The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a point of interest input method according to an embodiment of the present invention, where the embodiment of the present invention is applicable to a user travel navigation situation, and the method may be executed by a point of interest input device, as shown in fig. 1, and specifically includes the following steps:
s110, acquiring an initial letter input by a user in the electronic map;
s120, obtaining user position information;
s130, inquiring candidate interest point terms from a word bank according to the initial;
s140, sorting the candidate interest point words according to the user position information.
An electronic map, i.e. a digital map, is map information digitally stored and/or called by using a computer technology, and is digitally displayed and/or interacted with a user according to map data issued by a positioning navigation satellite, the electronic map generally uses electronic map software, search application or an application program with a position sharing function to store and/or call the geographic information, for example, a Baidu map, a Gaode map, and the like, and also can be an application program which can call the electronic map, such as a browser, a popular comment or WeChat, and the like, and the application software which can directly use or call the electronic map can be installed in a vehicle-mounted terminal or a user mobile terminal. The first letter input on the electronic map refers to the first letter of the spelling of the name of the destination that the user needs to find, for example, if the user wants to find "dog cannot handle", then "GBL" (here, the first letter is not case-specific) is input in the electronic map. The user location information refers to coordinates of the geographic location where the user is currently located, which may be presented in an electronic map. A thesaurus is a database containing all geographical location names that can be recorded. The interest point is a specific geographic position in a geographic information system, and can be a house, a bridge, a bus station or a store, and the like, one interest point contains information of four aspects of name, category, coordinate, classification and the like, and can be related to other interest points related to the geographic position, and the interest point can be used for functions of place searching, position sharing, map navigation, map marking and the like. The candidate point of interest word is the name of the alternate geographic location corresponding to the initial.
When a user uses the electronic map, typing out the first letter of the spelling of the destination name to be searched in the input method, and after acquiring the first letter input by the user and the coordinate of the geographic position where the user is currently located, searching all name phrases in the geographic position name word library according to the first letter to find out the alternative geographic name matched with the first letter. According to the current geographic position coordinate of the user, all the alternative geographic names are sorted according to a preset sorting mode, the preset sorting mode can be sorting according to a region priority principle, a distance nearest principle, a scenic spot priority principle, a food and home priority principle, a network hot principle or a user frequent query principle and the like, and various sorting principles can be combined.
Furthermore, the search for the same initial in different cities is performed, the query results are generally different, for example, the user types "HLG" in the input method, if the user is in beijing, the "huilongguan" is preferentially displayed, and if the user is in western, the "hailuogougou" is preferentially displayed, so that the embodiment of the present invention performs the priority ranking according to the geographic location of the user. Furthermore, according to the 'HLG' input by the user, interest points existing in multiple cities or regions such as 'Haylongo' or 'Happy valley' can be inquired, the names of the related interest points of the current city or region are preferentially displayed according to the position of the area where the specific city of the user is located, and meanwhile, the related interest points are ranked according to the ranking principles and displayed in an interface of an input method.
In a specific embodiment, for example, the user currently drives the vehicle on the Shandong road in Tianjin, the user types "GBL" as an initial letter to query in an input method of map software of a vehicle-mounted computer or a mobile phone, and the input method retrieves specific names of a plurality of points of interest such as "dog mai", "Gongbei road" and "poon building" according to the current geographic location (i.e. the Shandong road in Tianjin) and the initial letter "GBL". The input method is characterized in that a plurality of dog no-care stores, including a dog no-care main store in Shandong roads, are sequentially sorted from near to far according to a food-accommodation priority principle, a distance nearest principle, a network hot principle and the like, and are displayed on an interactive interface of a vehicle-mounted computer.
According to the technical scheme of the embodiment of the invention, when the search of the terms of the interest points is carried out through the input method, the interest points are inquired by taking the current position information of the user as one of the reference quantities, and under the condition of only inputting the fuzzy inquiry of the initial letters, the complicated input link is simplified, the inquiry difficulty degree is reduced, the inquiry efficiency and the inquiry precision are improved, and the use experience of the user is optimized.
Example two
Fig. 2 is a flowchart of a point of interest input method according to a second embodiment of the present invention, which is further optimized based on the above-mentioned embodiments, and the embodiment of the present invention is applicable to a user travel navigation situation, and the method may be executed by a point of interest input device, as shown in fig. 2, the method may include:
s210, acquiring an initial letter input by a user in the electronic map;
s220, obtaining user position information;
s230, inquiring candidate interest point terms from a word bank according to the initial letters;
s240, determining position information of the candidate interest points according to the candidate interest point words through the electronic map;
s250, determining the relative distance between the user and the candidate interest point according to the user position information and the position information of the candidate interest point;
s260, sorting the candidate interest point words according to the relative distance.
The position information of the candidate interest points is the geographical position coordinates of the candidate interest points. The relative distance refers to the shortest actual distance between the current geographic position of the user and the geographic position of the candidate point of interest.
Candidate interest point words are obtained under the retrieval of the initial letters, respective geographic position coordinates of the candidate interest point words can be found in the electronic map according to the words, and the shortest actual distance from the candidate interest point coordinates to the current geographic position of the user is calculated. And sequencing all candidate interest point words from small to large according to the calculated distance of the path.
