Hi Lina,
I have also tried like you for person's data set and end up
with the situation of yours, Then, I have collected some sentences (more
than 100 for a single person's name) from wikipedia and google, related to
the persons who I would like to add in the training file and then tagged
like you did, finally it worked for me.
Ex. <START:person> Albert Einstein <END> was a German-born theoretical
physicist. <START:person> Albert Einstein <END> was born at Ulm, in
Württemberg, Germany, on March 14, 1879. <START:person> Albert Einstein
<END> is best known for his mass–energy equivalence formula E = mc².
