We use SVM classifiers to predict the next action of a deterministic parser that builds labeled projective dependency graphs in an incremental fashion. Non-projective dependencies are captured indirectly by projectivizing …...

HIT-IR-WSD is a word sense disambigua- tion (WSD) system developed for English lexical sample task (Task 11) of Semeval 2007 by Information Retrieval Lab, Harbin Institute of Technology. The system …...

Financial investors trade on the basis of infor- mation, and in particular, on the likelihood that a piece of information will impact the mar- ket. The ability to predict this …...

This paper employs morphological struc- tures and relations between sentence seg- ments for opinion analysis on words and sentences. Chinese words are classified into eight morphological types by two proposed …...

We present disputant relation-based meth- od for classifying news articles on conten- tious issues. We observe that the disputants of a contention are an important feature for understanding the discourse. …...

This paper briefly reports our system for the SemEval-2013 Task 2: sentiment analysis in Twitter. We first used an SVM classifier with a wide range of features, including bag of …...

This paper describes the system implemented by Fundaci´o Barcelona Media (FBM) for clas- sifying the polarity of opinion expressions in tweets and SMSs, and which is supported by a UIMA …...

In this paper, we describe how we created two state-of-the-art SVM classifiers, one to de- tect the sentiment of messages such as tweets and SMS (message-level task) and one to …...

In this paper we describe our system submit- ted for evaluation in the CLTE-SemEval-2013 task, which achieved the best results in two of the four data sets, and finished third …...

In this paper we propose a two-stage method to acquire contradiction relations between typed lexico-syntactic patterns such as Xdrug prevents Ydisease and Ydisease caused by Xdrug. In the first stage, …...

This paper presents the approach of the CISUC-KIS team to the SemEval 2014 task on Sentiment Analysis in Twitter, more precisely subtask B - Message Polar- ity Classification. We followed …...

This paper describes the system we sub- mitted to the SemEval-2014 shared task on sentiment analysis in Twitter. Our sys- tem is a hybrid combination of two system developed for …...

Information in visually rich formats such as PDF and HTML is often conveyed by a combination of textual and visual features. In particular, genres such as marketing flyers and info-graphics …...

AbstractPrepositional phrase (PP) attachment disambiguation is a known challenge in syntactic parsing. The lexical sparsity associated with PP attachments motivates research in word representations that can capture pertinent syntactic and …...

This paper describes the system used in Task-7 (Analysis of Clinical Text) of SemEval-2014 for detecting disorder men- tions and associating them with their re- lated CUI of UMLS1. For …...

We describe the submission of the team of the Sofia University to SemEval-2014 Task 9 on Sentiment Analysis in Twit- ter. We participated in subtask B, where the participating systems …...

structures from which the generation naturally starts often do not contain any func- tional nodes, while surface-syntactic struc- tures or a chain of tokens in a linearized tree contain all …...

In this paper, we propose a baseline message- level sentiment classification method, as de- veloped for SemEval-2015 Task 10, Subtask B. This system leverages both hand-crafted features and message-level embedding …...

Determining whether a major societal event has already happened, is still on-going, or may occur in the future is crucial for event pre- diction, timeline generation, and news sum- marization. …...

This paper describes our proposed solutions designed for a STS core track within the Se- mEval 2016 English Semantic Textual Sim- ilarity (STS) task. Our method of similar- ity detection …...

Automatic document classification is now a growing research topic in Natural Language Processing. Several techniques were incorporated to build a classifier that can categorize documents written in specific languages into …...

AbstractThe article describes a model of automatic interpretation of English puns, based on Roget’s Thesaurus, and its implementation, PunFields. In a pun, the algorithm discovers two groups of words that …...

AbstractThe “Capturing Discriminative Attributes” sharedtask is the tenth task, conjoint with SemEval2018. The task is to predict if a word can capture distinguishing attributes of one word from another. We …...

AbstractWe present the system built for SemEval-2018 Task 2 on Emoji Prediction. Although Twitter messages are very short we managed to design a wide variety of features: textual, semantic, sentiment, …...

AbstractThis paper summarizes our contribution to the Hyperpartisan News Detection task in SemEval 2019. We experiment with two different approaches: 1) an SVM classifier based on word vector averages and …...

AbstractIn this paper, we describe our attempt to learn bias from news articles. From our experiments, it seems that although there is a correlation between publisher bias and article bias, …...

AbstractThis paper describes our submission to SemEval-2019 Task 12 on toponym resolution over scientific articles. We train separate NER models for toponym detection over text extracted from tables vs. text …...

AbstractAuthorship attribution infers the likely author of an unsigned, single-authored document from a pool of candidates. Despite recent advances, a lack of standard, reproducible testbeds for Chinese language documents impedes …...
