A Semi-Supervised Model for Top-N Recommendation

Shulong Chen, Yuxing Peng
2018 Symmetry  
Top-N recommendation is an important recommendation technique that delivers a ranked top-N item list to each user. Data sparsity is a great challenge for top-N recommendation.  ...  Therefore, we select a certain number of items ranked higher in the recommendation list to construct an intermediate set and optimize the metric Area Under the Curve (AUC).  ...  We made an assumption about users' relative preferences among unrated items and put forward an approach to build an intermediate set and optimize the AUC metric. 2.  ...

If accurate top-N recommendation lists are to be produced for such graded relevance domains, it is critical to generate a ranked list of recommended items directly rather than predicting ratings.  ...  Experimental results show that GAPfm achieves substantial improvements on the top-N recommendation task, compared to several state-ofthe-art approaches.  ...  In a similar spirit, TFMAP [28] directly optimizes Average Precision for context-aware recommendations. All of these methods use binary implicit-feedback data.  ...

2017 Journal of the Brazilian Computer Society  
We focus on exploiting the impact that different feature extraction techniques, allied with sentiment analysis, cause in an item attribute-aware neighborhood-based recommender algorithm.  ...  Beyond the traditional recommender strategies, there is a growing effort to incorporate users' reviews into the recommendation process, since they provide a rich set of information regarding both items  ...  We evaluated this scenario by selecting the top 100 items with the highest predicted ratings for each user and applied the precision at n (prec@n) and the mean average precision (MAP) measures.  ...
