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.
Semantic Textual Similarity
Semantic Textual Similarity (STS) is the natural language processing task of scoring how semantically equivalent two sentences are, on a scale from 0 to 5.
Semantic UI
Semantic UI is an open-source front-end development framework created by Jack Lukic and released in 2013, providing pre-built user interface components through human-friendly, descriptive HTML class names and variable-driven theming.
Semantic versioning
Semantic versioning, or SemVer, is a software versioning convention codified in specification 2.0.0 by Tom Preston-Werner, where MAJOR.MINOR.PATCH numbers signal incompatible API changes, new features, and bug fixes.
Semantic Web
The Semantic Web, also known as the Data Web, is a W3C vision of the Web where data carries explicit machine-readable meaning, built on standards like RDF, SPARQL, and OWL.
Semantic Web Rule Language
The Semantic Web Rule Language (SWRL) is a rule language for the Semantic Web that combines OWL DL and OWL Lite with Horn-like rules, proposed in a 2004 W3C submission.
SemanticKITTI
SemanticKITTI is a large-scale dataset for LiDAR-based semantic scene understanding, providing dense point-wise annotations for every KITTI Odometry sequence over the full 360° field of view.
Semaphore
A semaphore is an optical telegraph relaying coded messages between staffed stations, invented by the Chappe brothers in France; the first Paris-to-Lille line opened in 1794.
Semaphore (programming)
A semaphore is a programming synchronization primitive, a counter with atomic wait and signal operations introduced by Edsger Dijkstra in 1965 to control access to shared resources between threads.
SEMATECH
SEMATECH, short for Semiconductor Manufacturing Technology, is an American not-for-profit research consortium founded in Austin, Texas, in 1987, jointly funded by the Defense Department and member companies until 1996.
Sembcorp Industries
Sembcorp Industries is a Singapore-headquartered energy and urban solutions company, formed in 1998 from a merger, operating 28.5GW of renewables and gas capacity across 11 countries.
SemEval
SemEval (International Workshop on Semantic Evaluation) is a natural language processing workshop series, begun in 1998 as SENSEVAL for word sense disambiguation, where teams compete on shared evaluation tasks.
SEMI
SEMI, originally Semiconductor Equipment and Materials International, is a global semiconductor industry association founded in 1970, known for its SEMICON expositions and more than 1,000 technical standards.
Semi-acoustic guitar
The semi-acoustic guitar, also called a semi-hollow or hollow body electric guitar, is an electric guitar with a solid wood center block inside a partly hollow body.
Semi-active suspension
Semi-active suspension is a vehicle suspension in which an electronic controller continuously adjusts the shock absorbers' damping to road conditions and load, improving comfort while consuming little power.
Semi-automatic firearm
A semi-automatic firearm, also called a semi-automatic gun, is a gun that reloads itself automatically after each shot but fires only one round with each pull of the trigger.
Semi-Automatic Ground Environment
The Semi-Automatic Ground Environment (SAGE) was a US continental air defense system in which radars fed track data to AN/FSQ-7 computers that directed interceptors, fully deployed in 1963.
Semi-automatic pistol
A semi-automatic pistol, also called a self-loading pistol, is a magazine-fed handgun firing one cartridge per trigger pull, distinguished from revolvers and fully automatic pistols.
Semi-automatic rifle
A semi-automatic rifle is a rifle that fires one shot per trigger pull, automatically chambering the next round; the first was built in 1885 by Ferdinand von Mannlicher.
Semi-automatic switchboard
A semi-automatic switchboard, also called a dial-system or semi-mechanical exchange, was telephone switching in which an operator keyed the wanted number and automatic machinery set up the connection.
Semi-automatic transmission
A semi-automatic transmission, also called a clutchless manual or paddle-shift gearbox, is a car transmission where the driver picks gears while actuators work the clutch.
Semi-autonomous teleoperation
Semi-autonomous teleoperation, also known as shared control, is a mode of robot teleoperation where robot autonomy handles obstacle avoidance and local perception while the human operator retains high-level decision-making and mission planning.
Semi-blind channel estimation
Semi-blind channel estimation estimates wireless channels by combining a few known pilot symbols with blind information from the data itself, resolving the ambiguities of fully blind methods while saving bandwidth.
Semi-detached
A semi-detached house, also called a twin house, is a dwelling sharing one common wall with a single neighboring house, the pair forming a block of two.
Semi-solid flow battery
A semi-solid flow battery (SSFB) is a flow battery that stores energy as particles suspended in a liquid electrolyte, first demonstrated at MIT in 2011.
Semi-solid metal casting
Semi-solid metal casting, also called thixoforming, is a metal forming process that shapes alloy as a slurry between solid and liquid, pioneered at MIT in 1971.
Semi-submersible platform
A semi-submersible platform is a floating offshore structure whose submerged pontoons and widely spaced columns give low motions and high stability for deepwater drilling and production.
