The motivation for solving this problem comes from the absence of an automated service to obtain the details of a doctor. To locate a doctor for a specific health condition, people

Also there are very few websites offering this service in India. In contrast, a common medium of communication that can be leveraged for this problem is the mobile phone which offers SMS as an inexpensive channel of sharing information. The challenge that we foresee in such a situation is the ability of the system to respond to natural language queries. We have developed a collection of techniques for addressing these problems. The design approach is guided by the expected usage of the system by a typical user in India and the use of a mobile phone.
