Final -- Methodology

Introduction and abstracts are similar. They both serve as a summary, indicating the reason, the topic and maybe to some extent the result of the article. In order to compare them, a corpus of 12 research articles is adopted. The articles should be chosen in a variety of sources, from conference papers to students' dissertation in biomedical engineering field, with different length as a possible factor affecting the structure of introductions and abstracts. In this paper, the sources are journals, conferences, and dissertations. Each has 4 articles, written in recent years. Another possible factor is the purpose of the article, including to create a literature review of the area, to implement an algorithm, or to present a experimental finding. Such differences in purposes are also considered to be taken into account during the setup of the corpus.
Since CARS model is reliable and widely used, each introduction is analyzed under this model to see which moves it has. And then, to contrast with the introduction, the corresponding abstract is examined by CARS model. The research focus is counted as move one or two, while the methods used and findings are move three. The length of each move is also examined in a standard that moves less than 1/4 of the section are counted as "short", and those longer than 1/2 are counted as "long"; move length in between is "medium". Afterward contrast is made to see whether they are coherent with introductions, and why they differ if the two parts have the same structure.
