Background and Aim: The main aim of Information storage and retrieval systems is keeping and retrieving the related information means providing the related documents with users’ needs or requests. This study aimed to answer this question that how much are the system relevance and User- Oriented relevance are matched in SID, SCI and Google Scholar databases.
Method: In this study 15 keywords of the most repeated ones that were related to “Human Information Interaction” and its subheadings were selected and searched both in Persian and in English in the mentioned databases for two one week periods. The results were arranged according to the system relevance based on the retrieval and displaying order. From each search the first 10 results were selected and sent to the subject experts and asked them to rank from 1 to 10. Data were descriptively and analytically (using Spearman correlation test) analyzed by SPSS software.
Results: Subject experts’ relevance score in Persian was lower in ISC than SID and higher than Google Scholar. The most subject relevant records were in the third score of system relevance. The records with the lowest system relevance score also had the lowest subject experts’ relevance score. SID in Persian had a strong and positive relation between the both scores but there was no relation in ISC. The highest matching level of the both scores was seen in SID in both languages on the both periods which means more likely to retrieve relevant records.
Conclusion: There is a similar retrieval pattern in both languages with subject expert’s view in SID showing the highest precision which was the lowest in Google scholar in Persian
