AskScott - Searching On A Specific Name When searching for a specific name, take advantage of phrase seaching by putting your topic in quotes with appropriate capitalization. http://www.askscott.com/specific.html
Extractions: This technique of phrase searching works only with search tools that index every word on the page and that allow this type of searching. As long as you can put in search terms that have one meaning, you can easily find all the pages about that name. However, if your search term has other meanings, the searching can be more difficult. Google is used by some people for many different searches. As it indexes every word, it can be a very frustrating tool to use if your search isn't specific. Searching on a specific name When searching for a specific name, take advantage of "phrase seaching " by putting your topic in quotes with appropriate capitalization. (for example: "Six Flags over Texas") or Find this: If this returns no results, then remove the quotes or alter the phrase. If this returns too many results, then use the - (minus sign) before an aspect of the returned pages that you aren't interested in. (for example, "Texas Rangers" -baseball will find pages with the phrase Texas Rangers but without the term baseball) If this doesn't help, you can either go

The sooner you can develop a broad subject into a focused topic, the sooner you can shape your research into a finished paper. On the other hand, if your subject is too focused or detailed , you may have a hard time finding enough sources to write an acceptable paper. In this case, to need to broaden your topic If you need assistance refining your topic, please consult any reference librarian A topic that covers too much material is a common problem for students. Depending on your interests, a general topic can be focused in many ways. For example, if you want to do a paper on government funding of the arts, consider the following questions: What do you already know about this subject? Is there a specific time period you want to cover?

Extractions: Duke Libraries Guide to Library Research Site Map Part 1: Choosing a Topic CHOOSING A TOPIC What are you going to research? Sometimes choosing a topic is the biggest hurdle in doing research. Your instructor may assign a general or specific topic, or the choice may be up to you. Knowing where to look for ideas will help you find an interesting subject. Where can you get ideas? Your interests , the things you have been reading, and conversations you have had in class or with others are often good sources of ideas. Sources of background information like general encyclopedias, subject-specific encyclopedias or dictionaries, or textbooks can be sources of ideas. Current periodicals may give you an idea of hot research topics. Look through some recent issues of journals or magazines in the Current Periodicals collection in Perkins Library. Browsing the shelves in the library is also a good way to get an idea of topics which have intrigued authors. Consult this general browsing guide to find out where books on a general subject are shelved. Since books at Duke are shelved together by topic, once you have identified the

When your are beginning your research, you may want to choose a general database or printed reference works to find background information on your topic.
Focused Crawling: The Quest For Topic-specific Portals information, tailored to the needs of specific communities interesting the page is,given the topic of the How can surfing, searching and bookmarking actions of http://www.cs.berkeley.edu/~soumen/focus/
Extractions: T WO FORCES are shaping the future of the web away from generic portals to specific portholes - search and directory sites that are targeted to web-mature audiences interested in deep, high-quality information on specific subjects, sites that trawl for the needles and leave the haystacks alone. One force is the exploding volume of web publication. The major web crawlers harness dozens of powerful processors and hundreds of gigabytes of storage using superbly crafted software, and yet cover 30-40% of the web. Scaling up the operation may be feasible, but useless. Already, the sheer diversity of content at a generic search site snares all but the most crafty queries in irrelevant results. The second force is the growing mass of savvy users who use the web for serious research. Although keyword search and directory browsing are still essential services, these are no longer sufficient for their needs. They need tools for ad-hoc search, profile-based background search, find-similar search, classification, and clustering of dynamic views of a narrow section of the web. There is growing consensus that small is beautiful: as the web grows, a large number of portals, each of which specializes deeply in a topical area, will be preferable to universal, one-size-fits-all search portals. The following recent articles bear testimony to this imminent trend.

