摘要:

文献检索可以说是学术研究和非学术研究中最重要的环节之一。每年发表的论文数量的增加使得人工搜索效率低下,而且不足。因此,自动化的方法,如搜索引擎已在过去的三十年感兴趣。不幸的是,这些传统的引擎使用基于关键字的方法来解决搜索问题,但这些方法容易产生歧义和同义词。另一方面,仅基于引文信息的书目检索技术不容易出现这些问题,因为它们不考虑文本相似性。对于许多特定的研究领域和主题,人类的知识量是巨大的,获得所需的信息就像大海捞针一样困难。此外,有时,我们正在寻找的是一组文件,其中每个文件都与其他文件不同,但同时,作为一个整体,我们希望它们涵盖与我们搜索相关的文献的所有重要部分。本文针对引文检索中的结果多样化问题进行了研究。它调查了一套技术,旨在找到一套具有令人满意的质量和多样性的文件。我们通过方向感知功能增强了这些算法,以允许用户访问旧的、被广泛引用的、知名的研究论文或最近的、不太知名的论文。我们还提出了一套新的技术,更好地多样化的结果。所有考虑的技术进行了比较,通过执行一个严格的实验。结果表明,所提出的一些技术是非常成功的,在实践中进行检索的书目数据库。

英文摘要:

Literature search is arguably one of the most important phases of the academic and non-academic research. The increase in the number of published papers each year makes manual search inefficient and furthermore insufficient. Hence, automatized methods such as search engines have been of interest in the last thirty years. Unfortunately, these traditional engines use keyword-based approaches to solve the search problem, but these approaches are prone to ambiguity and synonymy. On the other hand, bibliographic search techniques based only on the citation information are not prone to these problems since they do not consider textual similarity. For many particular research areas and topics, the amount of knowledge to humankind is immense, and obtaining the desired information is as hard as looking for a needle in a haystack. Furthermore, sometimes, what we are looking for is a set of documents where each one is different than the others, but at the same time, as a whole we want them to cover all the important parts of the literature relevant to our search. This paper targets the problem of result diversification in citation-based bibliographic search. It surveys a set of techniques which aim to find a set of papers with satisfactory quality and diversity. We enhance these algorithms with a direction-awareness functionality to allow the users to reach either old, well-cited, well-known research papers or recent, less-known ones. We also propose a set of novel techniques for a better diversification of the results. All the techniques considered are compared by performing a rigorous experimentation. The results show that some of the proposed techniques are very successful in practice while performing a search in a bibliographic database.
