A Hybrid Tweet Contextualization System using IR and Summarization

Pinaki Bhaskar, Somnath Banerjee, Sivaji Bandyopadhyay
2012 Conference and Labs of the Evaluation Forum  
The INEX TC task has two main sub tasks, Focused IR and Automatic Summarization. In the Focused IR system, we first preprocess the Wikipedia documents and then index them using Nutch with NE field.  ...  Stop words are removed and all NEs are tagged from each query tweet and all the remaining tweet words are stemmed using Porter stemmer.  ...  We acknowledge the support of the IFCPAR funded Indo-French project "An Advanced Platform for Question Answering Systems" and the DIT, Government of India funded project "Development of Cross Lingual Information  ...

Towards Events Tweet Contextualization Using Social Influence Model and Users Conversations

Rami Belkaroui, Rim Faiz
2015 Proceedings of the 5th International Conference on Web Intelligence, Mining and Semantics - WIMS '15  
To evaluate our approach, we construct a reference summary by asking assessors to manually select the most informative tweets as a summary.  ...  In order, to make tweet understandable to a reader, it is therefore necessary to know their context.  ...  The proposed approach in [6] described a hybrid tweet contextualization system using Information Retreival (IR) and Automatic Summarization (AS).  ...

Conversational based method for tweet contextualization

Rami Belkaroui, Rim Faiz
2017 Vietnam Journal of Computer Science  
We propose a specific method allowing to automatically contextualize tweets using information coming from social user interactions.  ...  Bound to 140 characters, tweets are short and ambiguous by nature. It can be hard for a user without any kind of context to effectively understand what the tweet is about.  ...  , and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.  ...
