DEVICE AND METHOD FOR MOBILITY PATTERN MINING |
摘要 |
A mobility pattern mining device includes: a data collecting unit configured to collect a user's historical data; a stay point obtaining unit configured to obtain stay points of the user from the historical data; an extracting unit configured to obtain a semantic tree for a certain topic and extract topic related stay points from the stay points of the user by using the semantic tree for the certain topic; a determining unit configured to determine a candidate mobility pattern of the user based on the topic related stay points; and a selecting unit configured to select a frequent mobility pattern which best matches the candidate mobility pattern of the user from a frequent mobility pattern database related to the certain topic, wherein the database is set in advance based on historical data for a plurality of users to obtain mobility patterns about topics for users. |
