Description

  The present invention relates to an annotation program, an annotation apparatus, and an annotation method, and in particular, an annotation program that adds an annotation to information based on a request from a user, or acts on information based on a reference request from a user, an annotation The present invention relates to an apparatus and an annotation method.

  In recent years, Web annotations that give annotations as secondary information to information resources (for example, Web pages) on a network such as the Internet or an intranet have come to be frequently used.

  In Web annotation, another third party different from the creator of the Web page gives an annotation such as a tag, underline, or marker to the Web page on the network, and browses the Web page ( (Reference), the added annotation is displayed simultaneously with the Web page, or processing based on the added annotation is added to the Web page.

  Normally, when an annotation is added, a unique name (for example, URL) for the Web page is held, and when the Web page specified by the URL is browsed, the annotation attached to the Web page is restored. An annotation can be restored even when browsing a Web page over time or browsing by a third party different from the annotator with the annotation.

  Conventionally, when an annotation is given to Web page information and the given annotation is shared by a plurality of users, the URL of the Web page on the common server and the annotation given to the HTML file indicated by the URL are displayed. It is common to register the location and contents in a management table.

  When the user designates a URL and requests an HTML file from the Web server, the common server acquires the HTML file from the Web server. Next, the common server refers to the management table, and if an annotation corresponding to the designated URL is registered, the annotation is embedded in the HTML file and transmitted to the user's client. The common server can share the annotation given to the information on the Web page among a plurality of users by doing the above (see, for example, cited document 1).

  Note that the technique described in the cited document 1 targets digital content such as an electronic book, and therefore uses a page identifier and a row identifier to specify the position of the annotation. In other words, the conventional technique is effective when a Web page has a unique URL and the URL does not change over time.

  Conventionally, when annotation is added to a general electronic document, even if the electronic document is updated, if the annotation is displayed in association with the document element at the time of grant, the attached peripheral information is retained, A method is known in which annotation is restored to a document element that approximates retained peripheral information after updating (see, for example, cited document 2).

  In an annotation for a Web page, an article is added and the configuration inside the Web page changes, but the structure does not change. Also, if an article exists in the same URL as when the annotation is assigned, the information (article pseudo-ID) that allows the article to be identified by extracting the article itself or the feature of the article when the annotation is assigned is extracted. The pseudo ID is held together with the URL, contents, and logical position of the annotation.

  The logical position is not a physical position depending on the display such as the XY coordinates, but a character position independent of the display of what character in what paragraph. For example, a typical example is an Xpath (XML Path Language) language that addresses a part of an XML document defined by the W3C.

Rather than simply restoring the annotation to the specified logical position when browsing the Web page, the article having the same pseudo ID is searched from each sibling article, and the annotation is restored to the position corresponding to the moved article. A method is also known (see, for example, Non-Patent Document 1).
JP 2000-155766 A Japanese Patent No. 3755315 IEICE Web Intelligence and Interaction Research Group 20077.7 “How to Match Xpath and Article in What's New Type Web Page”

  By the way, information handled by Web pages on the network is roughly classified into flow type information and stock type information. Blogs and news are examples of flow-type information. A site handling blogs and news has a plurality of articles on a Web page specified by one URL. In some cases, these articles may exist on a Web page specified by a different URL (for example, a Web page having only a single article, a Web page reconfigured by category, month, or the like).

  Also, in a site that handles blogs and news, other articles are added over time, and the configuration within the Web page is changed. When the number of articles in a web page is limited, the article may move to a web page specified by a URL different from the first URL in a format such as “next page”. .

  For this reason, there was a problem that the concept of a page in the technique described in the cited document 1 cannot be used. Moreover, since there is no concept of a line in a site that handles blogs and news, there is a problem that the concept of a line in the technology described in the cited document 1 cannot be used.

  In sites that handle blogs and news, annotations are assigned to articles rather than Web pages themselves. Therefore, in a site that handles blogs and news, even if a copy of an article exists on a Web page specified by another URL, or an article moves to a Web page specified by another URL, When a Web page on which a copy of an article exists is browsed, it has been necessary to display or act as an annotation attached to the article.

  Further, in the techniques described in the cited document 2 and the non-patent document 1, when a copy of the same article exists on a Web page specified by another URL, annotation is performed when browsing the Web page specified by another URL. It was not possible to act on the display. Further, in the techniques described in the cited document 2 and the non-patent document 1, when a copy of the same article is moved to a Web page specified by another URL, the Web page specified by another URL of the destination is moved. Annotation could not be displayed or operated during browsing.

  The present invention has been made in view of the above points. An annotation program, an annotation apparatus, and an annotation method capable of causing an annotation to accurately act on the annotated information even if the position of the annotated information is changed. The purpose is to provide.

  In order to solve the above-described problems, the present invention provides a computer that gives an annotation to one or more pieces of information included in an information resource on a network or acts on the information by a user. An annotation providing means for registering in the annotation management means a first pseudo identifier that specifies information to be annotated based on an annotation grant request, in association with information resource specifying information and annotation information; Based on an information resource reference request, the annotation management means is searched for a second pseudo identifier that specifies one or more information included in the information resource, and the annotation information corresponding to the second pseudo identifier is One or more pieces of information included in the information resource requested by the user Characterized in that it is a annotation program for causing to function as an annotation action means for use.

