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.
Multi-document summarization is an automatic procedure aimed at extraction of information from multiple texts written about the same topic. 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.
The graphic is intended to summarize or be an exemplar for the main thrust of the article. It is not intended to be as exhaustive a summary as the text abstract, rather it is supposed to indicate the type, scope, and technical coverage of the article at a glance.
Auto edit summaries exist for several actions, if the user fails to provide an edit summary: Blanking a page; Replacing entire page with other text, removing more than 90% of the content of a page; Creating a new page (the first 200 characters of the article appear in the summary) Adding, changing, or removing a redirect; Reverting a revision
In these cases, you can often replace the entire paragraph with a single sentence that explicitly states the central idea. For example, if a paragraph shows how a character becomes increasingly stressed, replace it with "Bob becomes increasingly stressed". This is unnecessary in shorter plot summaries.
Human indexers focus their attention on certain parts of the document such as the title, abstract, summary and conclusions, as analyzing the full text in depth is costly and time-consuming. [3] An automated system takes away the time limit and allows the entire document to be analyzed, but also has the option to be directed to particular parts ...
Template:Information - the template that is used in the file's description summary, including the template's documentation; Wikipedia:Uploading images § File description page's Summary mark-up text - an example of the Information template with the parameters explained, designed to be copied and pasted for easier editing
Obviously when you're writing a plot summary, you probably won't go into as much careful detail in thinking about every decision—for the most part, some aspects, such as picking what is important and what's not is intuitive, and doesn't require a lot of analysis. However, this example gives a sense of the logic that underlies a good summary.
