Description

Technical Field [0001] The present invention relates to a tile-based knowledge visualization apparatus and method,

The present invention relates to a knowledge service apparatus and method, and more particularly, to a knowledge visualization apparatus and method using a knowledge visualization technique considering characteristics of a map and a tree based on a tile object.

Wikipedia, a leading online encyclopedia, has a wealth of knowledge, which allows anyone to update their knowledge, and provides a way to search for relevant knowledge through keyword search and links within the page. Naver's intellectuals (in), like Wikipedia, enable anyone to register and explore knowledge that includes text, images, audio, and video.

However, the knowledge services as described above can search for knowledge by a word level keyword selected by the user in order to retrieve necessary information. In addition, the search results are not arranged at a level that the user can immediately understand, but are often provided only as text lists.

Therefore, if the user does not have an immediate understanding of the search results, he or she should search additional knowledge to help understand. To do this, the user has to search through a vast amount of related knowledge links, or re-search using new keywords. In addition, the knowledge search result output based on the text is not effectively represented in the association of knowledge.

In order to solve the problems of the conventional knowledge service described above, various techniques for visualizing the retrieved results have been proposed. For example, map-based visualization techniques such as topic maps, concept maps, and mind maps, and tree-based visualization techniques based on keywords or category classification have been provided in various variations according to service objectives.

However, the above-described visualization techniques are not easy to visualize the interrelationships of knowledge, and the structure is so complex that knowledge visualization is not provided in a form in which anyone can intuitively search for and access knowledge.

In particular, despite the wide variety of visualization views that can be applied, depending on the purpose of the service and the characteristics of the user, existing technologies are being provided with a single type of view. That is, an existing visualized view can not easily be converted into another type of view according to a service and a user's request.

In addition, when a user having a relatively low level of understanding of a specific knowledge approaches a particular knowledge service for learning purposes, the conventional knowledge search is not easy to search because it must undergo various stages of searching such as a text-based knowledge search .

The present invention provides a tile-based visualization apparatus and method that combines a map and a tree to visualize content data included in a knowledge hierarchy and knowledge.

The present invention relates to a tile-based knowledge visualization method comprising the steps of: constructing a lattice space composed of one or more tiles which is a basic unit of output of knowledge information; Setting at least one tile according to the set reference information, and outputting the tile to a screen.

The present invention relates to a tile-based knowledge visualization apparatus, which comprises a user input unit for receiving an interaction signal from a user, a display unit, an interaction analysis unit for analyzing an interaction signal inputted by the user input unit, A tile generating unit configured to generate at least one tile that is a basic output unit of the tile generating unit, a tile generating unit configured to form a lattice space composed of one or more tiles, setting reference information to be arranged in rows and columns of the lattice space, A tile-based interface screen forming unit for arranging at least one tile generated by the tile generating unit and outputting the tile-based interface screen to the display unit; and a tile-based interface screen displayed on the display unit in a user interaction signal analyzed by the interaction analyzing unit, And an interaction performing unit for changing the interaction.

According to the present invention, a single object called tile is used, and a complex knowledge is easily visualized by arranging a lattice column based on a lattice type layout according to the characteristics of knowledge and contents data.

In the present invention, the hierarchical structure of the knowledge and the area for visualizing the content data included in the knowledge are separately used in the form of a tree and a map, respectively, according to the amount of information to be outputted. Therefore, And the screen configuration can be kept uncomplicated.

In addition, according to the present invention, since a tile object having the same shape as a generalized output screen called a rectangle is used as a basic unit of visualization, each region can be freely transformed according to a service request or integrated into one region and output as various view screens Do.

In addition, since the present invention has a structure for visualizing content data included in a hierarchical structure of knowledge and knowledge, it is possible to use other fields having similar structures and characteristics as those of the present invention, for example, Output, and output of structured web pages such as Wiki.

Here, knowledge refers to information that has been refined and verified for various contents sporadically generated by various purposes in various fields of society, and reworked so that users can easily acquire it. In addition, the content means text, image, audio, video, 3D, documents of various formats, etc., provided with knowledge.

1 is a view illustrating a tile and a tile lattice space according to an embodiment of the present invention.

Referring to FIG. 1, a tile is a basic output unit having a name independent of the model and having a rectangular shape capable of interacting with a user.

