This paper uses materials from annotation studies of lexical cohesion (Beigman Klebanov and Shamir, 2005) and of definite reference (Poesio and Vieira, 1998; Vieira, 1998) to discuss the complementary nature of the two processes. Juxtaposing the two kinds of annotation provides a unique perspective for observing the workings of the reader’s common-sense knowledge at two levels of text organizat...

Relevant events in a three state illness-death model (IDM) of a chronic disease are the diagnosis of the disease and death with or without the disease. In this article a simulation framework for populations moving in the IDM is presented. The simulation is closely related to the concept of Lexis diagrams in event history analysis. Details of the implementation and an example of a hypothetical d...

In this paper we address the problem of filtering obscene lexis in Russian texts. We use string similarity measures to find words similar or identical to words from a stop list and establish both a test collection and a baseline for the task. Our experiments show that a novel string similarity measure based on the notion of an annotated suffix tree outperforms some of the other well known measu...
