The development of indoor Location-Based Services faces various challenges that one of which is the method of generating indoor routing graph. Due to the weaknesses of purely geometric methods for generating indoor routing graphs, a semantic-geometric method is proposed to cover the existing gaps in combining the semantic and geometric methods in this study. The proposed method uses the CityGML...
تحقیق حاضر کوششی بود در جهت (الف) مشخص نمودن استراتژیهایی که دانشجویان و دانش آموزان ایرانی برای یادگیری زبان انگلیسی بطور عام و یادگیری واژگان بطور خاص مورد استفاده قرار می دهند، (ب) پیدا کردن ارتباط معنادار مابین استراتژیهای یادگیری زبان انگلیسی و واژگان انگلیسی از یک طرف و سطح توانایی زبانی فراگیران از طرف دیگر. (ج) پی بردن به تغییرات معناداری که بواسطه سن، جنس ، قومیت ، سالهای یادگیری زبان ...
Introduction: Students’ academic achievement has always been a concern of education authorities. One of factors in academic achievement is attention to effective components on the learning, including learning strategies. Thus, the present research was done to determine the relation between cognitive and meta-cognitive learning strategies and academic achievement in medical surgical nursing cour...
the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...
this study investigates the strategies native english and persian speakers employ for expressing gratitude in different situations. the strategies of persian efl learners are also compared with english strategies in order to find the differences that may exist between these two languages. social status and size of imposition of the favor are social variables which are investigated in detail for...
Semantic query optimization uses semantic knowledge in databases (represented in the form of integrity constraints) to rewrite queries and logic programs to achieve eecient query evaluation. Much work has been done to develop various techniques for optimization. Most of it, however, is applicable to top-down query evaluation strategies. Moreover, little attention has been paid to the cost of th...
This paper investigates the impact of geometric semantic crossover operators in a wide range of symbolic regression problems. First, it analyses the impact of using Manhattan and Euclidean distance geometric semantic crossovers in the learning process. Then, it proposes two strategies to numerically optimize the crossover mask based on mathematical properties of these operators, instead of simp...
Despite expectations being high, the industrial take-up of Semantic Web technologies in developing services and applications has been slower than expected. One of the main reasons is that many legacy systems have been developed without considering the potential of the Web in integrating services and sharing resources. Without a systematic methodology and proper tool support, the migration from ...
This paper describes a general architecture SCAN for hybrid symbolic connectionist processing of natural language phrases. SCAN's architecture shows how learned connectionist domain-dependent semantic representations can be combined with encoded symbolic syntactic representations. Within this general architecture we focus on a connectionist model for semantic classiication based on a scanning u...
