What is the difference between abstract and summary? not abstract and conclusion?

Abstract is a short account of the paper. Summary is the concluding part of the work where an author will discuss about his present findings, especially in relation to the to the previous findings if any, and what can be pursued in future in the said context.  

What is the difference between abstract and summary? not abstract and conclusion?

The attached file may be of some help to you.

 Dear Abdulsamie

An abstract is a research proposed in short...

infact, a good abstract is self sufficient to communicate, in  short, what actually the whole document contains... and can serve the purpose of whole research lying there in... and you have to admit that it is equivalent to a publication... (that is why conference held all over come with a published abstract book, containing hundreds of abstracts)

and summary provides the results our outcomes of research conducted  in short...

remember that it is abstract that attracts readers at first sight...

abstract alone can serve the purpose of research paper...

THE DIFFERENCES BETWEEN A SUMMARY AND AN ABSTRACT The terms summary and abstract are often used interchangeably resulting in some confusion. This problem arises because there are two distinct types of abstracts – descriptive and informative. The informative abstract is another name for a summary; the descriptive is not. The descriptive abstract is usually only 2 or 3 sentences in length, hence it is not a summary or very informative. An informative abstract (summary) is an abbreviated version of the most significant points in a book, article, report or meeting. It is usually about 5% to 15% of the length of the original. It is useful because it condenses material, informing the reader of the original’s most important points.

The abstract is written for the potentially interested reader. The abstract should give an impression what the paper will be about. . It should be understandable for non-specialists and even for people from fields somehow far away. the abstract should include all the main aspects of the paper in an abbreviated form - the topic, the hypotheses, the participants and study design, and the results.

A summary sums up the paper. I am not sure if a paper needs a summary. A summary could be anywhere, even separate from the paper itself, so it's a bit more slippery.

'Abstract' is introductory part in brief & 'Summary' is concluding part of paper in brief

Ezeala C.C.’s view/definition may further help, namely: an abstract is a brief summary of a research article that emphasizes what is new, captures the salient features of the purpose, design, findings, and implications, and contains no unnecessary sentences or explanations (see: Ezeala and Ezeala, 2012, p. 142).

The following publications are helpful as to a further explanation/guidance of writing an abstract:

• Andrade, C. (2011) How to write a good abstract for a scientific paper or conference presentation, Indian Journal of Psychiatry, 53, 2, pp. 172-175.
• Bavdekar, S. B. and Gogtay, N. J. (2015) Writing an Abstract for a Research Manuscript: Providing an Honest, Succinct and Complete Summary, The Journal of the Association of Physicians of India, 63, 12, pp. 64-67.
• Ezeala, C. C. and Ezeala, M. O. (2012) Writing a Good Abstract: A guide to good abstract writing for medical science journal articles, Health Professionals Education in the Pacific, 18, 2, pp. 142-145.
• Hall, G. M. (2013) How to write a paper. 5th edn. Hoboken,USA: Wiley-Blackwell. (See: Titles, Abstracts and Authors, pp 33-41.)

Honestly, I copy this answer from the web, please check if it is enough.

EVALUATIVE SUMMARIES :

Evaluative summaries differ from other abstracts and summaries in only one way: your opinion of the material is included in the evaluative summary.

You should blend your assessment throughout the entire summary and not just lump all of your opinions at the end.

This lets the reader know what you thought of each point addressed in the article. These are some questions that you should answer for readers of your evaluative summary. Content Evaluation:

< How carefully is the subject researched?

< Is the material accurate and up-to-date?

< Is the writer or speaker objective?

< Does the work achieve the goal?

< Did the writer cover the topic adequately?

< Are there irrelevant materials in the work?

< Is the material relevant to the audience for whom you are writing your evaluative summary?

best wishes

Abstracts give the reader insights to the purpose, hypothesis, study design and results in condensed form.

Summary is more lengthy, and sums up main points of the research work, it may include the research problem and how it was tackeled, the methodology followed, type of data used or simulated data ( if any) and a detailed conclusions more than that in the abstract.

Abstract: Its a short note that express the contents of the work. ... One basic difference: An abstract is always at the beginning of a academic paper. A conclusion is always at the end. A summary could be anywhere, even separate from the paper itself, so it's a bit more slippery