In one specific embodiment, for example, the user enters "MDL" in the electronic map, and the input method obtains the coordinates of the current geographic location of the user through electronic map positioning. And (3) taking the current position of the user as the center, inquiring the MDL according to a nearest distance principle, and simultaneously inquiring according to a food and host priority principle, a network hot principle and the like to obtain a plurality of 'McDonald shops' nearby. The food and lodging priority principle can also be combined with a time principle, for example, before 8 o 'clock in the evening, a food and lodging priority principle is adopted, the food and lodging place information corresponding to the first letter obtained by query is prioritized, and after 8 o' clock in the evening, an accommodation priority principle is adopted, the accommodation place information corresponding to the first letter obtained by query is prioritized. And after the geographic information of the plurality of McDonald shops is obtained, calculating the closest routes of the stores to the geographic position of the user, and sequencing the McDonald shops from near to far according to the routes.
In an alternative embodiment, the querying the candidate point of interest terms from the thesaurus according to the initial includes:
selecting a target word bank of a target region where the user is located from the candidate region word banks according to the user position information;
and querying candidate interest point terms from the target word bank.
The candidate region word bank is a word bank which divides all the interest point names according to the geographic position, and the target word bank is the region word bank which accords with the current geographic position of the user.
After the geographical position information of the user at present is obtained, the region lexicon of the place where the user is at present is selected from all the region lexicons, and the terms of the interest points in the lexicon are inquired.
In one particular embodiment, for example, the user is currently in city X, and the input method retrieves a thesaurus for city X from the electronic map. Further, the geographic position of the user is located in an area a of the city X (where the city X also governs B, C, D and other administrative districts), the input method calls a regional lexicon distinguished by the jurisdiction under the lexicon of the city X, such as an area a lexicon, an area B lexicon, an area C lexicon and the like, that is, after the user is determined to be located in the area a, the area a lexicon is called to query the initial letter input by the user.
The input method takes the position information of the current vehicle as an input item for consideration when searching the terms of the interest points, and screens the corresponding region word bank according to the position information, so that the query process is simplified, the places near the user are positioned more quickly, and the query speed and efficiency are improved.
In an optional implementation manner, before sorting the candidate point of interest words according to the user location information, the method further includes:
if the number of candidate interest point words queried from the target word bank is smaller than a number threshold, taking a parent-level region to which the target region belongs as a new target region;
and re-querying candidate interest point terms from a new target word bank of the new target area.
The number threshold is the minimum of the number of candidate interest points in the sorted list obtained by each query, for example, no less than 5 query results per query. The parent-level region is a higher-level region of a specific region to which a region thesaurus called by the current user query belongs, and can be divided according to administrative district rules, for example, the current user uses a region thesaurus in the region a, and the parent-level region in the region a is city X.
If the number of the interest point words inquired in the region lexicon related to the current geographic position is less than the number threshold, the region of the region lexicon is proved to have a high probability of not having the interest points which the user wants to inquire. Therefore, the regional thesaurus is updated to the regional thesaurus of the upper-level region.
In a specific embodiment, for example, the user is currently in the area a of city X, so the input method calls the area a thesaurus to query the initial, but the query result is less than 5, and the input method switches the area a thesaurus to the area X thesaurus to query the initial.
In the process of inquiring the interest points, the inquiry process is refined through regional classification, if the target interest points can be found by the low-level regional thesaurus, the high-level regional thesaurus is not required to be searched, if the target interest points can not be found by the low-level regional thesaurus, the search range is expanded through the high-level regional thesaurus, the inquired interest points can be further screened by combining the actual geographic position of the user, the screening process is simplified, and the inquiry accuracy is improved.
In an alternative embodiment, the ranking the candidate point of interest words according to the user location information includes:
determining the historical input frequency of the candidate interest point words by the user according to the historical input record of the user;
and sequencing the candidate interest point words according to the historical input frequency of the candidate interest point words and the user position information.
The history input record is the history record of past queries of the user, and the history input frequency is the number of times of input in the history input record.
The input method calls the input record of the user and counts the input times of all the input initials. The input times are more, which indicates that the user queries frequently, and the interest point corresponding to the initial letter is the geographical location where the user frequently visits, such as a company, a school, a home address, and the like. The input method sorts the interest points frequently inquired by the user from near to far according to the historical input frequency of the user and the current geographic position of the user, a distance nearest principle, a user frequent inquiry principle and the like.
The method for inquiring the interest points according to the retrieval frequency is beneficial to the user to inquire and navigate frequent places, and the user can conveniently inquire the high-frequency navigation places.
According to the technical scheme of the embodiment of the invention, through the mutual combination of various sorting principles, the results obtained by fuzzy query are reasonably sorted under the condition of only inputting the initial letters, a screening mode is provided from different angles, the comprehensiveness and reasonability of the query process are improved, meanwhile, the combination of various sorting principles improves the query efficiency and precision, the personalized retrieval according to the query history of the user is provided, and the use experience of the user is further improved.
