Intelligent search engines

Abstract

The traditional way of information retrieval is to type the search string into the search box, and the system finds the matching hits from target text. It has been possible to truncate the words using the asterisk in appropriate places. It has also been possible to use Boolean operators such as AND and OR for combined search. For isolating languages such as English, such a system works quite well. The situation is very diffrent with inflecting languages such as Finnish, which inflects to the right from the stem, or Swahili, which inflects to both directions from the stem. Without proper morphological analysis it is very hard to formulate the search string so that the result is satisfactory. In this report I will describe the latest developments in accurate information retrieval. It is an extension to the Technical Report No. 36 (Hurskainen 2019a) and 44 (Hurskainen 2019b).
