This paper explores the task of creating a timeline for historical Wikipedia articles, such as those describing wars, battles, and invasions. It focuses on extracting only the major events from the article, particularly those associated with an absolute date. Existing tools extract all possible events, while we write tools to identify time expressions and anchor them in real time. From this set...

Planning is a core field of Artificial Intelligence since its beginnings. Broadly speaking, planning techniques aim at providing artificial agents with the capability to autonomously solve ”complex” problems. Several planning techniques have been introduced in the literature that employ different approaches for modeling and solving planning problems. My PhD research activities concern timeline-...

The Ross-Macdonald Model We use the following simple version of the Ross-Macdonald model. The parameters are described in Box #1. For a longer explanation, see [1]. The change in the PR, the prevalence of infection, is given by the equation: ˙ X = mabZ(1 − X) − rX (1) The change in the sporozoite rate, the fraction of the mosquitoes with sporozoites in their salivary glands, is modeled using th...

Retrospective analysis of agile projects can support identification of issues through team reflection and may enable learning and process improvements. Basing retrospectives primarily on experiences poses a risk of memory bias as people may remember events differently, which can lead to incorrect conclusions. This bias is enhanced in project retrospectives which cover a longer period compared t...

In this paper we study a problem of determining when entities are active based on their interactions with each other. More formally, we consider a set of entities V and a sequence of time-stamped edges E among the entities. Each edge (u, v, t) ∈ E denotes an interaction between entities u and v that takes place at time t. We view this input as a temporal network. We then assume a simple activit...

Consultations by patients requesting influenza vaccinations were monitored in nine group practices before and after a radio broadcast encouraging patients at risk to seek vaccination. In a population of over 88,000 patients 88 consulted about influenza vaccination prior to the broadcast and 52 after. Not one consulted for vaccination as a result of the broadcast. The implications of this are di...

the only available vaccine against tuberculosis is bcg which has been found to protect children against disseminated tuberculosis and tuberculous meningitis. bcg is one of the safest vaccines being used, and osteitis is a rare complication of it. during a period of eight years, we had eleven cases of osteitis occuring in infants following bcg vaccination. eight cases were female. defect in immu...
