Who announced the early web search engine ALIWEB in 1993?

Martijn Koster announced the early web search engine ALIWEB in 1993.

Koster announced ALIWEB in November 1993 while working at the British company Nexor. He later presented the project at the First International Conference on the World Wide Web at CERN in May 1994. ALIWEB is widely described as the first Web search engine, although early search history also includes related pioneering systems such as W3Catalog and the World Wide Web Wanderer.

ALIWEB’s method differed sharply from modern crawler-based search. It did not send a robot automatically across the Web. Instead, webmasters submitted the locations of specially formatted index files, along with descriptions and keywords for their pages. This reduced the bandwidth burden caused by automated crawlers and gave site owners control over their listings.

The answer choices are easy to confuse because Brian Pinkerton created WebCrawler, Jonathon Fletcher created JumpStation, and Matthew Gray developed the World Wide Web Wanderer and its index, Wandex. Koster is also associated with the Robots Exclusion Standard, the convention later represented by robots.txt.
