Literature Mapping in Scientific Research: A Comprehensive Review

Accelerate scientific research with Literature Mapping: a comprehensive tool for knowledge discovery and data-driven insights.

Literature mapping is a process that involves analyzing and visualizing the scientific literature on a particular topic to identify research gaps, improve collaboration, and inform decision-making.

In this article, we list five benefits of literature mapping for scientists and researchers and show you types and tools to save your time and help you find better evidence.

What is Literature Mapping?

Literature mapping is a process that involves analyzing and visualizing the scientific literature on a particular topic. It includes systematically searching, collecting, and reviewing relevant studies, articles, and books published in a specific field or discipline.

The purpose of literature mapping is to provide a comprehensive overview of the current state of knowledge on a topic, identify gaps in the literature, and potential areas for future research. It can be useful for those who seek to conduct a systematic review, develop a research proposal, or explore new research areas.

Benefits of Literature Mapping

Here are five benefits of literature mapping for scientists and researchers:

• Identify research gaps : Literature mapping helps researchers to identify gaps in the existing research and to determine areas that require further investigation.
• Visualize the research landscape : By creating visualizations of the scientific literature, researchers can see the relationships between different research topics.
• Save time : Literature mapping can help researchers save time by providing an overview of the literature on a particular topic, including relevant studies and duplicated work.
• Improve collaboration : Literature mapping can help researchers to collaborate more effectively by providing a shared understanding of the research landscape. This improves communication, and facilitates the workflow between different disciplines.
• Inform decision-making : Literature mapping can help researchers to make assertive decisions. This can be especially useful for policymakers and other decision-makers who need to make decisions based on scientific evidence.

Types of Literature Mapping

Feature mapping.

Feature mapping is a technique used primarily in data analysis and machine learning to identify patterns and relationships between features of a dataset. It involves analyzing the data and plotting the relationships between different features of the dataset on a map or chart.

Some of the main features include:

• Identification of relationships : Feature mapping can help identify the relationships between different features or variables in a dataset. This can allow for better modeling and prediction of outcomes.
• Pattern recognition : By plotting the relationships between features of a dataset, feature mapping can help identify patterns and anomalies that may not be immediately apparent in the raw data.
• Visualization : Feature mapping often involves creating visual representations of the relationships between features of a dataset. This can help make the data easier to understand and interpret.
• Dimension reduction : When dealing with large datasets with many features, feature mapping can help reduce the dimensionality of the data. This can help simplify the data and make it easier to analyze.
• Data clustering : Feature mapping can also help identify groups or clusters of data points that share similar features. This can allow for more targeted analysis and modeling of specific groups within the dataset.
• Feature selection : Feature mapping can aid in the selection of the most important features from a dataset. By identifying the relationships between features, researchers can determine which features are most relevant to the outcomes they are trying to predict.

Topic Tree Mapping

Topic tree mapping is a technique used to visualize and organize the relationships between different topics or themes within a larger subject area. It involves creating a hierarchical structure of topics, with more general topics at the top and more specific subtopics branching out below.

Content Mapping

Content mapping is the process of creating a visual representation or map of the content of a document, website, or other information source. It involves breaking down the content into its constituent parts, organizing it according to a logical structure, and presenting it in a user-friendly and easily accessible way.

Taxonomic Mapping

Taxonomic mapping is the process of assigning different taxonomic categories to specific objects or organisms based on their characteristics, traits, and other distinguishing features. This mapping enables the organization and identification of different species and helps researchers and scientists to conduct various studies and experiments related to their classification, evolution, and diversity.

Concept Mapping

Concept Mapping is a visual representation of the relationships between concepts and ideas in a particular field. It involves identifying key concepts, and organizing them into a hierarchical structure. It can help to identify gaps in knowledge and aid in the development of new theories.

Rhetorical Mapping

Rhetorical mapping is a process used in communication studies and critical discourse analysis to analyze the structure and content of discourse. It involves creating a visual representation or diagram of a text or speech that identifies its various components, such as arguments, claims, evidence, and rhetorical strategies used to persuade the audience. Rhetorical mapping allows researchers to understand how the speaker or writer uses language and persuasion techniques to influence the audience’s beliefs and attitudes.

