To satisfy quality attributes, architectural tactics are used. An architectural tactic determines how to implement a quality attribute in architectural styles. The interaction between architectural tactics and architectural styles plays an important role in meeting quality attributes. In this article, the interaction between architectural tactics, namely “availability” and “performance”, and architectural styles, namely “pipe & filter”, “layered”, “blackboard”, “client-server” and “broker” is evaluated, and then, a new ranking scheme for the architectural styles is proposed. Through this scheme, the best architectural style maybe obtained for every individual quality attribute or their combinations.https://jcomsec.ui.ac.ir/article_21852_92ba8d6a76d44b3153a1e394004563ef.pdfUniversity of Isfahan & Iranian Society of CryptologyJournal of Computing and Security2322-44601220140401Evaluating Behavioral Intentions of Tourists in e-Tourism9510921854ENFahimehParsaeiLecturer of Azad UniversityMehranRezaeiProfessor of Isfahan UniversityMonirehArabjafariJournal Article20131130Tourism is one of the major sources of income for many countries and with the advent of internet, using this new channel (internet) for providing different services of tourism, i.e., e-tourism, is growing rapidly. This is also the case in Iran, but it is clear that focusing on technology alone can’t lead the business to success. The key point of successful business in e-tourism is to concentrate on the customers and their behavior for having a better relationship with them. This study is intended to develop a model based on Decomposed Theory of Planned Behavior (DTPB) that considers influential factors to predict and evaluate intention of tourists and travelers while using e-tourism services and websites, such as www.expedia.com and www.priceline.com. The influential factors are studied and investigated through a survey with 259 responses. Structural Equation Modeling (SEM) has also been utilized for testing relevant hypotheses to either include or thwart specific factors which drive people to use e-tourism services provided in e-tourism websites. The results show that “Subjective Norm” and “Perceived Behavioral Control” significantly affect Iranian customer’s intention to use e-tourism (i.e., the websites which offer tourism services). In this research we not only worked on evaluating a model and the relationship between constructs, but also tried to find specific factors that drive people to use e-tourism. So, besides DTPB factors, we found that Curiosity has more effect on tourist intention. The findings have implications for Iranian tourism companies to predict the behavior of tourists when they are using the e-tourism, and also develop the CRM methods in e-tourism websites.https://jcomsec.ui.ac.ir/article_21854_86fc9b4c6039633a181e25fea90716ce.pdfUniversity of Isfahan & Iranian Society of CryptologyJournal of Computing and Security2322-44601220140401A New Hybrid Approach for Modeling Accurate Fuzzy Rule Based Classification Systems11112221855ENFahimehFarahbodMaster studen in Shahid Bahonar University of KermanMahdiEftekhariJournal Article20130104we propose in this article a new hybrid method for modeling accurate fuzzy rule based classication systems. The new method is a combination of manifold based data mapping method, a heuristic fuzzy rule based construction method and an evolutionary based rule weighting approach. Manifold based data mapping method considers the intricate geometric relationships that may exist among the data and computes a new representation of data that optimally preserves local neighborhood information in a certain sense. Although this new representation does not secure the interpret ability of obtained fuzzy models, the main intention of this research is to improve the classication accuracy signicantly. Experiments on some well-known datasets are performed to show the performance of the new proposed approach. Some nonparametric statistical tests are used to analysis the results obtained in experiments. Experimental results conrm the eectiveness of our proposed method in improvement of the classication accuracy.https://jcomsec.ui.ac.ir/article_21855_264262b0ff7d9bdd9e4d37b4f3a2bf99.pdfUniversity of Isfahan & Iranian Society of CryptologyJournal of Computing and Security2322-44601220140401Word Sense Disambiguation Based on Lexical and Semantic Features Using Naive Bayes Classifier12313221856ENAmir HosseinRasekhShiraz UniversityMohammad HadiSadreddiniComputer

Science and Engineering Department, Shiraz, Iran.Journal Article20130128Machine translation is considered as a branch of machine intelligence with about fifty years background. Ambiguity of language is the most problematic issue in machine translation systems, which may lead to unclear or wrong translation. One of the problems involved in natural language processing is the semantic and structural ambiguity of the words. The objective of this paper to focused on the word sense disambiguation. In here, the existing algorithms for word sense disambiguation are evaluated and a method which is proposed based on the concept, structure and meaning of the words. The experimental results are promising and indicate that this proposed approach significantly outperform its counterparts in terms of disambiguation accuracy.https://jcomsec.ui.ac.ir/article_21856_a6ee443bc566f1f441ca12068ea1f020.pdfUniversity of Isfahan & Iranian Society of CryptologyJournal of Computing and Security2322-44601220140401MRAR: Mining Multi-Relation Association Rules13315821857ENRezaRamezaniDepartment of Computer Engineering, Ferdowsi University of MashhadMohamadSaraeeElectrical & Computer Engineering, Isfahan University of Technology, Iran.Mohammad AliNematbakhshDepartment of Computer Engineering, University of Isfahan, IranJournal Article20131223In this paper, we introduce a new class of association rules (ARs) named"Multi-Relation Association Rules" which in contrast to primitive ARs (thatare usually extracted from multi-relational databases), each rule item consistsof one entity and several relations. These relations indicate indirect relationshipbetween entities. Consider the following Multi-Relation Association Rule wherethe first item consists of three relations live in, nearby and humid: "Those wholive in a place which is near by a city with humid climate type and also areyounger than 20 → their health condition is good". A new algorithm calledMRAR is proposed to extract such rules from directed graphs with labelededges which are constructed from RDBMSs or semantic web data. Also, thequestion "how to convert RDBMS data or semantic web data to a directed graphwith labeled edges?" is answered. In order to evaluate the proposed algorithm,some experiments are performed on a sample dataset and also a real-world drugsemantic web dataset. Obtained results confirm the ability of the proposedalgorithm in mining Multi-Relation Association Rules.https://jcomsec.ui.ac.ir/article_21857_da59f278d01b06f8cb72ae79ad0436d7.pdfUniversity of Isfahan & Iranian Society of CryptologyJournal of Computing and Security2322-44601220140401Solution of the Generalized Interval Linear Programming Problems: Pessimistic and Optimistic Approaches15916721858ENMehdiGhateeAmirkabir University of TechnologyJournal Article20121226This paper deals with linear programming problem with interval numbers as coefficients to exhibit with uncertainty. Since, the set of common intervals is not a field, we define generalized interval numbers to produce an algebraic interval field and on this field, we propose principle of uncertainty traverse instead of extension principle which permits to define operators on intervals exactly similar to the same operators on real numbers. In addition, we apply a total order on this field to transform interval linear programming into a traditional problem. The proposed order can be extended either pessimistically or optimistically. The numerical experiments are given to demonstrate the efficiency of the proposed scheme in comparison with the previous established works. The approach in this paper can be generalized to fuzzy linear programming problems taking the fuzzy cuts into account.https://jcomsec.ui.ac.ir/article_21858_d6dcdce12092a29d3652272f61c74264.pdf
