Information Retrieval Activities
Selecting a collection– Talked about last class– Lists, overviews, wizards, automatic selection
Submitting a request– Balancing expressiveness and usability– Command line, graphical, and NL interfaces
Examining the response– Comprehension– Contextual displays

Evaluating Retrieval ResultsSelecting among returned documents
– Requires partial understanding of documents without looking at whole document
To provide understanding of documents:– Show relations to query terms– Show in collection overviews– Provide descriptive metadata– Indicate document structure– Indicate the hyperlink structure– Indicate relations between returned
documents
![Page 4: Interfaces for Retrieval Results](https://reader035.vdocuments.mx/reader035/viewer/2022062814/568167f0550346895ddd615d/html5/thumbnails/4.jpg)
Document SurrogatesResulting documents are presented by
partial information about document– Important metadata (title, date, source)– Selected chunks of document– Thumbnail images of documents
Some systems provide short and long document surrogates.
Normally, clicking on a surrogate causes the document to be displayed.

Document Relation to Query
Simple ways to indicate relation:– Select snippet with query terms– Highlight query terms in document
display (thumbnail or whole)
– Scroll to first occurrence of query term

Popout Prism
![Page 10: Interfaces for Retrieval Results](https://reader035.vdocuments.mx/reader035/viewer/2022062814/568167f0550346895ddd615d/html5/thumbnails/10.jpg)
Keyword in Context (KWIC)KWIC document surrogates
– Phrases and sentences with query terms are extracted
– These snippets are presented along with metadata
Design issues– Deciding how many and which occurrences
of keywords to show– Use query term weights, if any– Evidence indicates selecting text segments
with largest number of query terms that appear near beginning of document
![Page 11: Interfaces for Retrieval Results](https://reader035.vdocuments.mx/reader035/viewer/2022062814/568167f0550346895ddd615d/html5/thumbnails/11.jpg)
TileBars
TileBars is a compact visualization of documents’ relation to query terms.
Document surrogate is a rectangular bar divided into a matrix/table
– Rows correspond to query facets– Columns are sections of document– Darkness in each row/column position
indicates the occurrence of that facet in that portion of the document.

SeeSoftVisualization where each line of
document is visualized as line in graphical column
Color indicates characteristics of the line.
Originally developed to help understand program code
Applied to document analysis and text retrieval

Relative Query Term Relations
Prior set of systems present individual documents and their relation to query terms
To present a larger number of results– Visually represent sets of documents– Indicate sets’ relations to query terms
Examples– InfoCrystal– VIBE
![Page 16: Interfaces for Retrieval Results](https://reader035.vdocuments.mx/reader035/viewer/2022062814/568167f0550346895ddd615d/html5/thumbnails/16.jpg)

SuperbookUses a table of contents to indicate where
query terms appear– Requires document structure
![Page 19: Interfaces for Retrieval Results](https://reader035.vdocuments.mx/reader035/viewer/2022062814/568167f0550346895ddd615d/html5/thumbnails/19.jpg)

Categories for Retrieval Results
Present results in groups based on some categorization
– Categories can be based on metadata– Categories can
be inferred– Categories can
be chosen basedon query type(DynaCat)
![Page 21: Interfaces for Retrieval Results](https://reader035.vdocuments.mx/reader035/viewer/2022062814/568167f0550346895ddd615d/html5/thumbnails/21.jpg)

Hyperlinks for Retrieval Results
Present navigational links between retrieved documents
– Relies on links between documents– Most often used for searching a single
web site (or similar repository)
Examples– Cha-Cha– Mapuccino
![Page 23: Interfaces for Retrieval Results](https://reader035.vdocuments.mx/reader035/viewer/2022062814/568167f0550346895ddd615d/html5/thumbnails/23.jpg)

Table Views for Retrieval Results
Category and link views present only one type of interdocument relation
Documents have many different potential relationsTabular views can provide an overview of a set of
relations– Each row is a document– Each column is an attribute (metadata field or other)– Content of table indicates values and relations
between valuesExamples
– Envision– TableLens

SummaryUsers must partly understand retrieval results to
select which to view.Techniques:
– Highlighting and scrolling indications of relations to search terms (snippets, Google cache, Popout Prism)
– Set-based views in relation to search terms (InfoCrystal, VIBE)
– Visualization of search terms in sections (TileBars, SeeSoft, SuperBook)
– Categorization of results (DynaCat, clusty.com)– Hyperlinks between results (Cha-Cha, Mapuccino)– Table views of results (Envision, TableLens)
