  1. 1. From Data Dirt Roads To Infocosm Invited Talk, 7th Intl. Conf. on Management of Data, Pune, India, Dec. 29, 1995. [Some parts of the talk emphasize issues and perspectives of particular interest to developing countries.] Amit Sheth Large Scale Distributed Information Systems Lab University of Georgia Special Thanks: Vipul Kashyap, Srilekha MudumbaiInfocosm (Amit Sheth) 1
  2. 2. Outline ³ Infrastructure computing and communication to support information society in the next century ³ State-of-the-art Internet, WWW, Electronic Commerce unique opportunities due to Network Computing ³ New Challenges in Information ManagementInfocosm (Amit Sheth) 2
  3. 3. Our Journey to the Information Society ³ Information (Data) Superhighway (aka Infobahn) material/physical object-- geography, distance* infrastructure not services or application* high cost of broadband fiber-optic networks promoted TV (not computer) as the user device computer has been found to be a better starting point promise of applications envisaged earlier have fizzled 500 channel TV, VOD and the interactive TV? What went wrong?Infocosm (Amit Sheth) * see also for related discussion: The Road Ahead, Bill Gates. 3
  4. 4. Journey and Destination ³ “The Information superhighway is an impoverished metaphor -- it describes only a means of transportation. We need a description of the destination, of the Infocosm.” [Ferguson] Glover Ferguson, Computer World, Vol. 1, Iss. 6, July 17 1995.Infocosm (Amit Sheth) 4
  5. 5. Destination Infocosm a society whose members (“organisms”) can have more effective decision making capability using information that is available whenever needed, at any place, and in (m)any form(s) [Sheth 93] a world where people will work, learn and play, unconstrained by time, place and form [Ferguson 95] Sheth and Kashyap, Information Brokering- A Key Challenge in the emerging Infocosm, December 1993. Glover Ferguson, Computer World, Vol. 1, Iss. 6, July 17 1995.Infocosm (Amit Sheth) 5
  6. 6. Related Themes ³ Telecosm (George Gilder) focus on communication and data need to add computing and information ³ Telepresence ³ “Information at Fingertips”*Infocosm (Amit Sheth) 6
  7. 7. Components Information Computing CommunicationInfocosm (Amit Sheth) 7
  8. 8. Computing and Communication ³ The last decade belonged to computing, PC is 120B$ business. ³ Next decade will belong to communication. ³ Future computing will be networked oriented (analogy of neural nets: “the intelligence will be in the network”). We will sell and use Information, not data. X Opportunity for Developing Countries!Infocosm (Amit Sheth) 8
  9. 9. Wireless communication • Stratospheric market estimates are norms, but prior expectations have exceeded • Estimates of wireless communication devices: 224M by the year 2000, 300M by the year 2002 • Growth rate of 40-50% => economy of scale • Tremendous number of alternatives • India and developing countries will have larger share of wireless than most expectInfocosm (Amit Sheth) 9

  37. 37. Focus on information ³ Exponential growth in the capability of computing (Moore’s law) and communication bandwidth is well documented. ³ Our ability to represent information and knowledge: from numbers and letters to objects and relationships, from syntax to semantics, from transactions to workflows, from data to information, ... has received less attention, is harder to address, and has lagged.Infocosm (Amit Sheth) 8
  38. 38. Data vs Information Data Information Set of facts Application of facts and knowledge of “when” to use facts Data Measurements about the real world Derivation from facts using cognitive obtained from human/machine sensors and perceptual processes Interoperability ==> transformation across Interoperability => transformation of different forms, representations and query knowledge to make it suitable for languages application of different facts in a different environment Data + Knowledge about Meaning of data = Information + Knowledge of when to apply it Information can be used for decision making based on dataInfocosm (Amit Sheth) 9
  39. 39. Technical Challenges in Global Information Systems Difficulties in information access: cosmic Easter egg hunt problem-- hard to locate and access pertinent problem information; write-only database problem -- easy to create, hard to maintain Scale: needle in the haystack problem vast amount of information; large number of autonomous sites Heterogeneity: tower of Babel problem Information represented in different ways Query expressiveness: the Pidgin problem query language not expressive enough to specify the user’s interest Information Overload: too much junk (less relevant) information on the networkInfocosm (Amit Sheth) 10
  40. 40. Some approaches .... User centered approach: menu-based browsing hypertext browsing Syntactic/structural approach: information retrieval, indexing techniques name and attribute-based search, pattern matching Descriptive (symbolic) semantics-based approach making design assumptions explicit capturing the semantics of the query Cognitive (sub-symbolic) semantics-based approach Pattern/Speech Recognition Algorithms Neural NetworksInfocosm (Amit Sheth) 1
  41. 41. Challenges with current techniques for Information Resource Discovery Unattractiveness of Navigation and Browsing: tend to give up if the number of links are more than 3 or 4 need to annotate links with contextual information in order to help reduce the “link- chasing” Scalability problems in Indexing information: cannot index all the information on the internet !! difficult to index heterogeneous but related information combining results obtained by using independent/ different indices Hard to maintain pre-determined relationships: file update might make some hyper-links meaningless !! hierarchical organizations might prove expensive to search if user specified criteria for search is different from criteria of organizationInfocosm (Amit Sheth) 2
  42. 42. Infocosm via InfoHarness and InfoQuilt ³ InfoHarness access, scale, heterogeneity ³ InfoQuilt query expressiveness, semantics correlation of heterogeneous media InfoHarness is a trademark of Bellcore. Adapt/X Harness is a commercial product based on the InfoHarness system (see (Amit Sheth) 3

List of Collections that man pages include this IHO Physical Data •Logical structuring of information space without restructuring, reformatting or relocating •Accessing information via logical units •Utilizing third party indexing tools to search for informationInfocosm (Amit Sheth) 6
  46. 46. Keyword-based AccessResults of the WAIS QUERY Let’s Look at the 2nd article.
  47. 47. We can use keywords to querythe WAIS collection, but we cannot provide the semantics “author”with the keyword “kilpatrick” Kilpatrick is not the author! He is referenced.
  48. 48. Attribute-based AccessAn attribute-basedaccess method allowsthe specification ofsemantics like “author”and “date”. The typedattribute “date” allowsdata access notsupportedby keyword basedmethods
  49. 49. The results will onlycontain those articlesauthored by Kilpatrickthat were posted afterJuly 1, 1995.Keyword-based and Attribute-based access are complementary

The round globe is a vast ... brain,instinct with intelligence!” [AI Gore’s Quotation of Nathaniel Hawthorne, 1851]Zooming is when you overcome your fears and trust the universe to make things right.You fly and float and hum and weave and sing. Opportunity knocks. Hello! I likeplaying with people who zoom. Win-win deals all the time. It’s cooool ..... On reallycool days I zoom. On reallllllly cooooooooool days I zooooooooom.

  66. 66. Partial Bibliography Besides the articles referred in the presentation, there is considerable information in popular and technical literature on the topics of information superhighway, metadata, electronic commerce and related topics. I suggest using any of the existing Web tools for a search (for example, most Internet-tools will return more than one hundred URLs for any of these topics). Because the list is too large, below is a partial list of research publications with which the speaker has been associated. These and other LSDIS publications can be obtained from A. Sheth and L.
