Embodiment Construction

[0025] The "pragmatic keyword" in the present invention refers to a keyword indicating the function and utility of the information related to the subject word. See the introduction of the background technology for its illustrative examples.

[0026] see figure 1 , the present embodiment provides a pragmatic keyword retrieval method, and its main method flow is as follows:

[0027] Step 101: Obtain the search keyword input by the user;

[0028] Step 102: Add a punctuation mark colon ":" after the search keyword or first use the search keyword to match the pragmatic keyword in the pragmatic keyword vocabulary (see Figure 2), and then add a colon to the keyword after the match is successful ;

[0029] figure 2 The "pragmatic keyword classification" in is used for pragmatic keyword classification navigation, figure 2 The "pragmatic keywords" in are the pragmatic keywords generated by the application results of statistical pragmatic keywords, and only keywords that can have ...

Abstract

The invention discloses a pragmatic key word retrieval method to realize the distinguishing retrieval of semantic key words and pragmatic key words, so as to meet the requirement for distinguishing semantic key words and pragmatic key words during key word retrieval, and further realize the purpose of improving the efficiency of key word retrieval.

Description

technical field [0001] The invention relates to the fields of computer and communication, in particular to a method and device for pragmatic keyword retrieval in information retrieval. Background technique [0002] Search services are the fundamental hub for organizing Internet information communications. However, because the current full-text keyword retrieval does not distinguish between the semantic function and the pragmatic function of the retrieval keywords, it directly leads to low retrieval efficiency. [0003] For example: if the user enters the same search keyword "NBA basketball game live broadcast time", there are actually two completely different application function requirements. One requirement is to retrieve all information related to "NBA basketball game live broadcast time". At this time, the word "time" is a "semantic keyword" that reveals the subject of the target information. Another requirement is to only want to retrieve the specific time of the NBA ...
