Construction of query concepts based on feature clustering of documents

In Information Retrieval, since it is hard to identify users’ information needs, many approaches have been tried to solve this problem by expanding initial queries and reweighting the terms in the expanded queries using users’ relevance judgments. Although relevance feedback is most effective when relevance information about retrieved documents is provided by users, it is not always available. Another solution is to use correlated terms for query expansion. The main problem with this approach is how to construct the term-term correlations that can be used effectively to improve retrieval performance. In this study, we try to construct query concepts that denote users’ information needs from a document space, rather than to reformulate initial queries using the term correlations and/or users’ relevance feedback. To form query concepts, we extract features from each document, and then cluster the features into primitive concepts that are then used to form query concepts. Experiments are performed on the Associated Press (AP) dataset taken from the TREC collection. The experimental evaluation shows that our proposed framework called QCM (Query Concept Method) outperforms baseline probabilistic retrieval model on TREC retrieval.

Manufacture and Date of a Goryeo dynasty Sutra Box with Mother-of-pearl Inlaid Decoration at the Rijksmuseum,Amsterdam

Currently, about ten Goryeo dynasty (918–1392 CE) sutra boxes are preserved in museums in Korea, Japan, the United States, the Netherlands, and the United Kingdom. This article is the result of an examination of a sutra box in the collection of the Rijksmuseum, Amsterdam (hereafter ‘Rijksmuseum sutra box’), which was first introduced to a European audience in the Transactions and Proceedings of the Japanese Society, in 1913–1914. The Rijksmuseum sutra box differs from other Goryeo sutra boxes. With its altered structure and modified motifs, this box bears significant value, not only for the research of thirteenth-century Goryeo mother-of-pearl art, but also for the study of cross-cultural adaptations in East Asian lacquer art. This article investigates the date of manufacture of the sutra box by analysing the manufacturing techniques and its various original and modified parts. For this, an X-ray radiograph was carried out for the first time. As a result, discoveries have been made regarding the structure and decoration of the lower part, which has been modified and is different from Goryeo mother-of-pearl sutra boxes. Finally, this paper reconsiders conservation and repair of Goryeo sutra boxes, as illuminated by an understanding of the original and repaired parts of this box.