  In addition, what applied the component, expression, or arbitrary combination of the component of this invention to a method, an apparatus, a system, a computer program, a recording medium, a data structure, etc. is also effective as an aspect of this invention.

  According to the present invention, it is possible to provide an annotation program, an annotation apparatus, and an annotation method capable of causing an annotation to accurately act on the annotated information even if the position of the information to which the annotation is added changes.

  Next, the best mode for carrying out the present invention will be described based on the following embodiments with reference to the drawings.

(Outline of the present invention)
In general, the URL at which a copy of the same article is held or the copy of the same article is moved is not unrelated to the URL of the original article, but is in the same series (the same site, the same directory, etc.).

  According to the present invention, in annotations attached to articles included in a web page on a network such as the Internet or an intranet, there is a systematic article copying / moving which is not performed in a random manner (by human free will) and is not moved. When an article is moved / copied to a URL different from the URL of the Web page with the annotation, the annotation is displayed correctly when browsing the Web page of the copy destination or destination URL, etc. It works.

  For example, in the present invention, assuming that an annotation is added to an article A in a web page with a URL “http: //foo/bar1.html”, browsing a web page with a URL “http: //foo/bar2.html” At this time, when the same thing as the article A is in the web page with the URL “http: //foo/bar2.html”, the article A included in the web page with the URL “http: //foo/bar1.html” The annotation is reflected on the Web page of the URL “http: //foo/bar2.html”.

  Next, sample HTML text will be described. For example, it is assumed that the Web page with the URL “http: //foo/bar1.html” is as shown in FIG. FIG. 1 is an image diagram of an example of a Web page. In the Web page of FIG. 1, articles are divided by a horizontal line, and each article includes a date, title, and article content. 1 is added to the top when a new article is registered. Only a certain number of articles are posted on the Web page in FIG. The web page in FIG. 1 has a link “Previous Page” at the bottom, and an old article is posted at the link destination.

  If an annotation is added to the character string “contents of article 3012” of the article 3012 included in the web page in FIG. 1, the annotation is displayed after the designated character string as shown in the web page in FIG. FIG. 2 is an image diagram of an example of a Web page to which an annotation is given. 2 represents an example in which an annotation is displayed after the character string “contents of the article 3012” of the article 3012.

  Since an article is added to the Web page in FIG. 2 over time, when someone browses it, for example, it looks like the Web page in FIG. FIG. 3 is an image diagram of an example of a Web page to which an article has been added.

  The web page in FIG. 3 has the same URL as the web page in FIG. 2, but articles 3014 and 3015 are added, and the articles 3011 and 3012 posted on the web page in FIG. 2 are “previous page”. It has moved to the linked web page as shown in FIG. FIG. 4 is an image diagram of an example of a linked Web page. For example, it is assumed that the URL of the linked Web page is “http: //foo/bar2.html”.

  In the conventional technology that remembers only the position inside the Web page, the annotation added to the article 3012 is displayed at the article 3014, and what is in the article 3012 whose URL is “http: //foo/bar2.html”. Is not displayed. Further, when considering the movement of an article in a Web page, an annotation is not displayed at the article 3014 with the URL “http: //foo/bar1.html”, but the URL is still “http: // An annotation is not displayed at the article 3012 of “foo / bar2.html”.

  The present invention restores the annotation given to the article 3012 whose URL is “http: //foo/bar1.html” even if the article 3012 moves between Web pages. For example, in the Web page of FIG. 4, when accessing a Web page whose URL is “http: //foo/bar2.html”, an annotation is to be restored to a corresponding position in the article 3012.

  That is, the present invention restores the annotation as shown in the Web page of FIG. FIG. 5 is an image diagram of an example of the annotation restored to the linked Web page. The annotations restored to the Web page in FIG. 5 are physically different in URL and position from those given in the Web page in FIG.

  In FIG. 1 to FIG. 5, for ease of explanation, an article can be uniquely identified by an article number such as “article 3010”, but such an article number is actually given. Instead, normal text is the title, and the title may be the same even if the body is another article.

(Principle of the present invention)
FIG. 6 is an explanatory diagram showing the principle of the present invention. In FIG. 6, when the URL is given, the URL group extraction unit 1 is a Web page on which a copy of the article in the information resource (Web page) indicated by the URL is placed, or an article over time. A set (pattern) of URLs of the destination web page or the source web page is obtained.

  When the annotation retrieval unit 2 is given the set of URLs obtained by the same-system URL group extraction unit 1, the annotation retrieval unit 2 retrieves annotation data given to each URL of the URL group obtained by the same-system URL group extraction unit 1.

  When the same article determination unit 3 is given the annotation data extracted by the annotation extraction unit 2, for each annotation data extracted by the annotation extraction unit 2, an article that can be regarded as the same as the article indicated by the annotation data is currently viewed It is determined whether or not the web page to be present exists.

  The annotation processing unit 4 can be regarded as the same by the same article determination unit 3 when it is determined by the same article determination unit 3 that an article that can be regarded as the same as the article indicated by the annotation data exists in the Web page to be browsed now. For annotation data in which an article exists, the annotation data is applied to a Web page to be browsed now. Here, the action of the annotation data on the Web page to be browsed currently means a process of embedding the annotation data in an appropriate format so that the annotation is displayed on the Web page as additional information, for example.

