i-sieve Technologies - Projects
i-sieve is an active participant in a number of projects, past and present.
We are always interested in pursuing new projects where sentiment analysis and/or metadata describing websites are a key part of the work.
Personalised Access to Cultural Heritage Spaces
January 2011 - December 2013
Significant amounts of cultural heritage material are now available through online digital library portals. However, this vast amount of cultural heritage material can also be overwhelming for many users who are provided with little or no guidance on how to find and interpret this information. The situation is very different in museums and galleries where items are organised thematically and users guided through the collection.
The PATHS project will create a system that acts as an interactive personalised tour guide through existing digital library collections. The system will offer suggestions about items to look at and assist in their interpretation. Navigation will be based around the metaphor of a path through the collection. A path can be based around any theme, for example artist and media (paintings by Picasso), historic periods (the Cold War), places (Venice) and famous people (Muhammad Ali). Users will be able to construct their own paths or follow pre-defined ones.
i-sieve is using its focussed Web crawler/spider combination to identify resources on the Web that are relevant to the various items in the professionally curated collections. In addition, i-sieve's sentiment analysis technology is being put to work assessing user experiences of cultural heritage resources.
PATHS is funded by the European Commission FP7 under the Digital Libraries and Digital Preservation programme which started on January 1st 2010 and runs for three years.
April 2009 - March 2012
Traditionally, opinions on public issues are communicated to mass audiences only through the established news media. The advent of internet has provided to every citizen an inexpensive channel for broadcasting information to large audiences. However, this potential has yet to be fully exploited. SYNC3 aspires to provide the means by everyone will be able to take part in the formation of public opinion in a broader scale than the boundaries of narrow social surroundings permit.
SYNC3, Synergetic Content Creation & Communication, focuses in the commentaries of blog users on issues that are presented in the news media (blogosphere content). Such content is of significant importance for the collective formation of public opinion. However, blogs have yet to take place as a primary source of information. But unlike community news portals, the blogosphere is largely unstructured. This constitutes the main reason that the blogosphere cannot consistently reach larger audiences.
i-sieve's focussed Web crawling, spidering and sentiment analysis technolgy plays an important part in the identification and collation of user-generated 'news' by identifying and aggregating blogs expressing similar viewpoints.
October 2007 - Setpember 2009
The Quality and Content Description project ran for 2 years between October 2007 and September 2009. the central themse was identifying online resources that meet certain criteria. There are many organisations that assess websites based on a set of criteria and award a seal of approval to those content providers that meet the criteria. That's not how people think of it, but that's the essence of what a trustmark does. QUATRO enables trustmarks and other sources of expert opinion to be machine processable.
As part of its contribution to the Quatro Plus project, i-sieve lead the development of a new web standard known as POWDER (the Protocol for Web Description Resources) under the W3C Recommendation process. Key POWDER tools are available elsewhere on this website including the validator and processor.
NCSR Demokritos, the research centre with which i-sieve is closely associated, has been leading the development of a suite of applications that use POWDER to create, manage, process and authenticate trustmarks.
