Summaries in everyday life

The importance of summaries

The ability to write an effective summary might be one of the the most important writing skill you possess.

You need to be able to summarize to be effective at writing demanded by your work, schoolwork, and it is a vital part of note taking too.

To answer questions such as “what was the movie about?” “how did the game go?” and “what did I miss in class today?” you must be able to summarize.  Your questioner doesn't want to know every line and action in the movie, every play in the game, or every word from class;  the question asks you to select the important details and summarize them.  Similarly, when you summarize a reading you need to be able to find the important data and then present it as clearly and concisely as possible.

Many organizations employ people to read newspapers, social media, news feeds and summarize relevant stories and articles. The more concise the summary the better, yet if any major details are omitted the purpose of the summary is lost - its readers will be uninformed on key aspects of the news and may make critical errors as a result.

Summaries in everyday life

 If we look around it clearly visible that we are surrounded by summaries. In fact, a great deal of information we consume are summaries. We may think about the summaries as forms of advertisement where the purpose is to catch the attention and attract.

Let's have a look at some examples. Of course this list incomplete.


1. Headlines: summaries of newspaper articles  

 A headline's purpose is to quickly and briefly draw attention to the story. For journalists and editors a headline is to provide the center of the story, the beating heart of what the story is about.


2. Table of Contents: summary of a book, magazine  

Table of Content, is a list of the parts of a book or document organized in the order in which the parts appear. It is a list that provides a quick overview of what the reader is going to find in the content.

The Table of Contents usually includes the titles or descriptions of the first-level headers, such as chapter titles in longer works, and often includes second-level or section titles within the chapters as well, and occasionally even third-level titles.



3. Digest: summary of stories on the same topic  

A digest format provides a sampling of favorite articles on many subjects from various monthly magazines, often condensing and rewriting them, and then combing them for convenience into one magazine. Well known examples are Reader's Digest, Golf Digest, Consumers Digest, and various electronic mailing lists.

4. Highlights: summary of an event (meeting, sport event, etc.) 

The purpose of a highlight is to provide an especially significant or interesting detail or phenomenon to draw reader's attention.

  5.  Abstract: summary of a scientific paper  

An abstract is a concise summary of a research article, review, thesis, conference proceeding or any in-depth analysis of a particular subject or discipline, and is used to help the reader quickly understand the paper's purpose. An abstract always appears at the beginning of a manuscript.
It is the point-of-entry for any given academic paper or patent application. Abstracting and indexing services for various academic disciplines are aimed at compiling a body of literature for that particular subject.

 

 6. Bulletin: weather forecast, stock market, news  

There are physical bulletin boards, typically made out of cork to pin messages and advertisments. And there are electronic bulletin boards which serve the same purpose as a physical bulletin board.
The purpose is to provide brief information snippets and essential facts. The emphasis is on brevity and facts.

  

7. Biography: resume, obituary  

A biography is a detailed description or account of someone's life. It entails more than basic facts (education, work, relationships, and death), a biography also portrays a subject's experience of these events.
A biography presents a subject's life story, highlighting various aspects of his or her life, including intimate details of experience, and may include an analysis of a subject's personality.

  8. Abridgment: of books 

Abridgement is a term defined as "shortening" or "condensing" and is most commonly used in reference to the act of reducing a written work, typically a book, into a shorter form.
A written work may be abridged to make it more accessible to a wider audience; for example, to make an adaptation of it as an audio book or a television show, to make a more convenient companion to an already established work, or to create a shorter reference version.

 

 9. Review: of books, music, plays 

A review is an evaluation of a publication, a product, a service or a company such as a movie, video game, musical composition, book, car, home appliance, or computer; or an event or performance, such as a live music concert, a play, musical theater show or dance show.
In addition to a critical evaluation, reviewers may assign the work a rating to indicate its relative merit.

  10. Scale-downs: maps, thumbnails 

A map is a visual representation of an area—a symbolic depiction highlighting relationships between elements of that space such as objects, regions, and themes.
It is to give us a quick visual orientation. Thumbnails are reduced-size versions of pictures, used to help in recognizing and organizing them, serving the same role for images as a normal text index does for words. In the age of digital images, visual search engines and image-organizing programs normally use thumbnails

  

11. Trailer: from film, speech, presentation  

A trailer or preview is an advertisement or a commercial for a feature film that will be exhibited in the future at a cinema. A book trailer is a video advertisement for a book which employs techniques similar to those of movie trailers.

Pictorial Knowledge Presentation - Text Summarization and Visualization Connected


In this post  I will present two powerful technologies for summarizing and visualizing information rolled out into a single web application. The result is a Visual Summary which is a very practical pictorial tool for presenting and recording knowledge.

Visual Summary - combining automatic summarization with automatic visualization


In our daily work, learning, communication we frequently summarize what we need to convey and very often present our information using graphical means to vividly express our thoughts. In this sense summarization and visualization are important techniques that we apply to effectively communicate, teach, explain, clarify, and inform.

As a human processes the summarization and visualization are time consuming and very demanding given our daily significant reading load.  It stands to reason that automating both summarization and visualization would rapidly increase the number of web pages and documents that we could summarize and visualize. And if such a system would produce an instant summary and at the same time present it also as a visual diagram, an interactive diagram, this would be a highly beneficial application. 

And indeed, Visual Summary by WebSummarizer offers such a solution.

Why is this significant?


The single impact of summarization is to establish a focus for our mind.

Not all information is equal:  some of it clearly is more important than the rest so making the distinction and providing relevance ranking is a vital feedback helping us with filtering and evaluating information.

Visual representation of information is useful because it opens up the way we think about data. It helps us with revealing hidden patterns, and highlighting connections between elements. And helps us remembering the details.

The main idea is the most important concept - the focus - is represented at the root of the visual summary.

Together, summarization and visualization, comprise a highly engaging, crystal-clear and dynamic way to present, communicate and understand complex information.

Combining the ability to integrate the Visual Summary with host of other systems makes the application a powerful companion for exploring the wealth of information available to us on our computers, tablets and smart phones.  

For the record, here are some general descriptions of automatic summarization and automatic visualization:

  • Automatic summarization is the creation of a shortened version of a text by a computer program. The product of this procedure still contains the most important points of the original text.
  •  Automatic text visualization aggregates the most important information around the key ideas and presents the information as clear preferably interactive diagram. This presentation makes it easy to understand, view and remember the key information. 

 Knowledge Bases and Visual Summaries


We can imagine that accessing collections of summaries offers much richer information choices than looking just at a summary of a single document. Further, we can imagine that aggregating collections of  summaries on many topics would provide a very fertile ground to seriously engage into knowledge discovery. 

In this scenario, we have a smartly organized repository of summaries indexed by topics. The topics are linked to the relevant summaries and to their sources so we always know where the information is coming from and what is the context of the information. Also, the convenient zoom-in feature allows to examine information in more details by navigating the dynamic Visual Summary.

The ultimate goal of creating and using knowledge bases is to speed up our understanding and reasoning about the contents of large and complex text collections. Such text collections are blogs, websites, newspapers, search engine results, digital libraries, social media, corporate documents, news feeds, etc.


Getting a knowledge snapshot of the key topics and the context helps with decision making, evaluations, recommendations and learning.
