Edmundson (1969) describes a system that produces document extracts. His primary contribution was the development of a typical structure for an extractive summarization experiment. At first, the author developed a protocol for creating manual extracts, that was applied in a set of 400 technical documents. The two features of word frequency and positional importance were incorporated from the previous two works. Two other features were used: the presence of cue words (presence of words like significant, or hardly), and the skeleton of the document (whether the sentence is a title or heading). Weights were attached to each of these features manually to score each sentence. During evaluation, it was found that about 44% of the auto-extracts matched the manual extracts.
