Different academic disciplines have different research methods and requirements. Social sciences or hard science abstracts will typically include the parts of a research experiment. Abstracts in the humanities will often discuss the hypothesis being investigated and the conclusion.
Conferences and journals may have specific requirements for abstract submissions. Be sure to review the requirements prior to writing an abstract for your project.
Informative abstracts are generally used for documents pertaining to experimental investigations, inquiries, or surveys. The original document is condensed reflecting its form and content and provides quantitative and qualitative information.
Indicative abstracts simply describe what the research project is about.
