技术领域technical field
本发明实施例涉及计算机技术领域，尤其涉及一种数字对象标识符引用关系的可视化方法及装置。The embodiments of the present invention relate to the field of computer technology, and in particular, to a method and device for visualizing the reference relationship of digital object identifiers.
背景技术Background technique
数字对象标识符(Digital Object Identifier，简称DOI)即为“一个对象的数字标识符”，它具有唯一性、持久性的特点，成为管理网络数字内容及识别的通用框架。用户提交数字对象的元数据，向DOI系统进行注册，DOI被永久性地分配给一个数字对象，并为该对象的当前信息提供可解析的持久性网络链接，这些当前信息包括该数字对象在互联网上的位置和资料等。尽管一个数字对象的信息可以不断改变，但其DOI号保持不变。一个DOI号可在DOI系统中解析为一种或多种与该DOI号所标识的数字对象相关的值，例如：URL、电子邮箱地址、其他标识符和描述性元数据。DOI现在已经广泛应用在期刊、论文、科学数据、数字出版物等文献方面。Digital Object Identifier (Digital Object Identifier, referred to as DOI) is the "digital identifier of an object", which has the characteristics of uniqueness and persistence, and has become a general framework for managing network digital content and identification. The user submits the metadata of the digital object, registers with the DOI system, the DOI is permanently assigned to a digital object, and provides a resolvable persistent network link for the object's current information, including the digital object on the Internet. location and information etc. Although a digital object's information can change continuously, its DOI name remains the same. A DOI name resolves within the DOI system to one or more values associated with the digital object identified by the DOI name, such as URLs, email addresses, other identifiers, and descriptive metadata. DOI has now been widely used in journals, papers, scientific data, digital publications and other documents.
一般DOI注册系统的注册和解析查询流程如下：The registration and resolution query process of the general DOI registration system is as follows:
(1)用户提交注册元数据(1) User submits registration metadata
用户注册DOI时候，必须提交文献的元数据。元数据的组成以期刊文章为例：元数据包括刊物名称、期号、标题、摘要、出版日期、作者、施引文献DOI以及文章DOI号等元素。When users register for DOI, they must submit the metadata of documents. The composition of metadata takes journal articles as an example: metadata includes journal name, issue number, title, abstract, publication date, author, citing document DOI, article DOI number and other elements.
(2)注册系统对元数据进行规则校验和存储(2) The registration system checks and stores the metadata according to the rules
注册系统在接到用户提交的DOI元数据后，按照业务规则进行元数据的规则校验，提出不合规的数据，然后将数据存储到系统数据库中After receiving the DOI metadata submitted by the user, the registration system checks the metadata according to the business rules, proposes non-compliant data, and then stores the data in the system database
(3)注册系统对外提供DOI解析服务(3) The registration system provides external DOI analysis services
注册系统在完成元数据存储后，将元数据中注册的DOI进行提取操作，将DOI相关数据，发送给Handle Server部件，对外提供解析服务。After the registration system completes the metadata storage, it extracts the DOI registered in the metadata, sends the DOI related data to the Handle Server component, and provides external analysis services.
(4)DOI解析查询(4) DOI analysis query
用户通过Handle协议或者handle代理服务器的方式，查询DOI。DOI注册系统进行DOI解析，并返回DOI对应的元数据。Users query the DOI through the Handle protocol or the handle proxy server. The DOI registration system analyzes the DOI and returns the metadata corresponding to the DOI.
文献之间存在多节点的施引和被引关系，当前的系统技术上实现通过一个DOI，可以查询到单一的施引和被引的关系情况。但无法直观展示复杂的引用关系情况，无法给读者提供全局的认识，例如：文献A引用了文献B和文献C；文献B也引用文献C。在文献A的角度无法看到文献B和文献C存在引用关系。There are multi-node citing and cited relationships between documents. The current system technology realizes that through a DOI, a single citing and cited relationship can be queried. However, it is impossible to visually display complex citation relationships and provide readers with an overall understanding. For example, document A cites document B and document C; document B also cites document C. From the perspective of document A, it is impossible to see that there is a citation relationship between document B and document C.
由于数字对象查询结果是元数据文件，再从元数据中获取施引的DOI，想要查看施引DOI信息，必须再次查询施引DOI元数据，很难一目了然看清施引关系全貌。Since the digital object query result is a metadata file, and then the citing DOI is obtained from the metadata, if you want to view the citing DOI information, you must query the citing DOI metadata again, and it is difficult to see the whole picture of the citing relationship at a glance.
由于文献本身可以注册一个DOI，其内容也能够单独注册为一个DOI，例如：某期刊文章有一个DOI，文章的段落也能单独生成一个段落DOI。其他文献能施引的不仅文章是DOI，而且能够跳过文章直接施引段落DOI。现在系统缺少全面展示这种DOI引用关系的结构展示视图。Since the document itself can be registered as a DOI, its content can also be registered as a separate DOI. For example, a journal article has a DOI, and the paragraphs of the article can also generate a paragraph DOI separately. Other documents can not only cite the DOI of the article, but also skip the article and directly cite the DOI of the paragraph. Currently, the system lacks a structural display view to comprehensively display the DOI citation relationship.
文献施引和被引是一种相互关系，文献DOI可以施引其他DOI，其他DOI也需要能够展示被引DOI的情况，目前这种被引的展示视图也是缺乏的。Document citing and being cited are a mutual relationship. A document DOI can cite other DOIs, and other DOIs also need to be able to display the situation of the cited DOI. At present, there is a lack of such a citation display view.

具体实施方式Detailed ways
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
图1为本发明实施例提供的一种数字对象标识符引用关系的可视化方法流程示意图，如图1所示，所述方法，包括：Fig. 1 is a schematic flowchart of a method for visualizing the reference relationship of digital object identifiers provided by an embodiment of the present invention. As shown in Fig. 1, the method includes:
步骤101：获取用户输入的待查询对象对应的待查询数字对象标识符DOI号及引用关系层级；Step 101: Obtain the digital object identifier DOI number and reference relationship level corresponding to the object to be queried input by the user;
具体的，用户在用户终端输入待查询对象的DOI号和引用关系层级，其中，一个待查询对象和DOI号是一一对应的，另外，待查询对象可以施引其他的对象，被引的对象还可以进行施引，这样就构成了多层级的引用关系，用户可以根据自己的需求设定引用关系层级。装置获取用户输入的待查询对象对应的DOI号及引用关系层级。Specifically, the user enters the DOI number and the reference relationship level of the object to be queried on the user terminal, where an object to be queried is in one-to-one correspondence with the DOI number. In addition, the object to be queried can refer to other objects, and the cited object Citation can also be performed, thus forming a multi-level citation relationship, and users can set the citation relationship level according to their own needs. The device acquires the DOI number and reference relationship level corresponding to the object to be queried input by the user.
步骤102：根据所述待查询DOI号从数据图模型中获取对应的DOI节点数据及与所述待查询DOI号具有从属关系的第一关系节点，根据所述引用关系层级从数据图模型中获取对应层级的与所述待查询DOI号有引用关系的第二关系节点；Step 102: Obtain the corresponding DOI node data from the data graph model according to the DOI name to be queried and the first relationship node having an affiliation relationship with the DOI number to be queried, and obtain it from the data graph model according to the reference relationship level A second relationship node that has a reference relationship with the DOI number to be queried at the corresponding level;
具体的，获取预先构建的数据图模型，数据图模型中包括了多个DOI节点，以及各个DOI节点之间的从属关系或引用关系，装置根据获取到的待查询DOI号从数据图模型中获取对应的DOI节点数据以及与待查询DOI号具有从属关系的第一关系节点，并且，根据引用关系层级从数据图模型中获取相应层级的与待查询DOI号具有引用关系的第二关系节点。其中，应当说明的是，从属关系是该待查询DOI节点父子关系标识，引用关系是待查询DOI节点与其他DOI节点之间的引用关系，引用关系包括施引关系和被引关系。Specifically, the pre-built data graph model is obtained, and the data graph model includes a plurality of DOI nodes, and the affiliation or reference relationship between each DOI node, and the device obtains from the data graph model according to the acquired DOI number to be queried. The corresponding DOI node data and the first relationship node having a subordinate relationship with the DOI number to be queried, and obtaining the second relationship node having a reference relationship with the DOI number to be queried at the corresponding level from the data graph model according to the reference relationship level. Wherein, it should be noted that the affiliation relationship is the identification of the parent-child relationship of the DOI node to be queried, and the citation relationship is the citation relationship between the DOI node to be queried and other DOI nodes, and the citation relationship includes a citing relationship and a cited relationship.
