In the user information table TB1, “user ID” and “password” are described in association with each other. In the “user ID” field, identification information uniquely assigned to the SNS user is described. Information for indicating a valid user corresponding to the identification information is described in the “password” field.

  The post management table TB2 stored in the storage unit 22 will be described. FIG. 5 is a diagram illustrating an example of the posting management table TB2. In the post management table TB2, information posted to the electronic diary and information for managing the information are described. The post management table TB2 includes “user ID (diary contributor)”, “diary post date”, “diary information text”, “user ID (comment poster)”, and “comment post date”. And “comment information text” are described in association with each other. In the “user ID (diary contributor)” field, the user ID of the diary contributor who posted the diary information is described. In other words, the user ID of the diary contributor corresponds to the contributor information that identifies the contributor of the post information. In the “diary posting date and time” field, the date and time when the diary information was posted is described. This date and time is, for example, a value representing a date (year / month / day) and time (hour / minute / second). In the “diary information text” field, the contents of the diary information are described. In the “user ID (comment contributor)” field, the user ID of the comment contributor who posted the comment information or the user ID of the administrator of the SNS who has set an instruction to post automatic comment information. Is described. It is assumed that the user ID of the SNS administrator is “USER99”. In the “comment posting date / time” field, the date / time when either comment information or automatic comment information is posted is described. In the “comment information text” field, the content of either comment information or automatic comment information is described. In other words, the storage unit 22 stores the post information and poster information received by the post information receiving means and the comment information whose post information is the comment destination among the comments received by the comment information receiving means. It corresponds to the information storage means. When diary information is posted, no information is described in the fields of “user ID (comment poster)”, “comment posting date / time”, and “comment information text”. In the following description, the state in which no information is described is referred to as “NULL”.

  The posting program PG1 stored in the storage unit 22 will be described. The posting program PG1 describes a procedure of processing (hereinafter referred to as automatic comment processing) for creating and posting automatic comment information for certain diary information. More specifically, the control unit 21 executes the posting program PG1 to identify the diary information whose similarity is specified to be equal to or higher than a predetermined value with respect to the diary information of the user who receives the automatic comment processing service. A function that identifies a phrase as similar diary information, a function that identifies words frequently included in comment information posted to a plurality of identified similar diary information, and generates comment information that includes the identified phrase And a function for posting the generated comment information as automatic comment information. The posting program PG1 is executed at a predetermined timing determined by the SNS administrator. The predetermined timing in this embodiment is immediately after the diary information of the user who receives the service of the automatic comment processing is posted. In addition, it is assumed that the function realized by executing the posting program PG1 is controlled by information described in the specific condition table TB3.

  The specific condition table TB3 stored in the storage unit 22 will be described. FIG. 6 is a diagram illustrating an example of the specific condition table TB3. In the specific condition table TB3, conditions for specifying similar diary information (hereinafter referred to as specific conditions) are described. As shown in the figure, the specific condition table TB3 includes “specific target”, “specific target period”, and “similarity” corresponding to the specific condition described in the “specific condition” field. It is described in correspondence. The SNS administrator instructs the control unit 21 to change the information described in the specific condition table TB3 and to change the specific condition applied when the posting program PG1 is executed by operating the operation unit 24. Shall be able to. That is, the control unit 21 corresponds to a period changing unit that changes the period described as the specific condition, and a threshold changing unit that changes the similarity threshold.

  In the specific condition table TB3, a specific object corresponding to the specific condition such as “electronic diary” and “SNS” is described in the “specific object” field. This specific target refers to diary information for which it is determined whether or not it is similar diary information. When “electronic diary” is described in the “specific target” field, the control unit 21 applies similar diary to diary information associated with the user ID of the user who receives the automatic comment processing service. It is determined whether or not the information is specified. In addition, when “SNS” is described in the “specific target” field, the control unit 21 performs similar diary information on diary information included in all electronic diaries provided as SNS by the server device 20. Determine whether to specify.

  The reason for making the specific target variable in this way is based on the reason that the expressions included in the diary information and the comment information may differ depending on the relationship between the diary poster who posted the information and the comment poster. For example, as shown in the post management table TB2 of FIG. 5, the diary contributor uses the word “Yabai” as a positive expression and a negative expression in the diary information.

