A brief comprehensive description (frequently <100 words for conferences) of a piece of writing that highlights major points and findings and summarizes your interpretations and conclusions.
An effective abstract
To write an effective abstract, follow these four steps.
Reread your paper with the purpose of abstracting in mind. Look specifically for these main parts: purpose, methods, scope, results, conclusions, and recommendations.
After you have finished rereading your paper, write a rough draft without looking back at your paper. Consider the main parts of the abstract listed in step #1. Do not merely copy key sentences from your report. You will put in too much or too little information. Do not summarize information in a new way.
Revise your rough draft to
Correct weaknesses in organization and coherence,
Drop superfluous information,
Add important information originally left out,
Eliminate wordiness, and
Correct errors in grammar and mechanics.
Carefully proofread your final copy.
