The terminal devices 101, 102, 103 may have installed thereon various communication client applications, such as a web browser application, a house source application, and the like.
The terminal devices 101, 102, 103 may be hardware or software. When the terminal devices 101, 102, 103 are hardware, they may be various electronic devices including, but not limited to, smart phones, tablet computers, laptop portable computers, desktop computers, and the like.

It may be implemented as multiple software or software modules (e.g., to provide distributed services) or as a single software or software module. And is not particularly limited herein.
The server 105 may be a server providing various services, for example, a background server providing support for a house source application installed on the terminal devices 101, 102, and 103, and the background server may receive an information retrieval request including location information of a target area sent by the terminal devices 101, 102, and 103, perform a corresponding retrieval operation based on the location information, and return a retrieval result to the terminal devices, for example.

It should be noted that the server may be hardware or software. When the server is hardware, it may be implemented as a distributed server cluster composed of multiple servers, or may be implemented as a single server. When the server is software, it may be implemented as multiple pieces of software or software modules (e.g., to provide distributed services), or as a single piece of software or software module. And is not particularly limited herein.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of an information retrieval method according to the present disclosure is shown. The information retrieval method can be applied to a server (such as the server 105 shown in fig. 1), and comprises the following steps:
In this embodiment, the server may receive, for example, an information retrieval request including location information of a target area sent by a terminal device (e.g., terminal devices 101, 102, 103 shown in fig. 1) through a wired connection manner or a wireless connection manner, and determine, in response to the information retrieval request, a target business turn belonging to the target area based on the location information.
In practice, the terminal device may be installed with a room source application supported by the server. The house-source application may include at least one of: area screening options, target maps. The target area may be an area selected by the user through the area screening option, or an area framed on the target map by the user, which is not specifically limited herein.
The target map may include a Region of Interest (ROI) for characterizing a business district and a Point of Interest (POI) for characterizing a cell. Each region of interest may for example correspond to the position coordinates of the centre point of the business circle it characterizes. Each point of interest may for example correspond to the position coordinates of the central point of the cell it characterizes. The location coordinates may be latitude and longitude coordinates. Further, the region of interest may correspond to a point of interest corresponding to a cell within the quotient circle characterized thereby.
It should be noted that the location information of the target area may include, for example, longitude and latitude coordinates of a location where the target area is located.
Taking the target area as the area selected by the user through the area filtering option as an example, the server may determine the target business turn belonging to the target area from a preset business turn set, for example. For example, a business turn in the set of business turns may correspond to the position coordinates of its center point. The server may perform corresponding calculation on the position coordinates corresponding to the business circles in the business circle set and the position information of the target area to determine whether the position coordinates are included in the target area. If the position coordinates are contained within the target area, the server may determine the business turn as a target business turn attributed to the target area.
Here, for any business circle in the business circle set, the server may determine whether the position coordinates corresponding to the business circle are included in the target area, for example, by using a preset algorithm corresponding to the shape of the target area.
Taking the target area as an irregular polygonal area as an example, the server may determine whether the position coordinate is included in the target area by using a geo-fencing technique, for example. Specifically, the server may determine whether the position coordinates are included in the target region using a ray method. For example, the server may draw a ray in the horizontal direction on a two-dimensional plane, starting from the position coordinates. The server may determine the total number of intersections of the boundaries of the target region with the rays. If the total number is odd, the server may determine that the location coordinate is within the target area. If the total number is an even number, the server may determine that the location coordinates are not within the target area.
Further, taking the target area as a rectangular area as an example, it is assumed that the position information of the target area includes coordinates of the upper right vertex (x1, y1) and coordinates of the lower left vertex (x2, y2), and the position coordinates are (x, y). If x2< x < x1 and y2< y < y1, the server may determine that the position coordinates are within the target area.
In this embodiment, the server may determine the target cell belonging to the target area based on the target business turn.
Continuing to take the example that the target area is the area selected by the user through the area screening option, each business circle in the business circle set may correspond to the cell identifier of the cell included in the business circle set in advance. The server may obtain a cell identifier corresponding to the target business circle, determine a cell included in the target business circle based on the cell identifier, and determine the cell included in the target business circle as a target cell belonging to the target area.
