ALIWEB belongs to the first web search engines and was developed by Martijn Koster in 1993 at NEXOR a UK based company. At this time web wanderer (like “WebCrawler”) started indexing the web automatically and collecting more or less available information of the sites. This crawler influenced the network and processing of websites, so there was discussion about the use of them. ALIWEB tried to offer an alternative solution without traversing the web automatically. The idea is that people explain their sites and services themselves in a file and tell ALIWEB about. While these files are standards today, as part of a website, they weren’t available in the beginning of the web. First ALIWEB used an own format for the index files, but switched than to the IAFA Template. ALIWEB retrieves the files and combined them in a searchable database. Updated once a day the index and database was very up-to-date. The problem was that not enough people reported about their sites, to create a critical mass of information. That’s why ALIWEB started a corporation CUI W3 Catalog, which uses ALIWEB as a source and integrated them on the CUI W3 site. Too them Nierstrasz, maintainer of the CUI W3 Catalog, suggested people to register with ALIWEB and after presenting ALIWEB on two conferences in 1994 its popularity grows. Since around 1999 ALIWEB was maintained by EMNET (East Midlands Network Limited). Because ALIWEB was only available from a single site with low connectivity, they offered mirror sites at the University of Applied Sciences Wolfenbuettel (Germany), the Universitat Politecnica de Catalunya DAC-UPC (Spain), the National University of Singapore and Aliweb.Com run by ATC (Advertising Technologies Corporation from Alberta, Canada). The last mirror site is still available but seems to be not longer maintained, a lot of the links are closed and the search results comes from an old index I think [kd2015, see the sources given at the end of this side].
»ALIWEB (Archie Like Indexing for the WEB) is considered the first Web search engine, as its predecessors were either built with different purposes (the Wanderer, Gopher) or were literally just indexers (Archie, Veronica and Jughead). First announced in November 1993 by developer Martijn Koster while working at Nexor, and presented in May 1994 at the First International Conference on the World Wide Web at CERN in Geneva, ALIWEB preceded WebCrawler by several months. ALIWEB allowed users to submit the locations of index files on their sites which enabled the search engine to include webpages and add user-written page descriptions and keywords. This empowered webmasters to define the terms that would lead users to their pages, and also avoided setting bots (e.g. the Wanderer, JumpStation) which used up bandwidth. As relatively few people submitted their sites, ALIWEB was not very widely used.« Source
Today Advertising Technologies Corporation use the code, data and name from ALIWEB.
Notes by Martijn Koster: »I have nothing to do with It appears some marketing company has taken the old aliweb code and data, and are using it as a a site for advertising purposes. Their search results are worthless. Their claim to have trademarked "aliweb" I have been unable to confirm in patent searches. My recommendation is that you avoid them.« Source
Wall, Aaron: »In October of 1993 Martijn Koster created Archie-Like Indexing of the Web, or ALIWEB in response to the Wanderer. ALIWEB crawled meta information and allowed users to submit their pages they wanted indexed with their own page description. This meant it needed no bot to collect data and was not using excessive bandwidth. The downside of ALIWEB is that many people did not know how to submit their site.« Source


The »architecture of ALIWEB is very similar to that of Archie, hence the name Archie-Like Indexing in the WEB.« Source

Features & Functionality

»Go ahead and specify as many keywords as you can think of. It won't slow the search down that much, and increases the chance of finding what you want. // If you specify max=200 or some other value n as a keyword, the best n matches will be returned. The default is 50. // If you specify mink=3 or some other value n as a keyword, only items matching at least n keywords will be displayed. The default is 1. // Matches are constrained to word boundaries at the beginning, but not at the end, so cogniti will match cognitive and cognition and meta-cognitivization but not subcognition. Thus, it's usually a good idea to specify just enough of the keyword to be unique. // Matches are done in a case-insensitive fashion. // Only alphanumeric characters, underscore, and hyphen are ``recommended'' characters within keywords. Most other characters should be escaped with a backslash; for instance, to search for information on C++, you would specify C\+\+ as a keyword. People who know perl regexp syntax may use fancier stuff; details here. // Remember WWW is world-wide. Some places say visualization while others spell it visualisation (and some places don't say it in English at all.) That's another reason to just specify, say, visuali as the search keyword. // Boolean and and or are not supported; a heuristic for matching maximal keywords (which I think is preferable to simple booleans) is used. If you really want boolean-style searches, they can sometimes be simulated; for instance, a search for foo and (bar or baz) can be done by specifying keywords foo foo bar baz mink=3. // Boolean not is available, however. If a keyword begins with ! it is interpreted as a negative keyword; for example, if you want to know about data networks but not neural networks, you might specify network !neur as keywords.« Source
