This paper explores advanced data mining techniques for personal navigation systems, focusing on location-based services. It highlights the importance of retrieving relevant information based on a user's context, preferences, and real-time location. By integrating traditional relevance factors such as keywords and user profiles with additional criteria like geographic coordinates, the study presents a novel approach to keep mobile users informed and equipped. It aims to improve navigational guidance and information retrieval, ensuring users receive tailored suggestions during their journeys.

Personal Navigation Location information is used for: • Plotting location of user on a map • Navigational guidance to given destination • Provide data related to location
Data mining required • For retrieval of location-related information from www (Web mining) • For Task-oriented data extraction from web documents • For user profiling (additional parameters for defining what is relevant)
Traditional definition of relevance • Keyword • Web-Based Search Engines • User Profile • Past Behavior of self and community define the profile • Automatic suggestions (e.g. Amazon.com proposed other “relevant” books)
Novel Approach to Data(Web)-Mining for a MOBILE USER • Key is to find RELEVANT information • Re-defining Relevance for Mining Web • Relevance depends on • User request at the moment • User preferences • Relevance = Traditional Parameters (Keywords, Profile) + LOCATION
Additional relevance factor: Location • Co-ordinates of mobile User City/Street address • Relevance=Location + Keywords (+Profile) • For example: • Helsinki downtown • “Restaurant” • “Budget prize” “Vegetarian”
Issues for a Personal Navigation System with the NEW Definition • Spot the client on the Globe • Co-ordinate Location interconvertion • Data Extraction: Task oriented search of web • Scalability (in accordance with User’s Mobile Device) • User profile learning • Pass Relevant Information to the Mobile User
