Description

  The present invention relates to a content relationship management system, a content relationship management device, a content relationship management method, and a program.

  Conventionally, when a URL (Uniform Resource Locator) of a Web system is pasted into a mail text and transmitted, the URL displayed on the address bar of the Web browser has been pasted. The URL on the Web system is often meaningless and long for the user, and it is necessary to explain to the other party who receives the mail.

  To solve this problem, there is a URL shortening service that shortens the URL. In order to use the URL shortening service, it is necessary to manually register the original URL and a format obtained by converting it into a shortened form. When the URL shortening service is used, the URL before conversion is designated, and the URL after conversion is designated as necessary. There is also a technique for automatically converting a URL by referring to a URL conversion table stored in advance.

  Patent Documents 1, 2, 3, 6, and 9 describe URL management and provision. Patent Document 1 discloses a shared URL management method in which URL information is shared by a plurality of members of a group and is changed and deleted within the members for management. The shared URL management method disclosed in Patent Document 1 changes additional information related to a URL. Patent Document 2 discloses a URL conversion server system that can accurately and easily access a Web page desired by a user using a keyword. The URL conversion server system of Patent Document 2 stores a keyword and a URL corresponding to the keyword, and provides the user with a URL corresponding to the keyword input by the user.

  Japanese Patent Application Laid-Open No. 2003-228561 discloses a technique that can output which URL contains related WEB information. The technique described in Patent Document 3 automatically searches for links of enormous information on the WEB, and automatically divides each content into categories for each keyword and organizes them. Patent Document 6 discloses a URL processing apparatus that can automatically register a URL in a bookmark without the user performing registration work. The URL processing apparatus described in Patent Document 6 automatically registers in a bookmark based on the number of accesses to the URL read by the user. Patent Document 9 discloses an e-mail search system that can make an ambiguous URL or e-mail address obtained with eyes or ears from TV or radio more reliable. The e-mail search system described in Patent Document 9 includes a database that stores information contents associated with a keyword, and provides the user with an accurate URL and information corresponding to the keyword transmitted by the user by e-mail.

  Patent Documents 4, 7, 8, 10 and 11 describe URL conversion. Patent Document 4 discloses a URL conversion method for converting a URL searched according to a URL search request from a client into an optimum URL according to the user ID, IP address, host name, etc. of the client. The URL conversion method described in Patent Document 4 is searched in order to distribute the load while avoiding concentration of access to a predetermined server, or to return a fast URL according to the position of the client in the network. The URL is converted into a URL corresponding to the environment of the client that issued the search request. Patent Document 7 discloses a URL length conversion system that enables access to a content and a process specified by a long URL exceeding the limit even in a client terminal that is limited in the URL length that can be handled. The URL conversion processing in the URL length conversion system described in Patent Document 7 is reduced to a URL having a length that can be supported by the client terminal.

  Patent Document 8 discloses an access method in which a network URL is accessed through a simplified network address assigned in advance in association with the URL, and a home page having the URL as the network address is displayed. In the access method described in Patent Document 8, the simplified network address assigned to the URL is a number or the like. Patent Document 10 discloses a URL information conversion method in which URL information is divided into a host part and a path part, and unique index information is assigned to each part. In the URL information conversion method described in Patent Document 10, the unique index information assigned to the host part and the path part into which the URL information is divided is a number or the like. Patent Document 11 describes an Internet access technique that allows users to access the Internet simply by inputting a relatively short number corresponding to the URL without making the user aware of the URL of a long and complicated character string. The access technology described in Patent Document 11 assigns a URL expressed in advance as a character string to a relatively short 10-digit number, and the upper 1 digit and the upper 2 to 5 digits correspond to the alphabet and reference value created in advance. Arbitrary numbers are assigned based on a correspondence table of numbers and a correspondence table for the number of digits of the alphabet.

  Patent Document 5 discloses a URL management system that reduces an inconvenience caused when a homepage URL is changed by using an intermediate URL associated with the homepage URL when accessing a homepage searched by a user. Yes. The URL management system described in Patent Document 5 allows an intermediate URL to be passed through when accessing a home page searched by a user, and when access using the intermediate URL is requested, the access destination is converted to the URL of the home page. is there.

