Author's name is missing.

There is a recurring pattern on this site: if an article begins with a string in square brackets then it contains an author's name.

Let's examine this one [매경닷컴 MK스포츠(고척) = 김재현 기자]:

• "매경닷컴 MK스포츠(고척)" is the name of the source, translating as "Maekyung.com MK Sports (Goche)"

• "김재현" is the author's name itself ("Kim Jae-hyun")

• Finally, "기자" translates as "reporter", which is the title of the author (sometimes that last bit says "intern reporter")

Add this to the fact that 99% (not kidding, look it up) of Korean names have only three-syllables and you got yourself a neat regex.
