Determining the Consistency of Information between Multiple Systems Used in Maritime Domain Awareness

摘要

Multiple public web sites can be used to obtain ship-related information that is relevant to maritime domain awareness (MDA). However, the quality or timeliness of this information can be suspect. In this work, a software application, called the consistency application, is developed for the cross comparison of ship-related information from multiple data sources. The consistency application allows a researcher to cross compare the information from these multiple data sources and generate a comparison score for the source specific ship information and also for the data source as a unit. This allows the researcher to assess the consistency of the information provided from the data source as compared to other sources. The consistency application presently links the Automated Ship Image Acquisition (ASIA) system and the SeaSpider application. Information from the International Telecommunication Union is also utilized as both a data source and a means to identify single ship entities.