In this embodiment, the server may determine the screening information used for house source information screening based on the target cell. For example, the cell identity of the target cell may be stored in advance in association with the origin identity of the origin within the target cell. The server may obtain the house source identifier of the house source in the target cell based on the cell identifier of the target cell, and then determine the information for screening including the house source identifier.
In some optional implementations of this embodiment, the server may also determine the information for screening that includes the cell identifier of the target cell.
And step 204, acquiring house source information based on the screening information.
In this embodiment, the server may obtain the house source information based on the screening information. The house source information may include a house source identifier of the house source indicated by the house source information, a cell identifier of the cell to which the house source belongs, and the like. For example, if the information for filtering includes the house source identifier, the server may obtain the house source information from the local or connected information storage device based on the house source identifier in the information for filtering.
Alternatively, if the information for screening includes the cell identifier, the server may obtain the house source information from the local or connected information storage device based on the cell identifier in the information for screening.
And step 205, determining a retrieval result based on the acquired room source information, and returning the retrieval result.
In this embodiment, the server may determine a search result based on the acquired room source information, and return the search result to the terminal device that sent the information search request, so that the terminal device displays the search result.
Here, the server may determine, for example, an average house source price and/or a number of house source sets corresponding to the target area based on the acquired house source information, and generate a search result including the determined average house source price and/or the number of house source sets corresponding to the target area. The average price of the house resources may be an average price of the house resources in an actual geographic area corresponding to the target area, and the number of the house resources sets may be, for example, the number of house resources sold in the actual geographic area.
As an example, the server may average prices in the acquired pieces of house source information, and determine the average value as the house source average price corresponding to the target area. In addition, the house sources indicated by the house source information acquired by the server are different from each other, so that the server can determine the number of the acquired house source information as the number of house source sets corresponding to the target area.
In some optional implementation manners of this embodiment, the server may also determine, based on the obtained room source information, a room source average price and/or a room source number corresponding to the target cell, and generate a search result including the determined room source average price and/or the room source number corresponding to the target cell. The average house source price may be an average house source price in the target cell, and the house source set number may be, for example, a set number of house sources sold in the target cell.
As an example, for each target cell, the server may average prices in the acquired pieces of room source information related to the target cell, determine the average value as a room source average price corresponding to the target cell, and determine the number of the pieces of room source information related to the target cell as a room source set number corresponding to the target cell.
In some optional implementation manners of this embodiment, the server may also determine, based on the acquired room source information, an average room source price or a number of room sources corresponding to the target area and an average room source price or a number of room sources corresponding to the target cell, and generate a search result including the determined average room source price or the number of room sources corresponding to the target area and the determined average room source price or the number of room sources corresponding to the target cell.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the information retrieval method according to the present embodiment. In the application scenario of fig. 3, a house source application supported by the server may be installed on the smartphone of the user a, and the house source application may include the target map. When the user wants to know the average price of the house resources in the area B, the area B may be framed in the target map, and the smartphone may send an information retrieval request including location information of the area B to the server in response to detecting that the area B framed in the target map by the user is selected. The server may determine a target business turn attributed to the area B based on the location information of the area B in response to the information retrieval request, where it is assumed that the target business turn includes a target business turn C. Then, the server may further determine the cells included in the target business circle C, and determine the determined cells included in the target business circle C as the target cells belonging to the area B. Here, it is assumed that the target cells include a target cell D1 and a target cell D2. Thereafter, the server may determine screening information for house source information screening including cell identifications of the target cell D1 and the target cell D2. Then, the server may obtain locally the premises information related to the target cell D1 and the target cell D2 based on the cell identifier in the screening information, where the premises information may include the price of the premises indicated by the premises information and the cell identifier of the cell to which the premises belongs. Then, the server may average the prices in the acquired pieces of house source information, take the average value as the house source average price corresponding to the area B, and generate a search result including the house source average price. Finally, the server can return the retrieval result to the smart phone, so that the smart phone can display the retrieval result on the target map.
