There are numerous sub-theories related to semantic memory that have developed since Tulving initially posited his argument on the differences between semantic and episodic memory; an example is the belief in hierarchies of semantic memory, in which different information one has learned with specific levels of related knowledge is associated.
In computer science, semantic knowledge management is a set of practices that seeks to classify content so that the knowledge it contains may be immediately accessed and transformed for delivery to the desired audience, in the required format.
A semantic network, or frame network is a knowledge base that represents semantic relations between concepts in a network. This is often used as a form of knowledge representation . It is a directed or undirected graph consisting of vertices , which represent concepts , and edges , which represent semantic relations between concepts , [ 1 ...
Semantics studies meaning in language, which is limited to the meaning of linguistic expressions. It concerns how signs are interpreted and what information they contain. An example is the meaning of words provided in dictionary definitions by giving synonymous expressions or paraphrases, like defining the meaning of the term ram as adult male sheep. [22]
Semantic processing can also be affected by various health conditions such as semantic aphasia, which may be a result of a unilateral stroke to the left inferior frontal gyrus and posterior middle temporal gyrus. Individuals with semantic aphasia may struggle with controlled semantic retrieval.
Some authors regard semantic search as a set of techniques for retrieving knowledge from richly structured data sources like ontologies and XML as found on the Semantic Web. [2] Such technologies enable the formal articulation of domain knowledge at a high level of expressiveness and could enable the user to specify their intent in more detail ...
Our brains have distinct mechanisms—from semantic memory for factual knowledge (like knowing that 2+2=4) to episodic memory for recalling personal experiences (like remembering the moment you ...
This includes world knowledge, object knowledge, language knowledge, and conceptual priming. Semantic memory is distinct from episodic memory , which is the memory of experiences and specific events that occur during people's lives, from which they can recreate at any given point. [ 6 ]
