The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The load-bearing mechanism is the six-stage extraction pipeline: keyword retrieval from 6.69 million documents, uniform image rendering and GPT-4o image-to-markdown transcription with LaTeX, GPT-4o structural segmentation, structured extraction of problems, solutions, and numeric identifiers, two-stage quality filtering, and dual-pathway matching using numeric identifiers and the Stella embedding model with GPT-4o verification of each candidate pair. The dual-pathway matching is what lets the pipeline pair problems with solutions even when they sit in distant chapters or separate solution manuals.
What would settle it
Grade a random sample of 200 of the 43,000 verified pairs with two independent human graders, checking whether the LaTeX transcription matches the source image, whether the solution actually addresses the problem, and whether the final answer is correct; if a meaningful fraction fail, the 'high-quality' claim is unsupported.
Extended reading notes
Core claim
On its own terms, the central claim is that SCP-116K is the first large-scale, authentic higher-education science problem-solution dataset, created without synthetic generation, and that its extraction pipeline generalizes across document formats and domains. The pipeline works by rendering every document to images, using GPT-4o to transcribe the images to markdown with LaTeX formulas, segmenting on structural boundaries, extracting problems and solutions with their numeric identifiers, removing incomplete or self-referential entries, and then matching problems to solutions through a dual pathway: numeric identifier matching plus semantic similarity from the Stella embedding model. Each candidate match is verified by GPT-4o for correctness and completeness. This produces, by the paper's count in Section 3.6, 43,000 verified pairs; the abstract's 116,756 figure describes the number of problems after quality filtering, before final pair matching.
Load-bearing premise
The dataset's 'high-quality' label rests on GPT-4o being reliable at every step, converting textbook images into markdown with correct LaTeX, detecting boundaries, extracting complete problems, and judging whether a solution is correct and complete, yet the paper provides no human-annotated sample to check that reliability.
Editorial extensions
If this is right
- Researchers can train or fine-tune models on authentic graduate-level physics, chemistry, and biology problems without synthetic generation, filling a gap left by datasets like CAMEL and ScienceQA.
- The six-stage pipeline becomes a reusable recipe for turning other document collections into question-answering or reasoning datasets in specialized domains.
- A 32B model fine-tuned on 1,000 SCP-116K examples plus STILL-2 data reaches 58.59% on GPQA-diamond, within about two points of o1-mini's 60.61%, so the dataset's content transfers to graduate-level reasoning benchmarks.
- The dataset supplies baselines: o1-mini scores 58.40% and QwQ-32B-preview 55.79% on SCP-116K, leaving room for improvement.
- Expanding collection to more fields and larger scale is the stated next step, which the pipeline's format-agnostic design is intended to support.
Reading between the lines
- The title number 116,756 counts filtered problems, not matched pairs; the usable verified resource is the 43,000 pairs, so benchmark and training claims should be read against that smaller number.
- Because every extraction and verification decision runs through GPT-4o, the dataset quality is upper-bounded by GPT-4o's transcription and reasoning accuracy; an independent open-weight parser run through the same pipeline would test that ceiling.
- The same dual-pathway matching design should transfer to any field whose textbooks number exercises and provide answer keys, such as engineering or quantitative economics.
- A human error analysis on even a few hundred pairs would turn 'high-quality' from an assertion into a measured property; the paper currently leaves that measurement undone.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper presents SCP-116K, an automated pipeline for extracting science problem-solution pairs from heterogeneous documents, and claims a dataset of 116,756 high-quality pairs. The pipeline uses GPT-4o for document filtering, image-to-markdown conversion, segmentation, structured extraction, and verification, while matching combines numerical identifiers and semantic similarity. The authors also report baseline accuracy of o1-mini and QwQ-32B-preview on the dataset and distillation experiments with Qwen2.5-32B-Instruct evaluated on GPQA-diamond. The manuscript releases both the dataset and the extraction pipeline.
Significance. If the claims held, SCP-116K would be a valuable resource: it targets a real gap in higher-education science QA data, is larger than existing public resources, and the pipeline could transfer to other domains. The authors openly release the dataset and pipeline, and they provide baseline evaluations and distillation results, which supports reproducibility. However, the scale and quality claims must be reconciled with the pipeline's own counts and with the absence of human verification.
major comments (3)
- [Abstract; Section 3.5; Section 3.6] The central scale claim is not supported by the reported pipeline counts. The abstract and Section 1 describe '116,756 high-quality problem-solution pairs,' and Section 2 compares against prior datasets on this basis. Section 3.5, however, reports 116,756 problems and 70,000 solutions after quality filtering, and Section 3.6 reports 43,000 verified matched pairs. Since a pair requires at least one problem and one solution, the maximum possible number of pairs after Section 3.5 is min(116,756, 70,000) = 70,000, and the verified output is 43,000. The paper should either redefine the dataset as '116,756 problems with 43,000 verified paired solutions' or provide a count of released pairs that is consistent with the pipeline. As written, the headline scale overstates the available paired resource by a factor of about 2.7.
