This is a prototype gopher server experimenting with Chinese
full text searches using a modified waisindex. The data are
not complete and you should not expect to up-to-date and
meaningful data here until we annouce this server on the
network, most probably through the newsgroup tw.announce
ncu.annnounce and the mailing list [email-masked] and
[email-masked].

o If you see strange characters to the left of the menu they
  are Chinese characters using the BIG5 encoding scheme.

  (if you are in Taiwan, you shouldn't have much trouble here,
  any PC with ETen, and modified PC Gopher availiable from
  imftp.mgt.ncu.edu.tw:/pub/chinese/cgopher_pc.zip should do,
  Macs with ChineseTalk or MacChina and TurboGopher works
  too, or you can get cxterm for X Window System and a
  slightly modified Unix gopher client from
  imftp.mgt.ncu.edu.tw:/pub/chinese/cgopher_sun4.Z)

o The data items are not updated regularly, browse around
  and try out the search items since it is the feature of this
  system.

  (try "Ask Me" and type "library", two files should appear
  both files contain the words "library" the second file only
  contains the Chinese words for library "twu2 su1 guan3" or "�����]"
  searching for words in either Chinese or English is the
  same ( hmm, only activated on the Ask Me(demo) item currently)
  - we call this phrase conversion feature 'aliasing')

o The system should be able to recognize phrases listed under
  the Phrase item, in that case, you do not need to separate
  the words with an extra space.

  (since aliasing is not activated for the other items,
  you should search English words in English and Chinese
  words in Chinese, which means you're out of luck if you
  don't have a Chinese system. Now try the "Help Me"/"All Phrases"
  item, you'll see the Chinese phrase "���@" (un-uniform)  in the file "aa".
  Search for the phrase "���@" with the Help Me"/"Search Phrases"
  item. You should see 6 files, looking at the end of file "ch"
  you'll see "�j�p���@" (un-uniform size). Tell us if you find a bug! )

o For the other search items demostrating Chinese full text searches,
  you should type "the Chinese words to search for" SEPARATED by spaces

  (yup, that's the way it is now, we'll improve.
  What the system is doing now is matching indivdual keywords with
  the boolean AND operator. Let us experiment under the
  "Dept. of Mathematics"/ "Ask Me" item.  If you type a query like
  "���T��ˇ" (300 poems of the Tang Period)
  it will fail since there is no such phrase, but try
  "��" (Tang Poems) and your get the right item. Perform another
  search but this time try "�� ��". Hopefully you can now understand the
  important of phrases in Chinese searches! )

o Now you can browse and play around these items:

      7.  Dept of Info Management [���T��z���t]/
      8.  Dept of Mathematics     [���t]/
      9.  Campus Computer Center  [�q������]/

  the other folders (directories) are placeholders for the
  future. You might find some treasures hidden, but don't
  try them if you are not in a playful mood.

o You should be sending all your fruhstrating experiences to the
  mailing list [email-masked]! We look forward to your
  input, so far we haven't received ANY!

o We are working on the patches to be released, but it seems
  that users do not know how to search and failed to find
  interesting data on this server, don't lose faith, we
  are trying our best! Happy searching!

o We thank the Ministry of Education Computer Center for supporting
  the CWAIS (Chinese Wide Area Information System) Project,
  Dr. C. K. Farn and Dr. J. S. Chen for directing this project.
