近年来，随着机器语义理解需求的日益增长，知识图谱，即各类实体、概念及其之间的语义关系，日益成为大数据时代知识表示的主要形态之一。知识图谱为语义理解提供了丰富的背景知识，是实现下一代智能信息处理与机器智脑的关键核心基础技术。知识图谱已经在智慧搜索、文本理解等领域发挥巨大价值。 近期伴随着数据处理能力以及机器学习能力的进一步提高，以及知识图谱应用的进一步深化，知识图谱技术面临全新机遇。 同时，知识图谱的海量规模、异构来源、多模形态和复杂结构等特性也对知识图谱技术的发展提出了全新的挑战。
? In recent years, we have witnessed the prosperity of a variety of knowledge graphs (KG) that contain various entities, concepts as well as the semantic relationships among them. The ever-increasing demand for semantic understanding of data drove the continuous research progress about KGs. KGs now have become one of the prominent representations of knowledge in big data era. KGs provide rich background knowledge for semantic understanding and consequently become the underlying technique in the next generation intelligent information processing and building smart machine brain. KGs have been successfully used in many real applications such as smart search and text understanding. Recently, with the enhanced ability of machines to learn from data and manage big data, many new opportunities to use KGs are emerging.?Meanwhile, the research of KG also faces new challenges such as the web-scale, complicated structure, heterogeneous modeling of KGs.
In this workshop, we will invite more than 10 leading researchers around the world to give talks. This workshop aims to introduce the current progress of knowledge graph in both academia and industry, discuss the major research challenges, and design a future plan for knowledge graph research. We welcome all researchers and students to attend the workshop.

The deep learning tsunami continues to take over NLP. In many cases, by replacing hand-crafted and heavily engineered traditional NLP methods, it reduces development cost and achieves performance gain.

Many large-scale machine-readable entity knowledge bases have emerged in recent years and have been shown very useful in building semantic search and deep Q/A systems. As an important tool to enrich the knowledge bases, entity linking can link entity mentions appearing in the Web text with their corresponding mapping entities in a knowledge base and has many applications in the fields of content analysis and business intelligence beyond knowledge base population. However, this task is challenging due to name variations and entity ambiguity. In this talk, we will introduce some of our efforts on entity linking for heterogeneous data, including entity linking for unstructured Web free text, entity linking for structured Web lists and Web tables, and entity linking for tweets, and discuss its various applications too.

Verbs play an important role in the understanding of natural language text. This paper studies the problem of abstracting the subject and object arguments of a verb into a set of noun concepts, known as the “argument concepts”. This set of concepts, whose size is parameterized, represents the fine-grained semantic of a verb. For example, the object of “enjoy” can be abstracted into time, hobby and event, etc. We present a novel framework to automatically infer human readable and machine computable action concepts with high accuracy.

We propose techniques for processing SPARQL queries over a large RDF graph in a distributed environment. We adopt a “partial evaluation and assembly” framework. Answering a SPARQL query Q is equivalent to finding subgraph matches of the query graph Q over RDF graph G. Based on properties of subgraph matching over a distributed graph, we introduce local partial match as partial answers in each fragment of RDF graph G. For assembly, we propose two methods: centralized and distributed assembly. We analyze our algorithms from both theoretically and experimentally. Extensive experiments over both real and benchmark RDF repositories of billions of triples in a cluster of 10-50 machines confirm that our method is superior to the state-of-the-art methods in both the system’s performance and scalability

The acquisition of knowledge becomes scalable. The machine-readable knowledge keeps its pace with the phenomenal “Big Data” era. On the one hand, we have a revolutionary way of piling up knowledge; on the other hand, the technology of making the knowledge graph accessible, i.e. how to serve the knowledge to support real-life applications, evolves slowly. Due to the great connectedness, knowledge data by its very nature is a complex entity graph with rich schemata. This talk presents our efforts of serving real-world knowledge graphs for real-time query processing at scale.

Integrating, representing, and reasoning over human knowledge is a computational grand challenge for the 21st century. Currently, most IR approaches are keyword-based statistical approaches. When the input is sparse, noisy, and ambiguous, knowledge is needed to fill the gap. In this talk, I will focus on knowledge powered short text understanding. I will introduce the Probase project at Microsoft Research, whose goal is to enable machines to understand human communications. Probase is a universal, probabilistic semantic network. It contains millions of concepts, harnessed automatically from a corpus of billions of web pages. It enables probabilistic interpretations of search queries, document titles, ad keywords, etc. The probabilistic nature also enables it to incorporate heterogeneous information naturally. I will introduce the core technique called Conceptualization we develop on this probabilistic semantic network. The goal of conceptualization is to infer concepts in the text. I will show how we leverage conceptualization to improve current web search, ads matching, query recommendation, etc.?

Large-scale knowledge graphs (KGs) contain rich entities and abundant relationships among the entities. Data exploration over KGs allow users to browse the attributes of entities as well as the relations among entities. It therefore provides a good way of learning the structure and coverage of KGs. In this talk, we introduce a system called SEED that is designed to support entity-oriented exploration in large-scale KGs, based on retrieving similar entities of some seed entities as well as their semantic relations that show how entities are similar to each other. A by-product of entity exploration in SEED is to facilitate discovering the deficiency of KGs, so that the detected bugs can be easily fixed by users as they exploring the KGs.
