Neuroticism and internet addiction : What is next? A systematic conceptual review

Marciano, Laura ; Camerini, Anne-Linda ; Schulz, Peter J.

In: Personality and individual differences, 2022, vol. 185, p. 10

The personality trait of neuroticism (N) has consistently shown to be a risk factor for Internet Addiction (IA). Review literature, however, looked at this in bivariate analyses only. To the best of our knowledge, we conducted the first review that systematically and conceptually summarized results based on the inclusion of additional factors, thus coming closer to the complex nature of the ...

The Co-evolution of Public Relations and Journalism : a First Contribution to Its Systematic Review = Ko-Evolution von Public Relations und Journalismus: Ein erster Beitrag zu ihrer systematischen Aufarbeitung

Schönhagen, Philomen ; Meissner, Mike

In: Public Relations Review, 2016, vol. 42, p. 748-758

There are many research findings and some theoretical models regarding the interaction between journalism and public relations (PR). But only scarce research has been done so far on the historical perspective of this relationship, which is also called co-evolution of PR and journalism. The aim of this article is to make a first step into the analysis of this co-evolution with a focus on the...

Scalable Recovery of Missing Blocks in Time Series With High and Low Cross-correlations

Khayati, Mourad ; Cudré-Mauroux, Philippe ; Boehlen, Michael

In: Knowledge and Information Systems, 2020, vol. 62, p. 2257-2280

Missing values are very common in real-world data including time-series data. Failures in power, communication or storage can leave occasional blocks of data missing in multiple series, affecting not only real-time monitoring but also compromising the quality of data analysis. Traditional recovery (imputation) techniques often leverage the correlation across time series to recover missing...

Wiki2Prop : A Multimodal Approach for Predicting Wikidata Properties from Wikipedia

Luggen, Michael ; Audiffren, Julien ; Difallah, Djellel Eddine ; Cudré-Mauroux, Philippe

In: The Web Conference 2021, Ljubljana, Slovenia, April 12-23, 2021, 2021, p. 1-10

Wikidata is rapidly emerging as a key resource for a multitude of online tasks such as Speech Recognition, Entity Linking, Question Answering, or Semantic Search. The value of Wikidata is directly linked to the rich information associated with each entity – that is, the properties describing each entity as well as the relationships to other entities. Despite the tremendous manual and...

RETA : A Schema-Aware, End-to-End Solution for Instance Completion in Knowledge Graphs

Rosso, Paolo ; Yang, Dingqi ; Ostapuk, Natalia ; Cudré-Mauroux, Philippe

In: The Web Conference 2021, Ljubljana, Slovenia, April 12-23, 2021, 2021, p. 1-12

Knowledge Graph (KG) completion has been widely studied to tackle the incompleteness issue (i.e., missing facts) in modern KGs. A fact in a KG is represented as a triplet (ℎ, 𝑟, 𝑡 ) linking two entities ℎ and 𝑡 via a relation 𝑟 . Existing work mostly consider link prediction to solve this problem, i.e., given two elements of a triplet predicting the missing one, such as (ℎ,...

ORBITS : Online Recovery of Missing Values in Multiple Time Series Streams

Khayati, Mourad ; Arous, Ines ; Tymchenko, Zakhar ; Cudré-Mauroux, Philippe

In: Proceedings of the VLDB Endowment, 2020, vol. 14, no. 3, p. 294-306

With the emergence of the Internet of Things (IoT), time series streams have become ubiquitous in our daily life. Recording such data is rarely a perfect process, as sensor failures frequently occur, yielding occasional blocks of data that go missing in multiple time series. These missing blocks do not only affect real-time monitoring but also compromise the quality of online data analyses....