Second Generation Searching On The Web When you are looking for a specific site or targeted topic and want natural languagesearch, truncation, case sensitivity and field searching; Ixquick sends http://library.albany.edu/internet/second.html
Extractions: Back to Internet Tutorials Second Generation Searching on the Web Updated: 14 March 2003 This tutorial covers some of the newer search engine services on the Web. It includes a group of search services that make use of technology that organizes search results by peer ranking, or clusters results by concept, site or domain. This is in contrast to the more long-standing method of term relevancy ranking. This newer type of ranking often looks at "off the page" information to determine the retrieval and order of your search results. Search engines that employ this alternative may be thought of as second generation search services. For example: Here are a few of the trends to watch with second-generation services: The human element: concept processing. Second generation services such as Ask Jeeves and SurfWax apply different kinds of concept processing to a search statement to determine the probable intent of a search. This is often accomplished by the use of human generated indexes. With these services, the burden of coming up with precise or extensive terminology is shifted from the user to the engine. These services are therefore taking on the role of thesauri. The human element: horizontal presentation of results.
Teaching With Technology Before having students work on a project that involves Internet searching,try identifying topicspecific search tools and sites. http://teacher.scholastic.com/technology/tutor/websearch.htm
Extractions: Looking for strategies to search the Web for the content you want? These Web lessons from Tom Snyder Productions are designed for the beginning Web user. SPECIALIZED SEARCHES It will certainly help some students when working on research to know they can "specialize" their search. This approach, though, is probably most helpful for the teacher who is struggling with the huge amounts of time traditional searches seem to take. Before having students work on a project that involves Internet searching, try identifying topic-specific search tools and sites. Have students use these as starting points. Better yet, create your own list of topic-specific tools and sites. You're going to be doing an interdisciplinary unit with some other teachers at your school. The unifying theme will be the environment. You need to gather some Web resources, and you want to rely on others who have already put together lists of environmental resources on the Web. Find one or two topic-specific lists.

Extractions: Guide to Effective Searching of the Internet Section 1: Searching with Internet Provided Resources Your ability to find the information you seek on the Internet is a function of how precise your queries are and how effectively you use search services. Poor queries return poor results; good queries return great results. Contrary to the hype surrounding "intelligent agents" and "artificial intelligence," the fact remains that search results are only as good as the query you pose and how you search. There is no silver bullet. There are very effective ways to "structure" a query and use special operators to target the results you seek. Absent these techniques, you will spend endless hours looking at useless documents that do not contain the information you want. Or you will give up in frustration after search-click-download-reviewing long lists of documents before you find what you want.

Extractions: Updated: 20 November 2002 Reaction chemists are interested in a variety of information when planning a synthesis. That may include the conditions under which the reaction is to occur, the starting materials and reagents, catalysts, reaction sites, yields, products, by-products, functional group transformations, bonding changes, and mechanisms of the reactions. [A reaction MECHANISM is "a detailed description of a particular reactant to product path, together with information pertaining to intermediates, transition states, stereochemistry, the rate-limiting step, electronic excitation and transfer, and the presence of any loose or intimate electron ion pairs." (Ash, 1985)] A combination of some or all of these concepts may provide a path to the needed information, depending on the secondary source that is used. Once a compound has been synthesized, a variety of analytical and physical property techniques may be used to verify that the correct substance has been made. One way to search for reaction information is by the name of the reaction. That may be a more general name, such as a substitution reaction, or it may be an eponym from the name of the chemists(s) who first developed the synthetic method, such as the Curtius Rearrangement Reaction. Other search systems have developed around codes for various key features in the reaction.

Introduction. Reaction chemists are interested in a variety of things when planning a synthesis. The conditions under which the reaction occurs, the starting materials and reagents, catalysts, reaction sites, mechanisms of the reactions, yields, products, by-products, functional group transformations, and the bonding changes are among the items that may be of interest in a search for reaction information. A combination of some or all of these concepts may provide a path to the needed information, depending on the secondary source that is used. Once a compound has been synthesized, a variety of analytical and physical property techniques may be used to verify that the substance is actually what was intended to be made. One way to search for reaction information is by the name of the reaction.
