Detailed Description
In order to more clearly illustrate the invention, the invention is further described below with reference to preferred embodiments and the accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.
One embodiment of the present invention provides a knowledge graph-based visualization display method, which implements a hardware architecture as shown in fig. 1, that is, the method can be implemented in a client-server manner, that is, a software client is installed on a PC end such as a desktop or a mobile terminal such as a mobile phone or a tablet computer, and a knowledge graph database such as Neo4j is stored in a cloud server. The method of the invention is implemented when the software APP is run.
It will be appreciated by those skilled in the art that the implementation of the method of the present invention is not limited to the above-described hardware architecture, and the knowledge graph database may also be stored in a memory of, for example, a mobile terminal.
The knowledge graph-based visualization display method disclosed by the invention, as shown in figure 2, comprises the following steps of:
and S10, presenting the time axis and the world map on the visual interface.
In one example, when the user opens the client, the software presents a top page interface as shown in FIG. 3, with a world map in the middle of the page and a timeline in the bottom. The timeline in the figure is presented in a way that the time from the left end to the right end is closer and closer to modern times, and in the interface illustrated in fig. 3, a clip from the year 700 to the year 730 of the axia is displayed, however, as can be appreciated by those skilled in the art, the total length of the timeline depends on the time range of acquisition in the knowledge graph.
S12, responding to the trigger of the user to the time point on the time axis, presenting the identification of the historical celebrity from the knowledge-graph existing at the time point on the world map, wherein the identification of the historical celebrity is presented at the geographic position related to the historical celebrity.
In one specific example, as a user clicks a point on a time axis with a pointing device such as a mouse to adaptively screen display a time range centered on the clicked point, as shown in fig. 3, the point on the click time axis is a axiom 715 years, the left end of the displayed range is an axiom 700 years, and the right end is an axiom 730 years. When the user clicks on the point in time, the world map then presents an identification, e.g., an avatar, of the celebrity present in the world at the point in time, and the avatar is presented at a geographic location corresponding to the celebrity's nationality. In another specific example, the avatar is presented at a geographic location corresponding to the celebrity's place of birth. In yet another specific example, the avatar is presented at a frequently active corresponding geographic location of the celebrity.
In practice, when a user clicks on a point in time on the timeline, the software client sends a query request to the knowledge-graph database, and the query results are returned by the knowledge-graph database and presented at the corresponding geographic location of the world map.
In the above example, the minimum resolution at the time point on the time axis is year. However, the invention is not so limited and relies on information collection and knowledge cleansing of the respective knowledge-graphs.
When the nationality of the celebrity is recorded in the knowledge graph, the query result preferentially returned by the knowledge graph database is the geographic position corresponding to the nationality of the celebrity. If the nationality information does not exist and the place of birth information exists, the inquiry result returned by the knowledge map database is the geographic position corresponding to the place of birth of the celebrity. If neither of the two is available, the query result returned by the knowledge graph database is the corresponding geographical position of the celebrity with frequent activities.
The construction of various information in the artistic knowledge map will be described later.
The celebrities are, for example, artists with historically known names such as painters, engravers, music operas, and possibly other political history figures of which emperors will be equal, depending on what the constructed knowledge graph is.
Next, the present invention is explained by taking the knowledge map as an example of an artistic knowledge map. In this case, fig. 3 presents the identification of 3 artists on the world map at the time point of the year 715 in the notary, since artist 1, artist 2 and artist 3, and are presented at the corresponding geographical locations according to their three-person nationality, respectively.
In another specific example, with a time tab on the time axis, the user can drag the time tab to stop to a desired point in time.
In the example with time tags on the time axis, the method of the present invention preferably further comprises
In response to the user dragging the time tag, presentation of the identity of the historical celebrity is commenced at the geographic location to which the world map is associated when the point in time of arrival corresponds to the birth time of the historical celebrity until the identity of the historical celebrity disappears when the point in time of arrival exceeds the death time of the historical celebrity.
In this way, the user is enabled to more intuitively see the time of the historical character in the world.
In the example of a historical celebrity artist, while presenting an identification of an artist present at the point in time on the world map, the method of the present invention further comprises:
and S14, presenting the artistic genre or the era corresponding to the period to which the time point belongs on the visual interface.
