Apart from the spatial location of an object (e.g., a point of interest), additional descriptive information typically includes textual description as well as various ratings, often user generated. Modern applications employ spatio-textual queries, which take into account both the spatial location of an object and its textual similarity to retrieve the most relevant objects. However, existing applications provide a limited functionality to the users. For example, several meaningful queries cannot be expressed by existing approaches and motivate our novel prototype system. The goal of our research is to introduce a novel framework, called Pausanias, for supporting ranked spatial-keyword search over web-accessible geotagged data. In this deliverable, we provide an analysis of requirements that should be fulfilled by the proposed prototype and a concise description of the system design of Pausanias. 20 pp. LOMv1.0 creator LOMv1.0 Project Deliverable Number 2 LOMv1.0 Project Final Beneficiary LOMv1.0 Project Executing Organisation 2013-08-13 Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text Data retrieval Web queries Geotagged data Text retrieval Spatial-keyword search Spatio-textual queries Requirement analysis System design 516631 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/3238/2/3238_D2-requirement%20analysis.pdf URI http://hdl.handle.net/10795/3238 LOMv1.0creator 2016-05-19T08:03:59Z LOMv1.0validator 2016-05-19T08:03:59Z LOMv1.0 gre no no Copyright EYD-EPEDBM (Operational Programme "Education and Lifelong Learning")
