A possible way for Summarization (?)
This is with reference to my earlier mail. Please
let me clarify the way in which I am trying to achieve
the summarization of a passage.
Considerations:
1. There are some words ( many, in fact) which have the
unique characteristic that they are related to many
words. This "super-word" is in relation to other words
found in the directory. Example," sensBe is a general word
and can refer to so many other words. So also is the
word "able" and all its forms, eg "ability", which can
refer to actions by and large.
2> Formulation of a database of such "super-words"
3> the database also contains all the forms of such
"super-words" eg as a verb/noun/adjective/etc
and all the words that are"members of its set" with
varying degrees of membership.
4> It can be seen very easily that the words that are
members of one "super-word" set are also members of maybe
two or three other such "super-words" set, but with varying
degrees of membership. Here, I am conidering the
possibilistic approach.So the total sum of the membership
functions for a normal word to all the sets of
"super-words" is not necessarily equal to one.
5> When the passage is being analysed, i.e. a program
which works like a lexical analyser/ parser,
each word is given weightage according to its
repsective membership funciton to a particular set.
Words such as a/the/as/for can be used to enhance
the effect of the weightage ( this I still have
to work out, how).
6> On the total evaluation of the passage, a set
of words is arrived at. The words in this set
are in turn members of the "super-word" set.
>From this information and the a-priori inforion
about the memberships of each word in the "super-word"
set, a set of minimal most important words is found.
(Intersection using min-max relation). This set of
words now refer to the theme of the passage, and they
themselves amy not actually be present in the passage.
This is because these are the "super-words" and
not te normal words.
7> Formulation of a sentence from this set of words
This is a particularly tough job,and I havent as yet
managed to crack it. Maybe a thorough understanding
of the grammer involved in English sentence formulation
will be needed, before any technique can be proposed.
For the formulation of a sentence froma set of words,
not only is the order of the words is important, but
also the connecting verbs, their meanings and a lot more

Please analyse my technique and advise me on the
shortcomings, and disadvantages.

With warm regards,
Akash
