5. User Query mapping to ODP
The proposed user model then categorizes the user referred Web with the help of ODP taxonomy. Table 10 contains different query types of the single user in three sessions mapped to keyword based ODP taxonomical categories. Here the category estimation is performed based on a frequency count of each keyword from the user query which is compared with ODP taxonomy. It represents the number of times that particular keyword is matched with the entire list of the ODP structure. In each session there are five different forms of queries like keyword query, Boolean query, phrase query, proximity query and natural language query and the same are represented by Q1, Q2, Q3, Q4, and Q5 respectively.
