Use of "it" in titles

Is the following question title grammatical or not, despite some missing articles?

Way of obtaining Chomsky normalform, does it influence performance of CYK parser?

P.S.: is there an English grammar web site that shows the used "it" pronoun pattern or a similar pattern? Maybe something along Participial Phrase?

Solution 1:

Leaving the question of articles aside, in your example "it" is a pronoun that refers to the entire first clause, so there's nothing objectionable about it.

The comma seems a little weak there for a question title, however. I would probably prefer a colon instead:

Solution 2:

Use of "it" in this case is not wrong (a kind of "anastrophe"); the "it" is referring to "way of obtaining Chomsky normalform"

However, I would rephrase the title, so that, not only does it eliminate "it", it makes it easier to read :

Does the way of obtaining Chomsky normalforms influence performance of CYK parser?

Solution 3:

The use of "it" is fine; the comma-splice isn't.

Divide those independent clauses with a semi-colon, colon, or n-dash, eh?

Also, it's fine to ellipse words whose meaning is implicit ("Way of", if there's only one way), but not determiners (e.g. "the" and either a determiner or something else to identify a particular "way of"):

"Obtaining Chomsky normalform: Does it Influence the Performance of the CYK Parser?"

or:

"My Super-duper New Way of Obtaining Chomsky normalform: Does it Influence the Performance of the CYK Parser?"

or:
