Detailed Description
In order to solve the technical problems in the prior art, a first aspect of the technical solution shown in the embodiments of the present application shows a method for constructing a page workflow based on text processing, referring to fig. 1, where the method includes:
s101, displaying an operation frame page, wherein the operation frame page comprises: an operation interface, the operation interface displaying a set of algorithm components;
starting an operation frame page, wherein the operation frame page comprises: the operation interface displays an algorithm component set;
the operation frame page is shown in fig. 2. In the technical solution shown in the embodiment of the present application, the operation frame page includes: an operation interface, a display interface; the operation interface comprises: a main flow creation area and an algorithm component collection display area.
S102, establishing a main flow, acquiring a target component selected by a user, and determining a call flow of the target component;
the main flow creation area is used for creating a main flow; the main flow comprises the following steps: a start node and an end node; the user can define the application name of the created page workflow in advance before the main flow is created, wherein the application name can be used as a label so that the subsequent personnel can find the page workflow.
After the creation of the initial node is completed, the attribute corresponding to the initial node is displayed in the attribute display area, and the user can set the attribute of the initial node in the attribute display area. Illustrating: the application name is: calculating the similarity of two addresses and corresponding attributes: parameter name-addri of the starting node, type-java. Lang. String of the parameter, parameter description-address text to be compared 1.
The user can set the attribute of the end node in the attribute display area: the return field-similarity, type of parameter-java. Lang. String, parameter description-similarity value.
According to the technical scheme, through setting the parameter description of the starting node, in the subsequent page workflow application process, a certain guiding effect can be achieved on the user input parameters, for example: parameter description-address text to be compared 1. The user knows that the input parameters are text according to the parameter description. The setting of the parameter description of the end node can play a certain guiding role on the learning result of the user in the subsequent page workflow application process, for example: parameter description-similarity value. And the user knows the similarity of the address as a result of the page workflow output according to the parameter description.
It should be noted that, in the practical application process, a starting node may correspond to at least one input parameter, for example: and calculating the page workflow of the similarity of the two addresses, wherein the initial node corresponds to two input parameters, one input parameter is the address text 1 to be compared, and the other input parameter is the address text 2 to be compared. For a page workflow of keyword extraction, the start node corresponds to an input parameter.
S103, constructing a page workflow, wherein the page workflow comprises a main flow, a target component and a call flow of the target component;
the algorithm component set display area is used for displaying an algorithm component set, and each algorithm component in the technical scheme shown in the embodiment of the application corresponds to a document processing algorithm or a document processing mode.
For example, for the word segmentation algorithm component, the corresponding document processing manner is: the document is cut into words. In the practical application process, there are more cutting modes for cutting a document into a plurality of words, for example: (1) The forward maximum matching method is to divide a word from left to right. For example: "do not know what you are saying" this sentence is the result of the segmentation using forward maximum matching: "do not know, you, what is said". (2) The reverse maximum matching method is "do not know what you are saying" the result after the reverse maximum matching method is split: "do not, know what you are, reverse max matching is right to left. (3) Shortest path word segmentation, that is, a segment of words requiring the least number of words to be cut. "do not know what you are speaking" shortest path word splitting means that the word that splits that sentence into is the least. "do not know what you are, what is said" this is the shortest path word splitting method, and only 3 words are split. And (4) a bidirectional maximum matching method. The document processing algorithm to which the word segmentation algorithm component corresponds may be designated as one of the specific word segmentation algorithms described above. In the word segmentation application process, the shortest path word segmentation method is widely applied, and a document processing algorithm corresponding to the shortest path word segmentation method is stored in a word segmentation algorithm component.
In the practical application process, in order to ensure the accuracy of the output result of the page workflow constructed by the technical scheme shown in the embodiment of the application, the embodiment of the application shows a method for configuring the page workflow in a personalized manner aiming at different application scenes. Specifically, each algorithm component has a component attribute corresponding to the algorithm component, and when a user selects a certain algorithm component, the component attribute corresponding to the corresponding algorithm component is displayed in the attribute display area. Wherein the component attributes include: specific manner of implementation of the algorithm components.
