    1. Uniscript: a Model for Persistent and Incremental Knowledge Storage Adorjan Kiss, Joel Quinqueton LIRMM, Montpellier, France

    2. 6/30/2012 Uniscript 2 Objective (a world to dream of) The knowledge of a person gathered and instantly accessible anytime by anyone. Each piece of knowledge should be “true”. Its truth should be “guaranteed” by the author. Each piece of knowledge should be unique. Access to a piece of knowledge should be possible through any related piece of knowledge.

    3. 6/30/2012 Uniscript 3 Personal Knowledge Representation Knowledge representation in computers: To be used in foreseen scenarios Knowledge elements considered universally accepted (“information”). The objective: De-couple knowledge from expected usage. A piece of knowledge can be recorded not only when its utility is certain. People may feel a piece of knowledge is important, without being able to explain why. Record permanently. Represent only knowledge that you are certain of. That is, you believe to have the least chances to become “invalidated” by time. KR in history seen with 2 major constraints Foreseen = not stored just for the fun of it Information – a word I’m sore with Start with events and situated phenomena KR in history seen with 2 major constraints Foreseen = not stored just for the fun of it Information – a word I’m sore with Start with events and situated phenomena

    4. 6/30/2012 Uniscript 4 What is “everlasting” knowledge? A seemingly obvious answer: Perfect classifications The unquestionable rules of our physical world. The alternative answer: Objects, events, facts that had a real existence. That is, “situated” knowledge. “Les theories passent, les grenouilles restent” (Theories pass, the frogs remain) - Jean Rostand Ok, but these individual pieces of knowledge (the frogs) are countless. Can’t hope to represent everything. Which ones to choose? Everything important for a person: see Memex. Situated: space and time What is persistent are not classes, but instances Ppt de Gordon Bell ici (Vannevar Bush, 1945, without technologies) It costs more time to delete than the cost of storage Hierarchies are a constraining model, files as blobs, entities and links http://research.microsoft.com/~gbellSituated: space and time What is persistent are not classes, but instances Ppt de Gordon Bell ici (Vannevar Bush, 1945, without technologies) It costs more time to delete than the cost of storage Hierarchies are a constraining model, files as blobs, entities and links http://research.microsoft.com/~gbell

    5. 6/30/2012 Uniscript 5 Situated knowledge pieces Observer: the person who contemplates the world His attention is attracted by certain “phenomena” that he can delimit, identify an trace through a period of time. Stance: A delimitation (cut-out) from the world (space-time continuum) that presented an importance for the observer. Its borders – in space, and time – are subjective They can be fuzzy The observer is not constrained to agree with anyone else about where he draws the borders. It presents some regularities – the features allowing the observer to trace it – (hence the name “stance”)

    6. 6/30/2012 Uniscript 6 Stancification What to stancify? Final objective: progressively learn to store everything a human mind can represent and explicit. How to select what to stancify next? Lasting importance. A stance should be found interesting beyond a foreseen usage scenario. Guidance by strength of belief. No surprise is expected that could contradict the reality of a stance. Principle of uniqueness. Before recording a stance, make sure it is not already there.
