    • A registration method for structured documents includes the steps of: preparing correspondence data between a string and a string occurrence position within a structured document for each structured document, and additionally storing the correspondence data in an occurrence frequency extracting index; and preparing a list of a character, an element containing the character and a length of the element and additionally storing the list in an element length index. A search method for structured documents includes the steps of: inputting search conditions including a search term and an element for specifying a search range; decomposing the search term into a plurality of substrings, obtaining an occurrence frequency and an occurrence position of the search term using the plurality of substrings from the occurrence frequency extracting index; selecting a character from the search term, obtaining an element containing the character using the character from the element length index, and further extracting a length of the element within the search range; calculating a matching degree for the search conditions from the occurrence frequency and the occurrence position of the search term and the length of the element within the search range; and outputting the element containing the search term and the matching degree.
    • 结构化文档的注册方法包括以下步骤:为每个结构化文档准备在结构化文档内的字符串和字符串发生位置之间的对应数据,并且将对应数据另外存储在发生频率提取索引中; 以及准备字符的列表,包含该元素的字符和长度的元素,并另外将该列表存储在元素长度索引中。 用于结构化文档的搜索方法包括以下步骤:输入包括搜索项和用于指定搜索范围的元素的搜索条件; 将搜索项分解为多个子串,使用来自发生频率提取索引的多个子串来获得搜索项的出现频率和出现位置; 从所述搜索项中选择一个字符,从所述元素长度索引获得包含所述字符的元素,并进一步提取所述元素在所述搜索范围内的长度; 根据搜索项的出现频率和出现位置以及搜索范围内的元素的长度来计算搜索条件的匹配度; 并输出包含搜索项和匹配度的元素。

    • The present technology relates to a receiving device, a receiving method, a program, and a receiving system which may improve reception performance in the case of receiving a signal with a variable frequency band. A receiving device according to an embodiment of the present technology includes a demodulation unit configured to convert a received signal to a baseband signal in the case where a first frequency differs from a second frequency, wherein the first frequency is a center frequency in a band of the received signal, the second frequency is a center frequency in a band of a desired signal included in a part of the band of the received signal, and a DC component of the baseband signal is to be a frequency in the vicinity of the second frequency. The present technology may be applied to a receiver which receives an OFDM signal of DVB-C2.
