第七章 常用外文数据库（上机作业）

1、 请简要介绍国外三大检索工具，如何利用三大检索工具等数据库检索相关主题文献，如何利用三大检索工具等数据库检索论文收录情况。

答：

一、国外三大检索工具的介绍

国外三大检索工具：SCI、ISTP、Ei数据库

(1) SCI（《科学引文索引》）是自然科学领域基础理论学科方面的重要的期刊文摘索引数据库，创建于1961年，由美国科学情报研究所（ISI）编制。利用SCI可以检索数学、物理学、化学、天文学、生物学、医学、农业科学以及计算机科学、材料科学等学科方面重要的学术成果信息；SCI还被国内外学术界作为制定学科发展规划和进行学术排名的重要依据。

(2) ISTP（《科学技术会议录索引》）创刊于1978年，由美国科学情报研究所编制，主要收录国际上著名的科技会议文献。它所收录的数据包括农业、环境科学、生物化学、分子生物学、生物技术、医学、工程、计算机科学、化学、物理学等学科。

(3) Ei（《工程索引》）创刊于1884年，目前由Elsevier Engineering Information Inc.编辑出版。主要收录工程技术领域的论文(主要为科技期刊和会议录论文)，数据覆盖了核技术、生物工程、交通运输、化学和工艺工程、照明和光学技术、农业工程和食品技术、计算机和数据处理、应用物理、电子和通信、控制工程、土木工程、机械工程、材料工程、石油、宇航、汽车工程等学科领域。

二、如何利用三大检索工具等数据库检索相关主题文献

1、利用SCI数据库检索相关主题文献

(1) 通过往TOPIC检索入口输入检索主题词获得相关主题文献

(2) 通过往TOPIC检索入口输入检索主题词，然后对检索结果进一步分析获得相关主题文献

(3) 通过往TOPIC和SOURCE TITLE检索入口同时输入检索主题词获得相关主题文献

例子：往TOPIC中输入"nano*"，同时往SOURCE TITLE 中输入"ARTIFICIAL CELLS BLOOD SUBSTITUTES AND IMMOBILIZATION BIOTECHNOLOGY or BIO-MEDICAL MATERIALS AND ENGINEERING or BIOMATERIALS or CELLULAR POLYMERS or DENTAL MATERIALS or JOURNAL OF BIOACTIVE AND COMPATIBLE POLYMERS or JOURNAL OF BIOMATERIALS SCIENCE-POLYMER EDITION or JOURNAL OF BIOMATERIALS APPLICATIONS or JOURNAL OF BIOMEDICAL MATERIALS RESEARCH or JOURNAL OF MATERIALS SCIENCE-MATERIALS IN MEDICINE or MACROMOLECULAR BIOSCIENCE"， 利用上面的检索式，可以检索出SCI网络版2002年数据库收录"MATERIALS SCIENCE, BIOMATERIALS"类的文章102篇。

2．利用ISTP数据库检索相关主题文献

可以通过TOPIC、SOURCE TITLE、CONFERENCE相结合的方式来检索

3．利用Ei数据库检索相关主题文献

例子：检索医学领域中含有 "pipe" 的文献

如果仅仅用 "pipe" 检索在所有字段中检索，会命中 4 万多条记录；即使同时限制在 TITLE 中检索，结果也有 1 万多条，数据冗余太大。这时，可以考虑从学科的角度进行限制检索：

先检索到从 Ei Thesaurus 中检索医学类目：

Medicine ： 461.6 ， Medical care ： 461.7 ， Medical imaging ： 461.1 ， Medical problems ，

Medical supplies ： 462.1 ， Medical computing ： 723.5 ，Medical diagnosis ,Medical education ，

Medical equipment ， Medical monitoring ： 462.2

利用 "Expert Search" ： (461.1 wn CL OR 461.6 wn CL OR 461.7 wn CL OR 462.1 wn CL OR 723.5 wn CL) AND (pipe wn TI) 命中 500 多条记录，因 723.5 类与计算机应用有关，命中记录中有许多看不出是与医学有关的，可以考虑将该类去掉检索。结果就比较令人满意。

