I considered whether the semantic-prosody coding is even more fragile: the Chinese 'positive prosody for opening ceremony' rests on 2 of 30 VP instances, and English 'negative prosody in women's boxing' on 2 co-occurrences. Those are real overclaims in the abstract. However, the prosody analysis is downstream of the topic selection: the node words ('奥运会', '开幕式', '体育', 'medal', 'opening ceremony', 'women') are chosen from the manually merged topic set. If the merge is arbitrary, both the macro topic priorities and the micro prosody results can shift. The paper would therefore need to make the original LDA topics and the merging protocol available and demonstrate inter-annotator agreement before the central comparative claims can be accepted. Independent support otherwise: the paper does provide concrete frequency counts for collocation patterns and topic keyword tables, which is useful, but those counts do not validate the topic labels.

Every downstream conclusion about what each media system 'focused on' follows from these merged labels: 'sportsmanship,' 'doping controversy,' and 'new technologies' (Chinese) and 'female athletes,' 'medal wins,' and 'eligibility controversies' (English) are all post-merge constructs. If another analyst grouped the original 9/12 topics differently—for example, separating athlete names like Zheng Qinwen, Wang Chuqin, and Fan Zhendong into distinct athlete-story topics instead of one 'outstanding achievements' topic—the comparative 'focus' claims would likely change. This is not a style complaint: the central comparative result is not reproducible without the original topic lists and a validated merging protocol.

The authors built a corpus of 715 Chinese and 499 English news reports (863,572 tokens) from ten outlets per language. They ran LDA separately on each subcorpus, selected topic numbers by coherence (9 for Chinese, 12 for English), and then manually merged these into 7 Chinese and 6 English topics. For the most frequent topics, they analyze extended meaning units: for Chinese, patterns involving '奥运会' (Olympics), '开幕式' (opening ceremony), and '体育' (sports); for English, patterns involving 'medal', 'opening ceremony', and 'women'. The central claims are that Chinese and English media share topic interests in the opening ceremony, athlete performance, and sponsorship brands; that Chinese media additionally emphasize sports spirit, doping controversies, and new technologies; and that English media additionally emphasize female athletes, medal wins, and eligibility controversies. The paper further claims differences in semantic prosody: positive prosody for Chinese coverage of the opening ceremony and sports spirit, positive prosody for English coverage of female athletes, and negative prosody for English predictions about opening ceremony reactions and women's boxing controversies.","tokens_in":11429,"tokens_out":4420,"duration_ms":45627,"significance":"If the descriptive contrasts survive close scrutiny, this paper would be a useful contribution to cross-lingual and cross-cultural discourse analysis of global media events. The combination of topic modeling, LLM interpretation, and corpus phraseology is timely, and the authors provide concrete frequency counts and example sentences for each pattern, which lends transparency to the micro-level analysis. The corpus construction is careful, including a defined time window, explicit selection criteria for outlets, and a nontrivial token count. The study also raises an interesting methodological possibility: using LLMs to bridge the gap between LDA keyword clusters and interpretable topic meanings. However, the paper's central comparative findings rest on a manually merged topic solution that is not documented or validated, and the abstract overstates the prosody findings for the Chinese opening ceremony. As presented, the work is more a promising pilot than a fully reproducible study; the substance is salvageable with additional detail and analysis.","major_comments":[{"comment":"The paper states that the statistically optimal solutions (9 Chinese topics, 12 English topics) were reduced to 7 and 6 topics 'after manual evaluation and merging of keywords... based on their relevance to the research questions and practical significance.'

However, the paper's own counts for the '在 + 开幕式 + 上 + VP' pattern are 28 objective instances and only 2 positive instances. With 28 of 30 instances objective, 'positive semantic prosody' is not an accurate characterization of the opening ceremony pattern; the finding is that the pattern is predominantly objective with rare positive instances.

