[0052] In order to make the objectives, technical solutions and advantages of the present invention clearer and more comprehensible, the present invention is further elaborated in combination with specific embodiments and with reference to accompanying drawings.
[0053] In relevant embodiments of the present invention, some attributes of a user can be portrayed in a platform typically according to direct consuming behaviors of the user (such as group buying, take-away, reservation, movies and tickets). For example, according to behaviors of a customer in a platform, such as the movies or tickets that the customer has browsed or transacted, the age and likings of the user can be analyzed and portrayed.
However, excavating financial attributes of a user simply from transactions, browsing and other behaviors of the user is likely to be limited by platform category, resulting in inadequate excavation of financial attributes of the user.
However, excavating financial attributes of a user simply from transactions, browsing and other behaviors of the user is likely to be limited by platform category, resulting in inadequate excavation of financial attributes of the user.
[0054] Based on the foregoing problems, some embodiments of the present disclosure provide a label information obtaining method and apparatus, an electronic device and a computer readable medium, structuralize performance addresses by natural language processing technology based on performance addresses of a user, and further obtain housing values, occupation, living habits and so on of the user from structuralized information, thereby extracting relatively strong financial attributes.
[0055] FIG. 1 is a flow chart of a label information obtaining method provided in an embodiment of the present disclosure, comprising the following steps:
[0056] As shown in FIG. 1, at step S110, classifying performance addresses of a user to obtain classification results of the performance addresses, wherein the performance addresses are addresses where the user performs orders.
[0057] As shown in FIG. 1, at step S120, analyzing according to performance behaviors of the user specific to the performance addresses in combination with the classification results to obtain label information of the user.
[0058] FIG. 2 is a flow chart of an alternative label information obtaining method provided in an embodiment of the present disclosure, comprising the following steps:
[0059] As shown in FIG. 2, at step S210, classifying performance addresses of a user to obtain classification results of the performance addresses, wherein the performance addresses are addresses where the user performs orders.
[0060] As shown in FIG. 2, at step S220, conducting attribute analysis of the classification results in combination with an industry information database to obtain attribute information of the performance addresses.
[0061] As shown in FIG. 2, at step S230, analyzing according to performance behaviors of the user specific to the performance addresses in combination with the classification results and the attribute information to obtain label information of the user.
[0062] Different from the method flow shown in FIG. 1, the flow shown in FIG. 2 further conducts attribute analysis according to classification results in combination with an industry information database so that user's label can be deeply analyzed according to performance behaviors of the user in combination with classification results and attribute information of the user to obtain label information of the user.
[0063] The label information obtaining method in this exemplary embodiment obtains label information of a user, such as occupation, housing values, living habits and other relatively strong financial attributes through classification and attribute recognition of performance addresses of the user and through analysis in combination with performance behaviors of the user, and evaluates consumption power of the user under the precondition of not obtaining sensitive information of the user.
[0064] Below the flow shown in FIG. 2 is taken as an example to further describe every step of the label information obtaining method in embodiments of the present disclosure.
[0065] At step S210, classifying performance addresses of a user to obtain classification results of the performance addresses.
[0066] In an embodiment of the present disclosure, the performance addresses are addresses provided by the user to perform orders. For example, addresses written by a user for order performance when the user places orders under 020, such as addresses relating to take-away or online taxi hailing and other orders, are performance addresses. One take-away order contains a performance address, and one online taxi hailing order contains two performance addresses (departure place and destination). The performance addresses in this embodiment mainly take the performance address in the take-away order as an example, while the two performance addresses in the online taxi hailing order, including departure place and destination, are also applicable.
[0067] In an embodiment of the present disclosure, at step S210, classifying the performance addresses to obtain classification results of the performance addresses can be achieved by the following two methods for offline model training, to be specific:
[0068] Methods for offline model training may include:
[0069] 1) conducting classified labeling of the historical performance addresses based on word vectors to obtain mapping relations between performance addresses and categories;
[0070] obtaining the classification results specific to the performance addresses in combination with the mapping relations between performance addresses and categories; or
[0071] 2) conducting Softmax training of the historical performance addresses based on word features to obtain a text classification model;
[0072] inputting the performance addresses to the text classification model and outputting the classification results.
