10491 Results of the break-out group: Gulls Data
No full textA classification of gull behaviour was produced by the group, led by domain
expert Emiel van Loon, who provided additional context including that gull trips
are typically composed of distinct segments, that gull trips are rarely single
purpose, and that there is very little diurnal pattern to activities. The
classification produced is not intended to be complete, or non overlapping.
Furthermore, the group considered how the attributes in the gulls dataset could be used in algorithms to automatically classify the dataset into distinct spatial
patterns, and associate this with gull behaviours

Representation, Analysis and Visualization of Moving Objects (Dagstuhl Seminar 12512)
Full text linkFrom December 16 to December 21, 2012, the Dagstuhl Seminar 12512 "Representation, Analysis and Visualization of Moving Objects" was held in Schloss Dagstuhl -- Leibniz Center for Informatics. The major goal of this seminar was to bring together the diverse and fast growing, research community that is involved in developing better computational techniques for spatio-temporal object representation, data mining, and visualization of moving object data. The participants included experts from fields such as computational geometry, data mining, visual analytics, GIS science, urban planning and movement ecology. Most of the participants came from academic institutions but some also from government agencies and industry. The seminar has led to a fruitful exchange of ideas between different disciplines, to the creation of new interdisciplinary collaborations and to recommendations for future research directions. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper
10491 Results of the break-out group: Benchmarking
No full textThis working group has discussed the possibilities to start developing benchmarking tools for algorithms to analyse movement data. Many basic properties of movement data and derived products from these data are not clearly defined. In addition, analysis algorithms vary with respect to input as well as output data. As a result, it is difficult to evaluate the suitability of different algorithms for application to a given type of data and question. We think there is a need to define clear tests or experiments for this purpose
Human Foraging Experiment Dataset
No full textChimpanzees are our closest living relatives and have been extensively used in research into the evolution of humans. Although chimpanzees and humans share many of the same cognitive abilities, how they compare in solving spatial tasks is unclear to date. Therefore this study conducted a human physical simulation method that resembles foraging patterns of chimpanzees to enable comparing these spatiotemporal cognitive abilities. Furthermore, this study aimed to interpret animal movement and spatiotemporal cognitive abilities by relating revisit intervals to cognitive processes such as learning and memory. For this, two variables, constancy and contingency, have been used to reflect search efficiency, and their values were used to make inferences about the cognitive abilities of humans and chimpanzees. Ultimately, this study investigated how the average patterns in revisit constancy and contingency relate to the spatiotemporal cognitive abilities of chimpanzees, and how this compares to those of humans. These results are highly valuable in addressing the aforementioned existing knowledge gaps, but the novel stimulation method additionally provides a great perspective for future research into animal movement. This dataset contains the data obtained from the human foraging experiment that was conducted for the Bachelor's thesis: "Assessing the Use of Recursive Movement Data to Reflect Spatiotemporal Cognitive Abilities: Comparing Spatiotemporal Intelligence of Humans and Chimpanzees"
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
