主 题:Recommendation system geotagged photos social media model-based approach support vector machine(SVM) gradient boosting regression tree(GBRT)
摘 要:When travelling,people are accustomed to taking and uploading photos on social media websites,which has led to the accumulation of huge numbers of geotagged *** with multisource information(***,transportation,or textual information),these geotagged photos could help us in constructing user preference profiles at a high level of ***,using these geotagged photos,we built a personalised recommendation system to provide attraction recommendations that match a user’s ***,we retrieved a geotagged photo collection from the public API for Flickr(***)and fetched a large amount of other contextual information to rebuild a user’s travel *** then created a model-based recommendation method with a two-stage architecture that consists of candidate generation(the matching process)and candidate *** the matching process,we used a support vector machine model that was modified for multiclass classification to generate the candidate *** addition,we used a gradient boosting regression tree to score each candidate and rerank the ***,we evaluated our recommendation results with respect to accuracy and ranking *** with widely used memory-based methods,our proposed method performs significantly better in the cold-start situation and when mining‘long-tail’data.
