Learning to rank refers to machine learning techniques for training a model in a ranking task. Learning to rank has been shown to be useful in many applications of information retrieval, natural language processing, and data mining. Learning to rank can be described by two systems: a learning system and a ranking system. The learning system takes training data as input and constructs a ranking model. The ranking system then makes use of the learned ranking model for ranking prediction. In this paper, a new learning algorithm based on ensemble learning for learning ranking models in information retrieval is proposed. This algorithm iteratively constructs weak learners using a fraction of the training data whose weight distribution is determined based on previous weak learners. The proposed algorithm combines the weak rankers to achieve the final ranking model. This algorithm constructs a ranking model on a fraction of the training data to increase the accuracy and reduce the learning time. Experimental results based on Letor.3 benchmark dataset shows that the proposed algorithm significantly outperforms other ensemble learning algorithms. Manuscript profile

Nowadays one of the biggest problems of IT organizations in less developed countries is paying too much attention to infrastructure and technology of organizations. This is due to the point that many managers in organizations believe that existence of IT infrastructure and technology by itself is a sign of maturity of an organization. Although technical facilities and infrastructure such as networks, hardware, software etc., is essential for providing appropriate services and optimal performance, but these features cannot provide a competitive advantage and increase the maturity of the organization. The missing link in these organizations, which have been less considered, is how to use these features to achieve organizational goals. In different areas, there are several standards and optimal methods for defining and optimizing processes. Some of the most complex models which should be considered in different units of information technology are, models and frameworks related to IT governance. IT governance focuses on implementation and management of quality of IT services so as to meet business needs. IT governance is done by service providers through an appropriate combination of people, process and information technology. The purpose of this paper is to examine different models and frameworks of IT governance models, in order to propose a framework for assessing IT services Manuscript profile

Information and its protection is one of the most important pillars of survival of today's organizations. Defines and considers many ISMS implementation failures to be rooted in organizational issues and disregard for the organization's readiness prior to implementation. Therefore, assessing the situation and prioritizing information security risks and creating an overview and hierarchy of it, is important in the successful establishment of the information security system. However, in terms of dimensions, effects and various causes of security risks and considering the multiplicity of indicators and effective parameters of ISMS implementation, it is necessary to use multi-criteria decision-making models in their evaluation and ranking. . In this study, an attempt has been made to classify the factors affecting the information security management system into two groups of soft and hard factors and in order to accurately rank and focus more, especially in conditions of uncertainty that is inherent in human decision making, Fuzzy hierarchical analysis (FAHP) was performed. Based on this and with the help of a questionnaire to quantify the results, the opinions of technical experts including academic experts, managers and employees of the information technology department of social security branches in Guilan province have been used as a case study of this research. The results show that soft factors including managerial and cultural / social factors are more important than hard factors including financial and technical / technological factors in information security management system and management factors are more important than other soft factors as well as technical / technological factors. They are more important than other difficult factors. Manuscript profile

The strategic approach to project management is a new approach that has received more and more attention from business thinkers in the last decade. Having a strategic approach in the field of information technology projects requires managers to choose the right strategy in the first step of project management, taking into account several factors influencing the choice of strategy. Logical and adaptive approaches are the two dominant strategies in project management, each of which requires different tools, resources, and procedures. Despite the increase in investment in IT projects and the dependence of organizations on such technologies, still No study has been conducted to assist IT managers in choosing the appropriate strategy for such projects. Therefore, the main purpose of this study is to identify the approach of selecting the appropriate strategy in the management of information technology projects. In order to achieve this goal, in the first stage, in order to identify the factors influencing the choice of IT project management strategy, after a comprehensive review of the literature in the relevant field, the opinions of experts in the focus group have been used. In the second stage, in order to validate the extracted factors, and in the third stage, in order to weight each of the factors in selecting the two dominant logical and comparative approaches, experts are surveyed using the survey method. In the developed methodology, the factors that influence the choice of strategy are: process factors, human factors, system related factors and contextual factors.

