Word2vec
Word2vec is a family of neural network methods introduced by Tomas Mikolov and colleagues at Google in 2013 that learns word embeddings from large amounts of plain text.
WordNet
WordNet is a large lexical database of English, begun in the mid-1980s at Princeton University under George A. Miller, grouping words into synonym sets called synsets.
WordPiece
WordPiece is a subword tokenization algorithm that splits words into pieces marked with a ## prefix, introduced at Google in 2012 and best known as the tokenizer of BERT.
Work stealing
Work stealing is a load-balancing scheduling strategy for parallel computing in which idle processors take queued tasks from busy processors, reducing overhead compared with work sharing.
Workato
Workato is a US enterprise automation and iPaaS company founded in 2013 by Vijay Tella and others, known for its recipe-based workflows, repeated Gartner Magic Quadrant Leader placements, $415M funding, and Enterprise MCP for AI agents.
Workflow orchestration
Workflow orchestration coordinates automated tasks across systems using DAGs, schedules, triggers, retries, and state tracking; distinct from automation, ETL, and process orchestration; tools include Airflow, Temporal, Argo, and Step Functions.

The World Artificial Intelligence Conference (世界人工智能大会), or WAIC, is an annual government-backed AI conference and exhibition in Shanghai since 2018, known for global AI governance talks.
World-Check
World-Check is a commercial risk-intelligence database used by banks, governments, and police for sanctions screening, PEP monitoring, and anti-money-laundering checks. Founded in 2000, it now belongs to London Stock Exchange Group.
WorldCat
WorldCat, also known as OCLC WorldCat or WorldCat.org, is the union catalog of OCLC, merging catalog records from more than 10,000 libraries worldwide since 1971 for interlibrary loan and discovery.

Write-ahead logging
Write-ahead logging (WAL) is a database technique that records changes in a durable log flushed to disk before the modified data pages are written, enabling crash recovery.
Wumpus World
Wumpus World: classic AI grid-world cave (4x4) from Genesereth and Russell & Norvig's AIMA; an agent uses percepts (stench, breeze, glitter, bump, scream) to find gold, avoid pits and the wumpus, and escape.
X-means
X-means is a clustering algorithm that extends K-means by automatically estimating the number of clusters. It was introduced by Dan Pelleg and Andrew Moore at ICML 2000.
x-vector
An x-vector is a fixed-dimensional speaker embedding produced by a deep neural network, introduced by Snyder and colleagues at ICASSP 2018; it replaced i-vectors as the dominant speaker recognition approach.
Xception
Xception is a convolutional neural network architecture for image classification, reported by François Chollet in 2016, built on depthwise separable convolutions and widely used as a pretrained backbone.
XGBoost
XGBoost, short for eXtreme Gradient Boosting, is a gradient-boosted decision tree library introduced by Tianqi Chen and Carlos Guestrin in 2016 and widely used in machine learning competitions.

XLA (Accelerated Linear Algebra) is a machine learning compiler that optimizes linear algebra computations for speed and memory, compiling models from TensorFlow, JAX, and PyTorch for CPUs, GPUs, and TPUs.
XML Encryption
XML Encryption is a W3C standard for encrypting arbitrary data, an XML element, or element content and representing the result in XML; it became a Recommendation in 2002.
XML for Analysis
XML for Analysis (XMLA) is a SOAP-based open protocol published by Microsoft and Hyperion in 2001 for querying OLAP and data mining servers over HTTP, using two methods, Discover and Execute, carrying MDX queries; version 1.1 came in 2002.
XNLI
XNLI, or Cross-lingual Natural Language Inference, is an evaluation dataset created by Facebook AI and New York University in 2018, covering natural language inference in 15 languages.
XOR gate
The XOR gate, or exclusive-OR gate, is a digital logic gate whose output is 1 exactly when its two inputs differ, written A ⊕ B.
XPath
XPath (XML Path Language) is a W3C expression language for addressing parts of an XML document through path expressions, and it serves as the expression language at the core of XSLT and XQuery.
XQuery
XQuery is a functional query and application development language, standardized by the W3C, for extracting and restructuring information from XML documents and, since 3.1, JSON.
