Description

PERSONALIZED VISUALIZATION METHOD FOR SUPPORTING USER'S INFORMATION SEARCH}

The present invention relates to personalized visualization techniques for supporting search sites and web browsing, and in particular, user information adapted to provide a user with a browser a workspace for visually organizing the results of information retrieval and web browsing. A personalized visualization method for supporting search.

Recently, users have tended to utilize information on the Internet for tasks involving high cognitive burden such as information research and learning.

However, since most search engines and browsers provide only simple query-based search and navigation navigation functions to users, the importance of interfaces and technologies to support them is increasing day by day.

The conventional information retrieval method is not suitable for information search support due to the following reasons.

First, it is difficult for users to intuitively know, organize or manage their relationships by visiting a large number of windows and accessing a lot of information in the process of information retrieval and browsing.

Second, when it is necessary to reuse the information already searched, there was a problem that can be accessed only if you visit the memorized pages one by one or register as a favorite.

Accordingly, an object of the present invention is to provide a workspace with a browser for visually organizing the search results and the pages visited (S11) in order to support the user's information search on the Internet.

To this end, it provides a WYSIWYG (WYSIWYG) environment where users can conveniently organize information search results, and at this time, the information can be stored and reused on the user's computer.

In addition, in order to assist the user in organizing the information search results, to extract the topic from the web page and to extract the relationship between the topics.

In addition, it provides information sharing technology that makes the search results available to other users, and technology to use this information for information recommendation for future information search, so that the recommended information can be visually represented in the workspace. It is.

In order to achieve the above object, the present invention provides a method for searching a query input by a user, visualizing the search result or a knowledge space through an expression module, and determining a next progress path by determining a user's command. 1 course; A second step of creating and storing a new topic and occurrence in response to a command input from a user in a search process, connecting a related page under the topic, or creating a relationship between the topics; You can find the file with the occurrence type according to the project command, execute the intersection of two topics, create and save the topic and occurrence, or browse the session information of the pages you visited while creating the topic according to the search command. A third step of performing an inter-spatial command and a search command in the knowledge space according to a selection command such as to make it available; To enable users to get more specific information about their current interests, support with visualization tools and browsers in response to performing new searches or navigating with related links, saving users' previously configured knowledge spaces, ‹It is characterized by a fourth process that allows new access.

According to the present invention, when providing a workspace with a browser to visually organize the results of information retrieval and web browsing to the user, it is possible to support information retrieval and web browsing according to the user's intention more. The effect is expected.

First, the effectiveness of the search results is increased. In other words, by organizing and displaying the pages browsed by users through the visualized tools in the workspace, users can intuitively know the web pages opened by the users and the relationship between the pages. In case of accessing the searched information again in future, various commands are supported so that the effectiveness of the search results can be increased compared to the existing methods.

Second, there is an effect that can reuse the information of the search process in the next information search. That is, in storing and storing search results as a relationship between topics and topics, the information retrieval process and the web browsing process and order are stored together so that the information of the previous search process is searched for next information unlike the case of simply storing a web page. Has the effect of being reused.

Third, the result calculation time is shortened by sharing the search process with others. In other words, by sharing the search process with others based on the information about the previous search process, when multiple users search for the same purpose, the search and browsing process already performed by other users is not duplicated. The time to calculate is shortened.

Fourth, there is an effect of promoting the spread of the semantic web. That is, when the web page using the semantic web is spread, the efficiency of information use of the Internet is maximized, but it is delayed because it is difficult to convert the existing web into the semantic web. However, when using the technology proposed in the present invention, it is possible to build metadata including meanings by searching existing web pages and browsing through hyperlinks of the web pages, thereby promoting the spread of the semantic web. It works.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a client-server network environment to which a personalized visualization method for supporting information retrieval of a user according to the present invention is applied, and a plurality of clients 10A-10N are provided at one side of a communication network 20. Is connected, and the other side has a structure in which the server 30 is connected.

Referring to FIG. 2, a process of a personalized visualization method for supporting a user's information search in the environment as shown in FIG. 1 will be described below with reference to FIG. 2. The following first and second scenarios exemplarily illustrate that the personalized visualization method according to the present invention is applied to an information search task.

[Scenario 1]

If a user is interested in a printer, use his client, for example, client 10A, to enter a "laser ink printer" as a query to find a page about a laser printer on a communication network (Internet) 20. (S1)

Then, the client 10A receives the result of the query from the server 30 and visualizes the data in the workspace 11 in real time through the presentation module. (S2, S3)

Accordingly, the user can recognize a search result for the query word "laser ink printer" input by the user.

Then, the user recognizes that the laser ink printer is different from the laser printer during the search, and then corrects the query for a new search and inputs a new command (S4).

Accordingly, the client 10A determines the modified query, which is the new command (S5), and then repeats the above search process (S1-S3). The visited pages are visualized in real time according to the user's actions in the work space 11 in the form of topics respectively.

The user reads the first few pages of results returned after the new search, notices the page associated with the "laser printer", and enters the topic and occurrence generation commands accordingly. Accordingly, the client 10A determines the topic and occurrence generation command, and generates and stores a new topic and occurrence in response thereto (S4-S6).