[0073] The foregoing historical performance addresses are addresses where a plurality of users in a platform perform historical orders.
[0074] FIG. 3 is a flow chart of classified labeling based on word vectors in an embodiment of the present disclosure, comprising the following steps:
[0075] As shown in FIG. 3, at step S301, extracting trunk information from the historical performance addresses.
[0076] In an embodiment of the present disclosure, before this step, the method further comprises filtering all historical performance addresses obtained from the platform. Filtering methods include deduplication and other operations.
[0077] For example, a complete performance address can be as follows:
[0078] Zhaofeng Plaza, Changning Road, Shanghai City (Fangtang Town opposite to Xiao Nan Guo on Floor 4)
[0079] The trunk information in the foregoing performance address is "Zhaofeng Plaza, Changning Road, Shanghai City". At this step, information in the brackets is not considered for the time being.
[0080] As shown in FIG. 3, at step S302, conducting word segmentation of the trunk information by word segmentation technique to obtain a plurality of address segments.
[0081] In an embodiment of the present disclosure, for English addresses, space is used as a separator during word segmentation, and there are many word segmentation techniques for Chinese addresses and in general, word segmentation based on dictionary matching and Markov model can be selected according to the requirements.
[0082] Still taking the foregoing performance address as an example, address segments obtained from step S202 are:
[0083] Zhaofeng Plaza, Changning Road, Shanghai City
[0084] As shown in FIG. 3, at step S303, converting the plurality of address segments into word vectors.
[0085] In an embodiment of the present disclosure, at this step, word2vec technique (e.g., skipNgram model) is adopted to convert address segments into word vectors, and the word vector technique trains a neutral network model through context between words.
[0086] Still taking the foregoing performance address as an example, each of address segments "Shanghai City", "Changning Road" and "Zhaofeng Plaza" will obtain a word vector.
In the end, these word vectors are accumulated to obtain word vectors to which this address text corresponds.
In the end, these word vectors are accumulated to obtain word vectors to which this address text corresponds.
[0087] As shown in FIG. 3, at step S304, clustering the word vectors.
[0088] In an embodiment of the present disclosure, clustering can be conducted through kmeans. For example, performance addresses are clustered into 1000 clusters.
The number of clusters obtained from clustering is set according to the need. The more the clusters are, the larger the workload of needed subsequent labeling will be.
The number of clusters obtained from clustering is set according to the need. The more the clusters are, the larger the workload of needed subsequent labeling will be.
[0089] As shown in FIG. 3, at step S305, conducting corresponding classified labeling of classification results of trunk information of the performance addresses according to clustering results.
[0090] In an embodiment of the present disclosure, performance addresses in each cluster are labeled according to clustering results. For example, 1000 clusters of performance addresses closest to the clustering center are artificially labeled, thereby labeling trunks of all performance addresses. For example, classified labeling of Zhaofeng Plaza is shopping mall, classified labeling of Longemont Hotel is hotel, and classified labeling of Regents Park is housing.
[0091] FIG. 4 is a flow chart of text classification training based on word features, comprising the following steps:
[0092] As shown in FIG. 4, at step S401, configuring a corresponding rule for address text and classification.
[0093] In an embodiment of the present disclosure, an artificial dictionary can be configured.
The artificial dictionary contains a corresponding rule for address text and classification, and a format can be: text ¨>classification.
The artificial dictionary contains a corresponding rule for address text and classification, and a format can be: text ¨>classification.
[0094] As shown in FIG. 4, at step S402, matching the historical performance addresses by multi-pattern matching, and outputting corresponding classification results according to the corresponding rule if the historical performance addresses are matched with the address text.
[0095] In an embodiment of the present disclosure, multi-pattern matching is to judge whether the antecedent of the rule has an inclusion relation in the address text. Such inclusion relation is multi-pattern matching, using the foregoing corresponding rule and multi-pattern matching can handle some failure cases or bad cases, the antecedent of the rule is address text, and the consequent of the rule is hotel, i.e., category.
