TL;DR

This paper introduces an unsupervised framework to identify recurring surface question motifs and group them by latent rhetorical role using answer similarity in UK Parliament question sessions. It reveals that opposition MPs ask more aggressive, critical questions, while older MPs—especially in government—tend toward confrontational questioning, suggesting a 'less to lose' career trajectory effect.

ABSTRACT

Questions play a prominent role in social interactions, performing rhetorical functions that go beyond that of simple informational exchange. The surface form of a question can signal the intention and background of the person asking it, as well as the nature of their relation with the interlocutor. While the informational nature of questions has been extensively examined in the context of question-answering applications, their rhetorical aspects have been largely understudied. In this work we introduce an unsupervised methodology for extracting surface motifs that recur in questions, and for grouping them according to their latent rhetorical role. By applying this framework to the setting of question sessions in the UK parliament, we show that the resulting typology encodes key aspects of the political discourse---such as the bifurcation in questioning behavior between government and opposition parties---and reveals new insights into the effects of a legislator's tenure and political career ambitions.

Motivation & Objective

• To develop an unsupervised method for identifying recurring surface question motifs and grouping them by rhetorical function in political discourse.
• To investigate how rhetorical question types in parliamentary question periods reflect political dynamics, including partisan differences and career stage effects.
• To validate the induced typology against expert-coded categories from political science literature and demonstrate its predictive power.
• To explore how a legislator’s tenure and career ambitions shape their questioning behavior, particularly in relation to aggression and rhetorical strategy.

Proposed method

• Extract recurring lexico-syntactic question motifs from a newly released dataset of UK House of Commons question periods.
• Construct a latent question-answer space by modeling similarity in answers to group question motifs with comparable rhetorical functions.
• Use unsupervised clustering on the latent space to identify distinct rhetorical question types without prior labeling.
• Operationalize rhetorical role via the type of answer a question elicits, assuming similar answers imply similar rhetorical intent.
• Apply the framework to parliamentary discourse to identify patterns across party affiliation and legislative tenure.
• Validate the typology by comparing it to expert-coded question categories from prior political science research.

Experimental results

Research questions

• RQ1 How can recurring surface question forms be automatically grouped into meaningful rhetorical categories in political discourse?
• RQ2 To what extent do rhetorical question types in UK Parliament differ between government and opposition parties?
• RQ3 How does a legislator’s career stage—measured by tenure—predict their choice of rhetorical question types?
• RQ4 Do older MPs, particularly those with limited promotion prospects, exhibit more aggressive questioning behavior than younger colleagues?
• RQ5 Can the rhetorical function of questions reveal strategic signaling behavior related to political ambition?

Key findings

• The framework successfully identifies a range of rhetorical question types, from factual queries to pointed criticisms disguised as questions, with strong alignment to expert-coded categories from political science literature.
• Opposition MPs ask significantly more aggressive and condemnatory questions than government MPs, who favor friendlier, less confrontational forms.
• Older government MPs exhibit a higher propensity for aggressive questioning, especially toward their own ministers, supporting the 'less to lose' hypothesis.
• Younger opposition MPs contribute disproportionately more condemnatory questions than older counterparts, who favor concede/accept types, suggesting strategic signaling for future promotion.
• The tenure effect on questioning behavior is robust even after macro-averaging across MPs, indicating individual behavioral shifts over time rather than skew from a few prolific users.
• The study demonstrates that rhetorical question types encode key political dynamics, including party polarization and career-driven strategic behavior in parliamentary discourse.
