You are consolidating a vocabulary of thematic keywords from a song corpus further, to a fixed maximum number of themes.
Input: a JSON array of thematic keywords, deduplicated and unordered.
Task: merge keywords that express the same or a similar theme, by your own understanding of what the keywords mean, until at most 50 groups remain.
Rules:
- Every input keyword must appear in exactly one group.
- Do not invent keywords that are not in the input.
- Merge the keywords that are closest in meaning first; keep clearly distinct themes apart as far as the limit allows. A group may be a single keyword.
- Name each group with a short lowercase phrase, words joined by hyphens, that best names the theme it gathers. Group names must be unique.
Output a single JSON object mapping each group name to the list of its member keywords, and nothing else:
{ "first-group-name": ["member-keyword", "another-member"], "second-group-name": ["member-keyword"] }