步骤103：将所述DOI节点数据、所述第一关系节点、所述第二关系节点、所述从属关系和所述引用关系构建的图谱作为查询结果发送至用户终端。Step 103: Send the graph constructed by the DOI node data, the first relationship node, the second relationship node, the affiliation relationship and the reference relationship to the user terminal as a query result.
具体的，由于数据图模型中包括了各个节点之间的从属关系或引用关系，因此，在获取到待查询DOI节点对应的第一关系节点和第二关系节点后，DOI节点数据、第一关系节点、第二关系节点、从属关系和引用关系可以构建出各个节点之间关系的图谱，将该图谱作为查询结果，将查询结果发送至用户终端。应当说明的是，DOI节点数据中包括DOI节点以及待查询对象的属性数据，DOI节点、第一关系节点和第二关系节点在图谱中用圆圈表示，DOI节点与第一关系节点之间有指向箭头，指向箭头上表明从属关系，DOI节点与第二关系节点之间有指向箭头，指向箭头上表明引用关系。Specifically, since the data graph model includes the affiliation or reference relationship between each node, after obtaining the first relationship node and the second relationship node corresponding to the DOI node to be queried, the DOI node data, the first relationship The node, the second relationship node, the affiliation relationship and the reference relationship can construct a map of the relationship between each node, use the map as a query result, and send the query result to the user terminal. It should be noted that the DOI node data includes the DOI node and the attribute data of the object to be queried. The DOI node, the first relationship node and the second relationship node are represented by circles in the map, and there is a pointing relationship between the DOI node and the first relationship node. Arrows, the pointing arrows indicate the affiliation relationship, and there are pointing arrows between the DOI node and the second relationship node, and the pointing arrows indicate the reference relationship.
例如：图2为本发明实施例提供的数字对象标识符引用关系的可视化方法流程示意图，如图2所示，包括：For example: Figure 2 is a schematic flowchart of a method for visualizing the reference relationship of digital object identifiers provided by the embodiment of the present invention, as shown in Figure 2, including:
装置获取用户输入的待查询对象对应的待查询DOI号及引用关系层级，其中，待查询DOI号为文章3的DOI号，引用关系层级为1，装置根据待查询DOI号从数据图模型中获取文章3对应的DOI节点和文章3的属性数据，其中属性数据包括：标题、作者和发表时间，可以理解的是，属性数据还可以有文章3的其他属性信息，本发明实施例对此不做具体限定，文章3对应的DOI节点和文章3的属性数据构成了DOI节点数据。从数据图模型中还可以获取到与文章3具有从属关系的第一关系节点，从图2中可以看出，第一关系节点包括期1节点、刊物A节点和某出版社节点，且每一第一关系节点与文章3对应的DOI节点之间用指向箭头指示，并且在指向箭头上标注关联关系。根据用户设置的引用关系层级可以获取到第一级引用关系的第二关系节点，其中，第二关系节点包括文章1节点、文章2节点、文章A节点和段落节点，且每一第二关系节点与文章3对应的DOI节点之间用指向箭头指示，并且在指向箭头上标注关联关系。由于用户指定引用关系层级为1，因此，第二关系节点中不包括文章1节点、文章2节点、文章A节点和段落节点之后的下一级引用关系。应当说明的是，还可以对第一关系节点和第二关系节点之间的从属关系进行标注。The device acquires the DOI number to be queried and the citation relationship level corresponding to the object to be queried input by the user, wherein the DOI number to be queried is the DOI number of article 3, and the citation relationship level is 1, and the device obtains it from the data graph model according to the DOI number to be queried The DOI node corresponding to article 3 and the attribute data of article 3, wherein the attribute data includes: title, author and publication time, it can be understood that the attribute data can also have other attribute information of article 3, which is not done in the embodiment of the present invention Specifically, the DOI node corresponding to the article 3 and the attribute data of the article 3 constitute the DOI node data. From the data graph model, we can also obtain the first relationship node that has a subordinate relationship with article 3. It can be seen from Figure 2 that the first relationship node includes the issue 1 node, publication A node and a publishing house node, and each A pointing arrow is used to indicate the relationship between the first relationship node and the DOI node