Summarization and Personal Information Management

This article explores the challenges of information overload and proposes a smarter summarization tool that utilizes user knowledge to provide new and relevant information. It discusses the interaction between the problem of information overload and human behavior, presents research findings on coping strategies, and suggests the need for improved information management techniques.

Presentation Transcript

  1. Summarization and Personal Information Management Carolyn Penstein Rosé Language Technologies Institute/ Human-Computer Interaction Institute

  2. Always know what problem you are trying to solve!!!

  3. Announcements • Questions? • Note: Only one student posted to Drupal • Homework 1 assigned today • Due Jan 25 at 8pm • Presented in class on Jan 26 • Plan for Today • Overview of Information Overload Literature

  4. Interesting Quote! • Using “typical” summarization will sure be useful and effective solution for the overload of information. However, its effectiveness will diminish as the person knowledge grows. This person will be faced with a frustrating situation of having to read, the same (summarized) information that he already know , again and again and again. The summarization tool that I propose will be smarter. It will ask the (or listen to) person to Input the knowledge that he already knows about the subject , by form of key words or full sentences. Then, the system will use the user knowledge in order to summarize the fact that the user DOES NOT know. The summarization tool will output NEW information for the user. This will make people information seeking, much more efficient, time saving, and way more fun. The OPPOSITE of what personalization techniques do!!

  5. Interaction between the problem and human behavior Problem Human Behavior Solution Design Technology Today’s focus Problem?

  6. Janssen and de Poot • Interesting! Started the investigation because an earlier attempt to increase information sharing seemed to increase information overload • Main finding: severity of information overload associated with strategies used to cope • Do the strategies cause the severity? • Or do people respond differently because the severity is different? • Are they stuck? Is there hope? Why do you think they chose to investigate senior managers?

  7. Methodology from Janssen & de Poot • Started with focal research questions • Structured interviews with target population • Experience with information overload • Coping strategies • Suggestions for what would help • Affinity diagramming  bottom-up clustering technique, allows categories to emerge Self-report? Is this a problem here? What about “small and skewed sample size”?

  8. Coping Strategies What is the real problem? Is there a design idea in here?

  9. What do you notice about the critical incidents?

  10. Textual Analysis Technique • Emergent People Clusters • Green [7] : non-sufferers • Red [4]: permanent-sufferers • Orange [4]: occasional sufferers • Some disagreement, resolved by consensus * Also different number of incidents per person.

  11. Can we do something with technology?

  12. What do you think?

  13. Student Quotes • Well, it seems to me that the article is telling us what really matters with information overload is not a tool or method but the person's life style. This actually discourages me from studying tools or ways of Personal Information Management because those who are good at managing their information would do well without any help of tool and those who don't won't do well even with a great tool.

  14. Moving on to cancer article…

  15. Information Literacy Can we do something about this? • Recognize an information need • Identify likely information sources and retrieve information • Assess quality and applicability of information • Understand and use information to make decisions You could think of information overload as the experience of not being able to do this effectively

  16. What do you think this means?

  17. What is information overload related to? • Too much information coming in • Ineffective Information Management • Don’t know what to attend to • Don’t know what to ignore • Stress or anxiety, feeling overwhelmed • Socioeconomic status, health status • Ambiguity • Don’t know the answer • Don’t know what to choose External Factors Behavioral Factors Affective Factors Personal Factors Cognitive Factors

  18. What can we do about this?

  19. How much of this can we influence?

  20. Cancer: Student Quote • With the wealth of healthcare related information available online, people now have access to more raw data. However, the information that they need is not a simple function of having access to data. Without the medical expertise and knowledge required previously provided by the doctors, there is too much to make sense of. This isn't just a case of there being too much for the time-constraints of the information-seeker. It is a case of insufficient expertise of the information-seeker to answer their own queries given the data.

  21. Student Comments • So it seems that the task of information summarization is not only to distill and compress the information, but also to provide more natural ways for helping people to manage the information effectively, guiding them to find better ways of coping information overload, and hopefully change their attitude towards the vast amount of information.

  22. Conclusion Our findings also have implications for the potentially larger role information professionals can play in the health arena. In particular, information professionals, in partnership with other community health resources and local health care providers, are particularly poised to provide training in information literacy skills to low literacy groups through public programs. Moreover, with some sensitivity training on various health issues, health information professionals will be able to deliver personalized information services to individuals who may have most need of assistance.

  23. Grand Challenges!!! • Multi-document summarization of scientific literature • Summarizing Web searches • Text Compression and Summarization for handhelds • Summarizing Social Interactions Grand Challenges

  24. Homework 1 (Due Jan 25, 8pm) • 1 page write-up, posted to Drupal • Feel free to post comments in response to write-ups submitted by your class mates • Select one of the Grand Challenges • Describe the scenario you are targeting • What is the main problem in connection with information overload here? • What is your proposed solution and why do you think it will work? • Mock up an example summary to illustrate your idea

  25. Information Overload in Different Contexts • Think about our grand challenge areas • What important characteristics do these three contexts share? • What important differences do you see? • Can there be one universal solution? Grand Challenges

  26. Example: How could you do this better?

  27. Another type of summary

  28. Yet another type of summary
