Description
Technical Field
The invention relates to the technical field of business information, in particular to a method and a device for acquiring quotation information.
Background
The trade market of the financial institution is an OTC (Over-the-counter market) market, which is a market for inquiring quotes, and the general trade mode is that one party of the trade issues quote information to the whole market or fixed objects. In addition, the advertisement type text quotation information is mainly distributed and sent through a transparent RM, a Tencent QQ and a WeChat, so that the following problems are caused:
(1) the readability of text information is poor. The transaction quotation relates to a variety, a code, a deadline, a transaction direction, a transaction price, a transaction amount and other multiple elements, the elements are simply listed in a text form in the current quotation presentation mode, the content of the transaction quotation information is difficult to reflect visually, a transactor needs to spend a long time to read, understand and react, the transaction efficiency is obviously reduced, and the transaction opportunity is easy to miss;
(2) and (4) screen swiping phenomenon, which causes difficulty in tracking information. After the market is opened in the trade market, the price bees of the opponents are gathered, and the screen refreshing phenomenon is generated. When the local trader gets an indication of today's trading, it must roll back several or even hundreds of pages to see the opponent's advertisement he wants to trade and then trade with it. This creates an inconvenience in information lookup.
(3) New and old information is mixed. Financial markets are changing constantly, so that a quotation party withdraws quotations, revises the quotations and sends the quotations again for many times, the information which is refreshed is probably old, and the information which is seen by the quotation party is old and new and old because IM software cannot distinguish which information is covered by the old information, and the information which is viewed by the quotation party is necessary to be distinguished one by one with strength.
(4) The quotation information is scattered and difficult to compare quickly. Some mechanisms in the quotation have volume and price, and some mechanisms do not have price, so when a trader wants to find a better price, the trader needs to continuously turn pages back and forth to compare the prices.
Because of the above problems, after the quoted party obtains the information, the quoted party needs to digest the information one by one and then see whether the party has corresponding commodities or funds to trade with the corresponding commodities or funds. Because one organization faces hundreds of opponents, several advertisement type quotations appear every minute, the analysis of contents and the search of contents are both troubled, namely, the quotation information of each opponent is compared, and a proper counterparty is screened.
The investment of financial transaction, especially fixed income commodity transaction, is a competitive and highly time-efficient work, and traders need to pay close attention to market quotation information, find the optimal price among a plurality of quotation information according to own trading strategies, and reach a trading agreement with a trading opponent. However, based on the aforementioned limitations, the current quotation forms and tools are difficult to meet the business requirements, directly affect the trading efficiency, and further restrict the profitability of the trading organization. Therefore, it is desirable to provide a quote information acquiring technology that is simple, efficient and meets the current market demand.

Example 2
Fig. 2 is a flowchart of a method for acquiring quotation information according to embodiment 2 of the present invention, and as shown in fig. 2, the method for acquiring quotation information according to the embodiment of the present invention includes the following steps:
201. and acquiring text information for describing the text format of the quotation information.
Specifically, the text information may include contents of chinese characters, numbers, english, and the like. Because the quoted information advertisement of financial transaction of goods like fixed income is generally issued by instant communication tools, the information in the quoted information advertisement exists in text format.
The offer information generally includes a financial commodity category name, a financial item term, a financial item price, a financial item quantity, a transaction request, etc., and the offer information includes offer information that differs according to the type of the offer information advertisement.
To further illustrate the effect of the embodiment of the present invention, fig. 3 is a schematic diagram of a bid information advertisement, which is common in the prior art, and as shown in fig. 3, the text information content includes both names or acronyms of different transaction categories and corresponding amount of data, transaction requirements, and the like. In addition, some quotation information advertisements also contain financial commodity recommendation terms for attracting other interests, and it is seen that the formats and habits of different quotation information advertisements issued by different counterparties are also different. In the face of such diverse and complex pricing information, the inefficiency is evident if it is merely through logging, screening, comparison or some other conventional means of processing. Since the text information containing the quotation information is mostly expressed in a text format, in addition to the text format, other formats such as pictures (such as screenshots and the like) may exist in some cases, but the unusual formats are few, so that the text information in the text format can be directly acquired, and the efficiency of the step of acquiring the quotation information is higher.