Citation Mapping

Citation Mapping involves tracing the citation history of a particular article, and identifying the articles that have cited it. This can help to identify the impact of the article on the field, and identify related research.

You are here, structuring your ideas: creating a literature map.

It is important to have a plan of the areas to be discussed, using this to indicated how these will link together. In the overall structure of the literature review, there should be a logical flow of ideas and within each paragraph there should be a clear theme, around which related ideas are explored and developed. A literature map can be useful for this purpose as it enables you to create a visual representation of the themes and how they could relate to one another.

A literature map (Cresswell, 2011) is a two dimensional diagrammatic representation of information where links are made between concepts by drawing arrows (which could be annotated to define the nature of these links). Constructing a literature map helps you to:

• develop your understanding of the key issues and research findings in the literature
• to organise ideas in your mind
• to see more clearly how different research studies relate to one another and to group those with similar findings.

Your map can then be used as a plan for your literature review.

As well has helping you to organise the literature for your review, a literature map can be used to help you analyse the information in a particular journal article, supporting the exploration of strengths and weaknesses of the methodology and the resultant findings and enabling you to explore how key themes and concepts in the article link together.

It is important to represent the different views and any conflicting research findings that exist in the literature (Newby, 2014). There is a danger of selective referencing, only including literature that supports your own beliefs and findings, disregarding alternative views. This should be avoided as it is based on the assumption that your views are the correct ones, and it is possible that you could miss key ideas and findings that could take your research in new and exciting directions.

Literature Reviews: A Working Definition

A literature review is a methodical or organized review of the published literature on a specific topic or research question designed to analyze--not just summarize--scholarly writings that are related directly to your research question. That is, it represents the literature that provides the context for your research and shows a correspondence between those writings and your own work.

Before you get started...

The past few years have seen an explosion of online tools designed to automate the process of doing literature reviews. These tools generally work by asking you to identify a relevant article (often called a "seed article") and use the metadata attached to articles (such as authors and keywords), or citations and reference lists to find related articles. Most tools offer some type of visualization feature to trace the connections between papers, and increasingly, tools offer summaries of the research content. These tools provide researchers with an option to at least partially automate some of their literature review work which can save a lot of time.

Things to keep in mind:

• Very little independent research has been done to test the reliability, scope, and accuracy of these tools
• In our own testing of tools that provide summaries of articles, we have sometimes found that summaries do not reflect the same key take-aways that we have identified
• Reproducibility of searches is questionable so they may not be the best choice for things like systematic reviews
• Because of the reliance on citation chaining, there is a built in bias towards heavily cited works which ends up creating a feedback loop that may cause you to miss relevant and/or newer materials
• Not everything is indexed in the data sets used by a given tool; this is particularly the case in the arts and humanities which are more oriented towards books
• Both the tools themselves, many of which are open access projects, and the indices they rely on may stop being updated/maintained, or go offline for a variety of reasons
• You still need to use a library to access full text in a majority of cases

NOTE: This is a rapidly evolving field and we will be updating this guide on a regular basis.

Powerful Tools for Mapping a Research Literature

Professor Courtney Page Tan , Assistant Professor of Human Resilience in the Department of Security and Emergency Services at Embry-Riddle Aeronautical University, has compiled a list of powerful literature mapping tools. You can use these tools to increase the scale and scope of the literature for your projects. Many provide stunning graphical displays of search results (Edward Tufte would approve).

Connected Papers lets you explore connected papers in a visual graph, beginning with a starter paper you select. You can start with a DOI, URL, or paper title. Purposes: (1) Get a visual overview of a new academic field; (2) Make sure you haven’t missed an important paper; (3) Create the bibliography to your thesis; and (4) Discover the most relevant prior and derivative works.

scite_ Smart Citations for Intelligent Research . Smart Citations allow users to see how a scientific paper has been cited by providing the context of the citation and a classification describing whether it provides supporting or disputing evidence for the cited claim. They claim a database of over 23 million full-text articles.

