The computer network 10 is a computer network capable of searching for information resources via a network, such as the Internet.
[0023]
[Operation]
FIG. 2 is an operation flowchart of the first embodiment.
<Step S1>
When the user inputs an activation command, the network information retrieval system is activated. As a result, the data input unit 1 waits for input of user data.
<Step S2>
The user inputs a search sentence, a search start point on the WWW, and a search depth on the WWW.
[0024]
FIG. 3 is an explanatory diagram of the search text input screen.
In this example, a keyword search of information AND filtering is shown. Also, as a search starting point,
http: // www. cs. bham. ac. uk / amg / agents /
And the search depth is 3. Here, http indicates a protocol on the computer network 10, and www. cs. bham. ac. uk represents a machine in the computer network 10, and / amg / agents / represents a hierarchy of a directory in the machine.
[0025]
FIG. 4 is an explanatory diagram of the search start point and the search depth in the information resource having such a hypertext structure.
As shown in the figure, the search start point is the position of the anchor that the user searches first. The anchor is composed of phrase data and link information indicating to which phrase the phrase is linked. Further, the search depth indicates the number of hypertext links that have been traced from the starting point of the search.
[0026]
<Step S3>
Check the syntax of the search statement. In the example, in FIG. 3, when the user presses the “start search” button (clicks with the mouse), the search sentence processing unit 3 parses the search sentence input by the user, and the search sentence syntax is Check for correctness. If the syntax is correct, the search statement processing unit 3 supplies the search statement to the search management unit 4. If the syntax is not correct, the search statement processing unit 3 sends a syntax error message to the user interface management unit 2.
[0027]
<Step S4>
The search management unit 4 instructs the search agent 5 to perform a search starting from a WWW node designated by the user. In the example, the search agent 5 is cs. bham. ac. Find the anchor / amg / agents / of the information resource in the directory in the WWW on the machine uk and copy it to the data storage unit 6.
<Step S5>
The data processing unit 7 searches the information resource obtained in step S4 based on the search sentence.
[0028]
The example of step S5 will be described in detail below.
FIG. 5 is an explanatory diagram of search processing.
The search agent 5 copies the link-destination information resource 2 of the anchor 2 shown in FIG. 5 to the data storage unit 6, and the data processing unit 7 searches the information sentence 2 in the data storage unit 6 for the search sentence “information AND filtering”. Search based on "".
[0029]
At this time, the search is determined by the similarity between the information resource and the search sentence. For example, as an example of the similarity, if at least one character string “information filtering” that is a user's search sentence exists in the information resource, the search target is set. Based on this method, the information resource 2 is recognized as a search target because it includes both information and filtering words.
Similarly, the search is similarly performed for the anchor 5 in the information resource 15 to the anchor 17 in the information resource 15 in FIG. As a result, information resources 2, 3, 4, 5, 7, 8, 13, and 15 indicated by ◎ in FIG. 5 are obtained information resources.
[0030]
<Step S6>
The data processing unit 7 rewrites the link for the information resource in the data storage unit 6. That is, the data processing unit 7 replaces the anchor having the information resource that has not been searched with the original word, and deletes the link information.
FIG. 6 is an explanatory diagram showing this state.
This replaced link is called a local link, and the original link on the network is called a global link.
[0031]
<Step S7>
The data organizing unit 8 organizes data in the data storage unit 6. At this time, for an information resource that cannot be reached by the user's navigation, a link whose direction is opposite to that of the original link is generated.
FIG. 7 is an explanatory diagram when this reverse link is generated.
As illustrated, reverse links are generated from the information resource 8 to the information resource 3 and from the information resource 8 to the information resource 15. A group of information resources connected by links is defined as a cluster. At that time, a node having a small search depth in each cluster is set as a representative of the cluster. Here, in cluster 1, information resource 2 is the representative, cluster2The information resource 4 is representative.
[0032]
<Step S8>
The user interface management unit 2 displays the cluster representative in step S7 to the user as a search result.