It should be noted that, step 201 obtains text information in a text format for describing the offer information, and the process may be implemented in other ways besides the ways described in the above steps, and the specific ways are not limited in the embodiment of the present invention.
202. Classifying the character information according to a preset weight rule to obtain a classification result; the classification result includes training data satisfying a first weight probability, test data satisfying a second weight probability, and evaluation data satisfying a third weight probability. Specifically, the classification method comprises the following steps:
after text information used for describing quotation information is obtained and before the quotation information is processed, the text information is classified according to a preset weight rule and divided into training data meeting a first weight probability, inspection data meeting a second weight probability and evaluation data meeting a third weight probability. The training data is used for carrying out subsequent learning or training on the quotation information data, the inspection data is used for inspecting the model obtained by the training, and the evaluation data is used for evaluating the effect of processing by using the obtained model data. The preset weighting rule can be set according to specific situations, and for example, can be set as follows: a first weighted probability of 60%, a second weighted probability of 20%, and a third weighted probability of 20%. Through the operation, data with different purposes can be prepared according to needs, early-stage preparation is made for a later-stage data training model, and classified training data, inspection data and evaluation data can better provide guarantee for training of the later-stage model when preset weight rules are better distributed or set.
It should be noted that, in the step 202, the text information is classified according to the preset weight rule to obtain the classification result, besides the manner described in the above step, the process may also be implemented in other manners, and the specific manner is not limited in the embodiment of the present invention.
203. And (4) performing label definition and modeling on the character information to generate a training set.
Specifically, the text information in the general quoted advertisement includes the financial commodity category, the specific different transaction price or amount, and the like. Certainly, a plurality of offer advertisements need to be distinguished according to the types of commodities, different text paragraphs belonging to different types need to be distinguished, at this time, names of commodities of different types need to be respectively labeled, one commodity type corresponds to one label, and variables corresponding to the labels are defined and modeled to generate a training set. Illustratively, the labeling process of the classification of the commodity categories may be referred to as "commodity separation labeling", and the process of commodity separation is as follows:
(1) defining variables: defining a plurality of variables y1, y2 and … yn, wherein n represents a variety expressed by characters in n rows;
(2) labeling is respectively carried out according to different situations: in a Training Set (Training Set), a line belonging to a line of characters of one variety is marked with Yes (y1 ═ 1), and the rest is No (y2 ═ y3 ═ … ═ yn ═ 0); in a Training Set, a row belonging to two lines of characters of one variety is marked with Yes (y2 ═ 1), and the rest is No (y1 ═ y3 ═ … ═ yn ═ 0); (4) and so on.
In addition, the annotation definition and modeling can also be performed on the transaction elements in the quotation information, and exemplarily, the following processes can be performed:
(1) tagging of transaction elements: labeling the digital content in the transaction element, wherein the label can be a period, a price and a quantity and is used for more conveniently identifying the learning result;
(2) defining attributes for performance indicators under different labels: defining attributes according to the financial commodity of the same industry, such as y1 being the same industry deposit, y2 being the agreement deposit, … y11 being the purchase, y12 being the sale, … y13 being the price, y14 being the quantity, y15 being the term …
(3) Defining the attribute value: and analyzing each variety advertisement, marking the corresponding attribute with 1 and marking the rest with 0.
Because the quotation text information comprises a plurality of transaction elements such as commodity types, time limit, price, quantity and the like and a plurality of commodity attribute indexes such as the same-industry deposit, protocol deposit, purchase and the like, different elements are identified, defined and modeled for the purpose of meeting machine learning language or serving for later data processing, and the training of a later model is facilitated.
It should be noted that, in step 203, the text information is labeled, defined and modeled to generate a training set, and besides the above-described manner in the step, the process may be implemented in other manners, and the specific manner is not limited in the embodiment of the present invention.
204. And carrying out advertisement category classification processing and transaction element data processing training including transaction element classification processing, sorting, screening and charting processing on the training set through a preset neural network model to obtain a target neural network model.
After step 203 is completed, a training set is obtained, and based on the training set, the following two aspects are trained through a preset neural network model:
(1) and (3) advertisement category classification processing: based on the commodity separation labeling, defining and modeling completed in step 203, training is performed according to preset training rules through a preset neural network model, and finally classification processing of quoted advertisement categories is achieved.
