Combining intuition with corpus linguistic analysis: A study
Combining intuition with corpus linguistic analysis: A study of lexical chunks in four Chinese undergraduate students writing Maria Leedham [email protected] FLaRN 2010 BACKGROUND TO STUDY 2 FLaRN 2010 Maria Leedham Chunking through intuition: Study 1 RQ: To what extent can NSs and NNSs chunk NNS speech? Data: transcripts of 2 intermediate-level Japanese students speech students were recorded 3 times with a 2-month gap between each total of approx.1500 words across the 6 transcripts Method Step 1: 3 NS linguists asked to underline chunks in the 6 transcripts (training, examples and practice given first) Step 2: Japanese students asked to identify chunks in their own transcripts Step 3: author chunks transcripts with assistance from WordSmith Tools (Leedham, 2006) FLaRN 2010 Maria Leedham
Example of chunked transcript from Study 1 Key: italics - words classified by the NNS as a chunk. underline words 2 or 3 out of the 3 NSs classified as a chunk 1 ahhfirst err I, I learned, learnt? (mmhmm I learnt) err (2.0) I should err.. I 2 should be more positive? (right) positive in UK because ahhwhen, when I 3 went to London err last Sunday (mhmm) ahh (2.0) some, some of the 4 underground line (mm) line was no service (oh dear) ((speaker laughs)) I was 5 really surprised and, because it can, cannot be (mm) in Japan (mm) you know, 6 sun- in, in Sunday, on? (mm) on Sunday many, many people (mm) come to 7 London (mm) and go around some place (mm)... so everyone need to, need a 8 train (mm) so, but maybe four or five lines was not, no service (mm) so 9 I I have to think err what I should do ((speaker laughs)) and no, Ive never, I 10have never been to London that, so, this was the first time Ive been to London 11(mm) so FLaRN 2010 Maria Leedham Findings from Study 1 Findings: little inter or intra-rater reliabilitiy
many missing chunks (eg of course, you know) both across and within raters frustrating and time-consuming task for NSs BUT the Japanese ss could do this task AND also offered insights into when/why (eg student M: I used to say that but now I know its not usual.) the more time spent looking for chunks, the more will be found Coda a further recording, transcribing & awareness-raising cycle suggests that this resulted in uptake both students found it highly motivating to record and analyse transcripts of their talk FLaRN 2010 Maria Leedham Chunking through intuition: Study 1 Method Step 1: 3 NS linguists asked to underline chunks in the 6 transcripts (training, examples and practice given first) Step 2: Japanese students asked to identify chunks in their own transcripts Step 3: author chunks transcripts with assistance from WordSmith Tools v.5 FLaRN 2010 Maria Leedham STUDY 2: FLaRN 2010 Maria Leedham

texts, the discipline, all Chinese students writing, all English students writing. Method 2: Key n-gram searches Used WordSmith Tools, v.5 (Scott, 2008) Searched for key n-grams in the corpus of texts from each student, using relevant discipline corpus from L1 English as reference Setting p=0.00001, deleted short ngrams within longer n-grams Compiled key n-gram lists Looked at concordance lines and texts for more context FLaRN 2010 Maria Leedham Formulaic sequences in sample of Weis writing (Engineering) Introduction A design methodology for a gearbox is presented in this report. The input horse power, the input speed and net reductions in the gearbox are the parameters to be specified. A gearbox takes an input shaft rotating and converts it via a gear train into up to three outputs, the process of designing a gearbox is to figure out which ratios are needed and to implement those
ratios in the form of positioning various sizes of connected gears. The specification of the gearbox depends on its area of application. In this report, a gearbox is designed for a commercial meat slicer which has its final shaft rotating at between 80 and 100 rev/min. The input of the meat slicer is a constant speed AC motor running at 1800 rev/min and delivering 1.2 kW. A few points have to be considered on this system, the size of the gearbox is severe restricted, since it has to go onto a work surface where there is severe competition for space. And the motor may be in-line or at right angles to the grinder. Furthermore, the duty is expected to be up to 6 hours per day. FLaRN 2010 Maria Leedham Outline 1. Research questions 2.

Single chunks are missed Arbitrary parameters Conflation of writing from lots of individuals Sense of text as complete document is lost FLaRN 2010 Maria Leedham 30 of 10 Combining methods Combine the two methods through a recursive process of reading texts and checking the sequences in a corpus, also searching for key n-grams for less intuitive sequences. ultimately, the most revealing insights will be gained from a closer look at the texts, the speakers, and the situational variables; quantitative analysis alone can never provide a satisfactory picture (Simpson, 2004:41).
