The specific method for matching, fusing and updating according to various unique identifiers in the request comprises the following steps:
1) First, a unique identifier is determined, with reference to the attributes of the scientific and technological entities in table 1, for example, for scientific and technological achievements, PMCID, PMID, DOI are three different types of unique identifiers, but when a data request is made, only one type of unique identifier of PMCID may exist in a specific domain knowledge base, and then complete matching can be performed with the one type of unique identifier of PMCID, so as to find out an entity that is the same as the PMCID in the central scientific and technological domain knowledge graph.
2) And returning the matched entities and attributes in the knowledge graph of the central science and technology field, and fusing the entities and the knowledge graph of the specific science and technology field. One relatively common blending rule is: and when the same attribute category exists but the entity attribute value in the specific domain knowledge graph and the returned entity attribute value are not empty, fusing by taking the specific domain knowledge graph data as reference. Other fusion rules exist, for example, when the same attribute category exists but neither the entity attribute value in the domain-specific knowledge graph nor the returned entity attribute value is empty, fusion is performed based on the latest data.
3) And after the acquired scientific and technological entities and the acquired relational data are matched and fused, updating the data into a knowledge base in the specific field.

TABLE 6 content of feedback
| Feedback content | Description of the invention |
| Feedback categories | The category for data feedback includes identification correspondence, comparison error, comparison combination and the like |
| Details of the feedback | For different feedback categories, feedback of detailed data is performed. |
The identification correspondence refers to various unique identifiers, such as the correspondence of the PMCID, mainly whether the correspondence exists or not and how the correspondence exists; the contrast error means that the data of the knowledge graph in the central science and technology field is wrong during fusion; the contrast combination means that the central science and technology domain knowledge map data and the existing specific domain knowledge base data can be combined during fusion.
6. Central science and technology domain knowledge map updating
And updating the knowledge graph of the central science and technology field according to the feedback data, and adding the identification of the service object.
The step of updating the knowledge graph in the central science and technology field comprises the following steps:
1) If the unique identifier is corresponding, if PMCIDA exists in the specific domain knowledge base of the specific domain, PMCID exists in the knowledge map of the central science and technology domain, and the feedback details are that the PMCID and the PMCIDA can correspond, the PMCID in the knowledge map of the central science and technology domain is recorded, and the PMCID in the knowledge map of the specific domain is in one-to-one correspondence with the PMCIDA of the knowledge base of the specific domain.
2) And if the comparison is wrong, correcting the entity and relationship attribute of the central science and technology field knowledge graph with the wrong comparison according to the feedback details of the comparison.
3) And if the comparison and combination are carried out, correcting the entity and the relationship attribute of the central science and technology field knowledge graph with error comparison according to the comparison and combination feedback details.
The method for adding the identifier comprises the following steps: and adding a specific domain knowledge base identifier in the knowledge graph of the central scientific and technological domain. For example: adding a 'CNIC _ NI _ XXX' identifier for a network information knowledge base of a computer network information center of Chinese academy of sciences in entities and relations returned by a knowledge graph in the central science and technology field. Wherein the prefix "CNIC _ NI" uniquely identifies the network information repository of the computer network information center of the academy of sciences of china, and "XXX" is a unique identifier in a specific domain that matches table 1.
