ساختار فکری دانش در حوزه کتابخانه دیجیتال: مطالعه هم‌واژگانی

هدف: هدف از انجام پژوهش حاضر بررسی و ترسیم ساختار فکری دانش در حوزه کتابخانه دیجیتال جهان با استفاده از تحلیل هم‌واژگانی است.روش: این پژوهش از نوع مطالعات کاربردی علم‌سنجی است که از تحلیل هم‌واژگانی و تحلیل شبکه رهیافتی استفاده شده است. جامعه آماری تولیدات علمی حوزه کتابخانه دیجیتال در پایگاه وب‌آوساینس است که در مجموع برابر 5655 رکورد بود. همچنین برای تحلیل و ترسیم شبکه از نرم‌افزارهای vosviewer، netdrow، spss و bibexecl استفاده شد.یافته‌ها: یافته‌ها نشان داد که کلیدواژه‌های digital library، information retrieval و library پربسامدترین واژه‌ها و بیشترین زوج‌های واژگان digital library و information retrieval هستند. شبکه هم‌واژگانی شامل شش خوشه با نام‌های مدیریت دانش و کتابخانه دیجیتال، ذخیره و بازیابی منابع دیجیتال، تعامل انسان و محیط دیجیتال و یادگیری الکترونیک، منابع و رسانه‌های الکترونیک، غربالگری مجازی و تحلیل داده‌های پزشکی است. چگالی شبکه برابر 0.24 و میانگین شاخص مرکزیت برابر 6630/ است. مطابق نمودار راهبردی خوشه‌های مدیریت دانش و کتابخانه دیجیتال و غربالگری دیجیتال خوشه‌های توسعه‌یافته هستند و نقش محوری دارند. خوشه منابع و رسانه‌های الکترونیک اگرچه نقش محوری دارد ولی توسعه‌‌نیافته و نابالغ است. سایر خوشه‌های موضوعی خوشه‌های حاشیه‌ای بوده و موضوعات نوظهور هستند و به‌قدر کافی درباره آنها پژوهش نشده است.

the intellectual structure of knowledge in the field of the digital library:a co-word study

introduction: today’s digital library field is diversified, developed, and interdisciplinary. so that the study in its various aspects is always evaluated as one of the essential topics in scientific fields and can be the origin of significant research, the purpose of this study was to investigate and plot the intellectual structure of knowledge in the field of digital library in the world using co-word analysis. methodology: this research was a type of applied scientometric study using co-word and network analysis. the statistical population was all publications in the digital library field in the web of science core collection (woscc), equal to 5655 records. vosviewer, netdraw, spss and bibexecl software were also used to analyze and plot the network. findings: the results showed that the keywords “digital library,” “information retrieval,” and “library” were the most frequent words, and the most pairs of words were “digital library and information retrieval.” the co-word network includes six clusters called “knowledge management and digital library,” “storage and retrieval of digital resources,” “the interaction between digital and non-digital environments,” “e-learning, electronic resources and media,” and “virtual screening and medical data analysis.” the network density is .24, and the average centrality index is .663. the co-word network of the digital library field showed that the keyword “digital library” was the most central term and played the leading role in this network. the network’s density was 1290, which was not favorable. this case showed that the sub-domains within the clusters and inter-cluster connections, or the lack of research orientation to the technical issues of content, software and services as the three main elements of digital libraries and single domains. there was a lack of balance between theoretical and applied interdisciplinary research in this field. of course, the low density of the network also indicated that the subjects of the library field had been researched more in a specialized way, and less communication has been established between these fields, which is one of the weaknesses of this field.according to the strategic diagram, knowledge management clusters and digital libraries and digital screening are developed clusters and play a pivotal role. although pivotal, the electronic resources and media cluster was underdeveloped and immature.other subject clusters were marginal and emerging topics that were not sufficiently researched.conclusion: in general, this research showed that most of the publications in the field of digital libraries of the world had been done on the subjects of information retrieval, university libraries, user studies, the internet and copyright. considering that the network density of the digital library field is low, it is clear that researchers have neglected its interdisciplinary fields and the subjects of this field have little connection with each other. by reviewing the clusters obtained, it is concluded that the clusters of knowledge management, digital library and virtual screening have the central role of research, and most of the publications were carried out in this field the other hand, even though the clusters of storing and retrieving digital resources, human and environment interaction. digital and electronic learning were the primary and important topics in the digital library field. they were emerging, marginal and underdeveloped topics and researchers should direct most of their research in this direction so that these fields also reach a favorable state. in general, the structure of the intellectual network of the digital library field was fragmented, and to create a link between the structure of this network, research should be removed from being single-domain and theoretical and applied interdisciplinary research should be conducted.
