I have been studying how to make echarts relationship diagram in the morning. echarts has two official websites, one is echarts3 and the other is echarts2. I have been using echarts3, and there are several complicated examples in it. It is to call an xml. This xml is a famous relationship diagram (only draw relationship diagrams?). The software Gephi exports the format gexf. The first idea was to dynamically generate this xml. Later, I found it a bit complicated, and then I looked at a few more A simple example, combined with the documentation, shows that it can be written directly in json format, involving

Article Introduction：1. Graph Overview First introduce some basic concepts of knowledge graph. 1. What is knowledge graph? Knowledge graph aims to use graph structures to model, identify and infer complex relationships between things and precipitate domain knowledge. It is an important cornerstone of realizing cognitive intelligence and has been widely used in search engines and intelligent question answering. , language semantic understanding, big data decision analysis and many other fields. The knowledge graph models both the semantic relationship and the structural relationship between data. Combined with deep learning technology, the two relationships can be better integrated and represented. 2. Why should we build a knowledge graph? We want to build a knowledge graph mainly from the following two points: on the one hand, the characteristics of the data source background of ants themselves, and on the other hand, the benefits that the knowledge graph can bring. [1] The data sources themselves are diverse and heterogeneous.

Article Introduction：1. Graph databases and knowledge graphs will become the dominant force in 2022. Many people predict that graph databases will become the secret weapon in 2022. Carl Olofson, research vice president at IDC, expects graph database usage to grow 600% over the next 10 years, starting this year. In an article written by analyst Dave Vellante, a summary of how to take advantage of a typical relational database’s uses and limitations: “With a relational database, you can [find relationships and see how many levels there are in the chain], but this It requires a lot of programming. In fact, you can do almost any of the above using a relational database, but the problem is, you have to program it. Whenever you have to program it, it means you can't track it, you can't determine it.

Article Introduction：Good software is not discovered by program analysis and error detection, but is built by the right people. Graphs have become an increasingly important computing object. The graph structure is an abstraction of group relationships and can describe rich objects and relationships. The core of graph computing is how to model data into a graph structure and how to transform the solution of the problem into a computing problem on the graph structure. When the problem involves correlation analysis, graph computing can often make the solution to the problem naturally expressed as a A series of operations and calculations on graph structures. For example, the PageRank algorithm based on the graph structure of web page links is used to obtain the weight of the web page, which is used as a reference for search engine ranking. The user behavior data of the graph structure is used to obtain accurate group preference analysis and personalized product recommendation results. 1.What is plotting?

Article Introduction：Introduction MongoDB is a product between a relational database and a non-relational database. It is the most feature-rich among non-relational databases and is most like a relational database. The data structure it supports is very loose and is a bson format similar to json, so it can store more complex data types. The biggest feature of Mongo is that the query language it supports is very powerful. Its syntax is somewhat similar to an object-oriented query language. It can almost implement most functions similar to single-table queries in relational databases, and it also supports indexing of data. 1. Download the Linux installation package as shown below and place it in a local corner. Remember the location~ 2. Connect to your server sshroot@your IP//Enter and enter the password 3.

Article Introduction：Graph Retrieval Enhanced Generation (GraphRAG) is gradually becoming popular and has become a powerful complement to traditional vector search methods. This method takes advantage of the structural characteristics of graph databases to organize data in the form of nodes and relationships, thereby enhancing the depth and contextual relevance of retrieved information. Graphs have natural advantages in representing and storing diverse and interrelated information, and can easily capture complex relationships and properties between different data types. Vector databases are unable to handle this type of structured information, and they focus more on processing unstructured data represented by high-dimensional vectors. In RAG applications, combining structured graph data and unstructured text vector search allows us to enjoy the advantages of both at the same time, which is what this article will discuss. structure
