Defining Contextual Factors for News Consumption
2018
International Conference on Information and Knowledge Management
Preserved Fulltext
In this work, we aim to explore the use of contextual information to improve news recommender systems. ...
News shape public perception of events. The amount and frequency with which publishers release articles continues to increase. ...
There is still a need for a better understanding of contextual factors in news recommender systems. In particular, research has yet to determine which contextual features matter in which domain. ...

First, it precisely detected the contextual anomalies concealed beneath the time variation of the energy consumption profiles of the three buildings. ...
The proposed workflow was implemented in a case study for identifying the anomalies in three real-world energy consumption datasets from two types of commercial buildings. ...
The reason is that the contextual attributes (month, day class, and hour) added in the contextualization process help define the environment of the behavioral attribute (energy consumption) for each instance ...

Monitoring abnormal energy consumption is helpful for demand-side management. This paper proposes a framework for contextual anomaly detection (CAD) for residential energy consumption. ...
This framework uses a sliding window approach and prediction-based detection method, along with the use of a concept drift method to identify the unusual energy consumption in different contextual environments ...
Contextual factors often play an important role in influencing energy consumption, which must be taken into account when detecting anomalies. We call it contextual anomaly detection in this paper. ...