三、如何利用三大检索工具等数据库检索论文收录情况

(1) 利用 SCI 数据库检索单位 / 集体论文收录情况

(tsinghua univ or tsing hua univ or qinghua univ or qing hua univ or 100084) same (peoples r china or beijing or bei jing)

(2) 利用 ISTP 数据库检索单位 / 集体论文收录情况

(tsinghua univ or tsing hua univ or qinghua univ or qing hua univ or 100084) same (peoples r china or beijing or bei jing)

(3) 利用 Ei 数据库检索单位 / 集体论文收录情况

利用作者索引或用复杂检索，但效果均不好。

篇名：An effective and efficient results merging strategy for multilingual information retrieval in federated search environments

作者：Luo Si , Jamie Callan ,Suleyman Cetintas ,Hao Yuan

期刊名：Information Retrieval

摘要：Abstract Multilingual information retrieval is generally understood to mean the retrieval of relevant information in multiple target languages in response to a user query in a single source language. In a multilingual federated search environment, different information sources contain documents in different languages. A general search strategy in multilingual federated search environments is to translate the user query to each language of the information sources and run a monolingual search in each information source. It is then necessary to obtain a single ranked document list by merging the inpidual ranked lists from the information sources that are in different languages. This is known as the results merging problem for multilingual information retrieval. Previous research has shown that the simple approach of normalizing source-specific document scores is not effective. On the other side, a more effective merging method was proposed to download and translate all retrieved documents into the source language and generate the final ranked list by running a monolingual search in the search client. The latter method is more effective but is associated with a large amount of online communication and computation costs. This paper proposes an effective and efficient approach for the results merging task of multilingual ranked lists. Particularly, it downloads only a small number of documents from the inpidual ranked lists of each user query to calculate comparable document scores by utilizing both the query-based translation method and the document-based translation method. Then, query-specific and source-specific transformation models can be trained for inpidual ranked lists by using the information of these downloaded documents. These transformation models are used to estimate comparable document scores for all retrieved documents and thus the documents can be sorted into a final ranked list. This merging approach is efficient as only a subset of the retrieved documents are downloaded and translated online. Furthermore, an extensive set of experiments on the Cross-Language Evaluation Forum (CLEF) (http://www.clef-campaign.org/) data has demonstrated the effectiveness of the query-specific and source-specific results merging algorithm against other alternatives. The new research in this paper proposes different variants of the query-specific and source-specific results merging algorithm with different transformation models. This paper also provides thorough experimental results as well as detailed analysis. All of the work substantially extends the preliminary research in (Si and Callan, in: Peters (ed.) Results of the cross-language evaluation forum-CLEF 2005, 2005).

篇名：Towards personalized recommendation by two-step modified Apriori data mining algorithm

摘要：Abstract

In this paper a new method towards automatic personalized recommendation based on the behavior of a single user in accordance with all other users in web-based information systems is introduced. The proposal applies a modified version of the well-known Apriori data miningalgorithm to the logfiles of a website (primarily, an e-commerce or an e-learning site) to help the users to the selection of the best user-tailored links. The paper mainly analyzes the process of discovering association rules in this kind of big repositories and of transforming them into user-adapted recommendations by the two-step modified Apriori technique, which may be described as follows. A first pass of the modified Apriori algorithm verifies the existence of association rules in order to obtain a new repository of transactions that reflect the observed rules. A second pass of the proposed Apriori mechanism aims in discovering the rules that are really inter-associated. This way the behavior of a user is not determined by “what he does” but by “how he does”. Furthermore, an efficient implementation has been performed to obtain results in real-time. As soon as a user closes his session in the websystem, all data are recalculated to take the recent interaction into account for the next recommendations. Early results have shown that it is possible to run this model in websites of medium size.
