Detailed Description
For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Currently, the complex and various post information makes it difficult for many job seekers to find post information suitable for themselves. The employment crowd relates to students at the university, employment-losing employment-waiting staff, young employment-losing staff, elderly employment crowd, retired soldiers and the like. The employment number is large, the employment situation is severe, under the influence of social factors, staff changes greatly, the traditional recruitment information recruitment mode is subjective, the accuracy of accurately matching the posts is poor, and the current descriptions of all enterprises for the same posts are different and are not clear to position. Thus, it is difficult for the employment group to quickly find a proper position of the employment group. Recruitment is also difficult to quickly screen out suitable post response personnel among a large number of people waiting for employment.
Based on the above, the embodiment of the application provides employment information processing method and equipment for a crowd to be employment, which are used for solving the problems that employment information is processed, identified and screened mainly by manpower, the work is complex, the workload is large, and the labor cost is wasted, and the current personnel to be employment cannot quickly find out proper work according to the working experience and technical capability mastered by the personnel to be employment, so that the problem that the normal employment and long-term occupation planning of the personnel to be employment are influenced due to blind delivery of resume delivery is solved.
Various embodiments of the present application are described in detail below with reference to the accompanying drawings.
The embodiment of the application provides a employment information processing method for a crowd to be employment, as shown in fig. 1, the method may include steps S101-S105:
s101, the server acquires a plurality of post information.
The post information at least comprises: post name, post responsibility text, post demand text.
In embodiments of the present application, the post information may include post names, post responsibility texts, post requirement texts, e.g., attendant, post responsibility texts: welcome/pass/serve/sanitation; post demand text: physical health/appearance with good quality of qi/18-30 years old/star hotel/kender, mcdonald, must win guests/health card/shift.
It should be noted that, the server is merely an exemplary implementation subject of the employment information processing method for the crowd to be employment, and the implementation subject is not limited to the server, and the application is not limited thereto specifically.
In this embodiment of the present application, before the server obtains the plurality of post information, the method further includes:
the server acquires a plurality of recruitment information and post keywords corresponding to the recruitment information.
The server may acquire recruitment related text by using a crawler program or an octopus and a back collector, and perform data management on the related text, for example: removing special character data such as br, div, span and the like; duplicate data (one post ambiguous) is removed, missing data and supplemental incomplete data; and (3) treating places where the work description field is inconsistent with other fields of the post, removing misleading post description, and eliminating ambiguous data. Translating English data into Chinese data.
Then, the server sequentially combines the post keywords into post keywords according to the position sequence of the post keywords in the recruitment information, takes the post keywords as training samples, and inputs the two-way LSTM-CRF model to train the two-way LSTM-CRF model.
Specifically, the post description related text is segmented according to punctuation marks, the post requirements of the special character pattern= |post description are filtered regularly, then long sentences are segmented into short sentences, then entity dictionaries and word boundaries are obtained, and words at each position in the short sentences are converted into word vectors. Combining a plurality of word vectors to obtain a short sentence as the input of a model, and providing the short sentence to the model for learning
The step of obtaining the post information by the server specifically comprises the following steps:
firstly, the server screens position keywords in a plurality of recruitment information through a bidirectional LSTM-CRF model, so that the screened position keywords are used as position responsibility sample words.
For example, the recruitment information includes "handling law office cases, legal consultation, prosecution, evidence arrangement, and complaint, and participating in internal training of regular organization of law and courses of related activities, forums, training, etc. held together by external industry associations and institutions", and then the post responsibility sample word can be obtained through a bidirectional LSTM-CRF model: legal consultation drafting complaint participation training … … for treatment law case
Then, the server determines the post requirement sample words corresponding to the post responsibility texts in the recruitment information.
The post requirement sample word generation uses an automatic summary generation technology. The automated generation of the post requirements is described by giving a post requirement sample vocabulary B with |B| different posts, i.e
Wherein X is i Is a job, which describes the responsibility of the ith job, Y i Is a post requirement that describes the various capacity requirements of this post. Specifically, for each job role X i Assuming that it contains H d Individual words, i.e.
