Each state corresponds to one of the fields that we wish toextract
e.g. paper title, author name, etc. - True Markov state diagram is unknown at parse-time - can see noisy observations from each state - the sequence of words from the document - Each state has a characteristic probability distribution overthe set of all possible words - e.g. specific distribution of words from the state ‘title’ Docsity.com
parse the observed sequence into a corresponding setof inferred states
Viterbi algorithm
in supervised manner with manually labeled data
bootstrapped using a combination of labeled andunlabeled data Docsity.com
