FRIEND RECOMMENDATION USING LDA ALGORITHM

“Friend Recommendation using LDA Algorithm” is a novel semantic-based friend recommendation system for social networks,recommends friends to users based on their activity bag instead of social graphs. Existing social networking services recommend friends to users based on their social graphs, which may not be the most appropriate to reflect a user's preferences on friend selection in real life. Inspired by text mining, we model a user's daily life as life documents, from which his/her life styles are extracted by using the Latent Dirichlet Allocation algorithm. We further propose a similarity metric to measure the similarity of life styles between users, and calculate users' impact in terms of life styles with a friend-matching graph.So,our system integrates a feedback mechanism to further improve the recommendation accuracy. This system will be used on the Android-based smartphones.
