RecoMap : an interactive and adaptive map-based recommender
No full textPaper presented at the ACM 25th Symposium On Applied Computing (SAC’10), March 22-26, 2010, Sierre, SwitzerlandWith the growing availability of geo-referenced information on the Web, the problem of spatial information overload has attracted interest both in the commercial and academic world. In order to tackle this issue, personalisation techniques can be used to tailor spatial contents based upon user interests. RecoMap, the system described in this paper, deducts user interests by monitoring user interaction and context to provide personalised spatial recommendations. After an overview of existing recommendation systems within the geospatial domain, the novel approach adopted by RecoMap to produce such recommendations is described. A case study related to a university campus setting is used to outline an application of this technique. Details of the implementation and initial testing of this prototype are provided.Science Foundation IrelandConference detailshttp://oldwww.acm.org/conferences/sac/sac2010

Metrics for Approximate Query Engine Evaluation
No full textThe performance evaluation of the transaction processing in Database
Management Systems used for Decision Support Systems is
the aim of the current TPC-H standard. Decision Support Systems
also include Approximate Query Answering Systems. However,
the TPC-H does not define a methodology to evaluate these
systems, nor does it provide useful metrics. In this paper, we
address the problem related to the extension of TPC-H, in order to
adjust it for the performance evaluation of the engines used in
approximate query processing to provide fast and approximate
responses to analytical queries
