	Semantic network - Wikipedia, the free encyclopedia
		A semantic network is often used as a form of knowledge representation.
		It is possible to represent logical descriptions using semantic networks such as the Existential Graphs of Charles S. Peirce or the related Conceptual Graphs of John F. Sowa.
		In the 1960s to 1980s the idea of a semantic link was developed within hypertext systems as the most basic unit, or edge, in an semantic network.

	Semantic Research: Semantic Networks
		Semantic networking is based on over thirty years of research in artificial intelligence, cognitive psychology, memetics and learning theory, and has been independently proven to be significantly more effective in the transfer of knowledge.
		Semantic networks can grow to extraordinary complexity, necessitating a sophisticated approach to knowledge visualization, balancing the need for simplicity with the full expressive power of the network.
		Semantic networks may be traversed via concept list views, via their relations, or by retracing the user's history.

	Semantic Networks (Site not responding. Last check: 2007-10-06)
		It is a node-link structure, a semantic network in which the nodes represent chapters and the links represent the relationship of which chapters should be read before which other chapters.
		Semantic networks as a representation of knowledge have been in use in artificial intelligence (AI) research in a number of different areas.
		Semantic networks are used in this project as structures of knowledge that encourage the user to interact with them.

	Associative Networks - Information Models in Graph Notation
		Although such a network may be explanatorily useful for studies of word association, it is obviously a poor instrument for semantics because a mere associative link from one word to another tells one nothing about the intensional relation between the words.
		The network is composed of links between two sorts of nodes: type nodes, which represent concepts, and token nodes, which represent instances of concepts by virtue of the links to their respective type nodes.
		Third, comprehensive network theories are based on a formalism containing three components: a parser, a semantic memory consisting of a network of links between nodes, and a set of interpretative processes that operate on the network.

	2005AC Section 3 UMLS SEMANTIC NETWORK
		The purpose of the Semantic Network is to provide a consistent categorization of all concepts represented in the UMLS Metathesaurus and to provide a set of useful relationships between these concepts.
		The Network provides information about the set of basic semantic types, or categories, which may be assigned to these concepts, and it defines the set of relationships that may hold between the semantic types.
		The Semantic Network serves as an authority for the semantic types that are assigned to concepts in the Metathesaurus.

		The network and the relationships therein are made explicit to the user of the system, thus relying upon the user's intuitive knowledge about markets.
		The value added by the system is both this semantic network structure of marketing relationships and the more intangible "feeling" of navigating and exploring an insight hyperspace.
		Semantic networks and hypertext are powerful tools for organizing and browsing marketing reports of all types, including reports produced by insight generators.

	JXTA Drives Semantic P2P Networks
		A private overlay network can also be thought of as a "semantic network," which provides a context for usage and has its own implementations of membership, security, and services that are appropriate for the type of interactions required.
		By encompassing the addressability of all devices within a semantic network, organizations can expand their networks to all who need access to them while shrinking the net to a specific mission, geographic region, echelon, and so on.
		In the semantic network approach, each of these networks, or individuals as represented by individual nodes within these networks, would have the ability to dynamically form their own ad hoc P2P networks.

	Semantic Networks
		A propositional semantic network whose nodes represent concepts and conceptual relations; type labels on the concept nodes make CGs into a typed or sorted version of existential graphs in which the EG ovals are represented by concepts of type Proposition.
		A definitional network that used a set of 56 different relation types for representing patterns used to guide a parser for disambiguating sentences in machine translation; it is one of the first semantic networks implemented on a digital computer.
		A propositional semantic network that combines relational graphs with oval nodes that may contain other EGs or RGs; when the ovals are used to negate the nested graphs, an EG can represent any proposition in first-order logic, but the ovals can also be used to represent modal and metalevel information about the nested graphs.

		The Semantic Network was created in an effort to provide a semantic framework for the UMLS and its constituent vocabularies.
		Semantic types from the Semantic Network are linked to Metathesaurus concepts by the categorization link established by the Metathesaurus editors: Each concept is categorized with at least one semantic type from the Semantic Network, independently of its hierarchical position in the source vocabularies.
		The goals are: to identify current limitations of the Semantic Network and their impact on applications and maintenance of the network itself and to analyze and discuss suggestions for changing and improving the Semantic Network.

	Ranking Semantic-linked Network
		This paper introduces the notion of semantic-linked network consisting of semantic links and semantic components, and proposes an approach for ranking the semantic-linked network, which effectively quantifies the semantic importance of semantic components.
		A semantic component is a network consisting of arcs of semantic links and small granularity semantic components.
		The network is composed of semantic components and semantic links, and a semantic component can be also a semantic-linked network.

		Quillian (1967, 1968) is generally regarded as the originator of the notion of a semantic network.
		Semantic similarity is the number of links connecting two nodes, whereas semantic distance is the length of the shortest link between two components.
		Here the semantic network is used for query expansion, and the expanded query is passed to similarity based text retrieval routines (also used by Solvberg et al, 1991/1992).

		To grasp what a semantic network is, consider two people, John and Sue, paddling in a canoe.
		Our network will include, for example (see figure 3.1), the knowledge (or assumptions) that John is a man, Sue is a woman, John is in the canoe, Sue is in the canoe, the canoe is in water, and so on.
		For example, the `isa' relationship, as typically used in semantic nets, appears to hide the important distinction between an individual object or entity (for example, `Sue') and a term specifying a class of objects or entities (for example `woman', or `human').

	Facilitation Predictions From Bower's (1981) Network Model
		The preceding explanation has been used to suggest that not only will the affective valence of stimuli influence a person's mood, but that their perception of a stimulus will be influenced by what emotion nodes are activated at a given time (i.e., their mood; Niedenthal and Setterlund, 1994).
		Traditionally, researchers subscribing to Bower's network theory have suggested that because depressed people begin a lexical decision task with activated nodes representing sadness, they begin the task with some residual activation of memory representations corresponding to negative stimuli, and not those corresponding to positive stimuli.
		Specifically, it will be suggested that the activation of a memory structure representing negativity activates multiple constructs with negative semantic content in the presence of a negative stimulus, creating interference, and thus slowing on the affective lexical decision task for negative words.

	Bootstrapping Methods for Knowledge Structuring
		Assume that we have a mental model in the form of a semantic network, which, for example, has been elicited from an individual or group of users.
		The bootstrapping techniques assume that the model is organized as a network of nodes, representing concepts and instances, connected by a variety of semantic links, representing if-then rules and IS_A hierarchies.
		For example, if two nodes A and B are identified, two nodes C and D that previously were distinguished by their links to respectively A and B will now point to the same node A-B. Therefore, C and D may themselves need to be identified, differentiated or integrated.
