  1. Hybrid Deep-Semantic Matrix Factorization for Tag-Aware Personalized Recommendation

    2017 · arXiv (Cornell University)

    Matrix factorization has now become a dominant solution for personalized recommendation on the Social Web. To alleviate the cold start problem, previous approaches have incorporated various additional sources of information into traditional matrix factorization models. …

  2. Stable Model Semantics for Guarded Existential Rules and Description Logics: Decidability and Complexity

    2021 · Journal of the ACM

    This work investigates the decidability and complexity of database query answering under guarded existential rules with nonmonotonic negation according to the classical stable model semantics. In this setting, existential quantification is interpreted via Skolem functions, …

  3. Tag-Aware Personalized Recommendation Using a Deep-Semantic Similarity Model with Negative Sampling

    2016

    With the rapid growth of social tagging systems, many efforts have been put on tag-aware personalized recommendation. However, due to uncontrolled vocabularies, social tags are usually redundant, sparse, and ambiguous. In this paper, we propose …

  4. e-SNLI: Natural Language Inference with Natural Language Explanations

    2018 · arXiv (Cornell University)

    In order for machine learning to garner widespread public adoption, models must be able to provide interpretable and robust explanations for their decisions, as well as learn from human-provided explanations at train time. In this …
