Abstract: An information processing apparatus determines a threshold value of the number of times of use of a keyword on the basis of the number of times of use of the keyword in each unit period included in a cycle period. Next, the information processing apparatus identifies a period in which the numbers of times of use exceeds the threshold value in the cycle period as a candidate of a popularity period of the keyword. Next, the information processing apparatus excludes the identified period from the popularity period if a situation in which the numbers of times of use in the identified period exceed the threshold value is different from a situation based on a periodic popularity of the keyword. When the identified candidate period is not excluded from the popularity period, the information processing apparatus determines the identified period to be the popularity period.
Abstract translation: 信息处理装置根据包含在循环周期中的每个单位周期中的关键字的使用次数来确定关键字的使用次数的阈值。 接下来，信息处理装置将周期中的使用次数超过阈值的周期作为关键字的受欢迎期间的候补。 接下来，如果识别期间的使用次数超过阈值的情况与基于关键字的周期性普及的情况不同，则信息处理装置将识别的期间从流行期间排除。 当所识别的候选周期未被从流行期间排除时，信息处理装置将识别的周期确定为受欢迎期。

Abstract: A category highly relevant to a keyword combination including a plurality of keywords is extracted. An information processing apparatus extracts a category where the number of times when the category is specified as a search condition along with a first keyword is greater than or equal to a first threshold value from among a plurality of categories that are hierarchized in a tree structure. Subsequently, from among categories corresponding to descendants of the extracted category, the information processing apparatus extracts a category where the number of times when the category is specified as a search condition along with a second keyword is greater than or equal to a second threshold value as a category relevant to a combination of the first keyword and the second keyword.
Abstract translation: 提取与包括多个关键字的关键字组合高度相关的类别。 信息处理设备从树结构中分层的多个类别中提取类别，其中类别被指定为搜索条件的次数与第一关键字一起大于或等于第一阈值。 随后，从对应于所提取的类别的后代的类别中，信息处理设备提取类别，其中类别被指定为搜索条件的次数以及第二关键字大于或等于第二阈值作为 与第一关键字和第二关键词的组合相关的类别。

Abstract: A search query of a search word entered by the user is received, the received search queries are stored in accordance with reception order, a preceding search query whose reception order is earlier than that of the received search query is extracted on the basis of a preset search query extracting condition, a preceding search word constructing the extracted preceding search query and a search word constructing the received search query are stored as a character string set, a character string set having the search word which is the same or similar to the preceding search word is extracted in accordance with a preset character string set extraction start condition (S51), a character set as a related word is specified from the extracted character string set on the basis of a preset registration condition (S53), and the specified character string set is registered as related words into a related-word database (S54).
