Abstract
This paper focuses on the construction of an automatic ontology tree which is capable of dynamically updating information for efficient management of up–to–date information in the domain of mobile phones. The proposed system takes the URL of the most relevant website as input. It acquires information from web pages that are related to the domain and based on those information automatically constructs the ontology tree. To make the ontology tree up–to–date periodic comparison of the values are made with information available over the internet, outdated information is pruned and updates are merged into the ontology tree dynamically. The constructed ontology tree can be queried with domain–related queries and the ontology tree provides relevant result for the query. The proposed system is suited for domains that make frequent updates because it takes special care on dynamically monitoring changes on the web and performing updates on par with it.
