MetadataVis full innførsel
When a critical event occurs, it is often challenging to get a clear overview of the event. Many sources of information such as newspapers and Twitter often contains a lot of information that is not relevant and requires a lot of reading to gain an overview of the situation. Real time temporal summarization systems is an effort to address this problem, by analysing available information in real time and producing a continuous summary as new information becomes available. The result of this thesis is a real time temporal summarization system. The system has been tested according to the requirements of the TREC 2014 Temporal Summarization track. The results have been evaluated using standard evaluation criteria and compared to the results of the 2014 participants. The system performed comparable to the best teams from 2014 and it is likely that the techniques used could be improved further by considering more aspects of the available information when summarizing an event.