  For example, when “electronic diary” is described in the “specific target” field, the comment information for the diary information specified as similar diary information is the diary information posted by the user who receives the automatic comment processing service. It is often posted by people who are interested in the topic or acquaintances of the person who posted the diary information, and includes words and phrases that are related to the topic of the diary information or words that are used by an acquaintance. The possibility increases.

  Further, for example, when “SNS” is described in the “specific target” field, not only the diary information of the user who receives the service of the automatic comment processing but also the diary information of other users as the similar diary information. Included in the identified information. That is, the diary information specified as the similar diary information includes not only information close to the topic of the diary information of the user who receives the service of the automatic comment processing, but also information on other topics. Accordingly, the similar diary information is less likely to include uncommon words such as words related to the topic of the diary information and words used by acquaintances.

Next, in the specific condition table TB3, the “specific target period” field describes a specific target period corresponding to the specific condition, such as “1 month” or “10 years”. This identification target period is for identifying the diary information close to the latest topic posted by the user who receives the automatic comment processing service when identifying the similar diary information.
The control unit 21 determines whether or not the diary information posted in the specific target period described in the “specific target period” field is specified as similar diary information. For example, when “one month” is described in the “specific target period” field, the control unit 21 specifies the diary information posted from one month before the current date and time as similar diary information. Determine whether or not.

In this way, the specific target period is specified in terms of the words included in the diary information, although the standard word usage rate is high in the long term, but in the latest diary information topic, it is used for the recent topic in the short term. This is based on the reason that the usage rate of words and phrases used in recent wording is high.
Therefore, if a relatively short period such as one month is set in the “specific target period” field, words and phrases used in recent topics are compared with a relatively long period such as 10 years. There is a high possibility that diary information including phrases used in recent wording is specified as similar diary information.
In addition, if a relatively long period such as 10 years is set in the “specific target period” field, information used as a recent topic or used in recent words in information specified as similar diary information The ratio of diary information that includes the phrase to be processed is reduced.

Next, in the specific condition table TB3, a “similarity” field describes a similarity threshold used for determining whether or not the diary information is similar diary information.
First, when comparing two sentences, the degree of similarity is determined by dividing the sentence into morphemes using a well-known morphological analysis technique, and how similar the morphemes contained in one sentence are compared with the other sentence. It is the value which quantified. For this reason, the more the same morpheme is in two sentences, the higher the similarity is. The less the same morpheme is in two sentences, the lower the similarity is.

When “a” is described in the similarity field (a is a predetermined similarity value), the control unit 21 reads the diary information posted by the user of the automatic comment processing service, and “specific target”. The degree of similarity with the diary information specified by the information described in the field “” is obtained, and among the diary information specified by the information described in the “specification target” field, the degree of similarity is “a”. The higher diary information is specified as similar diary information.
When “b” is described in the similarity field (b> a), the control unit 21 describes the diary information posted by the user of the automatic comment processing service and the “specific target” field. About the diary information whose similarity is higher than “b” among the diary information specified by the information described in the “specification target” field , Specify as similar diary information.
That is, the control unit 21 displays the similar diary information when “a” is described in the “similarity” field than when “b” is described in the “similarity” field. More information is identified.

  The reason why the similarity is set in this way is based on the reason that the phrase or expression used for a certain topic is not fixed to one and often includes so-called fluctuations that do not consider the grammar. Therefore, if a low value is set in the “similarity” field, the specified similar diary information may contain various words and expressions about a topic compared to a high value. Get higher. In addition, if a high value is set in the “similarity” field, compared to the case where a low value is set, the specified similar diary information includes the diary information posted by the user who receives the automatic comment processing service. There is a high possibility that a phrase or expression close to the phrase or expression included in is included.

  Therefore, the server device 20 can specify similar diary information including the expression of a desired phrase by describing a specific condition according to the purpose in the specific condition table TB3 by the administrator of the server device 20. .

(2) Operation In this embodiment, a mode in which a diary poster uses an SNS using the terminal device 30 owned by the diary poster will be described. First, when using the SNS provided by the information management system 1, the user signs a predetermined contract with the SNS administrator. At this time, the SNS administrator issues a user ID and password that uniquely identify the user. Then, the administrator of the SNS operates the operation unit 24 to instruct storage of information such as a user ID and a password. The control unit 21 of the server device 20 describes these user ID and password in association with the user information table TB1 of the storage unit 22 according to the input instruction. For example, in the user information table TB1, as shown in the first line of FIG. 3, “USER01” is described in the “user ID” field, and “PASS01” is described in the “password” field. A user whose user ID is USER01 uses the terminal device 30 to post diary information. That is, the user whose user ID is USER01 posts diary information as a diary contributor.

