  1. 英国《科学文摘》 INSPEC数据库检索

  2. What is INSPEC INSPEC--International Information Services for Physics and Electrical Engineering Communities IEE(英国电气与电子工程师协会）下属单位。 INSPEC成为印刷版《科学文摘》（创刊于1884）的电子产品符号。

  3. INSPEC覆盖的学科范围包括： 原子物理及分子物理，数学和数学物理，凝聚态物理，光学和激光，声学、电力系统，热力学，磁学，生物物理和生物工程，原子物理，核物理，天文学与大气物理，材料科学，水科学与海洋学，环境科学，超导体，电路、电路元件和电路设计，电讯，微电子学，医学电子学，计算机科学，控制系统及理论，人工智能，软件工程，办公室自动化，机器人，情报学等。

  4. INSPEC Database • 7.5 million records (Oct 2002) • 80 countries of publication • 4,200 journals (120 titles from China) • 2,000 conferences per year • 375,000 records added per year

  5. Document Type • Journal articles • Conference proceedings • Conference papers • Technical reports • Books and book chapters • Dissertations • Patents (to 1976 only)

  6. Document types Journal 72.6% Other 2.1% Conference 16.8% Conference in Journal 8.5%

  7. Country of publication Percent

  8. Country of author Percent

  9. INSPEC Database Subjects Electrical & Electronic Engineering(32%) B Physics (58%) A C Computing & Control (28%) Information Technology(8%) D • Launched in 1969 -over 30 years electronic Data

  10.  1 直接进入INSPEC检索 • 简单检索(BASIC) • 高级检索(ADVANCE) • 专家检索(EXPECT)

  11. 简单检索(BASIC) 简单检索将在用户输入的检索内容和关系符组成的检索条件在 Title、Abstract、 Controlled Indexing、 Uncontrolled Indexing、 Full Journal、Title of Conference 六个字段中查询，同时用户还可选择Treatment Codes以及Date Rang。 1.

  12. ：直接在INSPEC查找文献； ：查找JCT（Journal, Classification & Thesaurus）； ：回到选择直接进入INSPEC或JCT的页面； ：查看本次登陆执行的检索命令，如以下页面，用户LOGOFF后检索历史将清除，点击现在查询将重新查看检索结果；

  13. ：查看在线帮助； ：退出系统

  14. Treatment Codes • Applications • Bibliographic • Economic/commercial • Experimental • General or review • New developments • Practical • Product review • Theoretical/Mathematical

  15. 高级检索（ADVANCE SEARCH）

  16. 高级检索(ADVANCE) • 高级检索提供常用字段的检索，各字段间还可实现与、或、非的组配，通过字段下拉框可选取字段。这些常用字段包括： • Title、Classification Codes、Controlled Indexing、 UncontrolledIndexing、Abstract、Affiliation(Author/Editor)、Conf. Title、Full of Journal Title、Author/Editor • 用户还可选择Treatment Codes以及Date Rang。

  17. From Primary Source Free Language Add Value Index Controlled Language Subject Fields on INSPEC-China Title Abstract Uncontrolled Index Controlled Index Special Indexes Classification Codes Treatment Codes Chemical Index Numerical Data Index

  18. 对于Controlled indexing和Classification codes， 用户还可以通过点击 从JCT提取索引。 选中叙词后点击将其送入检索内容。

  19. Uncontrolled=CDMA 1751篇

  20. Controlled Index=code division multiple access 1952篇

  21. Non-Controlled Index Terms • Key words and phrases selected from: document title abstract full text indexer’s expertise • Average 11-12

  22. Non-Controlled Indexing Is Especially Useful for: • New concepts • Product or company names • Geographical terms • Chemical and numerical data (1986 back) • Non-scientific/non-technical topics • Terms that are also common words

  23. Free Language Search - Problems Variations in • Spelling, • Acronyms, • Terminology, • Punctuation Relevance of retrievals may be low

  24. Classification Codes Definition: One field of an INSPEC record that includes alphanumeric codes from the INSPEC Classification selected by indexers to represent the key concepts of the document

  25. Classification Code A - Physics B - Electrical & Electronics C - Computers & Control D - Information Technology Note: To limit your search to any of the database main sections use ‘subfile’ field

  26. First Level Instrumentation & Special Application Second Level Aerospace facilities and techniques Section Code Letter -Electrical & Electronic Engineers Fourth Level (Optional) Aircraft Control Third Level Ground Support Classification Structure B7650C

  27. Subject Search on INSPEC - China Search Tips - overview: • Uncontrolled Index: very useful in searching: • new concepts, • product or company names • geographical terms • Controlled Index: Improve your results. • Classification Codes: Navigating your search • Treatment code: Narrow down your hints

  28. 专家检索 • 专家检索提供用户输入检索表达式和可以将这些检索表达式组配的方式。输入检索表达式以后，点击 按钮，可以将检索表达式保存在待检索列表，输入多个检索表达式以后可以通过点击检索列表中的表达式和页面的逻辑运算符实现表达式的组配。组配后的表达式依然保存在检索列表中，点击 • 执行查询。用户在同一台机器下次登陆仍然可以调用这些检索表达式，点击 也可以删除表达式。

  29. 专家检索 除可使用：* + - ？ 字段代码：TI; AB; BE; F5; F6 ……. 72个字段的检索。 精确词组匹配: “ ” 位置运算：距离等于 ?(1~9) 距离小于 !(1~9) 如：(TI=CDMA+TI=“ code division multiple access”) *F5=CHINA*BE=English Parallel ?(3) simulation

  30. TI=CDMA*F5=CHINA*BE=English

  31.  2 JCT检索 JCT检索通过对JCT库的Thesaurus Term、Classification Title、Journal Full Title、ISSN四个入口进行查询。以下为JCT检索的页面：
