The processing of intellectual property documents, such as patents, has been important to the industry, business, and law communities. Recently, the importance of patent processing has also been recognized in academic research communities, particularly by information retrieval and natural language processing researchers. In addition, large test collections that include patents have recently become available, to enable the systematic evaluation of methodologies from a scientific point of view. In the light of these activities, this special issue is intended to collect advanced research papers on patent processing. As an introduction to the special issue on patent processing, this paper surveys the relevant literature and outlines the papers selected for the special issue. 相似文献

While there is a great demand to share training programs globally, there are few methodologies to implement effective instructional development processes in multicultural organizations. Based on lessons learned from a Fortune 500 company, this article presents an instructional development model for global organizations. Three main gaps are identified in a practice of instructional design (ID) model for international settings: language, culture, and needs gaps at local sites. In order to solve these problems, the proposed model includes a decentralized process and collaborative efforts between the originating site and local sites. The virtues of the proposed model are just-in-time training, flexibility, and adequateness. The current situations in global organizations are ill-structured and require the sharing of multiple perspectives through collaboration in order to accomplish social consensus. The characteristics in the presently proposed model are that a) there is limited predetermined content, b) there is a sharing of multiple perspectives, c) there is needs negotiation, and d) learning is occurring within a context. 相似文献

This article describes three studies that examined Japanese children’s and adults’ intuitive perceptions regarding the links between pain, effort, and healing. A total of 79 six-year-olds, 81 nine-year-olds, 74 twelve-year-olds, and 66 adults were presented with scenarios involving modern and traditional medical interventions and were examined with regard to how the level of pain and effort presented in the scenarios influenced their views of healing. It was consequently found that the 6-year-olds tended to judge painful interventions as aversive, while adults considered them to be effective. Furthermore, overall, effortful interventions were believed to be more efficacious than painful ones. The children and adults appeared to assume that people who have tried hard and expended considerable effort deserve to be healed quickly. These results are in accord with the coexistence model, which posits that an individual can have coexisting scientific and folk beliefs across his/her life course. 相似文献

The application of word sense disambiguation (WSD) techniques to information retrieval (IR) has yet to provide convincing retrieval results. Major obstacles to effective WSD in IR include coverage and granularity problems of word sense inventories, sparsity of document context, and limited information provided by short queries. In this paper, to alleviate these issues, we propose the construction of latent context models for terms using latent Dirichlet allocation. We propose building one latent context per word, using a well principled representation of local context based on word features. In particular, context words are weighted using a decaying function according to their distance to the target word, which is learnt from data in an unsupervised manner. The resulting latent features are used to discriminate word contexts, so as to constrict query’s semantic scope. Consistent and substantial improvements, including on difficult queries, are observed on TREC test collections, and the techniques combines well with blind relevance feedback. Compared to traditional topic modeling, WSD and positional indexing techniques, the proposed retrieval model is more effective and scales well on large-scale collections. 相似文献

On information retrieval metrics designed for evaluation with incomplete relevance assessments 总被引：1，自引：0，他引：1
Modern information retrieval (IR) test collections have grown in size, but the available manpower for relevance assessments
has more or less remained constant. Hence, how to reliably evaluate and compare IR systems using incomplete relevance data, where many documents exist that were never examined by the relevance assessors, is receiving a lot of attention.
This article compares the robustness of IR metrics to incomplete relevance assessments, using four different sets of graded-relevance
test collections with submitted runs—the TREC 2003 and 2004 robust track data and the NTCIR-6 Japanese and Chinese IR data
from the crosslingual task. Following previous work, we artificially reduce the original relevance data to simulate IR evaluation
environments with extremely incomplete relevance data. We then investigate the effect of this reduction on discriminative power, which we define as the proportion of system pairs with a statistically significant difference for a given probability of
Type I Error, and on Kendall’s rank correlation, which reflects the overall resemblance of two system rankings according to two different metrics or two different relevance
data sets. According to these experiments, Q′, nDCG′ and AP′ proposed by Sakai are superior to bpref proposed by Buckley and
Voorhees and to Rank-Biased Precision proposed by Moffat and Zobel. We also point out some weaknesses of bpref and Rank-Biased
Precision by examining their formal definitions.

This study aimed to evaluate changes in the attitudes of Japan’s post-war youth towards gender equality and sexuality, and to examine whether these attitudes bore a relationship to school education. Different generations were delineated based on changes in courses of study and year of birth, and semi-structured interviews were conducted enquiring about experiences and opinions during secondary school days. We examined sexuality education in both junior high school (ages 12–15 years) and high school (15–18 years), views on premarital sex, views on marriage and divorce, and views on gender roles. Fifty-three survey participants were involved in the study: 30 women and 23 men. The characteristics of each generation were examined in relation to corresponding courses of study and the textbooks available in junior high and high schools, identifying both homologies and differences between the messages courses contained and the expressed beliefs of different generations of informants. 相似文献
