Introduction to Text Summerization

What is Text Summerization ?

Text Summerization is the process of summarizing long text into short piece of text. It's main focus is to only add necessary and important sentences and text into the final summary. The goal of Text Summerization is to provide a shorter version of the source text containing only important aspects of the source text. It can be used in if we want to get only important information from a very long source text. 


Why Text Summerization is used ?

Text Summerization provides us a shorter version of long text containing only the important and necessary points and aspects of the source file. It helps in ignoring irrelevant information from the source text. It saves the reader's time by reducing the text size. It is mainly used to make precise documents of  long publications.


How Text Summerization summerize the text ?

Firstly it separates the document sentence wise. Then it uses various word scoring and sentence scoring techniques to decide score's of individual sentences. Sentence scoring is the process of evaluating the sentence importance by using several scoring algorithms. Sometimes more then one sentence scoring technique is used simultaneously to find more accurate score of the sentence .Then sentences having high score are taken to include in the final summary. 


The system generated short summary is then compared with the golden summary(summary having highest matching score with the original document) to find the precision and f-score. Then the sentence scoring technique which gives highest precision score is used for converting long documents in shorted document.

Cuckoo Search Algorithm

What is Cuckoo Search Algorithm? Cuckoo search is an optimization algorithm used in Natural Language Processing. It was inspired by the obligate brood parasitism of some cuckoo species by laying their eggs in the nests of host birds of other species. Some host birds can engage direct conflict with the intruding cuckoos.  For example, if a host bird discovers the eggs are not their own, it will either throw these alien eggs away or simply abandon its nest and build a new nest elsewhere. Cuckoo search idealized such breeding behavior, and thus can be applied for various optimization problems. It has been shown that cuckoo search is a special case of the well-known (μ + λ)-evolution strategy. Cuckoo search (CS) uses the following representations: Each egg in a nest represents a solution, and a cuckoo egg represents a new solution. The aim is to use the new and potentially better solutions (cuckoos) to replace a not-so-good solution in the nests. In the simplest form, each nest has one...

Different Types of Text Summarization

Image
  Broad Classification: •            Single Document Summarization Ø    Given a single document to generate a summary   •            Multiple Document Summarization Ø    Given a group of documents to generate a summary out of it   •            Generic Summarization Ø    Summarize the content of a document   •            Domain Specific Ø    Text summarization aims at extracting the essential information from a text to produce a shorter version,  such as generating headlines for news and subject lines for emails.   •            Query-focused Summarization Ø    Summarize a document with respect to an information need expressed in a user qu...
