The present disclosure relates to a field of an artificial intelligence technology, and in particular, to fields of NLP (Natural Language Processing) and knowledge graph.
NLP (Natural Language Processing) refers to causing a computer to: receive a user's input in a form of a natural language, internally perform a series of operations such as processing, calculation, etc. through an algorithm defined by human, so as to simulate a human understanding of the natural language, and return a desired result to the user. A purpose of the NLP is to use the computer instead of the human to process large-scale natural language information. For example, a recognition of a location information in a text may be implemented based on the NLP.
The present disclosure provides a method of determining a location information, an electronic device, and a storage medium.
According to an aspect of the present disclosure, a method of determining a location information is provided, including: determining at least one location chain corresponding to a location information in a text to be recognized, wherein each of the at least one location chain includes a plurality of chain nodes cascaded according to a subordination relationship, and each level of chain node represents a current level name corresponding to the location information; and determining, from the at least one location chain, a target location chain having a greatest degree of relevance to the text to be recognized, according to a feature word indicating a location attribute in the text to be recognized.
According to an aspect of the present disclosure, an electronic device is provided, including: at least one processor; and a memory communicatively connected to the at least one processor, wherein the memory stores instructions executable by the at least one processor, and the instructions, when executed by the at least one processor, cause the at least one processor to implement the method of determining the location information as described above.
According to an aspect of the present disclosure, a non-transitory computer-readable storage medium having computer instructions therein is provided, and the computer instructions are configured to cause a computer system to implement the method of determining the location information as described above.
It should be understood that content described in this section is not intended to identify key or important features in embodiments of the present disclosure, nor is it intended to limit the scope of the present disclosure. Other features of the present disclosure will be easily understood through the following description.
The accompanying drawings are used for better understanding of the solution and do not constitute a limitation to the present disclosure, wherein:
Exemplary embodiments of the present disclosure will be described below with reference to the accompanying drawings, which include various details of embodiments of the present disclosure to facilitate understanding and should be considered as merely exemplary. Therefore, those of ordinary skilled in the art should realize that various changes and modifications may be made to embodiments described herein without departing from the scope and spirit of the present disclosure. Likewise, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.
In the technical solution of the present disclosure, the collection, storage, use, processing, transmission, provision, disclosure and application of the location information involved are all in compliance with the provisions of relevant laws and regulations, and necessary confidentiality measures have been taken, and it does not violate public order and good morals. In the technical solution of the present disclosure, before obtaining or collecting the user's personal information, the user's authorization or consent is obtained.
In embodiments of the present disclosure, X represents a location information, which may be specifically expressed as A, B, C or other locations. X′ represents a name of a superior administrative region of X; and X″ represents a name of a superior administrative region of X′. For example, when X is a name of a district (county)-level administrative region, X′ is a name of a municipal-level administrative region; when X is a name of a municipal-level administrative region, X′ is a name of a provincial-level administrative region; when X is a name of a provincial-level administrative region, X′ is a name of a country, and the like. X may represent an alias of Province X, City X, District (County) X, or the like; Xname_1, Xname_2, . . . , Xname_n and so on may represent aliases of X; and Xbrother_1, Xbrother_2, . . . , Xbrother_n and so on may represent names of administrative regions at the same level as X, where n is a positive integer. For example, A and Aname_1 may be aliases of City A, Abrother_1 may be a name of another prefecture-level city in a province corresponding to City A. When X may correspond to a plurality of different regions, names of superior administrative regions of X in different regions may be represented by Xadm_1, Xadm_2, . . . , Xadm_n. For example, if X may correspond to three different regions belonging to different administrative regions, then X in the three different regions may be expressed as “District X-City Xadm_1′”, “District X-City Xadm_2′-Province Xadm_2″”, “City X-Province Xadm_3′”.
Generally, for a recognition of a location information in a text, it is only implemented to recognize a level of “City”, and a normalization and a complementation are not performed for a location. Moreover, a character string matching is generally used to process location ambiguity, resulting in a location recognition error and a normalization error.

In operation S210, at least one location chain corresponding to a location information in a text to be recognized is determined. Each location chain includes a plurality of chain nodes cascaded according to a subordination relationship, and each level of chain node represents a current level name corresponding to the location information.
In operation S220, a target location chain having a greatest degree of relevance to the text to be recognized is determined from the at least one location chain, according to a feature word indicating a location attribute in the text to be recognized.
