Trends in Explainable AI (XAI) Literature

I searched for the following keywords in a SemanticScholar query and filter them using exact-match using papers' title abstract. This set of keywords is actually pretty conservative (initially I started with a bigger list), but even with this conservative set, 1-keyword-match filtering unfortunately resulted in many non-XAI papers being retrieved for various reasons -- so I only include papers match 2 unique keywords or more. A random sample of 100 papers yielded 99% precision with a manual check (one paper mentioned keywords in the abstract simply as motivation for adjacent research). The keyword-based search retrieved 3101 papers. Then searched for them by title using the SemanticScholar API with fuzzy matching.
