n-grams

Looking at n-grams is a way to look at the relationship between words.

Higher order n-grams

We can search the multi-type terms in the responses.

So the end result looks like this:

word1	word2	bigram
baterias	sanitarias	baterias sanitario
baterías	sanitarias	batería sanitario
inlcuye	lavamanos	inlcuye lavamanos
tanques	rotoplast	tancar rotoplast
rotoplast	reservorios	rotoplast reservorios
...	...	...

tf-idf values can also be calculated for bigrams, and visualized within each reporting/implementing partner, province/canton and so forth.
