Clueswhether

Clueswhether is a term used in linguistics and natural language processing to describe a set of cues in text or speech that signal the presence of a proposition that can be true or false, typically associated with embedded questions introduced by whether (or if in some varieties). The concept is employed to study how speakers convey uncertainty, belief, or evaluation, and how computational systems detect factual claims for tasks such as claim extraction and fact-checking.

Origin and usage: The word clueswhether is a portmanteau of clues and whether, emphasizing the role of cues in marking truth conditions within subordinate clauses. It appears primarily in contemporary NLP and discourse-analysis discussions rather than in traditional syntax textbooks. Researchers use the notion to categorize signals that indicate content-bearing clauses, as distinct from ordinary questions or hypothetical statements.

Characteristics: Clueswhether encompasses lexical signals (whether, if), modals (may, might), evidential verbs (show, indicate), hedges (perhaps, maybe), negation, and punctuation that together promote the interpretation of a sentence as asserting a claim rather than merely asking a question. Syntactic cues include the presence of a clause headed by whether in subordinate structure and its position within the sentence. In practice, these cues help annotate text for whether a clause expresses a factual proposition, a claim, or a stance.

Applications and limitations: In fact-checking, summarization, information extraction, and question-answering, clueswhether aids systems in identifying content that asserts truth values. Limitations include context-sensitivity, polysemy, cross-linguistic variation, and the lack of standardized definitions or datasets dedicated to the concept.
