First embodiment
Referring to fig. 1, a schematic flow chart of a method for managing external data of a bank based on an ES according to this embodiment is provided, where the method includes the following steps:
s101: and acquiring external data of the target bank to be managed, and extracting attribute information of the external data of the target bank.
It should be noted that, because the conventional file management system used at present is slow, long in time consumption, and poor in performance, the existing file management system is mainly used for accurately retrieving the file query, and the fuzzy search support through keywords such as the file name and the author name is less, which results in poor user experience.
Therefore, in this embodiment, in order to increase the speed of retrieving the external data of the bank and implement the fuzzy retrieval of the user, for the bank, it is first required to obtain the external data of the target bank to be managed and extract the attribute information of the external data of the target bank, so as to implement the effective management of the external data of the bank through the subsequent steps S102 to S103.
S102: and importing the attribute information of the external data of the target bank into the ES, and generating an attribute information index corresponding to the attribute information of the external data of the target bank.
In this embodiment, after the target bank external data to be managed is acquired in step S101 and the attribute information of the target bank external data is extracted, the attribute information of the target bank external data may be further sorted and processed, and then may be introduced into the ES in batch, and an attribute information index corresponding to the attribute information of the target bank external data is generated.
In a possible implementation manner of the embodiment of the present application, the attribute information of the external data of the target bank includes text information such as a file name, an author name, and summary information, and further, the specific implementation process of this step S102 includes the following steps a1-a 2:
step A1: and importing the file name, the author name and the summary information into the ES, and performing word segmentation processing on the file name, the author name and the summary information to obtain word segmentation results corresponding to the file name, the author name and the summary information.
Step A2: and generating a keyword index corresponding to the file name, the author name and the summary information according to the word segmentation result.
In this implementation, after extracting the attribute information such as the file name, the author name, and the summary information of the external data of the target bank, the present or future word segmentation method may be further used to perform word segmentation processing on the attribute information such as the file name, the author name, and the summary information to obtain word segmentation results corresponding to the attribute information such as the file name, the author name, and the summary information, and further, an index (defined as a keyword index herein) corresponding to the attribute information such as the file name, the author name, and the summary information may be generated according to the word segmentation results.
In another possible implementation manner of the embodiment of the application, the target bank external data is newly added bank external data, and further, the specific implementation process of the step S102 includes the following steps B1-B2:
step B1: and extracting attribute information of the newly added external data of the bank.
Step B2: and introducing the attribute information of the newly added external data of the bank and the attribute information of the external data of the historical bank into the ES together, and generating an attribute information index corresponding to the attribute information of the newly added external data of the bank and the attribute information of the external data of the historical bank.
In this implementation, if the target bank external data is the newly added bank external data, after the newly added bank external data (such as credit investigation information of the client, blacklist information in a mobile phone record of the client, property information and the like) is obtained, the attribute information of the newly added bank external data, such as a file name, an author name, abstract information and the like, is extracted, then, the attribute information of the newly added bank external data and the attribute information of the historical bank external data can be jointly imported into the ES, and an attribute information index corresponding to the attribute information of the newly added bank external data and the attribute information of the historical bank external data is generated, so as to execute the subsequent step S103 and implement distributed management of the attribute information index.
S103: and receiving a retrieval condition input by a user, wherein the retrieval condition comprises attribute information of data outside the target bank.
In this embodiment, after the step S102 is performed to import the attribute information of the external data of the target bank into the ES and generate the attribute information index corresponding to the attribute information of the external data of the target bank, the search condition including the attribute information of the external data of the target bank, which is input by the user, may be further received. For example, the user may input information of a file name, a special surname, a cell name, a building number, and the like, which are independent or combined, as a search condition, so as to implement the fuzzy search through the subsequent step S104.
S104: and performing fuzzy retrieval on the external data of the target bank according to the retrieval conditions and the attribute information index corresponding to the attribute information of the external data of the target bank to obtain a retrieval result.
In this embodiment, after the attribute information index corresponding to the attribute information of the external data of the target bank is generated in step S102, and the retrieval condition input by the user is received in step S103, the fuzzy retrieval or the precise retrieval may be further performed on the external data of the target bank according to the retrieval condition and the attribute information index corresponding to the attribute information of the external data of the target bank, so as to obtain the retrieval result.
For example, the following steps are carried out: take the property information in the following table as an example:
typically, external data from banks is typically stored in semi-structured text form, as follows:
if the traditional file management system is used for management, the information is usually converted into a structured format for storage or direct full-text retrieval, and the retrieval speed is low and the efficiency is low.
However, according to the method of the embodiment of the present application, through the above steps S101 to S104, by using the elasticsearch, the VALUE information of the upper record can be used to construct an index, and after performing the word segmentation processing on the index, the fuzzy search can be performed on the keyword information (i.e., the attribute information), and the search result is fed back according to the matching degree. In addition to supporting basic accurate search, the present application can also implement fuzzy search for keywords "rose" and "jadeite" to obtain search results.
In summary, in the method for managing external data of a bank based on an ES according to this embodiment, first, external data of a target bank to be managed is obtained, attribute information of the external data of the target bank is extracted, then, the attribute information of the external data of the target bank is imported into the ES, an attribute information index corresponding to the attribute information of the external data of the target bank is generated, and then, a retrieval condition input by a user is received, where the retrieval condition includes the attribute information of the external data of the target bank; and then, fuzzy retrieval can be carried out on the external data of the target bank according to the retrieval conditions and the attribute information index corresponding to the attribute information of the external data of the target bank, so that a retrieval result is obtained. Therefore, the bank external data can be effectively managed based on the ES, so that the retrieval speed of the bank external data is improved, the fuzzy retrieval of the user is realized, and the user experience is improved.