(2) Transaction element data processing including transaction element classification processing, sorting, screening and charting processing:
a. the transaction element classification processing refers to classifying various transaction elements in the offer information of the offer advertisement, and can be trained through a preset neural network model based on the transaction element labeling, definition and modeling completed in the step 203, so that the transaction element classification processing is finally realized;
b. the transaction element data including sequencing, screening and charting processing can be carried out on the transaction element information, so that the finally presented quotation information is more visual, diversified and clear, and better serves transaction personnel; in fact, the process may be performed not in the step of training the neural network, but after the training process is completed, and the invention is not limited thereto.
The steps a and b may be performed in a sequential manner, a parallel manner or an alternative manner, and the present invention is not limited thereto. In practice of training and acquiring the offer information, it is preferable that the advertisement classification process is performed on advertisement information of a plurality of different categories, and then the transaction element classification process of the commodity category is performed on each single category after the classification process. The operation makes the training process more orderly, and the quotation information data meeting the requirements can be more effectively obtained.
205. According to the new text information for describing the quotation information, the target neural network model is utilized to carry out advertisement category classification processing and transaction element data processing including transaction element classification processing, sorting, screening and charting processing, so as to obtain the quotation information.
After the target neural network model is obtained, when new text information used for describing quotation information is obtained, the target neural network model is utilized to carry out advertisement category classification processing and transaction element data processing including transaction element classification processing, sorting, screening and charting processing on the quotation information, and the quotation information is obtained. The specific processing steps are similar to the advertisement category classification processing and the transaction element data processing steps including the transaction element classification processing, sorting, screening and charting processing in the foregoing steps, and the related contents of the foregoing steps can be referred to, and are not described again here.
The quotation information of the quotation information is finally obtained, namely, the quotation information is obtained, the showing mode of the quotation information can be various according to different data processing processes, exemplarily, fig. 4 is a schematic diagram of the quotation information obtained by the quotation information obtaining method provided by the embodiment of the invention, as shown in fig. 4, effective information is obtained from complicated quotation advertisement text information through the series of processing processes of the quotation information obtaining method, and the effective information is converted into a standard expression form, so that the method is clear and greatly improves the efficiency of traders for obtaining the effective quotation information.
206. And checking and evaluating the target neural network model through the checking data meeting the second weight probability and the evaluation data meeting the third weight probability, adjusting model parameters of the target neural network model according to the checking result and the evaluation result, and obtaining a final neural network model so as to obtain new quotation information by using the neural network model. In order to obtain the optimal neural network model, i.e. the optimal model parameters, the target neural network model is checked and evaluated based on the check data meeting the second weight probability and the evaluation data meeting the third weight probability obtained in step 202, so as to obtain the final neural network model, and then new quotation information is obtained by using the neural network model.
207. According to the new character information for describing the quotation information, the final neural network model is utilized to carry out advertisement category classification processing and transaction element data processing including transaction element classification processing, sorting, screening and charting processing, so as to obtain the quotation information.
Specifically, after the final neural network model is obtained, when new text information for describing offer information is obtained, the neural network model is used for carrying out advertisement category classification processing and transaction element data processing including transaction element classification processing, sorting, screening and charting processing on the offer information to obtain the offer information. The specific processing steps are similar to the advertisement category classification processing and the transaction element data processing steps including the transaction element classification processing, sorting, screening and charting processing in the foregoing steps, and the related contents of the foregoing steps can be referred to, and are not described again here.
The quotation information of the quotation information is finally obtained through the further optimized neural network model, namely, the quotation information is obtained, the showing mode of the quotation information can be various according to different data processing processes, and the effective information is obtained from the complicated quotation advertisement character information through the series of processing processes of the quotation information obtaining method and is converted into a standard showing mode, so that the efficiency of obtaining the effective quotation information by traders is clear and greatly improved.
In addition, in order to obtain a better training neural network model, training set data for training can be added by various methods, for example, label identification or definition can be performed by multiple synonyms or synonyms, and by setting various label setting or definition rules, samples are artificially added so as to increase the learning effect, for example, "out" can be replaced by selling, and a new batch of samples is generated.
