Situation-based reply candidate presentation method for mobile phone

Recently, many people use mobile devices such as a smart phone or a smart watch. Necessity and importance for creating messages on a mobile device are increasing since users on social networking service are rapidly increasing. Users need to input text for messages with small keys because the screen for the operation is small. In particular, it may be difficult to quickly respond when a user creates a reply on a mobile device. We have proposed method to automatically present multiple reply candidates. The presented candidates correspond to different situations depending on the topic of the received message. The reply process is completed just by selecting the appropriate one from the candidate replies. Rapid response is possible since the user neither needs to create nor revise a reply message on mobile phones, facilitating smooth communication. The effectiveness of our proposed method and its evaluation is done through experiments in Japanese.
