In this paper, we propose a method for constructing a judging model of closeness in human relations, which plays an important role in human communication. The purpose of this model is to clarify the correlation between linguistic honorific expressions and closeness in order to develop a support tool related to the utilization of honorific expressions using information technology. Existing studies...
Many commercial DBMSs based on a column-oriented storage method have been used to analyze large-scale data. However, the column-oriented DBMS is difficult to use for processing big-data analysis updated in real time, because the column-oriented storage performs inefficient OLTP when processing row-oriented updates. Therefore, we attempted to enable the column-oriented DBMS to efficiently process OLTP...
Database systems have recently utilized both row-and a column-oriented storage systems, also termed as hybrid storage, as their storage devices for large scale data management. The hybrid storage based database systems should ideally be operated on distributed computing environments for query optimization, however, studies on query optimization of such database systems are not available in literature...
