Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, as presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
Hereinafter, the terms "including", "having", and their derivatives, which may be used in various embodiments of the present invention, are only intended to indicate specific features, numbers, steps, operations, elements, components, or combinations of the foregoing, and should not be construed as first excluding the existence of, or adding to, one or more other features, numbers, steps, operations, elements, components, or combinations of the foregoing.
Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another, and are not to be construed as indicating or implying relative importance.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which various embodiments of the present invention belong. The terms (such as those defined in commonly used dictionaries) should be interpreted as having a meaning that is consistent with their contextual meaning in the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein in various embodiments of the present invention.
Example 1
Referring to fig. 1, a schematic flow chart of a first method for locating a house according to an embodiment of the present invention is shown, where the method for locating a house according to an embodiment of the present invention is applied to a computer device, and the computer device stores first location data and first address information of a plurality of first house areas.
It should be noted that, according to the information input in advance, the computer device in the embodiment of the present invention acquires and stores the first location data and the first address information of the plurality of first room areas, so as to determine, in a subsequent process, the area/location where the room to be located is located according to the first location data and the first address information of each first room area.
It should be further noted that the house area in the embodiment of the present invention refers to an area where a plurality of houses in the same section/area/range are located.
Exemplarily, if a plurality of houses all belong to the cell a/floor a, then the house areas of the plurality of houses are all the cell a/floor a.
Further, the first position data in the embodiment of the present invention includes one or more of a GPS (Global Positioning System) coordinate, a Beidou satellite navigation System coordinate, a latitude and longitude coordinate, and the like. It should be understood that the position data represents a coordinate point.
Optionally, because the GPS coordinates are widely used and the way of acquiring the GPS coordinates is relatively mature, in a feasible way provided by the embodiment of the present invention, the first position data includes global positioning system coordinates.
Furthermore, in the embodiment of the present invention, the first address information is a character string capable of representing an address.
Exemplarily, if a plurality of houses belong to a cell a, and the address of the cell a is "XX district XX road XX district XX city XX by XX", the first address information of the cell a is a character string of "XX province '," XX city ', "XX district '," XX road ', "XX cell '.
Also, therefore, the process of acquiring the first address information of the cell a may include: after parsing/segmenting/word-dividing the address of the cell a to obtain nouns/characters such as province, city, district, road, cell, etc., the computer device concatenates the nouns/characters to obtain concatenation results/character strings of 'XX province', 'XX city', 'XX district', 'XX road', 'XX cell', 'XX district', and the like, and uses the concatenation results/character strings as the first address information.
It will be appreciated that the computer device stores the first location data and the first address information of the first room area in a manner that can be set according to the actual situation.
Illustratively, in one possible approach, the computer device completes the storing of the first location data and the first address information for the plurality of first room areas based on spreadsheet (Excel) software.
It can be clear that, based on this way, the first position data and the first address information are recorded and modified in an explicit way, and then later-stage operation and maintenance personnel can perform operation and maintenance work more easily.
In a preferred mode provided by the embodiment of the present invention, the computer device stores the first location data and the first address information of each first room area by using Database (Database) software, that is, the computer device stores the first location data and the first address information of the plurality of first room areas based on the Database software.
It may also be clear that the specific type of the database software is the content that can be set according to the actual situation, for example, in a feasible manner, the database software is one of MySQL, oracle, access, and SQL Server.
Therefore, the computer equipment can receive the instruction/operation/command and execute the operation such as modification, addition, deletion, modification, searching and the like on the first position data and/or the first address information of the first house area with higher processing efficiency.
Based on this, the method for positioning a house provided by the embodiment of the present invention includes:
and S110, responding to the house mortgage request, and acquiring the certified address of the house corresponding to the house mortgage request.
It will be appreciated that the certified address comprises an address described in a property certificate.
It can also be understood that the obtaining mode of the certificate carrying address is the content which can be set according to the situation.
Exemplarily, in a feasible manner provided by the embodiment of the present invention, the house mortgage request encapsulates/carries the prover address, and the computer device obtains the prover address by analyzing the house mortgage request.
In another feasible manner provided by the embodiment of the present invention, the house mortgage request carries a photo of a house property certificate provided by the client, and the photo includes the certified address, and further, the computer device identifies the certified address in the photo by using a preset identification method/model, so as to obtain the certified address of the house to be mortgaged by the client.
