Existing timeline generation systems for complex events consider only information from traditional media, ignoring the rich social context provided by user-generated content that reveals representative public interests or insightful opinions. We instead aim to generate socially-informed timelines that contain both news article summaries and selected user comments. We present an optimization fra...

We investigate an important and challenging problem in summary generation, i.e., Evolutionary Trans-Temporal Summarization (ETTS), which generates news timelines from massive data on the Internet. ETTS greatly facilitates fast news browsing and knowledge comprehension, and hence is a necessity. Given the collection of time-stamped web documents related to the evolving news, ETTS aims to return ...

Location histories are rapidly becoming easily collectable and offer new opportunities for personal reminiscing. However, while location history data contains both temporal and location information, maps provide the location content while downplaying temporal aspects and timelines focus on the temporal sequence, minimizing the spatial aspects. In contrast, autobiographical memories incorporate ...

Clinical TempEval 2017 aimed to answer the question: how well do systems trained on annotated timelines for one medical condition (colon cancer) perform in predicting timelines on another medical condition (brain cancer)? Nine sub-tasks were included, covering problems in time expression identification, event expression identification and temporal relation identification. Participant systems we...

The planning and implementation of infrastructure projects is a long-term enterprise that involves debates over the many positive negative impacts. Previous work has examined questions about conditions for effective environmental governance infrastructure, but typically focused on individual short time frames. We therefore pursued an historical approach to across multiple cases, taking up examp...

The coronavirus pandemic has inundated the globe with discussions of time. Incubation periods, contagion intervals, exponential growth curves, hospitalization timelines, belated government response...
