Review Comment:
I really appreciated the authors effort in addressing the reviewers comments. However, now the paper is really verbose and descriptive on technical parts. Many parts are more tailored for a technical paper than for a scientific paper. Another concern is on the contribution of this paper. This has been answered in the answers to my previous questions:
"The theory section discusses the theoretical issues that led to the proposed method for solving the challenges. The first challenge is the inability of hybrid systems to answer questions whose answers do not exist in the knowledge base and must be extracted from the text. To solve this problem, an information retrieval based system was used. The next major challenge is the inability of the existing hybrid systems to explain, which was made possible by the probabilistic method. In addition, query decomposition is not performed in existing hybrid systems. The results showed that by performing this operation, which is based on the function of the human mind, the efficiency of the system increases."
This sentence clearly expresses one of the main paper contributions. I would write it in the paper. In addition, the second finding provides an useful insight on the contribution of this paper, it would be useful to read it summarized at the beginning of the paper. I suggest to make the paper less technical by selecting in Section 5 only the scientific important points and leaving the technicalities in a separate section/appendix. In addition, I would pair Fig. 2 with a running example. Such a running example could be use even in Section 5 to better explain the single modules of the system. In addition, a single running example going along the whole paper would better help the reader than many single examples.
Minors:
- page 3, the sentence "Efforts have been made to" is repeated;
- Section 5, "The motivation for using these 3 axes is given in Section 7.3" I would summarize such a motivation here.
- Section 5, last paragraph, triples and facts are used interchangeably.
- Section 5, last paragraph, the sentence "In addition, ... a single sentence" is not clear.
- Section 5.1, second sentence, correct in "This architecture is shown in Figure3. Figure 4 illustrates ..."