  When the URL displayed on the address bar of the Web browser is attached to the e-mail, the URL is long and occupies the content display area. Also, some mail client applications are too long to handle correctly, which is inconvenient.

  On the other hand, when a shortened URL is manually defined using a URL shortening service or the like, the shortened URL is defined for each user of the URL shortening service, and thus, it is disjoint. Since the converted URLs are not consistent, the resulting URLs are not uniform, and there is a high risk of confusion for users. Also, when working in a group, if a specific web page or the like is pasted into the text of an e-mail and sent for reference, uselessness such as introducing the same web page at another time will occur. was there.

  On the other hand, when a shortened URL is automatically defined with reference to a pre-stored URL conversion table, numbers and alphabets are assigned uniformly, and are not shortened based on the original URL. There was no readability. In addition, since the URL after conversion is originally unknown at all, there is a security problem such that the clicked destination is a malicious page. Further, in a Web system in which URLs are redundant, it is necessary to modify the Web system itself in order to make it easy to read a large URL, which is extremely expensive.

  The inventions of Patent Documents 1, 2, 3, 5, 6, and 9 do not convert the URL itself. The URL conversion method described in Patent Document 4 is not intended to shorten the URL. The inventions described in Patent Documents 7, 8, 10, and 11 are not readable because they are not shortened and converted based on the original URL.

A path is a character string indicating the location of a file or directory in a computer file system, and is described by separating it with a slash in a URL.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. In the drawings, the same or equivalent parts are denoted by the same reference numerals.

(Embodiment 1)
FIG. 1 is a block diagram showing a configuration example of a content relationship management system according to an embodiment of the present invention. The content relationship management system 100 includes a content relationship management device 1, a WEB server 2, a DNS (Domain Name System) server 3, a transmission terminal 6, and a reception terminal 7. Content relationship management device 1 and WEB server 2, content relationship management device 1 and transmission terminal 6, content relationship management device 1 and reception terminal 7, reception terminal 7 and DNS server 3, DNS server 3 and content relationship management device 1 are network (Not shown) can communicate with each other. The WEB server 2 may be incorporated in the content relationship management apparatus 1. Although the transmitting terminal 6 and the receiving terminal 7 are representatively illustrated as a single unit, a plurality of transmitting terminals 6 and receiving terminals 7 may be connected to the network.

  The content relationship management apparatus 1 includes a mail receiving unit 11, a URL extracting unit 12, a URL converting unit 13, a mail transmitting unit 14, an information database (hereinafter referred to as an information DB) 15, and a URL correspondence solving unit 16. The mail receiving unit 11 and the mail transmitting unit 14 may be externally connected to the content relationship management apparatus 1 as a mail server.

  The mail reception unit 11 acquires the transmission mail input by the mail sender to the transmission terminal 6 from the transmission terminal 6 and sends it to the URL extraction unit 12.

  When the URL extraction unit 12 receives a transmission mail from the mail reception unit 11, the URL extraction unit 12 extracts a URL included in the transmission mail. If the URL is included in the transmission mail, the URL extraction unit 12 sends the URL extracted together with the transmission mail to the URL conversion unit 13. If the URL is not included in the transmission mail, the transmission mail is sent to the mail transmission unit 14 as it is.

  When the URL conversion unit 13 receives the transmission mail and the URL from the URL extraction unit 12, the URL conversion processing is performed on the URL, and the converted mail obtained by replacing the URL before conversion in the text of the transmission mail with the converted URL is displayed. It is generated and sent to the mail transmission unit 14. Further, the URL conversion unit 13 stores the URL before conversion and the URL after conversion in the information DB 15 in association with each other.

  The mail transmission unit 14 transmits the transmission mail received from the URL extraction unit 12 or the URL conversion unit 13 or the converted mail to the reception terminal 7 of the mail recipient.

  The information DB 15 stores the URL before conversion received from the URL conversion unit 13 and the URL after conversion in association with each other.

