Hola soy Fernando, disfruto investigando sobre recuperación de información y el fenómeno "information overload". Armo este blog por tres razones: a)la práctica: necesito disponer de un espacio donde pueda almacenar mis notas de estudio (reflexiones, traducciones, estadísticas) b)la social: me gustaría exponer y debatir, en forma de literatura gris, algunas ideas sobre mi temas de investigación y c)la personal: he descubierto que me gusta escribir.
Cuando me enamoraba de una Venus
mis sentimientos no eran informáticos,
pero ahora debo pedir permiso
hasta para escribir con el news gothic.
Te urjo amor que cambies de formato.
Prefiero recibirte en times new roman
más nada es comparable a aquel desnudo
que era tu signo en tiempos de la Remington.
Mario Benedetti, Antología de Poesía Hispanoamericana
1. Stanley Milgram´s Obedience Studies
In this Yale University study, participants were told they were part of an experiment on the effects of punishment [wiki] on learning. They were instructed to teach another participant (the “learner”) a list of words, and whenever the learner made a mistake, deliver an electric shock via a generator with levers labeled in 15-volt increments (up to 450 volts–where the label read “Danger: Severe Shock” and “XXX”).
The learner (who, unknown to the participant, was not actually receiving shocks) became increasingly vocal, at one point even screaming, “I can’t stand the pain! Get me out of here!” Because the experimenter urged the participants to continue, nearly 65% of them continued to obey the experimenter to deliver the maximum 450 volts. The participants weren’t sadistic, Milgram [wiki] argued, just socialized to obey authority figures.
In just a few short days, the guards began to devise sadistic and degrading rituals for the prisoners, many of whom became depressed, anxious, or apathetic. Although they knew that this was just an experiment, all of
the guards and prisoners adopted their rules, completely overriding their own individuality. The outcome was so dramatic, the experiment was stopped after only six days.
Before the experiment, Little Albert was a normal baby who was afraid of loud noises but not much else. Little Albert loved playing with small animals until Watson taught him to become afraid of a white rat by repeatedly banging a steel rod with a hammer whenever Albert was given a white rat to play with. Little Albert’s fear generalized to other similar objects, such as Watson’s white hair and a Santa Claus mask. Watson clearly demonstrated that fears could be conditioned, but his methods have been roundly criticized, especially since conditioning was never reversed.
Social information retrieval (SIR) refers to a family of techniques that assist users in obtaining information to meet their information needs by harnessing the knowledge or experience of other users. Examples of SIR techniques include sharing of queries, collaborative filtering, social network analysis, social navigation, social bookmarking and the use of subjective relevance judgements such as tags, annotations, ratings and evaluations.
SIR methods, techniques and systems open an interesting new approach to facilitate and support learning and teaching. There are plenty a resource available on the Web, both in terms of digital learning content and people resources (e.g. other learners, experts, tutors) that can be used to facilitate teaching and learning tasks. The remaining challenge is to develop, deploy and evaluate systems that provide learners and teachers with guidance to help identify suitable learning resources from a potentially overwhelming variety of choices.
Several questions are being researched around the application of SIR methods in Technology-Enhanced Learning (TEL) settings. The aim of the SIRTEL'07 Workshop is to bring together researchers and practitioners who are working on topics related to the application of SIR methods, techniques and systems in educational settings, as well as to present the current status of research in this area to interested researchers and practitioners. It aims to serve as a discussion forum where researchers will present the results of their work, and also establish liaisons between different groups that are exploring related subjects. In addition, it aims to outline the rich potential of emerging SIR methods, techniques and systems in order to better build TEL systems and services.
The aim of the workshop is to chart out the current state-of-the-art of SIR in TEL, and to list the main enablers and challenges for the near future and the long term. Each presenter of the workshop is asked to explicitly identify such enablers and challenges. The workshop will conclude with an open discussion listing and prioritising the main enablers and challenges for the short and the long term. One of the aims is to identify the need for new research.
Del estudio se desprende que el 83% de jóvenes de entre 15 y 24 años son usuarios habituales de las nuevas tecnologías, y que en esta franja de edad está disminuyendo la diferencia de género en el uso de Internet.

