The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Referring to fig. 1, a flow 100 of some embodiments of a government event transaction recommendation method according to the present disclosure is shown. The government affair event handling recommendation method comprises the following steps:

step 101, obtaining historical government affair event data, wherein the historical government affair event data comprises structured data, unstructured data and semi-structured data.

In some embodiments, the executive body of the government event recommendation method (e.g., the government service management platform) may first obtain historical government event data. In practice, the historical government event data may be government event data for a preset historical period of time. The government event data may be various data related to the government event including time, place, event name, required materials, and the like. The government affair event can be determined by a designated mode and can also be obtained by certain condition screening. For example, an event containing keywords such as identity documents, social security, etc. may be determined as a government event. Specifically, the identity document transaction and the social insurance transaction are both government affair times. In practice, the format of the data is different due to different sources of the data corresponding to different events, and therefore, the historical government affair event data comprises structured data, unstructured data and semi-structured data.

And 102, performing part-of-speech tagging on the unstructured data and the semi-structured data to obtain tagged data.

In some embodiments, the execution subject may perform part-of-speech tagging on the unstructured data and the semi-structured data to obtain tagged data. For example, the annotation can be performed by using an annotation method such as BIO and BIOSE. The data may be first tokenized and then labeled for each word. Using the BIO labeling method as an example, each word is labeled as "B-X", "I-X", or "O". Wherein "B-X" indicates that the fragment in which the word is located belongs to X type and the word is at the beginning of the fragment, "I-X" indicates that the fragment in which the word is located belongs to X type and the word is at the middle of the fragment, "O" indicates not belonging to any type. And marking to obtain marked data. In the process, the labeling can be assisted by customizing the dictionary, so that the labeling result is more consistent with the scene requirement.

Optionally, on the basis of obtaining the labeled data, the relationship may be identified through the following function or an artificial neural network, that is, the labeled data is classified:

wherein the vector

Sum vector

Respectively corresponding vectors of two data in the marked data,

the standard deviation is indicated. The data can be divided by utilizing the high-dimensional linear divisible characteristic of the function, so that the classified data is obtained after the data are marked.

And 103, performing entity identification on the marked data to determine entities in the marked data, wherein the entities are character entities, event entities and event attribute entities.

In some embodiments, the entity recognition model applied to the government event scenario may be trained in advance, thereby improving the recognition rate in that scenario. For example, the solid recognition model may include algorithms such as Bi-LSTM, CRF (Conditional Random Field), etc. Therefore, the execution subject can continuously perform entity identification on the marked data so as to determine various entities in the marked data. In the application scenario of government event handling, entities may include a human entity, an event entity, and an event attribute entity. The event attribute entity includes an event address, an event time, and the like. The event entity may be an event needing to be transacted in a government affairs service scenario, including but not limited to: certificate transacting, insurance transacting, and the like. The human entity may be, for example, zhang three, li four, etc. In addition, according to the requirement, entity identification can be carried out on the basis of the classification data, and then each entity in the classification data is determined.

And step 104, fusing the marked data with the structured data to obtain fused data, wherein the fused data comprises entity and event attribute information.

In some embodiments, the execution subject may fuse the labeled data with the structured data to obtain fused data. It can be understood that the annotated data has been identified as entities, and various entities therein have been identified. Thus, fusion with structured data is possible. The merging method may be to unify names of synonymous events, for example, the refund event and the refund event are substantially the same event, and may be collectively called a refund event.

In some embodiments, in order to solve the technical problem two described in the background section, "there are problems of irregular naming of events due to different data sources in the historical government event data, for example, the same event has multiple names, which is not beneficial to the training of models", as an inventive point of the present disclosure, the similarity between two texts can be determined by the following formula

：

Wherein, S and T represent two texts,

indicating the number of elements in the intersection of two texts, i.e. the number of overlapping words,

and

respectively representing the number of words of the text S and T,

the number of elements in the union of two texts is represented, i.e. the number of non-repeating words contained by the two texts.

For example, S represents a "refund event", T represents a "refund event",

and

is a predetermined coefficient, for example, 0.5, and the similarity between S and T is 0.675.

On this basis, if the similarity of the two texts is greater than or equal to a preset threshold (e.g. 0.6), the two texts can be considered to represent a synonymous event, and name unification can be performed. If the similarity is smaller than the preset threshold, the events can be regarded as different events, and fusion is not needed.

It can be seen that the problem that the same event has multiple names can be solved by performing the synonymous event fusion through the formula. For two texts, the similarity is related to the overlapped contents on one hand, and is generally expressed by the number of overlapped words, and is related to the different contents on the other hand. For the different content, it is possible to,the above formula takes two expression forms, namely

And

. Two representations, two and one for each overlap, represent two boundary values. On the basis, the weight of each representation mode is controlled through a preset coefficient, so that the similarity of the two texts can be calculated more flexibly and accurately.

And 105, constructing a knowledge graph based on the incidence relation among the entities in the fusion data, wherein the nodes in the knowledge graph represent the entities, and the edges in the knowledge graph represent the incidence relation among different entities.

