    Automatic communication between computer systems on board and ashore is a necessity. At this stage it is limited to simple exchange of information – the data transmitted in the messages. It is expected that it will take the more complex form soon, allowing the dialogue, the transmission of intentions and conducting negotiations. To make it possible, it is necessary to build suitable ontology, describing the processes of communication at sea. To apply this ontology in information systems it is necessary to present it in a proper representation. This paper presents a method of generating a representation in form of XML-Schema based on the ontology built with the use of Protégé program

    The lack of proper communication between navigators is one of the many causes of dangerous situations in maritime transport. Automation of communication processes, in particular negotiation processes, can help either avoid such situations or, when they do occur, deal with them more promptly and effectively. We have characterized inference processes in maritime communication and the communication subontology used to describe these processes. The negotiating processes involving two or more parties are considered. An example is given of an encounter by three ships that requires communication (including negotiations) between the three navigators. We also present how the described communication processes can be automated using the developed subontology of communication.

    One of the factors affecting a ship’s safety during its voyage is the ability to detect encounter situations. Navigators mostly use two parameters: closest point of approach (CPA) and time to CPA (TCPA). Their limit values, considered as safe, depend on the parameters of the vessel, geographic area, and weather conditions. These limits are set by the navigator and are based on his experience; however, in specific situations, there is a need to use other parameters, such as ship domain. It is very important for the automated communication system to determine the critical moment when intership communication should be started. The article presents an algorithm of automatic detection of situations where the communication should be initiated. The influence of data relating to the vessel, geographic area, and weather conditions can be taken into account. The output produced by the program, based on the authors’ algorithm, is presented.
