摘要:
An apparatus extracts an area having a highest score or a lowest score that is calculated based on evaluation values of points from a target area including a set of a plurality of points that can be distributed at two-dimensional coordinates. It determines whether the area extracted and an area overlapping a plurality of the target areas intersect with each other, and deletes an area having a lower score or a higher score out of the areas determined to intersect with each other. It selects an area having a highest score or a lowest score out of the areas extracted at the extracting and not deleted at the determining. One or a plurality of areas are generated as the target areas based on an area acquired by excluding the area selected from the target area and an area acquired by excluding the area deleted at the determining.

A trajectory interpolation apparatus is disclosed. The first storage part stores first time and first location information of a movable body at the first time. The second storage stores second time and second location information of the movable body at the second time. The calculation part calculates a first moving distance from the first time and a second moving distance from the second time based on a relationship between the time and the speed stored in the second storage part, regarding third time between the first time and the second time. The determination part determines, as the interpolation point, one of intersection points for a circle in which the first location is set as its center and the first moving distance is set as its radius, and another circle in which the second location is set as its center and the second moving distance is set as its radius.

In an information processing apparatus, a first deletion unit deletes, from sets stored in a storage unit, sets having less than a threshold number of included elements and elements existing in only sets whose number is less than a threshold number of occurrences. A grouping unit generates a group of sets associated with each other in terms of commonality of elements out of the sets remaining in the storage unit. A second deletion unit deletes, with respect to each generated group, sets having less than the threshold number of included elements and elements existing in only sets whose number is less than the threshold number of occurrences, from the sets belonging to the group. An output unit outputs a list of elements included in the sets remaining in each group where there are no sets or elements that need to be deleted.

A data partitioning apparatus receives stream data and stores with previous-and-subsequent information that specifies data previous and subsequent to the data. Then, for groups, each of which contains the data that are stored and that are partitioned into the number of the groups, the data partitioning apparatus stores top information specifying data located at the top in a corresponding group and end information specifying data located at the end in the corresponding group. Then, when new data is stored, the data partitioning apparatus specifies data previous and subsequent to the new data and stores the new data by associating it with the previous-and-subsequent information that specifies the data previous and subsequent to the new data. Then, when data is inserted, the data partitioning apparatus updates information for each group such that the difference between the number of data belonging to each group is equal to or less than one.

The matching apparatus 100 stores, with respect to a branching pattern included in event patterns 140a, a reception time of an event that serves as the branching point in a source node that indicates the transition destination of the event, connects the source node to the branch node by a transition with an interval condition, connects the branch nodes to the link node that indicates the linking point at which these branch nodes are linked together, and thereby generates NFAs 140b. Then, the matching apparatus 100 compares event streams 140c with the NFAs 140b to determine whether the event streams 140c includes the event patterns 140a.
摘要:
An occurrence pattern of an event is detected from an event log based upon information concerning plural kinds of relationships defined among events, such as a simultaneity rule, an order rule, a proximity rule, a cause determination rule, and a result prediction rule and an occurrence pattern of the detected event is output. Accordingly, when an occurrence pattern of an event is detected from event data storing information concerning an occurred event, detailed information about an occurrence pattern of an event can be extracted from an event log.

A system analysis program which can accurately analyze the operational status of a system without modifying functions of the system for providing services. A message analysis unit analyzes the contents of collected messages, and determines the times of occurrence of the messages, the process types requested by the messages, and whether or not each of the messages is a request message or a response message. In response to an instruction for model generation, a model generation unit generates a transaction model satisfying at least one limiting condition related to caller-called relationships between processes, based on a set of messages selected in accordance with a selection criterion based on the certainty of existence of caller-called relationships. Then, in response to an instruction for analysis, an analysis unit analyzes the processing status of a transaction based on a protocol log conforming to the transaction model.

A method of collecting, storing, and retrieving knowledge includes the steps of collecting knowledge information from information-source terminals via a network, the knowledge information including information regarding research and development, problems, and solutions of the problems, storing the collected knowledge information in libraries by classifying the collected knowledge information based on a type and an attribute of the collected knowledge information, organizing the stored knowledge information based on importance and frequency of use thereof, storing the organized knowledge information in the libraries after standardizing the organized knowledge information so as to be usable by others, and retrieving the standardized knowledge information from a library in response to a retrieval request so as to provide the retrieved information for a requesting party which made the retrieval request.

An apparatus includes a unit dividing a region into blocks having a predetermined bit length and generating addition data having the predetermined bit length corresponding to coordinate data, a unit storing storage data having the predetermined bit length, a unit generating composite data having a bit length twice the length of the predetermined bit length by connecting the addition data to the storage data, and storing the composite data, and a unit repeating an operation of designating the bit length of the composite data as the predetermined bit length, instructing to generate the addition data, and instructing to generate and store the composite data. The number of different bits between a bit string of a location corresponding to the input coordinate data and a bit string of a reference location tends to increase as a distance between the location corresponding to the coordinate data and the reference location increases.

A matching device builds a parse tree from an event pattern. The matching device builds an automaton by, while traversing the parse tree, joining child nodes of an AND node in parallel to the AND node and joining child nodes of an OR node in parallel to the OR node. The matching device performs matching of determining whether an event stream includes the event pattern by comparing the event stream with the automaton.
