Open Source: tOKo, Sigmund, BlogTrace

I cannot remember having mentioned it before, but "one of the things" I'm currently working on is an Open Source version of the tools I have been blogging about. My experience with Open Source as a developer is a bit half-baked: I'm listed as the second author of the immensely popular SWI-Prolog environment. Although this is factually correct, I designed and wrote the first version of the GUI environment, Jan Wielemaker is maintaining it and setting a high standard doing that. Obviously, all the tools I develop are written in SWI-Prolog with some C-language code when high performance is required.

My first step towards Open Source was integrating the stable parts of tOKo, Sigmund and parts of BlogTrace into a single project (the whole is called tOKo). I more or less finished doing that last week. Most Open Source projects, contrary to what the name suggests, appear to rely on a few developers and (many) users who contribute by commenting, finding bugs etc. tOKo is currently pre-alpha, meaning that its circulation is restricted to those from whom I can expect feedback. One striking case is a student at Océ who is using the Sigmund part to extract significant terms from Océ's huge document archive. This has resulted in a more or less endless stream of bug reports, mostly related to the size of the data-set and Sigmund not being particularly fluent at Dutch. The conclusion must be that one actually needs users and their data to iron out (some of) the bugs.

What should be the next step? I received a hint during a workshop on "Digital Traces" last Friday. My contribution was a demo of the integrated version of tOKo, particularly the parts that analyse weblog communities. There are some pictures of that demonstration on Flickr I have been told. The hint was something along the lines "I would like to use this software" (apparently even Microsoft Research is interested :-)). Fine, but this is Open Source: so you'll have to contribute yourself as well.

There are globally two application areas for tOKo: ontology development and "viewing" weblogs from a different angle. The first application area is currently well-covered by projects, the second application area suffers a bit from the fact that it is awfully difficult to acquire clean weblog data. The interesting thing is that ideas resulting from weblog analysis contribute towards ontology development (and vice versa).

For the time being the next step is therefore to contact bloggers to participate. If either myself or Lilia contacts you, please consider you will be a certified contributor to an Open Source project (as well as a guinea pig)!

I'm not sure what my picture as a "blog researcher" looks like (I don't use categories). Below is Lilia's picture (based on the posts she assigned "blogging as research" compared to her entire blog; Image courtesy of tOKo which includes Sigmund and parts of BlogTrace, and Lilia for providing the data :-)).

In various parts of the world, the educational background for nurses varies widely.
In some parts of eastern Europe, nurses are high school graduates with twelve to eighteen months of training.
In contrast, Chile requires any registered nurse to have at least a bachelor's degree.
In the United Kingdom, nurses must attend a university in order to qualify as a nurse.
Student obtain either a High National Diploma or a Bachelor's Degree
(which varies from institution to institution; some may award BCs,
whilst others may award a BN). Some university courses attract an Honours Degree
(eg BN (Hons)). The requirements for the degree or the diploma are set down by the Nursing and Midwifery Council (NMC),
which is the regulatory body for nursing and midwifery.
Typically, http://luxmann-sib.ru>student nurses will complete a minimum of three extended (42 weeks) academic years,
of which 50% is theoretical and 50% is practical.
A variety of placements are attended during this time, including care of the elderly,
medical and surgical wards, community and critical care.
Some students may get to experience a short placement in maternity, too.
http://luxmann-sib.ru>Nurses are the most needed workers in the medical field today,
there are over thousand registered nurses in the United States of America (U.S.) alone,
comprising about 13% of the fifteen thousand workers in the health care and social assistance
category tracked by the U.S. Department of Labor

Use a dictionary and grammar guide constantly. Keep a small English dictionary with you at all time. When you see a new word, look it up. Think about the word - use it, in your mind, in a sentence.

Посмотрев эту страницу, я просто не смог удержаться от комментариев.
http://god-ok.ru/Katalog%20HTML/bosh.html>"Сервис от BOSCH"
Сервису от BOSCH на Украине пофиг закон Защиты прав потребителей.

Человек к ним обратился за помощью согласно закона, а они вместо того чтоб
приехать и заменить по просту, ему угрожают судебной расправой, возникает
вопрос где прокуратура, куда смотрит кабмин, где руководство, что они там у
себя в германии думают.

-а это для немцев-
Der Service von BOSCH hat alle u"bertroffen! Allem zu lesen!!!
Dem Service von BOSCH in der Ukraine ohne Bedeutung das Gesetz des Schutzes der
Rechte der Konsumenten. Diese Seite angeschaut, konnte ich einfach von den Kommentaren
nicht festgehalten werden. Der Service von BOSCH in der Ukraine ignoriert das Gesetz des
Schutzes der Rechte der Konsumenten. Der Mensch an ihn hat hinter der Hilfe einverstanden
des Gesetzes, und sie anstelle dessen damit behandelt Anzukommen und die minderwertige
Ku"chenmaschine zu ersetzen, ihm drohen mit der gerichtlichen Abrechnung, es entsteht die
Frage wo die Staatsanwaltschaft, wohin den Ministerkabinett sieht, wo die Fu"hrung, dass sie
dort bei sich in Deutschland denken.

Мне все равно как Вы поступите, будете платить или экономить,
но есть и те кто со мной согласен. Пошли они все.
Остановить счетчик можно магнитом очень большей мощности,
При этом пломбы не нарушаются. Сам счетчик не повреждается.
(если вы не лох, то вас не напугают и не разведут службы,
которые вам говорят, что, например, у вас намагнитился счетчик воды,
хотя верх у счетчика капроновый, а низ из латуни.)

И так вы уже готовы остановить свой счетчик магнитом (неодимовым)?
Такие магниты продаются на каждом углу, не верите спросите у яндекса
или вот один из Интернет магазинов по http://voda-vor.ru/magnit.html>продаже магнитов.

Помните, если вы захотели остановить счетчик газа или остановить электрический счетчик,
водяной счетчик то риск встрять в проблему всегда присутствует!

Но других вариантов как тихо заявить свой протест у вас нету!!!

Как оформить субсидию, или кому она положена вас это больше не будет
интересовать - Вы сами будете решать сколько платить.

The above are just some examples of how posts are linked over time. Do these links (and the networks they depict) constitute a conversation? This is a tricky question. The colours and the distribution over time provide some clues, but the meat of the matter has to come from text analysis. Is there a common topic that can be identified? Or, phrased otherwise, can it be determined "why" bloggers join the conversation?
