We are looking for a post-doctoral researcher to work on the Visual Analytics techniques for  Social Media analysis (e.g., Twitter). The researcher is expected to take a leading role in designing and developing novel Visual Analytics techniques to address the data quality and uncertainty issues commonly encountered in  Social Media analysis. &#039;Provenance&#039; is expected to be an important part of the solution. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The researcher will be part of a collaboration team formed by Middlesex University, City University (Prof. Jo Wood and Prof. Jason Dykes), Loughborough University (Dr. Derek Stephens), and Defence Science and Technology Laboratory (dstl). The researcher will be based at the Interaction Design Centre within the School of Engineering and Information Sciences at the Middlesex University located in London, UK. The Centre leads the UK Visual Analytics Consortium (UKVAC) that includes Bangor University, University College London, Imperial College, and Oxford University. &lt;br /&gt;

== Short Description ==&lt;br /&gt;
{{Quotation|[...]The essence of this scheme is to lay out the hierarchy in a uniform way on a hyperbolic plane and map this plane onto a circular display region. This supports a smooth blending between focus and context, as well as continuous redirection of the focus[...] Two salient properties of the figures are: First that components diminish in size as they move outwards, and second that there is an exponential growth in the number of components. These  properties - &amp;quot;fisheye&amp;quot; distortion and the ability to uniformly embed an exponentially growing structure - are the aspects of this construction. [...]| [John Lamping et al., 1995]}}&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Suitable Datatypes ==&lt;br /&gt;
This visualization method can be used on hierarchies. With its characteristics the method is especially suitable for the visualization and manipulation of large hierachical data.&lt;br /&gt;
&lt;br /&gt;
== Figures ==&lt;br /&gt;
&lt;br /&gt;
The [http://www.mcescher.com/Gallery/recogn-bmp/LW436.jpg Circle Limit IV 1960 woodcut in black and ocre], printed from 2 blocks by [http://www.mcescher.com  Maurits Cornelis Escher] (1898-1972) was the original inspiration for the hyperbolic browser.&lt;br /&gt;
&lt;br /&gt;
The hyperbolic browser shows a tree of hierarchical information with its root initially in the center, but the display can be transformed to bring other nodes into focus. &lt;br /&gt;
The following figure shows an original hyperbolic tree with its origin in the center and 1004 nodes:&lt;br /&gt;
&lt;br /&gt;
[[Image:Hyptree original.jpg]]&lt;br /&gt;
&lt;br /&gt;
The origin does not have to be in the center of the fisheye as written above. The focus can be changed by the user either by clicking on any visible point to bring it into focus at the center or by dragging any visble point interactively to any other position:&lt;br /&gt;
&lt;br /&gt;
[[Image:HypTree changinfocus.jpg]] &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Examples and use cases == &lt;br /&gt;
[[Image:Roget2000.jpg|thumb|Visualization of Roget Thesaurus using the IV XML Toolkit. ]]&lt;br /&gt;
&lt;br /&gt;
Hyperbolic trees are often used to display webinformation. Therefore hyperbolic browsers were developed which support effective interaction with much lager hierarchies than conventional hierarchy viewers and complements the strengths of other novel tree browsers. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Comparison:&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
If you have a window of 600x600px a standard 2d-hierarchy browser can usually display 100 with 3 character text strings. The hyperbolic browser can display 1000 nodes in this area and about the 50 nearest to the focus can display from 3 up to dozens of characters of text.&lt;br /&gt;
&lt;br /&gt;
So the big advantage of hyperbolic tree browsers is the possibility to display a big amount of hierarchical information within a small space without a loss of focus and context. &lt;br /&gt;

&lt;br /&gt;
== Short Description ==&lt;br /&gt;
{{Quotation|[...]The essence of this scheme is to lay out the hierarchy in a uniform way on a hyperbolic plane and map this plane onto a circular display region. This supports a smooth blending between focus and context, as well as continuous redirection of the focus[...] Two salient properties of the figures are: First that components diminish in size as they move outwards, and second that there is an exponential growth in the number of components. These  properties - &amp;quot;fisheye&amp;quot; distortion and the ability to uniformly embed an exponentially growing structure - are the aspects of this construction. [...]| [John Lamping et al., 1995]}}&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Suitable Datatypes ==&lt;br /&gt;
This visualization method can be used on hierarchies. With its characteristics the method is especially suitable for the visualization and manipulation of large hierachical data.&lt;br /&gt;
&lt;br /&gt;
== Figures ==&lt;br /&gt;
&lt;br /&gt;
The [http://www.mcescher.com/Gallery/recogn-bmp/LW436.jpg Circle Limit IV 1960 woodcut in black and ocre], printed from 2 blocks by [http://www.mcescher.com  Maurits Cornelis Escher] (1898-1972) was the original inspiration for the hyperbolic browser.&lt;br /&gt;
&lt;br /&gt;
The hyperbolic browser shows a tree of hierarchical information with its root initially in the center, but the display can be transformed to bring other nodes into focus. &lt;br /&gt;
The following figure shows an original hyperbolic tree with its origin in the center and 1004 nodes:&lt;br /&gt;
&lt;br /&gt;
[[Image:Hyptree original.jpg]]&lt;br /&gt;
&lt;br /&gt;
The origin does not have to be in the center of the fisheye as written above. The focus can be changed by the user either by clicking on any visible point to bring it into focus at the center or by dragging any visble point interactively to any other position:&lt;br /&gt;
&lt;br /&gt;
[[Image:HypTree changinfocus.jpg]] &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Examples and use cases == &lt;br /&gt;
[[Image:Roget2000.jpg|thumb|Visualization of Roget Thesaurus using the IV XML Toolkit. ]]&lt;br /&gt;
&lt;br /&gt;
Hyperbolic trees are often used to display webinformation. Therefore hyperbolic browsers were developed which support effective interaction with much lager hierarchies than conventional hierarchy viewers and complements the strengths of other novel tree browsers. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Comparison:&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
If you have a window of 600x600px a standard 2d-hierarchy browser can usually display 100 with 3 character text strings. The hyperbolic browser can display 1000 nodes in this area and about the 50 nearest to the focus can display from 3 up to dozens of characters of text.&lt;br /&gt;
&lt;br /&gt;
So the big advantage of hyperbolic tree browsers is the possibility to display a big amount of hierarchical information within a small space without a loss of focus and context. &lt;br /&gt;

We are looking for a post-doctoral researcher to work on the Visual Analytics techniques for  Social Media analysis (e.g., Twitter). The researcher is expected to take a leading role in designing and developing novel Visual Analytics techniques to address the data quality and uncertainty issues commonly encountered in  Social Media analysis. &#039;Provenance&#039; is expected to be an important part of the solution. &lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
The researcher will be part of a collaboration team formed by Middlesex University, City University (Prof. Jo Wood and Prof. Jason Dykes), Loughborough University (Dr. Derek Stephens), and Defence Science and Technology Laboratory (dstl). The researcher will be based at the Interaction Design Centre within the School of Engineering and Information Sciences at the Middlesex University located in London, UK. The Centre leads the UK Visual Analytics Consortium (UKVAC) that includes Bangor University, University College London, Imperial College, and Oxford University. &lt;br /&gt;
