Querytogether: Enabling entity-centric exploration in multi-device collaborative search

Collaborative and co-located information access is becoming increasingly common. However, fairly little attention has been devoted to the design of ubiquitous computing approaches for spontaneous exploration of large information spaces enabling co-located collaboration. We investigate whether an entity-based user interface provides a solution to support co-located search on heterogeneous devices. We present the design and implementation of QueryTogether, a multi-device collaborative search tool through which entities such as people, documents, and keywords can be used to compose queries that can be shared to a public screen or specific users with easy touch enabled interaction. We conducted mixed-methods user experiments with twenty seven participants (nine groups of three people), to compare the collaborative search with QueryTogether to a baseline adopting established search and collaboration interfaces. Results show that QueryTogether led to more balanced contribution and search engagement. While the overall s-recall in search was similar, in the QueryTogether condition participants found most of the relevant results earlier in the tasks, and for more than half of the queries avoided text entry by manipulating recommended entities. The video analysis demonstrated a more consistent common ground through increased attention to the common screen, and more transitions between collaboration styles. Therefore, this provided a better fit for the spontaneity of ubiquitous scenarios. QueryTogether and the corresponding study demonstrate the importance of entity based interfaces to improve collaboration by facilitating balanced participation, flexibility of collaboration styles and social processing of search entities across conversation and devices. The findings promote a vision of collaborative search support in spontaneous and ubiquitous multi-device settings, and better linking of conversation objects to searchable entities.     

Learning literacy though play using interactive texts during storybook reading: A parent/child experience

Abstract

Based on first hand field notes, I undertook to research the reasons why children interacted or did not interact appropriately with a common emergent literacy experience, the readaloud. I explored the reasons why par‐ents/caregivers may not effectively participate in storybook reading, including reactions of parents/caregivers during four literacy events. I determined that the key to successful literacy experiences were first hand, personal involvement of the children in an active learning experience associated with interactive texts. Here, children were invited to create appropriate actions to accompany the story readings. Interactive texts appear to hold the key to successful early literacy experiences for preschoolers. © 2005 Published by Elsevier Inc.     

Codified-tacit and general-specific knowledge in the division of labour among firms: A study of the software industry

This paper explores the organisation and codification of knowledge in software firms. It analyses various economic incentives to codification, including the need to improve the productivity and quality of software production and the networks of inter-firm alliances.The paper examines the experience of five Italian software firms specialising in software packages and services. It compares their capabilities, main sources of tacit knowledge, specific incentives to invest in knowledge codification and the formal development methodologies and quality control systems adopted. Finally, the paper analyses two distinct technological collaborations that two of these firms have recently established.
