Brain overload: device too busy


It seems that the 
genius of connectedness offers us too many tempting directions to follow all at once. 

How often do you feel like the student in Gary Larson’s Far Side cartoon, and are tempted to say, “Mr. Osborne, may I be excused? My brain is full.”





A disk device can become so overwhelmed with Input / Output requests that at one point it will flash some warning messages asking you to increase your storage, or defragment it, or delete unneeded files. 

But what can we do when our brains are overwhelmed with information?

With all the benefits of the information and communications revolution, we also experience a well-known dark side: information overload and its close relative, attention deficit.

For example, in this age of social media, we create informational flows of near unrestrained magnitude from countless sources. In effect, the sheer amount of information threatens to hide really valuable information.

The traditional process of ‘filter-then-publish‘– done by professional editors – has been inverted to ‘publish-then-filter‘. So now instead of relying on professional editors and librarians to make recommendations, we have to become experts ourselves.

The curious thing about this state is that seemingly accidental recommendations from many sources sometimes result in remarkably high quality ideas – see crowdsourcing.org 

The challenge here is seeing how quickly we can discover them in the atomized universe; this is quite time consuming, which often leads to our brain overload

In parallel to the free-for-all publishing world, we also see trends for using collaborative methods for producing both aggregated and authoritative content that takes advantage of the limitless Web sources and yet can be trusted. Examples of such trends are Wikipedia and professional wikis. This community approach, with a peer review process, for sharing knowledge and learning, manifests our need for creating dependable and trustworthy information sources.

It seems that the genius of connectedness offers us too many tempting directions to follow all at once. Connectedness provides us with a very unrestrained way of seeing events, people, and the world where we are pressed hard to make sense from all the atomized information bits hitting us. This is why we are increasingly turning our attention to such applications as data mining, text mining, and big data.

Deep down, until there is a unified theory of the web, we often need to reach for some authoritative and curated content to keep us on dry land and save us from drowning in information overload and fragmenting our attention.

A Case For Knowledge Base Driven Information Mining – A WebSummarizer Use Case



We use terms like “knowledge economy” (Peter Drucker) , “knowledge as the fuel for innovation” (Nonaka) to emphasize the value we put on knowledge.
Putting knowledge to work requires tools enabling the gathering and structuring relevant information as factors driving innovation, creativity, and  invention.  In practice tools and techniques are tangible instruments of applying knowledge to solving real life challenges.

This is especially important in modern information society “where the creation, distribution, use, integration and manipulation of information is a significant economic, political, and cultural activity”. (see here)
Both concepts - knowledge economy and information society - are closely related by its emphasis on increasing technological capacity to store,  analyze and compute information as bases for data mining and discovery.

In our daily practice we can see the that a direct impact of knowledge economy is measurable in the explosion of scientific and medical discoveries, technological  patents and rapid research progress.

Information overload and information wealth

On a practical human scale we are facing information overload – a condition described as “the difficulty a person can have understanding an issue and making decisions that can be caused by the presence of too much information.” (see here)
Clay Shirky operationally defined information overload rather as a case of filter failure in his famous talk at  Web 2.0 Expo NY:  "It's Not InformationOverload. It's Filter Failure"




In reality we should rejoice and take advantage of the fact that we have unprecedented in the human history access to information wealth. And to cope better with information wealth we need automated  smart tools allowing us to take advantage of this unparalleled access to information.

Let’s take a practical case from our daily work. Research tells us that we spend almost  one third of our time searching for relevant information.  Of course finding relevant data is critical to our productivity but  spending one third of our productive time on searches leaves not much time on the actual creative usage of our findings.
On one hand we have the challenges with large data sources that includes capture, storage, and search of relevant information and then we need effective tools for sharing, analysis, and visualization. On the other hand all of us can benefit from knowledge mining tools allowing us to concentrate on applying knowledge instead of using our precious time on inefficient searches. 

Knowledge Base – practical tool set for discovery
In short knowledge base allows us to see how different pieces of information are inter-connected! This is the principle of how the Web works: it is all about linking web pages.

However, what is even more useful is to link the topics that are discussed on those web pages with related topics on other pages. This allows are to purely look at the relationships as a family of connections without the distraction of seeing the the unrelated information.  This allows us to focus on the topic in context of its relationship, correlation, influence, meaning, to other topics and contexts. Such information filters help with understanding and conveniently provide facts and insights to form our judgment and decisions.