According to embodiments of the present disclosure, the text to be recognized may be various types of text, including a web page text or a document text containing the location information. The location chain may be a location chain formed by cascading administrative regions. Each chain node may represent a name of a level of administrative region.

According to embodiments of the present disclosure, for a location information in the text to be recognized, at least one place name information related to the location information may be obtained correspondingly. In a case of obtaining a plurality of place name information that may not be associated with each other, an another feature word indicating the location attribute in the text to be recognized may be further recognized, so as to further select and determine a unique place name information having a greatest degree of relevance to the text to be recognized according to the another feature word. In a case that only one place name information is obtained, an accuracy of the obtained place name information may be further determined according to a feature word in the text to be recognized.
According to embodiments of the present disclosure, the determined place name information may be a location chain containing names of various levels of administrative regions corresponding to the location information, which may be specifically expressed in a form of: District (County) XX, City XX, Province XX.
Through above-described embodiments of the present disclosure, a disambiguation may be performed on the at least one location chain corresponding to the location information in the text to be recognized according to the feature word indicating the location attribute in the text to be recognized, so as to determine the target location chain having a greatest degree of relevance to the text to be recognized, so that the accuracy of the determined target location chain may be effectively improved.
The method shown in
According to embodiments of the present disclosure, as shown in
In operation S310, a text to be recognized is input into a location recognition model to obtain a location information in the text to be recognized. The location recognition model is determined based on a named entity recognition technology.
In operation S210, at least one location chain corresponding to the location information in the text to be recognized is determined. Each location chain includes a plurality of chain nodes cascaded according to a subordination relationship, and each level of chain node represents a current level name corresponding to the location information.
In operation S220, a target location chain having a greatest degree of relevance to the text to be recognized is determined from the at least one location chain, according to a feature word indicating a location attribute in the text to be recognized.
According to embodiments of the present disclosure, for example, the named entity recognition technology may be used to recognize the location information in the text to be recognized. For example, a location recognition model with a named entity recognition function may be trained based on BiLstm-CRF (a named entity recognition model), so that the location information in the text to be recognized may be recognized using the location recognition model. The location recognition model may be trained by collecting a text corpus containing the location information and annotating a location entity in the text corpus.
Through above-described embodiments of the present disclosure, the recognition of the location information using the named entity recognition technology may be implemented to effectively improve the accuracy and integrity of the recognized location information.
According to embodiments of the present disclosure, as shown in
In operation S310, a text to be recognized is input into a location recognition model to obtain a location information in the text to be recognized. The location recognition model is determined based on the named entity recognition technology.
In operation S320, when the location information in the text to be recognized is an alias, an official name corresponding to the alias is determined according to an alias dictionary. The alias dictionary contains a mapping relationship between the alias and the official name indicating the same location information. The location information in the text to be recognized may be re-determined according to the official name.
In operation S210, at least one location chain corresponding to the location information in the text to be recognized is determined. Each location chain includes a plurality of chain nodes cascaded according to a subordination relationship, and each level of chain node represents a current level name corresponding to the location information.
In operation S220, a target location chain having a greatest degree of relevance to the text to be recognized is determined from the at least one location chain according to a feature word indicating a location attribute in the text to be recognized.
According to embodiments of the present disclosure, the official name may be an ancient place name and/or a modern place name. The ancient place name may indicate an ancient official name, and the modern place name may indicate a modern official name. The alias dictionary may contain, for example, at least one selected from: a mapping relationship between an ancient place name and a modern place name, a mapping relationship between a network alias and an ancient place name, a mapping relationship between a network alias and a modern place name, or a mapping relationship between a modern alias and a modern place name. For example, an alias of “District A” includes “A”, and aliases of “City B” include “B” and “Bname_1”, a mapping relationship between “A” and “District A”, a mapping relationship between “B” and “City B”, and a mapping relationship between “Bname_1” and “City B” may be established.
It should be noted that the alias dictionary may be updated online or offline, and may also be used online or offline.
According to embodiments of the present disclosure, as the location information in the text to be recognized is generally not directly expressed as a standard name of a corresponding district or city, after the location information in the text to be recognized is recognized using the location recognition model, an official name of the recognized location information may be further determined according to the alias dictionary. For example, a text to be recognized contains location information “Aadm_1′” and “A”. Each location information may be analyzed according to the alias dictionary. For example, it may be determined that the text to be recognized contains “City Aadm_1′”, “District A”, “City A”, etc. When the recognized location information is an alias of a location, an official name of the recognized location information may be further determined according to the alias dictionary. For example, if a location information recognized from another text to be recognized includes “Bname_1”, then it may be determined that an official name corresponding to the location information is “B”, and it may be re-determined that the location information in the text to be recognized includes “B”.
