Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered 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.
It should be noted that the embodiments of the present invention and the technical features in the embodiments may be combined with each other without collision.
Fig. 1 is a schematic diagram of main modules of an article screening device according to an embodiment of the present invention.
As shown in fig. 1, an article screening apparatus 100 according to an embodiment of the present invention includes a screening condition generation module 101 and a target article determination module 102, the screening condition generation module 101 and the target article determination module 102 being uncoupled; wherein:
a screening condition generating module 101, configured to receive at least one target screening indicator selected from a plurality of screening indicators, and first arithmetic logic corresponding to each target screening indicator; generating article screening conditions according to the target screening index and the first arithmetic logic, and sending the article screening conditions to the target article determining module;
a target item determination module 102 for receiving item screening conditions; acquiring information of a plurality of articles to be screened, and respectively executing the following steps for each article to be screened: determining an index value of at least one target screening index from information of the articles to be screened; and determining whether the object to be screened meets the object screening condition according to at least one index value so as to determine whether the object to be screened is a target object or a non-target object.
In the embodiment of the invention, the target screening index is selected from a plurality of screening indexes, each screening index is formulated according to a preset coding rule, different screening indexes indicate different concerns of information of the articles to be screened, for example, a good score indicates concerns of quality of the articles to be screened, a near 30-day achievement traffic indicates concerns of sales heat of the articles to be screened, and the like. Therefore, different target screening indexes can be selected from different screening indexes, different article screening conditions are generated, and different target articles are screened out, so that different article screening requirements are better met.
Specifically, as shown in fig. 2, the preset encoding rule for the screening index includes a tag theme, a tag type and an index code, where the tag theme includes a theme of a USER, a commodity and a corresponding field thereof (for example, a field corresponding to the USER is a USER, a field corresponding to the commodity is an ITM), the tag type includes a statistical type, a rule type, an algorithm type and a field corresponding to the algorithm type (01, 02, 03 respectively), and the index code is used for uniquely identifying the screening index and includes a commonly used receiving address, a purchasing power and the like and a field corresponding to the purchasing power (for example, a field corresponding to the commonly used receiving address is 0001, and a field corresponding to the purchasing power is 0002). According to the preset coding rule in fig. 2, a plurality of screening indexes as shown in fig. 3 can be generated, wherein the first column is the index name of the screening index, the second column is the index code of the screening index, the third column is the field description of the screening index, and the fourth column is the reservoir name or table name to which the screening index belongs. For example, the screening index of "good score" is coded as "comm_01_0004", which indicates that the screening index belongs to the subject of "commodity comment", and is a statistical label, and the corresponding information source is the commodity itself. Fig. 4 is a schematic diagram of a filtering index metadata table, where the filtering index metadata table is used to store fields related to each column in fig. 3 and related information thereof, for example, the first column in fig. 3 is "index name" in fig. 4, the corresponding field is a quota_name, and the type of the field is string type.
In the embodiment of the invention, a plurality of screening indexes can be expanded according to the new article screening requirement so as to meet the new article screening requirement. At this time, the screening condition generation module 101 is further configured to: receiving a code corresponding to the newly added screening index; determining whether the codes accord with preset coding rules or not; if yes, the newly added screening index is written into the existing screening index.
For example, if there is a new item screening requirement that involves an index "number of bids" that is not shown in fig. 3, the developer may take the index as a new screening index and encode the new screening index on the front page, and then click the "save" button to save the new screening index "number of bids" to the screening index shown in fig. 3. At this time, the front end may send the code corresponding to the newly added screening index to the back end, and the back end determines whether the code meets the preset coding rule in fig. 2: if so, the newly added screening index 'bid amount' and the codes thereof are written into the existing screening index (i.e. figure 3), if not, the writing can be refused and the prompt about the code error can be displayed on the front page.
In the embodiment of the invention, the first operation logic comprises a required value and an operator corresponding to the target screening index, the required value and the operator are configured by a user, and in the case that the target screening index is a plurality of target screening indexes, the user also needs to configure a second operation logic among the plurality of target screening indexes. At this time, the screening condition generation module 101 is further configured to: receiving a second arithmetic logic between a plurality of target screening indexes; and generating article screening conditions according to the target screening index, the second operation logic, the required value and the operator.
Specifically, the multiple screening indexes in fig. 3 may be displayed on the front-end page, the user selects the target screening index from the multiple screening indexes in fig. 3 according to the article screening requirement, and if the target screening index is multiple, the user needs to configure second operation logic between the multiple target screening indexes on the front-end page, where the second operation logic includes and operation and/or operation. The user also needs to configure a corresponding operator and a required value for each target screening index on the front-end page, wherein the operators comprise greater than, less than or equal to each other. The user completes configuration of the front-end page and sends the configuration result to the back-end, and the back-end generates article screening conditions according to the received configuration result (namely, the target screening indexes, second operation logic among a plurality of target screening indexes, operators and requirement values corresponding to each target screening index configuration).
