2 LITERATURE REVIEW
Some elements that might be the focus of a corpus
study are words or phrases. The frequency of a word
in the textbook and corpus can be studied to see
whether the words are commonly used. It might also
be used to find the words that become the main
features in a register. Counting the word frequency
in a specific register also gives pictures which words
are important to be learnt by the students.
Some words tend to co-occur with other words.
Such kinds of words are called collocations.
Collocations of the words tend to be investigated
especially the ones in learners’ writing and corpus.
The use of appropriate collocations makes learners’
writing sounds natural. For instance, to describe
applying research, word research can be used with
conduct. It forms the collocation conduct research.
Words that become the members of collocations
might occur in sequence or another element might
occur between them. The span is four or five words
to the left or right. Sometimes, the learners do the
translation when dealing with collocations. They
translated the phrases word by word in their mother
tongue into the target language. It might result in
unnatural language.
Investigating collocations might reveal the
characteristics of language function in conversation.
Studying collocations of disagreeing shows that the
speakers tend to have respected and give reasons in
giving disagreement (Mutiara, 2017). These two
functions are related to maintaining the
relationshipbetween the speakers and the
interlocutors. This finding can be accommodated
when developing the syllabus and learning materials.
By doing so, the learners are exposed to the nature
of disagreement in real life. They become to realize
that language is not only structures but also social
functions.
Phrases are also investigated in the corpus. Some
phrases are formed by definite words,and it was
realized as a unit. According to Gläser (1998), it is
“a phraseological unit is a lexicalized, reproducible
bilexemic or polylexemic word group in common
use, which has relative syntactic and semantic
stability.” Therefore, such phrases have forms like a
sentence that carry language functions. They have
essential roles in texts (Biber and Conrad, 1999).
They can consist of three, four, or five words. For
example, do you agree with me is a phrase consists
of 5 words and I strongly disagree is a phrase that
consists of 3 words.
Those phrases occur in the textbooks as language
models. They are labeled as expressions, for
instance, expressions of giving agreement,
requesting, asking opinions, etc. Expressions in the
textbook can be compared and contrasted to the ones
from the corpora. Sznajder (2010) studied words
and phrases that carry metaphoric meanings. It was
found that almost a third of the words and phrases in
the textbook do not occur in the corpus. In another
case, Seto (2009) examined expressions of
agreement in 5 textbooks and corpus. He focused on
similarities and differences among them. Out of 54
expressions, there is 7 percent of expressions that
can be found in the corpus. Furthermore, the
expressions in the textbook tend to appear as a long
phrase while the ones in the corpus are in the forms
of one-word expressions.
For comparing and contrasting language
elements, the corpus must be selected carefully.
Some corpora cover both spoken and written
languages while the others only include one of them.
For the corpus study, the similar characteristic of the
language in the textbook and corpus is necessary.
For instance, when studying phrases in the spoken
language, the language in the corpus is the spoken
language. Thus, a balanced comparison can be
established. This study focuses on phrases that are
used to ask opinions in spoken language.
Asking opinions is one of the expressions in the
textbook. In interaction, asking opinions is a way to
give an opportunity for the interlocutors to speak up
their mind. Two ways interactions are developed in
such a way. In a conversation, they give equal
position both for the listeners and speakers in the
dialogues. To accommodate this issue, it is
necessary to examine the characteristics of dialogues
in which asking opinions occur. It deals with what
other language functions that the speakers produce
when they ask opinions. Having information about it
will be an advantage for developing the learning
materials. Dialogues constructed in the textbook will
have the same characteristics as the ones in the
corpus. Besides, finding other possible expressions
of asking opinions is necessary to provide more
various expressions to enrich language input for the
learners.
Based on the discussion above, the study sought
to answer some questions as can be seen below. Do
expressions of asking opinions in the textbook occur
in the corpora? How are the positions of the
expressions in the textbook compared to the ones in
the corpora? How are the characteristics of the
dialogues in which the expressions of asking
opinions occur? What are possible expressions to
ask opinions based on the findings in the corpora?
