  1. Overview of Personal Web Management(PWM) Presenter: Azrina Kamaruddin Supervisor: Prof. Alan Dix HUMAN'S WEEKLY SEMINAR

  2. Introduction • PIM and PWM • Empirical Results • Application Development • Issues for discussion HUMAN'S WEEKLY SEMINAR

  3. Introduction • Growth of information • The growth of information increases dramatically faster every second and every beat in our life. • Managing information is not easy for certain people. • Use with files and piles which give us cues for reminding. • Deals with different type of information. • Technology • The way information presented to us comes to us in various ways. • People are fascinated with the Internet, however, problems occur with the tools provided with the WWW browser. HUMAN'S WEEKLY SEMINAR

  4. Classification • PIM (eg: Outlook, Online Diary etc) • Context aware app. • CyberMinder(Anind K.Dey) • Stick-E note ( Schillit) • PWM (revisitation tools, e-mail etc) HUMAN'S WEEKLY SEMINAR

  5. PIM • Evolution of PIM Paper Calendar To-do list, Diary Book, etc Automatic Diary, PIM app. Web application, Online PIM app., bookmark Paper based Laptop, Mobile, PDA’s HUMAN'S WEEKLY SEMINAR

  6. Personal Information Mgt (PIM) • Why we need it? • To manage ourselves • To maintain information • To aid as a reminder • Any others? HUMAN'S WEEKLY SEMINAR

  7. Personal Web Information Spaces • WWW phenomena • Just by a click of your finger • Listing of information provided • Hypertext and hypermedia • Searching WWW user behaviour • The user behaviour when using the WWW. • Empirical results showing how people use revisitation tools HUMAN'S WEEKLY SEMINAR

  8. Empirical results Abrams, Baecker & Chignell(1998), - Bookmarks are created and stored for archival purposes and often not visited. • As the number of items increased in the bookmark list, the user tends to group it into hierarchies of folders. • Users with 300+ bookmarks tend to file at the same time of creation because they must keep an up-to-date archive in order to manage so many bookmarks. HUMAN'S WEEKLY SEMINAR

  9. Empirical results Tausher and Greenberg (1997a, 1997b), • Users revisit a considerable number of web pages. 58% probability that the next page visited was previously seen is based on the analysis of recurrence rate. • Reported that the Back button is one of the fundamental revisitation tool used frequently (30% of all navigation actions). • Methods to present a history list of previously visited pages are available that are more predictive and usable than the current stack-based approach. HUMAN'S WEEKLY SEMINAR

  10. Empirical results Jones, Dumais and Bruce (2001) **** • Reported that the history list is not on the top list for user to use this mechanism. • E-mail is quite a popular tool for the user to send the URL to themselves and colleagues. • Results HUMAN'S WEEKLY SEMINAR

  11. Empirical results HUMAN'S WEEKLY SEMINAR

  12. Empirical results Analysis of function • Portability of information • Number of access points • Persistence of information • Preservation of information in its current state • Currency of information • Context • Reminding • Ease of integration • Communication and information sharing • Ease of maintenance HUMAN'S WEEKLY SEMINAR

  13. Application Shared bookmark system by Kanawati and Malek (2000) If bookmark need to become an effective user’s customized gate to the Internet, three problems at least need to be handled: • The resource discovery problem • The bookmark recall problem • The bookmarks maintenance Problems with the existing system:- • The weak customization of shared spaces • The lack of efficient and easy to use privacy protection policies • The adoption of centralized architectures that affects badly responsiveness, availability and dependability of these systems HUMAN'S WEEKLY SEMINAR

  14. Application Kanawati and Malek (2000) Motivations of the collaboration • Personal assistant agent • Collaborative approach Solve: -The development of CoWing (Collaborative Webdexing) -The aim of allowing an organized group of people to share their experiences in managing bookmarks HUMAN'S WEEKLY SEMINAR

  15. Application Integrated Bookmark/History system for Web Browsing by Kaasten and Greenberg (2000) Problems:- • User perspective • user having problem to get information they already found • The mechanisms – back, history list and bookmark - incorrect model of the way it works - used it infrequently - different interfaces Solutions:- • Integrate the back button with history list • Implicit/explicit bookmark • Search filters • Page recognition HUMAN'S WEEKLY SEMINAR

  16. Application WebStickers by Ljungstrand, Redstorm and Holmquist (2000) Problems : -Bookmark to manage but they rarely have time to do that and also with the cognitive overhead such as where they put their document. - Different kind of approach and interface technology such as information visualization, adaptive agent and other automatic bookmark organization tools. HUMAN'S WEEKLY SEMINAR

  17. Application Solution Different kind of approach – tangible media • Use scanner • Tagging with physical objects – affordances • Aid reminding HUMAN'S WEEKLY SEMINAR

  18. Issues Management • How can information management principles influence the revisitation tools? • Does all the principle of management applied? • How people want to manage their web document? • Why they rarely used bookmark/history list? • Is it the human problem or design problems? • Why people use email rather than bookmark? • What is it in email which they prefer to use despite ease creating the bookmark? HUMAN'S WEEKLY SEMINAR

  19. Issues Classification and categorization • When to do both? • How to do it? • Does user easily recognize an item by looking at its classification? Sorting • When? Interfaces • Naming • Metaphor HUMAN'S WEEKLY SEMINAR

  20. Issues Critical mass problem • Worth the effort and cost of doing it • To understand the user cognitive effort and physical aspect Query and bookmark management • Is there any relationship between query that you make with the document that you find and store. • What is the effect of not keeping query and web document? HUMAN'S WEEKLY SEMINAR

  21. Issues Collaboration • How can bookmark support collaboration? • How we disseminate information? • How we keep that information from others who send to us? • Where you keep them? • How accessible it is? HUMAN'S WEEKLY SEMINAR

  22. Issues Finding and Reminding • How can this issue support bookmark? • Does we really need a reminder in bookmark? Awareness • How can this issue support bookmark? • Does we really need a awareness in bookmark? • What is the difference between awareness and reminder? • Complement each other? Reuse and Reaccess • To understand people behaviour of retrieving information • The frequency of they do this activity • How easily we get to know that the document is in there? HUMAN'S WEEKLY SEMINAR

  23. Some ideas- Any Comments • Integrating the query and bookmark management to support collaboration. • Since e-mail is popular, thinking of using e-mail as a mechanism and grab the URL from e-mail and keep it in bookmark and also categorize it. How to keep the link permanent? HUMAN'S WEEKLY SEMINAR
