The terms listed alphabetically in this index represent items in the
1991 version of the Computing Reviews Classification System.
The entries are composed of words and phrases that occur in: (1) the
three numbered levels of categories, (2) the subject descriptors, and
(3) the general terms. Implicit subject descriptors (or proper nouns)
are not included. The entries are listed alphabetically. Each entry is
identified by its location in the tree, or its designation as a
general term, using the legend below. The entries were created in the
following ways:
Each node name, subject descriptor, and general term is listed just as
it appears in the tree, except that items shown in the tree as
"e.g." are normally not included with their basic
entry.
Word phrases from the tree are permuted and are sequenced on each
important word in the phrase. Thus, both "Design
Languages" and "Languages, Design" (Node D.3.2) are
shown. Similarly, "Vision and Scene Understanding" (Node
I.2.10) has entries under "Scene Understanding, Vision"
and "Understanding, Vision and Scene."
Short forms, such as abbreviations or acronyms, that occur in the tree
are listed. For example, "SIMD" (a subject descriptor from
Node C.1.2) and "DDL" (a subject descriptor from Node
H.2.3) are included.
Words, phrases, or acronyms used as examples are included. Thus,
"Factoring" and "Primality testing" are
included because they are examples for the subject descriptor
"Number-theoretic computations" (Node F.2.1). Similarly,
"MIS" from the parenthetical example in Node H.4.2 is
listed.
In some cases, words or phrases from items in the tree are
deliberately omitted or combined, in order to provide a more
meaningful entry. In such cases, a dagger (°) appears after the
level symbol to indicate the modification. For example, the entry
"Languages, assembly" is a shortened form of the subject
descriptor "Macro and assembly languages" (Node D.3.2) and
the entry "Language control structures" is a combination
of the subject descriptor "Control structures" and its
higher level node (Node D.3.3, "Language Constructs and
Features").
In cases where permutations or truncations of a node or subject
descriptor would be adjacent entries, they are not included.
Each index term (except the general terms) indicates the most specific
or lowest relevant node number. For example, the subject descriptor
"Complexity Hierarchies" points to "Complexity
Classes" (Node F.1.3). The same phrases often appear in
different parts of the tree; in such cases the node name is shown in
square brackets next to the term. For example, "File
Organization [File Systems Management]" (Node D.4.3) appears
next to "File Organization [Information Storage and
Retrieval]" (Node H.3.2).