Here is an example of Visual Knowledge Map. The topic is "Learning". The sources for generating the Visual Knowledge Map are numerous articles in Wikipedia that address the subject of learning in rich context. The Visual Knowledge Map was generated by WebSummarizer.

The Visual Knowledge Map is interactive. You can click on the + and - signs to zoom in and zoom out.

Visual Knowledge Map - graphical discovery search tool

Visual Knowledge Map is a graphical search tool that visually outlines related keywords and summaries.

Visual Knowledge Map is a part of the WebSummarizer, BlogSummarizer and WikiSummarizer family of products.

When you enter keywords into the Visual Knowledge Map tool, it gives you a set of topics related to your search terms and displays them as a visual interactive map. Then, for each of the discovered keywords, the tool provides ten additional keywords to broaden your discovery context.

The visual nature of the Visual Knowledge Map makes it interactive, easy to use and share.

As you click on a keyword, related topics appear next to your keyword. When you click on the keyword, you get an instant visual summary, based on a relevant Wikipedia article.

Here is an example of the Visual Knowledge Map tool using the Wikipedia knowledge base for text mining and generating visual summaries of the keywords. Let's look at the keyword "Internet" as a Visual Knowledge Map.

To explore the power of the knowledge map, please click on the Expand All and Collapse All plus and minus signs directly in the blog to see how the knowledge map works.

It is also possible to add different content sources for creating knowledge bases; you are not limited to Wikipedia. BlogSummarizer  also supports the rapid creation of knowledge bases from blogs hosted on WordPress and Blogger platforms. Corporate, government, professional, and academic digital libraries can also be used to create customized knowledge bases.


In short, the Visual Knowledge Map tool offers practical and interactive ways of finding related keywords, seeing essential summaries, and building your own knowledge maps in an interactive and visual manner.


Visual, Valuable and Easy to Use

As soon as you try the Visual Knowledge Map tool, you will see how valuable it is and just how easy it is to increase your productivity, your ability to brainstorm and to communicate clearly.

Let’s face it: identifying every single keyword related to the subject of your analysis and research can be overwhelming. That’s why having instant access to the Wikipedia knowledge base and other specialized knowledge bases is essential; the accumulated knowledge buried in millions of documents is instantly at your disposal.

And if you add the ease of publishing in your blogs and webpages so everyone with a browser can benefit from your visual knowledge map it makes it a great tool for research, learning, collaboration and brainstorming. 

How smart is the Visual Knowledge Map tool?


It allows you to leverage Wikipedia and blog knowledge bases to build themed keyword knowledge networks and comes with many powerful and user-friendly features.

  1. Rapid brainstorming help: the Visual Knowledge Map tool takes the guesswork out by taking your keywords and turning them into themed knowledge maps.
  2. The Visual Knowledge Map tells you (with a plus sign) that there are more options for expansion with certain keyword sets.
  3.  There is an editor tool that allows you to add, delete, and edit your own keywords and summaries.
  4. You can generate a summary of any keyword bases in the Wikipedia knowledge base, which is a great shortcut for accessing essential facts and building your own visual knowledge maps.
It is a great shortcut for rapid access to essential facts and building your own visual knowledge maps.

A word of caution: not all results will be relevant to your topic. The Visual Map Tool is not a human brain; however, you can select and add keywords according to your needs. When you peek into Wikipedia's brain, you are going to get results that encompass the entire context of about 4 million articles. That's a lot of brainstorming power, right? 

The non-relevant results are just as valuable as those that you want to keep because they show you how Wikipedia applies your keywords within its huge content which may help you expand your views. This is why using the Visual Knowledge Map tool will help you  discover many gems that you may never have normally unearthed.

You can try the Visual Knowledge Map tool in any of these products, depending on your needs:
 WebSummarizerBlogSummarizer and WikiSummarizer

When you can visually share and communicate your knowledge with others, everyone benefits. This is why the  Visual Knowledge Maps are easy to publish in your blogs and web pages; everyone with a browser - on any device - can benefit from your visual knowledge map. 

This makes the Visual Knowledge Map tool a great help in your research, learning, collaboration, and brainstorming endeavors.