According to one embodiment, the tile comprises a rectangular outline, a background color, and a label. The label indicates the information about the knowledge linked to the tile, and may include the name of the knowledge information, the registration date, and the identifier (ID).

The lattice space is a virtual space of a two-dimensional plane having rows and columns, and the lattice space is formed of a space in units of cells divided by horizontal and vertical dividing lines arranged at regular intervals in a two-dimensional plane space. According to one embodiment, only one tile can be placed in one cell. In addition, one of the rows and columns constituting the lattice space is marked with a classification criterion for the placement of tiles. For example, the classification criteria may be displayed in the first row and the first column.

FIG. 2 is a diagram showing an example in which a classification criterion is displayed in a lattice space according to the present invention.

Referring to FIG. 2, one of the rows and columns constituting the lattice space is displayed with reference information, as described above. According to an embodiment of the present invention, the reference information has two formats, one of which is a reference information that can be classified, such as a format of a file or category information based on a classifiable domain. The other is an indexable sorting reference, in which sortable reference information such as an index number, a date, a version, and the like is arranged.

For example, knowledge domain information serving as a classification criterion of tiles is arranged in each column of the lattice space, and an index number for aligning the tiles is arranged in each row. In addition, the sorting criterion and the sorting criterion arranged in the rows and columns of the lattice space can be switched from one another to another. In other words, contrary to that shown in Fig. 2, a row-breakable property can be placed and an attribute that can be arranged in a column can be arranged. It is possible to set which classification criterion is placed in rows and columns by user interaction.

Here, the classifiable attribute may include a knowledge hierarchy expressing a hierarchical relationship of knowledge, a knowledge unit expressing a relation between a definition of knowledge and knowledge, and a plurality of contents delivered through the knowledge unit.

3 is a block diagram of a tile-based knowledge visualization apparatus according to an embodiment of the present invention.

Referring to FIG. 3, the tile-based knowledge visualization apparatus includes a user input unit 110, an interaction analysis unit 120, a tile-based interface screen configuration unit 130, an interaction execution unit 140, a tile generation unit 150, And a display unit 170. The display unit 170 includes a display unit 170 and a display unit 170. [ In addition, it further includes a knowledge DB (180).

The user input unit 110 is a means for receiving an interaction signal from a user, and is all possible input means such as a keypad, a mouse, and the like. Although the user input unit 110 and the display unit 170 are shown as being separated from each other, the user interface 110 and the display unit 170 may be integrated into a user interface such as a touch screen.

The interaction analyzing unit 120 analyzes the interaction information input by the user input unit 110, converts the interpretation information into a knowledge visualization request query, and outputs the query. The interaction according to the present invention may include a tile-based interface screen setting request, a tile level change request, a tile selection / non-selection request, a tile link content information output request, a tile-related lower layer tile output request,

The tile-based interface screen constructing unit 130 configures the grid space shown in FIG. 2 as described above. The tile-based interface screen constructing unit 130 analyzes a user interaction inputted through the user input unit 110 to set a classification criterion, Let the tiles follow. The tile-based interface screen arranged in this way is rendered through the rendering unit 160 and output through the display unit 170.

The interaction performing unit 140 creates and changes visualized screen configuration information such as the placement position of the tiles generated by the tile generating unit 150 in the lattice space configured by the tile based interface screen forming unit 130 according to user interaction . For example, the tiles arranged in the lattice space and the lattice space can be enlarged or reduced in size according to the user's interaction. In addition, rows and columns of lattice space can be inserted, deleted, merged, and partitioned. Also, the output information of the tile has a level or a depth. That is, the amount of information output to the tile can be adjusted according to the output level given to the tile. Such user interaction will be described in detail with reference to FIGS. 4 to 9C.

The tile generation unit 150 generates tiles by acquiring knowledge information to be output in the form of tiles from the knowledge DB 180 according to the knowledge visualization request query transmitted from the interaction execution unit 140. Here, the tile generating unit 150 may be provided internally or may be connected to the outside through wired / wireless communication means.

The rendering unit 160 receives the visualization screen configuration information transmitted from the interaction performing unit 140 and performs rendering of the visualization screen configuration information in a form that can be outputted through the display unit 170. [

The display unit 170 is a viewer that provides a tile-based knowledge visualization screen rendered by the rendering unit 160 to a user.

