Knowledge Retrieval and Semantic Systems

Abstract Introduction
Today, the insurance industry plays a significant role in the prosperity of the economy, so paying attention to the creation of knowledge can play a significant role in increasing the penetration rate of insurance. Therefore, the main question of the current research is how to design and explain the model of the elements of customer knowledge co-creation in the insurance industry? In order to answer this question, the present research aims to identify the elements of the customer knowledge co-creation model in the insurance industry in the first stage, and in the next stage to test the relationship model of the elements of customer knowledge co-creation in the insurance industry, and based on the results of Data analysis will provide solutions to the managers of this industry in order to make decisions and policies related to knowledge creation and as a result promote and improve insurance products and services and increase the penetration rate of insurance in the society.

Literature Review
 Knowledge Co-Creation
Knowledge Co-Creation has been described as an act of collective creativity, with applications ranging from product and service design to more abstract spheres of value creation taking place between two or more individuals who may or may not belong to the same actor group (Amann & Rubinelli, 2017). “Customer knowledge Co-creation is defined as the collective ability of group members to analyze, interpret, reconfigure customer-related knowledge, and it means that knowledge is co-created by group members” (Menguc et al., 2013). In the following, we discuss some of the researches conducted in the field of customer knowledge co-creation.
Itani et al. (2022) conducted a study with the aim of investigating the effects of using social media and customer relationship management technology on the customer knowledge co-creation and sales performance in B2B companies. Based on the theories of task-technology fit and self-determination, the findings show that social media, customer relationship management technology, and their interaction, support salespeople in joint value-creation efforts through the mediating role of knowledge enriched by these tools. The results indicated a significant moderating effect of the salesperson's job independence and the ease of the sales quota in increasing the relationship between knowledge and value co-creation.
Xie et al. (2020), in a study titled "Using Customer Knowledge for Service Innovation in Travel Agency Industry", investigated the influencing factors and the effects of service team access and the combination of customer knowledge on tourist service companies. The results showed that both factors of customer orientation and intensity of interaction are effective on customer knowledge co-creation teams, which can promote service innovation. Also, the results indicated that customer knowledge co-creation moderates the relationship between interaction intensity and service innovation.

Methodology
The current research was done in two stages using a mixed method. In this research, in order to identify the components of the customer knowledge co-creation model, first the qualitative approach of grounded theory was used. For this purpose, semi-structured interviews were conducted with a selection of insurance industry experts, including a number of university professors and insurance company managers, as a result of which the components of the research and their dimensions were identified. Then, in order to present the relationship model of the main components of the research, the opinions of experts were evaluated through the matrix of pairwise comparisons, and based on this, the conceptual model of the research was explained. Then, in order to test the research model and hypotheses, the partial least squares quantitative method was used. The statistical population in the quantitative stage consists of managers and experts of three active insurance companies in Iran, including Alborz, Iran, and Asia. The statistical sample was obtained from the random cluster sampling method, based on which 310 people were selected as a statistical sample. The data collection tool in the quantitative stage is a researcher-made questionnaire. Cronbach's alpha method was used to check the reliability of the measurement tool, and its value was greater than 0.7 for all variables. Therefore, all variables were confirmed in terms of reliability.

Results
In the first stage of the current research, the qualitative method of grounded theory was used to identify the components and dimensions of customer knowledge co-creation. As a result of this stage, 7 main aspects were identified for customer knowledge co-creation. After identifying the research components and developing the model, 9 hypotheses were formulated in the quantitative stage. Based on the findings of data analysis using the partial least squares method, all 9 research hypotheses were confirmed. The results showed that the infrastructure of information and communication technology has an effect on being knowledge-oriented. Also, being knowledge-oriented has an impact on internal marketing and customer relationship management. In addition, the effect of internal marketing and customer relationship management on customer orientation was confirmed. Also, the effect of customer orientation on creating motivation and trust building was confirmed, and finally, the effect of creating motivation and trust building on customer knowledge co-creation was confirmed.

Discussion
Customer knowledge co-creation is a process by which organizations acquire competencies and knowledge of customers, so that they can use this information to create an experience for customers and reach new markets for themselves.

