    • A data sorting program that is capable of performing a data sorting process by using a small capacity of memory at a fast speed. A computer executing the data sorting program has the following functions. A concise ordered TRIE creator creates a root, sequentially reads the characters of each data, and when a prescribed number of data passed a certain node connected to the root before and a child node corresponding to a character next to a character associated with the certain node has not been created, creates the child node so that the child nodes of the certain node have a prescribed arrangement. A partition determination unit sets partitions between prescribed nodes. A data grouping unit groups the data into a plurality of data groups according to the partitions.
    • 一种数据排序程序,其能够通过以快速的速度使用小容量的存储器来执行数据排序处理。 执行数据排序程序的计算机具有以下功能。 一个简洁的订单TRIE创建者创建一个根,顺序读取每个数据的字符,并且当规定数量的数据通过连接到根的某个节点和与某个节点相关联的字符旁边的对应的子节点 尚未创建,创建子节点,使得某个节点的子节点具有规定的排列。 分区确定单元在规定的节点之间设置分区。 数据分组单元根据分区将数据分组成多个数据组。

    • Provided is a classification device capable of classifying time series data of location information into groups in which continuity of time is secured. The classification device (100) includes a data storage unit (110) that stores time-of-day information and location information corresponding to the time-of-day information, a sorting unit (120) that sorts the location information in order of time using the time-of-day information, a hidden Markov model storage unit (130) storing therein a left-to-right hidden Markov model containing a plurality of states and in which a parameter is undetermined, a Markov model output unit (140) that determines the parameter by inputting the location information sorted in order of time into the hidden Markov model, and a classification unit (150) that classifies each location information in one of the plurality of states by inputting the location information sorted in order of time into the hidden Markov model containing the determined parameter.