Recent expansions of web demands for more capable information retrieval systems that more accurately address the users' information needs. Weighting the words and terms in documents plays an important role in any information retrieval system. Various methods for weighting the words are proposed, however, it is not straightforward to assert which one is more effective than the others. In this paper, we have proposed a method that calculates the weights of the terms in documents and queries as interval numbers. The interval numbers are derived by aggregating the crisp weights that are calculated by exploiting the existing weighting methods. The proposed method, calculates an interval number as the overall relevancy of each document with the given query. We have discussed three approaches for ranking the interval relevancy numbers. In the experiments we have conducted on Cranfield and Medline datasets, we have studied the effects of weight normalization, use of variations of term and document frequency and have shown that appropriate selection of basic term weighting methods in conjunction with their aggregation into an interval number would considerably improve the information retrieval performance. Through appropriate selection of basic weighting methods we have reached the MAP of 0.43323 and 0.54580 on the datasets, respectively. Obtained results show that he proposed method, outperforms the use of any single basic weighting method and other existing complicated weighting methods. Manuscript profile

Nowadays, investing in information and communication technology (ICT) is inevitable, because it affects various aspects of human life, including the economy. Due to the rapid growth of population, increasing energy demand, and limited energy resources, one of the basic measures to achieve sustainable development in countries, is optimization and reform of energy consumption structures. Given that the home sector is one of the main sectors of energy consumption, one of the effective approaches in reducing and managing household energy expenditures is to use ICT capabilities. In this regard, in this study, the effect of ICT expansion on energy consumption of urban households in Iran using the Panel Data method and GLS model during the period 2008-2015 and in the form of provincial data has been analyzed. The results indicate that in some models, a significant reducing effect of ICT on energy expenditure was observed. However, in most of the estimated models, there is no significant reducing effect of ICT on household energy expenditure. It seems that the main reasons for this are the subsidy structure governing energy prices, the low share of energy in total household consumption expenditures, the lack of proper consumption culture.

The increasing development of tools producing data in different services and the need to store the results of large-scale processing results produced from various activities in the national information network services and also the data produced by the private sector and social networks, has made the migration to new databases solutions with appropriate features inevitable. With the expansion and change in the size and composition of data and the formation of big data, traditional practices and patterns do not meet new requirements. Therefore, the necessity of using information storage systems in new and scalable formats and models has become necessary. In this paper, the basic structural dimensions and different functions of both traditional databases and modern storage systems are reviewed and a new technical solution for migrating from traditional databases to modern databases is presented. Also, the basic features regarding the connection of traditional and modern databases for storing and processing data obtained from the comprehensive services of the national information network are presented and the parameters and capabilities of databases in the standard and Hadoop context are examined. In addition, as a practical example, a solution for combining traditional and modern databases has been presented, evaluated and compared using the BSC method. Moreover, it is shown that in different data sets with different data volumes, a combined use of both traditional and modern databases can be the most efficient solution. Manuscript profile

In this article first the use of computer security models and its benefits are discussed in a novel way. Then, while briefly introducing the space of computer security encounters in the form of ontology, for the first time, three perspectives in the study of patterns in this field have been identified and distinguished from each other. These three perspectives include the view of secure models, the view of security models, and the view of the framework and system to security models. The first and third perspectives are briefly explained and the second perspective is studied in detail from the perspective of the organization of patterns, including the five types of organization. The five types mentioned include software-based lifecycle organization, logical-level organization-based organization, threat-based classification-based organization, attack-based classification-based organization, and application-based organization. In this type of introduction of patterns, the audience acquires a comprehensive view of the discourse of computer security patterns and acquires the necessary knowledge to make better use of these patterns. Finally, the analysis and idea of this research is presented in the form of introducing a new type of organization in order to facilitate the proper use and addressing of patterns. In this idea, it is stated that the existing categories are mostly static and forward-looking and do not have the necessary dynamism and backwardness, and the idea of covering all stakeholders and security ontology can have this feature and, in addition, include agile patterns as well. .

iThe purpose of this article is to identify and analyze the key drivers of digital signature implementation in Iran with a fuzzy Delphi approach. In terms of practical purpose and in terms of information gathering, the research has benefited from a hybrid approach. The statistical community consists of all experts and specialists in the field of information technology and digital signature and articles in this field. The sample size of the statistical community of experts is 13 people who were selected by the purposeful sampling method. 30 articles were selected based on their availability and downloadable, non-technical nature, and relevance to the topic. The method of data analysis was done according to the fuzzy Delphi approach. Validity and reliability were calculated and confirmed using the CVR index and Cohen's kappa test with coefficients of 0.83 and 0.93, respectively. The results prove that the key drivers of digital signature implementation in Iran include 5 main dimensions and 30 concepts, which are 1) security (information confidentiality, information security, sender authentication, document authentication, privacy protection, trust between parties), 2) business (digital business models, communication needs, staff management, organization size, organizational structure, organization resources, organizational culture, top managers, competition ecosystem, e-governance), 3) user (perceived convenience, perceived benefit, consumer behavior, consumer literacy, consumer lifestyle), 4) technical (development of technical infrastructure, systems integration, system complexity, system tanks, design quality, technical speed of certificate production and verification, impermeability of hackers) and 5) Legal (legal licenses, penal laws, legislative body, e-commerce laws).