Open Knowledge Maps . Calling themselves a “visual interface to the world’s scientific community,” their tool allows you to start with a few keywords to search for literature on a topic. Results display the main areas at a glance, and papers related to each area. In addition to giving you an overview of the area, it helps you identify important concepts. They highlight open access papers in their search results.

Local Citation Network . You input an article using its DOI or a scanned copy containing DOIs and the program shows you suggested articles for you to follow up.

They explain that “This web app aims to help scientists with their literature review using metadata from Microsoft Academic and Crossref . Academic papers cite one another, thus creating a citation network (= graph) . Each node (= vertex) represents an article and each edge (= link / arrow) represents a reference / citation. Citation graphs are a topic of bibliometrics, for which other great software exists as well .

This web app visualizes subsets of the global citation network that I call “local citation networks,” defined by the references of a given set of input articles. In addition, the most cited references missing in the set of input articles are suggested for further review.”

Citation Gecko Gecko is designed to help you find the most relevant papers to your research and give you a more complete sense of the research landscape. Users start from a small set of ‘seed papers’ that define an area you are interested. Gecko will search the citation network for connected papers allowing you to quickly identify important papers you may have missed.

PRISMA Flow Diagram Generator . This is the most complex of the tools. It generates a graphical representation of the flow of citations reviewed in the course of a Systematic Review. Click here for an example.

Creating a Comprehensive Literature Review Map: A Step-by-Step Example

• backlinkworks
• Writing Articles & Reviews
• October 16, 2023

A literature review is an essential component of any academic research paper or thesis. IT involves examining existing literature, scholarly articles, books, and other sources related to your research topic. A literature review map acts as a visual representation of the concepts, studies, and theories that have been covered in the literature. In this article, we will guide you through the process of creating a comprehensive literature review map, step-by-step, to help you structure and organize your literature review effectively.

Step 1: Define Your Research Topic

The first step in creating a literature review map is to clearly define your research topic. Be specific and narrow down your focus to ensure that you have a manageable scope for your literature review. Take into consideration the research objectives or guiding questions that will shape your review.

Step 2: Identify Relevant Keywords

Once you have defined your research topic, identify the keywords and search terms that are most relevant to your study. Brainstorm a list of potential keywords that are commonly used in the literature related to your topic. These keywords will help you locate relevant sources during your literature search.

Step 3: Conduct a Thorough Literature Search

Using databases and search engines specific to your field of study, begin conducting a thorough literature search using the identified keywords. Take note of the key articles, books, and studies that are relevant to your research topic. In this step, IT is important to evaluate the credibility and quality of the sources to ensure that you are referring to reputable and reliable information.

Step 4: Read and Analyze the Literature

After collecting a substantial number of sources, carefully read and analyze each one. Highlight key concepts, methodologies, and findings that are relevant to your research. As you progress, make notes or annotations to help you remember important details and connections between different sources.

Step 5: Organize the Literature

Now that you have read and analyzed the literature, IT ‘s time to organize the information into a coherent structure. One effective way to do this is by using a literature review map. Start by creating categories or themes based on the concepts or theories that emerge from the literature. Group together similar ideas or findings to create a visual representation of the interconnectedness of the sources.

Step 6: Create the Literature Review Map

With your categorized information, you can now create the literature review map. This can be done using software such as Microsoft Word, PowerPoint, or dedicated mind mapping tools. Start with your main research topic in the center and branch out with subcategories based on the themes or concepts identified earlier. Connect relevant sources to each subcategory, illustrating how they contribute to the overall understanding of your research topic.

Step 7: Revise and Refine

Review your literature review map for coherence and completeness. Ensure that all the key sources are accurately placed within the appropriate category or subcategory. Check for any gaps in your coverage and make sure that the map represents a comprehensive overview of the literature on your research topic.

Q: How many sources should I include in my literature review map?

A: The number of sources you include will depend on the requirements of your research and the depth of analysis you aim to achieve. However, IT is generally recommended to thoroughly examine a range of sources, including both seminal texts and recent publications, to ensure a well-rounded and comprehensive literature review.

