in this research work, the impact of user’s behavior on search engine results is discussed. it aims to improvement of search results which leads to the higher satisfaction of users. in other words, we are trying to present a personalized search engine for each user, based on his/her activity and search history. we base our hypothesis that the search history of each user in a specific time frame...

In this paper we propose the concept of cache plugins, which are customized programs that run WWW cache servers and perform some of the search engine tasks. We describe a prototype implementation of cache plugin to answer client requests directed to a large search engine, using a nearby cache server to store static objects. Experimental results using actual logs show a signiicant improvement on...

this study aimed to evaluate persian search engines based on the criteria obtained from alexa databank using correspondence analysis. through searching the web, 23 search engines were found, which due to their cease and no coverage by alexa, this number was reduced to 16. data analysis revealed that ghatreh search engine occupied a high rank in most of attributes like traffic rank, time spent o...

We have customized learning object metadata (LOM) for educational resources on the basis of the LOM investigated by IEEE [1] and IMS [2], in order to make it consistent with Japanese K-12 school education.[3] Since many specifications for the metadata are included in the customized LOM, we extracted necessary metadata especially for taking into account the retrieval of educational resources in ...

Designing a customized communications network requires addressing a wide variety of constraints that depend on the specific context and wishes of the intended client. In this article, we make public a benchmark for the evaluation of algorithms on multiple variations of a network design problem. Our initial experiments reveal that good results can be obtained through the integration of graph alg...

We present a constraint-based model and planning engine for manufacturing process planning. By exploiting the expressive power of constraint programming (CP), all relevant, sometimes conflicting pieces of domain knowledge are represented. The planner applies standard propagation techniques and customized search to find cost-optimal solutions in presence of hard, soft and conditional constraints...
