    Dear Dr. Gemmell,

    I really enjoyed your paper “Improving Entity Resolution with Global Constraints” Is there any work that picked up your call to develop “graph matching algorithms that optimize precision/recall”?

    Thank you for all you do.

      Thanks! We did some more work in this space, see:
      Sahand Negahban, Benjamin I. P. Rubinstein, and Jim Gemmell, Scaling Multiple-Source Entity Resolution using Statistically Efficient Transfer Learning, in the Proc. 21st ACM International Conference on Information and Knowledge Management (CIKM 2012), pp. 2224-2228, October 2012 [journal full version submitted]
      and also on the problem of deciding what to do with conflicting information after entity matching:

    Dr Gemmell –
    I’m doing research for a book I am writing about memories and I came across some of the work you have done in this field. My story is nonfiction (Sci-Fi in a way). Would it be at all possible to chat with you regarding some questions I have – Thank you for your time.

    Dear Dr. Gemmell,
    I am a great admirer of your work and would like to invite you – on behalf of Prof. Stefan Selke – to contribute to an edited volume on lifelogging and sent an email to your former microsoft address. Unfortunately, my message came back since the address is no longer operational. Would you send me an email, so that I can forward the request once again?

    Thank you very much in advance and kind regards, Ines Hülsmann

    Dear Dr. Gemmell,

    For the last several months, I’ve been following developments in the Quantified Self movement and trying to put together a basic understanding of the MyLifeBits project. I originally came across your name in a CNET article, and have since delved into your book, Total Recall. It’s a shocking sort of forecast, yet I see evidence of its accuracy everywhere.

    I’d be interested to hear your take on whether certain information defies not only cataloguing, but recording in general. To me, human consciousness is so multi-layered that it challenges any kind of linear quantification. Thoughts often cross over into pre-verbal, image-laden territory, for example. Given that, I’d be like to hear your perspective on the evolution of e-memory. How do you anticipate technology transitioning from biometric renderings to more holistic representations? I’d also be fascinated to learn how you navigated the organizational challenges of MyLifeBits (creating your own Dewey decimal system, of sorts).

    Is there a way I could email you to set up an interview? I’m a journalist working on a story about lifelogging and the impulses behind it. Thanks for doing such incredible work and making it accessible to so many.

      I agree – its hard to see how human consciousness could be quantified. The total recall that is expanding is rather that of the sensory inputs to a human’s consciousness. Sensors increase, storage increases, and digital activities increase, but that leads to a life-log from a viewpoint just outside the human. How different the recall of the actual temperature from how cold I may have felt – and how different that perception often is between my wife and I, leading to thermostat battles 🙂 Perhaps we can infer, say, fear from increased heartbeats, or stimulation from brain alpha wave activity, but that is only a crude correlation.
      That is the limit of life-logging. However, seen in another light it is a benefit. My perception of temperature is often unreliable, my memories are often erroneous, and many things I am simply not conscious of, such as my heartrate, the humidity, or even the time. So, while missing my consciousness, the life log makes up for it in things I am not conscious of and in aspects where my consciousness is inaccurate.
