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.

It is quite fast and practical process to automatically summarize and aggregate the summaries into knowledge bases. WebSummarizer provides Wikipedia Knowledge Base which holds summaries of over 3 million articles indexed by almost 5 million keywords with an instant access to 30 million summaries.

The following two examples provide real Visual Summaries generated by WebSummarizer. You can open each of the topics and examine the context.

Publishing of the visual summaries in blogs and websites is as simple as inserting a YouTube video.