  As described above, in the present invention, URLs are managed in groups of the same series, and by determining the identity of an annotated article, an annotation is assigned to the copy or movement of the annotated article. It is also possible to make annotations work when browsing a Web page designated by a URL different from the URL of the Web page.

  Further, in the present invention, by having the same article determination unit 3, it is possible to make no annotation given to the disappearance of the original article in the re-browsing of the Web page designated by the URL to which the annotation is added. .

  FIG. 7 is an explanatory view showing another principle of the present invention. FIG. 7 differs from the principle shown in FIG. 6 in that the annotation position is restored. FIG. 6 shows the presence or absence of an annotated article in the URL of the same series when browsing a Web page designated by another URL. Since the configuration of the web page changes, the position in the article to which the annotation has been attached cannot be restored.

  Therefore, in FIG. 7, the annotation position restoration unit 5 is added to the configuration of FIG. The annotation position restoration unit 5 obtains the relative position in the article of the annotation when the annotation is given, and browses from the relative position with respect to the article determined to be the same as the article indicated by the annotation data by the same article determination unit 3 at the time of browsing. The absolute position of the annotation in the Web page to be obtained is obtained.

  Specifically, the annotation position restoration unit 5 can be regarded as the same article when it is determined by the same article determination unit 3 that an article that can be regarded as the same as the article indicated by the annotation data exists in the Web page to be browsed now. The absolute position to which the annotation is given in the Web page to be browsed is obtained from the relative position with respect to the article of the annotation in which the annotation exists, and the absolute position of the annotation is given to the annotation processing unit 4. By having the annotation position restoration unit 5, in the present invention, the position in the article to which the annotation is given can be restored.

  FIG. 8 is an explanatory diagram illustrating another principle of the present invention. FIG. 8 differs from the principle shown in FIGS. 6 and 7 in that the pseudo ID of the article is used as a key. Since the principle shown in FIGS. 6 and 7 uses the URL as a key, it is necessary to determine the same article.

  The article retrieval unit 6 retrieves an article of a Web page that is currently being browsed. The article ID acquisition unit 7 acquires a pseudo ID of the article from the article extracted by the article extraction unit 6. An annotation acquisition unit 8 based on article ID acquires annotation data using the pseudo ID of the article acquired by the article ID acquisition unit 7 as a key. The annotation processing unit 4 causes the acquired annotation data to act on the Web page that is currently viewed.

  As described above, by using an article (pseudo ID) as a key, in the present invention, the determination of the same article and the extraction of a group of URLs of the same series become unnecessary in principle.

  FIG. 9 is a block diagram of an example of a system for realizing the annotation method according to the present invention. The system in FIG. 9 includes an annotation assigning device 10, an annotation management server 20, and an annotation action device 30.

  The annotation assignment apparatus 10 assigns an annotation to a Web page specified by a URL. The annotation management server 20 manages annotations given to Web pages. The annotation operation device 30 operates the annotation when accessing the Web page specified by the URL.

  A typical annotation assigning apparatus 10 is obtained by adding an extended function to a Web browsing device (for example, a browser). The annotation assigning apparatus 10 includes a web page receiving unit 11, an annotation information acquiring unit 12, a logical position specifying unit 13, an article specifying unit 14, an article internal relative logical position acquiring unit 15, an annotation creating unit 16, and an article. The pseudo-ID assigning unit 17 and the annotation transmitting unit 18 are included.

  The web page receiving unit 11 sends a URL to a web server on the network and receives a corresponding web page. The annotation information acquisition unit 12 receives the result of the specification of the fragment in the Web page and the specification of the annotation content by the user. The logical position specifying unit 13 calculates the logical position of the designated fragment in the Web page.

  The annotation creation unit 16 creates annotation data to be stored in the annotation database 22 of the annotation management server 20 from the logical position and annotation contents calculated by the logical position specifying unit 13. The annotation sending unit 18 sends the created annotation data to the annotation management server 20 that manages the annotation database 22.

  Up to this point, the configuration of the typical annotation assigning apparatus 10 has been described. In this invention, it is the structure further including the article specific | specification part 14, the article internal relative logical position acquisition part 15, and the article pseudo ID provision part 17. FIG. The article specifying unit 14 obtains to which article the given annotation is given.

  The article pseudo ID giving unit 17 generates a pseudo ID for specifying an article from the feature information of the article in order to uniquely specify the article, and gives the article pseudo ID to the annotation data. In order to restore the annotation position later, the article internal relative logical position acquisition unit 15 obtains the relative logical position inside the article from the logical position to which the annotation is given, and gives the annotation relative logical position to the annotation data.

  The annotation management server 20 includes an annotation database management unit 21 and an annotation database 22. The annotation database 22 stores annotation data. The annotation database management unit 21 stores and searches annotations with respect to the annotation database 22.

  The typical annotation action device 30 also has an extended function added to the Web browsing device. The annotation operation device 30 includes an annotation extraction unit 31, an annotation operation unit 32, an article specification unit 33, an identical article determination unit 34, an in-series URL group extraction unit 35, a web page reception unit 36, and an annotation position restoration. Part 37.

  The Web page receiving unit 36 fetches a Web page from the Web server when a URL is given. Note that the annotation action device 30 also includes a display unit (not shown) that displays the received web page.

