1. 特邀大会报告题目：Mosaics in Big Data：Stratosphere, Apache Flink, and Beyond

特邀大会报告摘要: The global database research community has greatly impacted the functionality and performance of data storage and processing systems along the dimensions that define “big data”, i.e., volume, velocity, variety, and veracity. Locally, over the past five years, we have also been working on varying fronts. Among our contributions are: (1) establishing a vision for a database-inspired big data analytics system, which unifies the best of database and distributed systems technologies, and augments it with concepts drawn from compilers (e.g., iterations) and data stream processing, as well as (2) forming a community of researchers and institutions to create the Stratosphere platform to realize our vision. One major result from these activities was Apache Flink, an open-source big data analytics platform and its thriving global community of developers and production users. Although much progress has been made, when looking at the overall big data stack, a major challenge for database research community still remains. That is, how to maintain the ease-of-use despite the increasing heterogeneity and complexity of data analytics, involving specialized engines for various aspects of an end-to-end data analytics pipeline, including, among others, graph-based, linear algebra-based, and relational-based algorithms, and the underlying, increasingly heterogeneous hardware and computing infrastructure. At TU Berlin, DFKI, and the Berlin Big Data Center (BBDC), we aim to advance research in this field via the Mosaics project. Our goal is to remedy some of the heterogeneity challenges that hamper developer productivity and limit the use of data science technologies to just the privileged few, who are coveted experts.

2. 特邀大会报告题目：Medical Treatment Support by Data Engineering Technologies

特邀大会报告摘要: Our daily lives have been greatly impacted by information technology which has become one of the most important infrastructure. As an example, the information technology has introduced significant changes in the medical field, such as medical image recognition, medical sensor data processing, computational drug design, and electronic medical record (EMR) systems. Focusing on the EMR systems, the data engineering technologies has high potentials for supporting them. The EMR systems do not only reduce the cost of managing medical treatment histories, but also can improve medical processes by the secondary use of these records. To expedite the secondary use, Japanese government has started a project to collect the EMR from a large number of hospitals in Japan. The clinical pathway service is a good instance of the secondary use of the EMR. Medical workers including doctors, nurses, and technicians generally use clinical pathways as their guidelines for typical sequences of medical treatments. The clinical pathways have been traditionally created by the medical workers themselves based on their experiences with great effort. The candidates of the clinical pathways can be extracted by applying the sequential pattern mining techniques to medical orders in the EMR. It is helpful for the medical workers to verify the correctness of existing clinical pathways or modify them by comparing the extracted frequent sequential patterns. To provide proper patterns as the useful information to the medical workers, there are a number of technical issues to be considered. At first, consideration on time intervals between the medical treatments is essential. Moreover, there are a number of branches in the frequent sequential patterns extracted from the EMR. Visualization of these branches is important to choose appropriate patterns. The issues of cost, safety, and reasoning related to these branches should also be considered.

3. 特邀大会报告题目：Data Analytics as a Service for Data Scientists

特邀大会报告摘要: Data scientists and domain experts often face challenges when dealing with large amounts of data, especially due to the scale and limited IT knowledge and infrastructure maintenance skills. In this talk, I will present several software solutions we are developing to support data analytics as a service to these users. These solutions include Apache AsterixDB as an open source parallel database, Cloudberry as a middleware system to support data visualization, and Texera as a system to enable browser-based text analytics using declarative workflows. These solutions can be integrated to support data ingestion, storage, indexing, querying, visualization, and analytics.. As an example, we will report experiences of using these solutions to support management of large-scale social media data (e.g., billions of tweets in terabytes) as a service to researchers of various disciplines such as social science and public health from several schools and universities.

4.特邀大会报告题目： Building Scalable Machine Learning Solutions for Data Curation

特邀大会报告摘要:Machine learning tools promise to help solve data curation problems. While the principles are well understood, the engineering details in configuring and deploying ML techniques are the biggest hurdle. In this talk I discuss why leveraging data semantics and domain-specific knowledge is key in delivering the optimizations necessary for truly scalable ML curation solutions. The talk focuses on two main problems: (1) entity consolidation, which is arguably the most difficult data curation challenge because it is notoriously complex and hard to scale; and (2) using probabilistic inference to suggest data repair for identified errors and anomalies using our new system called HoloCLean. Both problems have been challenging researchers and practitioners for decades due to the fundamentally combinatorial explosion in the space of solutions and the lack of ground truth. There’s a large body of work on this problem by both academia and industry. Techniques have included human curation, rules-based systems, and automatic discovery of clusters using predefined thresholds on record similarity Unfortunately, none of these techniques alone has been able to provide sufficient accuracy and scalability. The talk aims at providing deeper insight into the entity consolidation and data repair problems and discusses how machine learning, human expertise, and problem semantics collectively can deliver a scalable, high-accuracy solution.
