Abstract: Various embodiments are described herein that relate to communication systems that employ Natural Language Processing (NLP). More specifically, various embodiments relate to systems, methods, and interfaces for performing asynchronous speech act detection on text-based messages transmitted between used of a communication platform. Asynchronous speech act detection allows the content of the messages to be analyzed without interrupting the flow of communication. That is, the messages can be posted for viewing (e.g., to a chat room) and simultaneously transmitted to an NLP server for further analysis. The posted messages can subsequently be updated (e.g., by adding labels that are used for storing, searching, etc.).
