Re: [ba-unrev-talk] Ontologies and volunteers
I did a little ruminating on the problem of auto-generating knowledge structures
from ordinary text a while back. My specific intent was to ascertain whether the
conceptual structures of a work written in say 1650C.E. had lost coherence (or
gained a different coherence perhaps) from updating and translation etc.
My thinking led me to the need to be able to autogenerate reference thesauri
from a corpus of the era concerned in order to statistically detect shifts.
Can computers detect synonymous terms automatically?
My thinking on that was no, mostly because I was unable to turn up anything that
said
I could at the time. Anyone out there ever tried it?
Any information much appreciated. (01)
I just made another sweep on google though, in which I incidentally pulled up
http://www.ifla.org/IV/ifla62/62-qiyz.htm (1996) which contains this
revealing passage on a different but related topic:
"Automatic language processing, i.e. automatic term extraction is taken as core
of the use of natural language in information retrieval. Unlike the sentences in
English, French, German and Russian, there is no separation marks in Chinese
sentences. A Chinese character can be combined with many other Chinese
characters to form words and phrases which are different in meaning. It is
difficult for computer to recognize which is a Chinese character or which is a
word made up of several characters, thus to separate them automatically, and it
is difficult t o draw a distinction exactly between useful word and useless
word. In the retrieval using Chinese natural language directly, therefore, it is
necessary to solve the technique that the words can be separated automatically
from Chinese sentences by computer. This technique is called Chinese word
separation technique. Researches in this field have been made, and many
proposals on term separation hav e been offered in the recent years. Generally
speaking, some of them can meet actual needs, thus have been used in the system.
One of the practical systems is Word Extraction by Component Dictionary. Most of
them, however, are still in the stage of experiments. It is because automatic
Chinese term extraction is difficult, contrary to Euro-American, there are few
keyword indexes created automatica lly by computers and information retrieval
systems on the basis of technique of automatic term extraction in China. It can
be said, however, that it is not too far to solve the problem of automatic
Chinese term extraction. " (02)
Makes one realise how powerful the human brain is. (03)
