Actionable knowledge discovery is selected as one of the greatest challenges (Ankerst, 2002; Fayyad, Shapiro, & Uthurusamy, 2003) of next-generation knowledge discovery in database (KDD) studies (Han & Kamber, 2006). In the existing data mining, often mined patterns are nonactionable to real user needs. To enhance knowledge actionability, domain-related social intelligence is substantially essential (Cao et al., 2006b). The involvement of domain-related social intelligence into data mining leads to domaindriven data mining (Cao & Zhang, 2006a, 2007a), which complements traditional data-centered mining methodology. Domain-related social intelligence consists of intelligence of human, domain, environment, society and cyberspace, which complements data intelligence. The extension of KDD toward domain-driven data mining involves many challenging but promising research and development issues in KDD. Studies in regard to these issues may promote the paradigm shift of KDD from data-centered interesting pattern mining to domain-driven actionable knowledge discovery, and the deployment shift from simulated data set-based to real-life data and business environment-oriented as widely predicted.
Chapter Preview


In the last decades, data mining, or KDD, has become a prominent, exciting research and development area in the field of information technology. Data-centered data mining has experienced rapid development in various aspects such as data mined, knowledge discovered, techniques developed, and applications involved. Table 1 illustrates such key research and development progress in KDD.

Key Terms in this Chapter

Business Expectation: A pattern of interest to business needs satisfies business performance requests from aspects such as social, economic and psychoanalytic concerns.

Domain Driven Data Mining: Data mining methodologies and techniques that utilize domain-oriented social intelligence, target dependable, trustworthy and actionable knowledge for business decision making.

Statistical Significance: A pattern mined is statistically significant based on statistical metrics that measure and evaluate the performance of an identified pattern.

Interestingness: Measuring the performance of discovered knowledge in terms of statistical significance, user preference, and business expectation from objective and subjective perspectives.

Intelligence Metasynthesis: The interaction and integration between multiple types of intelligence surrounding a problem solving process, including human intelligence, data intelligence, domain intelligence and cyberspace intelligence. Advanced intelligence emerges through intelligence interaction and metasynthesis.

Social Intelligence: Intelligence hidden or reflected in aspects of data, domain, human, society and cyberspace where appropriate, for instance, domain-specific background information and knowledge, expertise, expert involvement, constraints, environment, business rules and processes.

In-Depth Mining: Mining patterns that disclose deep hidden information and relationship of attributes, which can assist deeper understanding of data, business and decision-making.

Business Decision Making: Decisions made by business people aim to the achievement of business objectives in a manner of satisfying business needs and expectations.
