Detailed Description
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.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of an information prompting method provided in an embodiment of the present invention, which is applicable to a case where a user uses a vehicle-mounted terminal to perform a multi-condition search, in particular, a case where a plurality of search conditions conflict with each other and a result that does not completely meet all the conditions is found, where the method may be performed by an information prompting apparatus provided in an embodiment of the present invention, and the apparatus may be implemented in a software and/or hardware manner and may be generally integrated in a processor of a vehicle-mounted terminal device, for example.
As shown in fig. 1, the method of this embodiment specifically includes:
s110, acquiring multi-condition search information input by a user, and determining fixed search condition information and at least one piece of dynamic search condition information corresponding to the multi-condition search information.
The multi-condition search information refers to information including a plurality of pieces of search condition information, and the multi-condition search information is, for example, "find an avatar movie of about ten o 'clock in ten night for a ten thousand-month theater with popcorn within 5 km," "having popcorn," "the avatar movie," "about ten o' clock in night," "avatar," and "movie" are all pieces of search condition information.
Typically, the information in the multi-condition search information is more, and the user may choose to input the information in a voice manner for convenience of input. After a user clicks a search entity key or a search virtual key on the vehicle-mounted terminal, multi-condition search information is input through voice.
The multi-condition search information includes a plurality of search conditions, and specifically includes fixed search condition information and at least one dynamic search condition.
The fixed search condition information refers to a search condition corresponding to a search service provided by the vehicle-mounted terminal, and the search service provided by the vehicle-mounted terminal may be a food, a flight, a hotel, a performance, a sight spot, a movie, a ticket booking, and the like. The fixed search condition information is also different for different search services, for example, the fixed search condition information of the gourmet search service may be "address location information" + "gourmet", the fixed search condition information of the ticket booking service may be "origin" + "destination" + "ticket booking type", and the like.
The dynamic search condition information refers to a search condition that specifically defines fixed search condition information, and the dynamic search condition information does not include range-defining information and location-defining information, for example, the fixed search condition information of the gourmet search service may be "address location information" + "gourmet", and the dynamic search condition information thereof may be gourmet type, average person consumption, restaurant environment, and the like.
After acquiring the multi-condition search information input by the user through voice, the vehicle-mounted terminal performs voice recognition on the multi-condition search information to obtain text information corresponding to the multi-condition search information, and then analyzes the text.
As an optional implementation manner of this embodiment, the determining of the fixed search condition information and the at least one piece of dynamic search condition information corresponding to the multi-condition search information may specifically be:
and matching the multi-condition search information input by the user with a preset fixed search condition information example and a preset dynamic search condition information example to obtain fixed search condition information and at least one piece of dynamic search condition information corresponding to the multi-condition search information.
In the vehicle-mounted terminal, a fixed search condition information example and a dynamic search condition information example respectively corresponding to each type of search service are stored, and the fixed search condition information example and the dynamic search condition information example may be specifically stored in a form of a data table.
After acquiring the multi-condition search information input by the user, the vehicle-mounted terminal firstly determines a search service type corresponding to the multi-condition search information, then acquires a fixed search condition information example table and a dynamic search condition information example table corresponding to the search service type, and respectively matches the multi-condition search information with the fixed search condition information example and the dynamic search condition information example to obtain the fixed search condition information and at least one piece of dynamic search condition information corresponding to the multi-condition search information.
For example, based on big data analysis, the dynamic search condition information which does not exist in the current dynamic search condition information example table but is frequently used by a user for a certain search service in the recent period of time is counted and added to the corresponding dynamic search condition information example table as the newly added dynamic search condition information corresponding to the search service.
It should be noted that the multi-condition search information may further include invalid search information, and in this embodiment, the invalid search information specifically refers to search information that cannot be successfully matched with the fixed search condition information example table and the dynamic search condition information example table, and is treated as invalid search information. For example, the conditional search information is "an avatar movie with popcorn in 5 km/so at ten o 'clock night" in which "5 km/so" and "movie" are successfully matched with the fixed search condition information example table, "an avatar movie" and "ten o' clock night" and "avatar movie" are successfully matched with the dynamic search condition information example table, and "popcorn is" is not successfully matched with the fixed search condition information example table and the dynamic search condition information example table, so "popcorn is" an invalid search condition.
The "matching success" may be an accurate matching success, or may be a fuzzy matching success, which is not specifically limited in this embodiment.
Further, if the fixed search condition information corresponding to a certain query service includes geographical location information, for example, "xx within kilometer" or "xx nearby", and the multi-condition search information input by the user does not include geographical location information, the current geographical location information of the in-vehicle terminal is acquired through the positioning device, and the preset search condition information "set within a distance (for example, 5 kilometers) with the current geographical location information as the center" is taken as the fixed search condition information corresponding to the geographical location information.
