چکیده: 

عامل های هوشمند به عنوان وسایل برجسته ای در راستای تحقق بخشیدن به نگرش وب معنایی در نظر گرفته می شوند. این عاملها با یکپارچه سازی آنتولوژ ها و قوانین در وب معنایی، می توانند با یکدیگر تعامل و همکاری داشته باشند، اما مشکل اساسی، نبود امکان استنتاج توزیع شده کارا برای یکپارچه سازی آنتولوژی ها و قوانین در چندین پایگاه دانش است. روش های ارائه شده برای استنتاج توزیع شده، اغلب بسیار زمانبر و حافظه بر بوده، به استنتاج کامل و دقیقی منجر نمی شوند. در این مقاله ما برای رفع این مشکل سیستم استنتاج توزیع شده ای را پیشنهاد می کنیم که بر اساس منطق Order-sorted به ارائه دانش می پردازد. طرح پیشنهادی برای استنتاج توزیع شده از انتشار صفات دائمی و غیردائمی معتبر بین پایگاه های دانش استفاده می کند. همچنین با در نظر گرفتن زمان و موقعیت صفات برای استنتاج، صفات غیردائمی معتبر بلا استفاده نمی مانند و از آنها در زمان و موقعیت معتبرشان برای استنتاج توزیع شده استفاده می شود. بنابراین، علاوه بر استنتاج کامل، دانش به دست آمده در پایگاه های دانش توزیع شده به طور کامل در نظر گرفته شده و استنتاج توزیع شده ای با کارایی بالا، دقیق و بدون از دست دادن دانش خواهیم داشت.

