In this paper we present the system we have developed for our participation in the annual TRECVid benchmarking activity, specifically the system we have developed, Fı́schlár-DT, for participation in the interactive search task of TRECVid 2005. Our back-end search engine uses a combination of a text search which operates over the automatic speech recognised text, and an image search which uses lo...

In this position paper we describe how visual analysis of heterogeneous text data is likely to benefit large-scale collaborative engineering projects. We describe use cases and tasks performed by project managers, which are potential targets for visual text analysis. We also discuss our objective to develop a structured visualization design process that will enable relevant and insightful heter...

The Boeing Collaborative Document Reviewer is an enterprise web application supporting large scale asynchronous collaborative authoring through real-time shared commenting. The application is specifically targeted to supporting the review and critique of contractor draft product documents by United States government customers. The system supports an iterative In-Process Review (IPR) workflow wi...

Unlike research in reading which focuses on data from individuals reading independently, this study identified second language (L2) college students’ reading processes that occurred within dyadic peer interactions during shadow-reading, a collaborative procedure based on repetition and summarizing. Also, written retellings (immediate and delayed) were collected to assess the impact of shadow-re...

This chapter presents a tool for collaborative elearning using handheld devices that incorporates pair communication via text and speech input. It discusses the current state of e-learning for mobiles and illustrates the lack of such tools in reading comprehension domains. It then describes the tool development as a model for interface design, communication strategies, and data manipulation acr...

This paper describes an approach for network text analysis and visualization for collaboratively edited documents. It incorporates network extraction from texts where nodes represent concepts identified from the words in the text and the edges represent relations between the concepts. The visualization of the concept networks depicts the general structure of the underlying text in a compact way...

This paper presents a system for computer-aided thinking. We propose the idea of reflecting the mental world indirectly into a metric space to support such human thinking activities as externalizing and forming new ideas. We use a method that maps text-objects into metric spaces for visualizing a user’s thought space structure. Text-objects imply fragments of a user’s idea, which have several k...

Collaborative tagging is the process whereby people attach keywords, known as tags, to digital resources, such as text and images, in order to render them retrievable in the future. This thesis investigates how tags submitted by users in collaborative tagging systems function as descriptors of a resource’s perceived content. Using computational and theoretical tools, I compare collaborative tag...

In this article we describe the emerging area of text classification research focused on the problem of collaborative learning process analysis both from a broad perspective and more specifically in terms of a publicly available tool set called TagHelper tools. Analyzing the variety of pedagogically valuable facets of learners’ interactions is a time consuming and effortful process. Improving a...
