Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 illustrates a flow diagram of an information search method provided in accordance with some embodiments of the present invention. Referring to fig. 1, the information searching method includes steps S110, S120, S130 and S140, and may be applied to a mobile terminal, which is executed by the mobile terminal. The information search method will be described in detail below with reference to fig. 1.
Referring to fig. 1, in step S110, a search term input by a user is received.
In an example embodiment, at an information search interface, a search term input by a user is received. The search terms do not necessarily correspond exactly to the specific vocabulary used in the information records that are desired to be searched. For example, when searching for a chat record, the main content of the chat record that the user wants to search for is "please eat you in the evening today", but the specific content sent by the chat is "please eat tonight, go XX restaurant", and the search word input by the user may be "eat" or "restaurant".
In step S120, at least one candidate search word is filtered out from a preset candidate word library based on the search word.
In an example embodiment, based on the search word, a predetermined number of alternative search words are screened out from a preset alternative word library and displayed for the user to select. For example, the search word input by the user is "eat", and 3 candidate search words "restaurant", and "restaurant" are screened from a preset candidate word bank and displayed.
In an example embodiment, screening out at least one alternative search word from a preset alternative word library based on the search word comprises: determining the similarity between the search word and each alternative search word in a preset alternative word bank; sequencing all the alternative search terms according to the similarity; and based on the sorted results, at least one alternative search word is selected from the alternative search words in the descending order. For example, determining the similarity between the search word "eat" and each alternative search word in the alternative word bank; sorting the alternative search words according to the similarity, wherein the greater the similarity is, the more similar the word senses of the alternative search words and the search words are; and selecting 3 candidate search words "restaurant", "restaurant" and "restaurant" which are closest to the word meaning of "eating" from the candidate word library.
In an example embodiment, the method for determining similarity between a search word and each candidate search word in a preset candidate word bank specifically includes: calculating the distance between the word vector of the search word and the word vector of each alternative search word in a preset alternative word bank; based on the distance, a similarity of the search term to each of the candidate search terms is determined. The closer the word vector distance between the search word and the alternative search word is, the higher the corresponding similarity is.
It should be noted that the distance between the word vectors may be a hamming distance, a euclidean distance, or a cosine distance, but the distance in the exemplary embodiment of the present invention is not limited thereto, and for example, the distance may also be a mahalanobis distance, a manhattan distance, or the like.
In an example embodiment, the word vector model is trained in advance to compute a word vector for the search word and the candidate search word. For example, in the word vector model, commonly used word2vec forms a word vector model, including a CBOW model and a Skip-Gram model. The CBOW model is trained by inputting a word vector corresponding to a word related to the context of a certain characteristic word and outputting the word vector of the specific word. The Skip-Gram model is trained by inputting a word vector of a specific word and outputting a context word vector corresponding to the specific word.
In step S130, a target candidate search term selected by the user from the at least one candidate search term is received.
In an example embodiment, an alternative search word selected by the user from the at least one alternative search word is determined as a target alternative search word, and the target alternative search word is used in step S140. And after the selection operation of the user, the mobile terminal receives the target alternative search word selected by the user. For example, three alternative search terms "restaurant", "restaurant" and "restaurant" are presented for selection by the user, the user selects the alternative search term "restaurant" as the target alternative search term, and the mobile terminal receives the target alternative search term "restaurant".
In an example embodiment, the manner for the user to select the target candidate search term from the at least one candidate search term may be to click a certain candidate search term, or to drag a certain candidate search term to a preset area, which is not particularly limited in the present invention.
In step S140, the corresponding information record is searched for based on the search term and the target candidate search term.
In an example embodiment, a search is conducted for information records that contain one or more of a search term and a target candidate search term. The information record comprises at least one of the search term and the target candidate search term. The searching method may be full word matching, or may be searching after segmenting words in the search sentence, and the present invention is not limited to this. For example, the search term is "eat", the target candidate search term is "restaurant" or "restaurant", and the chat log including the search term and one or more of the target candidate search terms is searched for, resulting in a chat log "this evening visitor, go XX restaurant", which includes the candidate search term "restaurant".
