Call for papers: The 1st International Workshop on Temporal Reasoning in
Recommendation Systems (TempRRS 2017)


TempRRS 2017 is co-located with ACM RecSys 2017, 27-30 August 2017 at Como,

Abstract and Topics


The workshop focus is on considering temporal aspects for recommender
systems in general, regardless of the specific domain and application,
trying to develop a holistic approach for dealing with temporal aspects in
recommender system, like personal assistants, news, tourism, health care,
TV, e-commerce, social networks etc. 

Hitherto, temporal aspects of user activity in Recommender Systems were used
in two different scenarios: explicit feedback and implicit feedback. The
first one is related to explicitly expressing ratings for movies, for
example: Netflix prize data set contains timestamps associated with the
ratings. As it was shown using them improved rating prediction. On the other
hand, there is an implicit feedback data: e-commerce logs that describe user
shopping behavior contain timestamps that also can be used in identifying
user patterns (when user tend to purchase more in the morning and towards
the evening; on Mondays rather than the middle of the week, before the
holidays on August rather than other months and so on), building user
profiles, identifying similar users (for CF) and use all this useful
information for items to purchase recommendations. Not only e-commerce, but
other domains with web clickstreams, can be analyzed considering temporal
components. In recent years' Markovian model and sequential pattern-mining
methods were frequently used for such tasks. Recently temporal graphs and
Recurrent Neural Networks are also considered for sequential data analyses
and providing recommendations for people, communities, locations, etc.


The workshop aims at bringing together researchers and practitioners working
on temporal aspects in recommender systems domain in order to look at the
challenges from the point of view of the temporal aspects in user modelling
and recommender systems in order to provide relevant recommendations
regarding the representation and reasoning about temporal aspects. All in
all, the workshop aims at attracting presentations of novel ideas for
addressing these challenges and how to advance the current state of the art
in this field.


Important aspects and topics to be discussed evolve around:

*         Specific applications and case studies where temporal aspects were
considered (evaluation)

*         Specific methods and techniques for integrating temporal aspects
into the recommendations 

*         Integrating data

o    Exploiting data from various sources, i.e., catalogues, Linked Open
Data, and usage logs

*         Context and Mobility

*         Cold-Start Problem

*         Preference Elicitation

*         Temporal Personalization

*         Temporal aspects in group recommendations

*         Cross domain temporal patterns
