  Returning to FIG. 1 again, a functional block diagram in the information processing apparatus 100 will be described. The document data receiving unit 130 receives document data from the access destination document data providing apparatus. The document data receiving unit 130 presents the document data to the user on the display unit 111, while delivering the same document data to the genre analysis unit 140.

  The genre analysis unit 140 analyzes what genre the document data belongs to by analyzing words in the document data. The concept of the genre analyzed by the genre analysis unit 140 is shown in FIG. FIG. 3 is a diagram schematically showing the concept of a genre handled by the information processing apparatus according to the embodiment of the present invention.

  As shown in FIG. 3, the genre handled by the information processing apparatus 100 is gradually branched from a large item, and proceeds to a more detailed genre. The genre analysis unit 140 analyzes the contents of the document data, but if the detailed genre cannot be specified, the genre analysis unit 140 analyzes the genre of the item close to the large item (for example, “ball game”) and the more detailed genre. In such a case, a genre of a more detailed item (for example, “ball game” → “baseball” → “major league”) separated from the large item is specified.

The genre analysis unit 140 of the information processing apparatus 100 has a genre analysis dictionary database 135 used for genre analysis of document data. When analyzing a predetermined document, the genre analysis unit 140 picks up a word from the document data, and determines the genre to which the document data belongs based on the relationship with the picked-up word. A genre analysis dictionary database 135 is a database of relations between words and genres. Note that various well-known algorithms can be used for the genre analysis algorithm of the genre analysis unit 140.
The “genre analysis unit” in the claims is a conceptual representation of the genre analysis unit 140.

  The browsing time calculation unit 141 calculates the time for browsing a predetermined document data providing apparatus. The time measuring unit 142 of the information processing apparatus 100 measures the current time, and provides time information when the information processing apparatus 100 accesses a predetermined document data providing apparatus. The “browsing time calculation means” in the claims is a high-level conceptual view of the browsing time calculation section 141, and the “time counting means” in the claims is a high-level conceptual view. It is shown in.

  When the information processing apparatus 100 accesses a predetermined document data providing apparatus, the “genre” analyzed by the genre analyzing unit 140 and the “browsing time” calculated by the browsing time calculating unit 141 and the time measuring unit 142 are counted. The “access time” is stored in the search-oriented database 150 as a group of “search-oriented data”.

  The accumulation of data in the search-oriented database 150 will be described more specifically with reference to FIG. FIG. 4 is a diagram schematically showing a search-oriented data collection process in the information processing apparatus according to the embodiment of the present invention. Consider a case where the user of the information processing apparatus 100 accesses the document data providing apparatus 200c, for example. At this time, it is assumed that the genre analysis unit 140 analyzes that the genre to which the document data provided by the document data providing apparatus 200c belongs is “digital camera”. Further, it is assumed that the browsing time calculation unit 141 calculates that the time for browsing the document data provided by the document data providing apparatus 200c is “10 minutes 30 seconds”. In addition, it is assumed that the access time counted by the timing unit 142 is “2008/6/19 15:00:00”. In such a case, data as shown in (1) of FIG.

  Next, for example, consider a case where the document data providing apparatus 200d is accessed. At this time, it is assumed that the genre analysis unit 140 analyzes that the genre to which the document data provided by the document data providing apparatus 200d belongs is “Japanese sake”. Further, it is assumed that the browsing time calculation unit 141 calculates that the time for browsing the document data provided by the document data providing apparatus 200c is “20 seconds”. In addition, it is assumed that the access time counted by the timing unit 142 is “2008/6/19 15:11:00”. In such a case, data is basically stored in the search-oriented database 150 as shown in (2) of FIG. 4, but the browsing time calculated by the browsing time calculation unit 141 is merely used. Since the data shown in (2) of FIG. 4 is relatively short, such as 20 seconds, there is a possibility of causing noise when using the search-oriented database 150. Therefore, the data (2) may be discarded. . “Accumulating only the genre of the document data whose browsing time calculated by the browsing time calculation means is equal to or longer than a predetermined browsing time in the search-oriented database as search-oriented data” in the claims is such data destruction Is a high-level concept. The browsing time calculation unit 141 calculates the time for browsing a predetermined document data providing apparatus, but is not limited to this embodiment. For example, when the operator selects a link transmitted from the search device 300, the search device 300 is informed of the start of browsing time measurement, and the end of measurement is searched when the operator accesses another link destination from the link. By notifying the device 300, the search device 300 can calculate the browsing time from the measurement start of the browsing time to the end of the measurement. That is, the browsing time may be measured by either the client or the server, or by a browser for accessing information.

  Next, consider a case where the user of the information processing apparatus 100 accesses the document data providing apparatus 200f, for example. At this time, it is assumed that the genre analysis unit 140 analyzes that the genre to which the document data provided by the document data providing apparatus 200f belongs is “pet”. Further, it is assumed that the browsing time calculation unit 141 calculates that the time when the document data provided by the document data providing apparatus 200c is browsed is “7:00”. In addition, it is assumed that the access time counted by the timing unit 142 is “2008/6/19 15:13:00”. In such a case, data accumulation as shown in (3) of FIG.

