US Patent 9807037 Automatically suggesting completions of text

A user may respond to a request of another user by entering text, such as a customer service representative responding to a customer. As the responding user enters text, a completion of the text may be suggested to the responding user so that the responding user may select the completion instead of continuing to enter text. Previous messages between the two users and other information may be used to determine an appropriate completion to the entered text. A topic vector may be determined from previous messages, and a feature vector may be determined from the entered text. The topic vector and the feature vector may be used to identify characters that may follow the entered text.