corresponding to the article 3, and an association relationship is marked on the pointing arrow. According to the citation relationship level set by the user, the second relationship node of the first-level citation relationship can be obtained, wherein the second relationship node includes article 1 node, article 2 node, article A node and paragraph node, and each second relationship node The DOI nodes corresponding to Article 3 are indicated by pointing arrows, and the association relationship is marked on the pointing arrows. Since the citation relationship level specified by the user is 1, the second relationship node does not include the next-level citation relationship after the article 1 node, article 2 node, article A node, and paragraph node. It should be noted that the affiliation relationship between the first relationship node and the second relationship node may also be marked.
本发明实施例通过根据待查询DOI号从数据图模型中获取DOI节点数据及与待查询DOI号具有从属关系的第一关系节点，并根据引用关系层级获取第二关系节点，最后将构建的图谱作为查询结果发送至用户终端，使得用户能够直观的获取各个节点之间的引用关系。In the embodiment of the present invention, the DOI node data and the first relationship node having a subordinate relationship with the DOI number to be queried are obtained from the data graph model according to the DOI number to be queried, and the second relationship node is obtained according to the reference relationship level, and finally the constructed map It is sent to the user terminal as a query result, so that the user can intuitively obtain the reference relationship between each node.
在上述实施例的基础上，所述方法，还包括：On the basis of the foregoing embodiments, the method further includes:
获取构建所述数据图模型中对象对应的DOI元数据，所述DOI元数据包括DOI号、属性数据、与所述DOI号有从属关系的第一关系节点和与所述DOI号有引用关系的第二关系节点；Obtain the DOI metadata corresponding to the object in the data graph model, the DOI metadata includes the DOI number, attribute data, the first relationship node that has a subordinate relationship with the DOI number, and the reference relationship with the DOI number second relationship node;

具体的，预先构建数据图模型，数据图模型中包括了多个对象，每个对象都具备对应的DOI元数据，DOI元数据包括DOI号、属性数据、与DOI号有从属关系的第一关系节点和与DOI号有引用关系的第二关系节点。根据每一个对象的DOI号建立DOI节点，然后将DOI号和对应的属性数据存储到DOI节点中，构成DOI节点数据，在数据图模型中添加与DOI号有从属关系的第一关系节点和与DOI号有引用关系第二关系节点，最后根据从属关系建立DOI号与第一关系节点的关联关系，根据引用关系建立DOI节点与第二关系节点之间的关联关系。对于数据图模型中的每个对象均用上述方法进行构建，最终可以获得完整的数据图模型。应当说明的是，在创建完成后，将数据图模型存储到数据库中。图3为本发明实施例提供的期刊类DOI数据的节点与引用关系示意图，如图3所示，对象A为要插入到数据模型中的一个节点，文章A对应的DOI元数据包括DOI号为A，属性数据未在图中示出，与文章A有从属关系的刊类型X，与文章A有引用关系的文章B，创建刊类型X和文章B的节点，然后在文章A和刊类型X之间建立从属关系，在文章A和文章之间建立施引关系。Specifically, the data graph model is pre-built. The data graph model includes multiple objects, and each object has corresponding DOI metadata. The DOI metadata includes the DOI number, attribute data, and the first relationship with the DOI number. node and a second relationship node that has a reference relationship with the DOI name. Create a DOI node according to the DOI number of each object, then store the DOI number and the corresponding attribute data in the DOI node to form the DOI node data, and add the first relationship node with the subordinate relationship with the DOI number and the first relationship node with the DOI number in the data graph model The DOI name has a reference relationship to the second relationship node. Finally, the association relationship between the DOI name and the first relationship node is established according to the affiliation relationship, and the association relationship between the DOI node and the second relationship node is established according to the reference relationship. Each object in the data graph