Knowledge Graph-based Session Recommendation with Adaptive Propagation

no code implementations17 Feb 2024 Yu Wang, Amin Javari, Janani Balaji, Walid Shalaby, Tyler Derr, Xiquan Cui

Then, we adaptively aggregate items' neighbor information considering user intention within the learned session.

M2TRec: Metadata-aware Multi-task Transformer for Large-scale and Cold-start free Session-based Recommendations

no code implementations23 Sep 2022 Walid Shalaby, Sejoon Oh, Amir Afsharinejad, Srijan Kumar, Xiquan Cui

Using one public and one large industrial dataset, we experimentally show that state-of-the-art SBRSs have low performance on sparse sessions with sparse items.

Session-Based Recommendations

Building chatbots from large scale domain-specific knowledge bases: challenges and opportunities

no code implementations31 Dec 2019 Walid Shalaby, Adriano Arantes, Teresa GonzalezDiaz, Chetan Gupta

Popular conversational agents frameworks such as Alexa Skills Kit (ASK) and Google Actions (gActions) offer unprecedented opportunities for facilitating the development and deployment of voice-enabled AI solutions in various verticals.

Beyond Word Embeddings: Learning Entity and Concept Representations from Large Scale Knowledge Bases

no code implementations1 Jan 2018 Walid Shalaby, Wlodek Zadrozny, Hongxia Jin

We evaluate our concept embedding models on two tasks: (1) analogical reasoning, where we achieve a state-of-the-art performance of 91% on semantic analogies, (2) concept categorization, where we achieve a state-of-the-art performance on two benchmark datasets achieving categorization accuracy of 100% on one and 98% on the other.

Learning Concept Embeddings for Efficient Bag-of-Concepts Densification

no code implementations10 Feb 2017 Walid Shalaby, Wlodek Zadrozny

Once they are learned, we propose an efficient vector aggregation method to generate fully continuous BoC representations.

Solving Cold-Start Problem in Large-scale Recommendation Engines: A Deep Learning Approach

no code implementations16 Nov 2016 Jianbo Yuan, Walid Shalaby, Mohammed Korayem, David Lin, Khalifeh Aljadda, Jiebo Luo

One of the most important features of the proposed technique is the fact that it can be applied on top of any existing CF based recommendation engine without changing the CF core.

Mined Semantic Analysis: A New Concept Space Model for Semantic Representation of Textual Data

no code implementations10 Dec 2015 Walid Shalaby, Wlodek Zadrozny

The study positions MSA as one of state-of-the-art methods for measuring semantic relatedness, besides the inherent interpretability and simplicity of the generated semantic representation.
