Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
FIG. 1 is a schematic diagram of the main flow of a method of asset filtering according to an embodiment of the invention. As shown in fig. 1, as an embodiment of the present invention, the method for asset filtering may include:
and 101, judging whether the residual filtering amount is larger than or equal to a preset amount threshold value, if so, acquiring the assets to be sold by adopting a jumping rule, and if not, acquiring the assets to be sold by adopting a sequence rule.
In this step, whether to acquire the assets for sale using the skip rule or the sequential rule may be determined by whether the remaining filtering amount is sufficient. If the remaining filter amount is sufficient, the assets for sale may be obtained using a skip rule, and if the remaining filter amount is insufficient, the assets for sale may be obtained using a sequence rule.
Specifically, an amount threshold may be preset as a basis for determining whether the remaining filtering amount is sufficient, that is, determining whether the remaining filtering amount is greater than or equal to the preset amount threshold, if so, obtaining the assets to be sold by using a skip rule, and if not, obtaining the assets to be sold by using a sequence rule.
It should be noted that, after determining the acquisition rule for acquiring the assets for sale, the system configuration of the distribution protocol may be modified to initialize the filtering parameters of the current assets, for example, whether the acquisition of the assets for sale is according to the skip rule or the sequence rule, and other system level parameters.
As another embodiment of the present invention, acquiring assets for sale using a skip rule includes: according to the fact that the asset amount of the assets to be sold is from large to small, the assets to be sold are sorted in a descending order mode to obtain an ordered asset list; after jumping with jumping degree S, acquiring the first N assets to be sold, wherein the asset amount of the assets in the ordered asset list is less than or equal to the maximum asset amount; the maximum asset amount is the asset amount of the first asset to be sold in the ordered asset list or the minimum asset amount of the N assets to be sold acquired at the previous time, and S and N are positive integers larger than zero.
For example, in this embodiment, first, using the advantage of the database sequential index, the assets to be sold are sorted in descending order according to the smaller asset amount of each asset to be sold, and an ordered list of assets to be sold is created, where 9 assets to be sold are listed in the ordered list, and the records are as follows.
Then, when the assets to be sold are obtained in the first step, the first three assets to be sold with the asset amount of 20000 or less are obtained, the result set IDs are 1201, 101 and 1211, and the corresponding asset amounts are 20000, 18510 and 18500 respectively. And 18500 is recorded as the maximum asset amount for the next acquisition of the asset for sale.
Then, when acquiring the assets for sale for the second time, after jumping with the jump degree of 3 (namely, jumping over the 4 th record to the 6 th record, wherein the IDs of the records are 1301, 456 and 86 respectively), acquiring the first 3 assets for sale with the asset sum of 18500 or less in the ordered asset list, and acquiring result set IDs of 50, 23 and 78, wherein the corresponding asset sums are 8500, 8400 and 500 respectively. And 500 is recorded as the maximum asset amount for the next acquisition of assets for sale.
Similarly, when the assets to be sold are obtained for the third time, after the jump with the jump degree of 3 is performed (i.e. 7 th to 9 th records are skipped, and the IDs of the records are 499, 400 and 385 respectively), the first 3 assets to be sold with the asset amount less than or equal to 500 in the ordered asset list are obtained, which is not described again in the embodiments of the present invention.
Note that, in the above embodiments, the details are described by taking S ═ N ═ 3 as an example, but in other embodiments of the present invention, the value of S, N may be different or the same. For example, S is 500, N is 1000; 1000 for S, 300 for N; and S ═ N ═ 800, and the like, which are not limited in this embodiment of the present invention, and are not described again in this embodiment of the present invention.
Optionally, if the result set is empty, the asset amount of the first asset for sale in the ordered asset list may be reset to the maximum asset amount, and a new round of execution of the skip filtering algorithm may be initiated again.
It should be noted that, in the above embodiments, the assets to be sold are sorted in descending order according to the smaller asset amount of the assets to be sold, and in other embodiments, the assets to be sold may also be sorted in ascending order according to the smaller asset amount of the assets to be sold. Correspondingly, in the embodiment of ascending order, the first N assets to be sold whose asset amounts in the ordered asset list are greater than or equal to the minimum asset amount are obtained, which is not described again in the embodiment of the present invention.
As another embodiment of the invention, acquiring assets for sale using a sequence rule comprises: according to the fact that the asset amount of the assets to be sold is from large to small, the assets to be sold are sorted in a descending order mode to obtain an ordered asset list; acquiring the first M assets to be sold, of which the asset amount is less than or equal to the maximum asset amount, in the ordered asset list; the maximum asset amount is the asset amount of the first asset to be sold in the ordered asset list or the minimum asset amount of the M assets to be sold acquired in the previous time, and M is a positive integer larger than zero.
For example, in this embodiment, first, using the advantage of the database sequential index, according to the asset amount of each asset to be sold from large to small, the following ordered list of assets to be sold is created, where the following records are recorded:
then, when the assets to be sold are obtained in the first step, the first three assets to be sold with the asset amount of 20000 or less are obtained, the result set IDs are 1201, 101 and 1211, and the corresponding asset amounts are 20000, 18510 and 18500 respectively. And 18500 is recorded as the maximum asset amount for the next acquisition of the asset for sale.
