Revisiting the notion of boundary object
Revue d'anthropologie des connaissances, 2009 The article revisits the original publication by Susan L. Star and James R. Griesemer (1989) which founded the notion of the boundary object to rethink the actor-network theory (ANT) from an ecological perspective of collective action and distributed ...

Situational object boundary detection [PDF]
2015 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2015 Intuitively, the appearance of true object boundaries varies from image to image. Hence the usual monolithic approach of training a single boundary predictor and applying it to all images regardless of their content is bound to be suboptimal. In this paper we therefore propose situational object boundary detection: We first define a variety of ...

The screenplay as boundary object [PDF]
Journal of Screenwriting, 2019 Described by Pasolini as a ‘structure that wants to be another structure’, the question of what kind of thing-in-itself the screenplay might be has produced a range of answers. Screenwriter Jean-Claude Carrière has used the metaphor of the chrysalis – of vital importance in the process of the caterpillar’s metamorphosis into a butterfly – but useless ...

Object-Based Boundary Properties
, 2013 While object-based image analysis specializes in using region features for object detection, it lacks the possibility to use border strength and local geometry, common in edge detection. We propose to enhance common object-based image representation with boundary features that measure strength and continuity.

A Boundary-Fragment-Model for Object Detection [PDF]
, 2006 The objective of this work is the detection of object classes, such as airplanes or horses. Instead of using a model based on salient image fragments, we show that object class detection is also possible using only the object's boundary. To this end, we develop a novel learning technique to extract class-discriminative boundary fragments.

Weakly Supervised Object Boundaries [PDF]
2016 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2016 State-of-the-art learning based boundary detection methods require extensive training data. Since labelling object boundaries is one of the most expensive types of annotations, there is a need to relax the requirement to carefully annotate images to make both the training more affordable and to extend the amount of training data.

The objective stance and the boundary problem [PDF]
European Journal of Philosophy, 2021 AbstractThis paper investigates some unexplored ambivalences of Strawson's distinction between the participant stance marked by reactive attitudes and the objective stance in which such attitudes are deemed inappropriate. First, a distinction between recipient‐oriented and agent‐oriented reasons for taking the objective stance is introduced.

Boundary objects in information science
Journal of the Association for Information Science and Technology, 2017 Boundary objects (BOs) are abstract or physical artifacts that exist in the liminal spaces between adjacent communities of people. The theory of BOs was originally introduced by Star and Griesemer in a study on information practices at the Berkeley Museum of Vertebrate Zoology but has since been adapted in a broad range of research contexts in a large ...

De l’objet intermédiaire à l’objet-frontière
Revue d'anthropologie des connaissances, 2011 The paper intends to reconsider the concept of intermediary object, sometimes confused with boundary-border. After the presentation of the context of the formation of this concept and the knowledge issues aimed initially within the framework of the ...
