Inherent-Cost Aware Collective Spatial Keyword Queries
With the proliferation of spatial-textual data such as location-based services and geo-tagged websites, spatial keyword queries become popular in the literature. One example of these queries is the collective spatial keyword query (CoSKQ) which is to find a set of objects in the database such that it covers a given set of query keywords collectively and has the smallest cost. Some existing cost...
متن کاملSpatial Keyword Query Processing: An Experimental Evaluation
Geo-textual indices play an important role in spatial keyword querying. The existing geo-textual indices have not been compared systematically under the same experimental framework. This makes it difficult to determine which indexing technique best supports specific functionality. We provide an all-around survey of 12 stateof-the-art geo-textual indices. We propose a benchmark that enables the ...
متن کاملThe Flexible Group Spatial Keyword Query
We present a new class of service for location based social networks, called the Flexible Group Spatial Keyword ery, which enables a group of users to collectively nd a point of interest (POI) that optimizes an aggregate cost function combining both spatial distances and keyword similarities. In addition, our query service allows users to consider the trade-os between obtaining a suboptimal ...
متن کاملKeyword Query to Graph Query
Keyword query to graph query is a problem which aims at mapping entities and relationships mentioned in a query to entities and relationships in a knowledge-base. It has a very important application in different domains like that of information retrieval, data mining, genomics etc. Obviously keyword queries are preferred by users because they are based on natural language. Even though this poin...
متن کاملQUASII: QUery-Aware Spatial Incremental Index
With large-scale simulations of increasingly detailed models and improvement of data acquisition technologies, massive amounts of data are easily and quickly created and collected. Traditional systems require indexes to be built before analytic queries can be executed efficiently. Such an indexing step requires substantial computing resources and introduces a considerable and growing data-to-in...
