SV: [SIGMETRICS] extensions of FullText.exe and Ti.ex for co-word analysis with provisions for stop word lists and word frequency lists

[Loet Leydesdorff]

Dear Jesper:

Usually, one gets either an error message or the output. However, let us
take this offline and not both the list with technical details. I'll send
you files shortly. Thanks for trying.

With best wishes,


Loet

> Many thanks for the programme.
> I've tried out your program, but I run into difficulties. I'm
> unable to create .dat files for use with pajek. I use Olle
> Persson's bibexcel program to extract words from titles.
> Subsequently, I make a frequency analysis in order to choose
> the words for the word.txt file in your program - one word
> pr. Line. Next I arrange all the paper titles in a text file,
> one title pr.
> Line and save it with CR/LF as a text.txt file for use with
> your program. I now run the program. I do get dbase IV output
> files, but I do not get the .dat files for use with pajek - I
> wonder where I go wrong?
>
> Could you provide an example of a word.txt and a text.txt
> file - perhaps I can detect my errors?

> Best wishes - Jesper Schneider

> Dear colleagues,
>
> While using the programs in class, it became clear that one
> needs a provision to generate word frequency lists from the
> texts and to correct for stop words. The latter facility is
> now added to these programs (at
> http://www.leydesdorff.net/software/ti/stopword.exe ) and the
> former is set as a hyperlink to TextSTAT-2 of Dutch
> Linguistics Department of the Technical University in Berlin
> (at
> http://www.niederlandistik.fu-berlin.de/textstat/software-en.html).
>
> The programs themselves can be found at
> http://www.leydesdorff.net/software/ti and
> http://www.leydesdorff.net/software/fulltext , respectively.
> For advanced users it may be useful to remark that one can
> also replace the cosine matrices with Pearson correlation
> matrices by feeding the output file matrix.dbf into SPSS and
> running the appropriate routines. In my opinion, some
> convincing arguments have been made to use the cosine as the
> similarity criterion for the visualizations.
>
> With best wishes,
