Big date issues
Data analysis and mining problems
The core role of data analysis and mining in big data applications
Common data analysis and mining problems, such as information extraction, knowledge discovery, pattern recognition, etc.
Causes of these problems, such as algorithm complexity, model validity, result interpretability, etc.
Possible ways to solve these problems, such as optimizing algorithms, selecting models, increasing visualization, etc.
Data management and governance issues
Data management and governance are the basic support for the big data ecosystem
Common data management and governance issues, such as standardization, standard implementation, rights and interests protection, etc.
The causes of these problems, such as conflicts of interest, lagging laws, lack of supervision, etc.
Possible ways to solve these problems, such as establishing a coordination mechanism, improving the regulatory system, strengthening supervision responsibilities, etc.
Data quality and safety issues
The importance of data quality and security for big data analysis
Common data quality and security issues, such as missing, wrong, inconsistent, outdated, redundant, leaked, tampered, etc.
Causes of these problems, such as collection method, storage format, transmission process, usage permissions, etc.
Possible ways to solve these problems, such as cleaning, verification, encryption, backup, etc.
