    Automated Detection of Usage Errors in non-native English Writing

    In an investigation of the use of a novelty detection algorithm for identifying inappropriate word combinations in a raw English corpus, we employ an unsupervised detection algorithm based on the one- class support vector machines (OC-SVMs) and extract sentences containing word sequences whose frequency of appearance is significantly low in native English writing. Combined with n-gram language models and document categorization techniques, the OC-SVM classifier assigns given sentences into two different groups; the sentences containing errors and those without errors. Accuracies are 79.30 % with bigram model, 86.63 % with trigram model, and 34.34 % with four-gram model

    Parsing Argumentation Structures in Persuasive Essays

    Full text link
    In this article, we present a novel approach for parsing argumentation structures. We identify argument components using sequence labeling at the token level and apply a new joint model for detecting argumentation structures. The proposed model globally optimizes argument component types and argumentative relations using integer linear programming. We show that our model considerably improves the performance of base classifiers and significantly outperforms challenging heuristic baselines. Moreover, we introduce a novel corpus of persuasive essays annotated with argumentation structures. We show that our annotation scheme and annotation guidelines successfully guide human annotators to substantial agreement. This corpus and the annotation guidelines are freely available for ensuring reproducibility and to encourage future research in computational argumentation.Comment: Under review in Computational Linguistics.

This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving."[EN] The possibility of knowing people traits on the basis of what they write is a field of growing interest named author profiling. To infer a user's gender, age, native language, language variety, or even when the user lies, simply by analyzing her texts, opens a wide range of possibilities from the point of view of security. In this paper, we review the state of the art about some of the main author profiling problems, as well as deception and irony detection, especially focusing on the Arabic language.Qatar National Research Fund, Grant/Award Number: NPRP 9-175-1-033Rosso, P.; Rangel-Pardo, FM.; Hernandez-Farias, DI.; Cagnina, L.; Zaghouani, W.; Charfi, A.

    PersoNER: Persian named-entity recognition

    Full text link
    © 1963-2018 ACL. Named-Entity Recognition (NER) is still a challenging task for languages with low digital resources. The main difficulties arise from the scarcity of annotated corpora and the consequent problematic training of an effective NER pipeline. To abridge this gap, in this paper we target the Persian language that is spoken by a population of over a hundred million people world-wide. We first present and provide ArmanPerosNERCorpus, the first manually-annotated Persian NER corpus. Then, we introduce PersoNER, an NER pipeline for Persian that leverages a word embedding and a sequential max-margin classifier. The experimental results show that the proposed approach is capable of achieving interesting MUC7 and CoNNL scores while outperforming two alternatives based on a CRF and a recurrent neural network

    MoBiL: A hybrid feature set for Automatic Human Translation quality assessment

    Get PDF
    In this paper we introduce MoBiL, a hybrid Monolingual, Bilingual and Language modelling feature set and feature selection and evaluation framework. The set includes translation quality indicators that can be utilized to automatically predict the quality of human translations in terms of content adequacy and language fluency. We compare MoBiL with the QuEst baseline set by using them in classifiers trained with support vector machine and relevance vector machine learning algorithms on the same data set. We also report an experiment on feature selection to opt for fewer but more informative features from MoBiL. Our experiments show that classifiers trained on our feature set perform consistently better in predicting both adequacy and fluency than the classifiers trained on the baseline feature set. MoBiL also performs well when used with both support vector machine and relevance vector machine algorithms

    Designing, implementing, and evaluating an automated writing evaluation tool for improving EFL graduate students’ abstract writing: a case in Taiwan

    Get PDF
    Writing English research article (RA) abstracts is a difficult but mandatory task for Taiwanese engineering graduate students (Feng, 2013). Understanding the current situation and needs of Taiwanese engineering graduate students, this dissertation aimed to develop and evaluate an automated writing evaluation (AWE) tool to assist their research article (RA) abstract writing in English by following a Design-Based Research (DBR) approach as the methodological framework. DBR was chosen because it strives to solve real-world problems through multiple iterations of development and building on results from each iteration to advance the project. Six design iterations were undertaken to develop and to evaluate the AWE tool in this dissertation, including (1) corpus compilation of engineering RAs, (2) genre analysis of engineering abstracts, (3) machine learning of move classification in abstracts, (4) analysis of lexical bundles used to express moves, (5) analysis of the choice of verb categories associated with moves, and finally, (6) AWE tool development based on previous findings, classroom implementation, and evaluation of the AWE tool following Chapelle’s (2001) computer-assisted language learning (CALL) framework. To begin with, I collected a corpus of 480 engineering RAs (Corpus-480) to extract appropriate linguistic properties as pedagogical materials to be implemented in the AWE tool. A sub-corpus (Corpus-72) was compiled with 72 RAs randomly chosen from Corpus-480 for manual and automated analyses. Next, to seek the best descriptive framework for the structure of engineering RA abstracts, two move schemata were compared: (1) IMRD (Introduction, Methodology, Results, and Discussion) and (2) CARS (Create-A-Research-Space, Swales, 1990). Abstracts in Corpus-72 were annotated and these two schemas were evaluated according to three quantitative metrics devised specifically for this comparison. Applying a statistical natural language processing (StatNLP) approach, a Support Vector Machine (SVM) was trained for automated move classification in abstracts. Formulaic language in engineering RA sections was used as linguistic features to automatically classify moves in abstracts. Additionally, four-word lexical bundles and verb categories were identified from Corpus-480 and Corpus-72, respectively. Four-word lexical bundles associated with moves in abstracts were extracted automatically. Additionally, verb categories (i.e., tense, aspect, and voice) in moves of abstracts were identified using CyWrite::Analyzer, a hybrid (statistical and rule-based) NLP software. Finally, the AWE tool was developed, based on the findings from the previous iterations, and implemented in an English-as-a-foreign-language (EFL) classroom setting. Through analyzing students’ drafts before and after using the tool, and responses to a questionnaire and a semi-structured interview, the AWE tool was evaluated based on Chapelle’s (2001) CALL evaluation framework. The findings showed that students attempted to improve their abstracts by adding, deleting, or changing the sequences of their sentences, lexical bundles, and verb categories in their abstracts. Their attitudes toward the effectiveness and appropriateness of the tool were quite positive. Overall, the AWE tool drew students’ attention to the use of lexical bundles and verb categories to achieve the communicative purposes of each move in their abstracts. In conclusion, this dissertation started from Taiwanese engineering students’ needs to improve their English abstract writing, and attempted to develop and evaluate an AWE tool for assisting them. Following DBR, the findings from this dissertation are discussed to improve the next generation of the AWE tools. Having these iterations in place, future studies can focus on developing pedagogical materials from genre-based analysis in different disciplines to fulfill learners’ needs
