Description
Technical Field
The embodiment of the invention relates to the technical field of computers, in particular to a method and a device for visualizing a reference relationship of a digital object identifier.
Background
The Digital Object Identifier (DOI) is a "Digital Identifier of an Object", has the characteristics of uniqueness and persistence, and becomes a general framework for managing network Digital content and identification. A user submits metadata for a digital object, registers with a DOI system, which is permanently assigned to a digital object and provides resolvable persistent network links for current information of the object, including the location and materials of the digital object on the Internet, etc. Although the information of a digital object may change continuously, its DOI number remains unchanged. A DOI number may be resolved in a DOI system into one or more values associated with the digital object identified by the DOI number, such as: URL, email address, other identifier and descriptive metadata. DOI is now widely used in literature such as periodicals, papers, scientific data, digital publications, and the like.
The registration and analytic query process of the general DOI registration system is as follows:
(1) user submission of registration metadata
When a user registers a DOI, the metadata of the document must be submitted. The composition of metadata is exemplified by journal articles: metadata includes elements such as publication name, issue number, title, abstract, publication date, author, citation DOI, and article DOI number.
(2) The registry system performs rule check and storage on the metadata
After receiving DOI metadata submitted by a user, the registration system performs rule verification of the metadata according to business rules, provides out-of-compliance data, and then stores the data in a system database
(3) Registration system for externally providing DOI analysis service
And after finishing the metadata storage, the registration system extracts the DOI registered in the metadata, sends the DOI related data to a Handle Server component and provides analysis service for the outside.
(4) DOI parsing queries
And the user queries the DOI in a way of a Handle protocol or a Handle proxy server. And the DOI registration system analyzes the DOI and returns the metadata corresponding to the DOI.
The multi-node introduction and introduction relation exists among documents, and the current system technology can inquire the single introduction and introduction relation condition through one DOI. But the complex reference relation situation cannot be intuitively shown, and the reader cannot be provided with global knowledge, such as: document a cites document B and document C; document B also cites document C. The citation relationship between document B and document C cannot be seen from the perspective of document a.
Because the digital object query result is a metadata file, and the applied DOI is obtained from the metadata, the applied DOI metadata needs to be queried again when the applied DOI information is required to be checked, and the overall appearance of the application relation is difficult to be seen clearly at a glance.
Since the document itself can register a DOI, its content can also be registered as a DOI alone, for example: a journal article has a DOI, and paragraphs of the article can also independently generate a paragraph DOI. Other documents can cite not only an article as DOI, but also can directly cite the paragraph DOI by skipping the article. The system now lacks a structural presentation view that fully presents such DOI reference relationships.
The citation and citation of documents is a correlation, and documents DOIs may cite other DOIs that also require the ability to display the cited DOIs, and such cited display views are lacking at present.

Fig. 1 is a schematic flowchart of a method for visualizing a reference relationship of a digital object identifier according to an embodiment of the present invention, as shown in fig. 1, the method includes:
step 101: acquiring a digital object identifier DOI (data object identifier) to be inquired and a reference relation level corresponding to an object to be inquired, which are input by a user;
specifically, a user inputs DOI numbers and reference relationship hierarchies of objects to be queried at a user terminal, wherein one object to be queried and the DOI numbers correspond to each other one by one, in addition, the objects to be queried can be used for guiding other objects, and the guided objects can be used for guiding, so that a multi-level reference relationship is formed, and the user can set the reference relationship hierarchies according to own requirements. The device acquires the DOI number and the reference relation level corresponding to the object to be queried, which are input by a user.
Step 102: acquiring corresponding DOI node data and a first relation node having an affiliation with the DOI number to be inquired from a data graph model according to the DOI number to be inquired, and acquiring a second relation node having a reference relation with the DOI number to be inquired of a corresponding level from the data graph model according to the reference relation level;
specifically, a pre-constructed data graph model is obtained, the data graph model comprises a plurality of DOI nodes and the subordinate relation or the reference relation among the DOI nodes, the device obtains corresponding DOI node data and first relation nodes with the subordinate relation with the DOI number to be inquired from the data graph model according to the obtained DOI number to be inquired, and obtains corresponding levels of second relation nodes with the reference relation with the DOI number to be inquired from the data graph model according to the reference relation level. It should be noted that the dependency relationship is a parent-child relationship identifier of the DOI node to be queried, the reference relationship is a reference relationship between the DOI node to be queried and other DOI nodes, and the reference relationship includes an indexing relationship and a quoted relationship.
