Full-text information retrieval: Further analysis and clarification
نویسندگان
چکیده
In 1985, an article by Blair and Maron described a detailed evaluation of the effectiveness of an operational full text retrieval system used to support the defense of a large corporate lawsuit. The following year Salton published an article which called into question the conclusions of the 1985 study. The following article briefly reviews the initial study, replies to the objections raised by the second article, and clarifies several confusions and misunderstandings about the 1985 study.

Homographs are among the words requiring sense disambiguation. Depending on their roles and positions in texts, homograph contexts could be divided to different types, wit...
متن کاملWhat is the role of NLP in text retrieval?
This paper addresses the value of linguistically-motivated indexing (LMI) for document and text retrieval. After reviewing the basic concepts involved and the assumptions on which LMI is based, namely that complex index descriptions and terms are necessary, I consider past and recent research on LMI, and specifically on automated LMI via NLP. Experiments in the first phase of research, to the l...
