Refers to information obtained by analyzing public information or other resources.

Principles of open source intelligence:

1, data mining: a full coverage collection method of distributed big data, which captures effective data from open source network information.

2. Data filtering: visual query searches data of any type and format, automatically matches and extracts duplicates, and realizes data quality monitoring.

3. Data analysis: interlocking data processing module, combining multidimensional analysis framework and related logic engine, establishing a complete data analysis framework.

4. Data visualization: construct an analytical mind map and provide a visual information sorting report.

Extended data

Research methods of open source intelligence;

1, mathematical analysis method:

Many branches of modern mathematics are applied to the research of information science. Such as probability theory, set theory, fuzzy mathematics, differential equations, operational research and so on. It can be applied to the determination of information retrieval theory, information transmission mechanism and information collection scheme, even number theory, graph theory, functional analysis and variational method.

2, system analysis and evaluation methods:

Methods of system analysis and evaluation. By introducing system theory and other methods, we can analyze, evaluate, plan and design all aspects and the whole information system. Choose the best method to get the best result.
