SERecSys: Second Workshop on Semantics-Enabled Recommender Systems

IEEE International Conference on Data Mining (ICDM) - November 18 2017, New Orleans (U.S.A.)

Abstract:

Recommender systems are widely used in different applications to support users in exploring possibly interesting items. To go beyond the use of preferences expressed in form of ratings, a recent research trend is to analyze the description of items and enrich the recommendation process with semantic knowledge. Different solutions have been proposed so far, however semantic technologies are moving at a very rapid pace, so there are wide margins for semantic recommenders to advance in their tasks and also to lead to a shift into new paradigms, such as cognitive recommender systems. In this workshop, we aim to collect novel ideas in this field and to provide a common ground for researchers working in this area.

VOODOO SESSION ANNOUNCENT

We are glad to announce the introduction of a novel session at this year’s SERecSys workshop. This session, which will change for every edition of the workshop, is inspired by the location of the workshop. Being the event located in New Orleans, this year’s theme is “voodoo”, as an homage to the local culture.

The Voodoo Session will contain presentation of ideas and insights, along with the results that validate these ideas, to have quick and inspiring exchanges among the workshop attendants. Please, visit the call for papers for more details on the “Insights and results papers”, and the Voodoo Session!

Call for Papers:

A recommender system is designed to suggest items that are expected to interest a user. In order to filter the items and produce the recommendation, Data Mining techniques are largely employed. Among the most popular recommendation approaches in the literature and in real-world applications (e.g., e-commerce websites) are the so-called content-based recommender systems. Content-based recommender systems suggest to users items that are similar to those they previously evaluated [1]. The early systems used relatively simple retrieval models, such as the Vector Space Model, with the basic TF-IDF weighting.

Simple (word-based) interest descriptions may fall short both because of semantic ambiguity and because they lack of generality. Recently, content-based recommender systems evolved and started employing external knowledge sources (e.g., ontologies) to improve accuracy and scope of recommendations [1], [2].

More recent approaches have been based on deep learning [3]. Other approaches, such as [4], have employed word embeddings in the recommendation process. Among the best known and high-performance implementations following these lines of research we mention Google’s word2vec.

Moreover, semantic technologies will soon find a connection with cognitive computing [5], cooperating in the definition of the so-called cognitive recommender systems. Given the rapid advances of Semantic Technologies, there is still a large number of options for recommender systems to take advantage of semantics.

Our workshop will solicit contributions in all topics related to employing Semantic Technologies in Recommender Systems, focused (but not limited) to the following list:

  • Novel approaches to user profiling in recommender systems that model behavior with semantic technologies;
  • Cognitive recommender systems;
  • Content-based recommendation algorithms that employ novel uses of semantic technologies;
  • Recommendation explanation using semantic technologies;
  • Generation of novel, diverse, and serendipitous recommendations using semantic technologies;
  • Hybrid recommender systems that combine semantic technologies with other recommendation techniques (e.g, collaborative);
  • Group-based approaches that use semantic technologies to describe the group preferences or to generate recommendations.

Types of contributions:

We will consider three different submission types, all in the IEEE 2-column format: regular (8 pages), short (4 pages) and extended abstracts (2 pages).

Research and position papers (regular or short) should be clearly placed with respect to the state of the art and state the contribution of the proposal in the domain of application, even if presenting preliminary results. In particular, research papers should describe the methodology in detail, experiments should be repeatable, and a comparison with the existing approaches in the literature should be made where possible. Position papers should introduce novel point of views in the workshop topics or summarize the experience of a researcher or a group in the field.

Insights and results papers (short) should provide a presentation of ideas and insights, along with the results that validate these ideas, to have quick and inspiring exchanges among the workshop attendants. The “insights and results” papers will be presented in a novel and dedicated “Voodoo Session” (inspired by the location of the workshop), aimed at stimulating these exchanges.

Practice and experience reports (short) should present in detail the real-world scenarios in which Semantic Technologies are employed for recommendation purposes.

Demo proposals (extended abstract) should present the details of a prototype or complete application that employs Semantic Technologies in Recommender Systems. The systems will be demonstrated to the workshop attendees.
