Representing structured events as vectors in continuous space offers a new way for defining dense features for natural language processing (NLP) applications. Prior work has proposed effective methods to learn event representations that can capture syntactic and semantic information over text corpus, demonstrating their effectiveness for downstream tasks such as event-driven stock prediction. O...

A fully generative model is provided for the problem of author disambiguation. This approach infers the topics for each author and combines that with co-author information. The problems involved are similar to other entity resolution problems where differing references may refer to one author entity and identical references may refer to different author entities. We extend the hierarchical Diri...

In the present study, we investigate if speakers refer to moving entities in route directions (RDs) and how listeners evaluate these references. There is a general agreement that landmarks should be perceptually salient and stable objects. Animated movement attracts visual attention, making entities salient. We ask speakers to watch videos of crossroads and give RDs to listeners, who in turn ha...

Today’s search engines provide instant keyword-based auto-suggestion and completion of the user’s search queries. This paper presents a novel auto-suggestion interface for the Semantic Multimedia Explorer (SEMEX), a semantic search engine that supports entity-based exploratory video retrieval. In difference to traditional textbased retrieval, auto-suggestion and auto-completion of the user’s qu...

Entities Chris Swoyer Penultimate draft of a paper for Contemporary Debates in Metaphysics, eds., Theodore Sider, John Hawthorne, and Dean W. Zimmerman, Blackwell, 2008; pp 1-31. One of the most puzzling topics for newcomers to metaphysics is the debate over the existence and nature of abstract entities, things like numbers (seven), sets (the set of even numbers), properties (triangularity), an...
