1、WEB OF SCIENCE中检索式的编写(其他数据库中编写的思路是一样的,只要根据其数据库的各种算符的规定即可)1. 逻辑算符:and or not2. 通用截词符:*等.3. 优先算符:()4. 位置算符:;near 等WEB OF SCIENCE逻辑运算符优先顺序如果在检索式中使用不同的运算符,则会根据下面的优先顺序处理检索式:NEAR/xSAMENOTANDOR每个数据库中的位置算符都不尽相同,要具体情况具体对待 如果2个检索词就这样摆在这,中间不加任何检索算符,系统一般默一我,你认是and的关系,但是索词之间的关系定义清楚! !我们学习了各种算符,血不允许囚就 饷人f全人炎虫、日静、
2、专样尚左、专要用各种算符把 把2个或多个检索词就这样放在这,K联合国International Court of JusticeInternational Court of Justice美国:USA / U.S. / United States / America / American / United States of America / United States of American正确的检索式:(USA or U.S. or United States or America or American or United States of America or United Sta

4、是我们想要 的“美国”思路:1. 首先是想要研究某领域中的某一课题;2. 想要查资料,中文,英文3. 确定数据库,一定要根据课题内容来确定数据库中文数据库:CNKI;维普;万方等英文数据库:web of science; ProQuest 平台上的 Dissertations and Theses A&I: The Sciences and Engineering Collection (简称 PQDT); ProQuest Research Library(简称 ARL); LexisNexis; EBSCO 的 ASP、BSP; Springer LINK; Elsevier SD等等4.
5、 在不同的数据库中,根据各数据库的算符规定,编写出能检索出我们自己想要文献的检索式,就是符合要求的检索式5. 在数据库中运行检索式,检索出符合要求的参考文献。6. 将检索出的文献保存到EndNote; NoteFirst等文献管理软件中;7. 在对检索出的文献进行阅读、研究后,写出自己的研究成果,即 自己的文章,投稿,发表!一.研究的课题:综合调度的优化模型以及模型的求解算法。在优化模型的建立方面, 充分考虑重大自然灾害应急响应中存在的应急资源需求量、疏散人员 数量和位置、应急资源和疏散人员的运送时间等信息具有不确定性的 情况,综合运用网络流规划、不确定规划等方法,建立重大自然灾害 中应急资源
6、与疏散人员综合调度的优化模型。针对所建立的模型的复 杂特性,设计能够有效求解模型的智能优化算法,通过仿真实验验证 模型和算法的有效性和可行性。二想要查找下列研究方面的文献:1. 以重大自然灾害应急响应为背景,同时考虑应急资源和疏散人员的优化调度问题,通过优化模型的建立及求解获得最优调度方案;2. 在模型构建中考虑重大自然灾害环境下应急资源的需求量、疏散人员的数量和位置、应急资源和疏散人员的运送时间等信息中具有模糊 信息、随机信息等各类不确定信息的情况,综合运用网络流规划和不 确定规划建立优化调度模型,并开发求解模型的智能优化算法。三.我们在web of science中查找文献想要查找:优化调
7、度问题,通过优化模型的建立及求解获得最优调度方案;1.首先要了解web of science中的算符规定:布尔逻辑运算符AND使用AND可查找包含被该运算符分开的所有检索词的记录。OR使用OR可查找包含被该运算符分开的任何检索词的记录。NOT使用NOT可将包含特定检索词的记录从检索结果中排除。位置限定运算符NEAR/x X乂0使用NEAR/x可查找由该运算符连接的检索词之间相隔指定数 量的单词的记录。该规则也适用于单词处于不同字段的情况。 用数字取代x可指定将检索词分开的最大单词数。如果只使用NEAR而不使用/x,则系统将查找其中的检索词由NEAR连接且彼此相隔不到15个单词的记录。例如,以下
8、检 索式效果相同:salmon NEAR virussalmon NEAR/15 virus请注意.您不能在“主题”和“标题”检索式中将AND运算符作为NEAR 运算符的一部分使用。例如,以下检索式是有效的。TS=(Brown NEAR spider bite)但是,TS=(Brown NEAR spider bite)就是无效的,因为 AND是检 索词spider与bite之间的隐含运算符。另一方面,OG=(Brown NEAR Rhode Island)是有效的,因为此字 段标识在检索词Rhode和Island之间调用了一个隐含的 NEAR运算符。单词NEAR出现在标题中如果来源文献(如期
9、刊、书籍或会议录文献)的标题中包含单词 NEAR,检索时请使用引号()将其引起。例如,在“标题” 字段输入以下文本将返回一条记录。Atomistic simulations of a solid/liquid interface: a combined force field and first principles approach to the structure and dynamics of acetonitrile near an anatase如果未使用引号,系统会返回如下错误消息:“检索错误:NEAR 运算符使用无效”SAME在地址检索中,使用SAME可查找该运算符所分隔的检索词
