Abstract
This paper presents an annotation scheme for adding entity and event target annotations to the MPQA corpus, a rich span-annotated opin-ion corpus. The new corpus promises to be a valuable new resource for developing sys-tems for entity/event-level sentiment analysis. Such systems, in turn, would be valuable in NLP applications such as Automatic Question Answering. We introduce the idea of entity and event targets (eTargets), describe the an-notation scheme, and present the results of an agreement study. 1

Towards answering opinion questions
1,051 Citations2003Hong Yu, Vasileios Hatzivassiloglou

A Joint Model of Text and Aspect Ratings for Sentiment Summarization
638 Citations2008Ivan Titov, Ryan McDonald
A statistical model is proposed which is able to discover corresponding topics in text and extract textual evidence from reviews supporting each of these aspect ratings, a fundamental problem in aspect-based sentiment summarization.

623 Citations2024Lev Ratinov
This work analyzes approaches that utilize information from Wikipedia link structure to arrive at coherent sets of disambiguations for a given document, and compares them to more traditional (local) approaches.
Learning with compositional semantics as structural inference for subsentential sentiment analysis
333 Citations2008Yejin Choi, Claire Cardie
A novel learning-based approach that incorporates structural inference motivated by compositional semantics into the learning procedure is presented, and it is found that expression-level classification accuracy uniformly decreases as additional, potentially disambiguating, context is considered.
Structured Models for Fine-to-Coarse Sentiment Analysis
286 Citations2007Ryan McDonald, Kerry Hannan +3 more
Experiments show that this structured model for jointly classifying the sentiment of text at varying levels of granularity can significantly reduce classification error relative to models trained in isolation.

137 Citations2008Theresa Wilson
This dissertation investigates the manual and automatic identification of linguistic expressions of private states in a corpus of news documents from the world press with results in automatic systems for performing fine-grained subjectivity analysis that significantly outperform baseline systems.
Multi-perspective question answering using the OpQA corpus
135 Citations2005Veselin Stoyanov, Claire Cardie +1 more
It is argued that traditional fact-based QA approaches may have difficulty in an MPQA setting without modification, and the use of machine learning and rule-based subjectivity and opinion source filters are investigated and shown that they can be used to guideMPQA systems.
Annotating Opinions in the World Press

Computational LinguisticsRelational Features in Fine-Grained Opinion Analysis
68 Citations2012Richard Johansson, Alessandro Moschitti
A set of experiments are described that demonstrate that relational features, mainly derived from dependency-syntactic and semantic role structures, can significantly improve the performance of automatic systems for a number of fine-grained opinion analysis tasks: marking up opinion expressions, finding opinion holders, and determining the polarities of opinion expressions.
