(The purpose of the index is to speed up the query) For example, the following sentence speed will be increased: MATCH (Gene:person)-[:acted_in]->(M), (Other)-[:acted_in]->(m) WHE

Recently, on the basis of NEO4J Java API and RMI, a set of neo4j management tools is designed, which is divided into server side and client side, and communicates with RMI in middle. Basic functions include diagram database basic information Maintenance Management (creation, editing, deletion, statistics, etc.), graph database Data Maintenance management (create nodes and relationships, edit node and relati

There are two ways to use NEO4J: The embedding mode embedded and the server mode standalone, the bridge between the two is the neo4j-community-1.8.m03-windows\neo4j-community-1.8.m03\ The graph.db in data, which is replaced by the generated database folder in embedded mode, can be accessed from a generated database by 127.0.0.1:7474/webadmin in server mode.

Cypher Query Language simple to use3.1. Basic SyntaxNode syntax: The cypher uses a pair of parentheses to represent one of the nodes: Several formats are provided: () the anonymous node (matrix) adds an ID (: Movie) movie label label to the node, declaring the node type. The index of NOE4J uses label, each index consists of a label and a property (Matrix:movie) (Matrix:movie {title: "The Matrix"}) node attribute (for example: title) represents a Key\value list ( Matrix:movie {title: "The Matrix"

according to certain rules, usually only a subset of the sub-graphs can be accessed. The NEO4J database provides a declarative cypher language to query the graph, and neo4j generates a traversal scheme to query the graph. You can also specify the traversal scheme directly, specifying depth first or breadth first.Indexes in NEO4J can be used to speed up queries,

should be excavated further to increase the knowledge coverage of Knowledge Atlas. Common Mining Techniques: Inference: Mining for entity attributes or relationships through a rule engine for discovering unknown implied relationships Entity importance ordering: When querying multiple keywords, search engines will select entities that are more relevant to the query to display. Common PageRank algorithms compute the importance of entities in the knowledge map. Second,
