Inverted Index Compression Using Word-Aligned Binary Codes 总被引：3，自引：1，他引：3
We examine index representation techniques for document-based inverted files, and present a mechanism for compressing them using word-aligned binary codes. The new approach allows extremely fast decoding of inverted lists during query processing, while providing compression rates better than other high-throughput representations. Results are given for several large text collections in support of these claims, both for compression effectiveness and query efficiency. 相似文献

激进女性主义将运动中性别不平等的根源视为父权制的结果。激进女性主义在体育领域对父权制的批判，主要集中在父权制暗含的男性身体优越性、父权制下的体育权力机构以及女性体育的男性中心取向等3个方面。激进女性主义认为，性别气质是社会建构的结果，并且可以通过运动予以解构和重建；女性对男性传统体育项目的参与挑战了传统的性别理解，同时，男性参与女性传统项目对于其人格的完整发展也是有益的。从本质上讲，激进女性主义所运用的是一种文化分析的方法，其力图通过对运动意义和流行方式的重新界定来实现实质性的性别平等。 相似文献

Five hundred million tweets are posted daily, making Twitter a major social media platform from which topical information on events can be extracted. These events are represented by three main dimensions: time, location and entity-related information. The focus of this paper is location, which is an essential dimension for geo-spatial applications, either when helping rescue operations during a disaster or when used for contextual recommendations. While the first type of application needs high recall, the second is more precision-oriented. This paper studies the recall/precision trade-off, combining different methods to extract locations. In the context of short posts, applying tools that have been developed for natural language is not sufficient given the nature of tweets which are generally too short to be linguistically correct. Also bearing in mind the high number of posts that need to be handled, we hypothesize that predicting whether a post contains a location or not could make the location extractors more focused and thus more effective. We introduce a model to predict whether a tweet contains a location or not and show that location prediction is a useful pre-processing step for location extraction. We define a number of new tweet features and we conduct an intensive evaluation. Our findings are that (1) combining existing location extraction tools is effective for precision-oriented or recall-oriented results, (2) enriching tweet representation is effective for predicting whether a tweet contains a location or not, (3) words appearing in a geography gazetteer and the occurrence of a preposition just before a proper noun are the two most important features for predicting the occurrence of a location in tweets, and (4) the accuracy of location extraction improves when it is possible to predict that there is a location in a tweet. 相似文献

A multifaceted, relationally focused intervention involving group and individual pre- and postnatal counseling, print resources, and community resources encouraged 390 fathers of newborn infants in Vietnam to responsively support mothers and work with them as a parenting team. Both partners completed questionnaires prebirth and 1-, 4-, and 9-months postbirth on measures of breastfeeding support, exclusive breastfeeding duration, relationship quality, and infant development. Compared to 412 comparison group couples, intervention couples evidenced greater father support, especially in terms of helping and responsiveness to the mother's needs. This support predicted longer exclusive breastfeeding duration, improved relationship quality, and higher levels of infant development at 9 months. Sensitively working together with mothers as a coordinated team enhanced couple's relationship functioning and improved children's developmental outcomes. 相似文献

Abstract The Vietnamese Women’s Museum (VWM) opened in 1995 with the mission to improve public knowledge of the historical and cultural heritage of Vietnamese women in the nation’s 54 ethnic community groups. The VWM aimed to be a center for cultural exchange with women from other nations with the goal of fostering “equality, development, and peace.” At the outset it honored the positive role played by women in general, and presented some typical individuals acclaimed for their contributions and sacrifices. After some visitor research, the museum is now using a gender‐specific approach, playing the role of social critic, reflecting contemporary life, and targeting marginalized women groups. 相似文献

The number of contact hours, one of the important institutional context factors, was examined and compared between Dutch and
Vietnamese higher education at institute and student levels in Psychology and Business and/or Economics specializations. The
quantity of contact hours per credit point given by institutions was investigated in a number of Dutch and Vietnamese universities.
Additionally, 104 students in Groningen, the Netherlands, and 140 students in Hanoi and Ho Chi Minh City, Vietnam, participated
in the survey with a self-reported and self-assessed questionnaire on their study time allocation. Beside contact hours, other
learning process related factors such as study activities, motivation, quality of instruction, and generic skills were examined
to provide a better insight into these two systems. Results showed that Vietnamese students had significantly higher number
of contact hours than Dutch students while their generic skills, motivation and time spent on independent study were a lot
lower. 相似文献

Given the growing importance of online social media platforms (OSM) in brand management, the authors attempt to extend the relationship between e-brand equity and repurchase intention with two mediator variables, namely visual appeal and e-preference in which willingness to pay a price premium (WPPP) serves as a moderator. Drawing on the perspective of digitalized engagement (PDE), the authors confirm the mediating effects on the e-brand equity-repurchase intention link while evidencing both positive and negative effects of WPPP on the linkage of e-brand equity and mediators. Contributions to theory, practice, and future studies are also provided. 相似文献
