- Intelligence (disambiguation) [r]: Add brief definition or description
- Intelligence analysis [r]: Techniques, independent of the subject matter, for correlating multiple kinds of information, hypothesizing meaning from the set of data available, and, with incomplete information, validating the hypotheses [e]
- Intelligence collection management [r]: Assigning questions to various collection techniques, reflecting the techniques available and the priority of the information need. Includes the process of categorizing information learned for subsequent analysis, and assigning probabilities of accuracy to the raw information [e]
- Intelligence collection ontology [r]: The use of information technology and knowledge management to help map intelligence requests to the best available collection techniques [e]
- Intelligence cycle management [r]: The continuous process by which intelligence priorities are set, raw information collected, information analyzed, the processed information disseminated, and the next set or priorities set. [e]
