Abstract
From observations made by Robson (1993) who states that “the success of data collection should be assessed in relation to the specific research question”, it is felt necessary to study the aim as well as the fact that the most suitable unit of analysis will be sufficiently large to be considered as a whole but small enough to be referred as a relevant meaning unit during the analysis process (Graneheim & Lundman, 2004). Based on these criteria, the researcher tries to investigate that the study is carried out in the right direction which rest upon the credibility and essentiality of a content analysis of the literature accumulated for review.
Purpose: To measure the significance of literature reviews and the effectiveness of content analysis as analytic tool for the present research theme “Document Similarity Measures on e-resource Retrieval in agriculture and allied fields”. Content analysis is expected to enhance systematic literature reviews of various inductively derived sub-fields of Information Retrieval implemented for accessing information and data in Agriculture and allied fields.
Methodology: The present study is based on content analysis on reviews of 59 selected articles published between 1951 and 2020 that are retrieved after screening through the PRISMA software. Almost all related subtopics of Information Retrieval have been explored in the literature review compiled for the research topic. The analysis of the data is simultaneously supported with the data visualization by the application of the Tableau Desktop Public software.
Findings: Each document is assessed based on the contents of the documents collected for the study viz. year of publication, name of journals, number of authors , name of authors, research area, methodology , number of references cited in each paper, country to which author(s) belong. Collaborative research mostly conducted by authors with specialization in computer science and data science is seen. Documents compiled for the present study comprised mostly of comparative studies among the different Information Retrieval Models. Also it has been judged in several documents the effectiveness of Vector Space Model over the other IR models simultaneously verifying that content analysis is an imperative tool to identify whether the literature review conducted so far is progressing in the appropriate direction.
Research Limitations: The major limitation is the limited number of documents retrieved and considered for the content analysis thereby customizing them for empirical analysis and assessing the significance of the literature reviews in order to identify the variations in the various research studies.
Conclusion: The analysis, software used and findings derived is aimed at facilitating the Information Retrieval researchers with the idea of conducting literature reviews through content analysis approach.
