The Smart Lab: datamining.it.uts.edu.au BIA: BIA: Behavior Informatics and Analytics 15 December 2008Cao, L: BIA at DDDM2008 Joint with ICDM 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.

The Smart Lab: datamining.it.uts.edu.au BIA: BIA: Behavior Informatics and Analytics 15 December 2008Cao, L: BIA at DDDM2008 Joint with ICDM 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

The Smart Lab: datamining.it.uts.edu.au BIA: BIA: Behavior Informatics and Analytics 15 December 2008Cao, L: BIA at DDDM2008 Joint with ICDM 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)

The Smart Lab: datamining.it.uts.edu.au BIA: BIA: Behavior Informatics and Analytics 15 December 2008Cao, L: BIA at DDDM2008 Joint with ICDM Market price trend/movement estimation

The Smart Lab: datamining.it.uts.edu.au BIA: BIA: Behavior Informatics and Analytics 15 December 2008Cao, L: BIA at DDDM2008 Joint with ICDM 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.

The Smart Lab: datamining.it.uts.edu.au BIA: BIA: Behavior Informatics and Analytics 15 December 2008Cao, L: BIA at DDDM2008 Joint with ICDM 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

The Smart Lab: datamining.it.uts.edu.au BIA: BIA: Behavior Informatics and Analytics 15 December 2008Cao, L: BIA at DDDM2008 Joint with ICDM 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

The Smart Lab: datamining.it.uts.edu.au BIA: BIA: Behavior Informatics and Analytics 15 December 2008Cao, L: BIA at DDDM2008 Joint with ICDM 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

The Smart Lab: datamining.it.uts.edu.au BIA: BIA: Behavior Informatics and Analytics 15 December 2008Cao, L: BIA at DDDM2008 Joint with ICDM 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

The Smart Lab: datamining.it.uts.edu.au BIA: BIA: Behavior Informatics and Analytics 15 December 2008Cao, L: BIA at DDDM2008 Joint with ICDM 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 behavior and 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;

The Smart Lab: datamining.it.uts.edu.au BIA: BIA: Behavior Informatics and Analytics 15 December 2008Cao, L: BIA at DDDM2008 Joint with ICDM mapped behavior direct or indirect mapping of physical behavior in a virtual world.
