Abstract: System and method for providing itinerary services for travelers and users, where the travelers travel in at least one predefined traveling area. The system includes mobile communication devices, each of which comprises a positioning system enabled to locate the location of the device. Each device further enables the traveler to document the journey by enabling the traveler to acquire and insert content data and transmit the content data; at least one virtual travel journal enabling each traveler to document his journey by acquiring content data that is associated with the location of the traveler at the time the content was acquired. The system may also include at least one visual online viewer enabling a user to monitor the traveling of the traveler in real time; and a main server that enables receiving, processing, analyzing and storing data transmitted from the virtual travel journal, and presenting the data in real time to users through the visual online viewer.

Abstract: The present invention is a new and efficient means for abstracting answers to questions from a given repository of data, which is either personal knowledge or a textbook. It provides the means for retrieving full answers for complex questions via a PDA-oriented, user friendly interface. The system, which may combine textual as well as other forms of data files (e.g. images, movie and sound files), allows users to retrieve the necessary data from modularly constructed questions using the relevant key words in a simple two click operation. The system is comprised of a set of terms and optionally multimedia objects, a set of relations, a set of meta-relations. Combined they create a set of basic facts and a set of inferred facts. A term is a textual, an object may be text, image, audio, and video files. A relation on term is a phrase that describes any relationship between two terms.
