Concept Occurrences

An occurrence gives the number of times a selected concept is used in K10plus database. Co-occurrences give the number for combination of concepts so they can be used as mapping recommendations. This service allows to query (co-)occurrences of selected vocabularies (RVK, BK, DDC...) from K10plus database. The results are partly based on a database snapshot.
