Key phrases are all about being informative!

Tuesday, April 27th, 2010
 
A key phrase is defined as a meaningful and significant expression consisting of one or more words in a document. For example a keyword "information" is very general while phrases "information overload" and further "information overload syndrome" provide much better understanding.
 
Appropriately, key phrases serve as a highly condensed summary for a document, and they are used as contextual labels to supplement the title or they can be highlighted within the body of the document to facilitate users’ fast browsing and reading.
 
Key phrases are usually manually assigned by authors, especially for journals,  conference articles or back-of-the book indexes.  However, the vast majority of documents such as news, magazine articles, web pages do not provide key phrases because the manual effort of assigning key phrases is too expensive. Therefore it is useful to automatically extract key phrases from web pages to accompany the main content of the document.
  
Key phrases are all about being informative!
 
Informativeness tells us how well a phrase captures or illustrates the key ideas.  Practice shows that users prefer using key phrases in their searches because they are getting more accurate results.
 
Because informativeness depends on the background information - the context - the more context we have  the better is our understanding.
 
Context plays crucial role in rapid information analysis and synthesis. Software tools, such as Context Organizer,  that specialize in spotlighting the key phrases provide a convenient shorthand for researchers and writers.
 
Context Organizer immediately focuses on the essential information and helps with rapid reviews of large number of documents in short time. Quick reviews of the key phrases with relevant context provide practical clues as to the usefulness of the information.

There is a need to automatically create key phrases

Monday, April 26th, 2010
 
Key phrases are meant to serve multiple goals:
 
   1.  They enable the reader to quickly determine whether the given article is of interest
 
   2.  When key phrases are gathered in the cumulative index - the goal is indexing. They enable the reader to quickly find relevant content when the reader has a specific need.
 
   3.  A search that matches a given query term in the keyword field will yield a higher quality list of hits than a search for the same term in the full text of the documents.
 
Given the fact that we are inundated with information there is a need for tools that can automatically create key phrases. And paradoxically, although key phrases are very useful, only a small minority of the online documents provide key phrases.
 
The principle for choosing key phrases is that the key phrase list is relatively short  and it must contain only the most important, topical phrases for a given document.
 
Context Organizer  treats a document as a set of phrases which must be ranked in terms of relevancy. It  views key phrase determination as a classification problem.  The task is to classify content in the document into one of two categories: either it is a key phrase or it is not a key phrase. The software evaluates key phrases by the degree to which its classifications correspond to human-generated classifications.
 
A huge advantage of the product is that the use of Context Organizer does not require costly training. It works instantly. The applied genetic algorithm and statistical methods are applicable across any types of documents.
 
Key phrases serve diverse goals the main one being the ability to capture the most important topics of the documents.
 
And since a key phrase list can be read and judged in seconds the usefulness of this approach leads to practical applications. Once the key phrases are identified the contextual summaries are easily recognized and collected. The key phrases and summaries are a suitable candidates for mind mapping, generating briefings, reports, documents summaries,  indexes, back-of-the-book lists for browsing, profiling user interests, personalization of subscriptions and many more applications.
 
There are many ways to further customize summarization by creating keywords to watch and keywords to block lists. The biggest advantage of summarization is that it acts as content filtering applications. And in this sense it works in a similar way that we read text which is mostly by scanning and skimming.

We Cannot Have Too Much Information

Tuesday, April 20th, 2010
 
We are used to looking at information in a linear way. Typically when we read web pages and documents we are like hunters trying to spot the most valuable information that is hidden in the text.
 
Our mind directs us to filter information until we find the relevant pearls of wisdom we are searching for. The sifting through vast reams of content is not efficient and mostly tedious.
 
So the question is: what if we had an ability to quickly access the content according to our wishes? This could mean that  we could directly ask a retrieval system what we need and the system would give us relevant choices.
 
For example, if we were interested in a specific topic, the search would provide a rich selection of relevant summaries - not links only - directly pertaining to our interests.
 