FIG. 8 is an explanatory diagram of a search result display screen.
In this case, information resource 2 and information resource 4 are displayed as representatives of clusters 1 and 2. In the drawing, the hypertext anchor is underlined in the drawing, but on the actual screen, the display color is different from that of the other parts, or it is a blink.
[0033]
<Step S9>
If there is a user display request, the data display unit 9 displays the search data in the user data storage unit 6 to the user. In the example, the user can navigate the information resources 5, 7, 8, 3, 15 from the information resource 2 that is representative of the cluster 1. Here, it is possible to navigate from the information resource 8 to the information resource 3 or the information resource 15 by following the generated reverse link. Further, the user can navigate the information resource 13 from the information resource 4 that is representative of the cluster 2.
On the display screen for the user, anchor information for representative 1 and representative 2 is displayed. The user can view the search result by clicking on the anchor information with the mouse. Moreover, when the reverse link is produced | generated like the information resource 8, the reverse link destination is also displayed.
[0034]
FIG. 9 is an explanatory diagram of a display screen of anchor information on which a reverse link is generated. In this case, the information resource 3 and the information resource 15 which are reverse link destinations are displayed together with the anchor information of the information resource 8.
[0035]
<Step S10>
When there is a display request to the global information resource from the user, the link conversion unit 2a replaces the local link with the global link (original link). Thereby, the user can refer to the original information resource. As a result, the user can see two structures: (1) a structure in which search results are organized, and (2) an original hypertext structure. The original hypertext structure data is held in a server (not shown). This server holds information resource data once accessed for a certain period, and the link conversion unit 2a obtains global link data by accessing this server.
[0036]
10 and 11 are explanatory diagrams of display screens for local links and global links.
In the local link, as shown in FIG. 7, the anchor 6 is replaced with the original word, and the link is erased, so that it is not displayed as an anchor. In this state, if the user presses the “Global View” button (clicks with the mouse), the anchors 7 and 5 are replaced with global anchors, and the display is as shown in FIG. In FIG. 11, a global anchor 6 is displayed as a link to the information resource 6 that has not been searched.
[0037]
On the other hand, if the user presses the button “Local View” on the screen shown in FIG. 11, the screen is switched to the screen shown in FIG. In this way, the user can easily switch between the two structures (1) and (2) described above, so that the information resource can be referred to more flexibly.
[0038]
<Step S11>
If the user's search statement is a syntax error, the search statement processing unit 3 informs the user interface management unit 2 that it is a syntax error. The user interface management unit 2 notifies the user through the data display unit 9 that there is a syntax error.
[0039]
[effect]
As described above, according to the first embodiment, when the WWW information search on the Internet starting from the WWW node is displayed as the search result as it is in the WWW information search on the Internet, With regard to the problem of not knowing which information is really good for the user when there is a large amount, it is possible to provide the user with search data organized in a form by collecting nodes connected by hypertext links it can.
[0040]
Also, for nodes that cannot be navigated when putting together hypertext structures, the user can navigate efficiently by generating reverse links.
[0041]
Furthermore, there is a demand for referring to the hypertext structure as a result of the search. In response to such a request, in the first embodiment, since the link structure is replaced with the original structure, the user can refer to the original information resource. Therefore, the user can switch between two structures: (1) a structure in which search results are arranged, and (2) an original hypertext structure, and can refer to information resources more flexibly.
[0042]
<< Embodiment 2 >>
[Constitution]
FIG. 12 is a configuration diagram of the network information search system according to the second embodiment of the present invention.
The illustrated apparatus includes a data input unit 1, a user interface management unit 2, a search sentence processing unit 3, a search management unit 4, a data storage unit 6, a data processing unit 7, a data organization unit 8a, a data display unit 9, and a computer network 10. The database server 11.
[0043]
Here, the database server 11 implements a part of information resources on the computer network 10 as a database. When a search statement is given to the database server 11, information on anchors on the WWW that meets the search conditions is obtained as a search result.
[0044]
The data storage unit 6 stores information resources from the search start point given from the database server 11.
