Coloring search results based on score?

Hi all,


Interesting question: is it possible to color search results in a web-page based on their score? e.g. most relevant results in green, and then different shades through orange, yellow, red and then white.


Theoretically, one could take the highest score and color based on proximity / distribution, but the highest score can be invalid in itself.


I could bring in a hardcoded cutoff point, where results are not considered relevant and not color any results if the highest score doesn't go above that threshold (e.g. score = 1.0), but then again - complex queries can yield relevant results with low scores.


So my question is: has anyone ever tackled this issue, and is this even doable?


Thanks in advance!


Itamar.

What you describe reminds me of a special case of a more general
visualization technique called Tilebars. Tilebars are an N x M
histogram, where N rows correspond to N query terms (or clauses), and
M columns represent buckets of score contributions distributed over
the sections of the document. Each cell is then colored according to
the portion of score that it contains.

The coloring schema may be non-linear, and the document division into
chunks may not be linear either.

You can then collapse Tilebars if you wish in one or both dimensions,
e.g.:

* N x 1 represents relative score contributions from each query term
* 1 x M represents the distribution of score contributions along the
length of document
* 1 x 1 represents the relative score of all clauses for the whole
document, relative to other documents (the difference is in coloring)
