What do 'bands of recency' charts show?
Time segment charts on this site indicate bands of recency, comparing two sets of data over time:
- articles count (inner ring)
- total usage of a term (outer ring)
In each case, these so-called 'donut' charts display proportions of discussion over time:
- green segments indicate the proportions of articles / total usage less than 1 year old
- amber segments indicate the proportions of articles / total usage between 1 and 3 years old
- red segments indicate the proportions of articles / total usage more than 3 years old
As illustrated below, our automated tagging system produces a bands of recency chart for 'rdf':
- green segments indicate relatively few discussions of 'rdf' less than 1 year old (4.26% articles / 2.71% total usage)
- amber segments indicate some more discussions to 'rdf' are between 1 and 3 years old (12.77% articles / 11.06% total usage)
- red segments indicate most references to 'rdf' are more than 3 years old (82.98% articles / 86.23% total usage)
With these charts showing relative proportions of discussion over time, patterns can be interpreted as general indications of a topic's aging vs recency across all sources monitored.
