 Example one
 figure 1 It is a flowchart of the steps of the method for generating a knowledge graph provided by this embodiment. The method generates an initial knowledge graph based on the initial knowledge graph framework and seed knowledge sets that include the attributes and association relationships between named entity types (step S110). Specifically, a common knowledge classification system in the industry can be used to perform the named entity Classification, and establish a binding framework for various types of petroleum exploration knowledge according to the knowledge form and the conceptual categories of various entity objects (project category, geological object category, and geological age category). This constraint framework stipulates whether there are (potential) association relationships between named entity types in multiple dimensions, and vividly and intuitively displays the relationships among various knowledge in the field of petroleum expl...
 Example two
 image 3 It is a schematic structural diagram of the system for generating a knowledge graph provided by this embodiment. The system includes an initialization unit, a type judgment unit (not shown in the figure), a single image-text knowledge item recognition unit, a graphic-text collection knowledge item recognition unit, and a correction unit.
 Among them, the single graphic knowledge item recognition unit includes a single text knowledge discovery and extraction unit and a single image knowledge discovery and extraction unit. The unit of knowledge discovery and extraction in a single text consists of two consecutive modules: a named entity recognition module in a single text and a named entity association relationship discovery module in a single text.
 The main purpose of the named entity recognition module in a single text is to recognize named entities involved in a single text. Based on the existing professional dictionaries in t...
