Chapter 14
Information Search and Visualization
Activity
Objectives:
- Apply
the five-phase framework to clarify user interfaces for textual search
- Understand
textual search query
- Compare
data search queries through clustering to traditional data searches
performed by search engines such as Google
Directions:
- In
groups of 2 or 3, complete the following activity, refer to your textbook
p. 567 if needed.
- You
have 50 minutes to complete the activity.
- Write
up your results for grading. You
will present your results the next class period.

- The
link above is the Vivísimo
search engine called Clusty.
- According
to the five-phase framework to clarify user interfaces for textual search
(p. 567), Vivísimo does
a better job in grouping your searches into meaningful categories than
Google.
- To
prove or disprove the above statement, perform the following tasks:
- Access
the site.
- Initiate
a search: i.e. “Jobs in Maryland”
or any search you desire.
- In
the result page give an example of each of the following items:
Formulation
- The
engine provided access to the appropriate source in libraries and
collections
- Its
use of fields for limiting the
source
- How
it recognizes phrases to allow
entry of names
- How
it permits variants to allow
relaxation of search constraints (i.e. abbreviations)
- Control
the size of the result set
Initiation of action
·
Example of explicit
actions initiated by buttons with consistent labels
·
Example of Implicit
actions initiated by changes to the formulation phrase (make your search
more precise)
Review of results
·
Example of an explanatory message
·
Example on how you can manipulate visualization
·
Example on how you can adjust the size of the
results
·
Can you change the sequencing: i.e. try
alphabetical
·
Give an example of a different cluster by
changing the attribute value
Refinement
·
Example of a meaningful message that guided your
search in the refinement stage
·
Example of changing the search parameters
·
Example of a feedback you got on your query. How
relevant was it?
Use
·
Can you save your settings for other searches?
Give an example
·
Compare the above to the same search using Google