In the method provided by the above embodiment of the present disclosure, a target business circle belonging to a target area is determined based on location information by responding to a received information retrieval request including location information of the target area, where one business circle includes at least one cell, then a target cell belonging to the target area is determined based on the target business circle, then screening information for house source information screening is determined based on the target cell, then house source information is obtained based on the screening information, so that a retrieval result is determined based on the obtained house source information, and the retrieval result is returned. The scheme provided by the above embodiment of the present disclosure realizes information retrieval rich in pertinence. In addition, the target business circle belonging to the target area is determined firstly, and then the target cell belonging to the target area is determined based on the target business circle, so that the calculation amount can be effectively reduced, and the information retrieval efficiency can be improved.
Referring further to fig. 4, a flow diagram 400 of yet another embodiment of an information retrieval method according to the present disclosure is shown. The information retrieval method can be applied to a server (such as the server 105 shown in fig. 1), and comprises the following steps:
In this embodiment, the server may receive, for example, an information retrieval request including location information of a target area, which is sent by a terminal device (e.g., the terminal devices 101, 102, 103 shown in fig. 1) through a wired connection manner or a wireless connection manner. The server may then determine, in response to the information retrieval request, the various regions of interest included in the map content currently presented to the user in the target map. Wherein the target area is an area framed on the target map by the user. The target map comprises interest areas for characterizing the business circles and interest points for characterizing the cells. The region of interest corresponds to a point of interest corresponding to a cell within the business circle characterized by the region of interest.
Here, the terminal device may have installed thereon a house source application supported by the server. The house-source application may include a target map. Each point of interest may correspond to the location coordinates of the center point of the cell it characterizes. Each business segment may include at least one cell. Furthermore, each region of interest may for example correspond to the position coordinates of the central point of the business circle it characterizes. The location coordinates may be latitude and longitude coordinates.
It should be noted that the location information of the target area may include, for example, latitude and longitude coordinates of a location where the target area is located.
In this embodiment, the server may, for example, record in real time various regions of interest in the map content presented to the user in the target map. After the server receives the information retrieval request, the server can acquire each interest area in the map content currently presented to the user in the newly recorded target map.
In this embodiment, the server may determine, based on the location information of the target region, a target interest region included in the target region in each determined interest region, and determine a quotient circle characterized by the target interest region as a target quotient circle. Here, for each of the interest areas, the server may perform corresponding calculation on the position coordinates corresponding to the interest area and the position information of the target area to determine whether the position coordinates are included in the target area. If the position coordinates are contained in the target area, the server may determine the area of interest as the target area of interest.
In this embodiment, the server may determine, based on the interest point corresponding to the target interest area for characterizing the target business circle, a cell included in the target business circle, and determine the determined cell included in the target business circle as a target cell belonging to the target area.
In step 404, screening information for house source information screening including the cell identifier of the target cell is determined.
In this embodiment, after determining the target cell, the server may determine the screening information for house source information screening, which includes the cell identifier of the target cell.
And step 405, acquiring the house source information based on the screening information.
In this embodiment, the server may obtain the house source information based on the screening information. The house source information may include the price of the house source indicated by the house source information, the cell identifier of the cell to which the house source belongs, and the like. Specifically, the server may obtain the premises source information from a local or connected information storage device based on the cell identifier in the screening information.
In this embodiment, the server may determine, based on the acquired room source information, the average price of the room source and the number of room source sets corresponding to the target area, and the average price of the room source and the number of room source sets corresponding to the target cell, and generate a search result including the determined average price of the room source and the number of room source sets corresponding to the target area, and the determined average price of the room source and the number of room source sets corresponding to the target cell. Here, the server may determine the average house source price and the number of house source sets corresponding to the target area and the average house source price and the number of house source sets corresponding to the target cell by using the related method described in the embodiment shown in fig. 2.
In this embodiment, the server may return the search result to the terminal device that sent the information search request, so that the terminal device may display the search result, for example, display the search result on the target map.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the information retrieval method in this embodiment highlights the limitation that the target area is the area framed on the target map by the user, and the steps of expanding the determination methods of the target business circle, the target cell, the information for filtering, and the retrieval result. Therefore, the scheme described by the embodiment can realize diversified information processing and enrich the content of the retrieval result. In addition, the information retrieval related to the house source is carried out by supporting the user to select the area on the target map in a frame mode, so that flexible map retrieval can be realized, and the retrieval result can be more accordant with the retrieval intention of the user.
