Some tags should not be displayed at all (aka removed), others should be merged. Eg:
Hibernate OGM, OGM -> Hibernate OGM
JBoss Tools Eclipse, JBoss Tools -> JBoss Tools
Basically there are two approaches. Either do the removal/merging of tags as part of the importing process or add something to the awestruct page (some helper function) which can be called from the code rendering the tags. The configuration of tags could for example be in some sort of YAML file, listing allowed tags and synonyms.