As can be seen from the above description, since the target screening index is selected by the user and the requirement value and the operator corresponding to the target screening index are configured by the user, if the condition of the selected item changes, the item screening condition corresponding to the changed condition of the selected item can be generated by changing the selected target screening index or by changing the configured requirement value and/or operator, so that the code in the script does not need to be modified by a developer as in the prior art, and the risk of error in script operation caused by modification of the script is reduced.
In an embodiment of the present invention, the item screening conditions may further include: one or more item screening sub-conditions, wherein each item screening sub-condition corresponds to an operation identifier (including a retention identifier or a rejection identifier), and the operation identifier is also configured on a front-end page by a user. At this time, the configuration result that the user completes the configuration of the front-end page and sends the configuration result to the back-end further includes an operation identifier, and the filtering condition generating module 101 is further configured to: receiving operation identifiers corresponding to each article screening sub-condition, wherein the operation identifiers comprise retention identifiers or rejection identifiers; generating an article screening sub-condition according to the target screening index, the second operation logic, the required value, the operator and the operation identifier; item screening conditions are generated based on the one or more item screening sub-conditions.
In the embodiment of the invention, the configuration result of the user is split by the back end according to the preset rule list and the index rule detail list. As shown in fig. 5, the preset rule table is used for recording a field, a field name, a field type, and a value caliber (the value caliber is a value range), for example, the field name of the rule_type field includes 1 retention rule (i.e., a rule whose operation identifier is a retention identifier), 2 rejection rule (i.e., a rule whose operation identifier is a rejection identifier), and 3 other rules (other rules need to be determined for the option method, and are rarely used), the field type is of the int type, and the value caliber is not preset. Fig. 6 is a schematic diagram of a preset index rule list, where the index rule list is used to record the rule ID in fig. 5 and the index codes, index requirement values, index operators, index logic (and logic, or logic) of the corresponding screening indexes. By means of separation of the preset rule list and the index rule detail list, operation identifiers configured by a user can be separated from other contents (required values, operators, second operation logic and the like) configured by the user, so that the contents are not affected, and functional isolation is achieved.
In this embodiment of the present invention, when generating the article screening condition, the screening condition generating module 101 may integrate the configuration result of the user (the operation identifier configured by the user in this case) with the rule table shown in fig. 5 as a main table according to the target screening index, the second operation logic, the required value, the operator, and the operation identifier, and the target screening index, and the code, etc. obtained according to fig. 3 and 4, the required value, the operator, and the second operation logic, etc. obtained according to fig. 6, and write the target screening index, the code, etc. into the main table, so as to generate the article screening condition table shown in fig. 7 (the table is limited in space, fig. 7 is only a part of the content in the example of the article screening condition table), where each row of the article screening condition table is one article screening sub-condition. And the rule integration broad table corresponding to the item screening condition table is shown in fig. 8.
For example, as shown in fig. 7, the rule_id (rule ID as known from fig. 8) of the item screening sub-condition of the first line of fig. 7 is 1; rule_desc (i.e., description of the item screening sub-conditions as seen in fig. 8) is "affordable good target user screening rules-retention rules"; rule_biz_type (known as service type from fig. 8) is 1, which indicates that the service type is crowd; rule_type (operation identifier as known from fig. 8) is 1, which indicates that the operation identifier corresponding to the item screening sub-condition is a retention identifier, and the item screening sub-condition is a retention rule; rule_method (rule method as understood from fig. 8) is 1, illustrating that the item screening sub-condition is crowd-target user defined; exe_cycle (i.e., calculation period as seen in fig. 8) is m, which indicates the calculation period of the item screening sub-condition in months; rule_method_flag (as can be seen from fig. 8, i.e., marking type) is 1, indicating that the item screening sub-condition acts on the screening index; the quota_id (i.e., the index code of the screening index as seen in fig. 8) is u_01_0001, and the screening index in the item screening sub-condition is "user common receiving ground level" as seen in fig. 3 and 4.
In an embodiment of the present invention, the target item determination module 102 is further configured to: judging whether the index value corresponding to each target screening index meets the requirement value and the operator corresponding to the target screening index or not according to at least one target screening index, and obtaining at least one judging result; under the condition that the judging result is one, determining whether the object to be screened meets the object screening sub-condition according to the judging result; and under the condition that the judging results are multiple, determining whether the articles to be screened meet the article screening sub-conditions according to the judging results and the second operation logic.
In the embodiment of the present invention, the target article determining module 102 may obtain the information of the plurality of articles to be screened according to the preset merchandise tag width table as shown in fig. 9. The information of the articles to be screened obtained at this time is the information corresponding to the preset commodity label in fig. 9.
