In this paper we describe a new hypertext resource discovery system called a Focused Crawler . The goal of a focused crawler is to selectively seek out pages that are relevant to a pre-defined set of topics . The topics are specified not using keywords, but using exemplary documents. Rather than collecting and indexing all accessible web documents to be able to answer all possible ad-hoc queries, a focused crawler analyzes its crawl boundary to find the links that are likely to be most relevant for the crawl, and avoids irrelevant regions of the web. This leads to significant savings in hardware and network resources, and helps keep the crawl more up-to-date. To achieve such goal-directed crawling, we design two hypertext mining programs that guide our crawler: a
Extractions: Library Catalogue Introduction How to Use the Internet Subject Gateways Structured Directories ... Meta-Search Engines Information is gathered by user input (i.e. they do not employ a robot) and usually the user specifies the category to which the resource belongs and relevant keywords. These resources tend to be more accurate, because of the human intervention, but are less comprehensive because of the lack of automation. They usually deliver a higher quality of content and fewer results out of context than search engines. EINet Galaxy Entitled "the professional's guide to a world of information", Einet Galaxy, like Yahoo!, offers the user elaborate search facilities across a broad range of topics, covering everything from Geoscience to Philosophy. The presentation is not quite as clear as Yahoo!, but there is a great deal of useful information listed here. GeniusFind Categorizes thousands of topic-specific search engines and databases.

Extractions: Searching Indexes and Databases Searching for information on one particular topic is relatively easy: just look up the term you are interested in. But if you want to find sources that discuss a particular set of different topics, it can be time consuming to look up and make lists of all the sources on each individual topic and then pick out those sources which are on all the lists. Also, not being familiar with the specific vocabulary or standard subject terms used for the topic can present difficulties when you do not know what terms to look up (e.g. does the index use "elderly," "senior citizens," or "aged"?). But there are a few tricks to get around these problems when searching for information on a computer database. Here are some common searching techniques which offer powerful tools for quickly and accurately broadening, narrowing, or refining your search on a computer database. Most online indexes and databases have at least some of these search options, but there are often differences in how to use them, so read the help screens for the database you are using.

Extractions: Searching Strategies Introduction Search Engines vs Directories Using Subject Directories Subject Directories Using Search Engines ... Teaching Searching Introduction Many people use search engines without realizing the appropriateness of subject directories to refine their search that will help them find relevant information on their topic. The difference between these two types of tools is difficult to understand. A directory like Yahoo! which is very popular may be used before another directory that could offer more organized categories and a more refined search engine. There are situations where both types of tools can complement each other in the research process. In fact, there are more sites that offer directories at many search engine sites. More directories are expanding to become the one-stop-shop and portal to everyone. So it is a good idea for you to research and try the different engines and directories that are available to determine which would be the best for a particular search. They vary in what content they contain, features they offer, and how accurate the hits are. info@compstrategies.com

It contains over 21,000 bibliographical records and represents the world's largest bibliographic resource for traumatic stress studies. It is available to users worldwide and may be searched free of charge, with no account or password required. As part of the Dartmouth College Information System, the PILOTS database combines a user-friendly search interface with a powerful range of search commands, offering researchers, clinicians, and students ó as well as librarians and other professional literature searchers ó a shortcut to the traumatic stress literature. Like most bibliographic databases, PILOTS provides a bibliographic citation of each paper it indexes, an abstract of its content, and a list of descriptors indicating its subject matter. In addition, each record includes an "Instruments" field listing the psychological and medical assessment instruments used in the research or clinical work reported in the document. This feature enables PILOTS database users to:

Extractions: The tremendous growth in the price-performance of networking and storage has fueled the explosive growth of the web. The amount of information easily accessible from the desktop has dramatically increased by several orders of magnitude in the last few years, and shows no signs of abating. Users of the web are being confronted with the consequent information overload problem. It can be exceedingly difficult to locate resources that are both high-quality and relevant to their information needs. Traditional automated methods for locating information are easily overwhelmed by low-quality and unrelated content. Thus, the second generation of search engines will have to have effective methods for focusing on the most authoritative among these documents. The rich structure implicit in the hyperlinks among Web documents offers a simple, and effective, means to deal with many of these problems. The CLEVER search engine incorporates several algorithms that make use of hyperlink structure for discovering high-quality information on the Web. Ongoing work in the Clever project focuses on higher-level applications based on the basic Clever engine described in the publications below. There are a number of emerging new directions within the CLEVER project.