10、出 现在同一个地址中的记录。您需要使用括号来分组地址检索词。例如:AD=(Portland SAME Oregon)查找在记录“地址”字段中存在地址检索词Portland、Oregon或 OR的记录。请注意,当在其他字段(如“主题”和“标题”)中使用时,如果检索词出现在同一记录中,SAME与AND的作用就完全相同。例如:TS=(cat SAME mouse)与 TS=(cat AND mouse)将得到相同的结果。逻辑运算符优先顺序 如果在检索式中使用不同的运算符,则会根据下面的优先顺序处 理检索式:NEAR/xSAMENOTANDOR copper OR lead AND algae可查找同
11、时存在lead和algae的所有记录以及存在单词copper的所有记录。(copper OR lead) AND algae可查找同时存在单词 algae与 copper和同时存在algae与lead的所有记录。使用括号使用括号可以忽略运算符优先级。括号内的表达式优先执行。(cadmium AND gill*) NOT Pisces 可查找包含 cadmium 和 gill (或 gills)的记录,但排除包含单词Pisces的记录。(salmon OR pike) NEAR/10 virus 可查找 salmon 或 pike 与 virus 相隔不到10个单词的记录。通配符所有可以使用单词
12、和短语的检索字段均可以使用通配符。它们 可在检索式中表示未知字符。星号(*)表示任何字符组,包括空字符。问号(?)表示任意一个字符。美元符号($)表示零或一个字符。有关通配符的一般规则通配符可位于检索词的中间。例如,odo$r可查找到odor和 odour。您不能在以下字符后面使用通配符:特殊字符(/ #)和标点符 号(.,:;!)。您不能在出版年检索中使用通配符。例如,可以使用2007,但 不能使用200*。如果通配符出现在单词或名称中,您就不能对其进行检索。可以在引号内使用美元符号($)。例如,检索式RomanNumeral$ 查找包含检索词 Roman Numeral 或 Roman N
13、umerals的记录。在检索式中最多可使用30个布尔运算符。在“检索”页面的 检索式中,不能在单个字段中或多个字段之间使用超过30个通 配符。注意:建议检索包含连字号(-)或撇号的姓名时不使用美元符 号($)和问号(?)等通配符,否则产品返回的记录可能减少。有用窍门美元符号($)对于查找同一单词的英国拼写和美国拼写非常有用。例如,flavo$r 可查找 flavor 和 flavour。问号(?)对于检索最后一个字符不确定的作者姓氏非常有用。例如,Barthold?可查找Bartholdi和Bartholdy,但不会查找Barthodo短语检索若要精确查找短语,请用引号括住短语。例如,检索式e
14、nergyconservation将检索包含精确短语energy conservation 的记 录。这仅适用于“主题”和“标题”检索。如果输入不带引号的短语,则检索引擎将检索包含您所输入的所 有单词的记录。这些单词可能连在一起出现,也可能不连在一 起出现。例如,energy conservation将查找包含精确短语energy conservation的记录, 还会查找到包含短语 conservation of energy的记录。如果输入以连字号、句号或逗号分隔的两个单词,则词语将视为 精确短语。 例如,检索词waste-water将查找包含精确短语 waste-water或短语 was
15、te water的记录, 而不会查找包含 water waste、waste in drinking water 或 water extracted from waste的记录。括号括号用于将合成布尔运算符进行分组。例如:(Antibiotic OR Antiviral) AND (Alga* OR Seaweed)(Pagets OR Pagets) AND (cell* AND tumor*)撇号撇号被视为空格,是不可检索字符。请确保检索不带撇号的不 同拼写形式。例如,Pagets OR Pagets可查找包含Pagets和 Pagets的记录。连字号输入带连字号或不带连字号的检索词可以检
16、索用连字号连接的单词和短语。 例如,speech-impairment可查找包含 speech-impairment 和 speech impairment 的记录。2. 分析课题,找出主题词及同义词以重大自然灾害应急响应为背景,同时考虑应急资源和疏散人员的优化调度问题,通过优化模型的建立及求解获得最优调度方案;1. 灾害 / 灾难disaster / disasters / hazard / hazards2. 海啸tsunami3. 飓风hurricane4. 地震earthquake / earthquakes / seismic / seismological5. 洪水flood /

The results show that the proposed method can find the approximate optimal solution effectively.入藏号:WOS:000282107600357语种:English文
