Defining Contextual Factors for News Consumption

Benjamin Kille, Özlem Özgöbek, Andreas Lommatzsch
2018 International Conference on Information and Knowledge Management  
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.  ...

Spatio - Temporal Context Anomaly Detection for Residential Power Consumption

Nurhidayat Sisworahardjo, Akram A. Saad
2017 International Journal on Electrical Engineering and Informatics  
The proposed algorithm computes an anomaly score for each user by considering historical consumption data.  ...  The anomaly score for a user is then adjusted by analyzing other contextual variables such as seasonal variation day of the week and other users with the same historical pattern.  ...  The algorithm is flexible regarding identifying new contextual features such holidays.  ...

Information Entropy Theory Based Recognition of the Validity of Contextual Information of Restaurants: An Empirical Study

2019 Tehnički Vjesnik  
Contextual information plays a key role in personalized recommendations. However, not all contextual information plays a positive role in personalized recommendations.  ...  Therefore, it is critical to identify the effective contextual information to realize personalized recommendations.  ...  In the existing studies, the introduction of contextual factors depends more on the researchers' understanding of the application field, for instance, the choice of "location" as a contextual factor to  ...

Towards delicate anomaly detection of energy consumption for buildings: enhance the performance from two levels

Dong Wang, Therese Enlund, Johan Trygg, Mats Tysklind, Lili Jiang
2022 IEEE Access  
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  ...

A Contextual Anomaly Detection Framework for Energy Smart Meter Data Stream [chapter]

Xiufeng Liu, Zhichen Lai, Xin Wang, Lizhen Huang, Per Sieverts Nielsen
2020 Communications in Computer and Information Science  
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.  ...