  The annotation retrieval unit 31 inquires the annotation management server 20 about annotation data for the designated URL, and fetches annotation data for the designated URL from the annotation management server 20. In addition, the annotation action unit 32 causes the annotation data acquired from the annotation management server 20 to act on the Web page.

  The most typical action of annotation is to display the contents of the annotation together with the Web page. In that case, the annotation operation unit 32 performs processing of embedding annotation data in a Web page and passing it to the display unit.

  The same series URL group extraction unit 35 extracts a group of URLs of the same series from the given URL. The annotation extraction unit 31 extracts annotation data for each URL extracted as a group of URLs of the same series from the annotation management server 20. The article specifying unit 33 specifies an article included in the Web page for the designated URL.

  The same article determination unit 34 determines whether an article that can be regarded as the same as an article to which annotation data extracted from the annotation management server 20 is included is included in the Web page for the specified URL, and includes articles that can be regarded as the same. The annotation data determined to be received is delivered to the annotation action unit 32.

  In addition, in order to hold the position of the annotation in the article, the annotation position restoration unit 37 compares the relative position of the original annotation within the article and the current web page with respect to the annotation determined to have an article that can be regarded as the same. The position where the annotation is applied is determined from the position of the corresponding article.

  The annotation assigning device 10, the annotation management server 20, and the annotation action device 30 in FIG. 9 are realized by a hardware configuration as shown in FIG. Note that the annotation assigning device 10, the annotation management server 20, and the annotation action device 30 may be realized by separate cases, or may be realized by a single case. In the following description, the annotation assigning device 10, the annotation management server 20, and the annotation action device 30 are collectively referred to as an annotation device.

  FIG. 10 is a hardware configuration diagram of an example of the annotation apparatus. The annotation device includes an input device 51, an output device 52, a drive device 53, an auxiliary storage device 54, a main storage device 55, an arithmetic processing device 56, and an interface device 57 that are mutually connected by a bus B.

  The input device 51 includes a keyboard and a mouse, and is used for inputting various signals. The output device 52 includes a display device and is used to display various windows, data, and the like. The interface device 57 includes a modem, a LAN card, and the like, and is used for connecting to a network.

  The annotation program of the present invention is at least a part of various programs that control the annotation apparatus. The annotation program is provided by distributing the recording medium 58 or downloading it from the network. The recording medium 58 on which the annotation program is recorded is information such as a CD-ROM, a flexible disk, a magneto-optical disk, etc., a recording medium for recording information optically, electrically or magnetically, a ROM, a flash memory, etc. Various types of recording media such as a semiconductor memory for electrical recording can be used.

  When the recording medium 58 on which the annotation program is recorded is set in the drive device 53, the annotation program is installed from the recording medium 58 to the auxiliary storage device 54 via the drive device 53. The annotation program downloaded from the network is installed in the auxiliary storage device 54 via the interface device 57.

  The annotation device stores the installed annotation program and also stores necessary files, data, and the like. The main storage device 55 reads and stores the annotation program from the auxiliary storage device 54 at the time of activation. The arithmetic processing unit 56 implements various processes as described later in accordance with the annotation program stored in the main storage device 55.

(Typical browsing device)
In FIG. 9, the annotation giving device 10 and the annotation action device 30 have been described as being separate. However, in a typical embodiment, one Web browser is provided with both annotation extension and annotation action extension. In such an embodiment, the processing of the browsing device is as follows.

  FIG. 11 is a flowchart showing a processing procedure of a typical browsing device. As a process at the time of browsing, the browsing device first proceeds to step S1 and displays a Web page. The browsing device proceeds to step S2 and accepts a user action. An example of a user action is an annotation assignment request. The user designates a fragment in the Web page by dragging the mouse, right-clicks as it is to display a menu, and selects an item of annotation from the menu. Then, the user makes an annotation assignment request by inputting text as the annotation content. The browsing device performs processing corresponding to the accepted action in step S3 and subsequent steps.

  In step S3, it is determined whether the browsing device has accepted an annotation assignment request. If it is determined that the annotation grant request has been received, the browsing device proceeds to step S4, and performs an action analysis of the accepted action (takes out a mouse dragged fragment or input text and obtains a fragment). In step S5, the browsing device obtains the logical position (Xpath) of the fragment. A specific example of Xpath will be described later.

  In step S6, the browsing device creates an annotation registration (annotation data (record) including the URL and logical position of the current Web page, annotation content, etc.) and sends it to the annotation management server 20 to register it in the annotation database 22. Request). Thereafter, the browsing device returns to the processing at the time of browsing in step S1 to reflect the assigned annotation on the display.

  In addition to the annotation assignment request, the user action includes an action related to an annotation such as annotation deletion, and an action in a general browsing device such as a movement request describing a destination URL in the address field.

(Annotation data example)
The annotation data is managed by the annotation database 22 of the annotation management server 20. FIG. 12 is a configuration diagram of an example of annotation data. The annotation data shown in FIG. 12 includes the URL of the Web page with the annotation, the article pseudo-ID for specifying the article with the annotation, and the annotation indicating where the annotation is added within the Web page. It has a logical position and the content of the annotation. In addition, the annotation data may have incidental information such as an annotation assignment date, an annotation assignor, and an annotation content category.

