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 object that carries the argument is the approach pattern: a grammar-like schema refined top-down through four linguistic levels, starting from five discourse relations inspired by the Penn Discourse Treebank sense hierarchy and ending in explicit lists of lexical identifiers ('firstly', 'in order to', 'by', 'if') tied to syntactic positions such as subject, verb, object, and adverbial. The patterns do double duty: they extract steps from paper text and they place each step's content into the five dimension-specific components. The supporting machinery is a tree-structure-based similarity measure that represents each step component as a syntax tree whose second level holds subject, predicate, object, and adverbial elements, assigns each node a similarity weight that is halved at every level of depth, and scores a pair of trees by the summed weights of their identical or synonymous nodes; a collection similarity measure then matches each step in one approach to its most similar step in another and averages the two directions; and a bottom-up clustering algorithm merges each approach component or class with its most similar counterpart, allowing one approach to belong to several classes while recording shared constituents as class labels. Class trees over these labels form the five dimensions, and a class-based query mechanism walks the trees top-down, keeping only classes whose label match scores beat their parents' scores.
What would settle it
Take a held-out set of scientific papers from disciplines outside the five training topics, for example biology protocols or mathematics proofs, freeze the five relation types and their lexical identifier lists, and count how many approach steps are expressed through discourse relations the paper excludes, such as comparison, concession, or elaboration, or through unlisted connectives. If a substantial share of steps go unextracted, the claim that five relations cover the steps of scientific approaches, and with it the coverage of the purpose, manner, condition, and effect dimensions, fails.
Extended reading notes
Core claim
The central discovery the paper argues for is that an approach in a scientific paper can be faithfully decomposed into five semantic elements—the action performed, its purpose, the manner or technique used, the condition under which it runs, and the effect it produces—because each element is anchored in a detectable discourse relation between sentences or clauses. On the paper's own terms, an approach is a sequence of steps, each step is one or more sentences, and every step-instantiation falls under one of five discourse relations, so recognizing those relations both extracts the steps and assigns each step's components to the five dimensions. The paper then projects each approach onto each dimension as a collection of step components and builds, per dimension, a tree of classes by repeatedly merging each component or class with its most similar partner, where similarity is computed on tree-structured syntactic representations and class labels record the shared syntactic constituents. The claimed outcome is a multi-dimensional approach space in which exact queries (a string per dimension) and fuzzy natural-language queries both resolve to ranked approach classes, with intersection across dimensions returning only approaches satisfying every specified condition. If this holds, the space is a working index for procedural knowledge, not just a clustering demonstration.
Load-bearing premise
The framework rests on the claim that every step in a scientific approach can be expressed by one of five discourse relations—sequential, purpose-action, action-manner, cause-effect, and condition-consequence—and by the lexical identifiers listed for each, so a step expressed through any other discourse relation or an unlisted identifier falls outside the extraction patterns and the dimension-coverage percentages shrink.
Editorial extensions
If this is right
- Approach retrieval becomes intent-based: a researcher can query the purpose and manner dimensions separately and intersect the results, something a keyword search cannot do because it cannot distinguish an action from a purpose.
- The class trees provide multiple granularities within each dimension, so a query can match at the level of a specific step (such as 'train neural network') or a general class label (such as 'network'), with ranked approaches inside each retained class.
- On the annotated corpus, the action dimension claims to manage 100% of approaches, and the purpose, manner, condition, and effect dimensions claim coverage above 70%, where condition coverage counts each preceding step as the execution condition for the next and effect coverage counts the stated purpose as the realized result.
- The class-based query mechanism is claimed to reduce the search space relative to exhaustive scanning, with the paper noting the special case that a query matching no class can take longer because the whole tree must be traversed to confirm the absence of a match.
- Approaches clustered together on one dimension can land in different classes on another dimension, so the five dimensions cross-cut rather than duplicate one another; the paper illustrates this with approaches that share an action class but split across purpose classes.
