Specific embodiment
Below in conjunction with attached drawing and the embodiment provided, the present invention is further illustrated, and however, it is not limited to this.
First embodiment of the invention provides a kind of method of judgement post skill requirement variation, as shown in Figure 1, should
Method the following steps are included:
Step 1 obtains information relevant to the skill requirement in post.Preferably, information relevant to post technical ability can be text
The electronic information such as this description, picture, video or Non-electronic information.Without limitation, the information relevant to post technical ability
It is text description, for example, job position request explanation or recruitment information.
In the above step 1, it can advanced optimize as the post skill requirement obtained in certain time period is relevant
Information.For example, relevant recruitment information in available 2010-2015 relevant to " assembly electrician " this post, described
Recruitment information can be obtained by recruitment website, wechat recruitment or other acquisition of information channels.The recruitment information includes
The recruitment information of entire industry, is also possible to the recruitment information in some area, for example, Jiangsu Province enterprise's publication with assembly
The relevant recruitment information in one of electrician post, the recruitment information more than one, but thousands of items or larger number grade.
Step 2 carries out feature extraction and statistics to information relevant to the skill requirement in post acquired in step 1.
The feature can be keyword, and by taking " assembly electrician " relevant recruitment information in this post as an example, the feature can be trick
The keyword in information is engaged, the keyword is related to post technical ability or technical ability.After extraction obtains keyword, to keyword into
Row word frequency statistics, and sort according to frequency.Specific keyword extracting method and word frequency statistics method and non-present invention emphasis pass
Note, has existed a variety of relevant keyword extractions and word frequency statistics method in the prior art.In order to more precisely identify pass
Keyword can also include the steps that artificial screening keyword after keyword extraction in the present invention.
Such as the keyword that can be extracted in a certain group of (such as 10000) recruitment information have keyword A, keyword B,
Keyword C ... keyword N.Here only schematical citing, in other implementations, keyword quantity can be 7
A, 15,25 or other quantity.Wherein, keyword A word frequency is 0.6 time/item, it is meant that on average, every recruitment letter
The frequency for occurring the keyword in breath is 0.6, it is understood that there are 6000 keywords in this 10000 recruitment informations
A, keyword A word frequency are 0.9 time/item, and keyword C word frequency is 0.7 time/item ... ..., and specific data are referring to fig. 2.
In Fig. 2, each keyword indicates a knowledge or technical ability.For example, keyword A can be indicated " to weld ", be closed
Keyword B can be " assembling and setting ", keyword C can be " debugging " etc..
It is noted that can only reflect word frequency in Fig. 2, the appearance age of each keyword not can reflect, and show in Fig. 3
The information for the period that the corresponding keyword of having anticipated occurs.
Step 3 judges the variation of the post skill requirement according to the result of word frequency statistics.As shown in figure 3, because each pass
Keyword occurs and the period of distribution is different, may determine that the variation tendency of the post skill requirement by time dimension.
Here, the period can be 5 years, and 3 years, 1 year, half a year, time intervals of one month or other definition；Each period it
Between can be continuous, be also possible to discontinuous.
It is indicated with further reference to the bubble diagram that Fig. 4, Fig. 4 are Fig. 3 data.Trend can be more intuitively found out by Fig. 4
Variation.
Firstly, the word frequency variation of certain keywords is little and continuous, such as keyword D, keyword E, key in Fig. 4
Word J etc., this shows that technical ability relevant to these keywords is basic demand of the post within period period 1- 10.Here
List 10 periods, only schematical explanation, be also possible to 3 periods, 8 periods, 15 periods or
The period of person's other quantity.Further, if on each period within several periods, a certain keyword word frequency variation
No more than first threshold, such as 30%, then show that the relevant technical ability of the keyword is the basic skills requirement in the post.
