Developing Multitouch Table Applications – Slides

In my presentation I introduced some concepts of Developing Multitouch Table Applications. The slides contains a short description about the underlying hardware technologies. As the platform for the implementation of my prototype I decided to use Microsoft Surface SDK. Description of the it’s architecture contains also in my presentation.

Tools and libraries for visualization

Here are some tools and libraries that can be used in our project.

TileMill is a free application for making maps and visualization of geospatial data.

TileMill: Adding data from Development Seed on Vimeo.

Such visualization is possible to make with d3.js library. It can be used for visualization of bibliographic coupling for example.

Visual Analytics – Slides

In the seminar phase I considered theoretical bases of Visual Analytics and those aspects of it, which will be applied in our project. In particular: geospatial and time factor visualization, plagiarism visualization, social networks visualization, visualization of scientific collaboration, perception and cognitive aspects. Additionally, I offered some ideas on what can be implemented during the project group.

Seminar Slides: Trend Detection and Visualization and Custom Search Applications

In my seminar, I explained trend detection in numbers and in text along with its visualization. I underlined few methods viz. Simple Moving Average(SMA) and Exponential Moving Average(EMA) to achieve trend detection in numbers and provided a prototype visualizing the same. I introduced you to the possible approaches to achieve trend detection in text. In the later part, I discussed Custom Search Application, Apache Solr and its features and provided a demonstration of its basic operations. Lastly, I briefly introduced the topics Semantic search and Linked data approach and its extension to Solr using Linked Media Framework.

Scientific Recommender Systems – Slides

Here are the slides from my presentation last week. I talked about (scientific) recommender systems in general, the three categories they can be classified into (content-based, collaborative, hybrid) and I showed some examples of algorithms and applications (TF-IDF, Apache Mahout, SciPlore) where such recommender systems are used.

Reference quality and using BibTeX for reference management

For the project group, please make sure that you cite references of high quality (read: books, journal articles or conference proceedings). Wikipedia is a very good entry point for each and any topic but you should look for “better” references when it comes to citing some work. We all know about the discussion on quality differences in Wikipedia compared to other encyclopedias but you should also try to look beyond Wikipedia.

Regarding the reference management in your paper, you will have to use BibTeX. The references are stored in the .bib file I provided. Have a look at this page for learning which fields are required for which kind of reference. As a rule of thumb you need to remember that each reference needs at least

  • year of publication
  • title
  • name of the authors

I highly recommend that you use a reference manager like BibDesk (Mac) or JabRef (Linux, Windows, Mac).

When you cite online resources, please use the @misc BibTeX type. The URL of the site goes into “howpublished” together with the date of access. Here are two examples:

Author = {Moore, C. and Rugullies, E.},
Howpublished = {Available online \url{} accessed 28.10.2010},
Title = {{The Information Workplace Will Redefine The World Of Work At Last}},
Year = {2005}}
Author = {Crowdsourced},
Howpublished = {Available online \url{} (accessed 31 December 2010)},
Month = {December},
Title = {{Deletionism and inclusionism in Wikipedia}},
Year = {2010}}

The second example also shows how you should deal with user-generated content. First, the author of such content should be set to “crowdsourced” and second, you should try to link to a permanent URL. In the case of Wikipedia this is achieved by selecting “permanent link” in the “toolbox” section of the left navigation (e.g.
