In one embodiment, verifying the trustworthiness of the first subway rail profile grinding experience includes:
acquiring the credibility of polishing experience of the profile of the first subway steel rail;
when the credibility is larger than or equal to a preset credibility threshold, passing verification; otherwise, not pass; the reliability threshold may be, for example: 85;
the method for obtaining the credibility of the polishing experience of the first subway steel rail profile comprises the following steps:
acquiring a source scene of first subway steel rail profile polishing experience; the source scene is a scene that technicians with rich grinding experience of the subway rail profile can share the grinding experience of the subway rail profile, for example: technical communication forum, weChat/QQ/nail group, etc.;
Matching the source scene with a trusted source scene in a preset trusted source scene; the trusted source scene is a trusted source scene, for example: a micro-letter group and the like which are used for sharing the polishing experience of the subway rail profile by technicians with rich polishing experience of the subway rail profile in a subway company to which the system is applied;
when the matching is consistent, the credibility is calculated according to a preset target value; otherwise, extracting a dialogue record between a publisher of the first subway rail profile polishing experience from the source scene and a browser of the first subway rail profile polishing experience in the source scene; when the matching is met, the source scene is credible, the credibility is directly calculated according to a target value, and the target value is larger than a credibility threshold; the publisher is a technician with rich polishing experience of the subway rail profile, after the publisher publishes the polishing experience of the first subway rail profile in the source scene, a browsing party browses, and evaluation, questioning and the like can be performed during browsing, so that dialogue records are generated with the publisher;
counting the total number of records of the dialogue records;
counting a first record number of dialogue records conforming to a first dialogue record condition;
Counting a second record number of dialogue records conforming to a second dialogue record condition;
based on the total number of records, the first number of records and the second number of records, calculating the credibility according to the following calculation formula:
σ＝ρ 1 ·n 1 +ρ 2 ·K+ρ 3 ·(N-n 1 -n 2 )
wherein sigma is credibility, n 1 For the first number of recordings, K is an intermediate coefficient, N is the total number of recordings, N 2 For the second record number ρ 1 、ρ 2 And ρ 3 D is a preset constant for a preset weight value; the weight value can be set in advance by technicians according to requirements; the constant may be, for example: 30;
the more the first record number of dialogue records conforming to the first dialogue record condition is, the higher the credibility degree of the polishing experience of the profile of the first subway steel rail is represented; the more the second record number of dialogue records conforming to the second dialogue record condition, the lower the degree of confidence representing the grinding experience of the first subway rail profile; therefore, in the formula, the credibility is in a direct proportion relation with the first record number and in an inverse proportion relation with the second record number; the total number is subtracted by the first record number and the second record number in turn to obtain the number of dialogue records which do not accord with the first dialogue record condition or the second dialogue record condition, and the larger the value is, the more times the first subway rail profile grinding experience is discussed are represented, the degree of credibility of the first subway rail profile grinding experience is represented to a certain extent, and the proportional relation is also formed between the total number and the credibility; in addition, when the second record number is 0, a constant preset by an intermediate coefficient is given, the calculation of the credibility is included, and generally, the second record number is 0, the artificial 0 for questioning and negating the polishing of the profile of the first subway steel rail is explained, and the polishing experience of the profile of the first subway steel rail is indirectly explained to be more credible;
Wherein the first dialogue recording condition includes:
the cooling time length of the dialogue record falls in a preset first cooling time length interval; the cooling time period includes: the target side reads the last speaking but not replying duration in the dialogue record; the target party is the publisher or the browser of the last speaker in the non-dialogue record; the first cooling duration interval may be, for example: 2 hours to 7 days;
the first semantics of the last preset number of utterances of the browsed party in the dialogue record are matched with at least one first trigger semantics in a preset first trigger semantics library; the preset number may be, for example: 3, a step of; the first trigger semantics are semantics that reflect that the viewer experiences a positive perspective (e.g., support, endorsement, approval, etc.) on the first subway rail profile grinding, such as: "do so very well" etc.;
in general, there are cases where the confidence level of the polishing experience of the profile of the first subway rail is high: after the browsing party and the issuing party communicate, the two end the conversation, any party does not reply continuously within a certain time, and the browsing party holds a positive view on the polishing experience of the first subway rail profile before the conversation ends. The two conditions can screen dialogue records conforming to the situation, so that the more the first record number of dialogue records conforming to the first dialogue record condition is, the higher the credibility degree of the polishing experience of the profile of the first subway rail is;
Wherein the second dialogue recording condition includes:
the cooling time period falls within a preset second cooling time period; the second cooling duration region may be, for example: 3 to 10 days;
the dialogue initiator and the dialogue ending person of the dialogue record are all browsing parties;
the first semantics are matched with at least one second trigger semantics in a preset second trigger semantics library. The second trigger semantics are semantics that reflect that the browsing party holds a negative perspective (such as question, negative, etc.) on the polishing experience of the first subway rail profile, such as: "such sanding is clearly not right", etc.
