Recently, broadcast news speech recognition has become one of the most attractive research areas. If we can transcribe automatically the broadcast news and store their contents in the text form instead of the video or audio signal itself, it will be much easier for us to search for the multimedia databases to obtain what we need. However, the desirable speech signal in the broadcast news are usually affected by the interfering signals such as the background noise and/or the music. Also, the speech of the reporter who is speaking over the telephone or with the ill-conditioned microphone is severely distorted by the channel effect. The interfered or distorted speech may be the main reason for the poor performance in the broadcast news speech recognition. In this paper, we investigated some methods to cope with the problems and we could see some performance improvements in the noisy broadcast news speech recognition.

The past, present, and future of online journalism in Korea are inextricably bound up with the portal site news services. In traditional journalism, finite news media took hold on news consumption completely because of performing news production and distribution simultaneously. Since then, in the age of multi-media and multi-channel, the audience selection has become more important because of greatly increasing news media and then exploding news production. In online journalism, the news distribution have emerged as the most important field because of the intensive consuming the portal site news services making use of various news easier, the characteristic of news consumption focusing on not news media brands but news media contents, etc. Therefore, the news present landscape of Korean journalism oriented news distribution has been completed by that the portal site news services became the symbol of online journalism. That the portal site news services performing only news distribution have more influence than the paper based online newspapers and Internet based online newspapers producing news means the change of media power. By this, a conflict between news media and portal site news services appears at all times.

Recently in Korea, YouTube stock channels increased rapidly due to the high social interest in the stock market during the COVID-19 period. Accordingly, the role of new media channels such as YouTube is attracting attention in the process of generating and disseminating market information. Nevertheless, prior studies on the market forecasting power of YouTube stock channels remain insignificant. In this study, the market forecasting power of the information from the YouTube stock channel was examined and compared with traditional news media. To measure information from each YouTube stock channel and news media, positive and negative opinions were extracted. As a result of the analysis, opinion in channels operated by media outlets were found to be leading indicators of KOSPI market returns among YouTube stock channels. The prediction accuracy by using logistic regression model show 74%. On the other hand, Sampro TV, a popular YouTube stock channel, and the traditional news media simply reported the market situation of the day or instead showed a tendency to lag behind the market. This study is differentiated from previous studies in that it verified the market predictive power of the information provided by the YouTube stock channel, which has recently shown a growing trend in Korea. In the future, the results of advanced analysis can be confirmed by expanding the research results for individual stocks.

Recently, media diplomacy takes on a substantial role in information war not only in setting global agenda but also in delivering their favored views and frames. Focusing on its crucial impact, this study attempts to investigate empirically the relationship between national prestigious media's news coverage and it's own foreign policy particularly about the 2011 Libya conflict. The total of 530 news articles in such 24 hour English news channels as BBC World, Cnn International, Russia Today, France24, Al Jazeera English and Deusche Welle were analyzed for this study. The analyses reveal that Libya coverages of those news channels are entirely constructed in the context of the foreign policy. To put it concretely, there was the undeniable level of differences in terms of quoting relevant sources, viewpoints, attitudes and frames for the pursuit of media diplomacy helped by high quality journalism. The authors argue in this regard that protecting information sovereignty should be urgently discussed even in the time of digital revolution. To launch 24-hour English news channel like 'Korea 24' would be a possible strategy for influencing global agenda and perspective in way of supporting national interests.

This research verified the effects of anchors' reputation and brand equity evaluation of news on the continuous watching intention for general news channels such as KBS, JTBC, and YTN. Data collection was conducted on nationwide 539 adults who were watching news for each channel, and Hierarchical regression analysis was conducted to analyze the impact of the anchors' reputation and news brand equity evaluation factors. As a result, first, KBS showed continuous watching intention as viewers are men, their academic background is lower, they are more conservative, viewing frequency is higher, anchor awareness is higher, and news awareness and news preference are higher. Second, JTBC showed continuous watching intention as viewers are more advancing, viewing frequency is higher, anchor confidence, news awareness, and news preference, and evaluation on news quality are higher. Third, YTN showed continuous watching intention as their viewing frequency is higher, anchor confidence and anchor attraction are higher, news preference and evaluation on news quality are higher.

