termopaare

Termopaare is a concept used in linguistics and information retrieval to refer to a pair of terms that are related in meaning, usage, or co-occurrence within a text corpus. It serves as a basic unit for studying semantic relationships, extracting knowledge from text, and supporting tasks such as query expansion, topic modeling, and knowledge-base construction.

Termopaare can be derived from raw text by identifying co-occurring terms within a defined window, or by analyzing syntactic relationships using dependency parsing. Statistical measures such as pointwise mutual information, Dice coefficient, Jaccard similarity, or likelihood ratios are commonly used to score termopaare and distinguish meaningful associations from random co-occurrence.

Applications include building thesauri, enhancing search relevance, detecting collocations, and enriching graphs in knowledge bases. Example: in a finance corpus, the termopaare ('stock', 'price') or ('risk', 'portfolio') frequently appear together.

Terminology: Termopaare is sometimes treated as synonymous with term pairs or collocational pairs; in many contexts it overlaps with bigrams and co-occurrence pairs. Related concepts include collocation, bigram, co-occurrence, and semantic similarity.