In general, there is one such situation that represents a low degree of confidence in the grinding experience of the first subway rail profile: after the browsing party browses the polishing experience of the first subway steel rail profile, the browsing party immediately feels questioned or negated, questions are given to the publisher, after a certain time of communication, the dialogue is ended, the browsing party still presents questioned or negated before the dialogue is ended, and the publisher does not reply right after browsing, so that longer cooling time is generated. The three conditions can screen out dialogue records meeting the condition, so that the more the second records of dialogue records meeting the second dialogue record condition, the lower the credibility degree of the polishing experience of the profile of the first subway rail is represented.
The working principle and the beneficial effects of the technical scheme are as follows:
generally, the polishing experience of the subway steel rail is uploaded by technicians with rich polishing experience of the subway steel rail profile in a subway company to which the system is applied, and the problem of limitation exists in the process: the number of such technicians in a single subway company is limited, and the subway rail polishing experience uploaded by the technicians cannot rapidly cover all the situations of the subway rail needing polishing, namely different areas to be polished, so that the applicability of the subway rail profile polishing experience library for making polishing schemes is not high. The embodiment of the invention can solve the problem: the source scene is introduced, and is a scene which is shared by technicians with rich subway rail profile polishing experience in any subway company and the like, the first subway rail profile polishing experience is obtained from the source scene and is used for a subway rail profile polishing experience library, so that the comprehensiveness of construction of the subway rail profile polishing experience library is improved, and the situation that all subway rails need to be polished, namely different regions to be polished, can be rapidly covered.
In addition, when technicians share the polishing experience of the first subway rail profile in the technical communication forum, weChat/QQ/nail group and the like, the reliability degree of the shared polishing experience of the first subway rail profile needs to be determined, and conventionally, the reliability degree is determined by praying quantity, good scoring quantity, poor scoring quantity, good scoring content, poor scoring content and the like, but in this way, there is a limiting problem: praise, bad authenticity is low, such as: the colleagues of the technicians support sharing of the technicians in a relationship friendly way, and praise is made without reading the content; secondly, some scenes such as WeChat/QQ/nail groups have no praise, good, bad option, resulting in lower applicability; finally, when determining based on the good and bad contents, the semantics of each good and bad contents need to be analyzed one by one to determine the view of the browsing party, which is complicated. The embodiment of the invention can solve the problem: the credibility of the first subway rail profile polishing experience is determined only based on the dialogue record between the publisher of the first subway rail profile polishing experience and the browser browsing the first subway rail profile polishing experience in the source scene, any type of source scene can generate dialogue record, the generated dialogue record indicates that the browser interacts with the publisher to publish comments, the authenticity is higher, in addition, the first dialogue record condition and the second dialogue record condition are introduced, the positive and negative of the view held by the browser are rapidly determined, semantic analysis of each dialogue content is not needed, convenience is improved, and the method has applicability.
In one embodiment, the determination steps for the subway rail to be polished are as follows:
acquiring a preset subway rail line map; wherein, the distribution positions of a plurality of subway rails of the urban subway are arranged in the subway rail line map;
determining a plurality of rail sections from a subway rail in a subway rail line map; the length of the steel rail section is the preset steel rail section length; the length of the steel rail section can be, for example: 3 meters;
determining and drawing a plurality of inspection frames comprising a plurality of steel rail sections from a subway steel rail line map based on inspection frame conditions; the inspection frame is a minimum surrounding rectangle of a plurality of steel rail sections contained in the inspection frame;