  For example, in the annotation data of FIG. 12, the second record has a logical position “/ body / div / div / div [2] / div / p / text () of the URL“ http: //foo/bar1.html ”at a certain time. ) [0: 9] ”indicates that the text“ annotation ”has been added as an annotation. Further, when this annotation is given, the article to which the fragment belongs is indicated by the article pseudo ID “34e3fce74489”. Assume that the URL “http: //foo/bar1.html” when the annotation is given is the HTML of FIG.

  FIG. 13 is a configuration diagram of an example of HTML. The tree structure of the HTML shown in FIG. 13 is as shown in FIG. FIG. 14 is a block diagram showing an example of an HTML tree structure. For example, the path to the text of the second article “article 3012” included in the HTML of FIG. 13 is as shown by the dotted line in FIG.

  For example, when the path to the text of the second article “article 3012” included in the HTML of FIG. 13 is expressed in Xpath, “/ body / div / div / div [2] / div / p / text ()” is obtained. The specific position of the annotation further requires an offset in the text (character string), and also requires a start point and an end point. Therefore, the fragment from the 0th character to the ninth character of the body of “Article 3012” is expressed as “/ body / div / div / div [2] / div / p / text () [0: 9]”. . Here, for the sake of simplicity, the start point, the end point, and the offset are expressed simultaneously, but may be expressed separately.

  Note that there is a time difference between the Web page that is being browsed and the Web page when the annotation is added, so it may not be the same. Even if the URL and logical position are the same, the articles are not necessarily the same. Furthermore, in the above example, the article when “http: //foo/bar2.html” is annotated may not be present now.

  FIG. 12 also shows that both the second record and the third record are annotations to the same logical position of the same URL, but are assigned to different articles because the article pseudo IDs are different. In this way, the article pseudo ID is obtained by calculating from the article in order to identify the article, and for example, a hash code of the article (in the above example, the text surrounded by <hr />) is used. . The pseudo ID of the article will be described later.

(Processing when browsing)
The processing of the browsing device at the time of browsing is as shown in FIG. FIG. 15 is a flowchart showing the processing procedure of the browsing device during browsing.

  In step S11, the browsing device is first given the URL of the Web page to be displayed, such as “http: //foo/bar2.html”. In step S12, the browsing device reads a Web page corresponding to the given URL. Up to this point, it is the same as a normal browsing device.

  In the conventional browsing device with the Web annotation function, the annotation data given to the URL specified here is taken out from the annotation management server 20. The browsing device according to the present invention has the same-series URL group extraction unit 35, and in step S13, the main difference is that all annotation data of the same-series group of the specified URL is read.

  For example, in the case where the annotation data is as shown in FIG. 12, in the case of a conventional browsing device, only the record whose URL matches “http: //foo/bar2.html” is read. On the other hand, in the browsing device of the present invention, in addition to the record whose URL matches “http: //foo/bar2.html”, the URL which is a record of a group of URLs of the same series is “http: // foo / bar1. Also read "html" record.

  In the annotation data of FIG. 12, the second, third and fourth records are read. An example of this process will be described later. The browsing device performs the following processing on the annotation data, which is an individual element of the extracted annotation data set.

  In step S14, the browsing device determines whether there is still annotation data extracted from the annotation management server 20 in step S13. If annotation data still exists, the browsing device selects one annotation data.

  In step S15, the browsing device determines whether there is an article with the annotation selected in step S14 on the Web page corresponding to the URL specified in step S11 (whether there is a corresponding article) (same article). Determination unit 34). The details of the article definition and the same article determination unit 34 will be described later.

  If there is a corresponding article, the browsing device proceeds to step S16, and the annotation data is applied to the corresponding article (annotation action unit 32). Details of the annotation action unit 32 will be described later. Progressing to step S17 following step S16, the browsing device returns to step S14 in order to handle the next annotation data extracted from the annotation management server 20 in step S13.

  If there is no corresponding article, the browsing device does nothing with the annotation data selected in step S14. The browser proceeds to step S17 following step S15, and returns to step S14 in order to handle the next annotation data extracted from the annotation management server 20 in step S13.

  In this way, the browsing device determines, for each annotation data of all annotation data in the group of the same series of the specified URL, whether an article corresponding to the annotation data is on the Web page corresponding to the specified URL. To do. If the article corresponding to the annotation data is on the Web page corresponding to the specified URL, the browsing device operates the annotation (annotation operation unit 32). A specific example of the annotation action unit 32 will be described later.

  When the processing of all annotation data is completed, the browsing device proceeds to step S18 following step S14, and displays the web page on which the annotation is applied. Although FIG. 15 shows an example in which a set of URLs of the same series is obtained when browsing a Web page, as another example, a set of URLs of the same series may be obtained when an annotation is given. In this case, a set of URLs of the same series is held together with the annotation data.

  The annotation retrieval unit 31 obtains from the URL to be browsed and the URL at the time when the annotation is pasted instead of matching the set of the same series of URLs to be browsed with the URL when the annotation is pasted. Matching with a set of URLs of the same series is taken.

(Process to read all annotation data of the same series group)
The process at the time of reading all annotations of the group of the same series of the URL to be browsed is as shown in FIG. FIG. 16 is a flowchart showing a processing procedure at the time of reading all annotations of a group of the same series of URLs to be browsed.

  In step S21, the annotation extraction unit 31 receives the URL of the Web page to be displayed. In step S22, the annotation processing unit 31 obtains a group of URLs in the same series with respect to the URL given in step S21. Details of the procedure for obtaining a group of URLs of the same series will be described later.