Illustrating: the algorithm components are as follows: the word segmentation algorithm component is correspondingly realized in the following specific modes: a forward maximum matching method, a reverse maximum matching method, a shortest path word segmentation method and a bidirectional maximum matching method. When the user selects the word segmentation algorithm component, the forward maximum matching method, the reverse maximum matching method, the shortest path word segmentation method and the bidirectional maximum matching method are displayed on the page in the form of a drop-down frame, and the user selects the target component attribute according to the requirement.
Acquiring a target component attribute selected by a user, and calling a text processing algorithm corresponding to the target component attribute; and replacing the text processing algorithm corresponding to the selected component with the text processing algorithm corresponding to the target component attribute to generate the target component.
In the word segmentation application process, the shortest path word segmentation method is widely applied, and a document processing algorithm corresponding to the shortest path word segmentation method is stored in a word segmentation algorithm component.
The user A selects a word segmentation algorithm component as a target component in the process of constructing the word segmentation page data stream, and the word segmentation page data stream constructed by the user A divides a text ' don't know what you are speaking ' into: "do not know what you are saying.
In the construction process of a user, when the user selects a word segmentation algorithm component, the component attribute of the word segmentation algorithm component corresponding to the word segmentation algorithm component is displayed in a form of a drop-down frame: a forward maximum matching method, a reverse maximum matching method, a shortest path word segmentation method and a bidirectional maximum matching method. For the application scene of the user, the maximum matching method can ensure the cutting accuracy, the user selects the forward maximum matching method as the target component attribute, and the text processing algorithm corresponding to the forward maximum matching method is called; and replacing a default text processing algorithm of the word segmentation algorithm component by using the text processing algorithm corresponding to the forward maximum matching method, and generating a new target component of the word segmentation algorithm component.
According to the technical scheme shown in the embodiment of the application, a user selects a document processing algorithm matched with an application scene according to different application scenes, so that the accuracy of a page workflow output result constructed by the technical scheme shown in the embodiment of the application is ensured. In addition, when the user configures the page workflow, the user can flexibly decide the specifically adopted algorithm for document processing according to the actual application scene, and even if the user does not have an algorithm base, the user does not understand programming, the user can flexibly and conveniently configure the page workflow.
In order to further simplify the construction process of the page workflow, the technical scheme shown in the embodiment of the application shows a generation mode of the call flow of the algorithm component.
Specifically, the component attributes further include: request parameters of the algorithm component and return parameters of the algorithm component; wherein the request parameters of the algorithm component include: request return field of parameter, parameter type, and field specification; the return parameters of the algorithm component include: a return field for the return parameter, the parameter type, and the field specification.
At least one target component is provided, and the specific implementation process of determining the call flow of the target component is as follows when the number of the target components is greater than 1:
acquiring a request parameter type of the target component and returning the parameter type;
and determining the call flow of each target component according to the request parameter type and the return parameter type of the target component.
FIG. 3 is a page workflow for computing the similarity of two addresses, from which it can be seen that the workflow contains three classes of target algorithm components. The three types of target algorithm components are respectively: two are word segmentation algorithm components, two are filter word algorithm components, and one is similarity algorithm component. Acquiring a request parameter type of the target component and returning the parameter type; the request parameter type of the word segmentation algorithm component is text, and the return parameter type is words; the request parameter type of the stop word algorithm component is a word, and the return parameter type is a word; the request parameter type of the similarity algorithm component is a word, and the return parameter type is a number.
Firstly, determining that a return parameter type of a starting node is text, and a request parameter adapted to the address is a word segmentation algorithm component, and correspondingly, a downstream node of the starting node is the word segmentation algorithm component. The return parameter types of the word segmentation algorithm component are words, the request parameter types of the filter word algorithm component and the similarity algorithm component are words, and at the moment, the call flow of the component can be determined by means of the return parameter types of the filter word algorithm component and the return parameter types of the similarity algorithm component. And determining an upstream node of the ending node according to the request parameter type of the ending node. The return parameter type of the similarity algorithm component is a numerical value, and it can be determined that the similarity algorithm component is an upstream node of the end node, and correspondingly, a downstream node of the word segmentation algorithm component is a stop word algorithm component, and a downstream node of the stop word algorithm component is a similarity algorithm component. The call flow of the page workflow for determining the similarity of the addresses is as follows: the method comprises the steps of a starting node, a word segmentation algorithm component, a word filtering algorithm component, a similarity algorithm component and an ending node.
