《艺概·赋概》研究综述

《艺概·赋概》是晚期近代赋论中最为重要的成果。它内容丰富,论述简单明确,可以说是古典赋论的终结。文章从注释、批评史、赋学研究专著、学术论文四个方面,对从1935年开始到现在的《赋概》研究进行一个系统的梳理。相对来说,《赋概》一直是《艺概》研究中冷门的部分,它还没有引起人们的重视。综合讨论《赋概》的研究现状,不仅可以对前人的研究进行总结探讨,也可以对后来学者研究《赋概》提供参考。

An approach to web-based Personal Health Records filtering using fuzzy prototypes and data quality criteria

Nowadays, new ways of managing and accessing to health-care information are continuously appearing. Web-based Personal Health Records (web PHRs) have the potential to make data about health-care available to clinicians, researchers and students in different medical contexts and applications. Therefore, the amount of web PHRs accessible through Internet has grown enormously and as a result health-care professionals are currently burdened with more and more data. It’s probable that these data, unfortunately, have not always the adequate levels of quality, making that their work cannot always be as successful as expected. As a way of alleviating this fact, the present work is focused on improving the document filtering results in the context of web PHRs management. To achieve this goal, a new kind of document filtering model is proposed. This model is based on fuzzy prototypes which are defined by means of conceptual prototypes. These prototypes are obtained by using a data quality analysis of documents. This analysis guarantees that filtered information will be relevant enough for the information user. The complete model provides an efficient strategy of document filtering that can be very useful when it is necessary to deal with a constant flow of new information.     

A hybrid approach to managing job offers and candidates

The evolution of the job market has resulted in traditional methods of recruitment becoming insufficient. As it is now necessary to handle volumes of information (mostly in the form of free text) that are impossible to process manually, an analysis and assisted categorization are essential to address this issue. In this paper, we present a combination of the E-Gen and Cortex systems. E-Gen aims to perform analysis and categorization of job offers together with the responses given by the candidates. E-Gen system strategy is based on vectorial and probabilistic models to solve the problem of profiling applications according to a specific job offer. Cortex is a statistical automatic summarization system. In this work, E-Gen uses Cortex as a powerful filter to eliminate irrelevant information contained in candidate answers. Our main objective is to develop a system to assist a recruitment consultant and the results obtained by the proposed combination surpass those of E-Gen in standalone mode on this task.     

基于名实体的新闻专题自动综述系统研究与实现

自动综述是指针对特定的主题进行多文档自动摘要,最终提供简洁、重要的信息.新闻专题自动综述是多文档自动摘要的一种应用形式,它可以帮助人们快速了解某个新闻事件的概貌.提出了一种基于名实体的新闻专题自动综述方法.该方法首先从新闻专题的文章集合中识别并挑选出代表新闻要素的时间、地点、人物、机构等名实体,经过语义处理后进行名实体的频率统计.然后根据句子中名实体的频率,结合句子位置、长度等因素计算句子的综合权值选出摘要句,最后根据句子的时间戳信息对句子排序输出得到最终的新闻专题综述.实验结果表明,该方法是有效的,具有实用价值.