Reading between the lines
- The same four-level refinement could be ported to other genres of procedural text, such as experimental protocols, clinical guidelines, or engineering manuals, where steps are organized by purpose, manner, condition, and effect but rely on different lexical identifiers.
- The collection similarity measure could be reused outside retrieval: any task that compares multi-step procedures, such as detecting redundant methods across a literature or organizing methods into a survey, can treat each procedure as a collection of step trees and apply the same matching logic.
- A testable extension is whether the tree similarity measure remains stable under paraphrase, for example active versus passive voice or nominalized verbs, since the current evaluation compares steps that largely share the same surface syntax.
- The five discourse relations are presented as complete for procedural text, but the top-down refinement machinery could also be applied to relations the paper excludes, such as comparison or concession, to see whether adding them raises recall on steps that currently go unmatched without pulling in non-step sentences.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper proposes a pipeline for extracting 'complete approaches' from scientific papers as sequences of steps, using hand-built multi-level pattern grammars organized around five discourse relations (sequential, purpose-action, action-manner, cause-effect, condition-consequence). It then projects each approach onto five dimensions (action, purpose, manner, condition, effect), represents each step component as a syntactic tree, defines a weighted tree-similarity measure and a collection-similarity measure, and clusters approach components into class trees with class labels. Finally, it describes exact and fuzzy query mechanisms over the resulting multi-dimensional approach space. The reported results are extraction F1 values (step-level around 94%, approach-level around 97-98%) on a self-annotated 70-paper corpus, dimension coverage figures, and qualitative query examples on a handful of hand-picked approaches. A pseudocode extension is also sketched in Appendix B.
Significance. If the claims held, the paper would offer a linguistically motivated way to turn procedural text into a structured, queryable resource space, combining discourse-pattern extraction with hierarchical clustering. The pattern grammars are unusually explicit, and the worked examples in Figures 3-7 make the intended semantics readable and the proposed similarity measure very concrete. The small comparison against common-word and SBERT similarity is informative as a motivating illustration. However, the central evaluation is in-sample, the five-relation taxonomy is asserted complete without external evidence, the condition and effect coverage figures are obtained by semantic reinterpretation rather than direct extraction, and the query mechanism is not evaluated at all. These are load-bearing gaps in the evidence for the paper's main claims, not merely presentation issues.
major comments (5)
- [§2.3.2, Tables 3–4; §2.3.3] The extraction evaluation is in-sample and therefore overstates generalizability. Section 2.2 states repeatedly that patterns were obtained 'by analyzing examples of steps within this type,' and Section 2.3.3 reports that unmatched steps are repaired by adding lexical items to the same pattern grammar. The corpus is self-built and the annotation procedure in Section 2.3.1 reports no inter-annotator agreement. Moreover, an approach is counted as matched if at least one of its steps matches (Section 2.3.2), which inflates approach-level F1 relative to the step-level numbers. Tables 3 and 4 therefore measure how well the rules fit the annotators' example set, not how well they generalize to unseen papers. Please add a held-out evaluation, report inter-annotator agreement, and report step-level results without the 'at least one step' relaxation.
- [§2.1 and §2.3.3] The completeness of the five-relation taxonomy is load-bearing but unvalidated. The grammar <step> ::= ... restricts steps to sequential, purpose-action, action-manner, cause-effect, and condition-consequence relations, and Section 2.1 dismisses other PDTB relations with the assertion that they are 'typically not used to express steps' but provides no corpus evidence. Section 2.3.3 concedes that some steps remain unmatched and that coverage is extended by adding lexical identifiers. Since extraction, dimension coverage, and query behavior all operate only on the subset admitted by these five relations, the abstract and Section 4 claim that querying 'ensures strong relevance' is conditional on an unproven completeness assumption. Please test the taxonomy on held-out papers (e.g., report the proportion of annotated steps that fall outside the five relations and how often unlisted identifiers occur) or explicitly restrict the scope of the claims.