Secondly, certain keywords do not occur within the period of beginning, and occur in the period below in Fig. 4,
Such as keyword F and keyword H, and each period of two keywords within several periods is (such as when period 7-
Between section 10) on word frequency be more than second threshold, such as 0.08, then show that the relevant technical ability of keyword is that the post is newest and stresses
Skill requirement.Alternatively, in the word frequency in several nearest periods relative to the word frequency in several each periods before
Incrementss have been more than third threshold value, such as the keyword B in Fig. 4, then show that the relevant technical ability of keyword is the newest side in the post
The skill requirement of weight.Here the calculation of word frequency 0.08 is frequency of occurrence divided by total sample size, and others can also be used
Mode calculates word frequency, it is only necessary to keep the word frequency calculation of each keyword consistent.
Again, in Fig. 4, certain keywords always exist within the period of beginning, and within the period below not
Occur or word frequency reduction is more apparent, such as keyword G and keyword I, generally, if some keyword is in several times
Word frequency persistently reduces on each period (for example, for keyword I, in period period 7- 10) in section, then shows
The relevant technical ability of keyword is the skill requirement that the post is eliminated or is replaced.
According to the above rule, it can be found that worker's skill requirement in a certain post, the knowledge mapping of worker in other words
Variation tendency, that is, the relevant skill requirement (or knowledge) of the keyword gradually lowered from word frequency gradually increases to word frequency
The relevant skill requirement of keyword (either knowledge) transfer or drift.
Because keyword derives from the recruitment information of enterprise, that is, demand of the enterprise to post is reflected, therefore, by above-mentioned
The post technical ability or knowledge variation tendency that method is established, worker can be helped to understand being capable of the basis that has of a certain post
Technical ability and it is newest stress technical ability, if not have corresponding technical ability or technical ability insufficient for it, can pointedly select basic skill
Energy and the newest technical ability stressed go to learn, rather than blindly select, the technical ability for avoiding study that from will being eliminated.
On the other hand, the keyword in each post can be counted and is added up, such as numerical tool operation person, numerically-controlled machine tool
The word frequency of maintenance, the keyword in posies such as numerically-controlled machine tool supervisor adds up, to be digitally controlled the post technical ability of machine industry
Or knowledge variation tendency.Further, technical solution provided by the invention can be applied to bigger industry, such as equipped
Manufacturing, so as to analyze and show foundational skills having required by the practitioner of equipment manufacture industry and emerging
Technical ability.
In another embodiment, keyword extraction can be carried out for the recruitment information in different regions or area
And word frequency analysis, to obtain different regions to the difference and variation tendency of a certain post skill requirement.Such as Jiangsu Province
Keyword statistics and word frequency analysis are carried out respectively with the assembly electrician post of the laser manufacturing in Jiangxi Province, to obtain two
Save the difference of the skill requirement with regard to the post.In another embodiment, the trick of the different types of group of enterprises can be directed to
Information is engaged to carry out keyword extraction and word frequency analysis, to obtain different enterprises to the difference and variation of a certain post skill requirement
Trend.Such as (here only schematically, it is also possible to for the last 100 enterprise of the world and Chinese the last 100 enterprise with other classification
The group of enterprises that standard is classified) a certain post carry out keyword statistics and word frequency analysis respectively, to obtain different enterprises
Difference of the industry group for the skill requirement in same post.So as to further help worker to find employment positioning accurately.
The present invention also provides a kind of devices of judgement post skill requirement variation, as shown in figure 5, the device includes: letter
Acquiring unit 1 is ceased, for obtaining information relevant to the skill requirement in post, feature extraction and statistic unit 2, to acquisition of information
The information relevant to the skill requirement in post that unit 1 obtains carries out feature extraction and statistics, further includes judging unit 3, according to
The result of word frequency statistics judges the variation of the post skill requirement.
The present invention couple information relevant to the skill requirement in post carries out feature extraction and statistics, according to the knot of word frequency statistics
Fruit judges the variation of the post skill requirement, it can be found that worker's skill requirement in a certain post, worker knows in other words
The variation tendency for knowing map, the post technical ability or knowledge variation tendency established by the above method, can help worker
Solution can the foundational skills that have of a certain post and it is newest stress technical ability, also can be derived that different regions or different enterprises
Difference of the group for the skill requirement in same post.So as to further help worker to find employment positioning accurately.