  Next, an example of how to use the data accumulated in the search-oriented database 150 as described above will be described.

  The search instruction unit 160 is configured to make a search instruction request to the search device 300 using a predetermined keyword as a search word. Here, the information processing apparatus 100 according to the present invention is characterized by a keyword regarding the “genre” of the search-oriented data selected from the search-oriented database 150 in addition to the keyword input from the input unit 120 by the user. And a search instruction request to the search device 300. By taking such a “genre” keyword into consideration and instructing the search device 300 to perform a search, according to the information processing device 100 of the present invention, a more accurate search can be performed without requiring the user's burden. It becomes possible to do. The “search instruction means” in the claims is a high-level conception of the search instruction unit 160.

  The “genre” keyword selected from the search-oriented database 150 is arbitrary, but as an example, the “genre” of the latest search-oriented data can be used as the latest keyword. By using the “genre” keyword of the latest search-oriented data in combination with the keyword input by the user, a search instruction including the latest interest of the user is transmitted to the search device 300. According to the information processing apparatus 100 of the present invention, it is possible to execute a highly accurate search according to the latest trend of interest of the user without requiring the user's burden.

  The “latest keyword” in the claims is a high-level conception of the “genre” keyword of the latest search-oriented data.

  A document data providing device designation destination (such as a URL) input from the keyboard 109 or mouse 110 constituting the input unit 120 is sent to the document data acquisition request unit 161. The document data acquisition request unit 161 is displayed by the user. Requests transmission of document data to the designated document data providing apparatus.

  Next, another embodiment of the present invention will be described. FIG. 5 is a diagram for explaining the concept of an information processing apparatus according to another embodiment of the present invention. In FIG. 5, configurations denoted by the same reference numerals as those in FIG. 1 are the same and perform the same functions.

  The present embodiment is different from the previous embodiment in that in addition to the configuration of the previous embodiment, two sort units—a first sort unit 171 and a second sort unit 172—are provided.

  The first sorting unit 171 sorts the search-oriented data stored in the search-oriented database 150 according to the total number of browsing hours by genre. The sorting process of the first sorting unit 171 will be described in more detail. FIG. 6 is a diagram for explaining processing by the first sorting unit 171 of the information processing apparatus 100 according to another embodiment of the present invention.

  As already described, the search-oriented data is combined with “genre”, “browsing time”, and “access time” as one data. Among these, the total browsing time is the sum of all “viewing times” of search-oriented data of the same “genre”. According to the sorting process by the first sorting unit 171, for example, a sorting result as shown in FIG. 6 is obtained. That is, by sorting the search-oriented database 150 by the first sorting unit 171, for example, the genre keyword “digital camera” is ranked first with a total browsing time of 75 hours 25:00, and the genre keyword “Italian cuisine” It is possible to obtain a result such as... In the second place with a total viewing time of 68 hours 38:00.

  It can be predicted that the longer the total browsing time (that is, the higher the ranking by the first sorting unit 171), the higher the user's interest. In the present embodiment, as the “genre” keyword picked up from the search-oriented database 150 and used in the search instruction unit 160, the genre having the highest ranking sorted by the first sorting unit 171 is used as the keyword. That is, in the present embodiment, a keyword that is likely to be of high interest to the user because of the long total browsing time—also referred to as the most frequently used keyword—is used together with the keyword input by the user. According to this, a search instruction in which a matter that the user is most interested in is transmitted to the search device 300. Therefore, according to the information processing device 100 of the present embodiment, without burdening the user, It is possible to execute a highly accurate search that matches the general interest of the user. The “most frequently used keyword” in the claims is a high-level concept of a genre keyword with the longest total browsing time sorted by the first sorting unit 171. Further, the “first sorting means” in the claims is a conceptual representation of the first sorting unit 171.

  Next, the second sort unit 172 will be described. The search result receiving unit 180 is configured to receive a search result by the search device 300, that is, a document data candidate (a candidate for the document data providing device). The search result receiving unit 180 receives the document data received by the search result receiving unit 180. The configuration for sorting the candidates is the second sorting unit 172.

  More specifically, the second sorting unit 172 sorts candidate document data according to the number of appearances of the most frequently occurring keyword in the document data. By such sorting, the search result receiving unit 180 rearranges the document data candidates in the order of the user's most important items. Then, by displaying the result rearranged by the second sort unit 172 on the display unit 111, a search result in accordance with the user's interest can be presented.

  The “second sort means” in the claims is a conceptual representation of the second sort unit 172.

  Note that the function of the second sorting unit 172 may be provided on the search device 300 side. That is, when the search device 300 extracts browseable document data candidates based on a plurality of keywords from the information processing device 100, the search device 300 depends on the number of appearances of one of the keywords in the extracted document data. Thus, after sorting, the information processing apparatus 100 answers the candidates for document data that can be browsed. In this case, the search-oriented database 150 is obtained from the information processing apparatus 100 by some method, or the equivalent is stored in the search apparatus 300.

  According to such a search device 300, a search result in accordance with the user's interest can be presented.

  As described above, in the present specification, various embodiments have been described. However, it should be noted that an invention configured by arbitrarily combining the configurations of the respective embodiments can also be included in the scope of the present invention.
