I really think that the story of Frankenstein and the life of Mary Shelley have a lot in common. First of all, she did not have a "normal" life because of her family and her problems as a child and as a woman, and the monster was not created to live a "normal" life.
The author of the article tries to emphasize the idea that Mary Shelley in some way wanted to express what she was living and what she was during her life, and she did it through out the monster in Frankenstein.
Mary Shelley was an educated woman, who during her whole life was looking for information and increasing her knowledge, and the monster was created to be intelligent and to know a lot of things. Those are similarities that really let us interpret that the monster is a reflection of the author Mary Shelley.
It is very interesting that some authors write their own stories hided behind the characters' story. I think that it is a great idea of hiding your story and let the reader interpret it and find out that actually it is the author's own story.