And S120, converting the certificate address into corresponding second position data.
Namely, the certificate-carrying address is converted into one or more of various coordinates such as a GPS coordinate, a Beidou satellite navigation system coordinate, a longitude and latitude coordinate and the like.
It is understood that the first location data needs to be matched with the second location data, that is, if the first location data stored in the computer device only includes a GPS coordinate, the second location data of the certified address is also a GPS coordinate; and if the first position data comprises the GPS coordinates and the longitude and latitude coordinates, the second position data needs to comprise the GPS coordinates and the longitude and latitude coordinates.
In addition, it can be understood that the manner of converting the certificate address into the coordinate data/position data is a content that can be set according to an actual situation, and can be implemented by using any tool/interface/library/software, which is not limited in the embodiment of the present invention.
Exemplarily, in a possible way, the embodiment of the present invention converts the certified address into the coordinate data based on a geocode JS (JavaScript) library.
And S130, determining at least one second house area in the plurality of first house areas, wherein the distance between the first position data and the second position data is smaller than a preset distance.
It is understood that, in the case where the first location data and the second location data are both coordinates, the distance between each first room area and the room to be mortared can be calculated according to the second location data of the room corresponding to the room mortgage request, that is, the second location data of the room to be mortgaged, and the first location data of each first room area.
Furthermore, if the distance between any one of the first room areas and the room to be mortared is smaller than the preset distance, it indicates that the room to be mortared can be located in the first room area, and therefore the first room area is used as the second room area.
It should be understood that the preset distance is a content that can be set according to an actual situation, and is not limited in the embodiment of the present invention.
And S140, determining at least one third house area, in the plurality of first house areas, of which the first address information is similar to the certificate-loaded address according to a preset natural language processing module.
That is, the computer device will determine the third room area by determining first address information similar to the certified address of the room to be mortared from the stored first address information of the plurality of first room areas using the natural language processing model/algorithm/tool.
It is to be understood that the manner of determining whether the first address information and the certification address are similar is a manner that can be set according to actual circumstances.
Exemplarily, in a feasible manner provided by the embodiment of the present invention, the natural language processing module is configured to determine whether two pieces of input information are similar according to the two pieces of received input information, and then the computer device detects whether each piece of first address information and the corresponding authentication address are similar one by one, and if so, takes a first room area corresponding to the first address information as a third room area.
In another feasible manner provided by the embodiment of the present invention, specifically referring to fig. 2, a flow diagram of a second house positioning method provided by the embodiment of the present invention is shown, where in this feasible manner, the preset natural language processing module includes a named entity identification sub-module, a sentence vector generation sub-module, and a similarity operator module;
further, the S140 includes:
s141, identifying a first named entity in the certificate address by using the named entity identification submodule, and obtaining second address information corresponding to the house according to the first named entity;
s142, inputting the second address information and the first address information of each first room area into the sentence vector generation submodule, to obtain a first sentence vector corresponding to the first address information of each first room area, and a second sentence vector corresponding to the second address information;
s143, calculating the similarity between the second sentence vector and each first sentence vector based on the similarity calculation operator module;
s144, taking the first house area with the similarity between the first sentence vector and the second sentence vector larger than a preset value as a third house area to obtain at least one third house area.
That is, in this feasible manner, the computer device will identify the named entities in the certificate address, i.e. the nouns/characters of province, city, district, road, cell, etc., and concatenate the nouns/characters to obtain the second address information similar to the structure/form of the first address information.
It will be appreciated that in this manner, the first address information stored by the computer device may be viewed as a string of named entities.
Further, the computer device converts the second address information and each piece of the first address information into a sentence vector according to the sentence vector generation submodule, thereby obtaining a first sentence vector corresponding to each piece of the first address information and obtaining a second sentence vector corresponding to the second address information.
Then, based on the similarity degree operator module, the similarity degree of each first sentence vector and the second sentence vector is calculated.
Furthermore, if the similarity between any one first sentence vector and any one second sentence vector is greater than the preset value, it indicates that the certification address corresponding to the second sentence vector is similar to the first address information corresponding to the first sentence vector, and therefore the first house area corresponding to the first sentence vector is taken as the third house area.
