متن کاملGeo-Social Keyword Search
In this paper, we propose Geo-Social Keyword (GSK) search, which enables the retrieval of users, points of interest (POIs), or keywords that satisfy geographic, social, and/or textual criteria. We first introduce a general GSK framework that covers a wide range of real-world tasks, including advertisement, context-based search, and market analysis. Then, we present three concrete GSK queries: (...

متن کاملHybrid Index Structures for Temporal-Textual Web Search
Most Web pages contain temporal information. However, most of previous studies only consider the update time of Web pages rather than fully exploit different temporal features in Web. In this paper, we propose a novel approach to fusing different temporal features in Web pages to build an efficient index structure for temporal-textual Web search. Specially, we focus on update time and content t...
متن کاملEfficient Index Based Query Keyword Search in the Spatial Database
In many real time applications there is a need to represent many real time objects (universities, temples, airports, cities, buildings, lakes and companies etc) in the spatial database. Usually, spatial database objects are mapped with keywords for their reference in business or service applications. Normally, spacial objects are queried with the requirement of minimum inter object distance. No...
