Information pertaining to these abstraction categories was presented in the medical charts as free-text or in narrative form.
The homogeneity of kappas across chart abstraction categories was tested using the method outlined by Donner et al [ 17].
The nine data abstraction categories reflect fundamental elements of policy development, and would serve as the building blocks for policy addressing this issue.
Six chart abstraction categories were used as a basis for determining chart abstractor agreement: physical assessment, asthma control, spirometry, asthma education, referrals to specialists or education programs, and medications prescribed.
Kappa values for the chart abstraction categories were: physical assessment (κ 0.84), asthma control (κ 0.83), spirometry (κ 0.84), asthma education (κ 0.72), referral visits (κ 0.59) and medication side effects (κ 0.51).
Just as we design visuospatial discourse, we design the world: Our design actions in space create diagrams in the world, patterns, piles, rows, one-to-one correspondences, and the like, that express abstractions, categories, hierarchies, dimensions, and more, a circular process termed spraction.
This suggests that some abstraction of the category structure can occur during the testing period, in the sense that untrained controls were able to make accurate decisions without any exposure to the study items [29], but this is insufficient to account for the substantially greater number of correct decisions made by the pre-exposed participants.
Lewis (1986) defines his way of abstraction as forming categories by means of comparing a number of experienced objects and only focussing on similarities.
In contrast, the CSSN provides an abstraction network with categories such as "Organic Chemical" and "Hazardous or Poisonous Organic Chemical", which fit for mapping the ChEBI ontology to UMLS source vocabularies.
This was followed by an abstraction of the categories into more general ones (Spiggle 1994).
