As search applications keep gathering new and diverse information sources, presenting relevant information anchored in time becomes more important. Temporal information is available in every document either explicitly, e.g., in the form of temporal expressions, or implicitly in the form of metadata. Recognizing such temporal information and exploiting it for document retrieval and presentation ...

Across many cultures, people create spatial representations of time. The direction of mental timelines often follows the direction of writing in a person's language. A new study demonstrates that blind participants (who read with their hands) also show mental timelines that follow reading direction.

Historical data items are often semantically inter-related, such as news events that build on past events. Such inter-related data have so far been visualized primarily with simple timeline interfaces, which tend to not scale well, and which do not illustrate important semantic relationships among the data. An improved technique would be useful in news analysis, social and historical research, ...

Timelines are a formalism to model planning domains where the temporal aspects are predominant, and have been used in many real-world applications. Despite their practical success, a major limitation is the inability to model temporal uncertainty, i.e. the fact that the plan executor cannot decide the actual duration of some activities. In this paper we make two key contributions. First, we pro...

Widespread use of social media has led to the generation of substantial amounts of information about individuals, including health-related information. Thus, social media provides the opportunity to study health-related information about selected population groups who may be of interest for a particular study. In this paper, we explore the possibility of utilizing social media data to perform t...
