The data-dictionary tag has the following description:
A data dictionary, or metadata repository, as defined in the IBM Dictionary of Computing, is a "centralized repository of information about data such as meaning, relationships to other data, origin, usage, and format."
The tag is used for 5 questions that are all related to a language 'dictionary' (i.e German-English translation). I'd suggest replacing data-dictionary with dictionary for these 5 questions, and then removing the data-dictionary tag.
