Feature extraction         
In machine learning, pattern recognition, and image processing, feature extraction starts from an initial set of measured data and builds derived values (features) intended to be informative and non-redundant, facilitating the subsequent learning and generalization steps, and in some cases leading to better human interpretations. Feature extraction is related to dimensionality reduction.
Relationship extraction         
TYPE OF TEXT MINING
Relationship Extraction; Relation extraction
A relationship extraction task requires the detection and classification of semantic relationship mentions within a set of artifacts, typically from text or XML documents. The task is very similar to that of information extraction (IE), but IE additionally requires the removal of repeated relations (disambiguation) and generally refers to the extraction of many different relationships.
Terminology extraction         
AN AUTOMATIC METHOD OF ANALYSING TEXT IN ORDER TO IDENTIFY PHRASES WHICH FULFIL THE CRITERIA FOR TERMS
Term extraction; Term recognition
Terminology extraction (also known as term extraction, glossary extraction, term recognition, or terminology mining) is a subtask of information extraction. The goal of terminology extraction is to automatically extract relevant terms from a given corpus.

THE MOST BASIC UNIT OF PHONOLOGICAL STRUCTURE THAT MAY BE ANALYZED IN PHONOLOGICAL THEORY
Distinctive features; Phonological feature; Distinctive Feature theory; Phonological features; Feature (phonology); Feature theory; Feature-based phonology; Feature phonology
In linguistics, a distinctive feature is the most basic unit of phonological structure that distinguishes one sound from another within a language. For example, the feature [voice] distinguishes the two bilabial plosives: [p] and [b].
Liquid–liquid extraction         
  • 4 stage battery of mixer-settlers for counter-current extraction.
  • Phase separation during a laboratory scale LLE. The upper organic ether solution of [[MTBE]] is being extracted with the lower alkaline [[aqueous]] sodium bicarbonate solution to remove [[benzoic acid]] as the [[benzoate]] anion, leaving a non-acidic organic, [[benzil]], (yellow in color) in the organic phase.
  • Solvent extraction.
METHOD TO SEPARATE COMPOUNDS BASED ON THEIR RELATIVE SOLUBILITIES IN TWO DIFFERENT IMMISCIBLE LIQUIDS, USUALLY WATER AND AN ORGANIC SOLVENT; EXTRACTION OF A SUBSTANCE FROM ONE LIQUID INTO ANOTHER LIQUID PHASE
Solvent extraction; Solvent Extraction; Two-phase liquid extraction; Two Phase Liquid Extraction; Two phase liquid extraction; Liquid liquid extraction; Liquid-liquid extraction; Countercurrent solvent extraction
Liquid–liquid extraction (LLE), also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar). There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to organic.

ISOLATION OF DNA
DNA Extraction; Isolasi DNA; Dna extraction; DNA isolation; Extraction of DNA
The first isolation of deoxyribonucleic acid (DNA) was done in 1869 by Friedrich Miescher. Currently it is a routine procedure in molecular biology or forensic analyses.

DISTINGUISHING CHARACTERISTIC OR CAPABILITY OF SOFTWARE
Feature-rich; Feature (software design); Software enhancement; Feature (software)
In software, the term feature has several definitions. The Institute of Electrical and Electronics Engineers defines the term feature in IEEE 829 as "[a] distinguishing characteristic of a software item (e.

POSSIBILITY TO ACTIVATE AND DEACTIVATE A FUNCTION
Feature flag; Canary release
A feature toggle in software development provides an alternative to maintaining multiple feature branches in source code. A condition within the code enables or disables a feature during runtime.

In computer vision and image processing, a feature is a piece of information about the content of an image; typically about whether a certain region of the image has certain properties. Features may be specific structures in the image such as points, edges or objects.
