A research paper by Jarutas Pattanaphanchai, Kieron O’Hara, and Wendy Hall on a new framework to help users evaluate the trustworthiness of Web information using Semantic Web technology.
Research paper by Tope Omitola, Andre Freitas, Edward Curry, Sean O’Riain, Nicholas Gibbins and Nigel Shadbolt on a formal model of IDT (Interactive Data Transformation). IDT tools allow re-purposing of data by standardisation of heterogeneous data sets. They can also perform data quality assurance. The paper discusses the implementation and validation of the model on the IDT platform Google Refine.
A research paper by Max Van Kleek, Daniel A. Smith, Nigel R. Shadbolt and M. C. Schraefel on the problems and frustrations of using disparate systems for managing personal data. A new web-standards based architecture for consolidating personal information systems called the WebBox is proposed.
Research paper by Pattanaphanchai J., O’Hara K. and Hall W. on a new method for the evaluation of the trustworthiness of Web content which uses Semantic Web technologies. It will be presented at the International Semantic Web Conference from the 23rd to the 27th of October in Bonn, Germany.
Research paper by Igor O. Popov, M. C. Schraefel, Wendy Hall and Nigel R. Shadbolt on a new tool for exploring and displaying graph based data sets. It will be presented at the International Semantic Web Conference from the 23rd to the 27th of October in Bonn, Germany.
The 10th International Semantic Web Conference (ISWC) took place in Bonn in Germany from the 23rd to the 27th of October.
The ISWC is the leading conference on the Semantic Web. The programme included tutorials, workshops and presentations on the latest research and innovations.
In collaboration with the EnAKTing Project, Seme4 have produced See UK, a demonstrator that gives an end-user visualisation of multiple Open Datasets against a geographic background.
See UK
(http://apps.seme4.com/see-uk/)
is a simple visualisation of data that has geographic aspects
and has been published as machine-interpretable Linked Data.
See UK uses data that has been sourced from data.gov.uk and processed
into Linked Data where necessary, but is also designed to be able to use
other sources where available. All the datasets are then enriched, by
calculating area totals from point data and inferring aggregate values
for regions that do not have explicit data values, and further
enriched by establishing linkage between the datasets.
These enriched datasets are available directly from the
EnAKTing Project,
and can be accessed using the links below.
The visualisation provides a view centred on a chosen region of
specified size, and most noticeably gives a “pie-chart” that shows the
viewer how that region compares with similar regions around it. It
is thus designed to focus on the information most relevant to the
user. Colour indicates the “worst” (red) and “best” (green) areas
from those shown. This pie-chart is shown in preference to simply
colouring the map itself, as a coloured map confuses the map
features with the data being visualised.
It also gives some context of the real geography
involved, so that a full picture is seen. The user can navigate by
looking and clicking on the pie-chart, or the map, and can thus move
around using whatever view they are taking of the data presentation. A
search by postcode functionality is also supported, aiding the user in
finding specific locations.
An important aspect of the visualisation is that cross-dataset
correlation can be achieved and presented in a natural fashion, as
the data can be viewed as normalised by population or area, in
addition to the raw values. The user can therefore see how regions
compare in terms of, for example, crime density by population or
area, rather than just knowing that their county has little crime,
and guessing this is because the county has a small population or
area.
See UK has been produced as a collaborative activity between Seme4 Ltd.
and members of the EnAKTing project at the University of Southampton.
