Research Paper Abstract Definition In Writing

An abstract is a brief summary of a research article, thesis, review, conferenceproceeding, or any in-depth analysis of a particular subject and is often used to help the reader quickly ascertain the paper's purpose.[1] When used, an abstract always appears at the beginning of a manuscript or typescript, acting as the point-of-entry for any given academic paper or patent application. Abstracting and indexing services for various academic disciplines are aimed at compiling a body of literature for that particular subject.

The terms précis or synopsis are used in some publications to refer to the same thing that other publications might call an "abstract". In management reports, an executive summary usually contains more information (and often more sensitive information) than the abstract does.

Purpose and limitations[edit]

Academic literature uses the abstract to succinctly communicate complex research. An abstract may act as a stand-alone entity instead of a full paper. As such, an abstract is used by many organizations as the basis for selecting research that is proposed for presentation in the form of a poster, platform/oral presentation or workshop presentation at an academic conference. Most literature database search engines index only abstracts rather than providing the entire text of the paper. Full texts of scientific papers must often be purchased because of copyright and/or publisher fees and therefore the abstract is a significant selling point for the reprint or electronic form of the full text.[2]

The abstract can convey the main results and conclusions of a scientific article but the full text article must be consulted for details of the methodology, the full experimental results, and a critical discussion of the interpretations and conclusions. Consulting the abstract alone is inadequate for scholarship and may lead to inappropriate medical decisions.[3]

An abstract allows one to sift through copious numbers of papers for ones in which the researcher can have more confidence that they will be relevant to his or her research. Once papers are chosen based on the abstract, they must be read carefully to be evaluated for relevance. It is generally agreed that one must not base reference citations on the abstract alone, but the content of an entire paper.

According to the results of a study published in PLOS Medicine, the "exaggerated and inappropriate coverage of research findings in the news media" is ultimately related to inaccurately reporting or over-interpreting research results in many abstract conclusions.[4] A study published in JAMA concluded that "inconsistencies in data between abstract and body and reporting of data and other information solely in the abstract are relatively common and that a simple educational intervention directed to the author is ineffective in reducing that frequency."[5] Other "studies comparing the accuracy of information reported in a journal abstract with that reported in the text of the full publication have found claims that are inconsistent with, or missing from, the body of the full article."[6]

Copyright[edit]

Abstracts are protected under copyright law just as any other form of written speech is protected.[citation needed] However, publishers of scientific articles invariably make abstracts freely available, even when the article itself is not. For example, articles in the biomedical literature are available publicly from MEDLINE which is accessible through PubMed.

Structure[edit]

An academic abstract typically outlines four elements relevant to the completed work:

  • The research focus (i.e. statement of the problem(s)/research issue(s) addressed);
  • The research methods used (experimental research, case studies, questionnaires, etc.);
  • The results/findings of the research; and
  • The main conclusions and recommendations

It may also contain brief references,[7] although some publications' standard style omits references from the abstract, reserving them for the article body (which, by definition, treats the same topics but in more depth).

Abstract length varies by discipline and publisher requirements. Typical length ranges from 100 to 500 words, but very rarely more than a page and occasionally just a few words.[8] An abstract may or may not have the section title of "abstract" explicitly listed as an antecedent to content. Abstracts are typically sectioned logically as an overview of what appears in the paper, with any of the following subheadings: Background, Introduction, Objectives, Methods, Results, Conclusions.[citation needed] Abstracts in which these subheadings are explicitly given are often called structured abstracts by publishers. In articles that follow the IMRAD pattern (especially original research, but sometimes other article types), structured abstract style is the norm.[citation needed] (The "A" of abstract may be added to "IMRAD" yielding "AIMRAD".) Abstracts that comprise one paragraph (no explicit subheadings) are often called unstructured abstracts by publishers. They are often appropriate for review articles that don't follow the IMRAD pattern within their bodies.[citation needed]

The hydrodynamics of dolphin drafting

by Daniel Weihs, Faculty of Aerospace Engineering, Technion, Israel Institute of Technology, Haifa 32000, Israel.

Abstract:

Background Drafting in cetaceans is defined as the transfer of forces between individuals without actual physical contact between them. This behavior has long been surmised to explain how young dolphin calves keep up with their rapidly moving mothers. It has recently been observed that a significant number of calves become permanently separated from their mothers during chases by tuna vessels. A study of the hydrodynamics of drafting, initiated inmechanisms causing the separation of mothers and calves during fishing-related activities, is reported here.