So instead of getting a long list of links to documents containing our search term we would get a handy list of the most important excerpts! And all this without the need to analyze each link.
 
This way of using content makes a huge difference. Instead of being crushed by too much information to analyze, we have direct access only to information that is of immediate interest to us. No more we need to spend time on fruitless sifting and sorting. Instead we get the relevant information directly.
 
How this is possible? By organizing and indexing information according to the summaries. Very much similar to the way we used to access information using the back-of-the-book index. Only now we can build a web-based back-of-the-book index that serves as an intelligent shortcut to getting desired information quickly and accurately.

A summary is worth a thousand of words

Thursday, August 28th, 2008
 
A summary is a shortened version of the original. The main purpose of such a simplification is to highlight the major points from the genuine (much longer) subject, e.g. a text, a film or an event. The aim is to help the audience get the gist in a short period of time. (Wikipedia)
 
The way we learn, remember and quickly recall has a strong relationship to the way we are able to process information without overloading our senses.
 
If our goal in understanding information is to quickly extract and convey meaning, then the use of summaries is essential. Summaries can be the key to understanding and reducing complex information to indispensable facts.
 
We can say that summaries are the bare models of thoughts and that summarized information represents the authorʼs best goals and intentions.

The act of instantly summarizing a web page can be an accelerator to quick understanding. By seeing the keywords in context, we, the readers, can quickly understand, connect and retain new information.

 
Summarization is relevant to all information workers, irrespective of their expertise.
 
When we read, we always have to parse the text. We read and re-read to extract the main statements. We underline important ideas and arguments according to the main statement. We work hard to assemble all the pertinent facts in logical order. And once all of this is done we then check if the summary reflects the original conclusions.
 
All of these hard and time consuming tasks can be greatly facilitated with the use of Context Organizer. With the click of a button, the essential keywords, sentences and context are revealed and highlighted. The keywords serve as a back-of-the-book index to the key statements and facts.
  
You may think about the Context Organizer summaries as an instant help in making sense by focusing on the key facts and conclusions only.
 
Context Organizer summaries allow busy professionals to save time.  It helps them to daily sift through copious amounts of information and rapidly review, compare and analyze information.

Scanning and Skimming instead of Reading

Monday, August 11th, 2008
 

At a click of a button in the web browser, you instantly see the keywords and the context of the web page or Google search results.

Jacob Nielsen provided a revealing study on How Users Read on the Web:
“People rarely read Web pages word by word; instead, they scan the page, picking out individual words and sentences.”
 
 
There are different methods of reading for different purposes.
 
The technique we choose depends on the reason for reading; for example, we can read for pleasure, for information, or to complete an assignment.
 
If we are appraising or reviewing, we may just skim a document. If we are searching for specific facts, we may scan for particular keywords. To get detailed information, we need to dig deeper into the text.
 
In effect, we adjust our reading speed and our focus depending on our purposes.
 
When reading large volumes of information, skimming and scanning may be more practical than deep reading.
 
Usually scanning is the first thing that we do when we select a source for review. It helps answer such questions as:
 
·   Is this relevant to what I’m looking for?
·   Will this give me the answers I’m looking for?
·      Is there anything in this related to my interest?
In fact when we are scanning, we are zipping through the whole source, homing in on the important chunks. Scanning gives us a feel for the whole item; it works like a powerful filter and saves us time.
 
In practice, scanning is a particularly useful technique for reading web pages. For example, we scan Google search results rapidly checking for relevant keywords. We glance at the titles and summaries searching for phrases or keywords that relate to our search.
 
There is also a deeper rationale for scanning; when we scan, our minds are instantly matching the keywords with the purpose of our query. This instant contextualization is the main reason why scanning is a very effective filter for identifying the relevancy of information.
 
 Context Organizer comes with built-in automatic scanning and skimming filters.  At a click of the button in the web browser, Context Organizer instantly identifies the keywords and key sentences by relevance. That means that the users instantly know if the web page is important to them and what the focal points are.
  
Try out Context Organizer to help you with rapid scanning and reading.
