A system for popular Thai slang extraction from social media content with n-gram based tokenization

With increased penetration of smart devices and internet connectivity, many Thais are more readily engaged in social media, online forums, and chat groups. As there is an increased consumption of social media content, there is a shift from the consumption of traditional medias in which formal language are used regularly such as broadcast and traditional print medias. Social media posts are a reflection of the trend, where posts usually made by younger generations usually involve communication in slang and non-formal language which is not typically available in formalized dictionaries. As the Thai population like to follow trends, one of behaviors of that many Thai social media users engage in, is to follow the latest popular social media trends in slang and word usage. As slang are changed and evolved over time, it is usually useful to have an online mining tool in which could capture the trends of emerging and popular slang. This paper proposes an approach that extracts popular Thai slang by comparing social media posts and utilizing tokenization, a dictionary based approach to extract unknown words, before expanding it by using n-gram approach to figure what are currently trending and popular slang words.

Extending a Standard Tablet into a Gaming Platform with Projected Parallax Layers

Computer games are considered an important entertainment medium. In addition to engaging gameplay, there are many other factors that attract the audiences to the games. The visual presentation is considered as an important factor and many technologies such as virtual reality (VR), stereoscopy, and autostereoscopy are some of the approaches that are used to enhance the visual presentation of games by providing 3D depth that is not available in typical 2D raster displays. Though stereoscopy and autostereoscopy approaches have been used in commercial VR and 3D display products, one of the huge drawback of using the devices is that many users, especially in the older demographics, reported vertigo, nausea, and cyber-sickness during the usage of the devices. To counter those issues, it is possible to refine the stereoscopy/autostereoscopy technology, or use alternative approaches that can provide the perception of 3D and depth to the visual presentation with less strain on the eyes which is the focus of this research. An implementation of a visual projection approach using a clip-on hardware extension on standard tablets to create a gaming platform that can display physical parallax effects for enhanced depth. In addition to developing the clip-on hardware, a number of games were developed on the platform, and a number of techniques on developing content on the platform are described.

An IoT Implementation for Vacancy State of Public Coin Operated Washing Machine Using Vibration Level Sensors in an Apartment Setting in Thailand

Public coin operated washing machines are common in many apartment complexes in Thailand. As many tenants are from lower socioeconomic standing, many tenants do not own a washing machine. Due to that, public coin operated washing machines serve as an affordable solution for tenants when doing their laundry. However, in many apartments, the number of public coin operated washing machines are usually inadequate compared with the number of tenants, which can lead to long queues. This research aims to help alleviate the issue, by utilizing an IoT solution using vibration level sensors to provide tenants the ability to be able to know if the public washing machines are vacant. The IoT solution proposed can be easily installed in many apartment complexes using the existing WiFi network infrastructure that is available in many apartment complexes.

Extending the Socio-Economic Status (SES) Prediction System Based on the Thailand Marketing Research Society (TMRS) Standardized SES Classification for Thai Upcountry Urban Subjects

This research proposes an extension to the prediction system of socio-economic status (SES) by using asset ownership data, that the authors proposed previously on subjects based in Bangkok, to include Thai upcountry urban subjects. The prediction system is based on the standardized SES classification that is proposed by the Thailand Marketing Research Society (TMRS) and widely adopted by marketing research firms in Thailand. The paper describes the TMRS SES classification briefly, proposes a prediction system for Thai upcountry urban subjects based on asset ownership data, and evaluate the performance of the predictor. A mobile application was created for the prediction system.

Potential Z-Fighting Conflict Detection System in 3D Level Design Tools

Z-Fighting is an effect that happens in 3D scenes when two co-planar surfaces share similar values in the z-buffer which leads to flicking and visual artifacts during the rendering process due to conflicting order of rendering the surface. However in 3D level design, scenes created by the tools can be complex, in which level designers can inadvertently place co-planar surfaces that would be susceptible to z-fighting. Level designers typically notice the z-fighting artifact through visual inspection through the usage of a 3D walkthrough test on the scene which is time-consuming and easy to miss. To solve the issue, a proposal of a z- fighting detection system for level design tools is proposed to streamline the process of detecting potential hotspots where z-fighting conflicts may occur from co-planar objects.

Optimizing Player Throughput for Interactive Motion Based Kiosk Games – A Case Study from the PTT Technobots Campaign

Maintaining booths that are attractive to exhibition attendees is one of the main goals of exhibitors. One of the popular tactics to attract attention is to utilize new and emerging technology to create fresh new types of interactive booths, in which motion-based kiosk games are gaining popularity in this domain. However motion-based kiosk games are usually designed using conventional computer game design principles and are not optimized for exhibitions which results in a low player throughput. This paper examines the issues behind conventional game design principles, and proposes changes that would improve player throughput and is empirically validated upon a real world case study in which the author has worked on. The case study selected is the Petroleum Authority of Thailand (PTT) Technobots Campaign, in which a series of motion-based kiosk games were deployed at a number of popular department stores in Bangkok, Thailand during the period of May-Aug 2013.
