I'm working on the abstract of my paper. According to the edition of my professor, the last sentence of the abstract is like:
The results also reveal some limitations of current outlier detection systems, which ...
My question is:
Should I add "the" before "current outlier detection systems" because they are aforementioned and this is thus not the first time the reader sees them. Is this a general statement so that we should use zero article?
What if I instead say: "... limitations of (the) existing outlier detection systems, ..."? Should I use "the" or not?
The difficult part I find in choosing whether to use zero article or not is to determine "how general is general".
Many thanks for your advice.
