With the development of social network services representing the opinions and merits of the individual users, various services is provided to users. In these services, as the unreliable sharing information occurs, the researches finding the experts have been studied in order to provide the reliable information. In this paper, we propose a new expert search scheme that performs the profile updates analyzing the recent activities of users and considers the reliable scores among users. To generate the dynamic profile, we periodically extract keywords from the recent activities in social networks and measure the similarities for the keywords. We show that our scheme outperforms the existing scheme in terms of search accuracy and computation cost through the various experiments. Our experimental results show that our scheme outperforms the existing son the search accuracy and achieves about 43% performance improvements on search cost over the existing scheme. |
