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 object is the dataset itself, organized around a simple/complex equation split. A simple problem has exactly one operation from addition, subtraction, multiplication, or division; a complex problem combines several operations, and the annotation pipeline records the Bengali question, a normalized equation such as $X = 4.0 \times (7.0 + 3.0)$, and the solution 40 in a separate column. The construction procedure, translation with cultural adaptation, an answer column, and a verification check for duplicates, inconsistent equations, and ambiguous wording, is what converts raw source problems into the claimed 22,441 verified items.
What would settle it
Independently re-check a random sample of the released 22,441 items, say 300 to 500 problems, by solving each equation and scanning for exact or near-duplicate Bengali questions; if a substantial fraction has wrong solutions, inconsistent equations, or duplicates, the central claim of a carefully verified, comprehensive corpus fails. The check is concrete because the dataset files are public, so the sample can be drawn and audited without the annotation team.
Extended reading notes
Core claim
The dataset contains 22,441 problems, of which 5,412 are simple equations (1,419 addition, 1,266 subtraction, 1,303 multiplication, 1,391 division) and 17,029 are complex equations that combine operations. The distinguishing contribution is the complex subset, which the original Bengali benchmark had relatively few of; adding it is what makes PatiGonit22K, in the authors' account, a more comprehensive benchmark. Each problem is stored with its Bengali question text, a normalized equation, and the final numeric answer, and the authors claim that translation, cultural adaptation, and bilingual verification ensure mathematical correctness and consistency.
Load-bearing premise
The dataset's reliability rests on the assumption that the bilingual annotators' verification, described in Section 3.3, actually preserves mathematical correctness and removes duplicate or erroneous problems.
Editorial extensions
If this is right
- Bengali NLP models can now be trained and evaluated on 22,441 annotated problems rather than the earlier 10,000, with a much larger pool of multi-operation problems to test multi-step reasoning.
- The 17,029-problem complex subset gives a concrete stress test for equation generation: a model that solves only single-operation problems will score poorly on the full benchmark, making difficulty-level breakdowns meaningful.
- Because every item carries a separate answer column, automatic evaluation of predicted numeric answers is straightforward, supporting Bengali educational NLP tools such as automated tutoring and answer checking.
- The dataset's public release provides a fixed reference point for comparing future transformer and large-language-model methods for Bengali math word problems.
Reading between the lines
- Beyond the paper, the high complex-to-simple ratio (17,029 to 5,412) suggests that overall benchmark accuracy will be dominated by multi-operation performance, so publishing per-type breakdowns will matter more than a single averaged score.
- A natural extension is to measure how the English-to-Bengali translation step changes problem difficulty; one could compare model accuracy on the translated Bengali items against accuracy on the original English source items to separate language effects from reasoning effects.
- A useful methodological extension is to have an independent bilingual team re-annotate a sample and report agreement rates, which would give users a quantitative handle on the verification step and support use of the dataset as training data.

Referee Report
Summary. The paper introduces PatiGonit22K, an expanded Bengali mathematical word problem dataset that grows the original PatiGonit dataset from 10,000 to 22,441 problems. The additional problems are obtained by translating and adapting English MWPs from MAWPS and MATH23K, and the dataset is split into 5,412 simple single-operation equations and 17,029 complex multi-operation equations. The authors describe an annotation pipeline with translation, cultural adaptation, answer-column addition, and quality verification by bilingual annotators. The paper presents dataset statistics, one example, and a data-availability declaration, but no experiments or evaluation of the dataset itself.
Significance. If the released dataset is accurate and genuinely contains the stated number of complex Bengali MWPs, it would be a useful resource for low-resource Bengali MWP research and could support training and evaluation of reasoning models. The paper's main value is the dataset artifact, not a new method. The authors explicitly build on prior sources and describe their annotation steps, which is appropriate for a dataset paper. However, the central claims are currently not verifiable because the data link is absent, the headline statistics are inconsistent, and the verification process is not quantified. These are fixable issues, but they are load-bearing for the contribution.
major comments (3)
- [Table 1 and Section 3.2] The counts in Table 1 are internally inconsistent. The four simple-operation counts sum to 1419 + 1266 + 1303 + 1391 = 5379, yet the table reports "Total Simple Equations" as 5412, and the text in Section 3.2 repeats the 5,412 figure. The discrepancy is 33 items, and no explanation is given. Since the distribution of simple versus complex equations is a headline statistic of the dataset, this arithmetic inconsistency must be resolved before the dataset description can be considered reliable.
