Retrieval : Theory
نویسنده
چکیده
We present the state of the art of the main component of text retrieval systems: the searching engine. We outline the main lines of research and issues involved. We survey recently published results for text searching and we explore the gap between theoretical vs. practical algorithms. The main observation is that simpler ideas are better in practice. 1597 Shaks. Lover's Compl. 2 From oo a hill whose concaue wombe reworded A plaintfull story from a sistring vale.
