Abstract:Information seeking process is an important research topic in information seeking behavior. Both qualitative and empirical methods have been adopted in analyzing information search processes with major focus on uncovering the latent search tactics behind user behaviors. Most of the existing works require defining search tactics in advance and coding empirical data manually. Among the few works that can recognize usage patterns automatically, they missed explain the latent rationale behind them. In this paper, we proposed an automatic technique and explicitly model the latent search tactics using a Hidden Markov Model. HMM results show that the identified usage patterns of individual information seeking behaviors are consistent with Marchionini’s Information seeking process model. With the advantages of showing the connections between search tactics and search actions, and the transitions among search tactics, we argue that Hidden Markov Model is a useful tool to investigate information seeking process, or at least it provides a feasible method to analyze large scale dataset.
