Hybrid Recommender

Smile and Learn is an EdTech digital publisher that offers a smart library of close to 100 educational stories and gaming apps for mobile devices aimed at children aged 2 to 10 and their families. Given the complexity of navigating the content, a recommender system was developed. The system consists of two major components: one that generates content recommendations and another that provides explanations and recommendations relevant to parents and educators. The former was implemented as a hybrid recommender system that combines three kinds of recommendations. Among these, we introduce a collaborative filtering adapted to overcome specific limitations associated with younger users. The approach described in this work was tested on real users of the platform. The experimental results suggest that this recommendation model is suitable to suggest apps to children and increase their engagement in terms of usage time and number of games played.

Abstract: Here we are building an collaborative filtering matrix factorization based hybrid recommender system to recommend movies to users based on the sentiment generated from twitter tweets and other vectors generated by the user in their previous activities. To calculate sentiment data has been collected from twitter using developer APIs and scrapping techniques later these are cleaned, stemming, lemetized and generated sentiment values. These values are merged with the movie data taken and create the main data frame.The traditional approaches like collaborative filtering and content-based filtering have limitations like it requires previous user activities for performing recommendations. To reduce this dependency hybrid is used which combines both collaborative and content based filtering techniques with the sentiment generated above. Keywords: machine learning, natural language processing, movie lens data, root mean square equation, matrix factorization, recommenders system, sentiment analysis

Mencari pekerjaan secara online dapat menjadi kendala tersendiri baik pada pada pelamar pekerjaan maupun pada perusahaan yang mencari karyawan. Saat ini banyak pelamar dan perusahaan lebih memilih menggunakan situs rekruitasi online dibandingkan mencari dengan menggunakan mesin pencari. Recommender system menjadi salah satu kelebihan dari website rekruitasi karena website menyimpan informasi profil pekerja lalu memberikan rekomendasi sesuai dengan data yang mereka dapatkan. Pada penelitian ini penulis membuat hybrid recommender system dengan menggabungkan dua teknik yaitu knowledge based recommender system yang akan merekomendasikan pekerjaan berdasarkan profil user, kualifikasi pekerjaan dan pengaruh dari user lain yang akan memberikan rekomendasi pekerjaan berdasarkan user lain yang memiliki kesamaan. Hasil prediksi dari 2 metode itu akan digabungkan berdasarkan social aperture yang diberikan. Berdasarkan hasil pengujian hybrid recommender system memberikan hasil terbaik untuk memprediksi interaksi dan memberikan rekomendasi berdasarkan hasil RMSE dan f1 score.

E-Commerce has become very popular these days because it is convenient, reliable, and fast to use. In spite of these advantages, online buyers often experience difficulty in searching for products on the web, while online businesses are often overwhelmed by the rich data they have collected and find it difficult to promote products appropriate to specific customers. This paper proposes a hybrid recommender system that uses fuzzy logic to intelligently mine the requirements of each specific customer, together with some previous users' opinions about the product, to recommend a list of optimal products to meet users' needs. Experimental results of the proposed system with different brands of laptops prove its effectiveness.

Hybrid Recommender

With today's information overload, recommender systems are important to help users in finding needed information. In the movies domain, finding a good movie to watch is not an easy task. Emotions play an important role in deciding which movie to watch. People usually express their emotions in reviews or comments about the movies. In this article, an emotional fingerprint-based model (EFBM) for movies recommendation is proposed. The model is based on grouping movies by emotional patterns of some key factors changing in time and forming fingerprints or emotional tracks, which are the heart of the proposed recommender. Then, it is incorporated into collaborative filtering to detect the interest connected with topics. Experimental simulation is conducted to understand the behavior of the proposed approach. Results are represented to evaluate the proposed recommender.