- [Section 4.2; Section 4.3; Table 1] The distillation experiments select training examples based on semantic similarity to GPQA-diamond questions and then evaluate on GPQA-diamond, which is a form of test-set selection bias. In Section 4.2, the hybrid approach uses '1,000 selected problem-solution pairs from SCP-116K, chosen based on semantic similarity to GPQA-diamond questions,' and Table 1 reports its GPQA-diamond accuracy. This overlap between training selection and evaluation makes the reported improvement (58.59%) an optimistic estimate of general scientific reasoning gains. The authors should evaluate on a held-out benchmark not used for data selection, or at least analyze sensitivity to the selection criterion.
- [Section 3.2; Section 3.4; Section 3.6; Appendix A.5] The 'high-quality' property is asserted without a human check. GPT-4o performs the image-to-markdown conversion, extraction, matching verification, and correctness judgment; no human-annotated sample, error analysis, or inter-annotator agreement is reported. The verification prompt in Appendix A.5 asks GPT-4o to judge whether a solution is 'correct' and 'complete' via its own reasoning, which is the same model family that produced the extraction. This does not establish the dataset's quality independent of the model being assessed. The authors should include a human-evaluated random sample (e.g., 100-200 pairs) with per-stage error rates, particularly for formula rendering and solution correctness.
minor comments (5)
- [Figure 1] Figure 1 contains a typo: 'Probelm' should be 'Problem.'
- [Section 3.7] Section 3.7 says the models generate solutions 'for all problems in our dataset,' but it is unclear whether this refers to all 116,756 problems or the 43,000 verified pairs; please clarify.
- [General dataset documentation] The paper does not report the number of source documents per discipline, the distribution of educational levels, or the release license and format; these details are needed for dataset usability.
- [Section 4.1] Section 4.1 reports accuracy on SCP-116K (58.40% and 55.79%) but does not describe the evaluation protocol, such as exact-match versus model-based grading or the sample size; please specify.
- [Section 2] The related-work comparison in Section 2 would benefit from a quantitative statement of how many of the 116,756 entries are complete pairs after matching, to avoid overclaiming relative to CAMEL's 20,000 pairs.
Circularity Check
No circular derivation; count inconsistency and same-model quality control are correctness risks, not circularity.
full rationale
The paper contains no mathematical derivation loop. The pipeline stages (Section 3) are sequential transformations: document filtering, image-to-markdown conversion, segmentation, extraction, quality filtering, and matching. Each stage reports independent counts (190K problems/80K solutions; 116,756 problems/70,000 solutions; 43,000 verified pairs), so no later quantity is defined solely in terms of an earlier claim. The abstract's '116,756 problem-solution pairs' conflicts with Section 3.6's '43,000 high-quality verified problem-solution pairs,' but this is an internal-count overstatement rather than a circular step: the pair count is not derived from a fitted assumption or self-citation. The use of GPT-4o both to extract (Sections 3.2-3.4) and to verify matches (Section 3.6) is a same-model quality-control concern, not a logical equivalence, since verification is a separate task with a separate prompt (Appendix A.1.5). The distillation experiment selects 1,000 SCP-116K examples by semantic similarity to GPQA-diamond and then evaluates on GPQA-diamond (Section 4.2); this is disclosed selection bias that can inflate the measured gain, but the evaluation is an external benchmark measurement rather than a prediction forced by construction. No load-bearing self-citations are present, so the paper is self-contained in the circularity sense; its weaknesses belong to data-quality verification and internal consistency, not circular reasoning.

Recent breakthroughs in large language models (LLMs) exemplified by the impressive mathematical and scientific reasoning capabilities of the o1 model have spotlighted the critical importance of high-quality training data in advancing LLM performance across STEM disciplines. While the mathematics community has benefited from a growing body of curated datasets, the scientific domain at the higher education level has long suffered from a scarcity of comparable resources. To address this gap, we present SCP-116K, a new large-scale dataset of 116,756 high-quality problem-solution pairs, automatically extracted from heterogeneous sources using a streamlined and highly generalizable pipeline. Our approach involves stringent filtering to ensure the scientific rigor and educational level of the extracted materials, while maintaining adaptability for future expansions or domain transfers. By openly releasing both the dataset and the extraction pipeline, we seek to foster research on scientific reasoning, enable comprehensive performance evaluations of new LLMs, and lower the barrier to replicating the successes of advanced models like o1 in the broader science community. We believe SCP-116K will serve as a critical resource, catalyzing progress in high-level scientific reasoning tasks and promoting further innovations in LLM development. The dataset and code are publicly available at https://github.com/AQA6666/SCP-116K-open.