In practical application, a user configures a call flow between algorithm components through configuring the types of request parameters of the algorithm components and returning the types of parameters, so that the purpose of flexible configuration is achieved.
When the user configures the page workflow, the user can flexibly decide the specifically adopted algorithm components and the call flow between the algorithm components according to the actual application scene, and even if the user does not have an algorithm foundation, the user does not understand programming, the user can also flexibly and conveniently configure the page workflow.
For a word segmentation algorithm component, the component attributes also include: extracting the components of the sentence.
If the component attribute of the component of the extracted sentence is selected, for a sentence 'I go to Beijing zoo';
after labeling the part-of-speech sentence components: i- (subject), go- (predicate), beijing zoo- (object).
At this time, since the target component attribute selected by the user is a component of the extracted sentence. Correspondingly, the specific mode of the algorithm component implementation of the word filtering algorithm component can be selected to realize word filtering through the components of sentences.
For example, if the specific implementation of the algorithm component of the filtering word algorithm component can choose to implement the filtering of the words by the subjects, then me- (subjects), de- (predicates), beijing zoo- (objects), the request parameter is input into the filtering word algorithm component, and the output return parameter is "de- (predicates), beijing zoo- (objects)".
If the specific mode of the algorithm component implementation of the filtering word algorithm component can be realized through objects, I- (subjects), I- (predicates) and Beijing zoo- (objects) are selected, the request parameters are input into the filtering word algorithm component, and the output return parameters are I- (subjects) and I- (predicates).
In the actual application process, the user can select the corresponding target component attribute according to the actual service requirement, and the selection of the target parameter attribute can be realized to meet the requirements of different users.
Optionally, in order to further simplify the construction process of the page workflow and reduce the selection range of the user in the selection process, the technical scheme shown in the embodiment of the application shows a generation manner of the call flow of the algorithm component.
Typically, the algorithm component set includes hundreds to thousands of algorithm components, and as the service is continuously expanded, corresponding new algorithm components are continuously added into the algorithm component set, the user selects a target algorithm component from the huge algorithm component set, which is a huge workload. According to the technical scheme, a first algorithm component set is screened out through the type of the return parameter corresponding to the upstream algorithm component (also called as an upstream node) or the type of the return parameter corresponding to the starting node, the first algorithm component set comprises at least one first algorithm component, and the return parameter type of the first algorithm component is matched with the request parameter type of the target component. The user selects the target algorithm component in the first algorithm component set, the selection range of the user in the selection process is reduced, the generation rate of the page workflow is relatively improved, and meanwhile, the construction process of the page workflow is relatively simplified.

If the target component is one, the call flow of the corresponding target component is: a start node, a target algorithm component, and an end node;
under the condition that the number of the target components is larger than 1, the specific implementation process of determining the call flow of the target components is as follows:

Illustrating: the initial node returns a text as a parameter type, and the corresponding first algorithm component set is as follows: the word segmentation algorithm component, the angle and half angle conversion algorithm component, the simplified and repeated conversion algorithm component, the messy code processing algorithm component and the like are a series of algorithm components with text request parameter types, and a user only needs to select a target algorithm component from the first algorithm component set according to requirements. In an embodiment, the target algorithm component selected by the user is a word segmentation algorithm component, the return parameter types of the obtained word segmentation algorithm component are words, and the corresponding first algorithm component set is as follows: and disabling the word filtering algorithm component, the word frequency statistics algorithm component and a series of algorithm components with the request parameter types of words, and the like, and continuing until the downstream node of the target algorithm component is an end node.
