Keyword Analysis
Keyword analysis consists of creating a keyword summary report, a keyword usage report, and a keyword map.

Create a Keyword Summary Report
The Keyword Summary Report provides the following benefits. (see example keyword summary report below)

• Presents all or a selected part of your coding definitions.
• Helps to describe and share coding sets among members of your group.
• Helps you and your group to work on code definition consensus and inter-rater reliability.

Follow the steps below to create a keyword summary report for the entire database of for a specific keyword group.

• To create the Keyword Summary Report for the entire database
1. Right-click on the Keyword Root node in the Data Tree.
2. Click on Keyword Summary Report.
3. The Keyword Summary Report contains:
   • All Keyword Groups in the Transana Database.
   • All Keywords in each group with their definitions.
• To create the Keyword Summary Report for a specific Keyword Group
1. Right-click on the Keyword Root node in the Data Tree.
2. Click on Keyword Summary Report.
3. The Keyword Summary Report contains:
   • All Keywords in the specified Keyword Group with their definitions.

Keyword Usage Report
The keyword usage report provides three options for creating reports (see example below).

• Collection Keyword Usage Report:
  • Produces a list of keywords for all clips in a collection.
  • Summarizes the number of times each keyword appears in the collection.
• Episode Keyword Usage Report lists keywords for all clips created from the episode.
• Series Keyword Usage Report lists keywords for all episodes in the series.

Generate a Keyword Usage Report
To generate a keyword usage report, follow the steps below.

1. Right-click the name of a collection (or an episode, or a series) in the database tree.
2. Choose Keyword Usage Report from the pop-up menu.

Use All Three Versions of The Keyword Usage Report
The Keyword Usage Report can be created three ways. The following three different versions of the report, while subtle, have important analytic implications.

• Create a Keyword Usage Report from a Series
  • The report will list all Episodes within the Series.
  • The report will show all Keywords assigned to those Episodes.
• Create a Keyword Usage Report from an Episode
  • The report lists all Clips created from that Episode, regardless of Collection.
  • The report shows all the Keywords assigned to those Clips.
  • The report allows you to review all coding applied to a particular source video.
  • The report exists without respect to the analytic structure of the Collections where the Clips are.
• Create a Keyword Usage Report from a Collection
  • The report lists all Clips in that Collection regardless of what Episode they came from.
  • The report lists all the Keywords assigned to them and allows you to:
    • Review the coding applied to a set of Clips in a Collection
    • Review the coding to verify analytic reason for the Collection.
    • Review the inclusion of the Clips in the Collection, regardless of the original source of those Clips.

Contrast a Keyword Usage Report from an Episode vs. from a Collection
The difference between the episode keyword usage report and the collection keyword usage report is as follows:

• The Episode Keyword Usage Report
  • Looks at how source videos have been divided up analytically.
  • Provides analytic categorization implemented by distribution in Collections.
  • Provides coding that has been applied to the Clips through the assignment of Keywords.
  • Provides a "top-down" look at your data.
• The Collection Keyword Usage Report
  • Looks at portions of video from diverse sources that have been grouped together for analytic reasons.
  • Provides coding that has been applied to them through the assignment of Keywords.
  • Provides a "bottom-up" view of your data.

Keyword Map
Keyword maps have several uses to help you analyze your data.

• Use the Keyword Map to analyze keyword use for an episode.
• The Keyword Map shows how keywords have been applied to clips from that episode.
• Each color represents a different clip.
• The presence of the same keyword at the same location in different clips is not represented.
• The clip that is processed last in assembling this report will be the only one shown, when there is an overlap.

Generate a Keyword Map
You can generate a keyword map by following the steps below.

1. Right-click on the name of an episode in the database tree.
2. Choose Keyword Map from the pop-up menu.

Keyword Map Example

Colored Bands in the Keyword Map
The colored bands in the keyword map have the following meanings:

• Show the start and stop points of a Clip along the horizontal timeline of the Episode.
• Show where a keyword, along the vertical axis, has been applied.
• Multiple bands of the same color at the same point in the episode's time line:
  • Indicate a single clip with multiple keywords.

Use Keyword Map Options
You can save and print from the keyword map options.

• Use File > Save As to save a copy of the Keyword Map in JPEG format.
  • The JPEG image:
    • Will have the same width as the Keyword Map window on the screen.
    • Will have at least the same height as the Keyword Map window on the screen.
    • You may need to resize the window prior to saving your image.
    • Experimentation may be required to get the exact image size and proportions.
• Use File > Print Preview and File > Print to print a copy of the Keyword Map.
  • Dimensions of the window on the screen affect the overall shape of the printout.
  • Experimentation may be required to get the exact image size and proportions.

Keyword Timeline Bands - A Known Issue
Currently, the Keyword Map report has one major flaw with Keyword Timeline Bands.

• The Keyword/Timeline bands are drawn opaquely, overwriting previous band information.
• If a keyword is applied to more than one clip with overlapping time segments:
  • Only the last clip will be visually apparent.
  • If multiple clips share the same keyword / timeline space, there is no way to see that from the report.
