چکیده
مقدمه: اعتبارسنجی مقالات دسترسی آزاد، همواره از جمله دغدغههای جامعه علمی بوده است. از آنجا که تحلیل استنادی کمی در ارزیابی مقالات علمی با چالش روبهرو است، تحلیل استنادی محتوامحور از جمله عقیدهکاوی بافتار استناد، میتواند تصویر روشنتری از اعتبار آنها ارایه دهد. هدف از انجام پژوهش حاضر، بررسی عقاید استنادگران درباره مقالات پزشکی دسترسی آزاد و مقایسه آنها با مقالات دسترسی غیر آزاد مشابه بود.روش بررسی: این مطالعه به روش تحلیل محتوای کمی با رویکرد تحلیل استنادی عقیدهکاوانه انجام شد. اطلاعات مقالات از پایگاههای PubMed، بافتارهای استناد از پایگاه Colil و نمره عقیدهای بافتارهای استناد از SentiWords استخراج گردید. پس از پردازش زبان طبیعی متن چکیدهها، عناوین و بافتارهای استناد، شباهت کسینوسی مقادیر TF-IDF (Term Frequency-Inverse Document Frequency) محاسبه و مقالات دسترسی آزاد و غیر آزاد مشابه زوج شدند. دادهها با استفاده از آزمون Friedman و همبستگی مورد تجزیه و تحلیل قرار گرفت.یافتهها: اختلاف معنیداری در نمره میانگین عقیده مقالات دسترسی آزاد با مقالات دسترسی غیر آزاد مشابه وجود نداشت؛ اگرچه اختلاف استنادات آنها معنیدار بود. همچنین، همبستگی معنیداری بین فاصله عقیدهای مقالات دسترسی آزاد و غیر آزاد با شباهت متنی و بافتار استناد آنها مشاهده نشد.نتیجهگیری: اگرچه مقالات دسترسی آزاد بیشتر از مقالات دسترسی غیر آزاد، استناد دریافت کردهاند، اما عقاید استنادگران درباره این دو گروه مقاله تفاوت معنیداری ندارد. همچنین، آثاری که به لحاظ موضوعی با هم شباهت دارند، لزوماً وضعیت عقیدهای مشابهی را نشان نمیدهند. از اینرو، لزوم تحلیلهای محتوامحور برای تکمیل نتایج تحلیل استنادی کمی تأیید میشود.

چکیده [English]
Introduction: Scientific communities have always been concerned about validity of open-access articles. Given the challenges of quantitative citation analysis in evaluating scientific articles, content-based citation analysis, including opinion mining of citances, can bring about more transparent results about their validity. In view of this, the present study compared the opinions contained in citances about open-access and non-open-access articles.Methods: We used a quantitative content analysis method with citation and opinion analysis approaches. The citances, bibliographic, and bibliometric data were extracted from Colil and PubMed databases. Opinion scores were assigned to the citances through SentiWords. After processing the titles, abstracts, and citances, Cosine similarity of Term Frequency-Inverse Document Frequency (TF-IDF) values were calculated. The open-access and non-open-access articles were then paired by their similarities in abstracts, titles, and citances. The data were analyzed using Friedman test and Spearman correlation.Results: There was no significant difference between the open-access and non-open-access articles in terms of their opinion scores, despite a significant difference in citation advantages. The pairs’ citance and textual similarities had no significant correlation with their opinion distance.Conclusion: Although the open-access studies had citation advantage over their similar non-open-access peers, they showed no significant opinion distance. Besides, similar texts did not necessarily follow the same opinion patterns. Consequently, to complete the results of quantitative citation analysis, the content-based citation analysis is emphasized.