Results Quantitative results are shown for the forces and moments around a pair of unequally sized dolphin-like slender bodies. These include two major effects. First, the so-called Bernoulli suction, which stems from the fact that the local pressure drops in areas of high speed, results in an attractive force between mother and calf. Second is the displacement effect, in which the motion of the mother causes the water in front to move forwards and radially outwards, and water behind the body to move forwards to replace the animal's mass. Thus, the calf can gain a 'free ride' in the forward-moving areas. Utilizing these effects, the neonate can gain up to 90% of the thrust needed to move alongside the mother at speeds of up to 2.4 m/s. A comparison with observations of eastern spinner dolphins (Stenella longirostris) is presented, showing savings of up to 60% in the thrust that calves require if they are to keep up with their mothers.

Conclusions A theoretical analysis, backed by observations of free-swimming dolphin schools, indicates that hydrodynamic interactions with mothers play an important role in enabling dolphin calves to keep up with rapidly moving adult school members.

Abstract types[edit]

Informative[edit]

The informative abstract, also known as the complete abstract, is a compendious summary of a paper's substance including its background, purpose, methodology, results, and conclusion.[11] Usually between 100 and 200 words, the informative abstract summarizes the paper's structure, its major topics and key points. A format for scientific short reports that is similar to an informative abstract has been proposed in recent years.[12] Informative abstracts may be viewed as standalone documents.

Descriptive[edit]

The descriptive abstract, also known as the limited abstract or the indicative abstract, provides a description of what the paper covers without delving into its substance. A descriptive abstract is akin to a table of contents in paragraph form.

Graphical abstracts[edit]

During the late 2000s, due to the influence of computer storage and retrieval systems such as the Internet, some scientific publications, primarily those published by Elsevier, started including graphical abstracts alongside the text abstracts.[14] The graphic is intended to summarize or be an exemplar for the main thrust of the article. It is not intended to be as exhaustive a summary as the text abstract, rather it is supposed to indicate the type, scope, and technical coverage of the article at a glance. The use of graphical abstracts has been generally well received by the scientific community.[15][16] Moreover, some journals also include video abstracts and animated abstracts made by the authors to easily explain their papers.[17] Many scientific publishers currently encourage authors to supplement their articles with graphical abstracts, in the hope that such a convenient visual summary will facilitate readers with a clearer outline of papers that are of interest and will result in improved overall visibility of the respective publication. However, the validity of this assumption have not been thoroughly studied, and a recent study statistically comparing publications with or without graphical abstracts with regard to several output parameters reflecting visibility failed to demonstrate an effectiveness of graphical abstracts for attracting attention to scientific publications.[18]

Abstract quality assessment[edit]

Various methods can be used to evaluate abstract quality, e.g. rating by readers, checklists (not necessary in structured abstracts), and readability measures (such as Flesch Reading Ease).[15][19]

I. Types of Abstracts

To begin, you need to determine which type of abstract you should include with your paper. There are four general types.

Critical Abstract
A critical abstract provides, in addition to describing main findings and information, a judgement or comment about the study’s validity, reliability, or completeness. The researcher evaluates the paper and often compares it with other works on the same subject. Critical abstracts are generally 400-500 words in length due to the additional interpretive commentary. These types of abstracts are used infrequently.

Descriptive Abstract
A descriptive abstract indicates the type of information found in the work. It makes no judgments about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract only describes the work being summarized. Some researchers consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short, 100 words or less.

Informative Abstract
The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the researcher presents and explains all the main arguments and the important results and evidence in the paper. An informative abstract includes the information that can be found in a descriptive abstract [purpose, methods, scope] but it also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is usually no more than 300 words in length.

Highlight Abstract
A highlight abstract is specifcally written to attract the reader’s attention to the study. No pretence is made of there being either a balanced or complete picture of the paper and, in fact, incomplete and leading remarks may be used to spark the reader’s interest. In that a highlight abstract cannot stand independent of its associated article, it is not a true abstract and, therefore, rarely used in academic writing.


II. Writing Style

Use the active voice when possible, but note that much of your abstract may require passive sentence constructions. Regardless, write your abstract using concise, but complete, sentences. Get to the point quickly and always use the past tense because you are reporting on research that has been completed.

Although it is the first section of your paper, the abstract, by definition, should be written last since it will summarize the contents of your entire paper. To begin composing your abstract, take whole sentences or key phrases from each section and put them in a sequence that summarizes the paper. Then revise or add connecting phrases or words to make it cohensive and clear. Before handing in your final paper, check to make sure that the information in the abstract completely agrees with what your have written in the paper.

The abstract SHOULD NOT contain:

  • Lengthy background information,
  • References to other literature [say something like, "current research shows that..." or "studies have indicated..."],
  • Using ellipticals [i.e., ending with "..."] or incomplete sentences,
  • Abbreviations, jargon, or terms that may be confusing to the reader, and
  • Any sort of image, illustration, figure, or table, or references to them.