Today, information and communication technology has influenced all areas of human life, including economics and politics. In research on the effects of information and communication technology, its effects on economic risk and political risk have not been considered so far. Therefore, this study has examined the effect of ICT development on economic and political risk for three selected groups of developed, developing, and OPEC countries in the period 2007- 2019. The panel data method was used to estimate the model. Based on the model estimation results for all sample countries, the deployment of information and communication technology reduces economic and political risk; But the results are different for each group. As the development of information and communication technology in selected OPEC members and developing countries increases economic risk; But in developed countries, it reduces economic risk. Also, in OPEC member countries, no significant relationship was found between ICT and political risk, and in selected developed and developing countries, ICT increases political risk.

Due to its power in modeling complex relations between entities, graph theory has been widely used in dealing with real-world problems. On the other hand, information retrieval has emerged as one of the major problems in the area of algorithms and computation. As graph-based information retrieval algorithms have shown to be efficient and effective, this paper aims to provide an analytical review of these algorithms and propose a categorization of them. Briefly speaking, graph-based information retrieval algorithms might be divided into three major classes: the first category includes those algorithms which use a graph representation of the corresponding dataset within the information retrieval process. The second category contains semantic retrieval algorithms which utilize the graph theory. The third category is associated with the application of the graph theory in the learning to rank problem. The set of reviewed research works is analyzed based on both the frequency as well as the publication time. As an interesting finding of this review is that the third category is a relatively hot research topic in which a limited number of recent research works are conducted. Manuscript profile

Social networks have become one of the most important decision-making factors in organizations due to the speed of publishing events and the large amount of information. For this reason, they are one of the most important factors in the decision-making process of information validity. The accuracy, reliability and value of the information are clarified by these networks. For this purpose, it is possible to check the validity of information with the features of these networks at the three levels of user, content and event. Checking the user level is the most reliable level in this field, because a valid user usually publishes valid content. Despite the importance of this topic and the various researches conducted in this field, important components in the process of evaluating the validity of social network information have received less attention. Hence, this research identifies, collects and examines the related components with the narrative method that it does on 30 important and original articles in this field. Usually, the articles in this field are comparable from three dimensions to the description of credit analysis approaches, content topic detection, feature selection methods. Therefore, these dimensions have been investigated and divided. In the end, an initial framework was presented focusing on evaluating the credibility of users as information sources. This article is a suitable guide for calculating the amount of credit of users in the decision-making process. Manuscript profile

The purpose of this research is to present the framework of the national plan for transparency and information release. The research employs an integrated approach (qualitative and quantitative) and grounded theory as its research methodology. In the qualitative part، with an in-depth and exploratory review of upstream laws and documents، models، theories، plans، and white papers of different countries related to transparency and information release، data analysis was done until theoretical saturation through three stages of open، axial، and selective coding. To acquire the dimensions، components، and subcomponents of this framework، 129 concepts were extracted from 620 primary codes، which were reduced to 593 secondary codes by removing the duplicated elements. Finally، 24 subcategories were placed under the five main components based on the paradigm model. In the quantitative section، the results of the analysis of the questionnaire indicated that، from a validity standpoint، the total value of the questionnaire، in different dimensions، was between 0.87 and 0.92، and the reliability coefficient was between 0.73 and 0.78. Based on data analysis، the establishment of a supranational management institution for transparency and information release، the precise determination of exceptions، network governance، demanding transparency، adherence to frameworks، maximum disclosure and support for legitimate disclosure، and the establishment of a data governance center are among the subcategories emphasized in this framework.

Generally, in performing technical projects, especially in the field of information and communication technology, the most important criterion for handing over the project is having technical capabilities, and less attention is paid to the communication skills of project managers, such as having emotional intelligence. Lack of attention to this issue seems to reduce the effectiveness of team communication and thus lead to project failure. The aim of this study was to measure the effect of emotional intelligence of project managers on the effectiveness of team communication in the projects of the Institute of Communication and Information Technology. The method of the present research is descriptive-analytical of correlation type, the statistical population of which consists of project managers and members of the project teams of the Research Institute of Communication and Information Technology. The statistical population includes 19 project teams that have been selected by census method. Data collection tools are Bar-On Emotional Intelligence Questionnaire and Senior Questionnaire to evaluate the effectiveness of project team communication. Pearson correlation coefficient, multivariate regression and imaginary variable regression and dependent t-test were used to analyze the data. The results show that the emotional intelligence of project managers affects effective communication in the project team. However, only interpersonal skills, interpersonal skills, and adaptability can predict effective communication within the project team, and the dimensions of general mood and stress management do not affect these relationships Manuscript profile
