Flexible Trip-Planning Queries

The current practice of users searching for different types geo-resources in a geographic area and wishing to identify the most convenient routes visiting relevant ones, requires iterative formulation several queries: first more interesting resources then select best route visit them. In order simplify this process, paper novel functionality information retrieval (GIR) system is proposed, which retrieves ranks number georeferenced as result single query, named flexible trip-planning query. An original model defined rank by taking into account personal user preferences. To end, graph-based algorithm defined, exploiting prioritized aggregation optimize routes’ identification ranking. proposed applied proof-of-concept Smart cOmmunity-based Geographic infoRmation rEtrievAl SysTem (SO-GREAT) designed strengthen local communities: it collects manages open data from regional authorities describing categories authoritative territorial services, such schools, hospitals, etc., volunteered services (VGSs) created citizens offer their neighbourhood.
