expressionssuch

expressionssuch is a term that has appeared in some discussions of language technology and data mining, but it is not a widely standardized concept. In its tentative use, expressionssuch denotes the task of locating, identifying, and extracting expression-level patterns from text data. The term is often described as a neo-lexeme or gloss used in exploratory or proposal-driven writing rather than as an established scholarly category.

Etymology and usage notes suggest a blend of the word expression with the English or German word for “search” (such), implying a focus on searching for linguistic expressions. Because it is not codified in major references, its exact scope can vary between contexts, from practical search queries to theoretical discussions of how expressions are represented in corpora or knowledge bases.

Concept and scope: expressionssuch generally concerns expression-level phenomena such as multiword expressions, idioms, collocations, and recurring syntactic frames. It can refer to both the discovery of such expressions in large datasets and the design of search or extraction methods aimed at retrieving them. In some usages, it also encompasses template-like or semi-structured linguistic patterns that recur across texts.

Applications and methods: potential applications include corpus linguistics, information retrieval, lexicography, and natural language processing. Methods may combine rule-based pattern matching, statistical association measures, machine learning for pattern recognition, and traditional search tools or regular expressions to identify target expressions.

Status: due to its informal status, expressionssuch may overlap with established concepts such as pattern mining, phrase extraction, or multiword expression identification. It remains a niche or preliminary term rather than a standard category.
