"knowledge map" is a word in the big data industry, a data structure, or a method of using data. To put it academically, it can be understood as follows:

Knowledge map is essentially a semantic network, and it is a graph-based data structure, consisting of nodes and Edge. In the knowledge map, each node represents the "entity" existing in the real world, and each edge is the "relationship" between entities. Knowledge map is the most effective way to express relationships. Generally speaking, knowledge map is a relational network that connects all different kinds of information together. Knowledge map provides the ability to analyze problems from the perspective of "relationship".

Just like watching a criminal investigation film, the police will list a bunch of relationships between prisoners and victims. Knowledge map is to connect different information in series to form a network of relationships, so as to find what you need in the network.

If you look up Baidu, you will find that Baidu, Google and others are using knowledge mapping technology. For example, if you search for "in the name of people", Baidu will recommend the characters in the play to you on the right, and when you click in, people will be introduced. This is the information network extended by "in the name of people".

An American company called Palantir played a particularly good role in this technology, helping the United States catch bin Laden. Palantir's story can be seen here, which explains the principle behind the big data solution mentioned in the title.
