GeoJSON documents have become important sources of information over the Web, because
they describe geographical information layers. Supposing to have such documents stored in
some JSON store, the problem of querying them in a flexible and easy way arises. In this
paper, we propose a soft-querying model to easily express queries on features (ie, data
items) within GeoJSON documents, based on linguistic predicates. These are fuzzy
predicates that evaluate the membership degree to fuzzy sets; this way, imprecise conditions …