- [Declarations (Data availability)] The Declarations section states that the dataset is publicly available and says researchers can access it through a link, but it provides only the text "Dataset of PatiGonit22K (Original Data) (Mendeley Data)" with no working URL. Without a resolvable link, the central claim of a public benchmark cannot be verified. The authors must supply the actual Mendeley Data DOI or URL.
- [Section 3.3 (Dataset Annotation)] The quality verification step is described only qualitatively: "Problems failing these checks were corrected or removed." The paper reports no inter-annotator agreement score, no count of corrected problems, no count of removed duplicates, and no held-out validation subset. These numbers are essential for a dataset paper whose central claim is that the data are "carefully verified" and mathematically correct. Without them, the reliability of the release is an assertion rather than a demonstrated property.
minor comments (5)
- [Title] The title on the first page reads "A COMPREHENSIVEDATASET" with a missing space between "COMPREHENSIVE" and "DATASET."
- [Figure 2 caption] The caption says the figure "illutrates" an overview; this should be "illustrates."
- [Abstract] The abstract calls the dataset a "balanced benchmark," but the reported distribution is 17,029 complex versus 5,412 simple equations, i.e., roughly 76% complex. Please clarify what aspect is balanced or adjust the wording.
- [Related Work] Reference [4] (GSM-Plus-BN) includes the current paper's co-author Swastika Kundu as a co-author. This is a relevant self-citation and should be explicitly flagged as such for transparency.
- [Formatting] The manuscript has several formatting inconsistencies, such as the "APREPRINT" header on page 2, inconsistent use of "PatiGonit22k" versus "PatiGonit22K," and broken spacing in the equation example. These should be cleaned up in a revision.
Circularity Check
No circularity: PatiGonit22K is a dataset-construction paper whose enumerative claims are direct reports, not reductions to fitted inputs or self-citations.
full rationale
PatiGonit22K is a dataset-construction paper, not a derivation: there is no fitted parameter, predicted equation, uniqueness theorem, or reduction of a target result to its inputs. The central claims (22,441 total problems; 5,412 simple; 17,029 complex) are enumeration statements about the released artifact, and the simple/complex classification is a dataset-design convention rather than a prediction derived from the same data. The construction pipeline described in Section 3.1 translates and adapts external sources (MAWPS, MAWPS-single, MATH23K) and extends the existing PatiGonit benchmark; citing those sources is legitimate external support. The one self-citation (reference [4], GSM-Plus-BN, in related work) is not load-bearing for this dataset's construction. Section 3.3's verification claim is an asserted quality-control procedure, not a mathematically derived output, so it cannot be circular. The Table 1 count inconsistency (1,419 + 1,266 + 1,303 + 1,391 = 5,379 versus 5,412 reported) and the missing data URL are verifiability and correctness concerns, not circularity.

Mathematical Word Problems (MWPs) are an important benchmark for evaluating natural language understanding and quantitative reasoning. Despite recent progress in high resource languages, Bengali remains underexplored due to the limited availability of large scale annotated datasets. In this work, we introduce PatiGonit22K, an expanded Bengali MWP dataset containing 22,441 problems, developed by extending the original PatiGonit dataset with a substantially larger collection of complex mathematical problems. The dataset includes both simple and multi operation equations, providing a balanced benchmark for evaluating mathematical reasoning across different difficulty levels. Each problem is carefully translated, annotated, culturally adapted, and verified to ensure linguistic consistency and mathematical correctness. By increasing both the scale and complexity of Bengali MWPs, PatiGonit22K provides a more comprehensive resource for future research on mathematical reasoning and educational NLP applications in low resource languages.
