Before we begin, let's establish what does the term "invisible web" refer to? Simply, it's a catch-all term for online content that will not appear in search results or web directories. There are no official data available, but most experts agree that the invisible web is several times larger than the visible web. The content on the invisible web can be roughly divided into the deep web and the dark web. The Deep Web The deep web made up of content that typically needs some form of accreditation to access. If you have the correct details, you can access the content through a regular web browser. The Dark Web The dark web is a sub-section of the deep web. 1. 2. 3. 4.

“German and Italian antiquarian booksellers and auctioneers are very fond of using abbreviations in their catalogs, sometimes on a rather lavish scale.
This enables them to convey a large amount of information in a relatively short space, but readers not completely fluent in those languages are likely to be left somewhat bewildered, even discouraged, by strings of vowels and consonants occurring either singly or in unfamiliar combinations in the midst of what would otherwise be a fairly comprehensible text. For them, this little dictionary, the first one of its kind, I think, may come in handy. Each abbreviation is followed by the full resolution of the German and Italian word and by its English translation, in most cases with one or more examples illustrating the context and the combinations in which the abbreviation is most likely to occur.”

Thus, its history is comparable to that of a person. Information retrieval had its schoolboy phase of research in the 1950s and early 1960s; it then struggled for adoption in the 1970s but has, in the 1980s and 1990s, reached acceptance as free-text search systems are used routinely. The tension between statistical and intellectual content analysis seemed to be moving towards purelyg statistical methods; now, on the Web, manual linking is coming back. Introduction Shakespeare described seven ages of man, [Shakespeare 1599]. starting from infancy and leading to senility. There has, however, been a tension throughout the life of information retrieval between simple statistical methods and sophisticated information analysis.
