Extending the Qualitative Trajectory Calculus Based on the Concept of Accessibility of Moving Objects in the Paths

Qualitative spatial representation and reasoning are among the important capabilities in intelligent geospatial information system development. Although a large contribution to the study of moving objects has been attributed to the quantitative use and analysis of data, such calculations are ineffective when there is little inaccurate data on position and geometry or when explicitly explaining ...

ارائه روشی پویا جهت پاسخ به پرس‌وجوهای پیوسته تجمّعی اقتضایی

Data Streams are infinite, fast, time-stamp data elements which are received explosively. Generally, these elements need to be processed in an online, real-time way. So, algorithms to process data streams and answer queries on these streams are mostly one-pass. The execution of such algorithms has some challenges such as memory limitation, scheduling, and accuracy of answers. They will be more ...

Application of Information Technology: The Shared Health Research Information Network (SHRINE): A Prototype Federated Query Tool for Clinical Data Repositories

The authors developed a prototype Shared Health Research Information Network (SHRINE) to identify the technical, regulatory, and political challenges of creating a federated query tool for clinical data repositories. Separate Institutional Review Boards (IRBs) at Harvard's three largest affiliated health centers approved use of their data, and the Harvard Medical School IRB approved building a ...

بهبودی در سیستم های پیشنهادگر خبره با استفاده از بسط پرسش و مدل فضای برداری

Due to enormous volume of information available on the Web, finding appropriate knowledge in a short time seems difficult. Knowledge Recommender systems, Online Forums and Question Answering (QA) systems were created to facilitate finding suitable information. QA systems use knowledge repositories to retrieve brief responses to users’ queries. Expert Finding system, not only causes knowledge tr...