Q: How do I determine the credibility of the sources for my literature review?

A: Evaluating the credibility of your sources is crucial to ensure that you are basing your review on reputable information. Consider the author’s qualifications, the credibility and reputation of the publishing outlet, the presence of citations within the article, and the overall coherence and consistency of the research findings.

Q: Can I use a literature review map for disciplines outside of the humanities and social sciences?

A: Absolutely! While literature reviews are commonly associated with humanities and social sciences, they are applicable to any academic field. Whether you are conducting research in the sciences, engineering, or any other discipline, a literature review map will help you organize and present the relevant scholarly literature specific to your research topic.

By following these step-by-step guidelines, you can create a comprehensive literature review map that will serve as a valuable tool throughout your research. Remember to regularly update and refine your map as you progress in your studies. A well-organized literature review will not only demonstrate your knowledge and understanding of the field, but also provide a solid foundation for your own research and contribute to the wider scholarly conversation.

The literature review can serve various functions in the contexts of education and research. It aids in identifying knowledge gaps, informing research methodology, and developing a theoretical framework during the planning stages of a research study or project, as well as reporting of review findings in the context of the existing literature. This chapter discusses the methodological approaches to conducting a literature review and offers an overview of different types of reviews. There are various types of reviews, including narrative reviews, scoping reviews, and systematic reviews with reporting strategies such as meta-analysis and meta-synthesis. Review authors should consider the scope of the literature review when selecting a type and method. Being focused is essential for a successful review; however, this must be balanced against the relevance of the review to a broad audience.

3 Innovative Literature Mapping Tools for Citation Maps 

In the ever-evolving landscape of academic research, navigating through vast amounts of literature can be daunting. Enter innovative literature mapping tools, packed with unique features.

They simplify and revolutionise the way researchers interact with scientific literature, enhancing the efficiency and depth of literature reviews.

Let’s dive into how these tools are reshaping the approach to academic research.

Innovative Literature Mapping Tools

What is a literature mapping tool.

A citation mapping tool is a game-changer. Think of it as a detective tool that uncovers the intricate web of connections within scientific literature.

These tools visualise citation relationships, creating a citation map or literature map that guides you through the complex maze of scholarly papers.

One popular example is Inciteful, offering innovative literature mapping tools that not only track citation links but also analyse the context of the citation, revealing direct citation relationships and co-citation networks.

Imagine you have a ‘seed paper,’ a starting point in your literature review. A literature mapping tool then take this seed paper and branch out, finding papers:

• That cite it (direct citation relationships) or
• Those that share a thematic connection (co-citation). 

This forms a citation tree or network, showing you not just one paper but a cluster of similar papers, interconnected by their citation relationships.

More modern citation mapping tool also integrated AI. They not only map out citation relationships but also delve into the citation context or sentiment, offering a richer, more nuanced understanding of how papers are interconnected. 

Litmaps is a cutting-edge citation mapping tool that offers a unique approach to visualising the connections in scientific literature.

It’s designed to simplify and enhance the process of conducting a literature review, especially for researchers looking to map out the citation landscape of a specific topic.

At its core, Litmaps lets you visualise citation relationships in a dynamic, interactive manner. It works by creating a literature map that shows how different papers are connected through citations. 

You start with a ‘seed paper,’ and Litmaps builds a citation network around it, by:

• Identifying seminal papers,
• similar papers, and 
• Other papers that cite your chosen article.

This is particularly helpful for understanding the context and development of research in a given field.

One of the key features of Litmaps is its ability to create a citation tree. This tree not only shows direct citation relationships but also highlights co-citations. This gives you a deeper insight into how ideas and research are interconnected.

In terms of visualisation, Litmaps excels. It uses a similarity graph, not just a standard citation graph, to display connections.

This means you’re seeing a more nuanced representation of the literature, based on the similarity metric of papers, rather than just citation counts.

Litmaps also allows for a high level of customisation. You can filter papers based on:

• The number of citations,
• Publication date, and even
• Specific keywords.

