  2. Outline • Motivation • Behavior and Behavioral Model • BIA Framework • BIA Theoretical Underpinnings • BIA Research Issues • BIA Applications & Case Studies • BIA References Cao, L: BIA at DDDM2008 Joint with ICDM2008

  3. Motivation • Behavior is an important analysis object in • Business intelligence • Customer relationship management • Social computing • Intrusion detection • Fraud detection • Event analysis • Market strategy design • Group decision-making, etc. Cao, L: BIA at DDDM2008 Joint with ICDM2008

  4. Examples • Customer behavior analysis • Consumer behavior and market strategy • Web usage and user preference analysis • Exceptional behavior analysis of terrorist and criminals • Trading pattern analysis of investors in capital markets Cao, L: BIA at DDDM2008 Joint with ICDM2008

  5. Traditional analysis on behavior • Behavior-oriented analysis was usually conducted on customer demographic and transactional data directly • Telecom churn analysis, customer demographic data and service usage data are analyzed to classify customers into loyal and non-loyal groups based on the dynamics of usage change • outlier mining of trading behavior, price movement is usually focused to detect abnormal behavior so-called behavior-oriented analysis is actually not on customer behavior-oriented elements, rather on straightforward customer demographic data and business usage related appearance data (transactions) Cao, L: BIA at DDDM2008 Joint with ICDM2008

  6. Market price trend/movement estimation Cao, L: BIA at DDDM2008 Joint with ICDM2008

  7. Problems with traditional behavior analysis • customer demographic and transactional data is not organized in terms of behavior but entity relationships • human behavior is implicit in normal transactional data: behavior implication • cannot support in-depth analysis on behavior interior: behavior exterior • Cannot scrutinize behavioral intention and impact on business appearance and problems Such behavior implication indicates the limitation or even ineffectiveness of supporting behavior-oriented analysis on transactional data directly. Cao, L: BIA at DDDM2008 Joint with ICDM2008

  8. behavior can make difference • behavior plays the role as internal driving forces or causes for business appearance and problems • complement traditional pattern analysis solely relying on demographic and transactional data • Disclose extra information and relationship between behavior and target business problem-solving A multiple-dimensional viewpoint and solution may exist that can uncover problem-solving evidence from not only demographic and transactional but behavioral (including intentional, social and impact aspects) perspectives Cao, L: BIA at DDDM2008 Joint with ICDM2008

  9. support genuine behavior analysis • make behavior ‘explicit’ by squeezing out behavior elements hidden in transactional data • a conversion from transactional space to behavior feature space is necessary • behavior data: • behavior modeling and mapping • organized in terms of behavior, behavior relationship and impact Explicitly and more effectively analyze behavior patterns and behavior impacts than on transactional data Cao, L: BIA at DDDM2008 Joint with ICDM2008

  10. main goals and tasks of behavior informatics and analytics (BIA) • behavioral data construction • behavior modeling and representation, • behavior impact modeling, • Behavior pattern analysis, and • behavior presentation BIA is mainly from the perspectives of information technology and data analysis rather than from social behavior aspect Cao, L: BIA at DDDM2008 Joint with ICDM2008

  11. BIA makes difference • Case study: churn analysis of mobile customers • analysis on demographic and service usage data • behavior sequences of a customer • activities happened from his/her registration and activation of a new account into a network • Characteristics of making payments to the date leaving the network • Know deep knowledge about mobile service retainer’s intention, activity change, usage dynamics, and payment profile • disclosing reasons and drivers of churners and their loyalty change Cao, L: BIA at DDDM2008 Joint with ICDM2008

  12. So, what is behavior • Under the scope of Behavior Informatics and Analytics, behavior refers to those activities that present as actions, operations or events, and activity sequences conducted by human beings under certain context and environment, as well as behavior surroundings. • the informatics and analytics for symbolic behaviorand the analytics of mapped behavior. • symbolic behavior • Those social activities recorded into computer systems, which present as symbols representing human interaction and operation with a particular object or object system; • place an order • game user behavior • intelligent agent behavior; Cao, L: BIA at DDDM2008 Joint with ICDM2008

  13. mapped behavior • direct or indirect mapping of physical behavior in a virtual world. • Those physical activities recorded by sensors into computer systems, • human activities captured by video surveillance systems; • robot’s behavior • organism’s behavior in game systems; Cao, L: BIA at DDDM2008 Joint with ICDM2008

  14. An Abstract Behavioral Model • Behavior attributes and properties: • Subject (s): The entity (or entities) that issues the activity or activity sequence; • Object (o): The entity (or entities) on which a behavior is imposed on; • Context (e): The environment • Goal (g): Goal represents the objectives • Belief (b): Belief represents the informational state and knowledge • Action (a): Action represents what the behavior subject has chosen to do or operate; • Plan (l): Plans are sequences of actions • Impact (f): The results led by the execution of a behavior on its object or context; • Constraint (c): Constraint represents what conditions are taken on the behavior; constraints are instantiated into specific factors in a domain; • Time (t): When the behavior occurs; • Place (w): Where the behavior happens; • Status (u): The stage where a behavior is currently located; • Associate (m): Other behavior instances or sequences of actions that are associated with the target one; Cao, L: BIA at DDDM2008 Joint with ICDM2008

  15. An abstract behavior model • Demographics of behavioral subjects and objects • Associates of a behavior may form into certain behavior sequences or network; • Social behavioral network consists of sequences of behaviors that are organized in terms of certain social relationships or norms. Cao, L: BIA at DDDM2008 Joint with ICDM2008

  16. behavior instance: behavior vector • basic properties • social and organizational factors • vector-based behavior sequences, • vector-oriented patterns. Cao, L: BIA at DDDM2008 Joint with ICDM2008

  17. vector-oriented behavior pattern analysis is much more comprehensive • Behavior performer: • Subject (s), action (a), time (t), place (w) • Social information: • Object (o), context (e), constraints (c), associations (m) • Intentional information: • Subject’s: goal (g), belief (b), plan (l) • Behavior performance: • Impact (f), status (u) • New methods for vector-based behavior pattern analysis Cao, L: BIA at DDDM2008 Joint with ICDM2008

  18. The concept of BIA • BIA aims to develop methodologies, techniques and practical tools for • representing, modeling, analyzing, understanding and/or • utilizing symbolic and/or mapped behavior, • behavioral interaction and network, behavioral patterns, • behavioral impacts, • the formation of behavior-oriented groups and collective intelligence, and • behavioral intelligence emergence.
