- the method of the present invention can add Web service description information to the existing knowledge graph, or it can first construct a local knowledge graph and then add Web service description information on this basis.
- Existing knowledge graphs such as current representative large-scale network knowledge bases including DBpedia, Freebase, YAGO, etc.
- the attribute value of each entity can be a simple type of numeric value/string, etc., or other entities.
- the relationship name is generally related to the data types of other entities. Take the flight plan information in Table 2 as an example. If a flight plan includes departure airport: Beijing Capital International Airport, landing airport: Shanghai Hongqiao Airport, then the flight plan is linked to Beijing Capital International Airport entity through DepartFrom, and Shanghai Hongqiao Airport is linked through ArriveAt .
- the construction statement based on neo4j is: MATCH(n:FlightPlan ⁇ ID:”MU564” ⁇ ),(m:Airport ⁇ ICAOID:”ZBAA” ⁇ )CREATE(n-[r:ArriveAt]->m)RETURN r.
- the result of the creation is shown in Figure 4. Other weather, runway and other information contained in Figure 4 will not be listed in detail here in tabular form.
- Web service publisher When a Web service publisher adds a Web service to the knowledge graph, it actually adds the description information of the Web service, not all the information that the Web can provide. When users need to query related data, they find a suitable Web service and send a request to it.
- the method of adding Web service description information is: first create a description entity for each Web service in the knowledge graph, and the attributes of the entity include service ID, service name and WSDL address; then add the relationship between the Web service entity and other entities for Describe the data that the web service can provide.
- the service entity is constructed based on neo4j, and the construction statement is: CREATE(n:WebService ⁇ ID:" ⁇ Metar", name:"North ChinaMetar", wsdl:"http://WebServiceURL/NorthChinaMetar?wsdl” ⁇ ).
- step S20 information query is performed based on the knowledge graph, and related Web service information is obtained according to the input query sentence.
- step S10 the process of information query and aggregation based on the knowledge graph constructed in step S10 is shown.
- the word segmentation tool is first used to segment the user's query sentence.
- word segmentation tools currently available, such as jieba, HanLP, etc., which can be selected according to specific business needs.
- Table 3 shows the correspondence between the user query statement template and the knowledge graph query statement.
- the user After the user enters the query statement, it is compared with the user query statement template to calculate the similarity.
- Current word segmentation software generally directly supports sentence similarity calculation. Select the most similar sentence template, and replace the keywords in the corresponding knowledge graph query sentence with the keywords in the user query sentence. For example, the user query sentence is "What is the landing airport of MU5183?" According to this sentence, it is most similar to the flight landing airport template.
- MU5183 conforms to the flight plan number.
- the flight plan number can be realized by regular expression, and the first two letters and the last four digits can be regarded as the flight plan number.
- the word segmentation result is "What is the landing airport of the flight plan MU5183". Replace FlightPlanNo in the knowledge graph query statement with MU5183, then you can construct the query statement MATCH(n:FlightPlan ⁇ ID:”MU5183” ⁇ )-[r:DepartFrom]->(m:Airport)RETURN m to get the result.
- the web service discovery process is similar to the template matching method, finds the web service most similar to the user's query sentence, and returns the service information.
- the most similar service is the flight data query service.
- the user searches the MU5183 landing airport according to the template in Table 4 to match the most relevant service query sentence. According to Table 5, the best match is the flight departure and arrival airport query service.
- the user calls the service according to the WSDL (Web Service Description Language) file automatically generated when the service is released.
- WSDL contains the message, function and other elements of the service, and describes how the service is called.
- Step S30 fusing the query result of the knowledge graph and the returned Web service query result.
- the truth discovery algorithm calculates the data source's voting value on the results based on the reliability of all data sources (knowledge graphs, web services) and the number of requests, and returns the result with the highest number of votes.
- the query result in the knowledge map is light rain
- the airport weather query service result is moderate rain
- the North China weather service query result is light rain.
- the returned results fall into two categories: light rain and moderate rain. Vote for each data source of the two types of results.
- Table 6 set the weights of 100 and 0.5 for the reliability and the number of requests respectively, and use the weighted sum to calculate the votes of each data source, which are 230, 175, and 128 respectively.
- light rain was 358 and moderate rain was 175.
- the credible result is light rain.
- Step S40 update the knowledge graph.