The Society for New Communications Research (SNCR) has a survey out:
Blogs are now a near second to newspapers as the most trusted information source. A Pew Internet and American Life survey showed that blog readership in the US jumped 58% in 2005 spawning a new desire for immediate news and information. With the launch of MySpace News (www.news.myspace.com) news has taken a leap into social media sites.
We want to find out if influential bloggers like yourself are incorporating, or are planning to incorporate news on your blog and also get your views on news sources. Please take a few minutes to give us your insights into how you would prefer to receive and use news content.

Para aquellos que deseen practicar con ER les dejo una herramienta educativa llamada Regex Coach (http://www.weitz.de/regex-coach) la cual permite construir expresiones y verificar su funcionamiento a partir del ingreso de cadenas a procesar. A los efectos de ganar tiempo les dejo a continuación una serie de tips para empezar a entender y probar la técnica:
La Escuela de Ciencias Informáticas (Departamento de Computación - Facultad de Ciencias Exactas y Naturales - Universidad de Buenos Aires) se lleva a cabo durante los meses de julio o agosto desde el año 1987.
La ECI tiene como objetivo prioritario ofrecer a nuestros alumnos, a los alumnos de otras instituciones, a graduados y a profesionales del medio cursos de especialización y actualización intensivos de alto nivel sobre temas que habitualmente no se dan en las carreras de grado. Estos cursos son dictados en su mayoría por profesores de otras instituciones, extranjeras y nacionales, lo cual permite brindar a los participantes enfoques diferentes de los temas tratados y la oportunidad de establecer vínculos de cooperación académica, así como incentivar las actividades de investigación y desarrollo en el ámbito de las universidades.
Coincidiendo con un esfuerzo nacional para crear una capacidad científica y tecnológica propia en el área informática, se intenta promover la formación de una nueva generación de investigadores y profesionales. A las distintas ediciones de la ECI han concurrido entre 350 y 800 personas que tomaron 2 o 3 cursos cada una y entre ellas se cuentan numerosos estudiantes de universidades del interior del país.
La ECI ofrece cada año entre 6 y 10 cursos intensivos de 15 a 18 horas cada uno con evaluación final. Se otorga certificado de asistencia y/o aprobación. Se provee a los alumnos material bibliográfico relacionado con el tema de cada curso.Por otro lado también se realizan durante la ECI conferencias, tutoriales y seminarios de menor duración en forma paralela a lo anterior y sin evaluación. Algunos de estos están específicamente dirigidos a profesionales que trabajan en empresas.
The first approach has the advantages of building on prerequisite knowledge, of presenting the historical development of the discipline, and probably appears more natural to most lecturers, who have followed the historical development of the field.
Conversely, the second approach has the advantage of concentrating on a more modern view of the field, and probably leads to a higher motivation in the students, since the more appealing Web issues are dealt with at course start.
I will discuss these issues, I will mention the approaches followed in the (rather few) Web IR books available, I will make some comparisons with the teaching of related disciplines, and I will also summarize my experience and some feedback from my students (I have been teaching a Web IR course for two Master's degrees in Computer Science and Information Technology at Udine University for the last two years; I had about twenty students each year; and I followed the first approach)."

Duro, pero este tipo de noble provocación, por lo menos en mi, genera un debate interno.".. Que las empresas tengan especial influencia en la política significa que la democracia está enferma. El propósito de la democracia es asegurarse de que los ricos no tienen una influencia proporcional a su riqueza. Y si tienen más influencia que tu o que yo, eso significa que la democracia está fallando. Las leyes que obtienen de esta forma no tienen autoridad moral, sino la capacidad de hacer daño..."