For example, for painting, it is divided by genre in the west, as shown in fig. 8, for example, in the year 715 of a notary, and belongs to the byzantine art. In china, there is no clear genre division, but the genres are divided into generations, and the period of the era 715 corresponds to the down generation. Thus, in fig. 3, byzantine art and down-typos are presented below point in time 715.
When there is no corresponding chinese painter but only western painters at this point in time, only genres are presented. Instead, only dynasty is presented.
Through such a presentation form, the user can more intuitively understand the genre to which the artist appearing at the time point belongs or the era to which the artist belongs.
Next, the method of the present invention may further include:
and S16, responding to the click of the user on the historical celebrity identification, and presenting the information of the historical celebrity corresponding to the clicked identification.
In the example where the knowledge graph is an art knowledge graph, as shown in FIG. 4, an encyclopedia card, a relationship graph, and three tabs representing a work are presented. In the specific example shown in fig. 4, the user clicks on the artist identification of the top page, and the information for that artist is presented in the form of an encyclopedia card by default, for example:
the foreign language name: XXX by alias: XXX nationality: XXX dried rehmannia root: XXX
Birth year: XXX death year: genre XXX: XXX represents as follows: XXX
Brief introduction:
XXX XXXXXXXXX
the user may also click on the relationship graph tab and jump to the interface shown in fig. 5. And displaying the relation map of the artist in a scattering state by taking the artist as a center on an interface. Including their teachers and apprentices, artists in the same genre as they belong to, artists in the same nationality as they belong to, etc.
The user may also click on the tab representing the work and jump to the interface shown in FIG. 6. On this interface, the works of the artist are presented in thumbnail form. Shown as 6, the user may also click on the page turn left and right buttons (not shown) to turn the page if the artist has more works.
Further, in response to a user manipulation (e.g., clicking) on a thumbnail, the artwork corresponding to the thumbnail is presented (in the case of copyright permission).
Although the above example shows the artist information first in the form of an encyclopedia card by default in the event that the user clicks the home page identification, those skilled in the art will appreciate that the present invention is not so limited and that a relationship chart page or a representative work page may also be displayed first, on such a page there are still two more tabs for the user to select.
Further, in the above example of an artist, if the historical celebrity is a historical political figure, the historical political figure does not represent a work, in this case, there may be only two display forms of an encyclopedia card and a relationship map, and of course, those skilled in the art can understand that there may be other tabs corresponding to the historical political figure, and the present invention is not limited thereto.
In an alternative example, in addition to the timeline-map visualization presentation described above, a search box is also presented on the visualization interface presented in fig. 2 for the user to enter search terms. The search box is often suitable for scenarios where the user is problem-specific, such as where it is desirable to know the year of birth of Picasso.
To assist user input, the software presents a search paradigm in the form of a drop-down menu when the user clicks in the search box, for example:
picasso
Birth year of Picasso
Picasso works
The school of Picasso
The relationship between the teacher and the bearing of the painter in the period of recovering the characters and crafts.
In a specific example, the software detects that the user has only entered the name of the artist, and after the user has entered the artist or clicked the "search" key (not shown) next to the search box, the software can analyze based on semantic analysis that the user has entered something other than a definite question, so the software is configured to jump to the interface shown in fig. 4, i.e., the information interface presented by the encyclopedia tab, because the encyclopedia is more dimensional in information presented in the form of a nationality, place of birth, work, genre, brief introduction, etc.
Further, the named entity recognition of the information entered by the user can be performed using conditional random fields.
In another specific example, when the software detects that the user has entered a sentence with definite directional question such as "begonia year of birth", "begonia work", "begonia genre", after the user has entered a carriage return or clicked the "search" key next to the search box, the software jumps to a new interface, presenting only answers, for example: in 1881.
Preferably, when the software detects that the user inputs a relational question such as "teacher-bearing relation of artist in time of renaming", the software jumps to the relational map interface shown in fig. 5 after the user enters a car or clicks the "search" key next to the search box.
Preferably, when the software detects that the user inputs, for example, "Picasso works", after the user returns or clicks the "search" key next to the search box, the software preferably jumps to the interface representing works shown in FIG. 6, which is more vivid in the form of thumbnails than the above text answers, thereby enhancing the user experience.
As mentioned above, the implementation of the above visualization presentation manner is technically a means of initiating a request from the visualization interface, searching answers from the knowledge graph database, and returning the answers to the visualization interface for presentation. This requires the establishment of a prior knowledge profile database. Next, the knowledge-graph database building method of the present invention is given by way of an artistic knowledge-graph example.
