Problems solved by technology
[0009] So far, methods for developing ontology from natural language texts exist, but most of the constructed ontologies are static structured ones, and their semantic search has made progress on the basis of previous keyword-based searches, but lacks dynamics. and procedural, and incapable of semantic search involving process
For the process ontology, there are currently related researches, but it is basically based on the manual construction of domain experts, and the constructed process ontology cannot be automatically updated, and cannot achieve sustainability
After searching, there is no report on the automatic construction of process ontology, especially the automatic construction of process ontology for domain problem solving

Embodiment Construction
[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, but they are not further limitations on the present invention.
[0032] A method for mining domain process ontology from natural language text provided by the present invention is characterized in that: comprising the following steps:
[0033] A. Create a process ontology model. By parsing the text, find logical segments, extract words expressing concepts, words expressing the relationship between concepts and concepts, and axioms, theorems, definitions and inferences in logical segments, and create classes, attributes, and The relationship between classes;
[0034] B. Instantiate the created process ontology model;
[0035] C. The above process ontology model and the instantiated process ontology model are represented by RDF triples and stored in the AG knowledge base.
[0036] Step A includes the following sub-steps:
[0037] A1. Analyze the text a...

The invention discloses a method for mining domain process ontology from natural language texts. The method includes: A, creating a process ontology model; B, instancing the created process ontology model; and C, displaying the created process ontology model and the instanced process ontology model via an RDF (resource description framework) triad and saving the same in an AG (Allegro Graph) knowledge base. The invention further discloses an intelligent searching method based on the process ontology model. Semantic search is performed according to the process ontology model and received text data. Via the method for mining the domain process ontology from the natural language texts, the process ontology model capable of updating automatically is created, and the created process ontology model is saved in the AG knowledge base so as to facilitate the semantic search.
Description
technical field [0001] The present invention relates to ontology; more specifically, to a method for mining domain process ontology from natural language text. Background technique [0002] In this specification, the following are used in the indicated meanings unless otherwise specified: [0003] - "Ontology": Ontology is a clear and detailed description of a certain conceptual system (conceptual expression, conceptualization, conceptualization system or conceptualization process). Ontology, as a modeling tool that can describe the conceptual model of an information system at the semantic and knowledge levels, has quickly become a research hotspot in the field of information systems and artificial intelligence after it was proposed. Ontology is the basis for the formal description of important entities, attributes, processes and their relationships in the field, and can provide a basic structure for the construction of knowledge bases; The practical application in this fi...
