7. The first electronic device of claim 6 , wherein the instruction determines whether the conversation satisfies the recommendation criterion by applying a keyword parsing process on the conversation to identify whether at least one keyword is in the conversation, determining whether a sentence having the at least one keyword is a negative sentence if the at least one keyword is in the conversation, and determining that the conversation satisfies the recommendation criterion if the sentence is not the negative sentence, wherein each of the at least one keyword is a name or an appellation of a person, a date and/or time, an activity, or a place.
6. A first electronic device, comprising: an input unit; a display unit; memory; one or more processors; and one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions: to listen to a conversation on the first electronic device and a second electronic device; to determine whether the conversation satisfies a recommendation criterion; to determine whether at least one suggestion information exists in a database if the conversation satisfies the recommendation criterion, wherein the database comprises a local database associated with a plurality of applications installed in the memory; to automatically launch an associated application among the applications and to display at least one suggestion option related to the at least one suggestion information on a user interface of the associated application on the display unit if the at least one suggestion information related to the associated application exists in the database; to select a target option among the at least one suggestion option; to transmit at least one part of the at least one suggestion information related to the selected target option to the second electronic device; to display the at least one part of the at least one suggestion information related to the selected target option on the display unit and the second electronic device; to monitor a feedback from the second electronic device associated with the at least one part of the at least one suggestion information related to the selected target option; and if the feedback is positive, to store the at least one part of the at least one suggestion information related to the selected target option back to one of the applications installed on the first electronic device; and if the feedback is negative, continuously to listen to the conversation on the first electronic device and the second electronic device.