model is constructed by the above method, and finally a complete data graph model can be obtained. It should be noted that, after the creation is completed, the data graph model is stored in the database. Fig. 3 is a schematic diagram of the node and reference relationship of periodical DOI data provided by the embodiment of the present invention. As shown in Fig. 3, object A is a node to be inserted into the data model, and the DOI metadata corresponding to article A includes the DOI number as A, the attribute data is not shown in the figure, the journal type X that has a subordinate relationship with article A, and the article B that has a citation relationship with article A, create a node of journal type X and article B, and then create a node between article A and journal type X Establish an affiliation relationship between them, and establish a citing relationship between Article A and the article.
本发明实施例通过预先创建数据图模型，以使用户在查询某个对象时，可以将与该对象有关系的节点以图形的形式展示出来，便于用户对其进行了解。The embodiment of the present invention creates a data graph model in advance, so that when a user inquires about an object, the nodes related to the object can be displayed in the form of a graph, which is convenient for the user to understand.
在上述实施例的基础上，所述根据所述DOI号建立DOI节点，并将所述DOI号和对应的属性数据存储至所述DOI节点中，包括：On the basis of the above embodiments, the establishment of a DOI node according to the DOI number, and storing the DOI number and corresponding attribute data in the DOI node includes:
判断所述数据图模型中是否已存在所述DOI号，若不存在，则根据所述DOI号建立DOI节点，并将所述DOI号和对应的属性数据存储至所述DOI节点中；judging whether the DOI number already exists in the data graph model, if not, establishing a DOI node according to the DOI number, and storing the DOI number and corresponding attribute data into the DOI node;
具体的，在为对象创建DOI节点时，首先可以在数据图模型中查询是否已经存在该对象的DOI号，如果不存在，则可根据DOI号建立DOI节点，并且将该对象的元数据中的DOI号和属性数据存储至DOI节点中，以构成DOI节点数据。Specifically, when creating a DOI node for an object, you can first query whether the DOI number of the object already exists in the data graph model. If it does not exist, you can create a DOI node based on the DOI number, and use the DOI name and attribute data are stored in DOI nodes to form DOI node data.
相应的，corresponding,

若判断所述数据图模型中不存在与所述DOI元数据具有从属关系第一关系节点，则创建对应的第一关系节点，并建立DOI节点与第一关系节点之间的关联关系；If it is judged that there is no first relationship node that has an affiliation relationship with the DOI metadata in the data graph model, then create a corresponding first relationship node, and establish an association relationship between the DOI node and the first relationship node;
若判断所述数据图模型中不存在与所述DOI元数据具有引用关系第二关系节点，则创建对应的第二关系节点，并建立DOI节点与第二关系节点之间的关联关系。If it is judged that there is no second relationship node having a reference relationship with the DOI metadata in the data graph model, a corresponding second relationship node is created, and an association relationship between the DOI node and the second relationship node is established.
具体的，在创建完成DOI节点数据后，从数据图模型中查找是否存在与对象具有从属关系的第一关系节点，如果不存在，则自动创建一个第一关系节点，然后建立DOI节点与第一关系节点的关联关系，即将DOI节点与第一关系节点用有向箭头连接，并标明为从属关系。Specifically, after the DOI node data is created, it is searched from the data graph model whether there is a first relationship node that has a subordinate relationship with the object, if not, a first relationship node is automatically created, and then the DOI node and the first relationship node are established. The association relationship of the relationship node means that the DOI node and the first relationship node are connected by a directed arrow, and marked as a subordination relationship.
