=====================================================

BACKGROUND AND SCOPE
Automated recommendations have become a pervasive feature of our online 
user experience. Historically, the two main approaches of building 
recommender systems are collaborative filtering (CF) and content-based 
filtering (CB). In more recent years, this dichotomy has become more and 
more blurred, and we observe various attempts to incorporate additional 
side information and external knowledge sources into the recommendation 
process, regardless of the adopted recommendation approach. This side 
information predominantly contains additional knowledge about the 
recommendable items, e.g., in terms of their features, metadata, 
category assignments, relations to other items, user-provided tags and 
comments, or related textual or multimedia content.

The goal of the special issue is to highlight recent progress in the 
area of recommender systems that propose novel approaches to identify, 
extract, process, and leverage information about the items in the 
recommendation process.

TOPICS
* Utilizing side information about items for user modeling and 
recommending including structured sources, e.g., DBpedia, Linked Open 
Data, BabelNet, Wikidata; textual sources, e.g., Wikipedia or 
User-Generated Content like tags, reviews, and comments; and multimedia 
("low-level") features, e.g., videos or musical signals
* Approaches that rely on a semantic (deep) understanding of items and 
their features based, e.g., on formal ontologies
* Applying deep learning methods to model item features
* Leveraging rich item representations for more effective user modeling 
and recommendation
* Using side information about items to increase recommendation quality 
in terms of novelty, diversity, or serendipity
* Using side information about items to explain recommendations to users
* Leveraging side information and external sources for cross-lingual 
recommendations
* Using side information about items for transparent user modeling 
compliant with the General Data Protection Regulation
* Novel applications areas for recommender systems (e.g., music or news 
recommendation, off-mainstream application areas) based on item side 
information
* User studies (e.g., on the user perception of recommendations), field 
studies, in-depth experimental offline evaluations
* Methodological aspects (evaluation protocols, metrics, and data sets)
