Sentiment analysis is a natural language processing technique that determines the emotional tone or attitude expressed in a piece of text, such as classifying a review as positive, negative, or neutral.

What Is Data Cleansing?
Data cleansing (or data cleaning) is the process of detecting and correcting or removing inaccurate, incomplete, or duplicate records within a dataset to improve its quality and reliability.
What Is Alternative Data?
Alternative data refers to non-traditional data sources, such as web-scraped pricing, satellite imagery, or transaction records, used to gain insights that conventional data sources don’t provide, especially in finance and market research.
What Is LLM-Ready Data?
LLM-ready data refers to web or document content that has been cleaned and structured (often into formats like Markdown or JSON) specifically so it can be directly ingested by a large language model or RAG pipeline.
What Is Reinforcement Learning from Human Feedback (RLHF)?
Reinforcement Learning from Human Feedback (RLHF) is a machine learning technique that fine-tunes a model’s behavior using a reward signal derived from human preference judgments, rather than a fixed labeled dataset alone.
What Is Named Entity Recognition (NER)?
Named Entity Recognition (NER) is a natural language processing task that identifies and classifies named entities in text, such as people, organizations, locations, and dates.
What Is Knowledge Graph?
A knowledge graph is a structured representation of knowledge as a network of entities and the relationships between them, allowing complex, interconnected data to be queried and reasoned over.
What Is Vector Database?
A vector database is a database designed to store and query high-dimensional vector embeddings, enabling fast similarity search based on meaning rather than exact keyword matches.
What Is Model Context Protocol (MCP)?
Model Context Protocol (MCP) is an open standard for connecting AI systems, such as language models, to external tools and data sources in a consistent, interoperable way.
What Is Retrieval-Augmented Generation (RAG)?
Retrieval-Augmented Generation (RAG) is a technique that lets a large language model retrieve relevant external data at the time of a query, rather than relying only on knowledge learned during training.
What Is Synthetic Data?
Synthetic data is artificially generated data that mimics the statistical properties of real-world data, used to train or test machine learning models when real data is scarce, sensitive, or imbalanced.
What Is Data Annotation?
Data annotation is the process of labeling raw data — text, images, audio, or video — with tags or metadata so that machine learning models can learn to interpret it correctly.
What Is AI Training Data?
AI training data is the dataset used to teach a machine learning model to recognize patterns and make predictions, typically consisting of labeled or structured examples relevant to the task at hand.
What Is Data Pipeline?
A data pipeline is a series of automated steps that move data from one or more sources through processing stages to a final destination, such as a database, dashboard, or another application.
What Is ETL (Extract, Transform, Load)?
ETL (Extract, Transform, Load) is a three-step data integration process that pulls data from a source, converts it into a usable format, and loads it into a destination system such as a database or data warehouse.
What Is Web Scraping API?
A web scraping API is a service that handles the technical complexity of scraping — proxies, browser rendering, and anti-bot evasion — and returns clean, structured data from a given URL through a simple API call.
What Is JSON?
JSON (JavaScript Object Notation) is a lightweight, text-based data-interchange format that represents structured data as key-value pairs, widely used for transmitting data between servers and applications.
What Is Webhook?
A webhook is an automated HTTP callback that delivers data to a specified URL in real time when a particular event occurs, rather than requiring the receiver to repeatedly request updates.
What Is API Endpoint?
An API endpoint is a specific URL where an API can be accessed to retrieve or send data for a particular resource or function.
What Is REST API?
A REST API is a web API that follows the constraints of Representational State Transfer (REST), an architectural style that uses standard HTTP methods to access and manipulate resources.
