opentrep

opentrep aims at providing a clean API, and the corresponding C++ implementation, for parsing travel-focused requests. It powers the https://transport-search.org Web site. opentrep uses Xapian (https://www.xapian.org) for the Information Retrieval part, on freely available travel-related data (e.g., country names and codes, city names and codes, airline names and codes, etc.), mainly to be found in the OpenTravelData project (https://github.com/opentraveldata/opentraveldata). The data files are available from https://transport-search.org/data/optd/por/ opentrep exposes a simple, clean and object-oriented, API. For instance, the OPENTREP::interpretTravelRequest() method takes, as input, a string containing the travel request, and yields, as output, the list of the recognized terms as well as their corresponding types. As an example, the travel request 'Washington DC Beijing Monday a/r +AA -UA 1 week 2 adults 1 dog' would give the following list: * Origin airport: Washington, DC, USA * Destination airport: Beijing, China * Date of travel: next Monday * Date of return: 1 week after next Monday * Preferred airline: American Airlines; non-preferred airline: United Airlines * Number of travelers: 2 adults and a dog The output can then be used by other systems, for instance to book the corresponding travel or to visualize it on a map and calendar and to share it with others. opentrep makes an extensive use of existing open-source libraries for increased functionality, speed and accuracy. In particular the Boost (C++ Standard Extensions: https://www.boost.org) and SOCI (https://github.com/SOCI) libraries are used. Note that opentrep currently only recognizes points of reference (POR), as to be found in the following file: https://bit.ly/3fQaddv A good complementary tool is GeoBase (https://opentraveldata.github.io/geobases), a Python-based software able to access to any travel-related data source.
