Among the reasons for this failure are some deficiencies in terms of methodology in inappropriate recognition and translation of KM dimensions and lack of systematic approach in establishment of causal relationships among KM factors. This article attempts to design an Organizational Knowledge Management Excellence Model. To design an organizational knowledge management excellence model based on library researches, interviews with experts and interpretive-structural modeling (ISM) was used in order to identify and determine the relationships between the factors of km excellence. Accordingly, 9 key criteria of KM Excellence as well as 29 sub-criteria were extracted and the relationships and sequence of factors were defined and developed in 5 levels for designing an organizational KM excellence Model. Finally, the concepts were applied in Defense Organizations to illustrate the proposed methodology.Faculty of Management, University of TehranJournal of Information Technology Management2980-79726320140923The Role of Knowledge Management in E-Business Strategyبررسی نقش مدیریت دانش در تدوین استراتژی کسبوکار الکترونیک3753945159310.22059/jitm.2014.51593ENAliKhaloueiAli AsgharPourezatMahdiShamizanjaniJournal Article20131105The purpose of this research is to study the role of knowledge management in building an E-business strategy.

These factors can be divided into two categories: internal and external. The internal factors show the characteristics of domestic firms that will shape their behavior, while the external factors represent the business environment of firms and include e-commerce infrastructure and supportive agents, governmental, legal and cultural factors and social factors. In this paper, the role of internal and external factors in the use of e-commerce tools in textile and clothing enterprises of Isfahan was discussed using factor analysis technique and correlation coefficients. Field survey results indicate that internal factors (prospective and strategic management, business size, flexibility, performance and expected performance) have the greatest impact on the use of e- commerce tools. Afterwards, the appropriate supporting factors (availability of skilled work force and ease of use) and favorable social and cultural factors make greater use of e-commerce tools possible for textile and clothing companies in Isfahan.Faculty of Management, University of TehranJournal of Information Technology Management2980-79726320140923Segmentation of Internet Banking Users Based on Expectations: A Data Mining Approachبخش بندی کاربران بانکداری اینترنتی بر مبنای انتظارات: رویکرد دادهکاوی4194345183610.22059/jitm.2014.51836ENShahriarAziziVahidHossein AbadiMohammadBalaghi InanlouJournal Article20131210In recent years,Internet-based banking services have become the focus of competition in Iran’s banking system.

This investigation aims at measuring the realization of above-mentioned goal by investigating into municipality portals, since the typical view of an e-city and the user interface between management processes of an e-city and citizens is a portal that all city services will be available through. A multi Case study using structured observation is the method used for the current investigation. Municipality portal services of five most populated cities in Iran including Tehran, Mashhad, Isfahan, Shiraz and Ahvaz were investigated, and then they were compared with municipality portal services of four none-Iranian municipality portals. According to the results of the present research, less than 50 percent and 60 percent of the world e-city services were found to be offered in Iranian municipality and none-Iranian municipality portals, respectively. The results obtained from the current investigation would have some suggestions for improvement of Iranian municipality portals.Faculty of Management, University of TehranJournal of Information Technology Management2980-79726320140923Presenting a New Method for Link Prediction in Social Networksارائه روشی جدید برای پیشگویی پیوند بین رأس های موجود در شبکه های اجتماعی4754865093610.22059/jitm.2014.50936ENAzamKeypourMortezaBarariHosseinShiraziJournal Article20131116Today, online social networks are very popular due to the possibility of creating relationships between people all over the world. These social networks with possibilities such as friend recommendation generally use local features derived from social graph structure. For friend recommendation, there are different algorithms with local and global approaches. In this paper, we proposed an algorithm with local approach that has a suitable performance compared to other algorithms. In addition, it has an acceptable speed, because of its being local. This new feature was examined on two large social networks: Epinions and Facebook. The research showed that this algorithm can present good predictions and acceptable recommendations.Faculty of Management, University of TehranJournal of Information Technology Management2980-79726320140923Investigating the Indicators Affecting the Success of Modern Banking Services Strategies from the View Point of Managers and Experts of Ansar Bankبررسی شاخصهای تأثیرگذار بر موفقیت راهکارهای خدمات بانکداری نوین از دید مدیران و نخبگان بانک انصار4875045093710.22059/jitm.2014.50937ENAlirezaNaderiYaserGhasemi NezhadJournal Article20130930With increasing development of information technology, first level banks are searching for suitable strategies to fulfill their customers' needs.