Conclusion
According to the confirmation of all 9 research hypotheses and with emphasis on the structures (sub-indices) that have the highest factor load obtained from the partial least squares method, the following practical suggestions are presented:
In order to develop the component of “information and communication technology infrastructures” in insurance companies, considering the importance of "the company's presence in social media and producing up-to-date content", it is suggested that managers of insurance companies use experts who have enough expertise in the field of content production to manage social media pages. Also, through social pages, they can establish a two-way relationship with customers, especially special customers, and encourage them to share their insurance knowledge and experiences.
In line with the development of “internal marketing”, the managers of insurance companies should continuously strive to hold brainstorming sessions with the employees in order to update their knowledge and skills. In these meetings, in addition to presenting technical matters such as informing about possible changes in insurance policies, new insurance laws, etc., experts in fields such as marketing, psychology, and negotiation can also be invited so that the employees and the sales network, in addition to mastering the technical skills, also master the communication skills of the day.
In order to ensure customer satisfaction and as a result of complying with customer-oriented principles, insurance companies must first observe and understand the needs of their customers. For this purpose, they should listen to the expectations and criticisms of the customers, and by establishing a friendly relationship with them, in addition to getting to know the customers more and knowing their level of satisfaction, they should have a positive effect on their perception.
In order to increase the “trust of customers”, insurance companies should adopt strategies that lead to improving the mental image of customers towards the company's brand. Since the main mission of insurance companies is to issue perfect insurance policies as well as timely and adequate payment of damages, if this is done correctly, it can play an effective role in attracting customers’ trust.
Finally, in order to develop the customers' knowledge co-creation, insurance companies should use the experiences and knowledge gained from customers to produce and create new knowledge and improve and develop the organization's products and services.

Abstract The present study is going to evaluate the relation between knowledge management processes and job performance of employees in university of Tehran. The research’s sample includes 105 employees of Tehran university (21 men and 84 women) using the random sampling and applying the Cochran formula. Besides, research’s data was gathered through performance appraisal checklist and knowledge management questionnaire. The analysis of information was done by using statistical methods (T -test, Anova , U Whitney, mean and Pearson correlation coefficient). The findings of the study showed that the status of knowledge management among employees is lower than the supposed mean and that the job performance is above average. Evaluation of knowledge management and job performance among demographic variables: gender, age, educational level and history of serving demonstrated that only the age with knowledge management and also age, sex with job performance showed a significant difference. The results of the correlation coefficient between the components of the knowledge management and those of job performance indicated that the only significant correlation was found between the components of knowledge acquisition and the components of job performance (task and context performance) and among other variables no significant correlation was discovered.

Abstract Purpose: The purpose of this research is to investigate the role of data mining on the organizational performance of Tehran University's library directors with the knowledge management approach.
Methodology: The research method is a survey-analytical one that uses inferential statistics and structural equations for data analysis. The instrument of research is the Deravi Thesis Questionnaire (1394); for analyzing the data, the software S.P.S.S. and AMOS have been used. The research community includes the directors of the central library and satellite libraries of the state universities of Tehran. In total, 213 central and satellite libraries and the same number of managers are identified and based on the Cochran formula the sample consists of 137 managers. Since the distribution of data is normal, the parametric test of single sampled/grouped T-test is used to examine the first three hypotheses (knowledge management status, organizational performance, and data mining utilization). The hypotheses of the conceptual model of research are also analyzed based on structural equations.
Results: The findings of the study indicate that only one hypothesis (knowledge management status was confirmed of the six. Two other hypotheses, Organizational performance status and data mining utilization status were not accepted. None of the hypotheses related to the conceptual model of research (The effect of data mining utilization on knowledge management, the effect of data mining on organizational performance and the effect of knowledge management on organizational performance),  which were the main hypotheses of the research, were not confirmed.
Conclusion: The results of this study showed that the status of data mining utilization and organizational performance of the managers of the libraries of Tehran's public universities is moderate and the knowledge management status is desirable. The use of data mining and knowledge management does not affect the organizational performance of the directors of public libraries in Tehran's public universities. The data mining utilization is also ineffective on knowledge management from the perspective of the director of these libraries.
Originality / value: The originality and value of this research stems from the fact that so far, there has been done no similar study conducted in libraries which have studied the three data mining, knowledge management, and organizational performance variables.

