An abstract is a brief summary of a research article, thesis, review, conference proceeding, or any in-depth analysis of a particular subject and is often used to help the reader quickly ascertain the paper's purpose. [1]
An executive summary (or management summary, sometimes also called speed read) is a short document or section of a document produced for business purposes. It summarizes a longer report or proposal or a group of related reports in such a way that readers can rapidly become acquainted with a large body of material without having to read it all.
For example, the set cover problem is a special case of submodular optimization, since the set cover function is submodular. The set cover function attempts to find a subset of objects which cover a given set of concepts. For example, in document summarization, one would like the summary to cover all important and relevant concepts in the document.

The resulting summary report allows individual users, such as professional information consumers, to quickly familiarize themselves with information contained in a large cluster of documents.
An excessively detailed article is often one that repeats itself or exhibits writing that could be more concise. The development of summary-style articles tends to naturally clear out redundancy and bloat, though in a multi-article topic this comes at the cost of some necessary cross-article redundancy (i.e., a summary of one article in another).
For example, the American Journal of Physics (AJP) specifically advises authors that an introduction “need not summarize”. Instead, the introduction can provide “background and context”, and/or indicate “purpose and importance”, and/or describe the raison d'être for an article (i.e. motivation) in a way that is “informative and ...
