Introduction
  • Propose an Interface design for information
    exploration
  • Example A user needs to write a term paper for a
    class on Greek art. He will consider his task
    successfully completed if he can find a good
    topic and a collection of resources on that
    topic.
  • Users look for new information within a defined
    conceptual area
  • Graphical user interface, design of icons for the
    Star interface
  • Three characteristics of information exploration
  • Accumulating a collection of references helps the
    user to accomplish the end goal of discovering
    new information.
  • Users often need to consult multiple,
    heterogeneous sources.
  • The evolution of a users interests depends upon
    the changing characteristics of the information
    context

Information Context
  • Importance of information context to information
    exploration
  • Each new piece of information users encounter
    gives them new ideas and directions to follow
    and, consequently, a new conception of the query.
  • From search session to search session, searchers
    used data from their present situation to
    determine where to go next
  • People move from one information patch to another
  • Approximate a users information context by
    current collection of references (?? return ???)
  • Model or approximate information context so that
    users can
  • examine the current context
  • progress from one context to the next

SenseMaker Usage Scenario (I)
  • Initial Search
  • Search query and maximum waiting time
  • Query for Java interface
  • Viewing the collection
  • Unified view results with identical URL values
    are bundled together
  • URL-based View (Figure 1)
  • Expand the collection
  • More results that both satisfy the original query
    and having URLs from sun.com and javasoft.com
    (Figure 2)
  • Query-By-Example ?Can search from more
    information sources
  • Duplicate Detection delete identical titles
    (Figure 3)

5
SenseMaker Usage Scenario (II)
  • Limiting the Collection ????????Criterion???
  • Viewing the Collection Bundle together results
    with similar title values (title-based view)
  • Expanding the collection again
  • New keyword query Java security
  • Old and new search results are shown together

Evolution of Interests
  • Information explorers move from one area of
    interest to another based upon what they find
    along the way.
  • The current information context, approximated in
    this case by the current collection of
    information references, plays a large role in
    determining what the user will do next.
  • Developing an understanding of the current
    context is not simple.

9
Examining the Information Context
  • Search??Return?????????Better Overview
  • Enabling users to get better overviews of their
    accumulated references is one of the SenseMaker
    design goals.
  • Sensemaker Approach
  • Bundling and merging identical results
  • View Types dimensions of URL, author, subject,
    title
  • Should be flexible (according to user needs and
    search services)
  • Bundling bundling criteria depend on view types
  • URL Type bundling
  • Geographic location bundling
  • Duplicate Detection Should be flexible

Progressing from One Information Context to the
Next (I)
  • Expand actions
  • Expand by issuing a query-by-example
  • The results to be added to the collection must
    both satisfy the original query and share the
    defining characteristic of the example bundles
    (p4 ???)
  • The results to be added to the collection are no
    longer required to satisfy the original query
    (?????????)
  • ? RDBMSs QBE IRs Relevance Feedback???
  • Expand by asking for related references
  • Add results if they stand in a defined relation
    to the given examples
  • Authors colleagues, similar topics, cited topics
  • Expand by issuing a new or refined query
  • Add to current set of results
  • Suggest for refining like synonyms

11
Progressing from One Information Context to the
Next (II)
  • Expand actions
  • Expand by enlarging the scope of the previous
    query
  • Limit actions
  • Limit by focusing on selections
  • Limits the collection to the sun.com and
    javasoft.com bundles
  • Limit by issuing a query over the current
    collection
  • Limit a collection to just those results that are
    post-1995
  • Replace actions the current collection is erased
    and a new collection is substituted in its place
  • Issue a brand new query
  • Variations on all of the expand action
    possibilities could be used as the means to
    produce a new collection (new results are not
    added to the old collection)
