Recommender System for Web Articles
Kočí, Jan ; Kesiraju, Santosh (oponent) ; Fajčík, Martin (vedoucí práce)
Recommender systems for web articles are the main interest of this thesis. It explains the most popular approaches used to build these systems, proposes a neural-network-based architecture applying the Skip-gram inspired negative sampling method to the recommendation problem, implements this architecture together with several other models, using Singular value decomposition, collaborative filtering with Alternating Least Squares (ALS) algorithm and a content-based approach using the Doc2Vec algorithm to create document vectors from the obtained articles. Finally, it implements three evaluation metrics - namely the RANK metric, Recall at k and Precision at k - and compares the models with state-of-the-art. Apart from that it also gives a brief discussion on the role and purpose of these systems together with the motivation of using them.