When there is an information resource that cannot be reached in the cluster, the data organizing unit 8a links the information resource and the information resource with the shallowest search depth from the search start point among other information resources. It has a function of generating a virtual node to be connected and outputting the link structure of each information resource as visual data using this virtual node as a representative of the cluster.
Since the configuration other than this is the same as the configuration of the first embodiment, the same reference numerals are given and description thereof is omitted.
[0045]
[Operation]
In the second embodiment, the search management unit 4 supplies a search sentence to the database server 11 of the computer network 10, and the WWW anchor output as the search result by the database server 11 is set as a search start point. In the second embodiment, a case where there are three search start points obtained from the database server 11 will be described.
[0046]
13 and 14 are operation flowcharts of the second embodiment.
<Step S21>
When the user inputs an activation command, the network information retrieval system is activated. As a result, the data input unit 1 waits for input of user data.
<Step S22>
The user inputs a search sentence, a search start point on the WWW, and a search depth on the WWW.
[0047]
FIG. 15 is an explanatory diagram of the search text input screen.
In this example, a keyword search of information AND filtering is shown. Further, the search depth is 3. Here, the definition of the search start point and the search depth is the same as in the first embodiment.
[0048]
<Step S23>
Check the syntax of the search statement. For example, in FIG. 15, when the user presses the “start search” button, the search sentence processing unit 3 performs syntax analysis on the search sentence input by the user according to the syntax of the search sentence of the database server 11. Check that the syntax of is correct. If the syntax is correct, the search statement processing unit 3 supplies the search statement to the search management unit 4. If the syntax is not correct, the search statement processing unit 3 sends a syntax error message to the user interface management unit 2.
[0049]
<Step S24>
The search management unit 4 supplies the database server 11 with the search text input by the user. In the example, the search management unit 4 supplies a search statement “information AND filtering” to the database server 11.
<Step S25>
The database server 11 performs a search based on the search text supplied in step S24.
[0050]
<Step S26>
The database server 11 supplies the searched search result (an anchor of WWW) to the search management unit 4. As a result,
(1) http: // www. blue. umd. edu / enee / medlab / filter / filter. html
(2) http: // www. blue. umd. edu / enee / medlab / filter / filter_project. html
(3) http: // www. xerox. com / PARC / dlbx / filtering. html
Suppose that three anchors are obtained.
Here, all the navigation must be performed based on the search starting point obtained from the database server 11, but also in the second embodiment, the data processing unit 7 collects information resources connected by hypertext structure links, By making a cluster, navigation can be performed efficiently.
[0051]
<Step S27>
The search management unit 4 searches for the search depth specified by the user, starting from the WWW anchor supplied in step S 26, and stores the search depth in the data storage unit 6. The search for each search start point is the same as that in the first embodiment.
16 and 17 are explanatory diagrams showing search results in the second embodiment.
Here, the information resource 1, the information resource 14, and the information resource 21 correspond to the search start points obtained from the database server 11, and the search is performed from each search start point as described in the first embodiment.
[0052]
<Step S28>
The data processing unit 7 rewrites the link for the information resource in the data storage unit 6. That is, the data processing unit 7 replaces the anchor having the information resource that has not been searched with the original word, and deletes the link information.
18 and 19 are explanatory diagrams of the link rewriting process.
Also in the second embodiment, the replaced link is referred to as a local link, and the original link on the network is referred to as a global link. Here, the information resource 5 and the information resource 14 indicate the same information resource searched from different search starting points. The same applies to the information resource 13 and the information resource 21 in FIG.
[0053]
<Step S29>
The user interface manager 2 asks the user whether to visually display the organized hypertext structure. The visual display has the structure shown in FIG. 23, which will be described later. This will be described in detail in step S34 and subsequent steps.
[0054]
<Step S30>
The data organizing unit 8a organizes data in the data storage unit 6. That is, the information resource connected by the link is used as a cluster search result. In this case, a node whose search depth is small (shallow) is used as a representative of the cluster.
