An iterative technique for phrase query formation and an information retrieval system employing same

Jan O Pedersen, +5 more
TL;DR: In this paper, an information retrieval system and method are provided in which an operator inputs one or more query words which are used to determine a search key for searching through a corpus of documents, and which returns any matches between the search key and the corpora of documents as a phrase containing the word data matching the query word(s), a non-stop (content) word next adjacent to the matching word data, and all intervening stop-words between the matching data and the next adjacent nonstop word.
