Leveraging Learning To Rank in an Optimization Framework for Timeline Summarization
نویسندگان
چکیده
With the tremendous amount of news published on the Web every day, helping users explore news events on a given topic of interest is an acute problem. Timeline summaries have recently emerge as a simple and effective solution for users to navigate through temporally related news events. In this paper, we propose an optimization framework and demonstrate the use of Learning To Rank (LTR) to automatically construct timeline summaries from Web news articles. Experimental evaluations show that our approach outperforms existing solutions in producing high quality timeline summaries. We make our dataset publicly available for future research in the same area at http://www.l3s.de/~gtran/timeline/

Timeline Summarization from Social Media with Life Cycle Models
The popularity of social media shatters the barrier for online users to create and share information at any place at any time. As a consequence, it has become increasing difficult to locate relevance information about an entity. Timeline has been proven to provide an effective and efficient access to understand an entity by displaying a list of episodes about the entity in chronological order. ...
متن کاملA Low-Rank Approximation Approach to Learning Joint Embeddings of News Stories and Images for Timeline Summarization
A key challenge for timeline summarization is to generate a concise, yet complete storyline from large collections of news stories. Previous studies in extractive timeline generation are limited in two ways: first, most prior work focuses on fully-observable ranking models or clustering models with hand-designed features that may not generalize well. Second, most summarization corpora are text-...
متن کاملLeveraging sentence weights in a concept-based optimization framework for extractive meeting summarization
We adopt an unsupervised concept-based global optimization framework for extractive meeting summarization, where a subset of sentences is selected to cover as many important concepts as possible. We propose to leverage sentence importance weights in this model. Three ways are introduced to combine the sentence weights within the concept-based optimization framework: selecting sentences for conc...
متن کاملHuman Action Attribute Learning From Video Data Using Low-Rank Representations
Representation of human actions as a sequence of human body movements or action attributes enables the development of models for human activity recognition and summarization. We present an extension of the low-rank representation (LRR) model, termed the clustering-aware structure-constrained low-rank representation (CS-LRR) model, for unsupervised learning of human action attributes from video ...