  The URL correspondence resolution unit 16 acquires a page display request indicating that the converted URL included in the converted mail received by the mail receiver has been clicked from the receiving terminal 7 via the DNS server 3. The URL correspondence relationship resolution unit 16 searches the information DB 15 for and acquires a URL before conversion corresponding to the URL after conversion included in the page display request. The URL correspondence resolution unit 16 accesses the WEB server 2 using the URL before conversion, and causes the receiving terminal 7 to display the Web page.

  When the WEB server 2 is a computer that transmits information in the WWW system and receives a request to display the Web page corresponding to the URL before conversion on the receiving terminal 7 from the URL correspondence resolution unit 16 of the content relation management device 1. Then, information such as an HTML document or an image of a Web page corresponding to the URL before conversion is transmitted to the receiving terminal 7 through a network such as the Internet.

  When a host name is input, the DNS server 3 is a server that searches for an IP address that identifies the host. The converted URL always includes the host name of the content relationship management apparatus 1. When the converted URL included in the converted mail received by the mail recipient is clicked, the DNS server 3 uses the host name as the original name. The content relationship management apparatus 1 is detected and a page display request is transmitted to the IP address.

  The transmission terminal 6 is a terminal used by a mail sender, and includes a display unit 61 and an input unit 62. The receiving terminal 7 is a terminal used by a mail recipient and includes a display unit 71 and an input unit 72. When the mail sender inputs a transmission mail addressed to the mail receiver in the input unit 62 of the transmission terminal 6, the transmission terminal 6 transmits the transmission mail to the mail reception unit 11 of the content relationship management apparatus 1. When receiving the converted mail from the mail transmitting unit 14 of the content relationship management apparatus 1, the receiving terminal 7 displays it on the display unit 71. When the mail receiver clicks the URL included in the converted mail displayed on the display unit 71 with the input unit 72, the receiving terminal 7 sends a page display request indicating that the URL has been clicked via the DNS server 3. To the URL correspondence resolution unit 16 of the content relation management device 1.

  FIG. 2 is a diagram illustrating an example of URL conversion in the first embodiment. When a URL displayed on the address bar of a Web browser is pasted on an e-mail, it is often a redundant character string as shown in FIG. The content relationship management apparatus 1 converts this into a short character string as shown in FIG.

  FIG. 3 is a diagram for explaining the structure of the URL after conversion. The rear part of “https: //” of the URL after conversion includes <linkserver-address>, <path>, <path-hash>, <pageinfo>, and <pageinfo-hash>. HTTPS (Hypertext Transfer Protocol over Secure Socket Layer) is a communication protocol used for transmitting and receiving contents such as HTML and images between a Web browser and a WEB server, and is SSL (Secure Sockets Layer) or TLS (Transport Layer Security). Security is protected by. Note that the URL may start with “http: //” using HTTP (Hypertext Transfer Protocol) for transmitting and receiving messages in plain text.

  <linkserver-address> is the host name of the content relationship management device 1, and by using the DNS server 3, the content relationship management device 1 can be accessed from the receiving terminal even after URL conversion. Here, a fixed value is used regardless of the URL before conversion. In the example of FIG. 2, it corresponds to “linkserver.example.com”.

  <path> is obtained by shortening the path portion of the URL before conversion to N characters or less, and by leaving the original URL, when the user views the URL after conversion, the corresponding Web site Can be estimated to some extent. In the example of FIG. 2, it corresponds to “server.example.com/top/bts”. In this case, it can be inferred that the URL is any page of the Web site “server.example.com”. The predetermined value N is arbitrarily set by the system administrator. <path-hash> is a character string for avoiding duplication and uniquely identifying a character string of <path> after shortening when it is duplicated with another URL after conversion.

  <pageinfo> is Web page information indicated by the URL before conversion, and is acquired by extracting a part of the Web page according to a predetermined rule. In the example of FIG. 2, it corresponds to “issue list”. Details of the rule for extracting <pageinfo> will be described later. <pageinfo-hash> is a character string for avoiding duplication when the character string of <pageinfo> is duplicated with another URL after conversion, and uniquely identifying it.

