To help me understand what you're looking for, could you please provide more context? For example:
* What specific subfield of KPUP are you interested in? (e.g., information retrieval, natural language processing, knowledge representation)
* What is the specific scenario where you are using "recalling in"? (e.g., searching for a specific piece of information, summarizing a text, answering a question)
Once I have more context, I can provide a more relevant and helpful answer.