[0096] For example, a rule in an artificial dictionary is guesthouse ¨>hotel. Based on this corresponding rule, if text **guesthouse is given, because "guesthouse" is contained, it is concluded that the category of "**guesthouse" is hotel.
[0097] As shown in FIG. 4, at step S403, segmenting the performance addresses, performing multiple combination of obtained segments and conducting Softmax training based on features of a single segment or a plurality of segments to obtain the text classification model.
[0098] In an embodiment of the present disclosure, for corpus obtained from artificial labeling, performance addresses are subjected to word segmentation and combination of bigram (2 segments) and trigram (3 segments). Based on features of unigram (one segment), bigram and trigram, Softmax training is used to obtain a text classification model.
[0099] After training based on the offline model shown in FIG. 3 and FIG.
4, obtained performance addresses are classified. This process is a process of online prediction. FIG. 5 is a flow chart of classifying performance addresses of a user, comprising the following steps:
4, obtained performance addresses are classified. This process is a process of online prediction. FIG. 5 is a flow chart of classifying performance addresses of a user, comprising the following steps:
[0100] As shown in FIG. 5, at step S501, extracting trunk information from performance addresses. Classified labeling can be obtained from address labeling based on word vectors, through a flow shown in FIG. 3.
[0101] As shown in FIG. 5, at step S502, predicting using a word feature model, and predicting trunk information of performance addresses and content except trunk information (e.g., content in brackets) in turn to obtain prediction results. For example, prediction is conducted using a flow shown in the foregoing FIG. 4. If a µrule in the artificial dictionary can be hit, then classification results are returned directly according to a corresponding rule, otherwise the Softmax model is used to train obtained classification results.
[0102] In a process of online prediction, a prediction method based on word vectors and clustering does not consider content except trunk information (e.g., content in brackets) because the content in the brackets has many distracters, affecting clustering results. However, during online prediction, the offline training model will act upon trunk information and non-trunk information in turn, and then prediction results to which the content in the brackets corresponds are adopted because the address in the brackets is more accurate and concrete.
[0103] For example, when only trunk information is considered, the classification result is:
[0104] Zhaofeng Plaza, Changning Road, Shanghai City shopping mall
[0105] If the non-trunk information in the brackets is considered, the classification result is:
[0106] Zhaofeng Plaza, Changning Road, Shanghai City (Fangtang Town opposite to Xiao Nan Guo on Floor 4) incorporated business
[0107] As Fangtang Town is a mass-innovation space, its corresponding category should be incorporated business rather than a shopping mall. Apparently, the latter classification result is more accurate.
[0108] Before prediction at step S502, localizers of performance addresses are processed.
For example, if a performance address contains "opposite to...", localizer "opposite to" will be omitted.
For example, if a performance address contains "opposite to...", localizer "opposite to" will be omitted.
[0109] At step S220, conducting attribute analysis of the classification results in combination with an industry information database to obtain attribute information of the performance addresses.
[0110] In an embodiment of the present disclosure, before conducting attribute analysis of the classification results in combination with an industry information database, this step further comprises:
[0111] a step of establishing an industry information database, specifically comprising the following steps:
[0112] firstly, pre-processing industry classification information;
secondly, establishing an industry information database according to preprocessed industry classification information.
secondly, establishing an industry information database according to preprocessed industry classification information.
[0113] The pre-processing can obtain, clean and structuralize address, industry and other information by means of external trading and/or crawling of public data to obtain information in a triple form.
[0114] The established industry information database contains a plurality of pieces of information, and each piece of triple information comprises:
[0115] a label; classification results; attribute information;
[0116] The classification results include: at least one or more of housing, hospital, hotel, office building and leisure and entertainment venue; the attribute information includes: at least one or more of housing price, hospital type, hotel star rating, office building grade and leisure and entertainment venue grade.