And S120, carrying out global search according to the fixed search condition information to obtain a total search result set.
After the fixed search condition information is determined by the vehicle-mounted terminal, global search is carried out based on the fixed search condition information to obtain a total search result set. This total search result set is the basis for providing accurate search results to the user.
Typically, if any result cannot be searched according to the fixed search condition information, the fixed search condition information may be re-searched after being expanded in range. For example, the fixed search condition information is "5 km" + "food", and if any result cannot be searched, the range of "5 km" can be expanded. Meanwhile, a range expansion extreme value can be preset, for example, 20 km, when any result cannot be searched after the fixed search condition information is modified to 20 km + food, the result is considered to be not searched, and further, unsearched data is returned to the user.
S130, screening is carried out on the total search result set according to each piece of dynamic search condition information, and a single dynamic condition hit result set corresponding to each piece of dynamic search condition information is obtained.
And after the total search result set is obtained, screening each piece of dynamic search condition information in the total search result set respectively to obtain each single dynamic condition hit result set corresponding to each piece of dynamic search condition information respectively. The single dynamic condition hit result set is a result set obtained by performing global search according to the fixed search condition information and one piece of dynamic search condition information.
Specifically, how many pieces of dynamic search condition information can be determined according to the multi-condition search information, and how many single dynamic condition hit result sets can be obtained.
And S140, providing accurate search results corresponding to the multi-condition search information and dynamic search condition information corresponding to the accurate search results for the user according to the single dynamic condition hit result set corresponding to each piece of dynamic search condition information.
And combining each single dynamic condition hit result set to generate an accurate search result corresponding to the multi-condition search information for the user, and providing each piece of dynamic search condition information corresponding to the accurate search result for the user while providing the accurate search result, namely which pieces of dynamic search condition information are hit by the accurate search result. Specifically, the accurate search result and the dynamic search condition information corresponding to the accurate search result can be notified to the user in a voice broadcast and/or text display mode.
If each single dynamic condition hit result set includes the same search result, the search result is provided to the user as an accurate search result, and each dynamic condition information is also provided to the user. For example, the voice broadcast "searches for you for XX1, XX1 attribute 1, XX1 attribute 2, … …, XX1 attribute n 1", and XX1 attribute 1-XX1 attribute n1 is dynamic search condition information hit by XX1, that is, all dynamic search condition information corresponding to the multiple-condition search information.
If no search result appears in each single dynamic condition hit result set, one search result appearing in most single dynamic condition hit result sets is provided to the user as an accurate search result, and meanwhile, dynamic search condition information conforming to the search result can be provided to the user. For example, the voice broadcast "does not search for a completely matched result, it is recommended to you that the attribute 1 of XX2, XX2, the attribute 2 of XX2, … …, and the attribute n2 of XX2, and the attribute 1 of XX 2-XX 2, n2, are dynamic search condition information hit by XX2, that is, partial dynamic search condition information corresponding to the multiple pieces of condition search information.
According to the technical scheme provided by the embodiment of the invention, when multi-condition search information input by a user is received, the multi-condition search conditions are analyzed to obtain fixed search conditions and various dynamic search conditions, a global search is firstly carried out based on the fixed search conditions to obtain a total search result set, then the total search result set is respectively searched based on each dynamic state to obtain a single dynamic condition hit result set respectively corresponding to each dynamic search condition, and then the accurate search results corresponding to the multi-condition search information and the dynamic search condition information corresponding to the accurate search results are provided for the user by combining the single dynamic condition hit result sets. Thus, the feedback information for the multi-conditional search information of the user includes not only the search result but also dynamic search condition information corresponding to the search result, that is, a dynamic search condition hit by the search result provided by the system. Particularly, when a plurality of search conditions input by the user are in conflict and results which completely meet the conditions cannot be searched, the user can clearly know which search conditions the search results provided by the system are based on for the user to refer to, and meanwhile, the multi-condition search experience of the user is also improved.
As a specific implementation manner of this embodiment, after determining the fixed search condition information and the at least one piece of dynamic search condition information corresponding to the multiple pieces of conditional search information, the method further includes: determining the total amount of the dynamic search condition information; further, S140 may be specifically:
and providing an accurate search result corresponding to the multi-condition search information and the dynamic search condition information corresponding to the accurate search result for the user according to a single dynamic condition hit result set corresponding to each piece of dynamic search condition information and the total amount of the dynamic search condition information.
After determining each piece of dynamic search condition information corresponding to the multi-condition search information, the vehicle-mounted terminal counts the total number m of all pieces of dynamic search condition information, and then when determining an accurate search result corresponding to the multi-condition search information according to each single dynamic condition hit result set, the vehicle-mounted terminal can refer to the total number m.
