This paper aims to describe a knowledge-based pronunciation generation system for French. It has been reported that a rule-based pronunciation generation system outperforms most of the data-driven ones for French; however, only a few related studies are available due to existing language barriers. We provide basic information about the French language from the point of view of the relationship between orthography and pronunciation, and then describe our knowledge-based pronunciation generation system, which consists of morphological analysis, Part-of-Speech (POS) tagging, grapheme-to-phoneme generation, and phone-to-phone generation. The evaluation results show that the word error rate of POS tagging, based on a sample of 1,000 sentences, is 10.70% and that of phoneme generation, using 130,883 entries, is 2.70%. This study is expected to contribute to the development and evaluation of speech synthesis or speech recognition systems for French.

In this paper, an electronic control unit of the automobile engine for optimal fuel injection an spark timing control has been designed and developed. This system includes hardware and software for a precise control of fuel injection and ignition timing. Especially, the crank angle sensor provides two separate signals: One is the position signal (POS) which indicates 180 degree pulses per revolution, and the other is the reference signal (REF) that represents each cylinder individually. Consequently, the developed engine control system has been able to control fuel injection and ignition timing more quickly and accurately. Through the experiment, it has been found that the fuel injection duration and the position of MBT have been influenced by coolant temperature, air flow rate and engine speed.

형태소 분석기는 많은 자연어 처리 영역에서 필수적인 언어 도구로 활용되기 때문에 형태소에 대한 품사를 결정하는 것은 매우 중요하다. 최근 음절 기반으로 형태소의 품사를 태깅하는 방법에 대한 연구들이 많이 진행되고 있다. 음절 단위 형태소 분석은 음절 단위로 분리된 형태소에 대해서 기계학습을 이용하여 분리된 음절 단위로 품사를 태깅하는 단계를 가진다. 본 논문에서는 기존의 CRF를 이용한 음절 단위 품사 태깅 방법을 개선하기 위해 bi-LSTM-CRFs를 이용한 방법을 제안한다. 또한, bi-LSTM-CRFs의 입력을 음절의 품사 분포 벡터를 이용해 확장함으로써 음절 단위 품사 태깅의 성능을 향상 시켰다.

Clustering is well known method and that can be used in statistical machine translation. In this paper we propose a corpus clustering method using syntactic structure and POS information of dependency grammar. And using this cluster language model as additional feature to phrased-based statistical machine translation system to improve translation Quality.

This work studies the effects of transient reflectance on the thermal responses of a metal(gold) thin-film during ultrashort laser heating. The heating process is calculated using the conventional conduction model (parabolic one-step: POS), parabolic two-step model (PTS) with and without variable properties, hyperbolic two-step model (HTS). Results from the HTS model are very similar to those from the PTS model, since the laser heating time in this study is greater than the electron relaxation time. PTS model with variable properties, however, results in totally different temperature profiles compared to those from POS models or calculation with constant properties. Transient reflectances are estimated from electron temperature distributions and based on the linear relationship between the electron temperature and complex dielectric constants. Reflectance of the front surface can be changed with respect to dielectric constants, while those of the rear surface remain unchanged.

거래 시 발생하는 잔돈들로 인해 이용자들은 소지의 불편함이 있고 서랍속에서 잠자고 있는 동전들로 인해 연간 수억 원의 동전 발행 비용이 발생하고 있다. 본 시스템은 스마트 기기들을 이용한 사용자들을 대상으로 잔돈을 적립하여 기부하기, 선물하기, 구매하기 등의 시스템을 설계하고 이를 테스트하였다. 본 시스템은 기본적인 잔돈 적립 및 소비 기능 외에 가맹점이 확보되지 않은 상태에서 사용자 앱을 테스트할 수 있도록 설계한 부분과 SNS와 연계되어 커뮤니티를 활용할 수 있다는 것이 특이점이다. 본 시스템을 통해서 이용자들의 편의성과 만족, 동전 발행이라는 사회적 비용 절감, 기부문화의 확산 등을 기대하고 있다.

The prepositional object (PO) of an active sentence in English can sometimes be passivized, becoming the subject of the corresponding passive sentence. In particular, the verb (V) and preposition (P) in the English prepositional passive (P-Passive) are assumed to be reanalyzed to form a single structural unit, giving the status of a verbal object to the PO to be passivized. However, not every V+P sequence can undergo reanalysis, permitting the passivization of POs. Thus, we have to explain what licenses the reanalysis of V and p. resulting in an acceptable P-Passive sentence. In this paper, I will identify the factors which determine the passivization possibilities of POs and explain how they interact with one another. The results of this study will illustrate how formal and functional factors work together to form a major syntactic construction and to determine its grammaticality and acceptability.

It is argued in this paper that, in determining semantic similarity, Korean words should be recategorized with a focus on the semantic relation to ontology in light of cross-linguistic morphological variations. It is proposed, in particular, that Korean semantic similarity should be measured on three tracks, human judgements track, relatedness track, and cross-part-of-speech relations track. As demonstrated in Yang et al. (2015), GloVe, the unsupervised learning machine on semantic similarity, is applicable to Korean with its performance being compared with human judgement results. Based on this compatability, it was further thought that the model's performance might most likely vary with different kinds of specific relations in different languages. An attempt was made to analyze them in terms of two major Korean-specific categories involved in their lexical and cross-POS-relations. It is concluded that languages must be analyzed by varying methods so that semantic components across languages may allow varying semantic distance in the vector space models.
