From X-Rays to Silly Putty via Uranus: Serendipity and its Role in Web Search
No full textThe act of encountering information unexpectedly has long been identified as valuable, both as a joy in itself and as part of task-focused problem solving. There has been a concern that highly accurate search engines and targeted personalization may reduce opportunities for serendipity on the Web. We examine whether there is the potential for serendipitous encounters during Web search, and whether improving search relevance through personalization reduces this potential. By studying Web search query logs and the results people judge relevant and interesting, we find many of the queries people perform return interesting (potentially serendipitous) results that are not directly relevant. Rather than harming serendipity, personalization appears to identify interesting results in addition to relevant ones
Discovery Is Never By Chance: Designing for (Un)Serendipity
No full textSerendipity has a long tradition in the history of science as having played a key role in many significant discoveries. Computer scientists, valuing the role of serendipity in discovery, have attempted to design systems that encourage serendipity. However, that research has focused primarily on only one aspect of serendipity: that of chance encounters. In reality, for serendipity to be valuable chance encounters must be synthesized into insight. In this paper we show, through a formal consideration of serendipity and analysis of how various systems have seized on attributes of interpreting serendipity, that there is a richer space for design to support serendipitous creativity, innovation and discovery than has been tapped to date. We discuss how ideas might be encoded to be shared or discovered by ‘association-hunting’ agents. We propose considering not only the inventor’s role in perceiving serendipity, but also how that inventor’s perception may be enhanced to increase the opportunity for serendipity. We explore the role of environment and how we can better enable serendipitous discoveries to find a home more readily and immediately
Enhancing Performance in Latent Semantic Indexing (LSI) Retrieval
No full textWe have previously described an extension of the vector retrieval method called "Latent Semantic Indexing" (LSI) (Deerwester, et al., 1990; Dumais, et al., 1988; Furnas, et al., 1988). The LSI approach partially overcomes the problem of variability in human word choice by automatically organizing objects into a "semantic" structure more appropriate for information retrieval. This is done by modeling the implicit higher-order structure in the association of terms with objects. Initial tests find this completely automatic method to be a promising way to improve users' access to many kinds of textual materials or to objects for which textual descriptions are available. This paper describes some enhancements to the basic LSI method, including differential term weighting and relevance feedback. Appropriate term weighting improves performance by an average of 40%, and feedback based on 3 relevant documents improves performance by an average of 67%. September 1, 1992 D R A F T Dumais - 2 1...

La fonction de l’art dans la théologie féministe de Monique Dumais
No full textUne des pionnières de la théologie féministe universitaire au Québec, Monique Dumais (1939-2017), a également été une passionnée des arts, critique de maintes performances, mais aussi actrice et productrice, particulièrement de poésie, de théâtre et de littérature. L’objectif de cet article est de présenter une synthèse des éléments-clés de sa théologie féministe sous l’angle de la fonction qu’y a occupée l’art. L’étude présente successivement ses créations conceptuelles et ses créations artistiques, pour ensuite construire des liens entre elles. Une idée force du féminisme chrétien de Monique Dumais est qu’en christianisme, l’on manque d’incarnation. La Pâque des femmes, ce passage de la domination à la libération, repose sur l’intégration de leurs expériences féministes dans une créativité et dans une incarnation en acte de leur corps et de leur souffle. Ce mouvement vital excède les concepts. Les arts, qui appartiennent au domaine des sensations, y suppléent pour briser les logiques patriarcales.One of the pioneers of academic feminist theology in Quebec, Monique Dumais (1939-2017) was also fascinated by arts. As such she has been a performing arts critic, as well as an author and a producer, especially in poetry, theater and literature. This paper is to shortly present key elements of her feminist theology with a focus on the place that art plays in it. This study will successively detail her conceptual and artistic creations to find some links between them. One of the main contentions of Monique Dumais’ Christian feminism is that there is a lack of incarnation in Christianity. Women’s Easter, this passage from domination to liberation, is based on integrating women’s experiences in creativity and in an incarnation in acts of their bodies and their breaths. This vital movement surpasses concepts. Arts, which are from the domain of sensations, help breaking patriarchal logics