Based on the tile-based knowledge visualization apparatus having the above-described configuration, the user interaction is reflected on the tile-based screen according to the user interaction, will be described with reference to FIGS. 4 to 9C.

4 is a view for explaining a tile level adjustment interaction according to an embodiment of the present invention.

Referring to FIG. 4, the output level of the tile can be controlled through user interaction of zooming. That is, if the level 1 tile is expanded to level 2 according to the user interaction, only the label is displayed in the tile at the level 1, and the knowledge of the tree type is displayed in the tile at the level 2. That is, as the size of the tile increases, a larger amount of knowledge can be output.

5 is a view for explaining a tile selection interaction according to an embodiment of the present invention.

Referring to FIG. 5, the location of a cell in which a tile is to be arranged is determined based on reference information set in rows and columns of the grid space. In addition, the tiles arranged in the lattice space have two states, active and non-active according to the user's selection. In the case of the non-selected tiles, the style information of the tiles is changed to the non- And the sub information of the corresponding tile is not output until there is a separate user request. For example, among the tiles in the knowledge hierarchy column of FIG. 5, the user does not select the 'molecular motion of the material' so that the background color of the tile is processed differently from the selected tile.

FIG. 6 is a diagram illustrating detailed information of a tile in a lattice space according to an exemplary embodiment of the present invention. Referring to FIG.

The tile includes information constituting knowledge as an attribute. For example, as shown in FIG. 6, the knowledge associated with the textbook can be output. When a user wants to check specific information by selecting a specific tile and performs a user interaction with a predefined tile such as a double click or swipe of the tile, detailed information about the tile is displayed in a grid space (Tool tip) in the adjacent position of the ball.

For example, in FIG. 6, the details of the content 'solid = liquid-gaseous .jpg' included in the knowledge unit 'liquid' belonging to the knowledge classification system 'three states of matter' The information is output to the right side of the tile in the form of speech bubbles.

This detailed information output does not affect the basic screen layout composed of tiles. That is, an area corresponding to the number of cells sufficient to output detailed information on a basic screen composed of tiles is selected and used. That is, unlike a tile, detailed information can use a cell space of a predetermined size according to information to be output without using only one cell space. For example, a textbook or knowledge hierarchy uses two cell spaces, while a content uses six cell spaces.

7A-7E illustrate a tile-based knowledge structure and content output in a lattice space in accordance with an embodiment of the present invention.

Referring to FIG. 7A, when the user performs predetermined interactions with respect to the 'one science' tile disposed in the 'textbook' column in the grid space, the knowledge hierarchy information associated with the textile tile is' Is output as a tile in the knowledge hierarchy column of FIG.

Referring to FIG. 7B, when an interaction is performed in a tile belonging to the knowledge hierarchy of 'state of matter' in the 'knowledge hierarchy' column, the unit information of knowledge related to the knowledge hierarchy is' Knowledge unit 'column. And the unselected 'molecular motion of material' tile is unselected.

Referring to FIG. 7C, when an interaction is performed in a tile belonging to a knowledge unit 'state of matter' in the 'knowledge hierarchy' column, contents associated with the knowledge unit are sequentially output in a map form on the right side of the tile.

Referring to FIG. 7D, contents output by adding a content column and reference information can be classified according to a file format and output.

As shown in FIGS. 7A and 7B, tiles are arranged while maintaining a hierarchical structure of a tree form up to the knowledge hierarchy and the knowledge units, and in the case of contents, according to the position of the knowledge unit tile and the reference information of the column The tiles are arranged in a tree or map form.

In addition, if the number of contents to be output is large as shown in FIG. 7E, the user can output a content by merging a plurality of columns through setting.

8A and 8B are diagrams illustrating output results filtering by user interaction in accordance with the present invention.

In the example of the 'textbook' as described above, when the user wishes to check only the knowledge unit and related content information excluding the knowledge hierarchy information, the output screen can be easily changed by deleting the 'knowledge hierarchy' column as shown in FIG. 8A have.

Likewise, if it is desired to check other textbook information related to the textbook in the 'textbook' column currently used by the user, the 'service target' column is added to the left side of the textbook column as shown in FIG. .

