20080215526 | Information processing apparatus, informaition processing method, and information processing program - In an information processing apparatus, an acquisition unit acquires a keyword, and a calculation unit calculates the importance level of each keyword by adding a value determined depending on an increase in the number of occurrences to the importance level and subtracting a value determined depending on an increase in the difference between a current time and a last acquisition time to the importance level. An extraction unit extracts text information of a subtitle in a program. A subtitle morphological analysis unit morphologically analyzes the text information of the subtitle. A comparison unit compares each acquired keyword with each keyword detected via the morphological analysis. A recording unit records the program if the comparison indicates that any acquired keyword is identical to any keyword detected via the morphological analysis. A registration unit registers the recorded program and information indicating the importance level in a table in association with the keyword. | 09-04-2008 |
20080215577 | Information processing apparatus and method, program, and storage medium - An information processing apparatus includes: an acquiring section acquiring metadata of content; a morphological analysis section performing a morphological analysis of text information included in the metadata of the content; a genre extracting section extracting genre information for each individual content in the metadata of the content; and a keyword extracting section extracting words with attributes that have relevance to the genre of predetermined content in the metadata of the content by a morphological analysis result of the morphological analysis section. | 09-04-2008 |
20080216123 | Information processing apparatus, information processing method and information processing program - In an information processing apparatus, a text information receiving unit receives text information, and a received text morphological analysis unit performs morphological analysis on the text information. An extraction unit extracts text information of a subtitle included in a program. A subtitle text morphological analysis unit performs morphological analysis on the text information of the subtitle. A similarity calculation unit calculates the similarity between a keyword included in a result of the received text morphological analysis performed by the received text morphological analysis unit and a keyword included in a result of the subtitle text morphological analysis performed by the subtitle text morphological analysis unit. A comparison unit compares the similarity with a predetermined threshold value. A recording unit records the program at a time at which the comparison unit determines that the subtitle text of the program currently includes a keyword having similarity higher than the predetermined threshold value. | 09-04-2008 |
20090077067 | Information processing apparatus, method, and program - An information processing apparatus which may include acquisition means for acquiring meta-data of a content; morphological analyzing means for performing morphological analysis on text information included in the meta-data of the content; comparison means for comparing a morphological analysis result of the morphological analyzing means and a plurality of list patterns of predetermined performer names; and when there is a list pattern of predetermined performer names having matched at least one part or more out of the morphological analysis result on the basis of the comparison result of the comparison means, first extraction means for extracting a performer name with the list pattern of the matched predetermined performer name. | 03-19-2009 |
20100030771 | Information processing apparatus and method, and recording medium - An information processing apparatus includes an obtaining unit configured to obtain program information on programs to be broadcast in a predetermined time period; a keyword extraction unit configured to extract keywords obtained by performing morphological analysis on text data contained in the obtained program information in such a manner as to be associated with corresponding programs; a current-affairs keyword extraction unit configured to extract, as current-affairs keywords, keywords that are associated with corresponding programs to be broadcast on a plurality of different broadcast stations and that are associated with only programs to be broadcast today from among the keywords extracted by the keyword extraction unit, wherein, for each of the extracted current-affairs keywords, the number of appearances of the current-affairs keyword is summed, and an importance degree indicating an importance characteristic of the current-affairs keyword for a user is determined on the basis of the summed number of appearances. | 02-04-2010 |
20100031294 | Information processing apparatus and method, and recording medium - An information processing apparatus includes an obtaining unit configured to obtain program information on programs that are to be broadcast in a predetermined time period; an extraction unit configured to extract keywords indicating the content of the programs from text data contained in the program information; a storage unit configured to prestore theme definition information containing information on the keywords; a theme identifying unit configured to identify which theme a predetermined program belongs to on the basis of the keyword and the theme definition information; and a rate-of-change computation unit configured to compute, for each of the identified themes, a rate of change of the number of times a program belonging to the identified theme is broadcast on a first day in the predetermined time period to the number of times the program is broadcast on a second day. | 02-04-2010 |
20110295971 | INFORMATION PROCESSING SYSTEM, INFORMATION PROCESSING APPARATUS, AND INFORMATION PROCESSING METHOD - Provided is an information processing system including a first information processing apparatus and a second information processing apparatus. The first information processing apparatus includes a content recording unit to record a content and to obtain and record a sights keyword related to the recorded content. The second information processing apparatus includes a place-name accumulating unit to obtain and accumulate place-name information corresponding to a current location of the second information processing apparatus, a sights keyword acquisition unit to obtain the sights keyword recorded on the first information processing apparatus, a sights keyword determining unit to narrow down a sights candidate in the place-name information, to thereby extract sights-candidate place-name information, and to determine the sights keyword corresponding to the sights-candidate place-name information, and a content-record informing unit to inform that a content related to the determined sights keyword is recorded on the first information processing apparatus. | 12-01-2011 |