  A group of URLs of the same series is a set based on URLs. Therefore, a group of URLs of the same series can be expressed in an extended notation (listing all the elements belonging to the set), or an inclusive notation (specifying the conditions that elements to belong to the set must satisfy) ).

  A specific expression of a group of URLs of the same series can be described by a regular expression (pattern expression). The browsing device sends the pattern representation of the group of URLs of the same series to the annotation management server 20.

  The annotation management server 20 proceeds to step S23 and reads the annotation data. Proceeding to step S24, the annotation management server 20 proceeds to step S25 if annotation data still exists. The annotation management server 20 determines whether the URL of the annotation data read in step S23 matches the pattern expression of the URL group of the same series.

  If it matches the pattern expression of the group of URLs of the same series, the annotation management server 20 proceeds to step S26 and leaves the annotation data read in step S23 as a match. If the annotation management server 20 does not match the pattern expression of the group of URLs of the same series, the process proceeds to step S27, and the annotation data read in step S23 is discarded as nonconforming.

  The annotation management server 20 repeats the processes in steps S23 to S27 until it is determined in step S24 that there is no more annotation data. If the annotation management server 20 determines in step S24 that there is no more annotation data, the annotation management server 20 proceeds to step S28 and returns all annotation data of the same series of URLs to be browsed by returning the annotation data left as conformance to the browsing device. Can be returned to the viewer.

  In the flowchart shown in FIG. 16, by fetching URL annotation data that matches the pattern expression of the URL group of the same series, all annotation data of the URL group of the same series can be read.

(Process for obtaining a group of URLs of the same series)
The URL of the group of the same series means a URL where a copy of one article is placed or an article is moved as time passes. In blogs and news, the types of URLs of groups in the same series are almost determined. For example, a directory that is usually one higher than a given URL may be determined as all the following URLs.

  That is, if the current URL is “http: // site name / directory 1 /.. ./Directory n-1 / directory n / file name”, all URLs under “directory n-1” may be used. However, in this case, a URL that is not originally a group of the same series may be mixed.

In order to prevent noise contamination, for example, not all files in all directories but directory names such as cat [1-9] ⁺ /[0-9]*.{html,htm,php} File names can also be constrained by specifying a pattern. In any case, obtaining the URL of the same series more correctly is another technical problem. Note that even if URLs that are not in the same series are mixed, the same article determination unit 34 determines that there is no same article. Therefore, in implementing the present invention, there is only a time loss of making a wasteful determination of the same. It ’s not a big problem.

(Article definition and certification process)
An article is a unit of text. Articles are sometimes called entries in blogs. An article has a date, title, text, contributor, posting date, comment, trackback, permalink, and the like. One example of the article certification process is the separation by rule. In general, a blog has a typical structure. Therefore, certified process article, whether the article advance with any pattern exists with respect to each blog held at regular, cut out articles by referring to the rule. In the example of FIG. 13, it is only necessary to cut out between <hr /> and <hr /> as an article.

  As another example, in a blog created by a tool called “MovableType”, for example, an article has a structure as shown in FIG. FIG. 17 is a block diagram showing an example of the structure of an article. In the example of FIG. 17, for example, the inside of “class =“ entry ”” may be determined as an article.

As another example of the certification process, automatic certification can be performed regardless of individual rules. For example, if there are multiple articles, the structure will be repeated, so you can authorize articles using the repeated structure ("HTML2RSS: Automatic Generation of RSS Feed based on Structure
Analysis of HTML Document "http://www2006.org/programme/item.php?id=p3 etc.).

  In actual operation, if the rule exists, the rule is used, and if it does not exist, integrated processing such as automatic recognition is performed.

(Judgment process for the same article)
In the same article determination process, it is determined whether an article to which an annotation indicated by the annotation data is present is present on the Web page to be browsed.

  One example of determination processing for the same article is the provision of an article pseudo-ID at the time of annotation assignment. In other words, in normal action analysis, fragment logical position calculation, and annotation registration in an annotation assignment action, the browsing device performs processing as shown in FIG. 18 between fragment logical position calculation and annotation registration.

  FIG. 18 is a flowchart illustrating an example of the processing procedure of article pseudo ID assignment at the time of annotation assignment. Proceeding to step S31, the browsing device takes out the article with the annotation. Proceeding to step S32, the browsing device creates an article pseudo-ID from the article with the annotation as described later.

  In step S33, the browsing device adds the article pseudo ID to the normal annotation data and registers the annotation as annotation data. The annotation data has the article pseudo ID by the processing procedure shown in FIG. Note that the article pseudo-ID is not the article ID, but the article ID is created from the feature of the article, whereas the article ID is unique to the article, and the uniqueness is 100% guaranteed. Because it was not done.

  When browsing a Web page, the same article determination unit 34 performs processing as shown in FIG. FIG. 19 is a flowchart illustrating an example of a determination process procedure for the same article when browsing a Web page.

  In step S41, the same article determination unit 34 extracts an article pseudo-ID of an article for which the same article determination process is performed from all annotation data of a group of URLs in the same series as the Web page to be currently browsed. Proceeding to steps S42 and S43, the same article determination unit 34 extracts articles in order from the first article of the Web page to be browsed until there are no more articles, and performs the following processing.