Through above-described embodiments of the present disclosure, the alias dictionary is introduced to recognize the alias information, which may effectively improve the integrity of the recognition result.
According to embodiments of the present disclosure, determining at least one location chain corresponding to the location information in the text to be recognized includes acquiring an administrative region knowledge graph. The administrative region knowledge graph is constructed according to administrative regions. The at least one location chain corresponding to the location information may be determined according to the administrative region knowledge graph.
As shown in
According to embodiments of the present disclosure, for the location information determined from the text to be recognized, at least one related location chain may be determined from the administrative region knowledge graph. For example, a location chain of “City B-Province B′” may be acquired according to “B”. A plurality of location chains such as “District A-City Aadm_1′”, “District A-City Aadm_2′-Province Aadm_2∴”, “City A-Province Aadm_3′” etc. may be acquired according to “A”. If the “Aadm_1′”, “Aadm_2″”, “Aadm_2′” and other information do not exist in the text, an automatic complementation may be performed with reference to the administrative region knowledge graph, so that a representation of a result is normalized, that is, a location in the standard form of District/County-City-Province is output.
Through above-described embodiments of the present disclosure, an introduction of the administrative region knowledge graph may cause a more normalized and standardized representation of a recall result, and further improve an integrity of the recall result.
According to embodiments of the present disclosure, determining the target location chain having a greatest degree of relevance to the text to be recognized from the at least one location chain according to the feature word indicating the location attribute in the text to be recognized may include: determining, from the at least one location chain, a location chain containing the feature word as the target location chain, in response to the feature word being consistent with a chain node in the at least one location chain.
According to embodiments of the present disclosure, each location chain may be defined as a multi-dimensional vector. For example, according to a representation form of “District/County-City-Province-Country”, the location chain may be defined as a four-dimensional vector. A location information in the text to be recognized may be recognized, and then a value in the four-dimensional vector corresponding to a chain node in the location chain representing the location information in the text to be recognized is assigned 1, and a value in the four-dimensional vector corresponding to a remaining chain node is assigned 0, the target location chain may be determined according to the number of value 1 in the four-dimensional vector.
For example, if the text to be recognized contains a location information “A”, an initial value of the four-dimensional vector may be determined as [1,0,0,0] based on the location information. For the location information “A” in the text to be recognized, three location chains, including “District A-City Aadm_2′-Province Aadm_2″”, “District A-City Aadm_1′” and “City A-Province Aadm_3′”, may be determined. If the text to be recognized further contains a location information “Aadm_1′” which may be used as a feature word for a further determination, then the four-dimensional vectors of the above-mentioned three location chains corresponding to the text to be recognized may be [1,0,0,0], [1,1,0,0], [0,1,0,0], respectively. According to the number of value 1 in the four-dimensional vector, it may be determined that the target location chain having a greatest degree of relevance to the text to be recognized is “District A-City Aadm_1′”.
Through above-described embodiments of the present disclosure, a feature disambiguation method is provided, and the target location chain obtained based on the feature disambiguation has a higher accuracy.
According to embodiments of the present disclosure, determining the target location chain having a greatest degree of relevance to the text to be recognized from the at least one location chain according to the feature word indicating the location attribute in the text to be recognized may include: in response to feature words being consistent with a plurality of chain nodes belonging to at least two location chains among the at least one location chain, determining, from the at least two location chains, a location chain with a greatest number of feature words as the target location chain.
According to embodiments of the present disclosure, for example, representation results of the four-dimensional vectors related to the location information in the text to be recognized that is obtained based on the feature word in the text to be recognized may include [1,1,1,0] and [1,1,0,0]. Sizes of character strings corresponding to the two vectors may be compared, and a location chain represented by the four-dimensional vector corresponding to the character string with a larger size may be determined as the target location chain.
For example, if the text to be recognized contains “A” and “Aadm_1′”, results of “District A-City Aadm_1′” and “District A-City Aadm_1′-Aadm_1′” may be obtained, and the representations of the four-dimensional vectors corresponding to the two may be, for example, [1,1,0,0] and [1,1,1,0]. According to the sizes of character strings, the latter, that is, “District A-City Aadm_1′-Aadm_1′”, may be determined as the output target location chain.