20 and 21 are explanatory diagrams of this state.
[0055]
<Step S31>
The data organizing unit 8a generates a virtual node and a virtual link when there are a plurality of representatives for each cluster. For example, in the example shown in FIGS. 18 and 19, there are two representatives of the cluster 1, so the information resource 0 is generated as a virtual node, and links are generated for the information resource 2 and the information resource 3. Then, the generated information resource 0 is set as a representative of the cluster 1. This is the state shown in FIGS.
Here, the information resource 0 is a virtual information resource having only an anchor.
[0056]
<Step S32>
The user interface management unit 2 displays the representative of the cluster in step S31 as a search result to the user.
FIG. 22 is an explanatory diagram of this display screen.
Here, information resource 0 of cluster 1 and information resource 4 of cluster 2 are displayed as anchors.
[0057]
<Step S33>
When there is a user display request, the data display unit 9 displays the search data in the user data storage unit 6.
<Step S34>
The data organizing unit 8 a organizes data in the data storage unit 6. That is, as shown in FIGS. 18 to 21, the information resource to which the link is connected is set as the search result of the cluster.
[0058]
<Step S35>
When there is a user display request, the data display unit 9 displays information resources in the user data storage unit 6 to the user in a hypertext structure.
FIG. 23 is an explanatory diagram showing this state.
That is, each node and its link relationship are visually represented on the display screen. In this case, the data organizing unit 8 a outputs the link structure of each information resource as visual data and stores it in the data storage unit 6. When there is a visual display request from the user, the user interface management unit 2 extracts the data from the data storage unit 6 and outputs it to the data display unit 9.
[0059]
<Step S36>
If the user clicks any node of the hypertext structure displayed in step S35 with the mouse, the data display unit 9 displays information resources related to the user to the user.
<Step S37>
If the user's search statement is a syntax error, the search statement processing unit 3 informs the user interface management unit 2 that it is a syntax error. The user interface management unit 2 notifies the user through the data display unit 9 that a syntax error has occurred.
[0060]
[effect]
As described above, according to the second embodiment, when a user performs a search using the database server 11 on the computer network 10, the user must navigate all search results obtained as WWW anchor information. For the problem, filtering of the hypertext structure and collecting information resources linked by links eliminates the need for the user to navigate through all the information resources, thereby reducing the burden on the user's operation. .
[0061]
In addition, regarding the nodes that cannot be navigated when the hypertext structure is put together, the representative of each cluster is realized by virtual nodes, so that the user can navigate efficiently.
Furthermore, since it is visually displayed, the link relationship between each information resource can be easily understood.
[0062]
In each of the above embodiments, in the first embodiment, the user inputs a search start point and performs a search from the search start point. In the second embodiment, the database server 11 supplies the search start point. Each may have a reverse configuration.
That is, in the system to which the search start point is supplied from the database server 11, the display method may be configured by reverse link. Also, the search start point is not supplied from the database server 11 and the user inputs the search start point. In this configuration, a virtual node may be generated or displayed visually.
[0063]
Further, in each of the above embodiments, the search for the document in the information resource has been described. However, in the image processing, if the search is performed for the content of the image (content), the network information search including the image can be performed. The same can be applied. Further, in each of the above embodiments, the search for information resources on the WWW has been described. However, the search can be similarly applied to searches for information resources having a hypertext structure on other networks.
[0064]
【The invention's effect】
As described above, according to the network information search system of the first and second inventions, information resources connected by hypertext structure links are collected from the searched information resources, and these information resources are defined as clusters. As a result, search data can be provided to the user in an organized manner.
[0065]
According to the network information retrieval system of the third invention, reverse links are generated for information resources that cannot be reached in the cluster, and in the network information retrieval system of the fourth invention, the resource is reached in the cluster. When there is an information resource that cannot be used, a virtual node is generated and the virtual node is set as a representative of the cluster. Further, according to the network information search system of the fifth invention, the link structure of each information resource is visually determined. Since the display is made, the user can efficiently navigate.
