The Key Role of Ontology Alignment and Enrichment Methodologies for Aligning and Enriching Dwipa Ontology with the Weather Concept on the Tourism Domain

The Dwipa Ontology III is a one of many sources of knowledge about the tourism domain in Indonesia. It stores information and its relations mainly about accommodation, attraction, activity, and amenity. However, this particular ontology is lack to present information about weather which highly needed by tourists during traveling to the tourism destinations. Firstly, this research aims to align two sources of weather ontologies: the weather ontology and the weather ontology for smart city in order to create a new concept of weather ontology. This new weather ontology concept is generated by measuring its linguistic similarity. Secondly, this research focus on enriching the concept of initial ontology named the Dwipa Ontology III with the concept generated by ontology alignment approaches. The ontology alignment method has been successfully mapped two weather ontologies into a new concept of weather that consist of 14 literal data: WeatherCondition, WeatherReport, dewPointAtmospere, unit, gustingWind, Celsius, Humidity, AtmosperePressure, Speed, Temperature, Interval, hasDate, hasSpeedValue, and hasUnit. This new concept has been enriched to the Dwipa Ontology III by adding one new concept/ class named weatherReport that consist of four sub classes: Unit, Interval, WeatherCondition and Temperature and a total of 255 instances. This latest version of aligned and enriched ontology is given name as Dwipa Ontology III+.