The user who has obtained the background knowledge of the laser printer through the above process inputs (or clicks) a trade name as a command to obtain more specific information. Accordingly, the client 10A performs the navigation following the link to view the photograph of the corresponding printer model after determining the brand name. (S4, S5) (S8)

After approximately a few minutes of further navigation, you enter a project command to see all of the linked photos from the page you saved. Accordingly, the client 10A executes a project command (inter-space command) that finds a file having an occurrence type of 'JPEG' after determining the project command. (S4, S5) (S7)

The user who sees the picture through the above process is interested in the product of the company X (hereinafter referred to as 'company X'), and inputs a topic and occurrence generation command for the product. Accordingly, the client 10A determines the topic and occurrence generation command, finds the related page, and connects the related page under the topic “X” (topic and occurrence generation). (S4-S6)

Then, the user gathers additional information about the company X, and inputs a selection command (Select) to view a page related to the laser printer produced by the company X. Accordingly, after determining the selection command, the client 10A executes the inter-space command, that is, the intersection of two topics of “X” and “laser printer”, and creates a topic and occurrence of “Laser printer produced by company X”. Create and store them (S4, S5) (S6, S7)

Finally, client 10A creates a relationship between the two topics “manufactured by” and completes the search process. The knowledge space created in this process is visualized in real time in the workspace 11 and can be easily modified using the provided tools.

The first scenario shows how existing isolated search and browsing behaviors naturally connect on the proposed framework. In particular, the knowledge level and inter-space instructions bridge the gap between information level instructions in a systematic way.

[Scenario 2]

After a few days (e.g. one week), the user decides to order a laser printer among the items examined. At this time, when the user inputs an access command, the client 10A allows the user to access his previously configured knowledge space.

At this time, the user looks at previously configured topics and recalls the information learned during the search. At this time, he recalls the laser printer of company X and inputs the corresponding command, and the client 10A allows the user to select the topic of "the laser printer produced by company X" (S6).

When the user looks at the occurrences of the topic (choose an occurrence), the user finds that the price is considerably higher than he thought, and then decides to visit the previously visited page and compare the price (S6).

By allowing the user to search the session information of the pages visited while creating a topic by inputting a search command (Backward & Forward) as an inter-space command, the users can obtain the information of the visited pages (S7).

This scenario shows how the proposed framework allows users to recycle information they have explored in the past. In the knowledge space of the proposed framework, the user's query, visited page, and newly conceptualized information are visualized in the form of topics and relationships in real time, so that the efficiency of search can be expected.

And these results can be stored and used by the user at any time, and the knowledge space can efficiently support reuse because the user's search process is expressed according to the user's cognitive structure.

In addition, this search process can be used as useful metadata for other users in the future. That is, the data of each user is stored in the user information database 32 of the server 30, so that other users of the user through the browsing information processing module 31B and the question and answer module 31D when browsing and searching for information. Visualize the results in the client (10A-10N).

Topics and relationships organized by users express the meaning of the information. That is, since the semantic structure of the existing information can be obtained in part with the help of users, the effect of the spread of the semantic web can be expected.

Meanwhile, the information search result arranged by the user in the environment as shown in FIG. 1 may be defined in the knowledge space of FIG. 3.

That is, the knowledge space may be expressed as a relationship between a topic and a topic. On the other hand, an information space consists of a set of information objects such as web pages, documents, and images, which also include hyperlinks or directory information of web pages. Searches and browsing that have been done before are possible actions in this space.

The knowledge space resides above this information space and forms a relationship with the objects of the information space through links. The knowledge space reflects the meaning of the information interpreted by the user and expresses its conceptual system with appropriate topics and relationships. In addition, topic types and types of relationships can be defined, so commands for them and ontology are also defined in the knowledge space. This space is built, maintained and maintained through system recommendation and user participation. Information objects are connected by occurrences of topics between the information space and the knowledge space, and support natural connection with each other through inter-space operations. The various commands shown here (eg classification, project, etc.) can be further extended in the future.

A brief description of an example of an instruction that can be made in the space of FIG. 2 is shown in the table below.

Knowledge space commands produce Create topic Create topics that represent one or more information objects Create relationship Create a relationship between two topics Create occurrence Assign Topic to One or More Information Objects
(Create occurrence) delete Delete topic
Delete relationship
Delete occurrence Deleting a Topic, Relationship, or Occurrence Modified Modify topic

Information object acquisition Select Use boolean expressions in the knowledge space to obtain corresponding information objects Project Obtain information objects using occurrences from topics, using specific occurrence types (e.g. PDF or document genre, etc.) Follow
Association Acquire occurrences of neighborhoods on specific topics Backward /
Forward Get previous / next search results Information space command Search Obtain a set of information objects using a query Browsing Use a hyperlink to move to another document

On the other hand, Figure 4 shows the interface of the prototype system as a whole, the left part of the user's workspace. Shown in the workspace (1) are the topics and relationships in the knowledge space. Through the interactions provided by the framework, the search / navigation trajectories made by the browser 4 are extracted first, and they are shown in FIG. 4 through the topic and relationship extraction module. Here, using a manipulation tool like (2), you modify the primarily created topics and relationships and create new knowledge objects. At this time, in order to further reduce the user's cognitive burden, for example, through the modules using the information of the existing knowledge space, for example, the browsing / navigation information processing module 31B, the client visualization and user action processing module 31C in FIG. Recommends routes that users might visit in the future. Additional pages that may be visited will be prioritized in color, with red being the highest priority.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and may be implemented in various embodiments based on the basic concept of the present invention defined in the following claims. Such embodiments are also within the scope of the present invention.