FIGS. 9A to 9C are views for explaining the basic inter-knowledge relationship of tile-based knowledge visualization according to the present invention.

Knowledge, like a link on a web page, can have one or more relationships with other knowledge. These relationships can be defined in various forms according to service objectives. For example, in order to understand a knowledge Y, there may be a prior knowledge X that needs to be learned first before acquiring knowledge Y. At this time, knowledge X becomes a prior knowledge of Y, and knowledge Y becomes a follow-up knowledge of X.

In order to output these association relations to the tile-based visualization view, it is possible to support visualization of knowledge-to-knowledge association according to the output example of the tile as described above.

For example, as shown in FIG. 9A, the knowledge related to the knowledge currently selected in the tree-based knowledge area can be specified and displayed in a separate color. In FIG. 9A, it can be seen that the liquid and gas in the knowledge area are displayed differently from the other tiles with the solid follow-up knowledge.

Also, as shown in FIG. 9B, the relationship of the currently selected knowledge can be visualized in a different form such as a content map by using the detailed information output form of the tile.

Finally, as shown in FIG. 9C, the area for outputting the structure of knowledge can be expanded to output the knowledge related to the selected knowledge in the reverse order. In FIG. 9c, the knowledge structure of the knowledge of the trailing knowledge of the currently selected 'solid' is outputted in the tree form in the reverse order to the right of the screen to provide a structure of the trailing knowledge so that it can be easily recognized.

10 is a flowchart illustrating a tile-based knowledge visualization method according to an embodiment of the present invention.

Referring to FIG. 10, in step S910, the tile-based knowledge visualization apparatus constitutes a lattice space for arranging tiles, which is a basic unit of visualization. Here, the lattice space is a virtual space of a two-dimensional plane having rows and columns, and the lattice space is formed of a space in units of cells divided through horizontal and vertical dividing lines arranged at regular intervals in a two-dimensional plane space. According to one embodiment, only one tile can be placed in one cell. In addition, one of the rows and columns constituting the lattice space is marked with a classification criterion for the placement of tiles. For example, the classification criteria may be displayed in the first row and the first column.

At S920, the tile-based knowledge visualization device sets reference information to be placed in the rows and columns of the grid space to determine where the tiles will be placed. According to an embodiment of the present invention, the reference information has two formats, one of which is a reference information that can be classified, such as a format of a file or category information based on a classifiable domain. The other is an indexable sorting reference, in which sortable reference information such as an index number, a date, a version, and the like is arranged. Here, the user inputs and receives the reference information, or sets the reference information as previously stored basic reference information.

In S930, the tile-based knowledge visualization apparatus selects a start tile to be output first in the lattice space through user interaction when the lattice space is constructed. The start tile is the starting, or tile, starting point of visualization.

In S940, when the start tile is determined, the tile-based knowledge visualization apparatus outputs the grid space in which the start tile is arranged on the screen.

In step S950, if the user tiles to be output to the lower level through the interaction with the start tile, or if the user changes the screen configuration currently being output by adding the new reference information, the changed tiles and the grid space information are reflected, Update.

That is, as the user interaction is input in S950, the tile-based knowledge visualization apparatus analyzes the interaction signal in S960. The interaction according to the present invention may include a tile-based interface screen setting request, a tile level change request, a tile selection / non-selection request, a tile link content information output request, a tile-related lower layer tile output request,

In S970, the tile-based-type visualization apparatus changes the screen configuration according to the interaction analysis. For example, the tiles arranged in the lattice space and the lattice space can be enlarged or reduced in size according to the user's interaction. In addition, rows and columns of lattice space can be inserted, deleted, merged, and partitioned. Also, the output information of the tile has a level or a depth. That is, the amount of information output to the tile can be adjusted according to the output level given to the tile. These user interactions are described in detail in Figs. 4 to 8B below.

As the screen configuration is changed in step S980, the tile-based knowledge visualization apparatus outputs the changed tiles and the grid space on the screen in step S990.

At S1000, it is determined whether the user requests additional search. If it is determined in step S1000 that an additional search is requested, the tile-based knowledge visualization apparatus proceeds to step S950. On the other hand, if no further traversal is requested, the tile-based knowledge visualization device ends.
