چکیده
هدف: جستجوی معنایی به جستجویی فراتر از جستجوی سنتی یعنی انطباق و تطبیق کلیدواژه‌­های درخواست جستجو با کلیدواژه‌­های اسناد و مدارک موجود در سیستم اطلاق می­‌شود و به دنبال درک معنی و روابط معنایی بین کلیدواژه­‌های موجود در درخواست جستجوی کاربران است که با توسعه و گسترش وب معنایی و هستان­‌شناسی­‌ها روی کار آمده است. این نوع جستجو به دلیل دارا بودن مزایا و کاربردهای زیاد بسیار مورد توجه کاربران و پژوهشگران است ولی در کنار مزایا و برتری­‌های زیادی که نسبت به جستجوی سنتی و کلیدواژه‌­ای دارد، اشکالات و پیچیدگی‌­هایی نیز دارد که برطرف­‌سازی این اشکالات منجر به بهبودبخشی و ارتقای جستجوی معنایی شده و کمک شایان توجهی به کاربران می‌­نماید. از این رو، بررسی و سنجش جستجوی معنایی توسط کاربران، هدف اصلی پژوهش حاضر است.
روش­ پژوهش: پژوهش حاضر از نوع کاربردی، رویکرد آن کمّی و روش آن پیمایشی بوده است. ابزار گردآوری داده­‌ها پرسشنامه محقق‌ساخته بوده و جامعه آماری آن 189 پژوهشگر ایرانی بود که حداقل یک مقاله پژوهشی نمایه شده در پاب‌مد در زمینه بیماری کوویدـ19 منتشر کرده بودند.
یافته‌­های پژوهش: از دیدگاه پژوهشگران ایرانی در پایگاه پاب‌مد، میزان جامعیت و مانعیت در حد متوسط (3)، میزان شکاف معنایی نسبتاً زیاد (3<)، میزان صحت و دقت در بازیابی نتایج در حد متوسط (3)، میزان ارتباط مفهومی در حد متوسط (3)، میزان بازیابی مفاهیم معنی‌دار چندکلمه‌ای، در حد متوسط (3)، میزان بهبودبخشی و ارتقای عملکرد کلی در جستجوی معنایی نسبتاً زیاد (3<) بوده است.
نتیجه­­‌گیری­: نتایج پژوهش به طور کلی نشان داد که جستجوی معنایی، جستجویی پویا و چالش‌­برانگیز است که با وجود نقاط قوت و فواید و مزایای گوناگون برای کاربران در امر پژوهش، هنوز ضعف‌­ها و اشکالاتی نیز دارد که می­‌بایست هرچه بیشتر توسط کارشناسان پشتیبان جستجوی معنایی مانند طراحان هستان­‌شناسی برای سیستم جستجوی معنایی، مورد بررسی و تجدیدنظر قرار گیرد، برطرف­‌سازی این ضعف­‌ها و اشکالات، موجب می­‌شود که جستجوی معنایی بتواند به شکل بهینه­‌تری پاسخگوی پژوهشگران در امر پژوهش باشد و در نتیجه پژوهشگران و کاربران به نتایج غنی‌­تری جهت تدوین آثار پژوهشی خود دست یابند.

چکیده English

Objective: Various studies show that lexical or keyword search is not enough, because in this search the meaning of words and semantic relationships between keywords are ignored and semantic understanding is not achieved in this search. The purpose of this research is to investigate and measure the semantic search of users. Semantic search refers to a search that goes beyond the traditional search, i.e., the matching of the keywords of the search request with the keywords of the documents in the system and seeks to understand the meaning and semantic relationships between the keywords in the user's search request, which is used with the development and expansion of the semantic web and ontologies. The focus of this search is on obtaining a higher level of meaning from documents and inquiries and based on its content, which this high level meaning may be provided by ontologies. Semantic search expands the meaning and seeks machine understanding of the user's intent, query request and relationships between words and elevates the user's search strategy to a meaningful experience. In fact, semantic search describes the effort to produce accurate results by understanding the searcher's intent, texture and context of the query request, and the relationship between words. This search is of great interest to users and researchers due to its many advantages and applications. But besides the many advantages, it has over traditional and keyword search. It also has some problems and complications that elimination of these problems leads to the improvement and promotion of semantic search and helps users a lot.
Methodology: The present study is quantitative in terms of approach and applied in terms of purpose, which has been done by survey method. The data collection tool was a researcher-made questionnaire. The statistical population of the study was 189 Iranian researchers who had published at least a research article on COVID-19, which Indexed in PubMed.
Findings: Based on the research findings, from the perspective of Iranian researchers, the degree of recall and precision to semantic search in the PubMed is moderate (3). The amount of semantic gap in semantic search is relatively high (>3), the degree of accuracy and precision in retrieving results in semantic search is moderate (3), the degree of conceptual relevance in semantic search is moderate (3), the rate of retrieval of meaningful multi-word concepts in semantic search is moderate (3) and the rate of improvement and upgrade of overall performance in semantic search is relatively high (>3) in semantic searches at the database has been extensive.
Conclusion: The results of the research in general showed that semantic search is a dynamic and challenging search that despite its various strengths and advantages for users in research, but still has its weaknesses and drawbacks that should be reviewed and revised by semantic search support experts such as ontology designers for the semantic search system. Understanding, identifying, and eliminating these weaknesses and problems, make semantic search to be a better way to respond to researchers for their research, as a result, researchers and users can achieve to richer results for compile their research work.
