Semaglutide
Semaglutide (Ozempic, Wegovy, Rybelsus) is a Novo Nordisk GLP-1 receptor agonist approved since 2017 for type 2 diabetes, obesity, cardiovascular risk reduction, and chronic kidney disease, with oral and injectable forms.
Semai
Semai (also spelled semaî) is a verse form of Turkish âşık folk poetry, sung softly with the saz in an 8-syllable meter on love and separation.
Semaineh
Semaineh, also spelled Semaina, is a Predynastic cemetery and settlement site in the Hu region of Upper Egypt near Nag Hammadi, excavated by Flinders Petrie in 1898–1899.
Semaj Morgan
Semaj Morgan (born 2005) is a college football wide receiver and punt returner from Detroit, Michigan, who played at Michigan (2023-2025, 2023 national title) before transferring to UCLA.
Semakovskoye Gas Field
The Semakovskoye Gas Field (Семаковское) is a large natural gas field in northern Russia with over 320 billion m³ of reserves, produced from shore through extended-reach wells since 2022.
Semantic caching
Semantic caching is a caching technique for large language model applications: prompts are compared as embeddings, and similar queries receive a cached response, cutting cost and latency.
Semantic change
Semantic change (semantic shift, lexical semantic change) is the historical-linguistics study of how word meanings shift over time, with standard types broadening, narrowing, amelioration, pejoration, metaphor, and metonymy, and a growing computational research field.
Semantic classification task
The semantic classification task, or semantic categorization task, is a reaction-time paradigm in which participants judge whether a word or picture belongs to a semantic category.
Semantic clustering
Semantic clustering is a text-mining method that groups words, sentences, or documents by meaning, converting each into an embedding vector and clustering items whose vectors are close, unlike word-count-based methods.
Semantic decision task
A semantic decision task is an experimental paradigm in which people judge whether a word or picture fits a category, used to study semantic memory.
Semantic dementia
Semantic dementia, or semantic variant primary progressive aphasia (svPPA), is a frontotemporal dementia causing loss of word and object meaning from left-predominant anterior temporal lobe atrophy, with TDP-43 type C pathology and spared fluency.
Semantic differential
The semantic differential is a psychometric rating method in which respondents judge concepts on bipolar adjective scales such as good–bad, introduced by Osgood, Suci, and Tannenbaum in 1957.
Semantic entropy
Semantic entropy is an uncertainty measure for large language model output, computed over the meanings of sampled answers rather than their exact wording, proposed in 2023.
Semantic Error (시맨틱 에러)
Semantic Error (시맨틱 에러) is a Korean BL campus romance by Jeo Soo-ri, adapted into a webtoon, anime, 2022 Watcha drama starring Park Seo-ham and Park Jae-chan, and a 2022 film.
Semantic feature analysis
Semantic feature analysis is a naming therapy for aphasia in which a person generates semantic features of a target word, improving retrieval of trained words.
Semantic fluency task
The semantic fluency task is a neuropsychological test in which a person names as many items as possible from a category, usually animals, in one minute.
Semantic Interpretation for Speech Recognition
Semantic Interpretation for Speech Recognition (SISR) 1.0 is a W3C Recommendation (5 April 2007) defining tags in SRGS speech grammars, in ECMAScript script or string-literal form, to compute machine-readable meaning from recognized utterances.
Semantic Kernel
Semantic Kernel is Microsoft's open-source, model-agnostic SDK for building and deploying AI agents and multi-agent systems on large language models, released in 2023 and succeeded by Microsoft Agent Framework.
Semantic layer
Semantic layer, also called metrics layer or business layer: a governed abstraction between raw data and BI tools, AI models, and agents defining metrics, dimensions, and relationships once; traces to the BusinessObjects Universe of 1990; the Open Semantic Interchange specification (now Apache Ossie, incubating) was published in 2026.
Semantic memory
Semantic memory: Tulving's 1972 memory system for general world knowledge, facts, and word meanings, distinct from episodic memory; hub-and-spoke ATL brain basis, K.C. and semantic dementia evidence.
Semantic network
A semantic network, also known as a semantic net, is a knowledge representation in which concepts are graph nodes and semantic relations are labeled edges.
Semantic network analysis
Semantic network analysis is a social science method that maps words or concepts from texts as network nodes linked by relations such as co-occurrence, revealing themes in discourse.
Semantic paradoxes
Semantic paradoxes are paradoxes arising from semantic notions like truth, reference, and definability through self-reference, the best known being the Liar paradox, studied since Eubulides in the 4th century BC.
Semantic parsing
Semantic parsing is the natural language processing task of translating utterances into machine-readable meaning representations, so users can query databases without a formal query language.
Semantic role labeling
Semantic role labeling (SRL) is a natural language processing method that identifies verbs in a sentence and assigns roles such as agent or patient to their arguments.
Semantic satiation
Semantic satiation, also known as verbal satiation, is a psychological phenomenon where rapid repetition of a word causes it to seem to lose its meaning.
Semantic Scholar
Semantic Scholar is a free, AI-powered search engine for scientific literature developed by the Allen Institute for Artificial Intelligence, launched in 2015 and now indexing over 200 million papers.
Semantic segmentation
Semantic segmentation is a computer vision task that assigns a semantic class to every pixel of an image, used in medical imaging, autonomous vehicles, and remote sensing.
Semantic similarity
Semantic similarity is a measure of how closely two linguistic items, such as words, sentences, or documents, match in meaning, and is central to natural language processing.
Semantic SLAM
Semantic SLAM, or semantic simultaneous localization and mapping, lets a robot build a map while attaching object identities and place concepts, supporting tasks beyond geometric navigation.
