Using Artificial Intelligence for Literature Reviews

Literature reviews are known to be time-consuming. From finding the articles to reading and analyzing all the components of the publications, it can take a long time to conduct a literature review. However, AI-based tools can help researchers speed up the process.

AI-powered tools can quickly identify relevant studies, extract key themes and concepts, and even generate summaries.

In recent years, using AI for literature reviews has gained significant importance in academic research. Specifically, AI tools have revolutionized how scholars and students explore various sources, offering cutting-edge capabilities to fine-tune search terms and sift through full-text articles with ease. For instance, AI-powered suggestions help researchers identify relevant scholarly articles and research papers, streamlining the development of a thorough literature review. Tools like Semantic Scholar and Connected Papers provide insightful citation contexts and connect related research which saves time and adds detail and precision in summarizing the breadth of existing knowledge.

Conducting a literature review involves summarizing and discussing published ideas from various sources to build a comprehensive view of the current state of research. AI can significantly enhance this process by offering meta-analysis capabilities and helping researchers write summaries that encapsulate the essence of multiple publications. For example, AI can analyze PDF documents and extract key points that help you to write more concise and informative summaries. While all researchers should take responsibility for any AI-generated outputs they end up using in their research you can efficiently navigate through the sea of academic work using AI and save time.

Why use artificial intelligence for a literature review?

AI's ability to assist in literature reviews extends beyond just finding and summarizing articles. It can also play a pivotal role in the early stages of research projects by helping to refine research questions and identify gaps in the existing literature. For example, AI tools can scan a wide array of scholarly articles to identify emerging trends and suggest areas that warrant further exploration.

According to recent research, AI can help with problem formulation and identify and verify research gaps by analyzing large datasets (Wagner, Lukyanenko, & Paré, 2021). However, human judgment is crucial for nuanced and context-specific interpretations. While AI can significantly reduce the time and effort required for repetitive tasks in literature reviews, human interpretation and creativity are irreplaceable for insightful synthesis and theory development.

These tools have demonstrated considerable potential in automating and streamlining the literature review process, especially in the critical phases of screening and data extraction. However, several limitations need to be addressed, particularly regarding usability and the integration of more advanced AI technologies (Bolaños, Salatino, Osborne, & Motta, 2024). The usability issues, such as a steep learning curve and misalignment with user requirements, hinder the widespread adoption of these tools among researchers. Financial constraints also pose a barrier, limiting access to comprehensive functionalities in some cases.

Nonetheless, by integrating these AI-powered tools into the literature review process, researchers can enhance their efficiency, reduce the cognitive load associated with manual tasks, and focus more on the interpretative and theoretical development aspects of their work. The continuous development and improvement of these tools promise even greater support for researchers in the future, making literature reviews more manageable and insightful (Wagner, Lukyanenko, & Paré, 2021).

How can AI assist in literature reviews?

Finding literature

AI-powered tools like machine learning algorithms and natural language processing (NLP) can significantly streamline finding relevant literature. These tools can search extensive databases and digital libraries to identify articles, books, and papers that match specific keywords and topics. They can also recommend related works based on the content of already identified materials, saving researchers considerable time and effort.

Literature summaries

AI can assist in summarizing large volumes of literature quickly and accurately. Tools using natural language processing (NLP) can extract key points, themes, and findings from numerous articles and create concise summaries. This helps researchers grasp the essential information from a broad array of sources without having to read each one in full detail. Such summarization tools can be invaluable for literature reviews, providing a clear overview of the existing research landscape.

Analyzing text

AI can perform in-depth text analysis, identifying patterns, trends, and insights that might not be immediately apparent. Techniques such as sentiment analysis, topic modelling, and keyword extraction can reveal underlying themes and connections within the literature. This analytical capability allows researchers to draw more nuanced conclusions and identify gaps or areas for further study.

Screening for inclusion

During the literature review process, AI can assist in screening articles for inclusion based on predefined research criteria. Machine learning models can be trained to recognize relevant studies by analyzing abstracts and full texts, thereby automating the initial screening phase. This reduces the manual workload and ensures a more systematic selection process.

Quality assessment

AI's potential in quality assessment is moderate, as this step requires expert judgment to evaluate methodological rigour. Tools equipped with AI can provide initial insights about the quality of other studies by checking for common issues related to how transparently methods are described and verification checks authors conducted. By automating parts of the quality assessment, researchers can focus on more in-depth analysis and interpretation of high-quality studies.

Information extraction

AI tools can streamline the data extraction process by automatically identifying and extracting relevant data points from research articles. Machine learning algorithms can be trained to recognize and pull out specific types of information, such as statistical results, sample characteristics, and key findings. Tools equipped with AI can provide initial insights about the quality of other studies by checking for common issues related to how transparently methods are described and verification checks authors conducted.

AI tools are designed to handle large volumes of data efficiently, making the literature review process faster and more comprehensive. With the emergence of the tools, researchers are exposed to several tools they can use. From summarizing articles to assisting in the literature search, AI tools can assist researchers by saving time and providing new ways of analyzing data.

For example, Research Rabbit maps research papers so that researchers can visualize connections between papers, authors and topics. Some research discovery tools such as LitSonar facilitate database searches by automatically translating search queries into formats compatible with various literature databases, such as EBSCO, AIS eLibrary, and ProQuest.