  FIG. 4 is a flowchart showing an example of mail transmission operation according to the first embodiment. First, the mail receiving unit 11 receives a transmission mail from the transmission terminal 6 (step S11). The URL extraction unit 12 scans the outgoing mail (step S12), and extracts the URL included in the outgoing mail. For example, a character string “https: //” or “http: //” is detected, and a continuous single-byte alphanumeric character string starting from “https: //” or “http: //” is extracted as a URL. . When the URL is not included in the transmission mail (step S13; NO), the mail transmission unit 14 transmits the transmission mail to the reception terminal 7 (step S16) and ends the process.

  On the other hand, when the URL is included in the outgoing mail (step S13; YES), the URL conversion unit 13 performs URL conversion processing (step S14), and associates the URL before conversion with the URL after conversion. It memorize | stores in information DB15 (step S15). The mail transmitting unit 14 transmits the converted mail in which the URL before conversion included in the transmitted mail is replaced with the converted URL to the receiving terminal 7 (step S16), and ends the process.

  FIG. 5 is a flowchart showing an example of the operation of the URL conversion process according to the first embodiment. The flowchart in FIG. 5 shows the details of the URL conversion process defined in step S14 in FIG. First, the URL conversion unit 13 receives a target URL from the URL extraction unit 12 (step S21). The URL conversion unit 13 determines whether or not the length of the character string of the target URL path is longer than the threshold value N (step S22). When the length of the character string of the path is shorter than the threshold value N (step S22; NO), the URL conversion unit 13 executes a page information acquisition process (step S24). When the length of the character string of the path is longer than the threshold value N (step S22; YES), the URL conversion unit 13 executes a path shortening process (step S23) and executes a page information acquisition process (step S24). Next, the URL conversion unit 13 converts the URL based on the shortened path output in the path shortening process and the page information output in the page information acquisition process (step S25), and ends the process.

  FIG. 6 is a flowchart showing an example of the operation of the path shortening process according to the first embodiment. The flowchart in FIG. 6 shows the details of the path shortening process defined in step S23 in FIG. First, when the length of the character string of the path is longer than the threshold value N (step S31; YES), the URL conversion unit 13 deletes the last segment (portion surrounded by a slash) of the URL (step S32). The URL conversion unit 13 repeats steps S31 and S32 until the length of the path character string becomes shorter than the threshold value N. When the length of the path character string becomes shorter than the threshold value N (step S32; NO), the URL conversion unit 13 shortens the length. It is determined whether or not the character string that has been registered in the information DB 15 (step S33). If the shortened character string is not registered in the information DB 15 (step S33; NO), the URL conversion unit 13 outputs the shortened character string as a shortened path (step S35), and ends the process. If the shortened character string has been registered in the information DB 15 (step S33; YES), a number is assigned so as not to overlap with the registered character string (step S34). Then, the URL conversion unit 13 outputs the shortened character string as a shortened path (step S35) and ends the process.

  FIG. 7 is a diagram showing an example of page information acquisition according to the first embodiment. The page information is obtained by extracting the title tag portion from the HTML (source) of the access destination as shown in FIG. In the example of FIG. 7, “2010 assignment” surrounded by a broken line is acquired as page information. Not only the title tag but also an XPath (XML Path) that extracts a set of parts that meet the condition, a regular expression, or the like can be used to acquire an arbitrary element as page information. For example, as another example, a character string “task list” can be used as <pageinfo> by specifying the name of the div area. In this way, <pageinfo> with high readability can be generated by defining rules according to the Web system.

  FIG. 8 is a flowchart illustrating an example of the operation of the page information acquisition process according to the first embodiment. The flowchart in FIG. 8 shows the details of the page information acquisition process defined in step S24 in FIG. First, the URL conversion unit 13 determines whether or not the server can be accessed using the target URL (step S41). If the server cannot be accessed (step S41; NO), it is output as no page information (step S42). If the server can be accessed (step S41; YES), the URL conversion unit 13 acquires the HTML of the Web page (step S43), and acquires a character string according to the rule (step S44). At this time, a rule such as selecting and acquiring a character string of up to M characters may be set so that the page information does not become long. Next, the URL conversion unit 13 determines whether or not the acquired character string has been registered in the information DB 15 (step S45). If the acquired character string is not already registered in the information DB 15 (step S45; NO), the URL conversion unit 13 outputs the character string as page information (step S47), and ends the process. When the acquired character string is already registered in the information DB 15 (step S45; YES), a number is assigned so as not to overlap with the registered character string (step S46). Then, the URL conversion unit 13 outputs the character string as page information (step S47), and ends the process.