FIG. 7 is a sequence diagram illustrating operations of the server device 20 and the terminal device 30.
The control part 31 of the terminal device 30 has received the access request to SNS (step S71). And the control part 31 keeps waiting until it detects the access request to SNS (step S71; NO). When the control unit 31 detects an access request to the SNS (step S71; YES), the control unit 31 transmits a message requesting login to the server device 20 (step S72). The message requesting login includes the user ID and password of the diary poster. The control unit 31 stores the user ID in the RAM until the login authentication fails or the SNS is logged off.

  When the control unit 21 of the server device 20 receives the message requesting the login, the control unit 21 extracts the user ID and the password from the message and stores them in the RAM. Then, the control unit 21 determines whether or not a record including the corresponding user ID and password is described in the user information table TB1 as login authentication (step S73). When the control unit 21 determines that the corresponding user ID and password are not described in the user information table TB1 (step S73; NO), it is assumed that the login authentication has failed. In response to this, the control unit 21 transmits information indicating that the login authentication has failed to the terminal device 30. Then, the control unit 31 of the terminal device 30 causes the display unit 33 to display information indicating that the login authentication has failed and the SNS cannot be used (step S74). On the other hand, when the control unit 21 of the server device 20 determines that the record including the corresponding user ID and password is described in the user information table TB1 (step S73; YES), it is assumed that the login authentication is successful. To do. In response to this, the control unit 21 transmits information indicating that the login authentication has been successful to the terminal device 30, and permits the use of the SNS (step S75).

  The control unit 31 of the terminal device 30 controls the display unit 33 to display a list of various services provided by the SNS. Here, the diary contributor operates the operator of the operation unit 34 to select a service for posting diary information. In response to this selection, the control unit 31 transmits a service request for posting diary information to the server device 20. In response to this request, the control unit 21 of the server device 20 transmits screen information for posting diary information to the terminal device 30. The control unit 31 of the terminal device 30 controls the display unit 33 to display a screen corresponding to the screen information. The screen corresponding to the screen information is provided with an input field for inputting diary information corresponding to the “text” of the post management table TB2, for example. Here, it is assumed that the diary contributor inputs “I ate yaba ramen in the cafeteria” by performing a predetermined operation on the terminal device 30 that he owns. When detecting the input, the control unit 31 posts a message including the diary information and the user ID of the diary contributor stored in the RAM to the server device 20 (step S76). Note that the processing from the display of the service list until the completion of input is detected is a well-known processing in the SNS, and is not described in FIG.

  The control unit 21 of the server device 20 extracts the diary information and the user ID from the received message and stores them in the RAM. Further, the control unit 21 stores the current date and time calculated from the timer, for example, “2010.10.10 10:50:00” in the RAM. Then, the control unit 21 describes a new record including the diary information, the user ID, and the current date and time in the post management table TB2 (step S77). More specifically, the control unit 21 sets “USER01” in the “user ID (diary contributor)” field, “2010.10.10 10:50:00”, “ "Diary information body" field "I ate yabai ramen." "User ID (comment author)" field "NULL", "Comment posting date" field "NULL", "Comment information" A new record including information “NULL” in the “text” field is described in the post management table TB2. In accordance with this processing, the record of line number 1 is described in the post management table TB2 shown in FIG.

  Through the above processing, the control unit 21 of the server device 20 can browse the diary information posted from the terminal device 30 operated by the diary poster from another terminal device 30, for example, the terminal device 30 operated by the comment poster. State. In addition, the control unit 21 executes the automatic comment process by executing the posting program PG1 according to a predetermined timing (step S78). Next, an operation when the control unit 21 performs automatic comment processing according to each of the specific condition 1 and the specific condition 2 will be described.