A B S T R A C T The current research is descriptive-analytical. In terms of purpose, it is in the category of applied research. Both library and field methods have collected the information required for this research. The statistical population of the research consisted of citizens living in Kasra, Azadi, Rezvan, Rahan, Hasht Behesht and Zeytoun residential complexes, which consisted of 6588 people, and the sample size according to the Cochran formula was 364. The study results of the studied residential complexes from the perspective of spatial connectivity indicators indicated that among the investigated complexes, Rahan residential complex had the lowest connectivity index compared to the rest of the complexes, and the highest share of this comparison goes to Kasra residential complex. From the comparison of the complexes based on the interconnection index, we conclude that the location of spaces and accesses in Rahan complex is very weak. Compared to the rest of the complexes, the location of access and communication in Kasra complex is lower. Moreover, Rezvan has been suitable and successful. It is said that the increase of connection in public spaces occurs with increase of sociability. Among the other results of this research, the spatial Order component with the path coefficient value of 0.368 has the highest path coefficient among the investigated components. In the first place, the playability component with a path coefficient of 0.253 is in the second place, the multi-purpose component with a path coefficient of 231 0.0 in the third place, the security component with a path coefficient of 0.162 is in the fourth place and the environmental comfort component is in the fifth place with a path coefficient of 0.153 Extended Abstract Introduction In the public space of neighborhoods and residential environments, the issue of sociability has been less addressed. Public spaces can boost the social life of citizens by strengthening social interactions and being involved in social sustainability. The residential environment conveys the residents a sense of well-being and satisfaction through physical, social or symbolic features. In each residential complex, according to the different arrangements of the blocks in it, it is possible to reach different influential indicators of the public space in it, which, according to the way they are arranged, have different potentials from the point of view of sociability in them. Declining sociability causes many problems in relationships between people and reduces the sense of belonging to a place, security, and other issues caused by not paying attention to the quality of collective life in housing. The main question is: - What are the components of the spatial structure affecting the sociability of residential complexes in the city of Kermanshah?   Methodology The current research is descriptive-analytical. In terms of purpose, it is in the category of applied research. Two library and field methods have collected the information needed for this research. In the field method, primary data collection has been done according to the research questions by designing a 5-scale Likert scale questionnaire. The statistical population of the study consisted of citizens living in Kasra, Azadi, Rezvan, Rahan, Hasht Behesht and Zeytoun residential complexes, which consisted of 6588 people, and the sample size was estimated to be 364 people using the Cochran formula. Factors such as the ease of access to the complexes, the willingness and cooperation of the residents and the management of the complexes were also influential in selecting the samples studied in this research. In this research, in Order to investigate the sociability of residential complexes based on the   theoretical framework prepared in the present research, the physical indicators affecting this issue include five indicators of "connectivity, interconnectedness, control, selection and depth" in each of The studied samples have been evaluated and analyzed in public spaces including the playground, gathering space, parking lot, and lobby. This research used Depthmap analytical software and structural equation modeling software to analyze the data.   Results and discussion In this research, the relation of sociability of public spaces of residential complexes in Kermanshah, which includes Kasra residential complex, Azadi residential complex, Rezvan residential complex, Rahan residential complex, Hasht Behesht residential complex and Zeytoun residential complex as the basis of the research case. Among the samples studied, Rahan residential complex has the lowest connectivity index compared to other complexes; the largest share of this comparison goes to Kasra residential complex. In the meantime, Zeytoun residential complex, then Azadi, Hasht Behesht and Rezvan have the lowest to the highest amount. It can be seen that the public spaces of Rahan residential complex do not have the desired level of connectivity. As the communication increases, the spaces will become more sociable. From the comparison of the complexes based on the interconnection index, we conclude that the location of the spaces and accesses in the Rahan complex is very weak and lower than the rest of the complexes. According to the numbers extracted, Zeytoun complex and following that Kasra and Rezvan complexes are at the same level of performance, and Azadi and Hasht Behesht complexes have the best performance in this aspect; the placement of access and communications in Kasra and Rezvan complexes has been appropriate and successful. It is said that the increase of connection in public spaces occurs with the increase of sociability. Among the investigated sociability components, the spatial Order component with the path coefficient value of 0.368 has the highest path coefficient. In the first place the playability component with a path coefficient of 0.253 is in the second place, and the multipurpose component with a path coefficient of 0.231. In the third place, the security component, with a path coefficient of 0.162, is in the fourth place, and the environmental comfort component is in the fifth place, with a path coefficient of 0.153.     Conclusion Living in the common spaces of residential complexes allows one to be with others comfortably and effortlessly. A person can take a usual walk to be among people, sit on a bench near the door for a short time, and even sometimes look out of the window can be a worthwhile activity. In this research, an attempt was made to examine the condition of the studied residential complexes from the perspective of sociability. The results showed that Rahan residential complex had the lowest level of connectivity index compared to the rest of the complexes and the largest share of this. The comparison reaches Kasra residential complex. In the meantime, Zeytoun residential complex, then Azadi, Hasht Behesht and Rezvan have the lowest to the highest amount. It can be seen that the public spaces of Rahan residential complex do not have the desired level of connectivity. As the communication increases, the spaces will become more sociable.

چکیده: 

Khwaja Yusuf Hamadani is one of the great mystics of Iran during 11th and 12th centuries. Being one of the Sufi masters of Naqshbandi Sufi Order, he has an important position among them. The most prominent Sufi master in Naqshbandi Order named Khwaja Abdul Khaliq Ghujdvani is connected to the Holy Prophet in two ways through Khwaja Yusuf Hamadani. There are four persons between Khwaja Yusuf Hamadani and Imam Jafar Sadiq: Abu Ali Farmadi, Abul Qasem Korregan, Abul Hasan Kharaghani, and Bayazid Bastami, Imam Sadiq. And there are two ways from Imam Jafar Sadiq to the Holy Prophet both of them are valid according to the Naqshbandi Order. The main difference between Naqshbandi and other Sufi Orders is that while all Sufi Orders are connected to the Holy Prophet through Imam Ali, the Naqshbandi Order is the only Sufi Order that has chosen Abu Bakr to be connected to the Holy Prophet. And because of this difference, the Naqshbandi Order is being criticized and denied by the other Sufi Orders. By the use of historical sources, this essay first of all tries to analyze the relationship between Khwaja Yusuf Hamadani and Naqshbandi Sufi Order, and then to introduce his masters and teachers especially his unknown master Abdullah Juni about whom there are a few knowledge.
