It's High Time: A Survey of Temporal Question Answering
Pith reviewed 2026-05-19 12:59 UTC · model grok-4.3
The pith
A tripartite taxonomy of corpus temporality, question temporality, and model capabilities unifies the temporal question answering literature.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The paper establishes a unified perspective that captures the interaction between corpus temporality, question temporality, and model capabilities, enabling a systematic comparison of datasets, tasks, and approaches across the temporal question answering literature.
What carries the argument
The tripartite taxonomy consisting of corpus temporality, question temporality, and model capabilities, which serves as the organizing lens for comparing existing work.
If this is right
- Datasets and approaches can be compared systematically along the three temporality dimensions.
- Progress in transformer-based and LLM methods for temporal reasoning can be situated relative to specific combinations of corpus, question, and model temporality.
- Challenges such as temporal intent detection, time normalization, event ordering, and reasoning over evolving facts receive a shared analytical structure.
- Benchmark design and evaluation strategies can be assessed for how well they probe each temporality type.
Where Pith is reading between the lines
- The taxonomy may help identify gaps where new datasets should target underrepresented combinations of the three temporality types.
- Model development could prioritize testing performance when corpus temporality and question temporality are deliberately mismatched.
- The same lens might be applied to related time-sensitive tasks such as temporal summarization or event timeline construction.
Load-bearing premise
The tripartite taxonomy is comprehensive and non-overlapping enough to classify the entire body of temporal question answering research without significant omissions or forced fits.
What would settle it
A new temporal question answering paper or method that cannot be placed within the categories of corpus temporality, question temporality, or model capabilities would challenge the taxonomy's claimed coverage.

read the original abstract
Time plays a critical role in how information is generated, retrieved, and interpreted. In this survey, we provide a comprehensive overview of Temporal Question Answering (TQA), a research area that focuses on answering questions involving temporal constraints or context. As time-stamped content from sources like news articles, web archives, and knowledge bases continues to grow, TQA systems must address challenges such as detecting temporal intent, normalizing time expressions, ordering events, and reasoning over evolving or ambiguous facts. We organize existing work through a unified perspective that captures the interaction between corpus temporality, question temporality, and model capabilities, enabling a systematic comparison of datasets, tasks, and approaches. We review recent advances in TQA enabled by neural architectures, especially transformer-based models and Large Language Models (LLMs), highlighting progress in temporal language modeling, retrieval-augmented generation (RAG), and temporal reasoning. We also discuss benchmark datasets and evaluation strategies designed to test temporal robustness,

Referee Report
Summary. The paper surveys Temporal Question Answering (TQA), a subfield addressing questions with temporal constraints or context from time-stamped sources such as news and knowledge bases. It organizes the literature via a tripartite taxonomy of corpus temporality, question temporality, and model capabilities to enable systematic comparison of datasets, tasks, and approaches. The survey reviews neural and LLM-based advances in temporal language modeling, retrieval-augmented generation, and temporal reasoning, along with benchmarks and evaluation strategies for temporal robustness.
Significance. If the taxonomy proves comprehensive and non-overlapping, the survey would meaningfully structure a growing research area, facilitating comparisons across TQA work and highlighting gaps in temporal robustness for transformers and LLMs. As a literature survey, its value lies in coverage and organization rather than novel derivations; the absence of post-hoc exclusions or self-referential claims supports its utility for researchers entering or advancing the field.
minor comments (3)
- [Abstract] The abstract ends abruptly at 'temporal robustness,'; complete the sentence to ensure the overview of evaluation strategies is fully stated.
- [§3] §3 (Taxonomy section): provide explicit decision criteria or boundary examples showing how the three categories remain non-overlapping when a single paper addresses both corpus and question temporality simultaneously.
- [Dataset comparison table] Table 1 or equivalent dataset overview: include publication years for all cited datasets to allow readers to assess recency of coverage.
Simulated Author's Rebuttal
We thank the referee for their positive evaluation of our survey on Temporal Question Answering. We appreciate the recommendation for minor revision and note that no specific major comments were raised in the report. We will incorporate any minor suggestions during the revision process to further improve clarity and coverage.
Circularity Check
No significant circularity: standard survey organization
full rationale
This is a literature survey paper whose central contribution is a proposed tripartite taxonomy (corpus temporality, question temporality, model capabilities) for organizing existing TQA work. No derivations, equations, predictions, or fitted parameters appear in the provided abstract or described structure. The taxonomy is presented as an organizing device rather than a self-defined or self-cited result that reduces to its own inputs. No load-bearing self-citations, uniqueness theorems, or ansatzes are invoked in a manner that creates circularity. The paper summarizes external literature without reducing any result to quantities defined by its own constructs.

What do these tags mean?
- matches
- The paper's claim is directly supported by a theorem in the formal canon.
- supports
- The theorem supports part of the paper's argument, but the paper may add assumptions or extra steps.
- extends
- The paper goes beyond the formal theorem; the theorem is a base layer rather than the whole result.
- uses
- The paper appears to rely on the theorem as machinery.
- contradicts
- The paper's claim conflicts with a theorem or certificate in the canon.
- unclear
- Pith found a possible connection, but the passage is too broad, indirect, or ambiguous to say the theorem truly supports the claim.