<In case of automatic comment processing according to specific condition 1>
FIG. 8 is a flowchart showing the flow of automatic comment processing performed by the server device 20. When the diary information of the user who receives the automatic comment processing service (the user whose user ID is “USER01”) is posted, the control unit 21 of the server device 20 posts the posting program PG1 stored in the storage unit 22. Is read out, loaded into the RAM, and executed to start automatic comment processing. First, the control unit 21 extracts “specific target”, “specific target period”, and “similarity” corresponding to the specific condition predetermined by the SNS administrator from the specific condition table TB3 (step S81). Here, for example, it is assumed that the administrator of the SNS has designated “specific condition 1” as a predetermined specific condition. The control unit 21 extracts a record in which “specific condition 1” is described in the “specific condition” field of the specific condition table TB3. Then, the control unit 21 stores the information described in the “specific target”, “specific target period”, and “similarity” fields of the extracted record in its own RAM. Here, “electronic diary” as “specific target”, “one month” as “specific target period”, and “a” as “similarity” are associated with records according to “specific condition 1”. This information is stored in the RAM.

  Next, the control unit 21 extracts the diary information corresponding to the specific condition stored in the RAM and specifies it as similar diary information (step S82). Here, since the “specific target” is “electronic diary”, the control unit 21 acquires the user ID “USER01” of the user who receives the service of the automatic comment processing. This user ID has a unique relationship with the electronic diary. That is, among the records included in the post management table TB2, a record including “USER01” in the “user ID (diary contributor)” field satisfies the “electronic diary” as the “specific target”. .

  Then, the control unit 21 stores the current date and time calculated from the timer, for example, “2010.10.10 10:50:05” in the RAM. Then, the control unit 21 stores the date and time one month before the calculated current date and time in the RAM, and the date and time one month before the current date in the “diary posting date and time” field of the records included in the post management table TB2. Extract records that contain the date and time between the date and the present. For example, the control unit 21 extracts the records of the line numbers 2 to 6 of the post management table TB2 shown in FIG. 5 and stores them in its own RAM.

Next, the control unit 21 calculates the similarity between the diary information included in the record with line number 1 that is the target of the automatic comment process and the diary information included in the extracted records with line numbers 2 to 6. To do. Then, the control unit 21 determines whether or not the calculated similarity is higher than the similarity “a”. Here, when the control unit 21 determines that the calculated similarity is “a” or less, the control unit 21 does not specify the diary information compared with the diary information included in the record of the line number 1 as the similar diary information. On the other hand, when determining that the calculated similarity is higher than “a”, the control unit 21 specifies the compared diary information as similar diary information. That is, the control unit 21 compares the text represented by the post information stored in the information storage means with the text represented by the post information to be generated as comment information, and the post information stored in the information storage means. Accordingly, this corresponds to post information specifying means for specifying post information whose similarity to the text represented by the post information to be generated is comment information.
Here, when the number of similar diary information and the specified diary information is 0 (step S83; NO), the control unit 21 ends the automatic comment process without posting the automatic comment information. On the other hand, if the number of similar diary information and the specified diary information is 1 or more (step S83; YES), the control unit 21 comment information posted to the diary information specified as the similar diary information. Is extracted (step S84). Here, the control unit 21 specifies the diary information included in the records with line numbers 3 to 6 as similar diary information, and is further described in the “comment information text” field of the records with line numbers 3 to 6. Comment information is extracted. That is, the control unit 21 corresponds to an extracting unit that extracts comment information for the posted information specified by the posted information specifying unit in the information storage unit.

  Next, the control unit 21 classifies the comment information extracted in the process of step S84 (step S85). For example, the control unit 21 may classify the comment information based on the similarity calculated by morphological analysis which is a well-known technique. Here, it is assumed that the control unit 21 categorizes into “Nothing bad” included in the record at the line number 6 and “Nothing bad” included in the records at the line numbers 3 to 5. In addition, the control unit 21 counts the number of comment information classified, and generates comment information belonging to the classification with the largest number of comments as automatic comment information (step S86). In other words, the control unit 21 counts “Naiyone” as one item and “Yayaiyane” as three items, and identifies “Yayayone”, which is the largest number of counts, as automatic comment information. And the control part 21 converts the produced | generated automatic comment information into a synonym based on the thesaurus which is not shown in figure (step S87). The control part 21 may convert this conversion according to a predetermined algorithm, or may convert it at random. Here, it is assumed that the control unit 21 has converted “Yabayone” into “Great”. That is, the control unit 21 corresponds to a generating unit that converts a phrase included in the comment information extracted by the extracting unit into a synonym and generates automatic comment information including the converted phrase.

