Active learning in annotating micro-blogs dealing with e-reputation [article]

Jean-Valère Cossu, Alejandro Molina-Villegas, Mariana Tello-Signoret
2017 arXiv   pre-print
Opinion and trend mining on micro blogs dealing with politics has recently attracted researchers in several fields including Information Retrieval and Machine Learning (ML).  ...  We therefore review state of the art NLP-based ML algorithms to automatically annotate tweets using a manual initiation step as bootstrap.  ...  While for a machine a word sequence will match a unique model or a weighted number of models, the language acquisition skills of humans result to a multidimensional experience.  ...

Opinion retrieval from blogs

Wei Zhang, Clement Yu, Weiyi Meng
2007 Proceedings of the sixteenth ACM conference on Conference on information and knowledge management - CIKM '07  
We implemented the algorithm as a working system and tested it using TREC 2006 Blog Track data in automatic title-only runs.  ...  It has a traditional information retrieval (IR) component to find topic relevant documents from a document set, an opinion classification component to find documents having opinions from the results of  ...  Theoretically, any document retrieval system fits here, such as the Okapi formula based systems or the systems based on various language models.  ...

Knowledge Transfer and Opinion Detection in the TREC 2006 Blog Track

Hui Yang, Jamie Callan, Luo Si
2006 Text Retrieval Conference  
The paper describes the opinion detection system developed in Carnegie Mellon University for TREC 2006 Blog track. The system performed a two-stage process: passage retrieval and opinion detection.  ...  Due to lack of training data for the TREC Blog corpus, online opinion reviews provided in other domains, such as movie review and product review, were used as the training data.  ...  Any opinions, findings, conclusions, or recommendations expressed in this paper are the authors', and do not necessarily reflect those of the sponsor.  ...

The TREC distributed opinion-finding medians for each topic are computed over all runs (baselines + opinion-finding runs, i.e. 191+41 = 232 runs).  ...  We consider that including the baseline runs in the computation of the medians would be inappropriate, as these baseline runs were not intended to retrieve opinionated documents.  ...  Acknowledgements The description of system runs are based on paragraphs contributed by the participating groups.  ...

Comparing semantic associations in sentences and paragraphs for opinion detection in blogs

Malik Muhammad Saad Missen, Mohand Boughanem, Guillaume Cabanac
2009 Proceedings of the International Conference on Management of Emergent Digital EcoSystems - MEDES '09  
In this work we revise our previous approach that combines document level heuristics with a semantic similarity based method.  ...  A review of the reveals that researchers have been working on different levels of granularity like documents, passages, sentences and words for the task of opinion detection.  ...  As we see that passage-based model is working well so we have plan to extend it further using more robust IR models.  ...

Exploring Traits of Adjectives to Predict Polarity Opinion in Blogs and Semantic Filters in Genomics

Miguel E. Ruiz, Ying Sun, Jianqiang Wang, Hongfang Liu
2007 Text Retrieval Conference  
For the BLOG track we explored the use of adjectives with in a post as a way to predict opinion polarity.  ...  This paper presents the results of our team in the Genomics and Blog tracks in TREC 2007. We used the language model implementation provided by Indri for both tracks.  ...  However, we still need to do some more work on analyzing the results to find a better model that can consistently do a better job on reranking passages using semantic information.  ...

Based on a corpus of 40 vlogs, this research categorizes different kinds of common pointing actions in vlogs.  ...  AbstractVideo blogs are a form of CMC (computer-mediated communication) that feature speakers who talk into a camera, and thereby produce a viewer-directed performance.  ...  These statements reflect two currents in genre theoretical studies, a form based and a function based approach (cf. discussion of Discourse Analytic approaches below).  ...