This paper examined how the millennial generation consumes mobile news through social networking sites with regards to user patterns, preference topics and news values, and whether news topics and news values may influence their overall mobile SNS news consumption and interactivity. The findings show that more than 2/3 of respondents consumed mobile SNS news at least once everyday for 30minutes to one-hour. Male millennials tended to use Facebook and Kakao-talk more than female. While the portal site was the most accessed channel for consuming mobile news, SNS was the second, more than the combined use of national daily papers, TV, and internet newspapers. The respondents' demographic characteristics and news topics also affect the form and degree of news interactivity. With regards to their preferences and prioritization of news values, millennials tend to perceive 'impact' and 'usefulness' as being most important, despite the differences of their demographic characteristics. They also preferred those news values most. There were significant differences in terms of preferred news topics according to the demographics' characteristics.

This research aims to analyze the characteristics of the channel brand components, identities in accordance with the organizational strategies of the programmes, and brand structures of the comprehensive programming channels. The channels promote themselves mobilizing a variety of channel brand components and, ecxept Channel A, JTBC, TV Chosun, and MBN coined its names which are reminiscent of their parents corporations. The organizational strategies of the programmes are related with the channel identities. TV Chosun, for instance, branded themselves as 'conservative advocate' while focusing on news programs, and Channel A also takes conservative bias strategy focusing on the news programmes, especially after the 2012 presidential election. JTBC, however, organizes drama and entertainment programmes intensively being equivalent to that of terrestrial broadcasting programmes, and MBN positioned neutral and center with the news and cultural programmes. Referring to the brand architecture, which reveals the structural system of the brand, it is argued that TV Chosun and MBN take the integrated corporate brand strategy, while JTBC tries to mix and balance the brands of the parent corporation and its own independent one. Channel A, exceptionally, doesn't take a name of its parent corporation 'Dong-A'. In conclusion, it is argued that the comprehensive programming channels utilize and take the parent corporate brand, mixed brand, and independent brand in accordance with the brand power and circumstances of their own parent corporates.

Broadcast news transcription is one of the hardest tasks in speech recognition because broadcast speech signals have much variability in speech quality, channel and background conditions. We developed a Korean broadcast news speech recognizer. We used a morpheme-based dictionary and a language model to reduce the out-of·vocabulary (OOV) rate. We concatenated the original morpheme pairs of short length or high frequency in order to reduce insertion and deletion errors due to short morphemes. We used a lexicon with multiple pronunciations to reflect inter-morpheme pronunciation variations without severe modification of the search tree. By using the merged morpheme as recognition units, we achieved the OOV rate of 1.7% comparable to European languages with 64k vocabulary. We implemented a hidden Markov model-based recognizer with vocal tract length normalization and online speaker adaptation by maximum likelihood linear regression. Experimental results showed that the recognizer yielded 21.8% morpheme error rate for anchor speech and 31.6% for mostly noisy reporter speech.

This study aims to examine the characteristics of news content and users' reactions in local broadcasting Youtube news' channel, and explore how the local media should response in the new online video environment. YouTube Open API sampled 3,950 news-related videos uploaded over a month on 31 YouTube news channels nationwide. The content analysis was performed on the basis of the analysis of individual videos, such as characteristics of each content and users' reactions. As a result, a few news channels have produced digital-only content, but the ratio has been very low, most were broadcast replay videos with titles and formats uploaded as they were. In some cases, it still operates as a comprehensive channel, which failed to show its expertise as an independent digital news platform. This shows that theses YouTube channels lacks differentiation from TV or its own web page, and is still skewed to the auxiliary role or online archive function of TV platform. Nevertheless, digital-only content, which can be a national issue based on regional expertise, has led to a higher number of views and users reactions, suggesting that is a realistic and effective strategy with expandability in online space in the future.
