4. What is a literature review?
• A body of text that aims to review the critical points of current
knowledge on a particular topic.
• A comprehensive survey of publications in a specific field of study or
related to a particular line of research.

5. What is the purpose of a literature review?
• Establish a theoretical framework for your topic/subject area.
• Define key terms, definitions, and terminology.
• Identify studies, models, case studies, etc. supporting your topic.
• Define or establish your area of study, i.e. your research topic.

6. Three Key Points on Literature Review
• Tell me what the research says (theory).
• Tell me how the research was carried out (methodology).
• Tell me what is missing, i.e. the gap that your research intends to
fill.

7. Terms to Know
• Citation “A reference to another source, like a published article.”
• Systematic Mapping Study “A secondary study that aims at
classification and thematic analysis of earlier research.”
• Bibliometrics “Statistical analysis of written publications, such as
books or articles.”
• Social Network Analysis “Examining and investigating social
structures through network theory.”

9. NAILS
• NAILS is a tool for performing statistics and Social Network Analysis
(SNA) on citation data.
• Bibliometric Network Analysis “Statistical study of connections
between publications.”
• NAILS is a free software; you can redistribute it and/or modify it
under the terms of the GNU General Public License.

11. Serives
• NAILS works on publications available for download from Thomson
Reuters Web of Science Core Collection.
• It analyses seven essential variables for each publication, which
includes the authors, keywords, publication forum, article type, and
cited articles.
• The analysis identifies, for instance, the most cited articles and
authors, most common keywords, and journals with most
publications.
8
12. Services (cont.)
• The analysis and statistics are accompanied with visualizations for a
quick data overview.
• Additionally, the system extracts the citation network data from the
literature.
• The citation network enables calculating how many times each
reference has been cite by a paper inside the analyzed dataset.
9
13. Services (cont.)
• NAILS also extracts and exports data about citation and author
cooperation networks that can be visualized (e.g. using Gephi).
• This dataset of citation connection can be used to calculate the
relative influence of publications in the network.

14. How to Analyse
• NAILS works on publications available for download from Thomson
Reuters Web of Science Core Collection.
• The user downloads the literature data from Web of Science and
uploads it to NAILS via a web interface (HAMMER).
• The system then removes duplicate records and performs an
exploratory data analysis on provided literature data.

16. Case Study and Important Links
• A sample data retrieved from Web of Science with the search term
of ”augmented reality education”.
• Important links:
• https://webofknowledge.com/
• http://nailsproject.net/
• http://hammer.nailsproject.net/

36. CSV Files
• CSV stands for comma-separated values.
• Files in the CSV format can be imported to and exported from
programs that store data in tables, such as Microsoft Excel.

55. Topic Modeling Output
• Topic modeling is a type of statistical text mining method for
discovering common topics that occur in a collection of documents.
• A topic modeling algorithm essentially looks through the abstracts
included in the datasets for clusters of co-occurring of words and
groups them together by a process of similarity.

59. Conclusion
• NAILS and HAMMER are valuable tools that can help you identify
relevant keywords, authors, references, etc.
• The output can be used to expand your research to guarantee a
thorough literature review.
