Knowledge Graph
In knowledge representation and reasoning, a knowledge graph is a knowledge base that uses a Graph (discrete mathematics), graph-structured data model or topology to represent and operate on data. Knowledge graphs are often used to store interlinked descriptions of Named entity, entities objects, events, situations or abstract concepts while also encoding the free-form semantics or relationships underlying these entities. Since the development of the Semantic Web, knowledge graphs have often been associated with linked data, linked open data projects, focusing on the connections between concepts and entities. They are also historically associated with and used by search engines such as Google Knowledge Graph, Google, Bing (search engine), Bing, Yext and Yahoo; Knowledge Engine (Wikimedia Foundation), knowledge-engines and question-answering services such as WolframAlpha, Apple's Siri, and Amazon Amazon Alexa, Alexa; and social networks such as LinkedIn and Facebook.

Semantic Network
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, mapping or connecting semantic fields. A semantic network may be instantiated as, for example, a graph database or a concept map. Typical standardized semantic networks are expressed as semantic triples. Semantic networks are used in natural language processing applications such as semantic parsing and word-sense disambiguation. Semantic networks can also be used as a method to analyze large texts and identify the main themes and topics (e.g., of social media posts), to reveal biases (e.g., in news coverage), or even to map an entire research field.

Knowledge Engine (Wikimedia Foundation)
Knowledge Engine (KE) was a search engine project initiated in 2015 by the Wikimedia Foundation (WMF) to locate and display verifiable and trustworthy information from public-information sources in a way that was less reliant on traditional search engines. It aimed to allow readers to stay on Wikipedia.org and other Wikipedia-related projects when looking for additional information rather than turning to proprietary search engines. Its goal was to protect user privacy, to be open and transparent about how its information originates, and to allow access to related metadata. The project was controversial internally, and ended early in 2016. Related ideas were applied to the internal cross-wiki search engine for Wikimedia projects. History In 2015, WMF applied for a $250,000 grant from the Knight Foundation to support development of the Knowledge Engine. Its grant proposal noted: "Commercial search engines dominate search-engine use of the Internet, and they're employing propriet ...

Wordnet
WordNet is a lexical database of semantic relations between words that links words into semantic relations including synonyms, hyponyms, and meronyms. The synonyms are grouped into ''synsets'' with short definitions and usage examples. It can thus be seen as a combination and extension of a dictionary and thesaurus. Its primary use is in automatic natural language processing, text analysis and artificial intelligence applications. It was first created in the English language and the English WordNet database and software tools have been released under a BSD License, BSD style license and are freely available for download. The latest official release from Princeton was released in 2011. Princeton currently has no plans to release any new versions due to staffing and funding issues. New versions are still being released annually through the Open English WordNet website. Until about 2024 an online version was previously available through wordnet.princeton.edu. That version of WordNet h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graph Algebra
In mathematics, especially in the fields of universal algebra and graph theory, a graph algebra is a way of giving a directed graph an algebraic structure. It was introduced by McNulty and Shallon, and has seen many uses in the field of universal algebra since then. Definition Let be a directed graph, and an element not in . The graph algebra associated with has underlying set V \cup \, and is equipped with a multiplication defined by the rules * if x,y \in V and (x,y) \in E, * if x,y \in V \cup \ and (x,y)\notin E. Applications This notion has made it possible to use the methods of graph theory in universal algebra and several other areas of discrete mathematics and computer science. Graph algebras have been used, for example, in constructions concerning dualities, equational theories, flatness, groupoid rings, topologies, varieties, finite-state machines, tree languages and tree automata, etc. See also * Group algebra (other) * Incidence algebra ...

Edgar W
Edgar is a commonly used masculine English given name, from an Anglo-Saxon name ''Edgar'' (composed of '' ead'' "rich, prosperous" and '' gar'' "spear"). Like most Anglo-Saxon names, it fell out of use by the Late Middle Ages; it was, however, revived in the 18th century, and was popularised by its use for a character in Sir Walter Scott's ''The Bride of Lammermoor'' (1819). The name was more common in the United States than elsewhere in the Anglosphere during the 19th century. It has been a particularly fashionable name in Latin American countries since the 20th century. People with the given name * Edgar the Peaceful (942–975), king of England * Edgar the Ætheling (c. 1051 – c. 1126), last member of the Anglo-Saxon royal house of England * Edgar of Scotland (1074–1107), king of Scotland * Edgar Alaffita (born 1996), Mexican footballer * Edgar Allan (other), multiple people * Edgar Allen (other), multiple people * Edgar Angara (1934–2018), Fil ...

Linguistics
Linguistics is the scientific study of language. The areas of linguistic analysis are syntax (rules governing the structure of sentences), semantics (meaning), Morphology (linguistics), morphology (structure of words), phonetics (speech sounds and equivalent gestures in sign languages), phonology (the abstract sound system of a particular language, and analogous systems of sign languages), and pragmatics (how the context of use contributes to meaning). Subdisciplines such as biolinguistics (the study of the biological variables and evolution of language) and psycholinguistics (the study of psychological factors in human language) bridge many of these divisions. Linguistics encompasses Outline of linguistics, many branches and subfields that span both theoretical and practical applications. Theoretical linguistics is concerned with understanding the universal grammar, universal and Philosophy of language#Nature of language, fundamental nature of language and developing a general ...

Social Network
A social network is a social structure consisting of a set of social actors (such as individuals or organizations), networks of Dyad (sociology), dyadic ties, and other Social relation, social interactions between actors. The social network perspective provides a set of methods for analyzing the structure of whole social entities along with a variety of theories explaining the patterns observed in these structures. The study of these structures uses social network analysis to identify local and global patterns, locate influential entities, and examine dynamics of networks. For instance, social network analysis has been used in studying the spread of misinformation on social media platforms or analyzing the influence of key figures in social networks. Social networks and the analysis of them is an inherently Interdisciplinarity, interdisciplinary academic field which emerged from social psychology, sociology, statistics, and graph theory.
