Data Files

keywords.xml (keywords and linked words)

This file contains a list of keywords (keyword) along with a list of the most commonly used words (word) that are paired with that keyword in a multi-keyword search.

For each keyword, a count shows the number of times it has been used as a search term.

For each of the paired words, a count shows the number of searches in which both terms have been used. The frequency value indicates the strength between that word and the parent keyword.

In the example below, for the keyword "depression" which has been used in 2,542 searches, the most commonly paired word is "great" (as in "The Great Depression") and there have been 99 searches that use both terms. The word "great" itself is infrequently used with "depression" (freq=5%) -- in total there have been 1,813 searches using the word "great", but only 99 of them also included "depression" (i.e. 99 / 1813 = 0.0546 or 5%). The word "great" is more commonly paired with words like "britain" and "war".

The word "postnatal" has a much stronger link to "depression" (freq=67%), as it has only been used in 133 searches (89 / 133 = 0.669). The words "natal" (as in "post-natal"), "manic", and "sadness" also have strong links to the word "depression".
