All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Please refer to fig. 1, which is a flowchart illustrating an embodiment of a method for constructing a semantic ontology-based lottery knowledge base according to the present application, including the following steps:
s100, performing semantic analysis on the Guangdong color porcelain elements according to the Guangdong color porcelain patterns, and constructing a modeling primitive language of a semantic body;
it should be noted that, semantic analysis is performed on the elements of the wide color porcelain, which may be to perform semantic analysis on the forms, colors, elements and themes of the wide color porcelain, explore and extract semantic connotations and emotional elements of the wide color porcelain, and perform association, divergence and recombination on the semantics after acquiring specific semantics.
In the application, 5 modeling primitive languages are constructed by the expression ontology, specifically: classes, relationships, functions, axioms, and instances. The set of categories is the term and concept related to the field of the colored porcelain, such as classification, process, manufacturing method, etc. The classification of the categories can be divided into primary concepts such as a plate, a dish, a basin, a bowl, a cup, a pot, a cup, a bottle, a painting and the like in a specific embodiment, and the classification under the primary concepts is classified into secondary concepts; the concept represents a set of objects, the relationship pair represents a set of object tuples, and the concept adopts a framework structure and comprises a name of the concept, a set of relationships with other concepts and a description of the concept by semantics.
It should be noted that the relationship includes an object relationship attribute and a value relationship attribute, where the object relationship attribute is used to describe the relationship between classes.
The function is used for describing the relationship between the concept and the data type; axioms (axioms) is a restricted description of classes and attributes in the body of the Guangdong color porcelain; an instance is a representation of an object.
S200, acquiring explicit knowledge and implicit knowledge of the colorful porcelain knowledge according to a knowledge management principle;
it should be noted that explicit knowledge means that explicit knowledge can be expressed in language, text, body, diagram, etc., i.e., knowledge that can be understood by others through expression; implicit knowledge is the knowledge that needs to be further understood through the outer layers. Ontologies also exhibit different hierarchies in describing real-world knowledge. In the application, the library corresponding to the implicit knowledge comprises a knowledge base, wherein the knowledge base comprises semantic ontology knowledge information and corresponding pattern information; the library corresponding to the explicit knowledge comprises a case sample library, and the case sample library comprises images, texts, audios and videos of the colorful porcelain.
It should be noted that, in the present application, the existing relatively stable knowledge resources are described formally by using general knowledge and domain knowledge, and the dynamic knowledge aims at the interactive learning of the knowledge by the user and the fact that dynamically occurs in reality, such as the formal description of the entity object of the wide-color porcelain; secondly, aiming at the current situation that knowledge covers the culture application field, knowledge system construction is carried out on the knowledge in the application field, the field terms and the incidence relation are described formally, and cross-field sharing of the knowledge is realized; and finally, establishing a relation among knowledge of different languages according to the multi-language characteristics of the knowledge, realizing the mapping association of cross-language knowledge, and gradually refining the constructed concept of the multi-dimensional semantic ontology description from abstraction to concrete according to different application ranges. The concept of the general knowledge and the concept of the domain knowledge are mainly expressed as a relatively stable hierarchical structure, and the domain attribute of the concept is increased while the concept of the domain knowledge inherits the attribute of the general concept. The dynamic knowledge mainly describes the fact that the reality dynamically occurs, the knowledge may be directly from the upper general knowledge and the domain knowledge, and the new knowledge connotation is dynamically added according to the characteristics of the application scene, and the dynamic knowledge is mainly expressed as a dynamic network structure.
Step S300, dividing the library corresponding to the explicit knowledge and the implicit knowledge into a general knowledge body, a dynamic knowledge body and a domain knowledge body;
it should be noted that the general ontology includes general concepts: the history, process, color and border of the porcelain with the colorful porcelain. The Guangxi porcelain also can consider selecting universal words in the field of porcelain, and enriches the available vocabulary, thereby constructing a knowledge system of a certain number of universal concepts.
Domain ontology refers to knowledge that describes a particular application domain and discipline. The domain knowledge ontology has strong subject dependence, such as the fields of industry, art and the like. The method is characterized in that the commonly recognized concepts in the field are required to be clarified for constructing the field knowledge, and the concepts and the relation among the concepts are represented by a formalized model, so that the common understanding of the field knowledge is realized. For example, the ceramic belongs to the field of industry, and the manufacturing process of the wide-color porcelain taking the ceramic as the raw material can search a more appropriate concept vocabulary in the industrial term.
The dynamic knowledge body takes the actual requirements of users as traction, the construction process utilizes the existing knowledge and network data resources and is automatically completed by a machine, and the dynamic knowledge body mainly focuses on objects in specific tasks, events or activities and the relation among the objects. For example, in the personalized learning process of the wide-color porcelain, some dynamic knowledge can be selected according to the learning dynamics and the input labels of the user and the information about the wide-color porcelain, so that the construction of the body model of the wide-color porcelain is further assisted. The dynamic knowledge has strong expandability, can continuously track, actively responds to new dynamics, and realizes the dynamic expansion and maintenance of the knowledge.
S400, fusing a general knowledge ontology, a dynamic knowledge ontology and a field knowledge ontology into a colorful porcelain knowledge model;
and S500, constructing a semantic retrieval model for personalized learning based on the Guangdong porcelain knowledge model.
It needs to be explained that a practical and easy-to-use retrieval mode needs to be provided after the Guangdong color porcelain knowledge model is built, the semantic retrieval model is built based on the Guangdong color porcelain knowledge model, the work of a semantic retrieval search engine is no longer restricted by the face of a request sentence input by a user, the real intention behind the sentence input by the user is captured, and the search is carried out according to the real intention, so that a search result which best meets the requirement of the user is more accurately returned to the user. The semantic search fully mines semantic information contained in webpage document information, simultaneously converts retrieval requirements of users into corresponding semantic representations, distinguishes and infers the semantic representations based on the domain ontology, understands user query from semantic level, and returns results inferred based on the ontology to the users. The semantic retrieval and recommendation based on the ontology can help the user to continuously adjust the retrieval vocabulary of the user and change the retrieval strategy so as to obtain the most relevant knowledge, effectively make up for the deficiency of keyword retrieval, and remarkably improve the accuracy of the query result.
The search process of the semantic search model, which may be referred to in fig. 2, includes:
step S510, acquiring a user request, and extracting a semantic label according to the user request;
step S520, performing information reasoning according to the semantic label to perform extended query on the Guangdong porcelain knowledge model;
step S530, the search result is filtered and pushed to the user.
In a specific embodiment, after performing semantic search to obtain a search result, a user may perform personalized learning on the search result and perform a personalized learning process through a semantic search model, with reference to fig. 3, including:
step S531, generating image description according to the semantic retrieval result;
and step S532, extracting and reusing the configuration of the wide color porcelain according to the image description.
