 Designing metadata ontology model for semantic representation of Theses by using the SPAR (Semantic Publishing and Referencing) Ontologies. This study was an applied form and two methods were used, Content Analysis and mapping. The metadata of 69 theses and dissertations on the National Library and Archive of Iran in three Databases: 1) Digital Library of National Library and Archive of Iran. 2) Rasa Software and 3) Ganj in the Iranian Research Institute for Information Science and Technology were selected modified and completed by mapping. On the other hand, by analyzing the entities of each SPAR ontology and suggesting another entity to the researcher, the checklist was formed. This checklist included classes, properties, and individuals. At last, by entering them into Protégé software version 5.5, the model of metadata ontology, MdOntTDs, was drawn. Findings identified deficiencies in the existence of four important metadata elements (subject, supervisor, advisor, and abstract) in RASA and NLAI Digital Library. Among the 18 SPAR Ontologies, the most entities were selected from FaBiO, FRAPO, and CiTO respectively. All entities of BiDO, BiRO, C4O, Fivestar, FR, FRBR, PO, PRO, PSO, and PWO were suitable for theses. 195 individuals from 6 SPAR Ontologies, 292 individuals labeled with MdTDs from theses, and 100 individuals labeled with SUNMdTDs were selected by the researcher and entered into the software. 1558 entities categorized by class, Properties (object, data, and Annotation), and individuals along with the description and definition of each entity were placed in the software, in the form of hierarchical and determining axioms for classes. And specifying domain and range for relationships. Finally, the RDF graph was drawn using the OntoGraf plugin, and the final Model, MdOntTDs was developed. this research has proposed three new types of metadata: 1) Except for the existing keywords, topics have been categorized and modeled up to three levels including 4 main categories, 16 subcategories, and many units. Each of these final topics has been related to “hasSubject” and “isSubjectOf” properties. 2) The research methods of Theses that were connected with “hasMethod” and “used in” properties. 3) The papers taken from Theses were also searched, as far as possible, and were connected with “hasJournalArticle” and “journalArticleOf” properties. This model, if implemented, can overcome keyword search limitations, the problem of linking and Data sharing on the web, and the inconsistency of data. In the software, classes and their related individuals are visible in the form of a hierarchical network in RDF triples, and the connection between entities with increasing access points promises deeper semantic searches. However, due to the absence or lack of tagged and linked data, usage of the some of selected entities is not possible.

The purpose of this research is to investigate the interaction of Users (graduate students of Kharazmi University) with Ganj database in order to evaluate the performance of this database according to the honeycomb user experience Model. It is expected that the results of this study can help to solve the existing interactive difficulties while identifying the status of effective elements in the user experience in interacting with this database. This research is practical and was done by survey method. The research tool was a questionnaire that was designed using 7 components of the honeycomb: the usefulness, accessibility, usability, searchability, validity, desirability and value of the Iranian scientific database (Ganj). Analysis of research data were performed using descriptive and inferential statistics and SPSS software. Also we used Amos software to confirm the research model using path analysis method.  Findings showed that there was a great positive effect between accessibility and usability, usefulness and availability, desirability and credibility of the Ganj database; That is, with increasing the amount of accessibility variable, the amount of usability variable and with increasing the amount of utility variable, the amount of accessibility variable and vice versa increases. As a result, if the Ganj database is not accessible, the usability and usefulness of this database, which aims to publish information for researchers, as well as the usefulness of the services provided to researchers by this database will be reduced. As the desirability variable increases, the validity variable increases and vice versa. As a result, if students are dissatisfied with the features of desirability (appearance design, design capabilities of search components ...), their trust in the database will be lost and the credibility of the Ganj database in providing better services will be reduced. From the findings of this study, it can be concluded that the variable "value" as a strong and powerful variable has a direct and indirect positive effect on other research variables. This finding shows that if a database like Ganj does not create value for users, other components related to the user experience will not be in a good condition, and vice versa. Among these, the accessibility variable is also of special importance, which affects other variables in the Ganj database. As a result of not having access to the Ganj database, the usability of this database is reduced. If the capabilities of using the Ganj database are compromised, the credibility and usefulness of the Ganj will be reduced, and therefore users will lose their trust in this database, and the work with Ganj will not be satisfactory and useful for its users.

The main purpose of this study was to evaluate the Iran Scientific Information Database (Ganj) using user engagement scale.

This research is an applied one. A standard questionnaire for User Engagement Scale was used to collect the data, which is composed of four scales including Focused Attention, Perceived Usability, Aesthetic Appeal, and Reward. SPSS software was used for data analysis. The population of this study is the graduate students of Tabriz University, of which 50 students who declared their readiness to participate in the research was selected as sample.

Results showed that the Focused Attention scale has the lowest and the Perceived Usability scale has the highest average score in both systems. The mean scores for the Attention, Perceived Usability, Aesthetic Appeal, and the Reward were 2.28, 2.77, 2.31, and 2.57 in the previous version of Iran Scientific Information Database (Ganj), and were respectively 2.56, 2.91, 2.79, and 2.84 in the new platform of the same database.

Although new platform of ISID (Ganj) is relatively better than its previous version in term of UES, However, in order to improve the user engagement in the new platform, it is necessary to pay more attention to the principles of user interface design.
