- Paper.120_Review.2 hasContent "Rule mining is an important problem in the Semantic Web and it has received considerable attention from this research community. AMIE has been an influential system and it is often used as a baseline in more recent works. This paper proposes a new version of this engine, explaining engineering and heuristic-driven techniques that improved its runtime up to 15x. Speeding up the runtime is important to allow the application of this technique to the largest KGs, but the proposed solution does not alter the original algorithm but instead suggests "tricks" to improve the execution. The first two "tricks" are interesting, but the third one is simple (parallelization) while the fourth one (dictionary encoding) is a standard practice in many other scenarios (like SPARQL answering). Because of this, after reading the paper, I was somehow disappointed with the novelty of this work. However, I do value system contribution and the evaluation is comprehensive and convincing. Therefore, I remain positive about this paper. If also other reviewers are concerned about the novelty, then one possibility could be to move this paper to the resource track. I think it's a better fit there. I have more suggestions for improving this paper: 1) Add more citations, especially because you have the space for them. There are other works that perform fact-checking with rules. Also works on dictionary encoding should be cited. 2) Wikidata 2019 was used only on one experiment. It would be nice to include this dataset also for the other experiments, given its large size. 3) Considering tidying up the formal explanation of your method. For instance, - is 'x' in livesIn(x,Berlin) (page 3) a variable or a constant? - Instead of writing $| s : \exists o : r(s,o)| $ why not writing $|{ s : r(s,o) \in K}|$? - Substitutions are partial mappings - From your definition of rules I did not understand if they are safe or not (every variable in the head appears in the body?). - what's p^-? - in some cases p is used as predicate, in others as fact. This is confusing. ---- I read the rebuttal and I confirm my score."".