  The same article determination unit 34 proceeds to step S44, and obtains the article pseudo ID of the extracted (attention) article. Proceeding to step S45, if the article pseudo ID obtained in step S44 matches the article pseudo ID extracted from the annotation data in step S41, the article of interest is the same as the article indicated by the annotation data. It can be considered.

  Therefore, if the article pseudo ID obtained in step S44 matches the article pseudo ID extracted from the annotation data in step S41, the same article determination unit 34 proceeds to step S48, and the article is displayed on the Web page to be browsed now. It is determined that there is an article indicated by a pseudo ID.

  If they do not match, the same article determination unit 34 proceeds to step S46 and proceeds to processing of the next article because the article of interest is different from the article indicated by the annotation data. The same article determination unit 34 extracts articles in order from the first article of the Web page that is currently being browsed until there are no more articles, and then proceeds to step S47, and the article indicated by the article pseudo ID is currently displayed on the Web page that is currently being browsed. Judge that there is no.

(Article pseudo-ID acquisition processing for articles)
The article pseudo ID acquisition process of an article is to obtain an article pseudo ID from the feature information of the article in order to determine the identity of the article. The simplest method is to use the entire article or a character string of the title as the article pseudo ID. However, the method of using the entire article or the character string of the title as the article pseudo-ID increases the capacity of the article pseudo-ID, and it takes time to determine the identity.

Therefore, normally, as an article pseudo-ID acquisition process for an article, the entire article or a part of a character string is digitized by a hash code. As other article pseudo-IDs, date / time information when an article is posted can be used. The permalink of each article can also be used as an article pseudo ID. A permalink (fixed link) is a URL provided for each article in a Web page.

(Annotation processing)
The annotation action unit 32 causes the annotation data to act on the corresponding article. The annotation data has at least the URL of the Web page with the annotation, the article pseudo ID for specifying the article with the annotation, and the annotation content. Further, when restoring the position of the annotation, it has a logical position as a position where the annotation should act.

  A typical example of the action of annotation data on an article is an additional display of annotation data. In this case, to operate the annotation data means to create a display web page in which the data indicated by the annotation data is embedded at an appropriate position of the web page, and finally to the web page in which the annotation data is embedded. To display. As another example of the action of annotations on an article, there is a Web page such as metadata embedding that has side effects (such as changing the display color or size).

  FIG. 20 is a flowchart illustrating an example of the annotation processing procedure. Proceeding to steps S51 and S52, the annotation action unit 32 sequentially extracts the annotation data of the articles determined to be in the Web page to be browsed currently by the same article determination processing until the articles disappear.

  When the annotation data is extracted, the annotation operation unit 32 proceeds to step S53, and obtains the actual position on the Web page from the logical position included in the extracted annotation data. In step S54, the annotation action unit 32 determines whether the type of the extracted annotation is for display or other types.

  If the extracted annotation type is for display, the annotation operation unit 32 proceeds to step S55 and creates an HTML fragment for display. In step S56, the annotation action unit 32 embeds the created display HTML fragment in the temporary display HTML, and creates a display Web page in which the data indicated by the annotation data is embedded at an appropriate position of the Web page.

  Note that the annotation action unit 32 sequentially extracts the annotation data of the articles determined to be on the Web page to be browsed by the same article determination process until no longer exists, and then proceeds to step S57 to display the temporary display HTML. The web page in which the annotation data is embedded can be displayed by passing it to the section.

(Annotation position restoration processing)
In order to restore the position of the annotation inside the article when the annotation is given, the article with the annotation is specified and the annotation is assigned to the article where the annotation is given. The logical position within the article at the selected position is obtained, and the logical position is recorded as annotation data together with the URL of the Web page with the annotation, the article pseudo-ID of the article with the annotation, and the content of the annotation.

  When browsing the Web page, when restoring the annotation, the logical position of the article is extracted from the annotation data, the location of the logical position of the corresponding article is obtained, and the location is set as the action position of the annotation. FIG. 21 and FIG. 22 are configuration diagrams of an example representing an HTML tree structure.

  For example, in the example of the tree structure in FIG. 21, if an article between <hr /> and <hr /> is defined as “/ body / div / div / div [2] / div / p / text ()”, Articles range from "/ body / div / div / hr [2] /" to "/ body / div / div / hr [3] /" shown by dotted lines. Therefore, the logical position of the annotation in the article is “div / div / p / text ()”.

  Therefore, in the example in which the article 3012 has moved to “http: //foo/bar2.html”, after the position of the article 3012 is recognized, for example, the position where the annotation should be added using the logical position indicated by the dotted line in FIG. Can be determined. The calculation of the logical position in the annotation position restoration process is performed, for example, according to the processing procedure shown in the flowchart of FIG. FIG. 23 is a flowchart illustrating an example of a processing procedure for calculating a logical position.

  In step S61, the annotation position restoration unit 37 first obtains the upper node of the article range from the article pattern. In the example of FIG. 21, since the range delimited by <hr /> is recognized as an article, the Xpath of the upper node of the article range is “/ body / div / div”.

  In step S62, the annotation position restoration unit 37 obtains the Xpath of the annotation. In the example of FIG. 21, “/ body / div / div / div [2] / div / p / text ()” is obtained as the Xpath of the annotation. In steps S63 and S64, the annotation position restoration unit 37 traces the annotation Xpath “/ body / div / div / div [2] / div / p / text ()” one by one until it goes out of the article range. In this example, it reaches "/ body / div / div".

