Agent Assist
- Definition
- Agent assist is AI software that supports a human customer-service representative during a live contact by transcribing the conversation, surfacing answers, and drafting notes. Here the agent is the human representative.
BERT
- Definition
- BERT (Bidirectional Encoder Representations from Transformers) is a language model from Google that reads text in both directions at once and became the standard base for text classification, entity extraction, and search…
Chatbot
- Definition
- A chatbot is a software program that holds a text or voice conversation with a person to answer questions or complete simple tasks. Modern chatbots run on large language models grounded in…
Content Moderation
- Definition
- Content moderation is the review of user-generated or AI-generated content to decide whether it is allowed, using classifiers, written policies, and human reviewers for the cases a model cannot settle.
Conversational AI
- Definition
- Conversational AI is the set of technologies that lets software hold a natural, multi-turn dialogue with people by text or voice, combining speech recognition, language understanding, dialogue management, and back-end integration.
Copilot (AI Assistant)
- Definition
- A copilot is an AI assistant embedded in a work application that drafts, summarizes, and answers questions from the content the user has open, while the person keeps control of the final…
Intelligent Document Processing (IDP)
- Definition
- Intelligent document processing (IDP) combines OCR, classification, and language models to turn invoices, contracts, forms, and other documents into validated structured data that flows into business systems.
Machine Translation
- Definition
- Machine translation is the automatic conversion of text or speech from one human language to another by software, now performed by neural models that read whole sentences and follow terminology instructions.
Naive Bayes
- Definition
- Naive Bayes is a family of fast probabilistic classifiers that apply Bayes' theorem and assume every feature is independent of the others given the class, which makes them a common baseline for…
Named Entity Recognition (NER)
- Definition
- Named entity recognition (NER) is a natural language processing technique that finds and labels specific items in text, such as people, companies, dates, amounts, and identifiers, turning unstructured documents into structured fields.
Natural Language Generation (NLG)
- Definition
- Natural language generation (NLG) is the production of readable text by software from data, instructions, or other text. It is the output half of NLP and the basis of most generative AI…
Natural Language Processing (NLP)
- Definition
- Natural language processing (NLP) is the branch of AI that lets software read, interpret, and produce human language. It turns contracts, emails, call transcripts, and tickets into data a business can search,…
Natural Language Query
- Definition
- Natural language query is the ability to ask a question of a database or reporting tool in plain English and receive the answer as a table, chart, or sentence computed from live…
Natural Language Understanding (NLU)
- Definition
- Natural language understanding (NLU) is the part of NLP that works out what text or speech means, turning an open-ended sentence into an intent and extracted fields that software can act on.
Optical Character Recognition (OCR)
- Definition
- Optical character recognition (OCR) converts images of printed text, such as scans, photos, and PDFs, into machine-readable characters that software can search, extract, and process.
Recurrent Neural Network (RNN)
- Definition
- A recurrent neural network is a neural network that processes a sequence one step at a time while carrying a hidden state forward, so earlier inputs influence how later ones are interpreted.
Semantic Search
- Definition
- Semantic search is a retrieval method that finds documents by meaning rather than by matching exact words, using embeddings to return the passages closest to what the user asked.
Semantic Skills
- Definition
- Semantic skills are the capabilities that let an AI system work out what language means, including word sense, context, and intent, so it can act on requests however they are phrased.
Sentiment Analysis
- Definition
- Sentiment analysis is the use of natural language processing to determine the attitude expressed in text, usually as positive, negative, or neutral, so that customer feedback can be counted and tracked over…
Speech Recognition (ASR)
- Definition
- Speech recognition, or automatic speech recognition (ASR), is the conversion of spoken audio into written text by software, making calls, dictation, and meetings searchable and usable by other AI systems.
Summarization
- Definition
- Summarization is the use of a language model to condense a long text into a shorter one that keeps the important points, in a format and length set by the prompt.
Text Classification
- Definition
- Text classification is the task of assigning a piece of text to one or more predefined categories, such as routing a support email to billing, shipping, or returns.
Text-to-Speech (TTS)
- Definition
- Text-to-speech (TTS) is the generation of spoken audio from written text by software, used in phone systems, voice assistants, and accessibility tools to read dynamic content aloud in a natural voice.
Text-to-SQL
- Definition
- Text-to-SQL is the translation of a plain-language question into a SQL statement that a database can run, performed by a language model given the schema and business definitions.
Tokenization
- Definition
- Tokenization is the step that splits text into tokens, the word pieces a language model reads and produces, and the unit in which context windows, throughput, and usage-based pricing are measured.
Topic Modeling
- Definition
- Topic modeling is an unsupervised learning technique that discovers the themes running through a large collection of documents without being told in advance which categories to look for.
Virtual Assistant
- Definition
- A virtual assistant is a conversational AI application that helps a person complete tasks across several systems on request, such as booking a room, checking a balance, or updating a ticket.
Web Scraping
- Definition
- Web scraping is the automated extraction of data from websites by software, and a web crawler discovers pages by following links. Both feed pricing, research, and AI training data pipelines.