如果DOI节点有引用关系的第二关系节点，且在数据图模型不存在该第二关系节点，则自动创建一个第二关系节点，然后建立DOI节点与第二关系节点的关联关系，即将DOI节点与第二关系节点用有向箭头连接，并标明为引用关系。If the DOI node has a second relationship node of the reference relationship, and the second relationship node does not exist in the data graph model, a second relationship node is automatically created, and then the association relationship between the DOI node and the second relationship node is established, that is, the DOI node It is connected with the second relationship node with a directed arrow and marked as a reference relationship.
应当说明的是，在建立完成数据图模型后，可以对数据图模型进行挖掘，即在数据图模型界面中，点击节点，则展示关系节点和相关属性数据，进一步点击关系节点，则可挖掘该关系节点的关系，进一步展示下一级节点。It should be noted that after the data graph model is established, the data graph model can be mined, that is, in the data graph model interface, click a node to display the relationship node and related attribute data, and further click the relationship node to mine the data graph model. The relationship of the relationship node, further displaying the next level of nodes.
本发明实施例通过根据待查询DOI号从数据图模型中获取DOI节点数据及与待查询DOI号具有从属关系的第一关系节点，并根据引用关系层级获取第二关系节点，最后将构建的图谱作为查询结果发送至用户终端，使得用户能够直观的获取各个节点之间的引用关系。In the embodiment of the present invention, the DOI node data and the first relationship node having a subordinate relationship with the DOI number to be queried are obtained from the data graph model according to the DOI number to be queried, and the second relationship node is obtained according to the reference relationship level, and finally the constructed map It is sent to the user terminal as a query result, so that the user can intuitively obtain the reference relationship between each node.
在上述实施例的基础上，所述根据所述DOI号建立DOI节点，并将所述DOI号和对应的属性数据存储至所述DOI节点中，包括：On the basis of the above embodiments, the establishment of a DOI node according to the DOI number, and storing the DOI number and corresponding attribute data in the DOI node includes:
判断所述数据图模型中是否已存在所述DOI号，若存在，则将所述数据图模型中的所述DOI号对应的属性数据、具有从属关系的第一关系节点和具有引用关系的第二关系节点进行更新。Judging whether the DOI number already exists in the data graph model, if it exists, the attribute data corresponding to the DOI number in the data graph model, the first relationship node with an affiliation relationship, and the first relationship node with a reference relationship Two relationship nodes are updated.
具体的，由于对象的DOI元数据可能会发生变化，因此，在获取到构建数据图模型所需的对象的DOI元数据后，从DOI元数据中获取DOI号，判断DOI号是否已经存在数据图模型中，如果已存在，则说明需要更新数据图模型中的数据，此时，将数据图模型中该DOI节点中的属性数据、具有从属关系的第一关系节点和具有引用关系的第二关系节点全部删除，然后将重新获取到的对象的DOI元数据中的信息重新构建一遍，具体构建方法与上述实施例一致，此处不再赘述。Specifically, since the DOI metadata of the object may change, after obtaining the DOI metadata of the object required to build the data graph model, obtain the DOI number from the DOI metadata to determine whether the DOI number already exists in the data graph In the model, if it already exists, it means that the data in the data graph model needs to be updated. At this time, the attribute data in the DOI node in the data graph model, the first relationship node with affiliation relationship and the second relationship with reference relationship All the nodes are deleted, and then the information in the obtained DOI metadata of the object is reconstructed again. The specific construction method is consistent with the above-mentioned embodiment, and will not be repeated here.
本发明实施例通过判断数据图模型中已经存在DOI节点，则对该节点的信息进行更新，使得用户在查询时能够获得到更加准确的结果。In the embodiment of the present invention, by judging that a DOI node already exists in the data graph model, the information of the node is updated, so that the user can obtain more accurate results when querying.
