Abstract
En 中文
For many purposes, downsampling and using downsampled corpora are popular ways of extracting research data from larger text collections. Whilst most benefits of downsampling are gained from using it as a tool for qualitative inspection, it is not uncommon that the use of concordance or downsampled corpora is extended to collocation extraction. This is done with the underlying assumption that differences between concordance corpus or downsampled corpus and full corpus are trivial in this regard. This paper reports on results from an analysis, where this assumption was specifically tested. The results show, that whilst there can often be a relatively high degree of agreement between the two methods, they cannot be relied upon to produce correlating rank-orders or overlapping top collocate lists in every case. Further, the difference was more marked in the case of content words in contrast to function words.
