Query processing algorithms for time, place, purpose and personal profile sensitive mobile recommendation

Nowadays more people have started using mobile phone to access information they need from anywhere at anytime. In advanced mobile technology, location service lets users quickly pinpoint their location. However, we believe it has other factors to achieve more efficient service. In this paper, we propose the relationship between 3 factors which are time, place and purpose. In consequence, we have summarized the basic rules to analyze essential data and algorithms to query processing. Furthermore, we are filtering the message with one more factor is personal profile. We also illustrate scenarios in different event, which our query processing can be recommended to push the appropriate message to users.
