Morphosemantic Analysis of -ITIS Forms in Medical Language

Abstract

This paper describes an automated procedure for morphosemantic analysis and semantic interpretation of medical compound word forms ending in -ITIS. The requirements for morphosemantic analysis of -ITIS forms include : a) semantic classification of morphosemantic constituents forming -ITIS word forms, b) establishment of morphosemantic distribution patterns occurring in -ITIS forms, c) preparation of paraphrasing rules.

Natural Language Processing in Medicine: An Overview

“…[138,139]. The underlying syntactic-semantic composition rules are described so that automated meaning analysis and paraphrasis can be done [140,141]. This is useful for dictionary building and textindexing.…”

MorphoSaurus

“…Metathesaurus for semantic indexing [24]. Follow-up studiesbyPacak andNorton [25,26] not onlydetermine apreferred normalizedf ormf or severalm orphologicalv ariants butr atherc omputep araphrase and other sortsofs emantic (e.g., locative, causative) relations.These relations arei mplicitlyd enoted by complexn ominalc ompounds (also common in Englishm edical jargon [4]) andc an be made explicitb y breaking compounds up into their constituent (morpho-semantic) parts. Pacak et al, however, arenot at allconcernedwith interlingualaspects of thesemorphologicalunits andtheir organization in semantic equivalence classes.A nother limitation of their work is due to restricting the decomposition of compounds to those denoting inflammatoryprocesses (indicated by the '-itis'ending) or to surgical procedures(as indicated, e.g., by the '-ectomy 'or' -plasty'ending).…”

Advances in Natural Language Processing

“…-ganglion lymphatique abdominal (abdominal lymph node): ganglion (node) contains lymphe (lymph) located-in abdomen -vésicule cutanée acantholytique (acantholytic blister ): (vésicule located-in peau) (blister ) caused-by acantholyse (acantholysis) Such analysis of medical terms can be qualified through the semantic axes of their primitives, for instance those from SNOMED, as it has been done with compound terms [39]. Term ganglion lymphatique abdominal (abdominal lymph node) can thus be described as the combination of axes M (morphology or illness) and T (topology or body parts): ganglion (node) from axis M , lymphe (lymph) from axis T , and abdomen abdomen from axis T .…”
