Focused and aggregated search: a perspective from natural language generation   总被引：1，自引：0，他引：1

Users are often faced with complex information needs that are not easily represented as a single query. With current technology, the burden of issuing these individual queries, analysing retrieved documents for relevance, as well as aggregating results falls upon the time-poor and informationally overloaded user. Aggregated search techniques represent the new generation of search applications that endeavour to help users perform these complex tasks. However, the way in which different data types are combined in current aggregated search applications is often performed using static hard-coded structures. We suggest that a useful alternative is to marry techniques from natural language generation, such as text planning and summarisation, in order to dynamically determine the best organisation of retrieved information. These organisations can be motivated by linguistic theories that consider issues such as the role that the information plays to facilitate a task, and the relationships between different pieces of information. With reference to a discourse strategy, it is possible to draw on several data sources automatically to generate a useful, focused, and coherent answer. We focus on exploring the parallels between aggregated search and natural language generation in the hope that the fields can be mutually informed, leading to further advances in the way search technologies can better serve the user. These issues are discussed and presented with examples of existing systems across different domains.  相似文献

基于用户相关反馈的带结构语义的XML查询词扩展   总被引：1，自引：0，他引：1  

万常选  鲁远 《情报学报》2009,28(3)

在XML文档的信息检索中,检索质量不高的一个主要原因是用户难以提出准确描述其查询意图的查询表达式,而查询扩展技术被认为是可以帮助用户构建符合其查询意图的查询表达式.本文在XML信息检索中提出了基于用户相关反馈的查询扩展技术,在查询扩展中除了考虑词频因素外还充分考虑了XML文档的结构特点对于扩展查询词选取的影响,包括文档中元素的语义权重、元素所在层次和词项与初始查询词间的距离因素对于扩展查询词选取的影响.实验证明本方法是可行的,且能较好地提高检索结果的准确率.  相似文献

LCC from UDC: Managing the conversion     

Lye Tim Wan   《Library Collections, Acquisitions, and Technical Services》2009,33(2-3):73-79

The Singapore Polytechnic (SP) Library embarked on the project to convert books and periodicals from the Universal Decimal Classification system to the Library of Congress Classification (LCC) system after benchmarking projects showed that work performance could be improved upon the conversion. Planning began in 2005 with strong support from SP management. It was decided to carry out the project in-house. Internship at the National University of Singapore Library was arranged for one staff to learn the use of LCC and how special collections and issues were handled. Student assistants were recruited to assist in various processes. In addition, 10,000 bibliographic records were outsourced to a vendor to assign LCC call numbers in order to speed up the project. The library collection was converted and re-shelved during the Polytechnic vacation periods from February 2007 to March 2008, with the Library remaining open throughout the period.  相似文献
