-Specialized opinion dictionary.

-Expert opinion dictionary

-Creative dictionary

-Point-of-view/Standpoint dictionary

If this is in reference to the author's definitions of words within his own texts, it would be called the following: Exegetic dictionary

"1. Exegetic dictionaries: they deal with the text of some author or many authors and are prepared in different ways. A dictionary f this type may cover a particular work of an author e.g. Padmaavata Kosa, of Jayasi, Maanasakosa of Tulasi, Dictionary of the Autobiography of Gorky. Such dictionaries also cover all the works of a particular author. e.g. Dictionary of Shakespeare, Tulasikosa, The Dictionary of Pushkin etc.,

This dictionary contains all the words available in the text or texts. All the meanings of a lexical unit are given with illustrations and the actual places of their occurrence. Sometimes the total number of the occurrences of the lexical unit are also given to show the frequency of the lexical unit. In some dictionaries only the first and the last occurrences are noted. They not only give the lexicographic definitions but also encyclopaedic information and include proper names also. These dictionaries provide guidance for understanding the special usages of the lexical units by different authors. They also help in knowing the new words used by writers as also the new meanings attached to the present lexical units. They are useful in preparation of the historical dictionary of a language. " (see first web source).

However, many scholarly articles make reference to something called "internal subjective dictionaries" which are related to your thought processes and the way in which you understand terms, whether it be the same as the actual definition in an objective dictionary or not (see second source).

Personally I think you could also say "Personal Subjective Dictionary" seeing as it pertains to his personal perceptions of the definitions, or even include his name, for example: Roger's Personal Subjective Dictionary just like we would do with "Merriam Webster" or "Oxford", etc.
