EFFICIENT WAY OF USER SEARCH LOCATION IN QUERY PROCESSING

Performance Oriented Query Processing In GEO Based Location Search Engines

Geographic location search engines allow users to constrain and order search results in an intuitive manner by focusing a query on a particular geographic region. Geographic search technology, also called location search, has recently received significant interest from major search engine companies. Academic research in this area has focused primarily on techniques for extracting geographic kno...

Query Processing in Location-Based Social Networks

The widespread proliferation of location-acquisition techniques and GPS -embedded mobile devices resulted in the generation of geo-tagged data at unprecedented scale and have essentially enhanced the user experience in locationbased services associated with social networks. Such locationbased social networks allow people to record and share their location and are a rich source of information wh...

Semantic Caching in Location-Dependent Query Processing

Efficient Cross-Device Query Processing

The increasing diversity of hardware within a single system promises large performance gains but also poses a challenge for data management systems. Strategies for the efficient use of hardware with large performance differences are still lacking. For example, existing research on GPU supported data management largely handles the GPU in isolation from the system’s CPU — The GPU is considered th...

Query Processing in Highly-Loaded Search Engines

While Web search engines are built to cope with a large number of queries, query traffic can exceed the maximum query rate supported by the underlying computing infrastructure. We study how response times and results vary when, in presence of high loads, some queries are either interrupted after a fixed time threshold elapses or dropped completely. Moreover, we introduce a novel dropping strate...
