  • This paper is a study on the recognition of continuous digits for the implementation of a voice dialing system, and proposes an method of speech recognition using syntactic analysis and One-Stage DP. In order to perform the speech recognition, first of all, we make DMS model by section division algorithm and let continuous digits data be recognized through the proposed One-Stage DP method using syntactic analysis. In this study, 7 continuous digits of 21 kinds which is pronounced by 8 male speakers two or three times, are used. The speaker dependent and speaker independent recognition are performed with the above data by way of the conventional One-Stage DP and the proposed One-Stage DP using syntactic analysis under the condition of laboratory environment. From the recognition experiments, it is shown that the proposed method was better than the established method. And, the recognition accuracy of speaker dependence and independence by the proposed One-Stage DP using syntactic analysis was about 91.7% and 89.7%.

  • A protein's subcellular localization is considered an essential part of the description of its associated biomolecular phenomena. As the volume of biomolecular reports has increased, there has been a great deal of research on text mining to detect protein subcellular localization information in documents. It has been argued that linguistic information, especially syntactic information, is useful for identifying the subcellular localizations of proteins of interest. However, previous systems for detecting protein subcellular localization information used only shallow syntactic parsers, and showed poor performance. Thus, there remains a need to use a full syntactic parser and to apply deep linguistic knowledge to the analysis of text for protein subcellular localization information. In addition, we have attempted to use semantic information from the WordNet thesaurus. To improve performance in detecting protein subcellular localization information, this paper proposes a three-step method based on a full syntactic dependency parser and WordNet thesaurus. In the first step, we constructed syntactic dependency paths from each protein to its location candidate, and then converted the syntactic dependency paths into dependency trees. In the second step, we retrieved root information of the syntactic dependency trees. In the final step, we extracted syn-semantic patterns of protein subtrees and location subtrees. From the root and subtree nodes, we extracted syntactic category and syntactic direction as syntactic information, and synset offset of the WordNet thesaurus as semantic information. According to the root information and syn-semantic patterns of subtrees from the training data, we extracted (protein, localization) pairs from the test sentences. Even with no biomolecular knowledge, our method showed reasonable performance in experimental results using Medline abstract data. Our proposed method gave an F-measure of 74.53% for training data and 58.90% for test data, significantly outperforming previous methods, by 12-25%.

  • The longer the input sentences, the worse the syntactic parsing results, Therefore, a long sentence is first divided into several clauses and syntactic analysis for each clause is performed. Finally, all the analysis results art merged into one, In the merging process, it is difficult to determine the dependency among clauses, To handle such syntactic ambiguity among clauses, this paper proposes an SVM-based clause-dependency determination method. We extract various features from clauses, and analyze the effect of each feature on the performance. We also compare the performance of our proposed method with those of previous methods.

  • Shi (2000) claims that topics must be related to a syntactic position in the comment, thus denying the existence of dangling topics in Chinese. Under Shi's analysis, the dangling topic sentences in Chinese are not topic-comment but subject-predicate sentences. However, Shi's arguments are not without problems. In this paper we argue that topics in Chinese can be licensed not only by a syntactic gap but also by a semantic gap/variable without syntactic realization. Under our analysis, all the dangling topics discussed in Shi (2000) are, in fact, not subjects but topics licensed by a semantic gap/variable that can turn the relevant comment into an open predicate, thus licensing dangling topics and deriving well-formed topic-comment constructions. Our analysis fares better than Shi's in not only unifying the licensing mechanism of a topic to an open predicate without considering how the open predicate is derived, but also unifying the treatment of normal and dangling topics in Chinese,

  • The purpose of this paper is to examine how Chinese speakers realize Korean prosodic phrases in the reading of Korean texts. Prosodic phrase, in this study, is defined as basic unit of spoken language which can be perceived as purely separate phonetic unit by both hearer and speaker, and is realized with a coherent intonational configuration. Prosodic phrase plays an important role in both speech production and perception. In the second language acquisition, prosody influences the accuracy and fluency of spoken language. The main purpose of this study is to describe the aspect of syntagmatic operation of prosody that produces prosodic phrases. We have specifically examined the relations between the prosodic phrase's boundary and its syntactic status. Furthermore, we examined internal syntactic structure of each prosodic phrase. And the results of each analysis were compared to the aspects of prosodic phrases' formation produced by native Korean speakers. The results show that Chinese speakers tend to coincide the prosodic phrases with syntactic structure more than native Korean speakers.

  • This paper attempts to provide an alternative analysis involving categorical issues related to English gerunds. Especially, this paper rejects Maulof's approach that creates a new syntactic category gerund by mixing nominal and verbal categories. This paper identifies two syntactic structures in English gerunds: nominal gerunds and verbal gerunds. This distinction is based on syntactic and semantic characteristics of each type and is intended to account for the external distribution and endocentricity of the construction. Treating verbal gerunds syntactically as verbal categories, this paper proposes that English verbal gerunds act like other verbal categories such as infinitives whereas nominal gerunds behaves much like derived nominals. This paper proposes a few lexical rules that can take care of the two types of gerunds. The proposal can be extended to prepositional complements as well as sentential subject positions. This proposal not only resolves the issues involving distributional properties of the gerund construction but also captures syntactic parallelism observable between gerunds and other verbal constructions in English.

  • The majority of research on Automated Writing Evaluation (AWE) programs has focused primarily on Grammarly, whereas QuillBot and its use in English as a Foreign Language (EFL) classrooms remains limitedly explored. This study examined the effectiveness of using QuillBot on the writing quality of college students. A total of 26 participants took pre- and post-writing tests, and four analytical tools were applied to assess their writing quality in terms of syntactic complexity, lexical diversity, lexical richness, and readability. Results of the syntactic complexity analysis across the four indices demonstrates that the syntactic complexity of EFL writing increased significantly, and substantial differences were observed in lexical richness and readability. These results suggest that QuillBot can compensate for the drawbacks of Grammarly and assist EFL writers in improving their overall writing quality.

  • This study investigates the relationship between syntactic complexity and English proficiency for Korean college students, using the recently developed TAASSC(the Tool for the Automatic Analysis of Syntactic Sophistication and Complexity) program. Essays on the ICNALE(International Corpus Network of Asian Learners of English) corpus were employed and phrasal complexity indices and clausal complexity indices, respectively were used to predict English proficiency level for Korean students. Results of stepwise regression analysis showed that indices of phrasal complexity explained 8% of variance in English proficiency, while indices of clausal complexity accounted for approximately 11%. That is, indices of clausal complexity were slightly better predictors of English proficiency than indices of phrasal complexity, which contradicts Biber et at.(2011)'s claim that phrasal complexity is the hallmark of writing development.
