Decrypt the big technology behind the search engine: a knowledge map, the cornerstone of a large data semantic link

Knowledge Atlas, also known as the Atlas of Scientific Knowledge, it combines the theories and methods of applied mathematics, graphics, information visualization technology, information science, and other disciplines such as econometric citation Analysis, co-present analysis, and displays the core structure, development history and The Frontier field and the whole knowledge architecture reach the modern theory of multidisciplinary integration. Provide practical and valuable reference for subject research. -Baidu Encyclopedia

Entities and their diagrams. Size: 500 million objects, 3.5 billion facts and relationships-Wikipedia

The realization of the knowledge map to the objective world from the string description to the structured semantic description, is the knowledge mapping to the objective world (mapping worlds Knowledge)

Ontology can be used as a conceptual model and a logical basis for the representation of knowledge graphs

The knowledge map can describe the conceptual abstraction of different levels and granularity

Knowledge Atlas can be the foundation of Internet resource Organization

Although the vision of the semantic web has not yet happened, the development of the knowledge map is a good start for the internet to have a better knowledge of the world.

Multiple-meaning entries are often found in web searches. such as "Li Na" can represent the tennis player Li Na and singer Li Na. Usually the search results are given in the form of a list of results.

The semantic link of the Knowledge Atlas makes the search engine can use the entity based search instead of the string based search, so as to realize the ambiguity elimination in search.

The knowledge map makes the Internet from the string description to the objective world of specific things to describe, the Internet for the construction of Knowledge map provides a wealth of resources, knowledge map is the cornerstone of large data semantic links, knowledge map of the internet to understand the world's infrastructure.
