A Study of Human Summaries of Scientific Articles
Table 2: Frequent unigrams and bigrams in headlines
['Unigrams result', 'Frequency 63', 'Bigrams (key,point)', 'Frequency 34']
Out of 85 summary authors 35 used headlines in their summaries. Such headlines are commonly used by human summarizers for dividing their summary into small logical parts. In order to determine which subjects prevail in creating summary subdivisions, we analyzed summary headlines text. From the table it seems that many of the subdivisions either refer to specific logical aspect of the paper (as hinted by words like “result”, “model”, “dataset” ) or convey summarizer’s take on the paper (“my two cents”, “key points”).
