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)


Overall Scheme


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


Possible use scenario


Scenarion including user profiling


WE REGRET...