If m single dynamic conditional hit result sets all comprise one search result, determining that the search result is a search result completely corresponding to the multi-conditional search information; if only r (r < m) single dynamic conditional hit result sets each include a search result, the smaller the difference between r and m, the closer the search result can be determined to the user's search requirements.
Example two
Fig. 2 is a flowchart of an information prompting method provided in a second embodiment of the present invention, which is embodied on the basis of the above embodiments, wherein the providing, for a user, an accurate search result corresponding to multi-condition search information and dynamic search condition information corresponding to the accurate search result according to a single dynamic condition hit result set corresponding to each piece of dynamic search condition information and a total number of pieces of dynamic search condition information includes:
merging single dynamic condition search result sets respectively corresponding to the dynamic search condition information to obtain a dynamic condition hit condition general table, wherein the dynamic condition hit condition general table comprises the dynamic search condition information hit by each search result and the number of the hit dynamic search condition information;
and providing an accurate search result corresponding to the multi-condition search information and dynamic search condition information corresponding to the accurate search result for the user according to the total amount of the dynamic search condition information and the dynamic condition hit condition summary table.
As shown in fig. 2, the method of this embodiment specifically includes:
s210, acquiring multi-condition search information input by a user, and determining fixed search condition information and at least one piece of dynamic search condition information corresponding to the multi-condition search information.
For example, the multi-condition search information input by the user is "find a hot pot restaurant with a parking lot below 80 everybody within 5 km nearby", the vehicle-mounted terminal receives and determines the food inquiry service selected by the user, further obtains a fixed search condition information example and a dynamic search condition information example corresponding to the food inquiry service, and matches the fixed search condition information and the dynamic search condition information with the multi-condition search information, so as to determine that the fixed search condition information is "5 km nearby food", and the dynamic search condition information is "everybody is less than 80", "parking lot", and "hot pot".
And S220, determining the total amount of the dynamic search condition information.
In the above example, the total number of pieces of dynamic search condition information is 3.
And S230, carrying out global search according to the fixed search condition information to obtain a total search result set.
And carrying out global search according to the fixed search condition information '5 km nearby food', and obtaining the following total search result set: { spicy attraction, submarine fishing, Wangxiangyuan, Nanlaishun, Quanjude, Xiaojun Ganjiang, Kendeji, Laobian dumpling }.
S240, screening is carried out on the total search result set according to each piece of dynamic search condition information, and a single dynamic condition hit result set corresponding to each piece of dynamic search condition information is obtained.
Screening in a total search result set { spicy allure, seabed fishing, Hoxiangyuan, Nanlaishun, Quanjude, Xiaocounty liver string incense, Kendeji, and Laobian dumpling } according to dynamic search condition information 'everybody is less than 80', and obtaining a single dynamic condition hit result set corresponding to the dynamic search condition information 'everybody is less than 80': { spicy attraction, Wanxiangyuan, Nanlaishun, Xiaoshire Gansu, Kendeji, Laobiandumpling }.
Screening in a total search result set { spicy luring, seabed fishing, Hope Hunan, Nanlaishun, Quanjude, Xiaoprefecture liver string incense, Kendeji, old dumpling } according to dynamic search condition information 'parking lot', to obtain a single dynamic condition hit result set corresponding to the dynamic search condition information 'parking lot': { spicy attraction, submarine fishing, south laishun, all-poly de }.
According to the dynamic search condition information 'hot pot', screening is carried out in a total search result set { spicy hot temptation, seabed fishing, Wanxiangyuan, Nanlaishun, Quanjude, Xiaojun liver cluster incense, Kendeji and Laobing } to obtain a single dynamic condition hit result set corresponding to the dynamic search condition information 'hot pot': { Sudoku, Nanlaishun, Xiaoshire, Gancouxiang }.
And S250, merging the single dynamic condition search result sets respectively corresponding to the dynamic search condition information to obtain a dynamic condition hit condition general table, wherein the dynamic condition hit condition general table comprises the dynamic search condition information hit by each search result and the number of the hit dynamic search condition information.
