A Computational Approach to Chinese Characters
Antoine Bossard, Ph.D. (Department of Information Science, Kanagawa University, Japan)
Abstract: Because of the huge number of glyphs involved, Chinese character memorization is a very challenging topic, even for native speakers. Several pedagogical methods have been proposed for foreign learners, yet they often end up in a long list of characters rather hard to process. Our approach is different: Chinese characters are considered from a logical point of view, later extended to an algebraic one. To this aim, we have first formally defined the relations possibly existing between any two such characters, for example is radical of and is contained by. Hence, a set of characters induces a network (see Figure, one color per relation type, e.g. green for is radical of). After extending such approach to a character algebra for facilitated character description and manipulation, we have conducted an ontological analysis of Chinese characters, thus producing a character model which allows for various information science applications. For instance, we have described a novel input method editor (IME) for Chinese characters. In this talk, we will review the motivations and overall progression of this research, the challenges encountered, eventually giving an insight on possible future developments and applications.

Building Smart Buildings using the Service-Oriented Things Framework in the WuKong IoT Middleware
Kwei-Jay Lin, Ph.D. (University of California, Irvine)
Abstract: With the advance of sensing, actuation and wearable technology, Internet of Things (IoT) has become the next IT research focus. Many IT companies have started to invest heavily into this area by developing and inventing innovative IoT products. We have developed a flexible IoT platform and middleware, called WuKong, to support the development of new IoT applications. The WuKong middleware supports the flow-based programming (FBP) paradigm for users to define data and control workflows among virtual, conceptual sensing classes. Users can also specify simple execution policies on when, where, and how an FBP should run in a user’s environment. The WuKong middleware can intelligently decide how to deploy an IoT application by mapping an FBP to physical devices in order to meet the functionality requirements. We have designed smart building applications using “evacuation sensors” that can guide people to find safe exit paths when fires are detected in a building. We have also built smart drones designed to detect and lead human from dangerous areas. Algorithms and techniques can be integrated for real time detection of dangerous events and situations. Combined with data analytics, evacuation sensing can make predictions on dangerous areas for people to avoid. In this talk, the issues, techniques and challenges for evacuation sensing will be discussed.

Performance Impact of Data Locality in MapReduce on Hadoop
Juyeon Jo, Ph.D. (Department of Computer Science, University of Nevada Las Vegas, USA)
Abstract: As the foundation for MapReduce processing, Hadoop is one of the fundamental technologies in big data analytics. Hadoop breaks up large data into data blocks, replicates them, and stores them in a distributed storage system. Data blocks can be placed in a machine where the data will be processed (data local), in a machine in the same rack (rack-local), or in a machine in a different rack (off-rack). As the location of a data block gets farther from the processing node, a higher data transfer overhead is incurred. Therefore, the location of a data block can significantly influence the performance of MapReduce processing. The data locality problem has been approached in many ways including, scheduling, data placement, networking, partition/key, and framework. While the majority of the data locality improvement effort is concentrated in the early stages of MapReduce, it is possible to extend it to later stages. These approaches are called Shallow Data Locality (SDL) and Deep Data Locality (DDL) respectively. DDL can be achieved in two ways: pre-arrangement of the data blocks in a way to reduce data movement, and/or micromanipulation of the data within the data blocks. It has been shown that DDL can improve the performance of MapReduce in certain applications. This talk will introduce the concept of Hadoop data locality, its impact on MapReduce performance, and past approaches to improve data locality. The process of DDL, the analytical models and simulation results, and the experimental results with common benchmarking tools will also be presented.
