The Methods of Information Analysis in Data Intelligence Era:Data Driven,Knowledge Driven,and Fusion Driven by Data and Knowledge
Facing the challenge from big data and big knowledge in the era of data intelligence,how to innovate information analysis methods is vital for the information analysis work and data resources development.Information analysis(intelligence analysis,intelligence research or intelligence investigation)aims to meet the users'special intelligence need,analyse and mine big data,information and knowledge,provide users integrated,systematic,real-time,in-depth decision support based on the processes of collection,processing,mining,analysis,and prediction.In the era of data intelligence,information analysis needs to transfer from small data or small knowledge to big data and big knowledge.Especially,the analysis methods need to try to integrate big data and big knowledge to avoid the limitation and paradox from data.Based on the review of related research,this paper proposes three data intelligence paths of information analysis:data driven information analysis methods,knowledge driven information analysis methods,and fusion driven by data and knowledge information analysis methods.First,we depict the data driven information analysis model separately from text data,network data,audio data,image data and corresponding text mining,graph mining,audio mining,and image mining methods;second,we depict the knowledge driven information analysis model separately from expert knowledge base,general knowledge base,domain knowledge graph,and general knowledge graph;third,we depict the fusion driven information analysis model by data and knowledge separately from the feature level,model level,and decision level.The findings may contribute to construct a systematic information analysis method framework fusing big data and big knowledge,provide methods guidance for data intelligence information analysis,promote the methodology development of LIS,and empower the government decision-making and social governance.3 figs.1 tab.59 refs.