Abstract Abstract Objective: The aim of this study was to determine the relationship between the ability to acquire knowledge of librarians in Kermanshah Academic libraries and their organizational growth and development. Methodology: The present study is a descriptive-correlational and has been conducted through a survey method. The statistical population of all librarians of Kermanshah Academic libraries was 58 people. Since the research community was limited and available, census method was used to collect data, then 55 questionnaires were completed and analyzed. A standard organizational development questionnaire and a researcher-made Knowledge Acquisition Knowledge Questionnaire were used for collecting data in five options based on Likert spectrum. Findings: The findings showed that the ability to acquire knowledge and its components (knowledge extraction, knowledge conversion and transfer of knowledge) among librarians of Academic libraries of Kermanshah is relatively favorable. The highest mean belonged to “knowledge extraction ability” (3.68) and the least frequency were related to the “ability to transfer knowledge” (3.25). Also, the average growth and organizational development and its components (rewards, relationships, structure, management, beneficial mechanisms, attitude toward change and goal) in Kermanshah Academic libraries were at the optimal level. In this section, the most frequency was related to “relationship” component and the lowest one was on “reward” item. Conclusion: The level of knowledge transfer ability among librarians was lower than other components of knowledge acquisition. The need to train and provide conditions for improving this skill and the spirit of knowledge sharing among librarians seems to be necessary. Because the ability to transfer and share knowledge, which is one of the main attributes of the knowledge acquisition cycle, is inevitable and necessary for librarians as disseminators of information. Therefore, the more employees improve their skills and thus have better performance, the most they will play effective role in improving the status, progress and development of their organization.

Abstract Data mining detects patterns in the massive volume of data used in many disciplines. It can also be useful in our field, especially in information retrieval. In information retrieval, first the system-oriented paradigm and then the user-oriented paradigm have been introduced, the second paradigm being concerned with information needs. In the second paradigm, the inclusion of inappropriate queries is considered the main reason for not retrieving relevant documents. Therefore, one of the main topics of this paradigm is proposing and extending the appropriate query in the recommender system that can be used for data mining methods. There are four important methods to propose a query to strengthen the recommender system. The time series rule is one of these methods that deal with query frequency in a particular time unit. Another method is the association rule that addresses the dependency and association of queries. In addition to the dependence and association of queries, the order of query terms is also considered in the method of Association rule with Levenshtein distances. However, in all three of these methods, the log file is used, while in probabilistic theory, the document words are used to repair the lexical gap between the queries and the documents. Therefore, it seems that using probability theory to suggest the query yields better results.

Abstract The main purpose of research is to determine the relationship between organizational commitment and the tendency to share knowledge among the staff of public libraries in Khuzestan province.This research was applied and using descriptive-correlational method. The statistical population of this research was all staff of public libraries. Simple sampling method has been used to determine the sample size, of which 215 were selected as statistical sample. The data were gathered using questionnaires and analyzed using the software SPSS.21.The results of the study showed that organizational commitment (mean = 78.44) and its dimensions are higher than average. Also, knowledge sharing (104 = 28/28) and its dimensions are higher than average. Meanwhile, there is a significant relationship between organizational commitment and employees' tendency to share knowledge in public libraries of Khuzestan province (sig = 0/001 = 0 / r = 0/688). Regarding the moderating role of descriptive statistics on the relationship between organizational commitment and knowledge sharing, it was found that only education corrected the relationship between organizational commitment and knowledge sharing, and the rest of the variables did not modify this relationship. The consequence is that the more these conditions become, the greater the sense of belonging to the organization and individuals will tend to share their knowledge, experiences and skills with other members of the organization.

Abstract In present paper social media archiving software were studied.  In this study, data gathering was done through documentary study and analytical survey.  To evaluate whether or not each software capability was used, the CIR method, the exploratory factor load, and the confirmatory factor load were used; the acceptance of each capability was assessed by a median (mid-range criterion 3). Then, each item was ranked based on the mean of the Friedman test. In the second stage, the CIR of each capability, and in the last stage, the confirmatory factor and the exploratory factor load. Research questions were analyzed using one-sample t-test. Advanced archive search capabilities, "archive categorization (easy browsing)" and "visual reporting" are the most important software requirements for experts.
