Constructing a web recommender system using web usage mining and user’s profiles
, Pages: 2479-2486 T. Mombeini, A. Harounabadi and J. Rezaeian Sheshdeh PDF (288 K) |
Abstract: The World Wide Web is a great source of information, which is nowadays being widely used due to the availability of useful information changing, dynamically. However, the large number of webpages often confuses many users and it is hard for them to find information on their interests. Therefore, it is necessary to provide a system capable of guiding users towards their desired choices and services. Recommender systems search among a large collection of user interests and recommend those, which are likely to be favored the most by the user. Web usage mining was designed to function on web server records, which are included in user search results. Therefore, recommender servers use the web usage mining technique to predict users’ browsing patterns and recommend those patterns in the form of a suggestion list. In this article, a recommender system based on web usage mining phases (online and offline) was proposed. In the offline phase, the first step is to analyze user access records to identify user sessions. Next, user profiles are built using data from server records based on the frequency of access to pages, the time spent by the user on each page and the date of page view. Date is of importance since it is more possible for users to request new pages more than old ones and old pages are less probable to be viewed, as users mostly look for new information. Following the creation of user profiles, users are categorized in clusters using the Fuzzy C-means clustering algorithm and S(c) criterion based on their similarities. In the online phase, a neural network is offered to identify the suggested model while online suggestions are generated using the suggestion module for the active user. Search engines analyze suggestion lists based on rate of user interest in pages and page rank and finally suggest appropriate pages to the active user. Experiments show that the proposed method of predicting user recent requested pages has more accuracy and cover than other methods.

New jitter-aware network coding approach for packet selection in wireless mesh network using Jacobsen algorithm
, Pages: 2487-2494 Rasoul Nikoee Saravani Seyed Javad Mirabedini PDF (288 K) |
Abstract: Network coding (NC) is an approach for increasing the throughput of communication networks. NC has been derived from the idea of combining packets and forwarding them to achieve higher throughputs. From the very beginning, NC has attracted the attentions of scholars since they could improve the throughput of wired networks. Previous works have focused on the improvement of network throughput. Some methods add artificial delay to send packets. The methods are used in order to gain coding time and to increase throughput but they could not be used in immediate applications. However, early packets dispatch or adding delay to packets, for increasing coding time, can influence on the jitter of sent data. On the other hand, jitter is an important parameter in determining multimedia broadcasting time. Unlike previous methods, this paper provides a jitter-based coding algorithm using Jacobsen method. In the proposed method, the selection priority is based on packets jitter so that a packet with the minimum jitter is considered as the first priority for coding. Related computations are performed through Jacobson algorithm. According to simulation results, selecting a proper coding pattern for jitter can improve jitter by 30% while the throughput of this method shows no considerable change compared with that of available methods.

Delay-based network coding packet selection
, Pages: 2509-2516 Rasoul Nikoee Saravani and Javad Mirabedini PDF (288 K) |
Abstract: Network coding is introduced as a technique to improve performance in communication networks. In network coding, intermediate nodes mix packets to enhance network performance. To increase throughput, several approaches have been proposed based on network coding. Many approaches use delay in sending packets to increase throughput. These approaches are not suitable for delay sensitive applications. To solve this problem, some methods make a tradeoff between delay and throughput. In this paper, unlike other approaches, network coding is used to reduce end-to-end delay in wireless networks. In our proposed approach, packets do not receive more delay and the priority of the selected packets for coding is based on their end-to-end delay. The packet that tolerates more delay has higher priority for coding with forwarding packet. Simulation results illustrate that using network coding compared with other approaches can reduce end-to-end delay. DOI: 10.5267/j.msl.2014.11.006 Keywords: Coding Opportunity, QoS, Network Coding |

, Pages: 2537-2554 Mostafa Jafari and Fatemeh Rezaee PDF (288 K) |
Abstract: Nowadays, it is important to achieve and to sustain an organization’s competitive advantage in complex environments. This paper evaluates different concepts that have led to such benefits. The study sheds light on resource based view (RBV) and its role to reach sustainable competitive advantage (SCA) within banking industry of Iran. A valid research instrument was utilized to conduct a survey of 150 top- and middle-level managers from Mellat bank of Iran. With a response rate of 81.3 percent, 122 questionnaires were returned while a number of valid and usable questionnaires were 101. In order to determine validity of questionnaire, the content validity and Cronbach's alpha were used to determine the reliability of the questionnaire (RBV questionnaire 0.934, SCA questionnaire 0.843). The study utilized structural equation modelling, and a series of exploratory and confirmatory factor analyses and they tested the integrated model of MKM and SCA. Statistical support was found for the hypothesized relationships. Moreover it has been shown that RBV had the greatest effect on the market centered SCA, while it had the least influence on the financial centered. The findings offer valuable insights on the generalizability of MKM in a research setting. Structural equation modeling has been implemented and the study also used freedman test to rank the factors and the results show that communication was the most important factor (4.41), followed by process (4.03), knowledge implementation (2.79), decision making (2.54) and human resources (1.22) was the last important factor.

, Pages: 2555-2570 Katayoun Taghizadeh, Eskandar Mokhtari and M.H. Mahmoudi Sari PDF (288 K) |
Abstract: The aim of this investigation is to establish an applicable model for knowledge management implementation that works suitably in organizations involved in projects defined for a historic building such as restoration. Based on a peer review on general approaches in literature, some main improvement potentials are recognized to enable the model to meet with the especial objectives, which shall be considered in such projects. Content analysis was applied to ascertain the new presented model capabilities and improvement in each of three main core components of knowledge management implementation model including peoples, processes, and technologies. We came up with a new conceptual model named as Finger Frame Model with four individual tiers connected with an intelligent communication medium. It is concluded that three main components of KM block diagrams consist of knowledge identification, acquisition, and prevention are appropriately covered in basic tier. The other three components of inner cycle of KM basic diagram consist of using, development, and distribution are also covered in an interface between operators and basic tiers, which together with make lower frame of new presented model. The model is in a continuous improving stage considering self-monitoring processes in an individual tier with the same name, which is located in the upper frame. An upper layer named as goal tier is also located in top frame in which, the main quantitative goals of KM implementation in the project organization are considered. The conceptual diagrams as well as internal processes of each main tier are also presented and discussed. Based on the overall explanations, some main benefits and risks are highlighted for new presented model and outlooks are debated. The model is applied in a real case study and the results are compared with the previous knowledge management implementation model. The results show that the model works efficiently in projects organization related to the historic building restoration.
