Exapia categorises data in multiple ways

Humans typically view data from many different points of view and our recognition of meaning is made much more subtle by the way in which we categorise things in different ways simultaneouly. For instance, the phrase "childrens' books" is definitely about books, but for humans, the word 'childrens' conjures books which are illustrated. If no books are found which are classified as children's books, then it may still suggest illustrated books.

Exapia is capable of categorising data into many different 'taxonomies' or classification systems. This helps it to focus more precisely on really relevant items or, if no data is found from the obvious meaning of the query, it can find useful items by fetching those whose multiple-classification pattern is close to the pattern of the query.
