Description

Intelligent distribution method and system for legal case agent
Technical Field
The invention relates to the technical field of legal case agents, in particular to an intelligent distribution method and system of legal case agents.
Background
When people encounter legal disputes and further seek lawyer agents for help, the following important factors are often concerned: whether lawyers are professional, whether lawyer-skilled areas match dispute cases that i encounter, how well lawyers are served, whether lawyers have enough time and energy to help i solve problems and solve doubts, how quickly i can get the most appropriate lawyer information through, and the like, which are the core complaints most concerned by the masses as clients in legal agencies or entrusting relationships.
On the other hand, the interest of lawyer groups is closely related to the appeal of the client, and is different. The reason is that the total number of lawyers in China is less than one hundred thousand at present, and the number of lawyers in every ten thousand is only 2.17 by combining the population cardinality of China; at the same time, lawyers in the united states have up to 37 per thousand. The shortage of lawyers' resources creates a certain imbalance in supply and demand, and the case agents and consultants that lawyers receive daily often exceed their workload, while for revenue considerations, lawyers are generally biased towards higher value, i.e., higher target rate cases; meanwhile, the difference of law enforcement years, case processing experience and the like can also cause case resource allocation difference in law groups to a certain extent: some highly qualified, well-known attorneys may receive a large number of premium sources, while some new attorneys who have just entered may receive less than nominal amounts and less than nominal amounts. The above two points make attorneys pay more attention when taking over the agent cases: whether the consultation or agency requirement can be finally converted into a formal consignment contract, how large the nominal amount of the case is, whether I still need to accept the simple consultation as a qualified attorney, and how I can obtain more and better case resources as a new attorney.
In the process of reconciling different value requirements of clients and lawyers, the development of internet technology enables the channels of client searching lawyers to be gradually shifted from offline to online. In recent years, a large number of case agent matching platforms mainly based on lawyer diversion function appear, and the general method for processing legal case matching by the platforms is as follows: on the user side, the user manually filters and screens own agent lawyers according to conditions such as case types, lawyer regions, working years, places and places, but general users are difficult to distinguish the two types of cases due to the fact that the screening items are too professional, for example, "labor disputes" and "labor disputes" in dispute types;
on the lawyer side, active inquiry of users is attracted relatively passively by means of showing out personal information, areas of excellence, past cases and the like on websites. Obviously, the matching between the client and the lawyer depends on self selection of both parties, but due to the asymmetry of information and the problem of cold start, the user cannot necessarily find the most suitable lawyer with sufficient time to serve the user; the new law enforcement officers still face the problem of few cases. The platform only performs basic functions of lawyer review, exhibition position control and the like, does not perform matching, and is difficult to ensure the service quality.
By means of the platforms, partial researchers and manufacturers try to make lawyer recommendations according to the characteristics of the dispute cases. The specific method generally comprises the following steps: according to the dispute type selected by the user or the dispute type obtained by case description analysis and prediction, lawyers are screened from a law teacher database (some methods are searched from the law teacher database of the user, and other methods are used for more simply extracting lawyer information from public official document data), and the screening conditions mainly surround the relatively static characteristics of the lawyers such as the regions, the practical years, the areas with strong proficiency and the like. The recommendation has the advantages that lawyers with better matching and higher winning rates can be given in a certain range, but the defects are obvious: 1. the situation that a new lawyer is in the position behind a recommendation list due to short practice period and few agent cases cannot be solved; 2. lawyer information extracted from the referee document is inaccurate or has changed; 3. the mere use of lawyer scores for recommendation results in high scoring lawyers being continually recommended for good quality case sources, exacerbating the problem of uneven case source distribution, and failing to ensure that lawyers have sufficient time and energy to better serve the customer.
Therefore, in summary, the existing method and lawyer recommendation technology for realizing case agent matching by using a website with lawyer diversion as a main function have the following disadvantages in the process of dealing with increasing legal case agent distribution and appeal:
firstly, the disadvantages in the process of lawyer recommendation or characterization of lawyer features are:
1. the existing lawyer diversion websites and lawyer recommendation technologies adopt a mode of scoring and recommending purely according to lawyer static information (such as regions, years, adequacy fields and the like), mainly rely on lawyers to submit during authentication or actively update in the follow-up process, and inevitably meet the risks of accuracy and timeliness; meanwhile, some indexes capable of assisting in representing the service capability of the lawyer at the current moment, such as the indexes of the working load of the lawyer and the like, are not included in the characteristic representation;
2. the current lawyer recommendations are generally only part of the offline calculation, and the client feedback information in the service process is not returned online to the lawyer recommendation, and the risk points generated are as follows: if online consultation or other communication links exist, lawyers have difficulty in feeding back and influencing the recommendation ranking of the lawyers in real time if some illegal professional principles or behaviors which are not friendly to clients appear.
Secondly, for the client side, the prior art generally suffers from these drawbacks in the process of screening lawyers:
1. the existing lawyer diversion website generally needs a client to manually fill out screening conditions, wherein the expression of part of the screening conditions is difficult to understand for general public with non-legal specialties, for example, the meaning of the type of dispute, which type of dispute my case should belong to, what the territorial representation of the lawyer represents, which cases need local lawyer agents, which cases can be handled in different places, and the like, which options of over-specialized expression increase the cost of the client for using the website or the system;
2. the conventional few lawyer recommendation technologies adopt prediction of case dispute types according to client case description and by combining machine learning or deep learning technologies, so that the cost of knowing professional options of a client is reduced, but the defect that information loss to a certain extent is caused when the lawyer recommendation is carried out only according to the case description exists, such as regional information, identity information, emotion information and the like of the client, which are actually taken as factors to be considered in the lawyer matching or recommendation process exists.
Finally, in the process of matching, matching or distributing the attorney side and the client side:
1. the prior art generally only makes 1-to-N pairing, namely one client comes in and matches and recommends the most appropriate set of lawyers for selection, but as the industry develops and the website traffic increases, more than one client logs in and visits at the same time, at this time, an M-to-N optimization matching problem exists, namely how to assign M users to N lawyers and optimize the target of the whole assignment process, for example, the time and energy of the qualified lawyers are limited, if M users are assigned to the best lawyers, a situation that some users need to queue in a queue occurs, however, if some users have high instantaneity requirements on responses, whether the users can be assigned to suboptimal lawyers is a better choice.
2. The existing technology does not control the fatigue degree aiming at the service capability of a lawyer, and under the condition that the lawyer receives too many orders within a period of time, the continuous order dispatching is actually reduced, otherwise, the time and the service quality of the lawyer cannot be ensured;
3. new attorneys face the problem of cold starts in both existing attorney diversion websites and recommendation technologies: for a new attorney who has a short practice period, few past cases, relatively good ability and plenty of time, it is difficult to obtain better recommendation ranking and information exposure in the prior art, which also affects the acquisition of more and better case sources.
