Ingeniería de rendimiento web basada en ontologías y web semántica

Sobre la calidad de las publicaciones que tendríamos que considerar a partir de ahora (aconsejo por su sencillez CORE):

“…los trabajos publicados en revistas de reconocida valía, aceptándose
como tales las que ocupen posiciones relevantes en los listados por
ámbitos científicos en el «Subject Category Listing» del «Journal Citation
Reports» del «Science Citation Index» (Institute for Scientific Information,
–ISI– Philadelphia, PA, USA). Las revistas electrónicas se considerarán
cuando aparezcan en los listados del ISI o satisfagan los criterios…
… los trabajos publicados en las actas de congresos que posean un
sistema de revisión externa por pares, cuando estas actas sean vehículo
de difusión del conocimiento comparable a las revistas internacionales de
prestigio reconocido. Se aceptarán como tales los trabajos publicados en
las actas de los congresos que ocupen posiciones suficientemente relevantes
en los listados de los índices CiteSEER (http://citiseer.ist.psu.edu/impact.html), Computing Research and Education (CORE) (http://www.core.edu.au/) o
CS Conference Rankings (http://www.cs-conference-ranking.org/conferencerankings/alltopics.html).”

During my speech in the CEDI and listening some other speechs I have had some ideas and sugestions.

1. Working with fragments in a web page, we have the risk of get higher response times in the server because the database conections. For each fragment a diferent DB connection is required and that is the part that takes a bigger time in a DB transaction. Need to do an experiment.
2. Working with the source code of web applications is very intrusive. It could be better work directly in the html code generated. Could we enought the information extract from the HTML code for our propouse. In first sight I’ll thing it isn’t, because we need to execute only parts of the sourcecode. Spliting the HTML we won’t be able to execute differents parts of the source code. Need to be studied.

3. Interesting the portslets JAVA technology to be applied to my research work.

4. If it’s possible to identify fragments that technique could be apply to the field of adapting that fragment contents automatically from web sites to mobile devices.

5. Juan Ignacio Vazquez presents the article “Principles and experiences on creating semantic devices”. He explained something about the devices creates wiki systems and cooperative enviroments that other devices use when get into the enviroment using the past experience of the others device. He called it something like device 2.0 (as web 2.0). I think could be an idea I could apply.

Here you can donwload my presentation for the research meeting with the Paderborn University.

Next week a research meeting will take place in the UIB with the visit of a group of the Paderborn University. The research groups are: Distributed Embedded Real-Time Systems (UP); Systems, Robotics and Vision (UIB) and Architecture and Performance of Computer and Communications Systems (UIB).

I’m preparing a presentation for this meeting with the global idea and aim of my PhD Degree. Next week I’ll upload it and I would glad all the possible suggestions made.

The main way to improve the response time of a dinamic web site is caching. If we have cached a copy of the request made by the user is not necessary to create the page again with the scripting language and accesing to the database.

Nowadays the number of webs which pages are very similar between then and that are updating along the time with little changes, for example weblogs, news sites, … are getting higher. If our minimal cache unit is a page, with each changes the cached pages get invalid. If we make the minimal cache size less than pages, we can solve this situation.

Edge Side Includes (ESI) gives the way to define parts of a page. If we cache this parts instead of the whole page, the number of invalidations will be smaller.
