How is the Semantic Web related to the existing web?
The Semantic Web is a vision about an extension of the existing World Wide Web, which provides software programs with machine-interpretable metadata of the published information and data. In other words, we add further data descriptors to otherwise existing content and data on the Web.
What is Semantic Web in psychology?
A semantic network, or frame network, is a network which represents semantic relations between concepts. 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.
What the Semantic Web can represent?
The semantic web model is that a URI dereferences to a document which parses to a directed labeled graph of statements. The statements can have URIs as prameters, so they can may statements about documents and about other statements.
What is the main aim of Semantic Web?
The Semantic Web aims to enrich the Web with a layer of machine-interpretable metadata so that computer programs can predictably derive new information. This goal will require the development of metadata syntax and vocabularies, and the creation of metadata for lots of Web pages.
What is knowledge representation in Semantic Web?
The Semantic Web integrates concepts from knowledge representation and reasoning with markup languages based on XML. The Resource Description Framework (RDF) provides the basic capabilities to define knowledge-based objects on the Internet with basic features such as Is-A relations and object properties.
Which is also known as the Semantic Web?
The Semantic Web, sometimes known as Web 3.0, is an extension of the World Wide Web through standards set by the World Wide Web Consortium (W3C). The goal of the Semantic Web is to make Internet data machine-readable.
How semantic networks can be used for knowledge representation?
In Semantic networks, we can represent our knowledge in the form of graphical networks. This network consists of nodes representing objects and arcs which describe the relationship between those objects. Semantic networks can categorize the object in different forms and can also link those objects.
What is the relation between knowledge & intelligence?
Knowledge is the collection of skills and information a person has acquired through experience. Intelligence is the ability to apply knowledge. Just because someone lacks knowledge of a particular subject doesn’t mean they can’t apply their intelligence to help solve problems.
Why is knowledge representation important?
Knowledge representation is not just storing data into some database, but it also enables an intelligent machine to learn from that knowledge and experiences so that it can behave intelligently like a human.
What is knowledge representation explain with example?
Definition. Knowledge representation refers to the technical problem of encoding human knowledge and reasoning ( Automated Reasoning) into a symbolic language that enables it to be processed by information systems.
What do you understand by representation of knowledge explain the characteristics of a good knowledge representation?
A good knowledge representation system must have properties such as: Representational Accuracy: It should represent all kinds of required knowledge. Inferential Adequacy: It should be able to manipulate the representational structures to produce new knowledge corresponding to the existing structure.
What are the characteristics of knowledge representation?

What is difference between knowledge representation and knowledge acquisition?
Knowledge acquisition was obtained by tapping the expertise of clinical nurse specialists who were able to articulate the elements present in their diagnostic decisions. Knowledge representation was achieved using a commercially-available software package.
What is the difference between procedural knowledge and declarative knowledge?
Declarative knowledge is conscious; it can often be verbalized. Metalinguistic knowledge, or knowledge about a linguistic form, is declarative knowledge. Procedural knowledge involves knowing HOW to do something – ride a bike, for example. We may not be able to explain how we do it.
What are the various ways of representing knowledge in knowledge base?
Of the different ways, there are 4 main approaches to knowledge representation in artificial intelligence, viz. simple relational knowledge, inheritable knowledge, inferential knowledge, and procedural knowledge—each of these ways corresponding to a technique of representing knowledge discussed above.
Which of the following is a knowledge representation technique used to represent knowledge?
Propositional logic is a knowledge representation technique in AI.
How is knowledge represented in knowledge base of an expert system?
The forms of knowledge representation typically used in expert systems are: structured objects (frames, semantic networks, object-oriented principles), rules (if-then) and logic (predicate, proposi- tional).
What is the difference between knowledge based system and expert system?
The knowledge base represents facts about the world, often in some form of subsumption ontology. The inference engine represents logical assertions and conditions about the world, usually represented via IF-THEN rules. an expert system is a computer system that emulates the decision-making ability of a human expert.
Which components are required to to develop knowledge base system explain each component?
There are three main components of a knowledge based system: Knowledge Base: The actual knowledge stored as ontologies in the system. Inference Engine: The backend component of a KBS that applies logic rules (as assertions and conditions) to the knowledge base to derive answers from it.
