    One of the causes of ships’ accidents are errors in the communication between navigators in charge of ships concerned. The most common causes include a lack of communication, misunderstanding of a received message, incorrect choice of the type of message or misinterpretation of the information exchanged. These errors can be significantly reduced by the automation of intership communication processes, in particular by a developed automatic maritime communication system. The decision to communicate is as essential as communication itself. This paper presents the problem of identifying situations requiring the establishing of communication by a sea-going vessel. A definition of the need to establish communication between the vessels is associated with the acquisition of data, analysis and evaluation of the navigational situation and the relevant inference process. Based on an analysis of the process of identifying navigation situations which require communication between proceeding ships, the model of automatic identification of such situations has been develope

    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.

    Automatic communication can help reduce errors in communication between navigators, and, consequently, increase the level of navigation safety. This article reviews some methods for the development of an ontology and looks into processes for communication at sea. Three basic elements of ontology can be distinguished: navigational information, communication and interface. The possibility of applying these methods for the construction of ontology was analyzed for a system of automatic communication at sea.
