Abstract: A method for travel planning, based on object-oriented technology, performed on an electronic system including one or more electronic front-end sides, as clients, at least one electronic backend side, as server, one or more storing databases bidirectionally connected to the backend side, includes the following steps: logging in and accessing the electronic system through the frontend side; starting communication between the electronic front end side and backend side; performing a validation process and creating at least a new UGC at the front end side, sending it to the backend side, and storing it in the storing databases; through a content manager module, at the backend side, analyzing the UGC and assigning a ranking score to the UGC, creating an object by associating the UGC and thhe scoring, and additional information of geotagging and category, the additional information coming from the frontend side and/or from the storing databases, storing the object in the storing databases; through a search manager

Abstract: An electronic system for travel route building, adapted to build multimodal itinerary routes including data relating to starting location, target location, intermediate location nodes, segments connecting the intermediate nodes and the starting and target location, including the following electronic modules: a search manager module receiving requests for travel route building from an electronic client device including data relating to the starting location and target location, and managing the building up of a number of the multimodal itinerary routes having the starting location and target location, to be submitted to the electronic client device for selection of the travel route between the starting location and target location; a harvesting module, controlled by the search manager module to perform data queries in an internal relational database and in external service providers' databases to get data relating to alternatives for the intermediate location nodes, segments connecting the intermediate nodes,