- [§3.1, Tables 5–6] The reported coverage of the condition and effect dimensions is not obtained by extraction. Table 5 reports extracted condition coverage of 37.0% and effect coverage of 27.0%; Table 6 raises these to 70.8% and 76.5% by treating the previous step as the execution condition of the next step and by treating the purpose element as the effect when no explicit result is stated. These reinterpretations are a semantic decision made by the authors without validation or a user study, and they change the meaning of the dimension from 'what is explicitly expressed by approach patterns' to 'what can be inferred.' The statement that the condition and effect dimensions are 'able to manage over 70%' of approaches is therefore not supported by the extraction results in Tables 3–4. Please either annotate and evaluate the reinterpreted components directly or present the two sets of coverage figures as distinct claims.
- [§4] The central query claim is not evaluated. Section 4 describes exact and fuzzy querying and illustrates it with five hand-picked approaches, but no retrieval experiment is reported: no precision/recall or nDCG against a relevance-judged query set, no comparison with keyword or embedding retrieval, and no measurement of search-space reduction or latency. The phrase 'ensures strong relevance between user queries and results' is therefore a design claim, not an empirical result. In addition, the pruning rule in Step 2 terminates traversal when no direct subclass surpasses the parent's score; because class labels become more specific toward the leaves, a descendant can in principle match a query better than its parent or immediate child, yet the algorithm would miss it. The paper acknowledges information loss at root nodes and patches only that case; it gives no completeness argument for deeper nodes. Please add a retrieval evaluation and either prove the pruning property or soften the search-space claim.
- [§3.2.1, Eq. (1)] The similarity measure at the core of clustering and querying relies on an unstated axiom and an undefined notion of synonymy. Equation (1) and the preceding text assume that if two nodes in two step-component trees are 'identical or synonymous,' the subtrees rooted at those nodes are also identical or synonymous; this is not generally true for synonymous phrases and is not argued. The paper also never specifies how synonymy is decided (e.g., WordNet, paraphrases, manual resource), even though the similarity scores, class labels, and query matching all depend on it. Please define the synonymy resource and either prove the subtree assumption for the specific tree representation or replace it with a weaker, defensible matching rule.
minor comments (4)
- [Throughout] There are numerous typographical errors (e.g., 'appraoches', 'compoenntes', 'categoried', 'abstracts') and references [10] and [24] are duplicate entries for the same paper; these should be corrected.
- [Table 7] The SBERT column is not reproducible without specifying the exact pre-trained model and pooling configuration used; please provide this information or a reference to the exact checkpoint.
- [Section 6] The conclusion states that step extraction precision on the full-text dataset is 94.31%, while Table 3 reports 94.38; these numbers should be reconciled.
- [Appendix B] The pseudocode extension is not evaluated; if it is kept, it should be presented as a proposal rather than a validated component, or a corresponding evaluation should be reported.
Circularity Check
Pattern rules are fitted on the same self-annotated corpus used to report extraction F1, and the five 'dimensions' are the five discourse-relation patterns renamed, so dimension coverage and extraction verification are partly built in.
-
fitted input called prediction
[Section 2.3.1-2.3.3 (Verification of Approach Pattern)]
"Due to the lack of publicly available datasets for extracting complete appraoches from scientific papers, we collected scientific papers covering various topics and manually annotated approaches. ... This can be addressed by adding specific lexical items into the corresponding lexical-level patterns, thereby expanding the approach patterns so that similar expressions encountered in the future can be successfully matched."
The precision/recall/F1 tables in Section 2.3.2 are computed on this same self-annotated corpus, and Section 2.3.3 describes a fitting loop in which unmatched steps are repaired by adding lexical items to the patterns (e.g., 'This can be addressed by adding specific lexical items into the corresponding lexical-level patterns'). No held-out split or separate test set is described, and no inter-annotator agreement is reported. The reported step recall (93.64% and 93.78%) therefore measures how well the rules were made to cover their own development examples. The extraction 'prediction' is forced by the fitting loop rather than tested on unseen papers.
