  Keyword extraction is one of the core tasks in natural language processing.
Classic extraction models are notorious for having a short attention span which
make it hard for them to conclude relational connections among the words and
sentences that are far from each other. This, in turn, makes their usage
prohibitive for generating keywords that are inferred from the context of the
whole text. In this paper, we explore using Large Language Models (LLMs) in
generating keywords for items that are inferred from the items textual
metadata. Our modeling framework includes several stages to fine grain the
results by avoiding outputting keywords that are non informative or sensitive
and reduce hallucinations common in LLM. We call our LLM-based framework
Theme-Aware Keyword Extraction (LLM TAKE). We propose two variations of
framework for generating extractive and abstractive themes for products in an E
commerce setting. We perform an extensive set of experiments on three real data
sets and show that our modeling framework can enhance accuracy based and
diversity based metrics when compared with benchmark models.
