Personalization Process-(1) a Personalization constitutes an iterative process that can be defined by the Understand-De/lver-Measure cycle Understand consumers by collecting comprehensive information about them and converting it into actionable knowledge stored in consumer profiles Deliver personalized offering based on the knowledge about each consumer, as stored in the consumer profile Measure personalization impact by determining how much the consumer is satisfied with the delivered personalized offering Measure the personalization Impact Understand the visitors f Deliver personalized content CEBT Center for E-Business Technology Copyright o 2008 by CEBT

Personalization Process-3) 1. Data Collection The objective is to obtain the most comprehensive picture of a consumer Various and heterogeneous data sources(Web phone, mail ,) Can be solicited explicitly or tracked implicitly 4. Delivery and presentation Delivery Method Push: Reaches a consumer who is not currently interacting with the system Pull Notify consumers that personalized information is available but display this information only when the consumer explicitly requests it Passive: displays personalized information as a by-product of other activities of the consumer Presentation Ordered by relevance unordered list of alternatives, or various types of visualization CEBT Center for E-Business Technology Copyright o 2008 by CEBT

Delivery and Presentation ◼ Delivery Method – Push : Reaches a consumer who is not currently interacting with the system – Pull : Notify consumers that personalized information is available but display this information only when the consumer explicitly requests it – Passive : displays personalized information as a by-product of other activities of the consumer ◼ Presentation – Ordered by relevance, unordered list of alternatives, or various types of visualization Center for E-Business Technology

Measuring Personalization Impact Various accuracy metrics can be used to evaluate the personalization Consumer lifetime value loyalty value purchasing and consumption experience The quality of recommendations depends on the previous stages 6. Adjusting Personalization Strategy Feedback can be used to identify a part that needs improvements a The quality of interaction should grow over time One of the main challenges of personalization is the ability to achieve the virtuous cycle of personalization and not to fall into the de-personalization trap CEBT Center for E-Business Technology Copyright o 2008 by CEBT

Building consumer profiles a Traditionally, consumer profiles consist of simple factual information Name, gender, date of birth The largest purchase value made at a Web site a Advanced behavioral information can be expressed by Conjunctive Rules John Doe prefers to see action movies on weekends Name= John doe"& movietype = action"->TimeofWeek="weekend Sequences XYZ: StartPage->Home& Gardening ->Gardening->Exit Signatures The data structure that are used to capture the evolving behavior learned from large data streams of simple transactions Top 5 most frequently browsed product categories over the last 30 days typedef struct i int product _id[5];s profile CEBT Center for E-Business Technology Copyright o 2008 by CEBT

Matchmaking Technologies -(1) a Classification based on the recommendation approach Content-based recommendations Analyze the commonalities among the items the consumer has rated highly in the past. Then, only the items that have high similarity with the consumer's past preferences would get recommended Collaborative Recommendations Find the closest peers for each consumer, i. e. the ones with the most similar tastes and preferences. Then, only the items that are most liked by the peers would get recommended ■ Hybrid Approaches Combine collaborative and content -based methods This combination can be done in many different ways CEBT Center for E-Business Technology Copyright o 2008 by CEBT
