[Corpora-List] Text Mining for Trend Analysis

[王經篤]

Dear all,

Sorry to bother you again.

I need some corpus with timestamp such that I can compute the "pattern
history" from these corpus. I was blocked with the copywrite issue.
Therefore, I try to seek for cooperation by providing web service of pattern
history if someone could offer his/her corpus.

There is a web site for pattern history and
its URL is (http://120.108.115.115/TM/Search_PubMed_Simple.php).
The pattern history extracted from  medicine articles
"PubMed"( from 1990 to 2009),
containing 3,225,549 articles containing 677,728,269 words (600M+
MILLION WORDS) .

Please don't hesitate to let me know if you are willing to have frequency
distribution of pattern over time from a large and long time periods for
trend analysis.
