  1. The Needle in the eHaystack: A Broad Perspective of the navigation in the digital spaces of contents Gadi Ariav Info 2006

  2. outline • information and information behavior • information behavior orientation  DSS • the DSS imperative: • the design cycle • dialog, data, model • NeGeV personal TV environment as a DSS • an open list of research questions

  3. information some common myths… and their implications: • only “objective” is valuable  Web 2.0 • more is better  need driven • can be provided out of context  task dependent • there is relevant info for every need  complexity • ‘privatizing’ external info is easy  “what do people do to information?” (Case, 2002)

  4. basic concepts • data accumulation concepts: • key:eventcapturedata • organized around process and feedback • data usage / decision support concepts: • key: action decision information • organized around decision situation

  5. DSS design – overview • role • Process • Range • Depth • environment • Task Type • Access Pattern • structure • components • architecture • evaluation criteria • answers • reducing uncertainty • making sense

  6. ds implementation loop • …user with a decision task •  DSS design: • analysis, evaluation, construction •  a decision support system: • dialog, data and model management • user with a decision task*  …

  7. DSS structure – overview • model management • dialog management • User & tasks • data management • external data & neighboring IS

  8. dialog management • user interface… to infinitely varied users • dialog structure… to infinitely varied situations • unified interface… to infinitely varied resources

  9. data management • repositories of source-data… of infinitely varied types • meta data about the repositories • interrelated private and public data • unified staging… of infinitely varied external repositories

  10. model management • repositories of models… • of global search • of situational search of infinitely varied types • meta data about the repositories • integrated application of diverse models

  11. TV –the killer info appliance Source: Forrester

  12. “The Global Broadcast television industry is undergoing fundamental change that is rendering the network model obsolete” • “Today’s consumers are seeking content across an expanding array of transmission media, channels, interactive platforms and devices” • “Demand for content is exploding in all forms of media and this creates significant opportunities” • “Networks will offer content across variety of media channels and formats”

  14. NeGeV challenges • mass-customization • large-scale mass-customization • completely inadequate infrastructure: • narrow-cast on broadcast network • sophistication on cheap and weak STBs • cautious traditional incumbents

  15. NeGeV services • gaps: • dictated broadcast schedule • limited content selection by viewer • homogeneous viewers assumption • limited profile of viewers preferences • technological challenges: • content selection from vast depositories • identification and management of preferences • massive mass-customization of the above • cross-platform personalized viewing tracks • sharing of V-Environment characteristics

  16. NeGeV “front-end” research

  17. info seeking challenges • wrong focus of tools • behavioral assumptions • types of data: • (directly) codifiable vs. non-codifiable • qualitative specs • types of questions: • factual, inferential, causal, predictive

  18. info seeking measurement • tangible outcomes (?) • impact on information process: • personal efficiency, problem solving style • impact on information user: • perceived “usefulness” & “result comfort” • extent of structure • extent of insight & understanding

  19. …and a final thought

  20. recap • information and information behavior • information behavior orientation  DSS • the DSS imperative: • the design cycle • dialog, data, model • NeGeV personal TV environment as a DSS • an open list of research questions
