The phrase "a root term" is correct and usable in written English.
It can be used in contexts related to linguistics, mathematics, or any field where foundational concepts or elements are discussed.
Example: "In linguistics, a root term is the base form of a word from which other words can be derived."
Alternatives: "a base term" or "a fundamental term".
By the way, Newte's etymology was faulty: "organ" has nothing to do with love or any other worthy sentiment but comes from a root term for "work," giving the Greeks their words both for work (ergon) and tool (organon).
Moreover, a root term has a Resnik probability of 1, and a non-root term has a Resnik probability less than 1.
The slim designation is determined by following an annotated term to its parent terms using relationships until either a parent term is in the list of slim terms or the parent term is a root term.
Adjustment for age always included both a linear and a square root term (ageroot) in order to avoid as much as possible any residual confounding by (a function of) age.
Given that the vocabulary of death certificates is somewhat constrained, an effective term normalisation (e.g., folding synonyms to a single root term) method could be developed to deal with issues around word variations.
Duality theorems for nondifferentiable programming problem with a square root term were obtained by Lal et al. [8].
Since the textural random variable models the variance of the signal rather than its amplitude, it is introduced as a square root term in the data vector (described in [8]).
If the phenotype distribution is multivariate normal, the mean fitness is (A9) which, as in the univariate case, is reduced by a standing load (the square root term) and a lag load (the exponential).
Given a GO tree (DAG) T = (V, E), where V is the set of the nodes and E is the set of directed edges, with set of roots R⊂ V for each ontology, we define A{ i }, the set of ancestors of term i, to be the set containing all terms that are on the path from i to a root, including term i itself.
'Unknown' annotations are created by manually assigning the root term of a GO aspect, which are the broadest terms that exist: 'molecular_function' (GO 0003674), 'biological_process' (GO 0008150), and 'cellular_component' (GO 0005575).
GO has a rule called "true path rule", which defines the terms along the pathway from a given term to the root term that must annotate the protein if the protein is annotated with the given term.
