time complexity for the calculation becomes large. To overcome these, this study aims to solve this problem by reflecting the contextual meaning of the query using Bidirectional LSTM-CRF. Also we tried to solve the disadvantages of the neural network model which can't identify the untrained words by using ontology knowledge based feature. Experiments were conducted on the ontology knowledge base of music domain and the performance was evaluated. In order to accurately evaluate the performance of the L-Bidirectional LSTM-CRF proposed in this study, we experimented with converting the words included in the learned query into untrained words in order to test whether the words were included in the database but correctly identified the untrained words. As a result, it was possible to recognize objects considering the context and can recognize the untrained words without re-training the L-Bidirectional LSTM-CRF mode, and it is confirmed that the performance of the object recognition as a whole is improved.

A ritual ceremony accompanied by a song and dance is called as Kagura in Japan. The word Kagura is originally derived from Kamukura, which means the place where spirits reside. However, later it came to refer to the whole process of the ritual ceremony itself. Through the field studies, this paper examines Takachiho-kagura, helded in Takachiho, known as the village of myths, located in northern Miyazaki-ken in Japan. Kagura takes place all night through in each and every village in Takachiho and it normally runs from the end of November when the harvest season ends until early February the next year. One ordinary house is especially chosen for this ceremony, in which Kagura performs 33 repertoires. Takachiho-kagura is sometimes called as Yokagura, since the performance takes place over-night. A song and dance is performed by ordinary village people called hoshyadong, who inherited Takachiho-kagura. Currently, the ceremony is held in more than 20 villages and designated by the government as "Important Intangible Folk Cultural Property" in Japan. Takachiho-kagura follows the example of rituals held in Sada shrine in Izumo, which is now eastern Hiroshima-ken. It is the dance using a bell, a sword, a fan, which signify Norimono and is usually combined with mask-play called as Shinno. From the shrine of village, itwelcomes the gods who defense their village, called Ujikami and other 8 million gods, called Yaoyorozunokami, in Kagurayado, where Kagura of 33 repertoires is played in order. Kagura starts from dances for attendance of the gods, Hikomai, Daidono, Kamioroshi, performs dances of Amanoiwato, the gate of heaven's cave in Japanese myths, Dazikara, Uzume, Dotori, and continues dances for the old ghosts Shibahiki, Yatsubachi mixed with acrobatics. Finally, this performance ends with dances to send off the gods, Hinomae, Gurioroshi, Gumooroshi, until the dawn the next morning. This paper explores Takachiho-kagura from the perspective of folk performance with ethnography. These days, ecstasy and oracle do not happen in Takachiho-kagura. However, it kept the old form of folk performance as Kagura held in ordinary house. Especially, in Takachiho, remarkable venue of the Japanese myths, Takachiho-kagura is developed artistically. The first field study was held in Gokamura, Iwato-zone and Ashakabe, Mitai-zone between December 6th and December 12th 1997. Afterwards, the second field study was conducted in the area of Shiba and Ashakabe from December 17th until December 19th 1997 and from December 1st until December 10th 2000.

This work began with the aim of examining the history of the concept "cultural property" that is expected to disappear, and the main subject of research was the history that preceded the spread of this notion throughout society. The phrase "cultural property" first appeared in the 1920s, and was used in various fields such as literature, history, music, and philosophy in the context of cultural resources. Until immediately following liberation from the Japanese colonial era, the meaning of cultural assets was widely applied in the range of "cultural resources," and during this period, it was often used to help supplant the reality and history of Japanese occupation. Immediately after the Korean War, it was also employed for the purpose of 'restoration of cultural resources through war'. Recognition of cultural property directly influenced by Japan's Cultural Heritage Protection Act has occurred since 1950s. In the early 1960s, the enactment of various laws related to cultural properties and the establishment of the Cultural Heritage Administration caused the meaning of cultural property to be limited to 'cultural heritage'. In this way, the definition of state-led cultural property has continued to apply to this day. It has not been clearly confirmed whether the concept of cultural properties was imported from Japan through means such as the Cultural Heritage Protection Act. Cases in which several Japanese students endorsed the concept of cultural property within Korea serve to increase the likelihood that the concept was indeed imported from Japan. However, "coined language using multiple Chinese characters," "the phenomenon of cultural complex words in the 1920s,", and "cases of non-Japanese international students using the concept of cultural property" also open up the possibility of their own occurrence. Apart from the general importance of the concept of cultural property, intellectuals at the time used this concept to promote internal development and the overcoming of colonial Joseon. In this research, it was confirmed that the conceptual word cultural property was older and had a wider history than the general perception had indicated previously. The history of the conceptual term "cultural property" may appear to be more than 60 years old based on the enactment of the Cultural Heritage Protection Act, but in fact it is nearly 100 years old when traced back to on 1925, as established here. In general, the creation and disappearance of terms may proceed naturally with social change, but such terms may alternatively be created or erased through national policy. Identifying the origins of a phrase that is about to disappear represents a significant task for purposes of establishing its historical meaning.
