Public Transport Ontology for Passenger Information Retrieval

Passenger information aims at improving the user-friendliness of public transport systems while influencing passenger route choices to satisfy transit user’s travel requirements. The integration of transit information from multiple agencies is a major challenge in implementation of multi-modal passenger information systems. The problem of information sharing is further compounded by the multi-l...

Information Retrieval by Imaging

The evaluation of an implication by Imaging is a logical technique developed in the framework of the modal logic. Its interpretation in the context of a \possible worlds" semantics is very appealing for IR. In 1989, Van Rijsbergen suggested its use for solving one of the fundamental problems of IR logical models: the evaluation of the implication d! q (where d and q are respectively a document ...

Private Information Retrieval by Keywords

Private information retrieval (PIR) schemes enable a user to access one or more servers that hold copies of a database and privately retrieve parts of the n bits of data stored in the database. This means that the queries give each individual database no partial information (in the information theoretic or computational sense) on the identity of the item retrieved by the user. All known PIR sch...

Information Retrieval by Logical Imaging

The evaluation of an implication by Imaging is a logical technique developed in the framework of modal logic. Its interpretation in the context of a \possible worlds" semantics is very appealing for IR.
