Despite a clear improvement of search and retrieval temporal applications, current search engines are still mostly unaware of the temporal dimension. Indeed, in most cases, systems are limited to offering the user the chance to restrict the search to a particular time period or to simply rely on an explicitly specified time span. If the user is not explicit in his/her search intents (e.g., “philip seymour hoffman”) search engines may likely fail to present an overall historic perspective of the topic. In most such cases, they are limited to retrieving the most recent results. One possible solution to this shortcoming is to understand the different time periods of the query. In this context, most state-of-the-art methodologies consider any occurrence of temporal expressions in web documents and other web data as equally relevant to an implicit time sensitive query. To approach this problem in a more adequate manner, we propose in this paper the detection of relevant temporal expressions to the query. Unlike previous metadata and query log-based approaches, we show how to achieve this goal based on information extracted from document content. However, instead of simply focusing on the detection of the most obvious date we are also interested in retrieving the set of dates that are relevant to the query. Towards this goal, we define a general similarity measure that makes use of co-occurrences of words and years based on corpus statistics and a classification methodology that is able to identify the set of top relevant dates for a given implicit time sensitive query, while filtering out the non-relevant ones. Through extensive experimental evaluation, we mean to demonstrate that our approach offers promising results in the field of temporal information retrieval (T-IR), as demonstrated by the experiments conducted over several baselines on web corpora collections.  相似文献   

Writing histories for late-medieval objects: The engagement of conservation with theoretical perspectives on material culture     

Noëlle L.W. Streeton 《文物保护研究》2017,62(7):419-431

The current discipline of conservation lacks a satisfactory theoretical and methodological framework to guide historical writing beyond scientific methods. To address this gap, this paper evaluates disciplinary shortcomings and proposes a solution for a project based in Oslo that takes advantage of disciplinary strengths. The solution involves the adaptation of a robust critical approach that is closely aligned with post-processualism in archaeology, which notably engages with theoretical perspectives on material culture. The framework offers guidance for arguments developed around physical transformations of late-medieval liturgical objects and the circumstances (physical, environmental, and socio-political) that continually define and re-define their meanings. The themes chosen for the project set this research at the cross-roads between conservation and material culture studies, with investigations directed towards tangible and intangible transformations, or phases in the ‘lives’ of objects that pre-date the Reformation but are now held in museums.  相似文献   

The breadth of peer relationships among preschoolers: an application of the Q-connectivity method to externalizing behavior     

Hanish LD  Martin CL  Fabes RA  Barcelo H 《Child development》2008,79(4):1119-1136

Preschoolers' (M(age) = 48.7 months) social breadth (the number of peer children interact with and the frequency of these interactions) and the relations between breadth and externalizing behaviors were examined using the Q-connectivity method. After considering age, sex, and classroom effects on social breadth, children's externalizing behaviors were studied in relation to levels of social breadth across variations in frequency of exposure to peers and to patterns of decline in social breadth. Externalizing preschoolers occasionally interacted with most of their classmates. However, their individual peer networks moderately to rapidly became selective, and they engaged in repeated interactions with a relatively small number of peers. Although there were no sex effects, significant age and classroom effects were obtained.  相似文献   

Learning and Teaching in Uncertain Times: A Nietzschean Approach in Professional Higher Education     

Henriëtta Joosten 《Journal of Philosophy of Education》2013,47(4):548-563

Today professionals have to deal with more uncertainties in their field than before. We live in complex and rapidly changing environments. The British philosopher Ronald Barnett adds the term ‘supercomplexity’ to highlight the fact that ‘we can no longer be sure how even to describe the world that faces us’ (Barnett, 2004). Uncertainty is, nevertheless, not a highly appreciated notion. An obvious response to uncertainty is to reduce it—or even better, to wipe it away. The assumption of this approach is that uncertainty has no advantages. This assumption is, however, not correct as several contemporary authors have argued. Rather than problematising uncertainty, I will investigate the pros and cons of embedding uncertainty in educational practice of professional higher education. In order to thoroughly explore the probabilities and challenges that uncertainty poses in education, I will dwell on the radical ideas on uncertainty of the German philosopher Friedrich Nietzsche. In The Birth of Tragedy (1872) he recognises two forces: the Apollinian, that is the pursuit of order and coherence, and the Dionysian, that is the human tendency to nullify all systematisation and idealisation. Uncertainty is part of the Dionysian. I will argue that when educators take Nietzsche's plea to make room for the Dionysian to heart, they can better prepare students for an uncertain world. If, and only if, students are encouraged to deploy both tendencies—the Apollinian and the Dionysian—they can become professionals who are able to stand their ground in an uncertain and changing (professional) world.  相似文献   

The Application of Both-Ways and Two-Eyed Seeing Pedagogy: Reflections on Engaging and Teaching Science to Post-secondary Indigenous Students     

Michael Michie  Michelle Hogue  Joël Rioux 《Research in Science Education》2018,48(6):1205-1220

The issue of Indigenous engagement, participation and success in the sciences is a concern both in Australia and in Canada. The authors of this paper have taught Indigenous students in tertiary enabling programs, undergraduate science and science education. Their experiences bridging Indigenous and Western cultures in science and science education through Both-Ways (BW) or Two-Eyed Seeing (TES) pedagogical and methodological approaches form the data for this paper. Their teaching experience with tertiary level Indigenous students using BW/TES pedagogies serves as case studies for the epistemic insight (knowledge about knowledge) they have gained. Each of the case studies considers the role of the Nature of Science (NOS) and potential conflicts through engagement with the two knowledge paradigms. Rather than being in conflict, the two worldviews are seen as complementary, a situation leading to epistemic insight.  相似文献

Are implicit learning abilities sensitive to the type of material to be processed? Study on typical readers and children with dyslexia     

Aurélie Simoës Perlant  Pierre Largy 《Journal of Research in Reading》2011,34(3):298-314

This study aims to examine the impact of the linguistic nature of the material to be tracked in a serial reaction time task on the performance of typical readers and children with dyslexia. In doing so, we wished to detect eventual differences in the mobilisation of implicit learning skills between typical readers according to their experience with the written word (8‐ vs 10‐year‐olds) on the one hand, and between typical readers and children with dyslexia, on the other hand. Experiment 1 confirms the efficiency of implicit sequence learning in typical readers regardless of the nature of the item being tracked. Experiment 2 indicates that the sequence learning of children with dyslexia is sensitive to the nature of the target. Children with dyslexia show differences in the evolution of response times according to the nature of the item to be tracked.  相似文献