This makes it a highly flexible tool for conducting systematic reviews and meta-analysis.

Litmaps also have a more user-friendly interface, and additional features like tracking the latest papers on a specific topic or a random set of systematic reviews.

Inciteful is an innovative literature mapping tool that stands out in the field of academic research for its unique approach to visualizing citation networks.

This tool is designed to make the process of literature review more intuitive and insightful, especially for researchers and scholars delving into new or complex fields.

When you use Inciteful, you start by selecting a ‘seed paper’. From this single paper, Inciteful creates a citation network, branching out to reveal not only papers that cite your chosen article but also those that are contextually related through co-citation and citation relationships.

This forms a comprehensive citation map, allowing you to see how various research pieces interconnect.

A standout feature of Inciteful is its visualization capabilities. The tool presents a citation graph, where each node represents a paper, and connecting lines indicate citation links.

This visualization helps you grasp the structure of scientific discourse in a field, revealing seminal papers, emerging trends, and key authors. You can then filter and sort papers based on keywords, number of citations, or publication date.

Inciteful isn’t just about numbers of citations; it delves deeper. The tool analyzes the context of citations, bringing to light the sentiment and relevance of each citation relationship.

This adds an extra layer of depth to your literature review, offering insights that go beyond traditional citation counting. Inciteful Incorporates metadata from various sources like:

• Google Scholar,
• Web of Science, and
• Microsoft Academic

Inciteful also ensures that its citation network is rich and current. The tool also supports importing bibliographic data in BibTeX format, making it flexible and adaptable to various research needs.

This makes Inciteful not just a powerful research tool but also a highly customizable one, suited for everything from quick overviews to in-depth systematic reviews.

Connected Papers

Connected Papers is a cool literature mapping tool that offers researchers and scholars an intuitive way to explore the citation network of a specific paper or topic.

It stands out compared to the other mapping tools for its user-friendly design and effective visualisation techniques.

Connected Papers takes a ‘seed paper’ of your choice, then generates a citation graph based on the seed paper, producing a visual network that displays how this paper is connected to others through direct citations and co-citations.

This network reveals the most relevant papers, showing you the ‘big picture’ of research trends and developments related to your topic.

The citation graph in Connected Papers isn’t just a simple map; it’s a detailed visualisation tool. Each node represents a paper, and the lines between them indicate citation relationships.

This visualisation allows you to easily identify:

• Research papers,
• Citations, and even 
• Emerging trends in the field.

You can see at a glance which papers are most cited and how they interlink, providing a comprehensive overview of the scientific landscape.

Connected Papers uses metadata and bibliographic information from databases like Google Scholar, Web of Science, and Microsoft Academic. This ensures that the citation network you’re exploring is both extensive and up-to-date.

It also supports importing data in BibTeX format, making it versatile for different research needs.

This tool is particularly valuable for researchers who are looking to map out the landscape of a new or complex field. It helps in identifying related papers that might not be immediately obvious, providing a deeper understanding of the subject matter.

Literature Review Made Easy, With Citation Map Tools

Litmaps, Inciteful, and Connected Papers represent the forefront of academic research tools, each bringing a unique approach to literature mapping.

They empower researchers with advanced visualisation, comprehensive citation networks, and user-friendly interfaces, making literature reviews more efficient and insightful.

As the landscape of scientific research continues to grow, these tools are invaluable allies in navigating and understanding the complex web of academic knowledge.

Manual Literature Mapping

Manual literature mapping is a method of locating an article that is highly relevant to your topic and using it as a starting point to connect you to other relevant literature. Below are the steps for manually mapping literature in the multidisciplinary database Scopus . 

Step 1: Find a highly relevant article on your topic. This could be an article from your advisor or one that you found by keyword searching in Google Scholar or a database. 

Step 2: Locate a record of the article in Scopus  by copy/pasting the title of your article into the search box.

Step 3: Explore connections by

• Look at the references to go back in time.
• Look at who has cited the article to go forward in time.
• Look at the author to see what else they have published.
• Look at keyword suggestions
• Look at related articles recommended by the database
