The Evolution of Artificial Intelligence in the Digital Economy: An Application of the Potential Dirichlet Allocation Model
Round 1
Reviewer 1 Report
This manuscript used the Derwent Innovation Index as the data source and analyzed all the patent texts through the LDA theme model. Results revealed that AI technology is upgraded from chips, sensing, and algorithms to innovative platforms and intelligent applications. However, some issues should be addressed before it can be recommended for publication.
1. In the introduction part, the authors briefly introduced the development of AI technology. More detailed background about AI should be added in this part by citing some typical references on the application of AI in various fields. Such as:
AI in agriculture (Jha, K., Doshi, A., Patel, P., & Shah, M. (2019). A comprehensive review on automation in agriculture using artificial intelligence. Artificial Intelligence in Agriculture, 2, 1-12; Dharmaraj, V., & Vijayanand, C. (2018). Artificial intelligence (AI) in agriculture. International Journal of Current Microbiology and Applied Sciences, 7(12), 2122-2128.),

Title: The Evolution of Artificial Intelligence in The Digital Economy: An Application of the Potential Dirichlet Allocation Model.
Authors: Wang Jun , Shan Chunyi * , Zhu Yongming.
This paper aims to explore the evolutionary process of AI in the era of the digital economy to indicate the next stage of AI development. And this paper adopts the Potential Dirichlet Allocation Model to analyze the evolutionary process, and at the same time, combines the current situation of Chinese research to accelerate the development of China's AI and improve its international competitiveness.
This paper is characterized by the fact that the researchers used the LDA model (Latent Dirichlet Allocation) to explore the technological development of artificial intelligence, and this is in contrast to previous research that adopted the bibliometric method as mentioned by the authors.
In fact, as a reader, I enjoyed tracking the development of artificial intelligence, and in the recommendations made by them, which I felt added to knowledge and important for decision makers, graduate students, and researchers. These are strengths of the research, in addition to the researchers' persuasive style.
In spite of all that I have a few very minor notes:
- The abstract is very well written and expresses the paper's content and method perfectly. But I would have preferred that the objective of the paper be written in the abstract.
- Introduction and research background: I suggest that researchers mention the concept of artificial intelligence; So that if a non-professional person reads the paper, he can understand what artificial intelligence is.
- In the first paragraph of the research background; I suggest that researchers write what it refers to "[6]" instead of “is also like this [6] “, as well as mentioning the reference number.
- The first point of the research methodology; Please check the sentence highlighted in red “Aiming at the evolution of artificial intelligence technology, this paper introduces the LDA topic model into the topic mining of artificial intelligence technology in the subject of Derwent patent data. This paper intends to study artificial intelligence from two aspects: technical topic strength and technical topic content”.
- Notes on general appearance:
1. on the fourth page; Please move the point 3.2.2 at the end of the paper to the next page.
2. on page ten; Please move the point “5. Conclusions” at the end of the paper to the next page.
3. Please explain the abbreviation that appeared in the conclusion “GPU”. Is it an abbreviation for " Graphics processing unit”?

Reviewer 3 Report
The authors used the Derwent Innovation Index as the data source to apply artificial intelligence techniques for the analysis of the evolutionary process, and the combination of the current situation of Chinese research to accelerate the development of China's AI and improve its international competitiveness. The paper is interesting, but bit must be restructured, and the language must be more clear. It was very difficult to understand the purpose of the paper at the beginning. The abstract must be more clearly presenting the background summary, the purpose, and summary of the results. The introduction must also present the main contributions of the research. The research background is fine, but the inclusion of a summary table with the advantages and disadvantages of the previous studies will benefit. Sections 3 and 4 the language must be refined. Also, section 6 is part of a discussion section, and it must be before the conclusions. Also, more recent references must be included.

Reviewer’s Comments
A minor revision is being suggested for Manuscript No.: Sustainability-2100096, titled, "The
Evolution of Artificial Intelligence in The Digital Economy: An Application of the Potential
Dirichlet Allocation Model". The following are the observations/corrections that needs to be
incorporated:
1. Abstract, Line 13-14: “From the patent.... ”, sentence must be rewritten appropriately.
2. Introduction, Line 41-42: “And this paper…..”, sentence must be rewritten
appropriately.
3. Authors must avoid the unnecessary capitalization, suggested to check in the complete
manuscript and revise.
4. Research background: Author must add some more relevant literature and identify the
research gap, afterwards appropriate objectives must be formulated and should be
properly mentioned in the last paragraph of the same section.
5. Research methodology, Line 113-114: “Li Xiangdong and Zhang Jiao”,
appropriate style of citation must be followed.
6. Results and discussion: Currently the Results and discussion contains only the results,
discussion is totally missing. Authors are suggested to identify the similar work
published recently and compared the obtained results with the existing work.
Conclusions: Authors must rewrite the conclusions and summarize major findings in
150-200 words max. Conclusions must contain major findings of your work in numbers
and major takeaway for the reader.
7. Recommendations and Practical Implications: This section contains major two things
(i) Recommendations: Which indirectly the future work, it can be integrated with the
conclusions with a separate paragraph of 50-100 words max.