Continuing with the foregoing example, after merging the single dynamic condition search result sets respectively corresponding to the dynamic search condition information, a dynamic condition hit condition summary table is obtained:
| name of food | Number of hit dynamic search condition information | Hit dynamic search criteria information |
| Temptation of spicy hot | 2 | Less than 80 persons in the parking lot |
| Fishing on the seabed | 2 | Parking lot and chafing dish |
| Wangxiangyuan | 1 | All people are less than 80 |
| All directions of south China | 3 | Less than 80 per capita, parking lot and chafing dish |
| All poly (ethylene-co-propylene-co-butylene) | 1 | Parking lot |
| Xiaoprefecture liver string incense | 2 | Less than 80 per capita, chafing dish |
| Kendyl | 1 | All people are less than 80 |
| Old dumpling | 1 | All people are less than 80 |
And S260, providing an accurate search result corresponding to the multi-condition search information and dynamic search condition information corresponding to the accurate search result for the user according to the total amount of the dynamic search condition information and the dynamic condition hit condition summary table.
The closer the number of dynamic search condition information hits in the search result and the total number of dynamic search condition information are, the more matched the search result and the multi-condition search information are. When the number of dynamic search condition information hit by the search result is equal to the total number of dynamic search condition information, the search result completely satisfies the multi-condition search information.
Specifically, if at least one first target search result exists in the dynamic condition hit condition summary table, and the number of pieces of dynamic search condition information hit by the first target search result is equal to the total number of pieces of dynamic search condition information, the first target search result is used as an accurate search result corresponding to the multi-condition search information, and the first target search result and the dynamic search condition information hit by the first target search result are provided to the user.
As shown in the dynamic condition hit condition summary table, if the number of hit dynamic search condition information of "nan lain" is equal to the total number of dynamic search condition information, and is all 3, "nan lain" is the first target search result. Moreover, there are no other first target search results, that is, the number of the first target search results is 1, and then "nan laishun" is provided to the user as an accurate search result, and at the same time, the dynamic search condition information hit by "nan laishun" is also provided to the user.
Specifically, the accurate search result and the dynamic search condition information corresponding to the accurate search result can be notified to the user through voice broadcast and text display, for example, the accurate search result "south comes in the same order" and the hit dynamic search condition information "everyone is less than 80, the parking lot and the hot pot" are displayed on the screen of the vehicle-mounted terminal, and "you have searched for" south comes in the same order "through voice broadcast, the hot pot shop, everyone has consumed less than 80, and there is a parking lot nearby.
Further, the distance of the accurate search result from the current position can be provided to the user at the same time.
If the first target search result does not exist in the dynamic condition hit condition general table, taking a second target search result existing in the dynamic condition hit condition general table as an accurate search result corresponding to the multi-condition search information, and providing the second target search result and the dynamic search condition information hit by the second target search result to the user; and the number of the dynamic search condition information hit by the second target search result is less than the total number of the dynamic search condition information.
Assuming that, in the dynamic condition hit condition summary table, the number of hit dynamic search condition information of "nan lain" is also 2, there is no search result whose number of hit dynamic search condition information is equal to the total number of dynamic search condition information, and then a part of the search results in the dynamic condition hit condition summary table is selected as a second target search result to be provided to the user, or all the search results in the dynamic condition hit condition summary table are provided to the user as the second target search result, and all the search results in the dynamic condition hit condition summary table are provided to the user as the second target search result for explanation as follows.
Continuing with the above example, through the form of voice broadcast and text display, the following related information of the second target search result is provided to the user:
| name of food | Dynamic search of hitsInformation on cable conditions | Distance between two adjacent plates |
| Temptation of spicy hot | Less than 80 persons in the parking lot | 2.3km |
| Fishing on the seabed | Parking lot and chafing dish | 2.0km |
| Wangxiangyuan | All people are less than 80 | 1.3km |
| All directions of south China | Less than 80 per capita, chafing dish | 0.9km |
| All poly (ethylene-co-propylene-co-butylene) | Parking lot | 0.1km |
| Xiaoprefecture liver string incense | Less than 80 per capita, chafing dish | 2.5km |
| Kendyl | All people are less than 80 | 0.3km |
| Old dumpling | All people are less than 80 | 1.6km |
For example, a voice broadcast "no completely matching results are searched, and you are now recommended: spicy and hot temptation, people consume less than 80, nearby parking lots are 2.3km away from you; taking out the information from the seabed, a hot pot restaurant, a parking lot which is 2.0km … …' away from the user, and circulating and rolling the recommendation information through the vehicle-mounted terminal interface.
As an optional implementation manner of this embodiment, S260 may be specifically referred to as S261-S262.
And S261, judging whether at least one first target search result exists in the dynamic condition hit condition summary table, if so, executing S262, and if not, executing S263.
And S262, taking the first target search result as an accurate search result corresponding to the multi-condition search information, and providing the first target search result and the dynamic search condition information hit by the first target search result to the user.
And S263, taking all the search results in the dynamic condition hit condition summary table as second target search results, and providing the second target search results and the dynamic search condition information hit by the second target search results to the user.
For the sake of brevity, the present embodiment is not described in detail herein.
