Abstract: The popularity of internet and availability of online resources has increased the demand for generating precise summary to be extracted from single or multiple sources. This has also necessitated the need for intensive research in the area of automatic text summarization. Over several decades, the knowledge scarcity problem has been addressed in different perspectives with varied domains and using different paradigms. This study intends to investigate some of the most relevant approaches for summarizing technical documents emphasizing empirical methods and extractive techniques for generating summaries of technical documents. The results were also tested with commercial summarizers and the investigation seems to be promising in terms of precision and recall.