Then, when the to-be-sold assets are obtained for the second time, the first three to-be-sold assets with the asset sum smaller than or equal to 18500 are obtained, the result set IDs are 1301, 456 and 86, and the corresponding asset sums are 17500, 16500 and 14500 respectively. And 14500 is recorded as the maximum asset amount for the next acquisition of the asset for sale.
Similarly, when the to-be-sold assets are obtained for the third time, the first three to-be-sold assets with the asset amount less than or equal to 14500 are obtained, and the embodiment of the present invention is not described again.
It should be noted that, in the above embodiments, M ═ 3 is taken as an example for detailed description, and in other embodiments of the present invention, M ═ 500, M ═ 800, M ═ 1200, and the like, which are not limited in this embodiment of the present invention, and are not repeated again.
It should be noted that, in the above embodiments, the assets to be sold are sorted in descending order according to the smaller asset amount of the assets to be sold, and in other embodiments, the assets to be sold may also be sorted in ascending order according to the smaller asset amount of the assets to be sold. Correspondingly, in the embodiment of ascending order, the first M pieces of assets to be sold whose asset amounts are greater than or equal to the minimum asset amount in the ordered asset list are obtained, which is not described again in the embodiment of the present invention.
And 102, filtering the assets to be sold based on the filtering and screening conditions to obtain the assets to be sold which accord with the filtering and screening conditions, and updating the residual filtering amount according to the asset amount corresponding to the assets to be sold which accord with the filtering and screening conditions.
Different protocols correspond to different filtering and screening conditions, such as credit rating of a user, single amount range of the assets, total amount of the current asset filtering, remaining total amount of the current asset filtering and the like, and all the different protocols can be used as the filtering and screening conditions.
In the step, each asset is processed in a circulating mode, each asset is filtered in a screen mode according to the filtering and screening conditions, and if any filtering and screening condition is not met in the filtering process, the current asset to be sold is directly skipped, and the next asset to be sold is filtered. And only the assets for sale which meet all the filtering and screening conditions are deducted from the residual filtering amount.
Therefore, the assets to be sold which accord with the filtering and screening conditions are obtained through layer-by-layer screening, the asset amount of the assets to be sold which accord with the filtering and screening conditions and the residual filtering amount of the current time are recorded, the filtering amount of the current time (namely the asset amount of the assets to be sold) is subtracted from the residual filtering amount of the current time, the filtering amount is updated to the residual filtering amount of the next time, and the termination condition of the circular filtering is ensured.
As still another embodiment of the present invention, step 102 may comprise: filtering the assets to be sold based on filtering and screening conditions aiming at each asset to be sold, and if the assets to be sold accord with the filtering and screening conditions, subtracting the asset amount of the assets to be sold from the remaining filtering amount of the current time and updating the remaining filtering amount of the assets to be sold into the remaining filtering amount of the next time; and circularly filtering each asset for sale until the residual filtering amount is less than or equal to zero.
And 103, marking the assets to be sold which meet the filtering and screening conditions.
In this step, the assets to be sold that meet the filtering and screening conditions are subjected to batch marking and updating, and filtering time, filtering state and protocol information are identified.
It should be noted that, in step 103, the assets for sale that meet the filtering and screening condition also meet the requirement that the remaining filtering amount of the next time obtained by subtracting the asset amount of the assets for sale from the remaining filtering amount of the current time is greater than or equal to zero.
According to the various embodiments, the technical scheme that whether the residual filtering amount is larger than or equal to the preset amount threshold value or not is judged, if yes, the assets to be sold are obtained by adopting the jumping rule, and if not, the assets to be sold are obtained by adopting the sequence rule is adopted, so that the problem that the assets to be sold are obtained randomly and singularly is solved. That is, in the prior art, the acquisition of the assets for sale has randomness, so that the filtering amount is uncertain, and the problems of unstable factors and unpredictability exist for the filtering efficiency. The invention carries out ordered sequencing according to the asset amount of the assets to be sold and obtains the assets to be sold in a sequence or jump mode, thereby ensuring the high efficiency of asset filtering and the average property of asset dispersion. Therefore, under the conditions of abundant assets and shortage of assets, different filtering modes can be effectively adopted to carry out efficient asset filtering, the assets are orderly filtered, and the proportion distribution of the assets and money is effectively adjusted. In addition, in the process of asset filtering, the progress and trend of current asset filtering can be clearly counted.

step 207, processing one of the plurality of assets for sale obtained in step 205 or step 206;
step 208, judging whether the piece of assets to be sold meets all filtering and screening conditions, if so, executing step 209, and if not, executing step 211;
step 209, subtracting the asset amount of the to-be-sold asset from the remaining filtering amount of this time, and updating the remaining filtering amount of this time (as the remaining filtering amount of the next filtering);
step 210, judging whether the updated residual filtering amount is larger than zero; if yes, go to step 207; if not, indicating that the residual filtering amount is insufficient, and ending;
step 211, circularly processing each asset for sale obtained in step 205 or step 206 until all assets for sale are processed or the residual filtering amount is less than or equal to zero;
step 212, marking the assets for sale which are obtained in the step 207-210 and meet the filtering and screening conditions in batches.
