Using
corpus analysis software to analyse specialized texts
1. What
is a carpus?
In
corpus linguistics, a corpus (sometimes used in the plural form "corpora
can be generally defined as collection of naturally-occurring texts in a
camputer-readable format which can be retrieved and analyzed using corpus
analysis software'

3. Designing
a specialised corpus
Corpus size
-
There are no fixed rules; depending on
research purposes, availability of data and time.
-
Large, general corpora may be less useful
than small, focused corpora if searches are made on context-specific terms.
-
There are limitations of too small
corpora e.g. no enough hits to make decent generalization, not covering enough
concepts, terms, or patterns under investigation.
-
Is preferable to create a "monitor'
or 'open' corpus because specialized words/usage are dynamic.
Text extracts Vs. full
text
-
Depends on the aim of corpus compilation.
-
Whole text offers more coverage because
words or terms to be looked at may be randomly distributed throughout the text.
-
Specific sections may be helpful if we
are looking for words or phrases under particular content areas or want to
create purposeful sub-corpora.

Local grammar
2.1
Comparison of Adjectives
2.1.1Comparative Degree
Lesser false vampire bat smaller
than their other vampire bat cousins, the lesser false vampire bats make
their own homes in caves and hollowed out trees.
2.1.2Superlative Degree
For their size, bats are the slowest reproducing mammals
on Earth.
The tropics have the biggest variety of bat species:
Indonesia has 175 species of bats (about ten times the number of species found
in the UK). Central and South America are home to almost one third of the
world's bats species.
2.2
“Species” is used the both singular and plural.
This bat is a
member of the species Eptesicus
fuscus
(Big brown bat), which are found in the U.S.
There are more
than 950, and perhaps as many as 1,200 species of bats.
Lesser false
vampire bat, this bat species is another tent-making bat. Though it is
considered a species of "least concern" on the IUCN Red List, it is
found in forests and is somewhat at risk due to habitat loss.

Style
3.1
Present Simple Tense
Common vampire bats, Desmodus rotundus,
are warm-weather microbats from South America that live and hunt in
groups.
They are cave dwellers, and are
persecuted due to an unfounded fear of rabies: They are not major carriers of
the disease.
Bats are the only mammals capable
of true flight.
Most bats eat
flowers, small insects, fruits, nectar, pollen and leaves, though it depends on
the type of bat.
3.2
Use of passive structure
This time of
year, millions of bats from a spectrum of species are hunkered down in
caves, where they’ll huddle together for warmth and hibernate through the
winter.
This bat is a
member of the species Eptesicus fuscus (Big brown bat), which are found
in the U.S.
Many bat
species around the world are threatened with extinction.
Bats are
classified in the order Chiroptera, derived from the Greek words
"cheir" for hand and "pteron," meaning wing.

The Indiana Bat is a medium sized species. It
can range in coloring from brown, black, or gray.
Colonies of the Indian Bat will meet up with
each other for hibernation. There can be thousands and thousands of them in one
location. Typically, hibernation takes place in the state of Indiana, which
is where their name comes from.
Still other bat species feed on fish,
frogs, lizards, small rodents, small birds, and even other bats. And while
bats have an evil reputation for sucking blood.

use of Parentheses or Round
Brackets
Bats range in size across the different
species, but tend to average about 5.5 to 19 cm in length (tip to tail)
with a wingspread of approximately 15 to 38 cm. Most weigh between 3.5 and 60
grams (in the U.S
The fossil record of bats prior to the
Pleistocene Epoch (about 2,600,000 to 11,700 years ago) is limited and
reveals little about bat evolution.
The order Chiroptera is readily divided into
two suborders—Megachiroptera (large Old World fruit bats) and Microchiroptera
(small bats).
