The Invisible Web: Uncovering Information Sources Search Engines Can't See

Description:

Gary Price and Chris Sherman , Foreword by Danny Sullivan, Search Engine Watch

Infiltrating the hidden Internet that typical search engines miss

Enormous expanses of the Internet are unreachable with standard web search engines. This book provides the key to finding these hidden resources by identifying how to uncover and use invisible web resources. Mapping the invisible Web, when and how to use it, assessing the validity of the information, and the future of Web searching are topics covered in detail. Only 16 percent of Net-based information can be located using a general search engine. The other 84 percent is what is referred to as the invisible Web—made up of information stored in databases. Unlike pages on the visible Web, information in databases is generally inaccessible to the software spiders and crawlers that compile search engine indexes. As Web technology improves, more and more information is being stored in databases that feed into dynamically generated Web pages. The tips provided in this resource will ensure that those databases are exposed and Net-based research will be conducted in the most thorough and effective manner.

深入探索一般搜索引擎無法搜尋到的隱藏網絡。
這本書提供了找到這些隱藏資源的關鍵，包括如何發現和使用不可見的網絡資源、如何評估資訊的有效性以及網絡搜索的未來等詳細內容。
僅有16%的網絡資訊可以通過一般搜索引擎找到，其餘的84%被稱為隱藏網絡，包含存儲在數據庫中的資訊。與可見網絡上的頁面不同，數據庫中的資訊通常無法被軟體蜘蛛和爬蟲索引。隨著網絡技術的進步，越來越多的資訊被存儲在數據庫中，並生成動態網頁。本書提供的技巧將確保這些數據庫被揭示，並以最全面和有效的方式進行網絡研究。