Step 103: and sending the graph constructed by the DOI node data, the first relation node, the second relation node, the subordinate relation and the reference relation to a user terminal as a query result.
Specifically, because the data graph model includes the dependency relationship or the reference relationship among the nodes, after the first relationship node and the second relationship node corresponding to the DOI node to be queried are obtained, the DOI node data, the first relationship node, the second relationship node, the dependency relationship and the reference relationship can construct a graph of the relationship among the nodes, the graph is used as a query result, and the query result is sent to the user terminal. It should be noted that the DOI node data includes DOI nodes and attribute data of an object to be queried, the DOI nodes, the first relationship nodes and the second relationship nodes are represented by circles in the graph, a directional arrow is arranged between the DOI nodes and the first relationship nodes, the directional arrow indicates an affiliation, a directional arrow is arranged between the DOI nodes and the second relationship nodes, and the directional arrow indicates a reference relationship.
For example: fig. 2 is a schematic flow chart of a method for visualizing a reference relationship of a digital object identifier according to an embodiment of the present invention, as shown in fig. 2, including:
the device obtains a DOI number to be inquired and a reference relation level corresponding to an object to be inquired, wherein the DOI number to be inquired is the DOI number of an article 3, the reference relation level is 1, the device obtains DOI nodes corresponding to the article 3 and attribute data of the article 3 from a data graph model according to the DOI number to be inquired, and the attribute data comprise: it can be understood that the attribute data may also include other attribute information of the article 3, which is not specifically limited in this embodiment of the present invention, and the DOI node corresponding to the article 3 and the attribute data of the article 3 constitute DOI node data. First relationship nodes having an affiliation with the article 3 can also be obtained from the data graph model, as can be seen from fig. 2, the first relationship nodes include a term 1 node, a publication a node and a publisher node, and each first relationship node is indicated by a directional arrow with a corresponding DOI node of the article 3, and an association relationship is marked on the directional arrow. And acquiring second relation nodes of the first-level reference relation according to the reference relation hierarchy set by the user, wherein the second relation nodes comprise article 1 nodes, article 2 nodes, article A nodes and paragraph nodes, each second relation node and the DOI node corresponding to the article 3 are indicated by a directional arrow, and the association relation is marked on the directional arrow. Since the user specifies that the reference relationship hierarchy is 1, the second relationship node does not include the article 1 node, the article 2 node, the article a node, and the next-level reference relationship after the paragraph node. It should be noted that the dependency relationship between the first relationship node and the second relationship node may also be noted.
According to the embodiment of the invention, the DOI node data and the first relation node having the dependency relationship with the DOI number to be inquired are obtained from the data graph model according to the DOI number to be inquired, the second relation node is obtained according to the reference relationship level, and finally the constructed graph is used as the query result and is sent to the user terminal, so that the user can visually obtain the reference relationship among all the nodes.

and establishing association relations between the DOI nodes and the first relation nodes respectively according to the subordination relations, and establishing association relations between the DOI nodes and the second relation nodes according to the reference relations so as to construct the data graph model.
Specifically, a data graph model is constructed in advance, the data graph model comprises a plurality of objects, each object has corresponding DOI metadata, and the DOI metadata comprises a DOI number, attribute data, a first relation node with an affiliation relation with the DOI number and a second relation node with a reference relation with the DOI number. And finally, establishing an association relationship between the DOI number and the first relationship node according to the dependency relationship, and establishing an association relationship between the DOI number and the second relationship node according to the reference relationship. And constructing each object in the data graph model by using the method, and finally obtaining the complete data graph model. It should be noted that after creation is complete, the data diagram model is stored in the database. Fig. 3 is a schematic diagram of a node and a reference relationship of DOI data of periodicals provided in an embodiment of the present invention, where as shown in fig. 3, an object a is a node to be inserted into a data model, DOI metadata corresponding to an article a includes a DOI number a, attribute data is not shown in the diagram, a type X of the publication having an affiliation with the article a, an article B having a reference relationship with the article a, a node of the type X of the publication and the type X of the publication is created, then an affiliation is established between the article a and the type X of the publication, and an indexing relationship is established between the article a and the article.
According to the embodiment of the invention, the data graph model is created in advance, so that when a user inquires an object, the nodes related to the object can be displayed in a graph form, and the user can conveniently know the object.