The post requirements typically contain multiple sentences to describe different capacity requirements, so each post requirement Y i Represented as
Y i ＝{y 1 ，y 2 ，...y N }。
Wherein y is i Is the j-th sentence. For example, give 5 post requirement sentences, i.eN=5, which corresponds to introduction of professional institutions, academia, work experiences, communication capabilities, thinking about the ability. Further assume that each y i Included
Individual words, i.e.
For example, the post responsibility sample word in the above example may correspond to the following post requirement sample word: law, law qualification certificate.
Then, the server inputs the post responsibility sample words and the post requirement sample words into a keyword extraction model for training so as to obtain post information through the trained keyword extraction model. The keyword extraction model is a TextRank algorithm model.
The server can sort the post responsibility sample words and post requirement sample words by a voting mechanism, sentences after sorting are post information samples, and further training of the keyword extraction model is completed, so that post information is extracted through the keyword extraction model after training is completed.
By the short text description identification mode, post information is generated, and the situation that the enterprise can not normally match with the employment staff capacity and posts due to the description difference of different posts can be avoided. And the text is processed, so that the calculation amount of a server can be saved, and the employment information processing time is shortened.
S102, the server determines a first evaluation score corresponding to each position information based on recruiter information corresponding to each position information and resume information of the currently pending person.
The first evaluation score represents the matching degree of the currently undetermined person and the post information.
In this embodiment of the present application, the server determines, based on recruiter information corresponding to each position information and resume information of the currently pending person, a first evaluation score corresponding to each position information, including:
firstly, the server determines cosine similarity between a text corresponding to the resume information and a text corresponding to each recruiter information according to resume information of a current undetermined person and information of each recruiter.
The corresponding text is an evaluation text for the post.
The resume information of the pending person can be resume related information uploaded by the pending person, and the server determines cosine similarity of the recruiter information and the resume information. The server can determine the similarity between the resume of the undetermined person and the information of each recruiter through a collaborative filtering recommendation algorithm.
Specifically, the server encodes the evaluation text of the posts in the resume information and the evaluation text of the posts by each recruiter in the recruiter information, for example: work overtime is more, and the codes are two vector work overtime [1, 0] and more [2,0,0]; the working competition pressure is large, encoded as working competition [1,2,0], the pressure is large [1,2,1] … …, and then the cosine similarity of the corresponding text is calculated by the following cosine similarity calculation company:
wherein cosA is cosine similarity of evaluation text J corresponding to resume information and evaluation text Z corresponding to recruiter information, J x To evaluate the xth word vector of text J, Z x To evaluate the xth word vector of text Z, y is the total number of word vectors.
And then, the server generates a similarity matrix of the currently pending person and each recruiter according to each cosine similarity.
The server may build a similarity matrix to simplify the amount of computation when computing the evaluation scores. Specifically, after the server obtains the cosine similarity between the evaluation text obtained according to the resume information of the current pending person and the evaluation text of the recruiter for the same post, the current pending person and the recruiter can be used as rows of the matrix, and the post can be used as columns of the matrix, so that the cosine similarity matrix of the evaluation text of the current pending person and the recruiter for each post can be obtained. The recruiter in the similarity matrix may be a recruiter with cosine similarity smaller than a preset value, after the recruiter in the similarity matrix is removed, for example, the recruiter information with cosine similarity smaller than a is removed when the preset value is a, and the recruiter close to the current undetermined person and having similar preference is reserved. The method and the system can write cosine similarity between all recruiters and the current undetermined person in the similarity matrix, and reject recruiter information with cosine similarity smaller than a before the first evaluation score is generated subsequently.
Then, the server determines a position score corresponding to the current pending person as a first evaluation score based on the evaluation text of each recruiter for each position and the corresponding cosine similarity in the similarity matrix.
The server can determine the evaluation score corresponding to the evaluation text according to the evaluation text of each recruiter for each post, and the server can determine the evaluation score corresponding to the evaluation text by using a preset model or a preset text comparison table (text and evaluation score comparison table). The server determines a similarity matrix generated by each historical recruiter and the pending person, and then calculates the similarity with the historical recruiter when the current pending person evaluates each post by the following formula.
Wherein A is 1 A is the similarity of the evaluation of the third post by the pending person to the first historic recruiter, a 1 For the evaluation score of the first post by the pending person, a 2 For the evaluation score of the undetermined person on the second post, b 1 A first post evaluation score for a first historic recruiter, b 2 A rating score for the second post for the first historic recruiter.