Entity-relationship construction
As shown in fig. 7, the art knowledge related to the artist in the art knowledge graph includes influence, teachers and apprentices (which may be stored and displayed through a relationship graph), death time (in terms of a unit of.
Knowledge cleaning
Due to the fact that the Chinese and foreign era ways are different, time expression ways in the collected information during the construction of the knowledge graph are various, so that the time expression ways are various, and the display difficulty is caused. Therefore, the time standardization is carried out, and the display of related data is facilitated.
In one particular example, the method of the present invention focuses primarily on four time dimensions: artist-year of birth, artist-year of death, genre time, era. The birth year and the death year belong to time points and are uniformly represented numerically; genre time and era belong to a time period, converted into a numerical value. As shown in fig. 8, the non-normalized data is converted into corresponding normalized time data.
Knowledge generation
In a specific example, as shown in fig. 9, the data in the art knowledge graph is structured data, and when the art knowledge graph is queried, the entities and the relationships in the data can be extracted according to the "entity-relationship table" (similar to a large excel table) in the above entity-relationship construction. The extracted value is (entity 1value, entity 2value, relationship) shape, and then it is determined whether the entity 2 data is multivalued, for example, the extracted entity 1 data is bysuger and the entity 2 data is a work, in which case the entity 2 data is multivalued (there are a plurality of works), and a plurality of relationships, that is, (entity 1value, entity 2value1, relationship) (entity 1value, entity 2value2, relationship), etc. are generated. Otherwise, a relationship is generated, i.e., (entity 1value, entity 2value, relationship).
Knowledge storage
The artistic knowledge map is stored in a map database (e.g., Neo4j), and may be linked by a URL address using cloud storage, i.e., the cloud server mentioned above. Or may be stored in the local machine.
As mentioned above, the method of the present invention can be implemented on a terminal device, for example, installed on the terminal device in the form of a software application, and the terminal device can be various electronic devices, including but not limited to a personal computer, a smart phone, a tablet computer, a personal digital assistant, and the like.
In an example where the knowledge graph database is provided in a cloud server, the server may be a server providing various services, and the server may perform processing such as storage, analysis, and the like on received data (a user query sent by a terminal device), and feed back a processing result to the terminal device, and the processing result is output to a user by the terminal device through an interaction module such as a touch screen. The terminal devices and the server communicate over a network, which may include various connection types, such as wired, wireless communication links, or fiber optic cables, among others.
In the embodiments of the present disclosure, the specific implementation of the so-called "receiving" corresponds to the way in which the user uses the terminal device. For example, when a user inputs data into a personal computer by using a keyboard, the personal computer receives the data input by the user; for example, a user inputs data by mouse clicking, keyboard operation, or the like on an application GUI interface of a personal computer that executes an art information presentation method, and the personal computer captures the operations to receive the data input by the user; for example, if the user inputs data in a voice mode, the personal computer receives the data input by the user through a method of converting voice into text; for example, if the user uses a mobile phone App, the server may receive data input by the user through interaction with the mobile phone used by the user.
Fig. 10 shows one specific example of a terminal device, including a central processing module (CPU), which can perform various appropriate actions and processes according to a program stored in a Read Only Memory (ROM) or a program loaded from a storage section into a Random Access Memory (RAM). In the RAM, various programs and data necessary for the operation of the computer system are also stored. The CPU, ROM, and RAM are connected thereto via a bus. An input/output (I/O) interface is also connected to the bus.
An input section including a keyboard, a mouse, and the like; an output section including a speaker and the like such as a Liquid Crystal Display (LCD); a storage section including a hard disk and the like; and a communication section including a network interface card such as a LAN card, a modem, or the like. The communication section performs communication processing via a network such as the internet. The drive is also connected to the I/O interface as needed. A removable medium such as a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, or the like is mounted on the drive as necessary, so that a computer program read out therefrom is mounted into the storage section as necessary.
In particular, the processes described in the above flowcharts may be implemented as computer software programs according to the present embodiment. For example, the present embodiments include a computer program product comprising a computer program tangibly embodied on a computer-readable medium, the computer program comprising program code for performing the method illustrated in the flow chart. In such an embodiment, the computer program may be downloaded and installed from a network via the communication section, and/or installed from a removable medium.