The detailed phraseology analysis (frequencies, example sentences, semantic categories) for node words like 'opening ceremony,' 'gold medal,' and 'women's' is the actual empirical content, and it reads as careful, small-scale corpus work. The authors cite the relevant prior LDA-on-Olympics study [2] and position themselves as an extension.\n\nSoft spots, in order of severity:\n1. The abstract says Chinese reports show 'positive semantic prosody' in describing the opening ceremony; Table II and Section V-A say 28 of 30 cases are objective, 2 positive. That's a direct overstatement.\n2. The manual merge from the statistical optimum (9 Chinese, 12 English topics) down to 7 and 6 is not operationalized, not validated, and no inter-annotator agreement is reported. The stress-test note is right: different merging could shift the 'focus' findings. The original topic lists are absent—only the merged tables are shown.\n3. No code, data, or statistical checks; the corpus is described but not shared. For a descriptive study this is not fatal, but it limits reproducibility.\n4. The LLM step uses the model's internal knowledge to generate keyword meanings, which is a form of interpretation; the paper acknowledges this but doesn't test robustness to prompt or model variation.\n\nOn the positive side, the authors are transparent about the manual step—they don't hide it—and the linguistic analysis itself is concrete and checkable. The central descriptive contrast (Chinese focus on national achievement, sports spirit, doping; English on female athletes, eligibility, controversy) is plausible and consistent with the data shown, but it rests on the merged topics.\n\nWho this is for: people working on media framing of mega-events, corpus-assisted discourse studies, and LDA applications in applied linguistics. A serious referee could give useful feedback; the paper deserves a round of revision rather than desk rejection, mainly to fix the abstract overclaim and to share (or at least document) the topic-merge procedure.\n\nMy verdict: conditionally publishable after those corrections.

Analyzing 715 Chinese and 499 English news reports with LDA topic modeling, LLM-assisted topic interpretation, and corpus phraseology, it finds shared focal topics — the opening ceremony, athlete performance, sponsorship brands — plus distinct national emphases: Chinese coverage foregrounds Chinese athletes, sports spirit, new technologies, and doping-test controversies, while English coverage foregrounds female athletes, medal tallies, and eligibility fights. It then claims the two media systems differ in tone as well as topic: Chinese patterns such as '在开幕式上 + VP' and '中国体育 + (N) + VP' are mostly objective and turn positive for ceremony audiovisuals and sports spirit, while English patterns such as 'V + gold medal' and 'women's + N' are positive for female athletes but negative when predicting opening-ceremony reactions and discussing women's boxing.

The paper pairs this corpus-linguistic unit with two computational tools. LDA (Latent Dirichlet Allocation), a Bayesian topic model, produces weighted keyword lists for each latent topic; the authors then merge those lists, choose a high-weight node word per topic, and count its co-occurrence patterns. The second tool is an LLM prompt framework with two stages: a retrieval stage asks the model to supply detailed meanings for each keyword, and a topic stage feeds keyword weights, retrieved meanings, and a human's rough topic description back to the model to generate a coherent discourse-level interpretation. The phraseological counts — '在 + modifier + 奥运会', '中国体育 + (N) + VP' on the Chinese side; 'V + (modifier) + gold medal', 'women's + (modifier) + N' on the English side — are where the paper locates semantic prosody, which it treats as the consistent evaluative coloring that a word acquires from its habitual contexts.","core_discovery":"The paper's central claim is that the discourse of the Paris Olympics in Chinese and English media is neither identical nor arbitrary: it clusters into comparable topic spaces with systematic national differences. Both corpora yield shared topics — opening ceremony, athlete performance, sponsorship brands — while Chinese media uniquely foreground tennis and table tennis standouts, sports spirit, doping-test controversy, and Olympic technologies, and English media uniquely foreground influencer athletes, female athletes' performance, and eligibility disputes. At the micro level, the paper claims the two media differ in phraseological patterning and semantic prosody. Chinese reports favor prepositional constructions such as '在 + modifier + 奥运会' and '中国体育 + (N) + VP', which are predominantly objective or positive, especially for the opening ceremony and sports spirit. English reports favor verb-led patterns such as 'V + (modifier) + gold medal' and 'women's + (modifier) + noun', positive when celebrating medal wins and female athletes, but negative when predicting post-ceremony criticism and in women's boxing coverage.
