Collabora've Learning in the Digital Social Medium Prof. Pierre Lévy @plevy Fellow of the Royal society of Canada Canada Research Chair in Collec've Intelligence University of OFawa Spring 2010 Outline of the Presenta'on • Symbolic cogni'on and media-‐augmented cogni'on • Dialec'c of personal and social knowledge management in social media • Problems of cogni've interoperability. How to exploit the new computa'onal possibili'es in the service of human collec've intelligence? • Toward a new layer of seman'c addressing in the digital medium • Models of computa'onal collec've intelligence, philosophical perspec'ves. Symbolic Cogni'on • Socially coordinated symbolic processing – Class of phenomena represen'ng categories – Explicit categorisa'on of sense data and symbolic processes – Communica'on of symbolic memory • Reﬂexivity – Mapping and re-‐mapping phenomena – Self-‐reference, self-‐representa'on of cogni've processes – Ques'onning, awareness of ignorance • Dialogue – Exchange of ideas and narra'ves, representa'on of the cogni've processes of other people – Nego'a'on of meaning and decisions – Social norms for reasonning and interpreta'on, common understanding of complex models • Narra'vity – Symbolic models of complex causal phenomena (actors, objects, quali'es, processes). Not limited to tradi'onal tales. Evolu'on of Mediasphere (From 2000) Ubiquity, interconnection and automatic manipulation of symbols. Social Media. New sign systems. Knowledge economy (From 1500) massive technical self-reproduction and diffusion of the alphabet and other cultural signs. New languages (animated images, etc.) Scientific notation progress. Industrial economy (From - 1000) Digitization and universalization of writing reduced to thirty phonetic signs. Notation of numbers by position, zero. Commercial economy (From - 3000) Autonomous technical memory of language. Idéographic Signs. Numerals, measurement units. Agricultural economy (From - 300 000) myths, rites, oral transmission, memory inscribed in matter. Icons. Arts of memory. Hunting-gathering economy Personal Knowledge Management Cycle 1. AFen'on management – Deﬁne interests, priori'es, areas of exper'se (acquired and aimed). Stay focused, avoid distrac'on, keep in mind the big picture 2. Connec'on to valuable sources – Informa'on streams from people and ins'tu'ons 3. Gathering and aggrega'on of data streams 4. Filtering – Manual and automa'c (according to 1) 5. Categoriza'on – Tagging, classiﬁca'ons, ontologies 6. Recording for long-‐term memory – Social bookmarking, ar'cles and library management tools, cloud memory 7. Synthesis – Blog posts, ar'cles, wiki entries 8. Sharing, communica'on – Pos'ng result of 4, 5, 6, 7 on social media. Replies, crea've dialogue 9. Reassess: aFen'on management, connec'ons, categoriza'on, PKM tools Social Knowledge Management Cycle Three movements People transform Implicit knowledge of a prac'ce into common explicit knowledge (centripetal) and vice versa (centrifugal) through PKM implied in CCC (circular) Implicit Knowledge PKM PKM PKM Civilized Crea8ve Conversa8on PKM PKM Common Memory Mul'media Data / Sohware Seman'c Metadata Valua'on Explicit Knowledge PKM « BA » PKM PKM PKM PKM Common Prac8ce Problems in the social / personal KM dialec'c Can we improve the learning conversa'on? • Diﬀerences in natural languages, classiﬁca'ons, ontologies, folksonomic systems (accross individuals / networks / applica'ons) • Individuals par'cipate to several communi'es / networks • One community / network crosses several digital applica'ons • Several networks should be able to connect / share their memory • Do the current symbolic systems exploit fully the new distributed computa'onal power?