[0117] For example, information in an industry information database is as follows:
[0118] Property = Regents Park; housing; housing price = Y 100,000/m2;
[0119] Hotel = Shangri-La; hotel; hotel star rating = 5 stars;
[0120] Hospital = Zhongshan Hospital; hospital; hospital category = Grade-A
tertiary hospital
tertiary hospital
[0121] In an embodiment of the present disclosure, at this step, conducting attribute analysis of the classification results in combination with an industry information database to obtain attribute information specifically comprises:
[0122] obtaining corresponding attribute information, of the performance addresses through forward maximum matching of information in the classification results and the industry information database.
[0123] Here, an algorithm of forward maximum matching is to separate a character string, with a limitation to separation length, then match separated character sub-strings with the words in a dictionary, and if the matching is successful, then a next round of matching is conducted until all character strings are processed; if the matching is not successful, then a word is removed from the tail of the character sub-string and matching is conducted again , and the above operation is repeated.
[0124] For example, a performance address is:
[0125] Regents Park (306, BLK 12)
[0126] Firstly, an obtained classification result is housing, then screening is conducted according to the second row in the industry information database, which is housing, to obtain housing-related entities, and then an entity containing Regents Park is obtained through forward maximum matching, and an attribute to which the performance address corresponds, i.e., an entity of housing price information, is obtained. That is, the housing price is Y 100,000/m2.
[0127] At step S230, analyzing according to performance behaviors of the user specific to the performance addresses in combination with the classification results and the attribute information to obtain label information of the user.
[0128] In an embodiment of the present disclosure, before specific analysis, this step further comprises:
[0129] obtaining performance behaviors of the user specific to the performance addresses;
wherein the performance behaviors include: at least one of the following information, including workday performance times, non-workday performance times, time span of performance, and labeling of performance addresses by the user.
wherein the performance behaviors include: at least one of the following information, including workday performance times, non-workday performance times, time span of performance, and labeling of performance addresses by the user.
[0130] In an embodiment of the present disclosure, analyzing according to performance behaviors of the user specific to the performance addresses in combination with the classification results and/or the attribute information to obtain label information of the user comprises:
[0131] if workday performance times of the user are greater than or equal to a first threshold value, and the classification result is hospital, then obtained label information of the user is occupation, which is medical staff; or if non-workday performance times of the user are greater than or equal to a second threshold value, and the classification result is housing, and a housing price in the attribute information is greater than or equal to a third threshold value, then obtained label information of the user is a high-end living quarter.
[0132] The threshold values referred to in the foregoing mapping process can be set according to the need. For example, the first threshold value to which the workday performance times correspond can be set to be five times, and the third threshold value to which the housing price corresponds needs to be set in consideration of various cities.
[0133] Analysis and mapping is conducted according to text extracted from given performance addresses by the user and performance behaviors of the user specific to the performance addresses (workday performance times, holiday performance times, time span of performance, labeling of performance addresses by the user, and other information) to obtain label information of the user.
[0134] Example: If performance address category = office building, and the performance address is labeled as a place of work by the user, then it is speculated that the user is a white-collar worker, i.e., the label information is white-collar worker.
[0135] If address category = housing, and developer = Vanke, and housing price =
Y 75,635.0/m2, the time span of performance at this address is >1 year, and the holiday performance times at this address are >=5, then it is speculated that the user lives in a high-end living quarter, i.e., the label is high-end living quarter.
Y 75,635.0/m2, the time span of performance at this address is >1 year, and the holiday performance times at this address are >=5, then it is speculated that the user lives in a high-end living quarter, i.e., the label is high-end living quarter.
[0136] A group fact label obtained from structuralized information of performance addresses has certain sequencing ability in quota and risk of the user and can be used as a strong financial attribute of the user.
[0137] Based on the foregoing flow, without directly obtaining information of the user and classifying performance addresses of the user, the present disclosure can judge if the user performs in a place of residence (the performance address category is housing) or in a place of work (the address category is office building or incorporated business) or in any other place.
Then on the basis of classification, attribute information of performance addresses of the user can be further analyzed by associating the established industry information database with performance addresses, and label information of the user, such as housing values, occupation, living habits and other information, is obtained in combination with performance behaviors of the user (performance frequency, workday performance frequency, holiday performance frequency, time span of performance dates, etc.), thereby extracting strong financial attributes of the user.