It should be noted that, in an example embodiment, when the mobile terminal generates an information record, the background of the mobile terminal may record the position where the user was when the information record was generated as the position attribute of the information record. For example, when a user chats, the background takes the position of the user when sending and receiving the chat information as the position attribute of the chat information and stores the position attribute.
In another exemplary embodiment, after the mobile terminal searches for the corresponding information record based on the search term and the target candidate search term, the following process may be further performed: receiving a first selection input of a user for a location; determining a first target location selected by a user in response to a first selection input; based on the first target position, a target information record corresponding to the first target position is determined from the searched information records. For example, after the mobile terminal searches the corresponding information record based on the search term and the target candidate search term, the mobile terminal inquires whether the user uses a map, and if the user uses the map, a place is selected from the map, and the place is the position of the information record generated in the user memory. Responding to a position selection instruction input by a user, and determining a place selected by the user; based on the location, an information record corresponding to the location is determined from the searched information records.
In another example embodiment, determining a target information record corresponding to a first target location from the searched information records based on the first target location comprises: determining a search range centered on the first target position based on the first target position; and determining the information record determined to fall into the search range in the searched information records as the target information record based on the search range. The shape of the search range can be circular or square, the size of the search range can be set by user-definition according to the needs of the user, and the invention is not limited to this.
In yet another example embodiment, searching for corresponding information records based on a search term and a target alternative search term includes: receiving a second selection input of the user for the position; determining a second target location selected by the user in response to the second selection input; and searching corresponding information records based on the search words, the target candidate search words and the second target position. For example, the mobile terminal receives a target location selected by the user on the map, which is the second target location. For example, receiving a search word "eat" input by a user, screening 3 candidate search words "restaurant", "restaurant" and "restaurant" from a preset candidate word library, displaying the candidate search words, taking the "restaurant" selected by the user as a target candidate search word, determining that the user selects a location "AB station" in response to a position selection instruction input by the user, wherein the preset search range is a circle and has a radius of 100 meters, simultaneously screening information records according to the "eating", "restaurant" and the location "AB station", and searching for the information records which accord with the search range which contains one or more of the search word and the target candidate search word and also falls into the "AB station" as the center.
It should be noted that, in the exemplary embodiment, the two ways of searching for information records according to the search term and the target candidate search term and the information records according to the location may be performed separately, and if the information records are searched comprehensively through the two ways, the order of the two ways may also be variable. For example, the corresponding information record is searched only according to the location; searching corresponding information records only according to the search words and the target alternative search words; receiving a place selected by a user, searching information records corresponding to the place, and searching the information records corresponding to the search terms and the target alternative search terms from the information records corresponding to the place according to the search terms and the target alternative search terms; searching corresponding information records according to the search words and the target alternative search words, receiving a place selected by a user, and searching the information records corresponding to the place from the information records corresponding to the search words and the target alternative search words.
According to the information searching method in the example embodiment of fig. 1, on one hand, a search word input by a user is received, and the search word for searching information records can be obtained; on the other hand, based on the search words, at least one alternative search word is screened out from a preset alternative word library, and alternative search words with similar meanings to the search words can be displayed for the user to select; on the other hand, receiving a target alternative search word selected by a user from at least one alternative search word, and obtaining the target alternative search word selected by the user; in another aspect, based on the search term and the information record corresponding to the target alternative search term search, search failure caused by inaccuracy of the search term input by the user can be reduced, and therefore the efficiency of information search is improved.
Fig. 2 is a schematic diagram illustrating an application scenario of an information search method according to an embodiment of the present invention.
Referring to fig. 2, a search word 210 in a text input box of a chat log search interface on a mobile terminal is "eat". Based on the search term 210, the system recommends three alternative search terms 220, "restaurant," restaurant, "and" restaurant. A map is presented under the alternative search terms 220 of the interface, and the location 230 is the location where the user sends information in the memory selected on the map.
