Embodiment 1

[0020] Embodiment 1 of the present invention provides a query parameter processing method, such as figure 1 As shown, it is a schematic flowchart of the query parameter processing method described in Embodiment 1 of the present invention, and the query parameter processing method may specifically include the following steps:

[0021] Step 101: Receive a query request input by a user and acquire query parameters carried in the query request.

[0022] Specifically, for any query request input by the user, the query parameters carried in the query request may generally include:

[0023] (1), the query string, that is, query;

[0024] (2) The query type parameter used to indicate the query type corresponding to this query request, namely search_type; the value of the parameter of search_type may specifically be Normal (that is, ordinary query or ordinary search, also known as a basket search ), Around (i.e. surrounding query or surrounding search), IDQ (i.e. abstract query or ab...

example 1

[0089] Example 1: If a single query request is:

[0090] query=restaurant;

[0091] search_type=AOUND;

[0092] search_data_type = POI;

[0093] adcode=110000;

[0094] x =;

[0095] y =;

[0096] range=;

[0097] category =;

[0098] geoobj=x1:121.3,y1:31.2;x2:121.4,y2:31.4.

[0099] Specifically, by analyzing the value of the original parameter of search_type in the above query parameters, it can be known that this query is a surrounding query, so the specific value of the user's current latitude and longitude information (ie x, y) must exist. However, since the analysis of the original parameter values ​​of the first latitude and longitude parameters (that is, x, y, range) in the above query parameters shows that x, y themselves do not have corresponding values ​​set, therefore, the second latitude and longitude can be obtained through the second latitude and longitude parameters. parameters (ie geoobj) to get the values ​​of x, y. Specifically, in Example 1, x=121...

example 2

[0124] Example 2: If a single query request is:

[0125] query=Line 13%%% (Subway);

[0126] search_type=NORMAL;

[0127] search_data_type = POI;

[0128] adcode=110000;

[0129] category =;

[0130] x = 121.1;

[0131] y=31.3;

[0132] range=;

[0133] geoobj=.

[0134] Specifically, in this query request, since there are special symbols such as brackets and garbled characters in the query, it can be corrected to "Line 13 subway" through preprocessing first.

[0135] Further, it can be seen from the analysis of the original parameter value of search_type in the above query parameters that this query is a common query, so there is no need to perform corresponding RGEO analysis on it; of course, it should be noted that at this time, It can also be parsed by REGO to obtain the actual adcode. However, since this query is a common query, no matter whether the parsed adcode matches the original adcode, there is no need to modify the original adcode accordingly;

Abstract

The invention discloses a query parameter processing method and device. The method comprises following steps: receiving a query request input by a user, obtaining the query parameters carried in the query request, if it is determined that the query data type is the POI (Point Of Interest) type according to the query data type parameters in the query parameters, determining the actual query data type according to the query string in the query parameters and a preset semantic analysis rule; in other words, the information such as the actual query data type of the user can be obtained accurately through analyzing the query parameters carried in the query request input by the user; therefore, the query request of the user can be rewritten subsequently according to the obtained information such as the actual query data type of the user; the query mode more conforming to the actual demand of the user and the understanding of a computer is constructed; and the searching quality of a map searching engine can be improved.

Description

technical field [0001] The present invention relates to the technical field of search, and in particular, to a query parameter processing method and device. Background technique [0002] At present, the search function is an extremely important function of map products or navigation products used by users. Through the search function, users can realize the needs of applications such as specific destinations, lifestyle services or road planning. [0003] Specifically, due to the particularity of address search itself, the collection of required data, the establishment of indexes, etc. are all collected or established by type and region. Therefore, when the search engine retrieves information according to the user's query request , it is extremely important to identify the type, pattern and location information of the query string input by the user, because the correctness of these identification results will directly affect the search quality of the search engine. However, ...
