[0010] Hereinafter, an embodiment of the present invention (the present embodiment) will be described with reference to the drawings. The embodiment described below is merely an example, and the embodiment to which the present invention is applied is not limited to the following embodiment.

[0011] The information processing device 10 according to the present embodiment is a device that analyzes content posted on a social networking service (SNS). The information processing device 10 includes a posting history acquisition unit 11, an analysis unit 12, a data generation unit 13, and a storage unit 14.

[0012] The posting history acquisition unit 11 acquires posting history data 101. The posting history data 101 is data indicating the history of posts made to the SNS.

[0013] The analysis unit 12 analyzes elements common to the words and phrases included in the posting history data. Specifically, the analysis unit 12 analyzes, for each word and phrase included in the posting history data, the relationship between the word and the posted content before and after the word and phrase are included.

[0014] Based on the analysis result, the data generating unit 13 generates data (specific word data 102) indicating elements common to the words and phrases and information indicating the reliability of each element.

[0015] The storage unit 14 stores posting history data 101 and specific word data 102.

[0016] FIG. 2 is a diagram illustrating an example of posting history data.

[0017] The posting history data 101 includes items such as time, sender, medium, content, and category.

[0018] The value of the item "Time" is the time when the post was made to the SNS. The value of the item "Sender" is an identifier for identifying the sender, such as an account name. The value of the item "Medium" is an identifier for identifying the medium that accepts the post.

[0019] The value of the item "Content" is the posted text. The value of the item "Category" is text that indicates the category selected when posting.

[0020] FIG. 3 is a diagram showing an example of the specific word data 102. As shown in FIG.

[0021] The specific word data 102 includes items such as time period and frequency ranking.

[0022] The value of the item "period" indicates the period for which the frequency of posting of a phrase is to be tallied, in units of hours, days, weeks, months, years, or the like.

[0023] The value of the item "frequency ranking" indicates the phrase that was posted most frequently during the target period, ranked 1st, 2nd, 3rd, etc.

[0024] The phrases to be counted may be words, phrases, or sentences. Furthermore, the analysis unit 12 may regard phrases that include elements in common, even if they are not identical, as being the same. For example, when counting by word, the analysis unit 12 may count "A Company" and "A Company" as the same phrase. Furthermore, when counting by phrase, the analysis unit 12 may count "A do your best" and "A win" as the same phrase, and "A do your best" and "A lose" as different phrases.

[0025] The above-mentioned order of frequency is an example of information indicating the reliability of information. Other information indicating reliability may be used, for example, the reliability of age may be one of "high", "medium" and "low". In this case, when information that can be similarly interpreted is posted multiple times in different ways, the analysis unit 12 may analyze the information so that the reliability increases if the posted information matches, and decreases if the information does not match.

[0026] For example, the analysis unit 12 may determine the reliability of the age to be "low" based only on the posted content "Classmate of celebrity A," but if it is possible to analyze that "celebrity A" and "celebrity B" are classmates, the analysis unit 12 may also analyze the posted content "Classmate of celebrity B" to determine the reliability of the age to be "medium," which is a higher reliability.

[0027] FIG. 4 is a flowchart showing an example of the flow of the specific word data generation process.

[0028] When receiving a user operation or the like, the posting history acquisition unit 11 of the information processing device 10 acquires posting history data (step S101). For example, the posting history acquisition unit 11 may access a server providing an SNS service, periodically tally up the posted history, and store the tally in the storage unit 14 as posting history data 101.

[0029] Next, the analysis unit 12 analyzes the acquired posting history data (step S102). Specifically, the analysis unit 12 breaks down the posted text into words, phrases, or sentences by natural language processing. The analysis unit 12 may determine the identity of words or sentences by using word vectors, etc.

[0030] The data generating unit 13 generates the specific word data 102 based on the analysis result (step S103).

[0031] (Example of Hardware Configuration According to the Present Embodiment) The information processing device 10 can be realized, for example, by making a computer execute a program in which the processing contents described in this embodiment are described. Note that this "computer" may be a physical machine or a virtual machine on the cloud. When a virtual machine is used, the "hardware" described here is virtual hardware.

[0032] The above program can be recorded on a computer-readable recording medium (such as a portable memory) and can be stored or distributed. The above program can also be provided via a network such as the Internet or e-mail.

[0033] Fig. 5 is a diagram showing an example of the hardware configuration of the computer. The computer in Fig. 5 has a drive device 1000, an auxiliary storage device 1002, a memory device 1003, a CPU 1004, an interface device 1005, a display device 1006, an input device 1007, an output device 1008, etc., which are all connected to each other via a bus B.

[0034] The program for realizing the processing on the computer is provided by a recording medium 1001 such as a CD-ROM or a memory card. When the recording medium 1001 storing the program is set in the drive device 1000, the program is installed from the recording medium 1001 to the auxiliary storage device 1002 via the drive device 1000. However, the program does not necessarily have to be installed from the recording medium 1001, but may be downloaded from another computer via a network. The auxiliary storage device 1002 stores the installed program as well as necessary files, data, etc.

[0035] The memory device 1003 reads out and stores the program from the auxiliary storage device 1002 when an instruction to start the program is received. The CPU 1004 realizes the functions related to the device in accordance with the program stored in the memory device 1003. The interface device 1005 is used as an interface for connecting to a network. The display device 1006 displays a GUI (Graphical User Interface) or the like according to a program. The input device 1007 is composed of a keyboard and mouse, buttons, a touch panel, or the like, and is used to input various operation instructions. The output device 1008 outputs the results of calculations.

[0036] According to the information processing device 10 of the present embodiment, data showing elements common to phrases and information showing the reliability of each element is generated. This allows analysis that takes into account the reliability of information. In addition, since the presence or absence of direct communication between senders is not analyzed, for example, common tendencies can be analyzed for SNS users who do not have direct communication through matching.