In an embodiment of the present invention, the target item determination module 102 is further configured to: for each article to be screened, determining an index value of at least one target screening index from information of the article to be screened. Specifically, after the information of the plurality of articles to be screened is obtained, the index VALUEs can be matched in a KEY-VALUE format aiming at the target screening index in the article screening condition, wherein KEY is the target screening index, and VALUE is the index VALUE corresponding to the target screening index.
In the embodiment of the present invention, after determining, for each item to be screened, the target item determining module 102 determines the index value of at least one target screening index from the information of the item to be screened, a table "item to be screened+target screening index+index value" including a plurality of items to be screened, where each item to be screened corresponds to at least one target screening index, and each target screening index corresponding to each item to be screened has an index value is obtained. In a preferred embodiment of the present invention, the target item determination module 102 may be further configured to: performing row-by-row operation on the table of the to-be-screened object, the target screening index and the index value by using the following statement:
LATERAL VIEW EXPLODE(SPLIT(KEY-VALUE,’,’))
in an embodiment of the present invention, the target item determination module 102 is further configured to: the item screening condition table shown in fig. 7 is associated with the "item to be screened+target screening index+index value" table using the following index codes:
T1.QUOTA_ID＝T3.DATA_QUOTA_ID
in an embodiment of the present invention, after associating the item screening condition table with the "item to be screened+target screening index+index value" table, the target item determination module 102 may be further configured to: dividing the article screening sub-conditions in the article screening condition table into two branches according to second operation logic (AND logic or OR logic), then determining whether the index value in the table of 'article to be screened + target screening index + index value' meets the first operation logic (namely the operator and the requirement value) corresponding to the corresponding target screening index in the article screening condition table, and marking. If the article screening sub-condition is AND logic, marking as 0 when the index value meets the first operation logic, and if the article screening sub-condition is OR logic, marking as 1 when the index value meets the first operation logic, thereby obtaining an identifier (0 or 1) corresponding to each target screening index corresponding to the article to be screened.
After the identifier corresponding to each target screening index corresponding to each article to be screened is obtained, whether the article to be screened meets the article screening sub-condition or not can be determined according to the identifier corresponding to each target screening index corresponding to each article to be screened. Specifically, if the item screening sub-condition is AND logic, the summary value of the identifiers is equal to 0, which indicates that the item screening sub-condition is met, and is greater than 0, which indicates that the item screening sub-condition is not met; if the item screening sub-condition is OR logic, the identified aggregate value equal to 0 indicates that the item screening sub-condition is not satisfied, and a value greater than 0 indicates that the item screening sub-condition is satisfied.

In such an embodiment, the computer program can be downloaded and installed from a network via the communication portion 1409 and/or installed from the removable medium 1411. The above-described functions defined in the system of the present invention are performed when the computer program is executed by a Central Processing Unit (CPU) 1401.
The computer readable medium shown in the present invention may be a computer readable signal medium or a computer readable storage medium, or any combination of the two. The computer readable storage medium can be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or a combination of any of the foregoing. More specific examples of the computer-readable storage medium may include, but are not limited to: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the context of this document, a computer readable storage medium may be any tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device. In the present invention, however, the computer-readable signal medium may include a data signal propagated in baseband or as part of a carrier wave, with the computer-readable program code embodied therein. Such a propagated data signal may take any of a variety of forms, including, but not limited to, electro-magnetic, optical, or any suitable combination of the foregoing. A computer readable signal medium may also be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device. Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to: wireless, wire, fiber optic cable, RF, etc., or any suitable combination of the foregoing.
The flowcharts and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams or flowchart illustration, and combinations of blocks in the block diagrams or flowchart illustration, can be implemented by special purpose hardware-based systems which perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
The modules involved in the embodiments of the present invention may be implemented in software or in hardware. The described modules may also be provided in a processor, for example, as: a processor includes a screening condition generation module and a target item determination module. The names of these modules do not constitute limitations on the module itself in some cases, and for example, the screening condition generation module may also be described as "a module that generates item screening conditions".
As another aspect, the present invention also provides a computer-readable medium that may be contained in the apparatus described in the above embodiments; or may be present alone without being fitted into the device. The computer readable medium carries one or more programs which, when executed by a device, cause the device to include: receiving at least one target screening index selected from a plurality of screening indexes, and a required value and an operator corresponding to each target screening index; generating article screening conditions according to the target screening index, the required value and the operator; acquiring information of a plurality of articles to be screened, and respectively executing the following steps for each article to be screened: extracting at least one index value corresponding to at least one target screening index one by one from the information of the articles to be screened; and determining whether the object to be screened meets the object screening condition according to at least one index value so as to determine whether the object to be screened is a target object or a non-target object.
According to the technical scheme provided by the embodiment of the invention, the screening condition generation process and the target object determination process are mutually separated, so that the object screening process can be completed by using one set of codes, repeated development is not needed, and the workload of developers is reduced.
The above embodiments do not limit the scope of the present invention. It will be apparent to those skilled in the art that various modifications, combinations, sub-combinations and alternatives can occur depending upon design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