  If it goes out of the article range, the annotation position restoration unit 37 proceeds to step S65, and obtains an article range including the annotation from the article pattern (a part surrounded by a dotted line). Then, the annotation position restoration unit 37 obtains Xpath within the article range from “/ body / div / div”, which is the current position, to the annotation position.

  In the example of FIG. 21, Xpath within the article range from “/ body / div / div”, which is the current position, to the annotation position is “div / div / p / text ()”. In addition, it is “div [2] / div / p / text ()” because it is the second “div” in the entire range from the upper node, but this is because it becomes the first “div” when limited to the article range. Become.

  The example in which the annotation logical position is stored in the annotation database 22 has been shown so far, but it is better to store the relative logical position within the article in order to restore the annotation position. When the relative logical position is stored, the annotation data becomes as shown in FIG. FIG. 24 is a configuration diagram of an example of annotation data when relative logical positions are stored. Actually, annotations to fixed parts other than articles can be considered. For such annotations, the logical position is retained.

  The annotation position is restored from the relative logical position by, for example, the processing procedure shown in the flowchart of FIG. FIG. 25 is a flowchart illustrating an example of an annotation position restoration process procedure from a relative logical position. In the annotation position restoration process from the relative logical position, the annotation position is restored from the recognized article and the relative logical position.

  In step S71, the annotation position restoration unit 37 obtains the upper node “/ body / div / div” of the article. In step S72, the annotation position restoration unit 37 obtains the first child node from the relative logical position and the article range. The annotation position restoration unit 37 follows the tree structure according to the Xpath of the relative logical position from the upper node of the article.

  At that time, the annotation position restoration unit 37 follows the first child node as a relative logical position within the certified article range. In the example of FIG. 21, the upper node of the article is “/ body / div / div” and the relative logical position is “div / div / p / text ()”, but the first “div” from the article range is As a whole, the first “div” is requested, and the subsequent steps are followed in order to arrive at “/ body / div / div / div / div / p / text ()”. The annotation position restoration unit 37 proceeds to step S75 and sets the place where the annotation is reached as a restoration place.

(Summary)
The present invention calculates and has information (article pseudo-ID) for specifying an article from the article contents in order to correspond to the annotation of the flow type information, but it is possible to move across pages and copy to related pages. In order to cope with the above, it is important to collect not only the annotations assigned to the specified URL but also all annotations of the same series of URLs to be browsed. However, since the position of the annotation cannot be restored only by this, the present invention enables the restoration of the position of the annotation by managing the position of the annotation not by the position depending on each URL but by the relative position in the article.

  In the first embodiment, an example in which all annotations (related annotations) of a group of the same series of URLs to be browsed are extracted using the URL to be browsed as a key, but as another example, an article pseudo ID is used as a key. As well as related annotations.

  The processing of the browsing device at the time of browsing is as shown in FIG. FIG. 26 is a flowchart showing the processing procedure of the browsing device during browsing.

  In step S81, the browsing device is first given the URL of the Web page to be displayed, such as “http: //foo/bar2.html”. In step S82, the browsing device reads a Web page corresponding to the given URL. In steps S83 and S84, the browsing device sequentially extracts articles in the read web page.

  Proceeding to step S85, the browsing device obtains an article pseudo ID of the extracted article. In step S86, the browsing device requests the annotation management server 20 to extract annotation data using the article pseudo ID obtained in step S85 as a key.

  If there is annotation data corresponding to the article pseudo-ID, the annotation management server 20 passes one or more annotation data corresponding to the article pseudo-ID to the browsing device. Proceeding to step S87, when the annotation data corresponding to the article pseudo-ID is passed, the browsing device proceeds to step S88, where the annotation data is applied to the corresponding article, and then returns to step S83. If the annotation data corresponding to the article pseudo-ID is not passed, the browsing device directly returns to step S83. Note that the method of causing annotation data to act on the corresponding article is the same as in the first embodiment.

  When the processing is completed for all articles in the read web page, the browsing device proceeds to step S89 following step S84, and displays the web page on which the annotation is applied.

  For example, assume that a Web page represented by HTML in FIG. 27 is read with respect to a given URL “http: //foo/bar2.html”. FIG. 27 is a configuration diagram of an example of HTML. The browsing device recognizes between <hr /> and <hr /> enclosed by the dotted line in FIG. 27 as an article, and cuts out the part enclosed by the dotted line in FIG. 27 as an article.

  The browsing device calculates the article pseudo ID “34e3fce74489” from the extracted article, and takes out the annotation data from the annotation database 22 using the article pseudo ID “34e3fce74489” as a key. For example, in the case of the annotation data in FIG. 24, the URL “http: //foo/bar1.html”, the article pseudo ID “34e3fce74489”, and the relative logical position “div / div / p / text () [0] that configure the second record. : 9] Since the annotation content “annotation” is found, the browsing device causes the annotation data to act on the Web page as described above, and then displays the Web page.

(Summary)
The present invention calculates and has information (article pseudo-ID) for specifying an article from the article contents in order to correspond to the annotation of the flow type information, but it is possible to move across pages and copy to related pages. In order to cope with the above, annotations in units of articles are made possible by directly searching for article pseudo IDs without specifying the same series group of URLs to be browsed.
