Khaled Hossain Ansary, Anh Tuan Tran, Nam Khanh Tran
2013 Conference and Labs of the Evaluation Forum  
This article describes a pipeline system and preliminary results for Tweet Contextualization at INEX 2013. The system consists of three steps: tweet analysis, passage retrieval and summarization.  ...  Finally, a multi-document summarization system (MEAD) is used to generate the output document with a limit of 500 words.  ...  developed as part of the participation in the Tweet Contextualization track of INEX 2013.  ...

Statistical and Semantic Approaches for Tweet Contextualization

Meriem Amina Zingla, Latiri Chiraz, Yahya Slimani, Catherine Berrut
2015 Procedia Computer Science  
The effectiveness of our approaches is proved through an experimental study conducted on the INEX 2013 collection.  ...  The task of tweet contextualization was organized around these issues. It aims to provide an automatic readable context explaining a given tweet, in order to help the reader understand this latter.  ...  Thus, the INEX 2013 tweet contextualization track proposed to answer questions of the form "What is this tweet about?"  ...

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.  ...  This motivated the proposal in 2011 of a new track at Clef INEX lab of Tweet Contextualization.  ...

User-Tweet Interaction Model and Social Users Interactions for Tweet Contextualization [chapter]

Rami Belkaroui, Rim Faiz, Pascale Kuntz
2015 Lecture Notes in Computer Science  
To evaluate our approach, we construct a reference summary by asking assessors to manually select the most informative tweets as a summary.  ...  In this paper, we propose an approach for tweet contextualization task which combines different types of signals from social users interactions to provide automatically information that explains the tweet  ...  Recently, [10] modified the method presented at INEX 2011, 2012 and 2013 [12, 13] by adding the influence of topic-comment relationship on contextualization.  ...

Entity Retrieval and Text Mining for Online Reputation Monitoring [article]

Pedro Saleiro
2018 arXiv   pre-print
This is a challenging problem which traditional entity search systems cannot cope with.  ...  As such, we propose the inclusion of entity retrieval capabilities as a first step towards the extension of current ORM capabilities.  ...  We start by describing our participation at the Filtering task of RepLab 2013 [32] . We developed a supervised method to classify tweets as relevant or non-relevant to given target entity.  ...

Learning from User Interactions in Personal Search via Attribute Parameterization

Michael Bendersky, Xuanhui Wang, Donald Metzler, Marc Najork
2017 Proceedings of the Tenth ACM International Conference on Web Search and Data Mining - WSDM '17  
Given an event entity, we propose a graphbased framework for retrieving a ranked list of related events that a user is likely to be interested in attending.  ...  the challenge of feature sparseness and noisiness, and (b) the semantic mismatch problem in a self-contained and principled manner.  ...  In contrast, events are described by a short title, typically not stored in a knowledge base, and are present only at one, or at most a handful of web pages.  ...

These include identifying claims worth fact-checking, detecting relevant previously fact-checked claims, retrieving relevant evidence to fact-check a claim, and actually verifying a claim.  ...  These phenomena have led to the modern incarnation of the fact-checker --- a professional whose main aim is to examine claims using available evidence and to assess their veracity.  ...  Acknowledgments This work was made possible in part by grant# NPRP 7-1330-2-483 from the Qatar National Research Fund (a member of Qatar Foundation). Partial support also comes from a Google gift.  ...

Reliable and low-cost test collections construction using machine learning [article]

Rahman, Md Mustafizur (Ph. D. In Information Studies), Austin, The University Of Texas At, Matthew A. Lease, Mucahid Kutlu
I present my work in four directions: i) understanding the effects of the participating systems on the qualities of a test collection, ii) modeling a machine learning system to reduce the human annotation  ...  In the first direction, I investigate how the number of participating systems impacts the qualities of a test collection.  ...  While experimenting using the INEX test collections, Pal et al. [2011] also find that to build a reliable test collection at minimal cost, WaS judging is better than NaD judging.  ...

Discovering and disambiguating named entities in text

Johannes Hoffart

The first contribution is a robust disambiguation method using a graph algorithm that makes use of the coherence among entities in the input.  ...  A key challenge is the ambiguity of entity names, requiring robust methods to disambiguate names to canonical entities registered in a knowledge base.  ...  INEX Link-the-Wiki The initial challenge has been held as part of the INEX in 2008 [HGT08] , where the goal was to recreate Wikipedia links on a per-mention basis.  ...

Joint Discourse-aware Concept Disambiguation and Clustering

Angela Petra Fahrni
Concept disambiguation is the task of linking common nouns and proper names in a text -henceforth called mentions -to their corresponding concepts in a predefined inventory.  ...  We approach the question which context is relevant to disambiguate a mention from a discourse perspective and state that different mentions require different notions of contexts.  ...  , we report the results for the best system at TAC 2013 (Best), the median performance of all systems that participated at TAC 2013 (Median) and the results of closely related approaches.  ...
