摘要： Stream data is provided for realizing precise calculation processing to keep a constant memory usage of a query including a time-based window, and to take all of input data into consideration. A stream data processing server sections the time-based window into sub-windows each with a smaller width by a query time resolution change unit, and a query processing engine executes the aggregation processing based on the sub-window when receiving the stream data to generate an aggregation tuple, and calculates the calculation result of the query including the time-based window by aggregation processing on the aggregation tuple.

摘要： Voice of plural participants during a meeting is obtained and dialogue situations of the participants that change every second are displayed in real time, so that it is possible to provide a meeting visualization system for triggering more positive discussions. Voice data collected from plural voice collecting units associated with plural participants is processed by a voice processing server to extract speech information. The speech information is sequentially input to an aggregation server. A query process is performed for the speech information by a stream data processing unit of the aggregation server, so that activity data such as the accumulation value of speeches of the participants in the meeting is generated. A display processing unit visualizes and displays dialogue situations of the participants by using the sizes of circles and the thicknesses of lines on the basis of the activity data.

摘要： By introducing the concept of negation into an association rule, the number of combinations of items, serving as candidates of the association rule containing negative items, becomes enormous for mining. The invention sorts out frequent itemsets to be included in an association rule in advance by ensuing its upper bound of confidence satisfying conditions of a confidence and a confidence increment input by an user. Also, by checking a logic product for each bit of a bit string reflecting the presence of each item in the itemset, the combinations of items as candidates are pruned. The pruning of unnecessary combinations is effectively carried out. The number of combinations of the items for compiling association rules is reduced.

摘要： A query processing system in which a virtual table to enable multiple mapping to a plurality of databases is provided in a data processing system to receive a query from an application program and partial replicas as copies of part of the data in the virtual table is prepared in storage so that the whole or part of a query can be processed using the partial replicas. For query units which cannot be processed using the partial replica, means to select an appropriate distributed join method and optimization to push down query processing to real databases as far as possible are used. The system allows transparent access to multiple different real databases according to access conditions without changing the column to be accessed in the virtual table or switching the virtual table, thereby eliminating the need to create a new application for each newly developed service.
