AHTOM - Asynchronous and Heterogeneous Topic Mining

The project will develop a set of models and respective software tools for topic mining of asynchronous and heterogeneous streams that will enable: (a) the discovery of a set of topics expressed by heterogeneous documents in multiple streams; (b) the quantification of the similarity between documents in terms of content re-use; (c) the tracking of the flow and changes of content over time; and (d) the discovery of significant temporal dependencies among the streams, providing quantitative measures of the importance, authoritativeness and timeliness of each stream in relation to a topic or set of topics.
