Integrating multiple conflicting sources by truth discovery and source quality estimation
… human labeling and lack of experts. To find the truth of each entity, much research work has shown that considering the quality of information providers can improve the performance of data integration. Due to different quality of data sources, it is hard to find a general solution that works for …

Modeling trustworthy opinion using an uncertainty-aware approach
… is provided by multiple sources. Traditional truth discovery task aims to identify the truth – the most trustworthy information, from conflicting sources in different scenarios. In this kind of tasks, truth is regarded as a fixed value or a set of fixed values. However, in a number of …

Learning from multiple heterogeneous sources - Handling source trustworthiness and incompleteness
… conflicting answers to the same question. Truth discovery is to infer the most accurate and complete integrated answers from conflicting sources with heterogeneous source quality. In some cases, there exist questions for which the true answers are excluded from the candidate answers …

Mining social sensing data: Representation, modeling, and applications
… of analytical likelihood models. We consider truth discovery that estimates the veracity of claims made by different users with unknown reliability on social media. We then extend the truth-finding algorithm by considering additional content features to further improve the quality estimation …

Statistical inference based on characteristic functions for intractable likelihood problems
… includes my another project, which is about truth discovery in data mining. A dynamic model is developed to discover the truth between information sources across time. Experiments on real-world applications demonstrate its advantages over previous approaches.

On quantifying the quality of information in social sensing
This thesis develops the fundamental theory and methodology for quantifying the Quality of Information (QoI) in social sensing. We refer social sensing to the sensing applications where humans play a critical role in the sensing or data collection process. Social sensing has emerged as a new …