  Next, the control unit 21 describes the automatic comment information, the SNS manager ID, and the current date and time generated by the processes in steps S81 to S87 in the post management table TB2 (step S88). More specifically, the control unit 21 sets “USER99 (comment contributor)” to “USER99”, the comment posting date and time “2010.10.10 10:50:05”, and the text “Wow”. Information is described in a record including diary information to be automatically commented in the post management table TB2. That is, the contents included in the record shown in FIG. 9 are described in the record of line number 1 in the post management table TB2 shown in FIG.

  Through the processing described above, the control unit 21 of the server device 20 executes the posting program PG1 so that the automatic comment information can be viewed from another terminal device 30, for example, the terminal device 30 operated by the diary poster. . That is, the control unit 21 can automatically post comment information including a word corresponding to the topic of the diary information posted by the diary poster. That is, the control unit 21 stores the automatic comment information generated by the generation unit in the information storage unit in a state accessible to the terminal device in association with the posting information received by the posting information reception unit. Equivalent to.

<In case of automatic comment processing according to specific condition 2>
Next, automatic comment processing according to the specific condition 2 performed by the control unit 21 will be described. In addition, since the control part 21 implements the process substantially the same as the automatic comment process according to the specific conditions 1, it demonstrates using the flowchart which shows the flow of the automatic comment process which the server apparatus 20 of FIG. 8 performs.

  When the diary information of the user who receives the automatic comment processing service (the user whose user ID is “USER01”) is posted, the control unit 21 of the server device 20 posts the posting program PG1 stored in the storage unit 22. Is read out, loaded into the RAM, and executed to start automatic comment processing. First, the control unit 21 extracts “specific target”, “specific target period”, and “similarity” corresponding to the specific condition predetermined by the SNS administrator from the specific condition table TB3 (step S81). Here, for example, it is assumed that the administrator of the SNS has designated “specific condition 2” as the predetermined specific condition. The control unit 21 extracts a record in which “specific condition 2” is described in the “specific condition” field of the specific condition table TB3. Then, the control unit 21 stores the information described in the “specific target”, “specific target period”, and “similarity” fields of the extracted record in its own RAM. Here, in the record corresponding to “specific condition 2”, “SNS” as “specific target”, “10 years” as “specific target period”, and “b” as “similarity” are described in association with each other. Therefore, these pieces of information are stored in the RAM.

  Next, the control unit 21 extracts the diary information corresponding to the specific condition stored in the RAM and specifies it as similar diary information (step S82). Here, since the “specific target” is “SNS”, the control unit 21 is a record in which all the records included in the post management table TB2 satisfy “SNS” as “specific target”. Then, the control unit 21 stores the current date and time calculated from the timer, for example, “2010.10.10 10:50:05” in the RAM. Then, the control unit 21 stores the date and time 10 years before the calculated current date and time in the RAM, and among the records included in the post management table TB2, the date and time 10 years before the current date in the “diary posting date and time” field. Extract records that contain the date and time between the date and the present. For example, the control unit 21 extracts the records of the line numbers 2 to 10 of the post management table TB2 shown in FIG. 5 and stores them in its own RAM.

Next, the control unit 21 calculates the degree of similarity between the diary information included in the record with line number 1 that is the target of the automatic comment process and the diary information included in the extracted records with line numbers 2 to 10. To do. Then, the control unit 21 determines whether or not the calculated similarity is higher than the similarity “b”. Here, if the control unit 21 determines that the calculated similarity is “b” or less, the control unit 21 does not specify the diary information compared with the diary information included in the record of line number 1 as the similar diary information. On the other hand, when determining that the calculated similarity is higher than the threshold “b”, the control unit 21 specifies the compared diary information as similar diary information.
Here, when the number of similar diary information and the specified diary information is 0 (step S83; NO), the control unit 21 ends the automatic comment process without posting the automatic comment information. On the other hand, if the number of similar diary information and the specified diary information is 1 or more (step S83; YES), the control unit 21 comment information posted to the diary information specified as the similar diary information. Is extracted (step S84). Here, the control unit 21 specifies the diary information included in the records with line numbers 6 to 10 as similar diary information, and is further described in the “comment information text” field of the records with line numbers 6 to 10. Comment information is extracted.