On the basis of the above embodiment, the establishing a DOI node according to the DOI number, and storing the DOI number and corresponding attribute data into the DOI node includes:
judging whether the DOI exists in the data graph model or not, if not, establishing a DOI node according to the DOI, and storing the DOI and corresponding attribute data into the DOI node;
specifically, when creating a DOI node for an object, first, it may be queried in the data graph model whether a DOI number of the object already exists, if not, the DOI node may be created according to the DOI number, and the DOI number and attribute data in metadata of the object are stored in the DOI node to form DOI node data.
Accordingly, the method can be used for solving the problems that,
the establishing of the association relationship between the DOI nodes and the first relationship nodes respectively according to the subordination relationship and the establishing of the association relationship between the DOI nodes and the second relationship nodes according to the reference relationship to establish and complete the data graph model comprises the following steps:
if the data graph model is judged to have no first relation node with the dependency relationship with the DOI metadata, establishing a corresponding first relation node, and establishing an incidence relationship between the DOI node and the first relation node;
and if the data graph model is judged to have no second relation node having a reference relation with the DOI metadata, establishing a corresponding second relation node, and establishing an association relation between the DOI node and the second relation node.
Specifically, after the DOI node data is created, whether a first relation node having an affiliation with the object exists is searched from the data graph model, if not, a first relation node is automatically created, and then the association relationship between the DOI node and the first relation node is established, that is, the DOI node and the first relation node are connected by a directed arrow and marked as an affiliation.
If the DOI node has a second relation node of the reference relation and the data graph model does not have the second relation node, automatically creating a second relation node, and then establishing the association relation between the DOI node and the second relation node, namely connecting the DOI node and the second relation node by using a directed arrow and marking the DOI node and the second relation node as the reference relation.
It should be noted that after the data graph model is built, the data graph model may be mined, that is, if a node is clicked in the data graph model interface, the relationship node and the related attribute data are displayed, and if the relationship node is further clicked, the relationship of the relationship node may be mined, and the next-level node is further displayed.

and judging whether the DOI exists in the data graph model or not, and if so, updating attribute data corresponding to the DOI in the data graph model, a first relation node with an affiliation and a second relation node with a reference relation.
Specifically, because the DOI metadata of the object may change, after the DOI metadata of the object required for constructing the data graph model is obtained, the DOI number is obtained from the DOI metadata, whether the DOI number already exists in the data graph model is determined, and if the DOI number already exists, it is indicated that data in the data graph model needs to be updated, at this time, all attribute data in the DOI node in the data graph model, the first relationship node having the dependency relationship, and the second relationship node having the reference relationship are deleted, and then information in the newly obtained DOI metadata of the object is reconstructed.
According to the embodiment of the invention, the information of the node is updated by judging the DOI node in the data graph model, so that a user can obtain a more accurate result during query.
On the basis of the above embodiment, the obtaining, from the data graph model according to the reference relationship hierarchy, the second relationship node having a reference relationship with the object to be queried at a corresponding hierarchy includes:
and recursively acquiring second relation nodes having reference relations with the DOI to be inquired, and stopping the recursion to acquire the second relation nodes of corresponding hierarchies if the number of recursions is judged to be equal to the reference relation hierarchy.
Specifically, when the corresponding second relationship node is obtained from the data graph model according to the DOI number to be queried, the node is obtained in a recursive mining mode, namely, a first layer of DOI nodes having a direct reference relationship with the DOI number to be queried is obtained first, and after the first layer of DOI nodes is obtained, a second layer of DOI nodes is obtained, and the number of obtained layers is known to reach a reference relationship level set by a user. For example: and if the reference relation level set by the user is 2, the query result obtained after the query is the atlas of the DOI node to be queried, the DOI node A and the DOI node B.
The embodiment of the invention acquires the query result of the corresponding level from the data graph model in a recursive mode, and can accurately return the query result to the user terminal.
On the basis of the above embodiment, the method further includes:
acquiring object metadata of an object to be registered submitted by a user, registering according to the object metadata, and generating a DOI (disk over interface) number corresponding to the object to be registered.
Specifically, the device obtains object metadata of an object to be registered submitted by a user, for example: to register a corresponding DOI number for an article, the submitted object metadata may include: article name, author, date, keyword, etc., and the device generates only one DOI number according to the object metadata and then returns the generated DOI number to the user terminal.
According to the embodiment of the invention, the DOI node data and the first relation node having the dependency relationship with the DOI number to be inquired are obtained from the data graph model according to the DOI number to be inquired, the second relation node is obtained according to the reference relationship level, and finally the constructed graph is used as the query result and is sent to the user terminal, so that the user can visually obtain the reference relationship among all the nodes.
