Finding Out About（ISBN=9780521734462） 英文原版 umd mobi chm 夸克云 免费 azw3 下载 pdf

　　Finding Out About explains how to build useful tools for

searching collections of text and other media. In the process it

takes a close look at the properties of textual documents that do

not become clear until very large collections of them are brought

together and shows that the constructions of effective search

engines requires knowledge of the statistical and mathematical

properties of linguistic phenomena, as well as an appreciation for

the cognitive foundation we bring to the task as language users.

The unique approach of this book is its even handling of the

phenomena of both numbers and words, giving it a wide appeal. The

textbook works for undergraduate and graduate classes on

information retrieval, library science, and computational

linguistics. More exercises are available to instructors. A

supporting Web site includes recent additions to the book, as well

as links to sites of new topics and methods.
