  • Envisioning Modern Discovery, Communication
    Collaboration
  • Discovery
  • Communication
  • Collaboration

3
The Work World Without the Web
4
Pre-WWW Work EnvironmentDiscovery,
Communication, Collaboration
  • Meet with someone face-to-face, ask them a
    question (if you can catch them when theyre in)
  • Library - travel there and physically search
  • Write a letter, put it in an envelope, mail it
  • Phone
  • Fax
  • Travel to meetings
  • Networking meant Lets have lunch sometime!

5
Pre-WWW Work EnvironmentDiscovery,
Communication, Collaboration
  • Downsides
  • Time-consuming
  • Lots of travel required
  • Slow physical delivery 2-5 days via USPS
  • Inefficient, difficult work physical search
  • Expensive required extra costs
  • Sometimes travel expenses were misused for fun
  • Upsides
  • Social contact relationships
  • Rich human-to-human communication

6
Envisioning Modern Discovery, Communication,
Collaboration
7
The Vision
  • Discovery
  • Low cost/no effort
  • Very flexible
  • Search and find by content or terms
  • Semantic search by context or meaning
  • Document-to-Document Linkages
  • One-way
  • Two-way
  • Communication/Collaboration
  • Minimal travel low cost
  • Maximum flexibility and functionality
  • If traveling, you can connect to it and use it
    wherever you are

8
The Visionaries
  • Vannevar Bush - 1945
  • vision of machines for information storage and
    retrieval, research dissemination
  • Project Xanadu - 1960s - present
  • two-way inter-linkages between documents
  • relationships between information in multiple
    documents
  • Tim Berners-Lee - 1989
  • WWW proposal to CERN
  • Hypertext Transfer Protocol (http) a simpler
    system to get and put documents for storage
    and retrieval
  • The Semantic Web a next generation WWW he is
    developing now

9
Discovery
10
Discovery Via the Web
  • Discovery is the process of finding stuff of
    interest or of use
  • The Resource
  • WWW - is a vast collection of interconnected
    pages of information that are stored (or
    generated from programs and databases) on Web
    server computers around the world.
  • The Problem
  • All of the information in these pages is
    unstructured or takes a variety of structures.
  • There is no perfect index or card catalog for
    it.

11
Supporting DiscoveryVia the Web
  • Storing retrieving information in WWW documents
  • Hypertext
  • save information in text file (.html)
  • Hyperlinks
  • link to related resources of which you are aware
  • Upload text file (.html) to a Web Site
  • A directory on a computer
  • A URL
  • Client / server architecture
  • WWW server software runs 7/24/365 on a server
    computer, listens to Internet port, waiting for
    a get or put message from another computer
    (the client browser)

12
Supporting DiscoveryWWW Technologies
  • Downloading software and files
  • FTP file transfer protocol
  • Anonymous FTP used to be the way to find stuff
    people stored for public use
  • Gopher (U of Minnesota)
  • primitive, not enough acorns of info., basically
    dead
  • Web Browsers (U of Illinois)
  • HTTP get or put using the URL (uniform
    resource locator)
  • FTP, TELNET and other programs right from within
    browser
  • Search engines
  • Google (www.google.com)
  • Meta-Search engines
  • search across WWW search engines, EX Dogpile
    (www.dogpile.com)
  • BC Database Meta-Search Engine (metalib.bc.edu)

Internet-based Software AgentsDiscovery About
Personal Patterns
  • Software that rides on top of and monitors other
    software applications
  • E-mail program
  • WWW browser
  • WWW sites
  • Collects data on what you do (or other info.)
  • Determines patterns in your behavior (or across
    sites, etc.)
  • Generalizes about your past behavior to predict
    future behavior
  • Examples
  • E-mail agents
  • Web-browsing-assisting agents
  • Intelligent indexing agents

17
Internet-based Software Agents
18
Internet-based Software AgentsDiscovery of
Customer Activities
  • Corporate technologies
  • Ex Jupiter MediaMetrix
  • Uses a software agent installed on consumer
    desktop computers to monitor the Web browser
    activities in 10,000 consumer households
  • Sells this data, and research based on the data,
    to corporate marketing researchers
  • Ex NetRatings/AC Nielsens eRatings.com
  • Use systems similar to above

19
Discovery Internet-based Data Mining
  • Resource discovery
  • End User mine information about interests,
    companies, etc.
  • Company mine information about users, customers,
    WWW site operations, etc.
  • Information extraction
  • Many companies now use WWW spiders to monitor
    Websites where contract RFPs are posted
  • Generalization
  • Company predicts future customer behavior

20
DiscoveryInternet-based Data Mining
  • Ex FBI
  • Carnivore captures suspects emails, processes
    them to identify evidence of crime
  • Ex CIA
  • Fluent scours foreign WWW sites, translates
    text, displays it in English for CIA agents
  • Oasis listens to worldwide television
    broadcasts and radio broadcasts (now often
    streamed over the WWW), transcribes content and
    generates reports for CIA analysts

21
Communication
22
Communication
  • Communication is an interpersonal process of
    sending and receiving symbols with messages
    attached to them.
  • Verbal words (symbols alphabet and
    numbers messages meaning of words)
  • Nonverbal smiles ( symbol message Im
    happy), sweating on the brow, pulsing veins on
    the neck, wringing of hands, spatial relationship
    to others

24
CommunicationProblems with IT for Communication
  • Some communication methods are better at
    communicating verbal messages, others are better
    at communicating nonverbal messages
  • Ideally, we would like to convey both verbal and
    nonverbal symbols in a way that their messages
    are unambiguous
  • But, unambiguous messages are difficult to convey
    even in the non-digital world

25
Supporting CommunicationFactors Determining the
Uses of Information Technology
  • Important Factors in Communication IT
  • Participants
  • of participants
  • Communication styles most comfortable with
  • Nature of sources and destinations
  • Location
  • Time
  • Synchronous (real-time) communication
  • Asynchronous (different times) communication
  • Media

26
Supporting CommunicationWWW Technologies
  • Newsgroups
  • Mailing lists and electronic bulletin boards
  • Electronic mail - e-mail
  • Internet and intranet (POP, IMAP)
  • SMS messaging on WAP cellphones (i-Mode text
    messages)
  • Blackberry email clients (and similar competing
    devices)
  • Chat programs/Instant Messaging
  • Web-site Java applets for chatting
  • Internet Relay Chat (IRC)
  • ICQ (I seek you) even includes SMS messaging
    now
  • AOL IM, MSN Messenger, etc.
  • Video Chat
  • CUSeeMe and similar applications

Asynchronous
Synchronous
27
Supporting CommunicationWWW Technologies
  • Peer-to-Peer (P2P)
  • Systems that directly connect from two to a large
    number of small computer systems
  • Facilitate file sharing (e.g., Napster, Gnutella,
    BearShare), application sharing (e.g., Groove)
  • Electronic Voice Communication
  • Interactive Voice Recognition (IVR)
  • Voice Annotation
  • Automated Attendant
  • Voice Mail
  • Audiotext

    experiences.

55
Distance Learning (DL)
  • Over 2000 educational institutions offer distance
    learning classes
  • Over 300 distance learning degree programs

56
Distance Learning (DL)
