Chatterbox conversational clusters

The last hour's chatterbox is graphed to clump around who was talking to whom. Sort of. This doesn't take into account message content so if you say someone's name, that doesn't hint that you are talking to them. You get points by speaking recently and within proximity to when someone else spoke.

Incidentally, I'm bringing these links up in PMD because while the code is visible I'm not presenting complete packages so people can run this stuff on their own. In that sense its more just an introduction to another view to perlmonks.

Appended: I added the PL/R code so people could see that too. The full source code for everything is at http://grenekatz.org/downloads/chatterbox//sql/perlmonks.sql.

CREATE FUNCTION r_median(double precision[]) RETURNS double precision AS ' median(arg1) ' LANGUAGE plr; CREATE AGGREGATE median ( BASETYPE = double precision, SFUNC = plr_array_accum, STYPE = double precision[], FINALFUNC = r_median ); CREATE FUNCTION invisible_speakers() RETURNS SETOF text AS ' SELECT username FROM (SELECT userid FROM chatter AS c, ( SELECT MAX( inserted ) AS s FROM other_users ) as s, ( SELECT MAX( inserted ) AS f FROM current_other_users ) AS + f WHERE c.inserted BETWEEN s.s AND f.f EXCEPT SELECT userid FROM current_other_users) AS i JOIN users USING (userid); ' LANGUAGE sql STABLE;

    This is really cool, thanks! There's been a lot of work lately on visual maps of social networks and information source. For example here's a visual map of google news items

    Way too cool! I'm going to borrow some expressions from your queries.

    I do almost the same for our local irc channel, but connections are based only on number of directly addressed (=~ /^$nick/) messages. And GraphViz helps to avoid writing .DOT files.

    BTW, I've ported PieSpy from Java to Perl (irssi script incarnation), you can get it here together with some sample output (ie. latest FreeNode #perl social network). It does similiar thing like the chatterbox monitor, but with IRC channels. It includes a neat cute-looking layouter and renderer (nothing ugly like GraphViz), I'm in the process of CPAN'izing that part right now.
      Great! So you'll let me know when you've uploaded it? What are you going to call the graphing portion?

    FYI: Graph::Layouter was recently released, which means you don't have to exec neato, you can do it all in pure perl.

    This is really nifty. Now all we need is a topic cluster graph. =)
