Using ontologies as a faceted browsing for heterogeneous cultural heritage collections

In this paper we present a project regarding the possible use of multi- ple and interconnected OWL ontologies (GO!, HiCo, and Proles) in order to explore the semantic content of heterogeneous digital collections (a digital li- brary, a full-text scholarly edition, and a relational database) in the cultural her- itage domain (Geolat, Vespasiano da Bisticci Letters, and Zeri photo archive). The aim is to discover knowledge by revealing, through facets, possible latent connections \u2013 or even contradictory statements \u2013 between data, moving from person, places and dates in an event-centric dimension determined by a context- oriented perspective

Neogeography: The Challenge of Channelling Large and Ill-Behaved Data Streams

Neogeography is the combination of user generated data and experiences with mapping technologies. In this article we present a research project to extract valuable structured information with a geographic component from unstructured user generated text in wikis, forums, or SMSes. The extracted information should be integrated together to form a collective knowledge about certain domain. This structured information can be used further to help users from the same domain who want to get information using simple question answering system. The project intends to help workers communities in developing countries to share their knowledge, providing a simple and cheap way to contribute and get benefit using the available communication technology

A Quadruple-Based Text Analysis System for History and Philosophy of Science

abstract: Computational tools in the digital humanities often either work on the macro-scale, enabling researchers to analyze huge amounts of data, or on the micro-scale, supporting scholars in the interpretation and analysis of individual documents. The proposed research system that was developed in the context of this dissertation ("Quadriga System") works to bridge these two extremes by offering tools to support close reading and interpretation of texts, while at the same time providing a means for collaboration and data collection that could lead to analyses based on big datasets. In the field of history of science, researchers usually use unstructured data such as texts or images. To computationally analyze such data, it first has to be transformed into a machine-understandable format. The Quadriga System is based on the idea to represent texts as graphs of contextualized triples (or quadruples). Those graphs (or networks) can then be mathematically analyzed and visualized. This dissertation describes two projects that use the Quadriga System for the analysis and exploration of texts and the creation of social networks. Furthermore, a model for digital humanities education is proposed that brings together students from the humanities and computer science in order to develop user-oriented, innovative tools, methods, and infrastructures.Dissertation/ThesisDoctoral Dissertation Biology 201

An ontological approach to the study of European popular culture

Like any other field of contemporary scholarly research, the Humanities in general, and Cultural Studies in particular are today confronted with the challenges of complexity at an unprecedented scale. What has been described as the \u201castonishing growth\u201d of academic publications worldwide is paralleled by a similar proliferation of browsable online databases, like digital archives, collections and catalogues, which offer access to an immense and continuously increasing volume of virtually interesting research material, stored in the form of information bytes. As we discussed in Deliverable 2.1, \u201cSorting out the archive for the study of European popular culture\u201d, the problem of how to cope with such an unseizable of virtually relevant sources of evidence is all the more sensible in the case of a project like DETECt, which deals with one of the most prolific narrative genres of contemporary media production, that is, the European crime narrative genre. Not only an exhaustive catalogue of this production could easily count\u2014especially when considered in all of its transnational scope\u2014in thousands of thousands, and even\u2014in historical perspective\u2014millions of items, but the transdisciplinary scope of the studies it has inspired has produced a wealth of research in many domains of knowledge. These difficult challenges make DETECt an ideal laboratory for experimenting new methods to manage complexity in a transnational/transcultural research environment. This methodological experimentation aims to respond to the problem of how to generate effective syntheses of portions and/or aspects of a given knowledge domain in a context of information overload. To this purpose, the ontological approach chosen by DETECt focuses on the application of knowledge mapping techniques to encourage the formulation of partial knowledge syntheses within a \u201crealist\u201d, and even \u201cpragmatic\u201d theoretical framework

Position Tracking and GIS in Search and Rescue Operations

Geographical information systems can be useful in supporting an operational or situational picture in emergency situations. One particular use case is to keep track of moving personnel in the field. This has proven to be useful for safety (of rescue personnel), as well as for monitoring, planning and documentation of operations in the field. In this chapter, we define some concepts of tracking information, and tell the story how enthusiasts from the radio-amateur and red-cross communities developed and applied position tracking to search and rescue services in Norway. Based on years of experience from this work we discuss some issues related to how systems could deal with such spatiotemporal data in emergency and SAR situations

Can humain association norm evaluate latent semantic analysis?

This paper presents the comparison of word association norm created by a psycholinguistic experiment to association lists generated by algorithms operating on text corpora. We compare lists generated by Church and Hanks algorithm and lists generated by LSA algorithm. An argument is presented on how those automatically generated lists reflect real semantic relations
