in the early 90 's,IBMpersonal computers are gaining popularity in China. At this point, Intel80286The processor is a "marker". For example,Ibmpc/at 286The personal computer is the "masterpiece" at that time. So-called "At "the meaning is "Advanced techinology "(Advanced Technology).
the earliestIBMPCPc/atappear in1984years, the main frequency only6MHz, MemoryK-B. Later, atthe frequency of the computer increased to8MHz. With Intel386pc of the processor in1987years2month appeared, its frequency increased to33MHzto40MHz. All these are historical facts and are the stories of high school computer textbooks.
in the early 90 's, computer technology was introduced into China from the other side of the ocean. For the domestic industry, the dawn of computing has come. But what do we have to ask for specific questions? According to the preliminary estimate, "The selected works of Deng Xiaoping" is about distances Chinese characters. We asked: How long does it take to find a particular Chinese character in Deng's book using a personal computer? For the simplification of the discussion, we will take the Tang election as a long "big string" to deal with, regardless of the contents structure in the book. Obviously, the frequency of the computer processor is the key to solve the problem.
about in 1992 at the end of the year, the president of Peking University Wu Shuqing me a "task" and asked me if I could use a computer to help people learn and study the works of classical writers such as horses and columns. We have made it clear that in the dawn of the computer, the full-text retrieval system of the voluminous classics is a bit early?
Now, the time has passed more than 20 years, the answer should be opened. However, in the domestic insiders are not many, but I personally came out to say. That is to say, a seemingly impossible thing, how did we really finally make it? This is related to artificial intelligence neural networks (ANN) Support Vector Technology (Support Vector,1990year) concerned. The dawn of the computer is worth a souvenir. Now people talk about cloud computing and big data,1MBmemory is completely negligible. and listen to tell.
Description 1 : The full text of "publication notes" written by the publishing house for the electronic version of "Deng's election" is as follows:
In order to facilitate the readers to study and study Deng Xiaoping's basic theoretical views and policy strategies, especially the construction of socialist theory with Chinese characteristics, we revised the "Selected works of Deng Xiaoping," the first to second edition of the reprint issue, the "works of Deng Xiaoping," the two volumes together with the third volume made into an electronic version of the volume, Public publishing and distribution.
"Selected works of Deng Xiaoping" Tertiary volume electronic version, is approved by the Press and publication department as a national official publication of e-books. It will be the full text of the "Selected works of Deng Xiaoping" and its retrieval system stored on two floppy disks, readers using ordinary microcomputer can be very convenient to read the full text, quickly retrieve any word, word, phrase, sentence, and the page number, contents, paragraphs, lines and the number of occurrences, and can be extracted.
