INTRODUCTION
This paper presents an Operating system for mobiles, Symbian OS. It is widely used in mobiles. It was designed as part of a joined effort by all mobile manufacturers. A natural language interface is not limited spatially, and thus can accommodate more information in one place. Second, people like to use natural language. Third, a natural language interface for the web can support voice input more easily. When people speak, they want to use natural language. Processing the natural language for filling out forms by spotting field values and using statistical approaches for disambiguating field value meanings. More specifically, a field value is a word or phrase that can be used as a value of a field in a form. the field values for the field departure city may be Los Angeles, New York, or San Francisco. a natural language user input, if each field valueâ„¢s corresponding field can be determined, then the form can be filled out. Consider the user input, find me a flight from Los Angeles to New York. The field values, shown in italics, are Los Angeles and New York for the form of figure 1. If the system knows which field value corresponds to which field in the form, the form can be properly filled out. In this case, Los Angeles belongs to the departure city field and New York to the arrival city field. The field to which a field value belongs to is the field valueâ„¢s meaning. Because a given field value may have multiple meanings within a given domain, the field value must be disambiguated based on the lexical context in which it is used. Each field value will be associated with a list of possible meanings and statistical methods will be used to rank this list of possible meanings.
