1. Elsevier 爱思维尔

如今，没有信息检索（IR）系统支持，学术搜索就如同大海捞针。就像Manning等人（2009）的解释一样，IR是一个从大型集合中发现的非结构化材料的过程，以满足学术领域的信息需求。 一般来说，用户喜欢谷歌而不是其他专业网站和数据库。然而，IR的作用使它更容易满足信息需求，因此我们不应忽视学术搜索领域中的专业数据库。我们知道，爱思唯尔是世界领先的网站，也是一个大型数据库，它不仅出版医学文章、期刊、书籍和科学文献，而且为科学和卫生领域的客户提供数字信息解决方案服务。在本报告中，爱思唯尔将被选为IR分析的一个例子。
Nowadays, without information retrieval(IR) system support, academic searching is like to find a rice grain in haystack. Just like the interpretation of Manning et al (2009), IR is as a process of unstructured materials found from a large collection in order to satisfy the information needsin academic field. In general, users prefer Google rather than other professional website and database. However, the role of IR makes it more easily to meet the information needs so that we should not ignore the professional database in the academic search field. As we know, Elsevier is a world-leading website and is also a big database, which not only publishes the articles, journals, books and scientific literatures of medical, but also provides the digital information solution service for customers in Science and health field. In the present report, Elsevier will be chosen as an example of IR analysis.

2. Method方法论

In this section, two different types of searching tasks will be occupied. In the first task of known item search, which means we would like to search a particular item we know, but have no idea the location. In practice, we adopt a specific journal named “Materials Science and Engineering: A” as an example to evaluate Elsevier IR system. We tried to enter the correct as well as the misspelled items into the search process to test whether the correct spelling reminders and recommendations are suggested in the result. The search can be performed by using the items like “matarials” or “materials scence” as the key word for testing. In the second task of search for introductory materials, we would to find the relevant document of “definition of nanomaterials” through “find a article” section to search, in order to evaluate Elsevier IR system.In addition, another purpose of this research is to get professional introductionquickly using the refining tools, such as “titles”, “author name” and “journal or book titles” to quickly searched the relevant materials in the database.
