Review Comment:
The revised version of the paper reads significantly better than the previous one. All the major concerns raised earlier have been addressed in this version, including a clear statement of the paper contributions, detailed information on the design choices and implementations as well as improved figures and interesting discussion on results.
There are a few minor comments and suggestions for the current version as follows -
- Section 1, page 2, line 26-27 --> This statement is missing a reference to the previous methods that have combined the structure and semantics. Please add them.
- Section 1, Figure 1 seems to a be a bit misplaced here - since the reader is not yet introduced to the details of the implementation, the different metrics already shown here seem confusing and the figure cannot be understood fully. Perhaps a simpler variation of the figure or a part of the figure can be shown here as an example.
- Section 1, page 3, line 10 - the evaluation of entity similarity in KGs --> do the authors mean concept similarity here?
- Section 2.2 Related work --> this section needs some restructuring, while the paragraph heading is Word similarity, there are mentions of concept similarity as well in paragraphs 1-3. Then again we come back to word similarity in para 4. Perhaps a separate heading for concept similarity works can be added?
- Section 3.1, page 7, line 16 --> were all the nodes in Wikidata mapped to an abstract in DBpedia? if not, what is the overlap and how is the missing information handled?
- Section 3.1, page 7, line 34 --> The explanation for the Class similarity seems to be a bit vague. Could the authors add an example here to elaborate on how this similarity measure is obtained?
- Section 3.3, page 9, line 33 --> what is the rational behind choosing the lowest numeric ID here? does this choice make any significant difference or is it inconsequential?
- There are several different links to google drive for the different datasets as footnotes in the paper. Are these dataset links also included in the main Github repository? If yes, then perhaps a single reference to the repo where one might find the dataset links (clearly specified) would be better. If not so, can the links be all added in the readme file for better organization and ease of reuse?