  FIG. 9 is a flowchart showing an example of the URL access operation according to the first embodiment. First, when the converted URL is clicked on the mail receiver input unit 72, the URL correspondence resolution unit 16 receives a page display request from the receiving terminal 7 (step S51). The URL correspondence resolution unit 16 searches the information DB 15 and determines whether there is a URL before conversion of the URL after conversion included in the page display request (step S52). If there is no URL before conversion (step S52; NO), the URL correspondence resolution unit 16 transmits error information indicating that the access has failed to the receiving terminal 7 (step S53), and ends the process.

  On the other hand, when there is a URL before conversion (step S52; YES), the URL conversion unit 13 accesses the WEB server 2 with the URL before conversion (step S54). The URL correspondence resolution unit 16 sends an instruction to the WEB server 2 to display the corresponding Web page on the receiving terminal 7 (step S53), and ends the process.

  As described above, according to the content relationship management system 100 of the present embodiment, it is possible to automatically shorten and convert a URL that is redundant for the user into a URL that is readable. The site can be estimated. As a result, it can be expected that the click destination is a malicious page and the risk is reduced.

(Embodiment 2)
FIG. 10 is a block diagram illustrating a configuration example of the content relationship management system according to the second embodiment. In the content relationship management system 200, a mail display unit 17 is added instead of the mail transmission unit 14 of the content relationship management apparatus 1 according to the first embodiment. In the second embodiment, the mail recipient does not receive and view the mail addressed to himself / herself with the mail application built in the receiving terminal 7 but accesses the content relationship management apparatus 1 from the receiving terminal 7 to view it. The content relationship management device 1 is a kind of mail server. When the mail recipient accesses the mail server from the receiving terminal 7 and refers to the inbox, only the mail specifying information (subject, sender, sending time, etc.) for identifying the received mail is displayed on the receiving terminal 7. The In that state, the text of the received mail is not transmitted to the receiving terminal 7. The second embodiment can be used for, for example, Web mail. The mail receiving unit 11 stores the acquired transmitted mail in the information DB 15 as a received mail addressed to the mail recipient. When the mail recipient accesses the content relationship management apparatus 1 from the input unit 72 of the receiving terminal 7, the mail display unit 17 sends information for identifying the mail recipient to the URL extraction unit 12.

  Based on the information identifying the mail recipient received from the mail display unit 17, the URL extraction unit 12 extracts the mail specifying information of the received mail addressed to the mail recipient from the information DB 15 and returns it to the mail display unit 17. Further, when receiving the mail display request from the mail display unit 17, the URL extraction unit 12 searches the information DB 15 for the received mail addressed to the mail recipient based on the mail specifying information included in the mail display request. Also, the URL extraction unit 12 sends the received mail together with the extracted URL to the URL conversion unit 13 if the URL is included in the retrieved mail. If the URL is not included in the received mail, the received mail is sent to the mail display unit 17.

  Further, when the URL extraction unit 12 receives a mail reference request (for example, “https://linkserver.example.com/server.example.com/top/bts/issue list? References”) from the mail display unit 17, It is determined whether there is a received mail including the URL included in the mail reference request. If there is, a list of received mails including the URL included in the mail reference request is generated and sent to the mail display unit 17.

  When the URL conversion unit 13 receives the URL and the received mail from the URL extraction unit 12, the URL conversion process is performed on the URL, and the converted URL is replaced with the URL before conversion of the received mail to generate a converted mail. And sent to the mail display unit 17. In the second embodiment, the URL conversion unit 13 stores the URL before conversion, the URL after conversion, and the mail after conversion in the information DB 15 in association with each other.
