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.
