Background

In the existing Instant Messaging (Instant Messaging) technology, multimedia contents (audio, video, pictures and the like) enrich the information amount which can be acquired by a user, but the multimedia contents are more common or text information, and the information amount transmitted by the Instant Messaging technology is too large, so that the user is difficult to quickly grasp key contents when reading information, and for the situation, one of the solutions in the prior art is as follows:

the topic is generated based on the analysis of the information (usually, the analysis of the text information), then the topic is used as an index key word, the information which is the same as or similar to the index key word is associated, and then the topic is distributed to other users, so that a plurality of users can discuss in an instant messaging manner based on the same topic, thereby improving the communication efficiency and assisting the users to quickly grasp the key content of discussion.

However, in the text input, how to quickly introduce a proper topic is not focused and solved by the current text input control.

In a first embodiment of the existing text input control, the following functions can be provided for the user:

first, the user manually inputs a topic guide symbol double-well number "##" in a text input box,

then, the user manually enters the topic name between the two well numbers,

introducing a topic in a mode of # topic name #;

the foregoing parsing based on information specifically includes: with the double well number as a determination symbol, the generated topic is usually stored in a server (for example, the server maintains one or more topic lists, and the topic names of the topics are stored in the topic lists), and the server performs related topic management.

The topic introduction of the first embodiment depends on manual input of a user, so that the efficiency is low, the risk of input errors exists, and the first embodiment is inconvenient for the user to use.

In the second embodiment of the existing text input control, the functions that can be provided for the user are as follows:

firstly, the user manually inputs the single-well sign "#" of the topic guide symbol in the text input box,

then, the user follows the topic name after the single well number, and follows a space "" after the topic name,

introducing topics in a mode of "# topic name + space";

the foregoing parsing based on information specifically includes: with the single well number + space as a determination symbol, the generated topic is usually stored in a server (for example, the server maintains one or more topic lists, and the topic names of the topics are stored in the topic lists), and the server performs related topic management by analyzing the single well number and the space as a topic name regardless of the content between the single well number and the first space.

The problems of the second embodiment are substantially the same as those of the first embodiment.

In addition, because the information presentation of the Instant Messaging (Instant Messaging) technology is to use the information release time as a sorting keyword, when a plurality of topics are discussed alternately, the text input control (referred to as the second embodiment or the first embodiment) is adopted to introduce the topics, obviously, a lot of repeated labor is brought to the user, the input speed is influenced, the enthusiasm of the user for participating in the discussion aiming at a specific topic is influenced, and the stickiness of the user is not easy to improve.

The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