-
self definitional
[Section 3.1 'Dimensions of Approach', Tables 5 and 6]
"Action is the most fundamental element of a step ... The Action dimension is capable of managing all approaches. ... By treating the previous step in an approach as the execution condition for the subsequent step, the condition dimension is able to manage over 70% of the approaches (as shown in Table 6). ... By treating the purpose element as the actual result for approaches or steps that do not explicitly state a result, the effect dimension is able to manage over 76% of the approaches (as shown in Table 6)."
The five dimensions are 'generalized' from the same five discourse-relation patterns that define what counts as a step, so the coverage counts are computed by the pattern matcher itself. Action's 100% coverage is a definitional consequence of 'most fundamental element of a step', condition's coverage is raised to 70.8% by the definitional rule that the previous step counts as the execution condition, and effect's coverage is raised to 76.5% by counting purpose as the actual result. These are re-descriptions of the pattern definitions, not independent empirical measurements, so they cannot support the claim that the five dimensions manage most approaches.
full rationale
The derivation chain is partly circular. The load-bearing extraction result is evaluated on the same self-annotated corpus used to refine the lexical and syntactic patterns, and Section 2.3.3 explicitly describes the fitting loop in which unmatched steps are repaired by adding lexical items. The reported precision/recall/F1 are therefore in-sample fit statistics rather than held-out predictions; this makes the pattern 'verification' a fitted evaluation. The five dimensions are then obtained by renaming the five discourse-relation patterns into classification axes, and the coverage numbers in Tables 5-6 are definitional: action is 100% by the 'most fundamental element' fiat, condition is boosted by counting the previous step as the condition, and effect by counting purpose as the result. The central 'strong relevance' claim is not itself shown to be circular; it is simply not quantitatively evaluated, since Section 4 provides only illustrative query examples. Self-citations to the authors' prior resource-space and CECW work ([2], [10], [24]) are used for framing or as baselines, not as uniqueness theorems, so they do not add circularity. Overall, the extraction and dimension-coverage claims partially reduce to their own definitions and fitting procedure, while the tree-similarity and clustering algorithms retain independent content, so the paper is partially circular rather than wholly so.

assumptions (4)
- domain assumption Five discourse relations (sequential, purpose-action, action-manner, cause-effect, condition-consequence) are sufficient to express every step in scientific approaches.
- domain assumption A step's meaning is captured by subject, verb, object, and adverbial slots, and relation identifiers appear only in the slots enumerated in the patterns.
- ad hoc to paper If two nodes in different step trees are identical or synonymous, the subtrees rooted at those nodes are also identical or synonymous.
- ad hoc to paper Class-based query pruning, where a parent class is deleted when a subclass has a higher matching score, preserves retrieval completeness.

Approaches form the foundation for conducting scientific research. Querying approaches from a vast body of scientific papers is extremely time-consuming, and without a well-organized management framework, researchers may face significant challenges in querying and utilizing relevant approaches. Constructing multiple dimensions on approaches and managing them from these dimensions can provide an efficient solution. Firstly, this paper identifies approach patterns using a top-down way, refining the patterns through four distinct linguistic levels: semantic level, discourse level, syntactic level, and lexical level. Approaches in scientific papers are extracted based on approach patterns. Additionally, five dimensions for categorizing approaches are identified using these patterns. This paper proposes using tree structure to represent step and measuring the similarity between different steps with a tree-structure-based similarity measure that focuses on syntactic-level similarities. A collection similarity measure is proposed to compute the similarity between approaches. A bottom-up clustering algorithm is proposed to construct class trees for approach components within each dimension by merging each approach component or class with its most similar approach component or class in each iteration. The class labels generated during the clustering process indicate the common semantics of the step components within the approach components in each class and are used to manage the approaches within the class. The class trees of the five dimensions collectively form a multi-dimensional approach space. The application of approach queries on the multi-dimensional approach space demonstrates that querying within this space ensures strong relevance between user queries and results and rapidly reduces search space through a class-based query mechanism.
