Что (кто) такое selective extraction - определение

TYPE OF TEXT MINING
Relationship Extraction; Relation extraction

Relationship 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.
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.
