This paper proposes a symbol feature-based Hidden Markov Model (HMM). Each state in the model is expressed by some symbol features, and is described by feature lists that draw from regular expressions and text inference; based on which, we use Veterbi Algorithm to extract the information from scientific researchers’ homepages. It works well although there is great information redundancy.