It can be understood that the natural language processing module, and the named entity recognition sub-module, the sentence vector generation sub-module and the similarity calculation sub-module in the natural language processing module in the embodiment of the present invention are all contents that can be set according to actual situations.
Illustratively, in one possible implementation provided by the embodiment of the present invention, the sentence vector generation submodule includes a pre-trained Bidirectional code Representation from converters (BERT) based on a converter.
In addition, it can be understood that the preset value is a content that can be set according to an actual situation, and the embodiment of the present invention does not limit this.
Optionally, in order to ensure the accuracy of the third house area, after S143, in a possible manner provided by the embodiment of the present invention, the computer device determines, from all the first sentence vectors, the first sentence vector with the highest similarity to the second sentence vector, and takes the first house area corresponding to the first sentence vector with the highest similarity as the third house area.
That is, in this possible manner, the computer device outputs a third house area with the highest similarity, thereby ensuring the accuracy of the output result.
S150, using one of the at least one second room area overlapping with one of the third room areas as the location of the room.
It should be understood that the first location data in the embodiment of the present invention is a coordinate point, and the first house area should be described by an infinite number of coordinate points. Therefore, the first location data may not accurately describe one house area, so that the second location data may be less than a preset distance from more than one first location data, that is, more than one second house area may exist.
It is also understood that the first address information and the certified address may contain more duplicative content.
Exemplarily, if the house to be mortared and the first house area are both located in "ASDFGHJKZXCVB", the character string of the first address information of the first house area includes "ASDFGHJKZXCVB'", and the certified address also includes "ASDFGHJKZXCVB".
It is conceivable that in this case there will be a substantial overlap between the certified address of the premises to be mortared and the first address information of the first premises area, and that furthermore the certified address may be similar to more than one first address information, i.e. there may be more than one third premises area.
Therefore, in order to avoid the error which may exist when only adopting the coordinate matching or the error of only adopting the natural language to carry out the similar matching, the embodiment of the invention also carries out the secondary matching on the matching results of the two matching modes.
Specifically, the computer device determines whether there is a second room region overlapping any third room region in all the second room regions.
If the matching result based on the coordinates and the matching result based on the similarity of the natural language point to the same cell/floor, the fact that the house to be mortared is possibly existed in the cell/floor is indicated.
Therefore, in the embodiment of the present invention, the second room area overlapping with any one of the third room areas in all the second room areas is used as the area/location where the room to be mortared is located.
In addition, it may be understood that, in the embodiment of the present invention, the sequence of S130 and S140 is a content that can be set according to an actual situation, that is, the sequence of S130 and S140 and the execution sequence shown in fig. 1 may also be executed after S120 is executed, and then S140 is executed, and then S130 is executed.
In the method for positioning a house provided by the embodiment of the invention, when receiving a house mortgage request, computer equipment acquires a certificate address of a house corresponding to the house mortgage request, namely, a certificate address of a house to be mortgaged; then, converting the certificate address into a coordinate to obtain second position data of the house to be mortared; then, according to pre-stored first position data of a plurality of first house areas, taking the first house area with the distance from the second position data smaller than the preset distance as a second house area to obtain at least one second house area; using pre-stored first address information of a plurality of first house areas, and taking the first house areas with the first address information similar to the certified addresses as third house areas to obtain at least one third house area; and finally, taking the second house area superposed with the third house area as the position of the house to be mortared.
Based on the above, the embodiment of the invention adopts two modes of position matching and natural language matching to position the house corresponding to the house mortgage request, so as to provide a positioning result with higher reliability, so that a worker can determine the section/position/area of the house according to the positioning result without visiting the house offline, thereby improving the working efficiency; in addition, the evaluation flow of the house value is shortened, and the examination and approval speed of the loan amount can be increased, so that the loan experience of the client is improved.
Optionally, in a feasible manner provided by the embodiment of the present invention, specifically referring to fig. 3, a flow chart of a third method for positioning a house provided by the embodiment of the present invention is shown, where in this feasible manner, before S130, the method further includes:
s160, responding to the house area reporting request, and acquiring the address of the reported house area corresponding to the house area reporting request;
s170, converting the address of the reported house area into a coordinate to obtain first position data of the reported house area;
s180, identifying a second named entity in the address of the reported house area, and generating first address information of the reported house area according to the second named entity;
and S190, storing the first position data and the first address information of the reported house area, and taking the reported house area as the first house area.
