From Word Embeddings to Item Recommendation
This work addresses recommendation systems for social network users, but it is incremental as it adapts an existing method to a new domain with non-textual features.
The authors tackled the problem of venue recommendation by applying Word2Vec, a natural language processing technique, to non-textual check-in data from Foursquare, showing that this approach is promising for making recommendations.
Social network platforms can use the data produced by their users to serve them better. One of the services these platforms provide is recommendation service. Recommendation systems can predict the future preferences of users using their past preferences. In the recommendation systems literature there are various techniques, such as neighborhood based methods, machine-learning based methods and matrix-factorization based methods. In this work, a set of well known methods from natural language processing domain, namely Word2Vec, is applied to recommendation systems domain. Unlike previous works that use Word2Vec for recommendation, this work uses non-textual features, the check-ins, and it recommends venues to visit/check-in to the target users. For the experiments, a Foursquare check-in dataset is used. The results show that use of continuous vector space representations of items modeled by techniques of Word2Vec is promising for making recommendations.