For example, if the text to be recognized contains “A”, “Aadm_1′”, “Aadm_2″” and “Aadm_2″”, two results of “District A-City Aadm_1′-Aadm_1′” and “District A-City Aadm_2′-Province Aadm_2″” may be obtained. As representations of four-dimensional vectors corresponding to the two location chains are both [1,1,1,0], a disambiguation of the plurality of location chains may be further performed in combination with other features.
Through above-described embodiments of the present disclosure, another feature disambiguation method is provided, and the target location chain obtained based on the feature disambiguation has a higher accuracy.
According to embodiments of the present disclosure, determining the target location chain having a greatest degree of relevance to the text to be recognized from the at least one location chain according to the feature word indicating the location attribute in the text to be recognized may include: determining a degree of association between a chain node in the at least one location chain and the feature word, and determining a location chain including a chain node with the greatest degree of association with the feature word as the target location chain.
According to embodiments of the present disclosure, in a case of determining three location chains including “District A-City Aadm_2′-Province Aadm_2″”, “District A-City Aadm_1′-Aadm_1′” and “City A-Province Aadm_3′” for the location information “A” in the text to be recognized, it is further determined that the text to be recognized further contains, for example, a feature word of “Abrother_1”. Due to a greater degree of association between “Abrother_1” and “Aadm_1′”, it may be determined that “District A-City Aadm_1′-Aadm_1′” is the target location chain.
Through above-described embodiments of the present disclosure, another feature disambiguation method is provided, and the target location chain obtained based on the feature disambiguation has a higher accuracy.
According to embodiments of the present disclosure, determining the target location chain having a greatest degree of relevance to the text to be recognized from the at least one location chain according to the feature word indicating the location attribute in the text to be recognized may include: calculating a similarity between the at least one location chain and a target text, where the target text is a text portion in the text to be recognized, and the text portion includes the location information; and determining a location chain with a greatest similarity to the target text as the target location chain.
According to embodiments of the present disclosure, for example, for a location information of “Abrother_1” in the text to be recognized, “District Abrother_1-City Abrother_adm_1′-Abrother_adm_1′” and “District Abrother_1-City Abrother_adm_2′-Province Abrother_adm_2′” may be initially determined. Then, combined with a text content of a text portion, describing “Abrother_1”, in the text to be recognized, the target location chain may be determined by determining a similarity between the text content of this text portion and “Abrother_adm_1′” and a similarity between the text content of this text portion and “Abrother_adm_2″”. For example, if the text content of this text portion contains a feature word similar to a regional feature or a climatic feature of “Abrother_adm_1′”, it may be determined that the target location chain is “District Abrother_1-City Abrother_1_adm_1′-Abrother_1_adm_1′”.
Through above-described embodiments of the present disclosure, another feature disambiguation method is provided, and the target location chain obtained based on this feature disambiguation has a higher accuracy.
According to embodiments of the present disclosure, calculating the similarity between the at least one location chain and the target text may include: calculating a first word vector of each location chain of the at least one location chain; calculating a second word vector of the target text; and determining a similarity between the at least one location chain and the target text according to a similarity between the first word vector and the second word vector.
According to embodiments of the present disclosure, a word vector may indicate an ontology feature and/or an association feature of a word in multiple dimensions. By converting “Abrother_1_adm_1′” “Abrother_1_adm_2″”, a feature word similar to the regional feature or climatic feature of “Abrother_1_adm_1′” and other words into word vectors, the degree of association between different words may be determined in a more refined dimension, and the similarity between different words may be calculated more accurately.
Through above-described embodiments of the present disclosure, a similarity calculation method is provided, which may effectively provide a basic support for a subsequent feature extraction.
It should be noted that the feature disambiguation methods described above are only exemplary embodiments and the present disclosure is not limited thereto. The present disclosure may further include other disambiguation methods known in the art, as long as a unique location chain having the greatest degree of relevance may be determined from a plurality of location chains.
It should be noted that the feature disambiguation methods described above may be used independently or in combination with each other, as long as a unique target location chain having the greatest degree of relevance may be determined.
As shown in
Through above-described embodiments of the present disclosure, a method of recognizing and normalizing an administrative region based on the named entity recognition technology is implemented, which is applicable to a Chinese text to achieve a normalization in combination with the administrative region knowledge graph and perform a disambiguation on the recognition result, so that the accuracy of the recognition result may be improved as much as possible.
