The Role of Predicates in Opinion Holder Extraction
"... In this paper, we investigate the role of predicates in opinion holder extraction. We will examine the shape of these predicates, investigate what relationship they bear towards opinion holders, determine what resources are potentially useful for acquiring them, and point out limitations of an opini ..."

Convolution Kernels for Opinion Holder Extraction
"... Opinion holder extraction is one of the important subtasks in sentiment analysis. The effective detection of an opinion holder depends on the consideration of various cues on various levels of representation, though they are hard to formulate explicitly as features. In this work, we propose to use c ..."

Identifying Opinion Holders for Question Answering in Opinion Texts
- In Proceedings of AAAI-05 Workshop on Question Answering in Restricted Domains
, 2005
"... Question answering in opinion texts has so far mostly concentrated on the identification of opinions and on analyzing the sentiment expressed in opinions. In this paper, we address another important part of Question Answering (QA) in opinion texts: finding opinion holders. Holder identification is a ..."

Identifying Opinion Holders in Opinion Text from Online Newspapers
- In 2007 IEEE International Conference on Granular Computing
, 2007
"... We propose an anaphor resolution based opinion holder identification method exploiting lexical and syntactic information. We tested our approach on online news documents and obtained 72.22 % and 69.89 % in accuracy for the task of non-anaphoric opinion holder resolution and the task of anaphoric opi ..."

Extracting Opinions, Opinion Holders, and Topics Expressed in Online News Media Text
- In ACL Workshop on Sentiment and Subjectivity in Text. Alessandro Moschitti, Daniele Pighin, Roberto Basili
"... This paper presents a method for identifying an opinion with its holder and topic, given a sentence from online news media texts. We introduce an approach of exploiting the semantic structure of a sentence, anchored to an opinion bearing verb or adjective. This method uses semantic role labeling as ..."

Identifying opinion holders and targets with dependency parser in Chinese news texts
- in Proceedings of Human Language Technologies: The 2010 Annual Conference of the North American Chapter of the ACL
, 2010
"... In this paper, we propose to identify opinion holders and targets with dependency parser in Chinese news texts, i.e. to identify opinion holders by means of reporting verbs and to identify opinion targets by considering both opinion holders and opinion-bearing words. The experiments with NTCIR-7 MOA ..."

© The Association for Computational Linguistics and Chinese Language Processing Identification of Opinion Holders
"... Opinion holder identification aims to extract entities that express opinions in sentences. In this paper, opinion holder identification is divided into two subtasks: author’s opinion recognition and opinion holder labeling. Support vector machine (SVM) is adopted to recognize author’s opinions, and ..."

Prototypical Opinion Holders: What We can Learn from Experts and Analysts
"... In order to automatically extract opinion holders, we propose to harness the contexts of prototypical opinion holders, i.e. common nouns, such as experts or analysts, that describe particular groups of people whose profession or occupation is to form and express opinions towards specific items. We a ..."

Generalization Methods for In-Domain and Cross-Domain Opinion Holder Extraction
