KEYWORDS (
BA/RRM only)
Keywords are added to a reference by BIOSIS indexers to help clarify the concepts
discussed in the original source document. Keywords can represent bibliographic
terms, organism names, geopolitical locations, industry names, drug names, and
other types of terms named in the original document.
Example:
Goat (Bovidae): neonatal kid, host; Cryptosporidium parvum
(Sporozoa): parasite
The first term in the sentence (goat) is the key term to which the rest of the sentence
corresponds. Key terms may appear alone, or may be further clarified by additional
terms which provide context, identify roles (i.e., host, parasite, animal model, etc.) and
help to show the relationship between the terms in the original document.
Terms enclosed in brackets indicate an alternate form of a key term.
Example:
PCR [polymerase chain reaction]
Terms in parentheses, present for organism and geopolitical key terms, represent the
higher taxonomic level of an organism or a broader geographic area, respectively.
Example:
Sand Dollar (Echinoidea)
Salmonella-typhimurium (Enterobacteriaceae)
And
Sao Sepe county (Brazil)
Saone (France)
The final terms which may be in a sentence (preceded by a colon), provide final clarifi-
cation of the key term. These final terms provide information about taxonomy, role,
discipline, age category, or method.
Example:
Human (Hominidae): adult
cat (Felidae): host
The remaining items in the keywords section are the major concepts discussed in the
source document. They are listed in all uppercasing.
Example:
Antiparastitc drug, antiprotozoal drug,...INFECTION; VETERINARY
MEDICINE; PARASITOLOGY.
Keywords are added by
BIOSIS indexers for clarifica-
tion to records in BA/RRM
since most records do not
contain abstracts.
