Making a literature review is a complicated and time-consuming process. But what if you need to prepare one quickly or are too overwhelmed with other tasks?
Consider using AI for literature review writing. It can speed up your work, making it more effective. In this guide, we prepared tips to help you use ChatGPT and other instruments for your next lit. review in an ethical way.
📖 What Is a Literature Review?
A literature review lays the foundation for further research. While working on it, students examine books, articles, studies, and journal entries. This process requires careful selection and meticulous work with various credible sources.
The first goal is to gather all existing knowledge and insights on a particular topic. Then, you summarize, organize the selected data, and critically analyze it. Such a review provides an evaluation of the main arguments, strengths, weaknesses, methods, and findings you’ve highlighted in the sources. This way, you will demonstrate that you have read and understood how every work relates to a broader research question.
Features of a Good Literature Review
A literature review’s quality depends on the merit of your research and gathered evidence. While different institutions offer various guidelines for the composition and format of these texts, they should always contain several key elements.
To achieve the perfect outcome, you should:
- Analyze the ideas in the assessed literature instead of describing its findings.
- Explain the importance of the research topic.
- Find similarities and differences in evidence, data, and opinions from different sources.
- Identify the limits of research methods and controversial areas.
- Offer opinions and personal responses to different works.
- Organize ideas by themes instead of sources.
- Provide citations, a reference list, or a bibliography in the required academic style. You can use our free citation maker to do it effectively.
Main Types of Literature Reviews
Currently, college students and academics use six types of literary reviews. Their choice depends on the research design and approach required for a particular study.
📌 Systematic. In this type, students and academics synthesize literature in a particular topic. A systematic review follows a structured plan to establish, evaluate, and critique relevant research to minimize bias.
📌 Scoping. Scoping reviews examine the entire field, highlighting gaps and underscoring the need for further research. Their main goal is to identify the size and scope of available literature on a particular topic.
📌 Argumentative. This type of paper examines literature to support or refute an argument, assumption, or philosophical idea in related works. Argumentative reviews are known for their potential bias and ethical research problems.
📌 Theoretical. This type of review focuses on the conceptual side of issues, ideas, and phenomena. Theoretical evaluations establish relationships between theories and examine how they have been tested.
📌 Critical. Critical reviews evaluate and critique the strengths and weaknesses of academic works, aiming to challenge existing ideas and theories.
📌 Narrative. This type of paper offers a comprehensive view of a topic without a strict selection or methodology.
💡 How to Use AI for Literature Review: 7 Simple Steps
Every student knows that AI tools can improve academic writing, but not all of them know how to use AI to write a literature review. This can be due to a lack of practice or unfamiliarity with this technology.
However, it’s actually very easy! Just follow the steps listed below:
- Select a search engine. Google Scholar, SciSpace, and other engines use artificial intelligence to find the most relevant papers. Such tools understand the context of search requests and provide results even without the exact keywords.
- Explore AI tools. Check out different tools like Consensus, Elicit, and Scite. They help locate relevant literature for your study. Each platform covers different bodies of work, so research their content and focus areas before choosing a literature source. We will cover the most popular tools in the next section.
- Analyze the results. Once you obtain the search results, review them to ensure they are relevant to your topic. Many AI tools offer summaries of academic works, making it easier to identify key points. Advanced tools also assist researchers in finding crucial information across multiple papers.
- Organize your findings. At the start of your research process, organize the sources you’ll be working with. You can do it faster with AI tools and reference managers that generate citations automatically.
- Extract data. After you’ve found and organized the list of references, extract relevant information and seek patterns in the research. Elicit and other tools can assist you in this process and help you analyze crucial data.
- Create a draft. While AI tools can help outline your paper, it is important to write the literature review outline yourself. This demonstrates your understanding and ensures that you did the research independently. Read our article on how to avoid getting caught using ChatGPT and other AI chatbots to learn more.
- Write a literature review. Once the groundwork is over, begin writing your literature review. Tools like paraphrasers will assist you a lot. The end result should be original and tailored to your way of thinking and conducting arguments. After you finish writing, proofread the review and revise with grammar checkers and AI text finders.
