Journal and digital library portals are the information systems that researchers turn to most frequently for undertaking and disseminating their academic work. However their interfaces have not been improved. We propose an articulation of the navigation and search systems in a single visual solution that would allow the simultaneous exploration and...

This paper presents a review of approaches to text visualization and exploration. Text visualization and exploration, we argue, constitute a subfield of data visualization, and are fuelled by the advances being made in text analysis research and by the growing amount of accessible data in text format. We propose an original classification for a tot...

We present Crossreads, a manner to deconstruct linear narrative text in order to read text in multiple orders. This is an ongoing project aims to study data multiplicity, as well as textual visualization interfaces. The process starts with the selection of a text, which is later segmented into small blocks, and the textual similarity among them is...

Introduction. The presentation of the results page in a search system plays an important role in satisfying the information needs of a user. The usual performance management criteria and tools to organise results have limitations that may hinder the satisfaction of those needs. We present Texty as a new approach that can help improve the search exp...

[Audio disponible en: https://www.museoreinasofia.es/multimedia/documentos-10-archivo-mariategui]. El programa del Museo Reina Sofía Documentos versa sobre publicaciones de artista, plataformas, redes y espacios editoriales de circulación independiente, así como sobre el potencial del archivo para reinventar las narraciones acerca del arte y su eco...

Clarity of language improves efficiency and reduces misunderstanding. In written text, it is measured by readability and with patent documents , this readability is known to be particularly poor in the case of layperson-users without specialized knowledge in this subject. Here we introduce a 46-question survey, founded socio-technical theories of i...

This work introduces Diggersdiaries, an web interface to a historical textual document collection. Digital collections are rich in content, but traditional search-based and faceted-based interfaces cannot represent their richness efficiently - e.g. for time-poor and casual browsing. This project addresses this challenge using data analysis (topic m...

This research brings together data analysis with software engineering and visualisation, with a specific focus on text mining and large document collections. My aim is to devise new, rich, and simple visualisation interfaces, which I call deep interfaces. With deep interfaces I introduce the idea-rich content as a product of the statistical analys...

The analysis and exploration of dynamic spatio-temporal data presents particular challenges. The VAST 2016 contest provided the opportunity to explore solutions in this space, focusing on the identification of patterns and anomalies. In this paper, we present an approach based on element-level references that allows for the exploration of individua...

This research project aims to improve the way humans work with textual documents when doing tasks such as exploring, discovering, searching, filtering, collecting, indexing, comparing, or just reading. This research project studies theoretical foundations and practical uses of text visualization techniques. As a contribution to theory, the research...

Discharge summaries serve a variety of aims, ranging from clinical care to legal purposes. They are also important tools in patient empowerment, but a patient’s comprehension of the information is often suboptimal. Continuing in the tradition of focusing on automated approaches to increasing patient comprehension, The CLEFeHealth2014 lab tasked par...
