Notes:

A semantic graph is a type of data structure used to represent the meaning or semantics of natural language text. It is also called a semantic network, which is a directed or undirected graph consisting of vertices, which represent concepts, entities, or events and edges, which represent relationships between them. These relationships can be semantic, syntactic, or pragmatic. The nodes of the graph can be labeled with attributes such as category, properties, and actions that are used to define the meaning of the concepts. The edges can be labeled with relations such as is-a, part-of, causes, and used-for. Semantic graphs are commonly used in natural language processing, information retrieval, and knowledge representation to represent the meaning of text and to enable the inference of new knowledge from existing knowledge. The term semantic graphs can be used to represent multiple semantic graph, and semantic network can be used to represent multiple semantic graphs.

A semantic graph is a form of knowledge representation that is used to express the meaning or semantics of natural language text. It is a directed or undirected graph consisting of vertices, which represent concepts, entities, or events and edges, which represent semantic relations between these concepts. The edges represent the relationships between the concepts and are labeled with relations such as is-a, part-of, causes, and used-for. It is also common that semantic networks are represented as semantic triples, which consist of a subject, predicate and object, representing a fact about the relationship between two entities. It is used in different fields such as natural language processing, information retrieval, and artificial intelligence to represent knowledge and enable the inference of new knowledge.

An undirected graph is a type of graph where the edges connecting the vertices have no direction, they are bidirectional. This means that if there is an edge between vertex A and vertex B, then there is also an edge between vertex B and vertex A. In other words, the relationship between the two vertices is symmetric. This contrasts with a directed graph, also called a directed network, where the edges have a direction, meaning that the relationship between two vertices is not symmetric, for example, if there is an edge from vertex A to vertex B, there may not be an edge from vertex B to vertex A.

Knowledge graph is a more general representation of knowledge and it is a collection of entities, relationships, and attributes that are used to represent the knowledge in a specific domain. The entities in a knowledge graph are typically represented as nodes, and the relationships between them are represented as edges. The edges can be labeled with the type of relationship, such as “is-a”, “part-of”, “causes”, etc. The attributes are used to store additional information about the entities, such as properties and actions. Knowledge graphs can be used for various purposes such as natural language processing, information retrieval, and recommendation systems.
