| Abstract | The widespread use of GPS-enabled cellular devices, i.e., smart phones, led to the popularity of numerous mobile applications, e.g., social networks, micro-blogs, mobile web search, and crowd-powered reviews. These applications generate large amounts of geo-tagged textual data, i.e., spatial-keyword data. This data needs to be processed and queried at an unprecedented scale. The management of spatial-keyword data at this scale goes beyond the capabilities of centralized systems. We live in the era of big data and the big data model is currently been used to address scalability issues in various application domains. This has led to the development of various big spatial-keyword processing systems. These systems are designed to ingest, store, index, and query huge amounts of spatial-keyword data. In this 1.5 hour tutorial, we explore recent research efforts in the area of big spatial-keyword processing. First, we give main motivations behind big spatial-keyword systems with real-life applications. We describe the main models for big spatial-keyword processing, and list the popular spatial-keyword queries. Then, we present the approaches that have been adopted in big spatial-keyword processing systems with special attention to data indexing and spatial and keyword data partitioning. Finally, we conclude this tutorial with a discussion on some of the open problems and research directions in the area of big spatial-keyword query processing. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