  Next, the control unit 21 classifies the comment information extracted in the process of step S84 (step S85). For example, the control unit 21 may classify the comment information based on the similarity calculated by morphological analysis which is a well-known technique. Here, it is assumed that the control unit 21 categorizes “Sorry I need” included in the records of line numbers 6 to 9 and “Delicious Iy” included in the record of line number 10. In addition, the control unit 21 counts the number of comment information classified, and generates comment information belonging to the classification with the largest number of comments as automatic comment information (step S86). In other words, the control unit 21 counts four “bad” as “one bad” and one “delicious” as one, and identifies “the bad” as the largest number of counts as automatic comment information. And the control part 21 converts the produced | generated automatic comment information into a synonym based on the thesaurus which is not shown in figure (step S87). The control part 21 may convert this conversion according to a predetermined algorithm, or may convert it at random. Here, it is assumed that the control unit 21 converts “not good” to “not good”.

  Next, the control unit 21 describes the automatic comment information, the SNS manager ID, and the current date and time generated by the processes in steps S81 to S87 in the post management table TB2 (step S88). More specifically, the control unit 21 sets “USER99” as the “user ID (comment poster)”, “2012.10.10 10:50:05” as the comment posting date, and “not delicious” as the text. Is described in a record including diary information to be automatically commented in the post management table TB2. That is, the contents included in the record shown in FIG. 10 are described in the record of line number 1 in the post management table TB2 shown in FIG.

  Through the processing described above, the control unit 21 of the server device 20 executes the posting program PG1 so that the automatic comment information can be viewed from another terminal device 30, for example, the terminal device 30 operated by the diary poster. . That is, the control unit 21 can automatically post comment information including a word corresponding to the topic of the diary information posted by the diary poster.

(3) Modifications The contents of the above-described embodiment can be modified as follows. Further, the following modifications may be combined as appropriate.

(3-1) Modification 1
In the above-described embodiment, programs that realize various functions realized by the terminal device 30 and the server device 20 are a magnetic recording medium (magnetic tape, magnetic disk, etc.), an optical recording medium (optical disk, etc.), and a magneto-optical recording medium. It can be provided in a state of being recorded on a computer-readable recording medium such as a semiconductor memory. It can also be downloaded to various devices via a network such as the Internet.

(3-2) Modification 2
In the specific condition table TB3, in the “specific target” field, “Web” other than the service provided by the server device 20 may be described as the specific target. For example, when “Web” is described in the “specification target” field, the control unit 21 determines whether or not information published on the Web is specified as similar diary information. In this way, not only the SNS user's diary information provided by the server device 20 but also information published on the Web is included in the information specified as the similar diary information. Accordingly, the similar diary information is less likely to include uncommon words such as words related to the topic of the diary information and words used by acquaintances.

(3-3) Modification 3
The specific condition described in the specific condition table TB3 is not limited to information corresponding to the diary information such as “specific target”, “specific target period”, “similarity”, but also according to the attribute of the diary poster who posted the diary information. It may be information. The attributes of the diary contributor are, for example, gender, age, residence, origin, blood type, hobby, and the like. The attribute of this diary poster is acquired when a predetermined contract is concluded with the SNS administrator, and is described in the user information table TB1 and the specific condition table TB3. Here, in the specific condition table TB3, the “hobby” that is the attribute of the diary poster is described as the specific condition. In this case, the control unit 21 of the server device 20 specifies the diary information of another diary poster who has the same hobby as the diary poster as similar diary information during the automatic comment process. Therefore, comment information for diary information specified as similar diary information is often posted by a person with the same hobby as the user who receives the automatic comment processing service, and the words and phrases related to the topic of the diary information or the same hobby It is possible to increase the possibility that an uncommon word such as a word used between the two persons is included.

(3-4) Modification 4
In the embodiment described above, the period in which the diary information specified as the similar diary information is posted is limited to the “specific target period”, but the specific target period may not be provided.
(3-5) Modification 5
In the embodiment described above, the automatic comment information specified in step S86 is converted into a synonym based on a thesaurus (not shown) in step S87, but is generated in step S86 without performing the process in step S87. Automatic comment information may be described in the post management table TB2.