A first evaluation score is calculated according to the following formula, taking three historical recruiters as an example:
wherein T is 3 For the first evaluation score of the pending person for the third station,
for similarity of the evaluation of the third position by the pending person and the second historic recruiter,/for the evaluation of the third position by the pending person and the second historic recruiter >
B for similarity of the pending person to the third post's evaluation of the third historic recruiter 3 A third post evaluation score for the first historic recruiter, c 3 A third post evaluation score for the second historical recruiter, d 3 And a third post evaluation score for the third historical recruiter.
After the first evaluation scores of the undetermined personnel on each post are obtained according to collaborative filtering recommendation, a certain difference exists between the recommended post and an expected result, so that the server further processes employment information through the following method.
S103, the server determines a corresponding second evaluation score of the undetermined person corresponding to the first evaluation score according to the first evaluation score and a preset lingering semantic model.
In this embodiment of the present application, the server determines, according to the first evaluation score and a preset lingering semantic model, a corresponding second evaluation score of the undetermined person corresponding to the first evaluation score, including:
firstly, the server inputs resume information of the currently pending person and an evaluation text corresponding to the first evaluation score into the lingo-meaning model so that the lingo-meaning model determines a scoring matrix corresponding to the currently pending person and the recruiter corresponding to the first evaluation score.
The server can input the resume information and the evaluation text corresponding to the scores of the first evaluation scores on all posts, namely the evaluation text corresponding to the resume information, of the undetermined personnel on all posts, wherein the evaluation text can be generated through the resume information and the obtained first evaluation scores. The generation means that when the resume information of the undetermined person does not have the evaluation text of the pair X position, the first evaluation score is 5 on the pair X position, the corresponding historical recruiter m is 5 on the pair X position, and the evaluation text of m can be used as the evaluation text of the undetermined person. And further, processing the evaluation text through the latent semantic model, and obtaining the score of the undetermined personnel on each post through the pre-trained latent semantic model.
The latent model can determine the interest degree of the personnel to be determined in the post hidden class and the hidden class weight of the post, and the objective function of the latent model is continuously optimized through the loss function constructed by the punishment factors of the latent model, so that the high-quality evaluation score output by the latent model is obtained.
And then, the server carries out factorization processing on the scoring matrix through the latent semantic model and a preset loss function until the preset loss function meets preset conditions so as to decompose the scoring matrix into a user scoring matrix and a post weight matrix.
After the scoring matrix is obtained, the scoring matrix can be decomposed into a user scoring matrix and a post weight matrix according to the interestingness of the personnel to be determined to the post hidden class and the post hidden class weight. In order to ensure the minimum error during decomposition, the decomposition is performed by setting a loss function, for example, the random gradient descent method is used for minimizing, solving the loss function, decomposing the scoring matrix, and determining that the decomposition is completed under the condition that the loss function is smaller than a set value.
Then, the server determines predictive rating scores for the posts of the currently pending person based on the user rating matrix and the post weight matrix.
The server can calculate the product by using the user scoring matrix and the post weight matrix, and calculate the predictive evaluation score by the following formula:
wherein r is ui Predictive evaluation score for recruitment position i for person u, p uk Scoring the interest level user of the kth hidden class of the post for the person u, which corresponds to a user scoring matrix; q ki The effect of the kth hidden class on position i is scored for a weight that corresponds to the position weight matrix.
Then, the server takes the weighted average of the first evaluation score and the predicted evaluation score as the second evaluation score.
After the server obtains the predictive evaluation score outputted by the latent semantic model, a weighted average of the first evaluation score and the predictive evaluation score corresponding to the first evaluation score is obtained, and the weighted average is used as a second evaluation score. The weights corresponding to the first evaluation score and the predicted evaluation score in the weighted average may be set by the user, which is not specifically limited in this application. The implicit behavior of the user is introduced into the scoring consideration of all posts, so that more accurate recommendation results can be obtained when posts are recommended.
S104, the server determines a matching probability value corresponding to the resume information and each post information through a pre-trained deep forest model.
In this embodiment of the present application, before determining, by the server, the matching probability value corresponding to the resume information and each post information through the pre-trained deep forest model, the method further includes:
the server acquires a plurality of resume samples and a plurality of post information samples.