In some embodiments, the execution subject may construct the knowledge graph with entities as nodes and associations between entities as edges, as shown in fig. 4.

And 106, generating an event handling sequence corresponding to each human entity according to the knowledge graph, wherein the event handling sequence is used for representing handling sequences of a plurality of events corresponding to the human entities.

First, a plurality of events corresponding to each human entity are determined according to the knowledge graph, as shown in fig. 4, a transactor 1 corresponds to an event a, an event B, and an event C. The transactor 2 corresponds to event C, event D, and event E.

Secondly, determining address information corresponding to each event in the plurality of events to obtain an address information set.

Thirdly, determining a target path according to the positions represented by the address information in the address information set, wherein the target path is connected with the positions represented by the address information in series.

In the process, a map interface can be called, and the path planning is carried out by taking the address information as input, so that a target path is obtained. Or a path ranking algorithm is utilized to obtain the target path.

Fourthly, determining an event handling sequence corresponding to each human entity according to the sequence of the target path passing through each position.

For example, the event transaction sequence for transactor 1 may be event C-event B-event A.

In addition, the relation between the positions represented by the address information and the dependency relation of the materials required by the events can be comprehensively considered, and path planning is carried out to determine the shortest path meeting the dependency relation as the target path.

And step 107, training to obtain a government affair event handling recommendation model based on the event handling sequence corresponding to each human entity.

For example, for an event sequence, event C-event B-event a, event a may be used as an input, event B and event C may be used as a desired output, and an artificial neural network (CBOW or Skip-Gram may be used) is trained, so as to obtain a government event handling recommendation model. According to actual needs, the event B, that is, the next event, may be output as expected, or the event B-event C, that is, the subsequent event sequence, may be output as expected.

The objective function used in the above training process may be:

wherein the content of the first and second substances,

is shown in an event

In case of occurrence, event

The probability of occurrence;

is an event

Is represented by a vector of (a) or (b),

is an event

N denotes the total number of events, k is any integer between 1 and N.

The loss function used for the above training may be:

the method provided by some embodiments of the present disclosure performs part-of-speech tagging and entity recognition operations on unstructured data and semi-structured data in sequence, and on this basis, fuses with structured data, thereby achieving the effect of expanding training samples. In addition, the names of the synonymous events can be unified through fusion, so that the training of the model is facilitated.

Optionally, the method further includes: acquiring a to-do event set and user current position information input by a user through a terminal; inputting the to-be-handled event set into a government event handling recommendation model to obtain a to-be-handled event sequence; and generating a transaction path based on the current position information of the user and the sequence of the events to be handled. For example, the current position information of the user is used as a starting point and is sequentially connected with the positions corresponding to the events to be handled in each sequence of the events to be handled, so that the transaction path is obtained. Sending the office path to the terminal so that the terminal displays the office path in the electronic map, wherein the office path comprises position marks corresponding to each event to be handled in the event set to be handled, and the marks are connected through directed line segments; in response to receiving the movement information of a user for a target endpoint in the directed line segment, adjusting the transaction path according to an original position mark and a target position mark corresponding to the target endpoint to generate a target transaction path; and sending the target transaction path to the terminal.

And step 108, acquiring a to-do event set and current position information of the user, which are input by the user through the terminal.

In some embodiments, after training is completed, the trained government event handling recommendation model can be deployed. On this basis, the execution subject may receive the to-do event set and the current location information of the user sent by the terminal. The to-do event set may include a plurality of to-do event identifiers.

Step 109, inputting the to-be-handled event set into the government affair event handling recommendation model to obtain the to-be-handled event sequence.

In order to solve the technical problem three described in the background section, in some embodiments of the present disclosure, before determining a target path according to positions represented by respective address information in an address information set, and before the target path concatenates the positions represented by the respective address information, the method further includes: and determining the dependency relationship of a plurality of events corresponding to each human entity. For example, identity cards are needed for handling insurance services, which depend on handling identity card services, and "handling insurance services" needs to be arranged after "handling identity card services". Therefore, the problem that the events cannot be handled smoothly due to the fact that only the position relation is considered is avoided. On the basis, sequencing a plurality of events according to the dependency relationship to obtain an event dependency sequence; and determining a target path according to the positions represented by the address information in the address information set, wherein the target path is connected with the positions represented by the address information in series, and the method comprises the following steps: and determining the shortest path of each event in the series event dependency sequence as a target path. Therefore, the shortest path can be determined on the premise of meeting the dependency relationship so as to save transaction events.

Wherein, the dependent sequence can be one or more. For example, if there is a dependency relationship between each of a plurality of events, a dependency sequence is generally obtained, for example, if event C depends on event B, and event B depends on event a, then the dependency sequence is: event C-event B-event a. If, for example, event C depends on event B, and both event C and event B have no dependency relationship with event a, then multiple dependency sequences, event C-event B-event a, event a-event C-event B, may be obtained. In the case where there are a plurality of dependency sequences, the shortest path may be set as the target path. Therefore, the dependency relationship among the events is considered, so that the problem that the transaction sequence is wrong and materials are lacked is avoided, and the event transaction efficiency is improved.
