i-JEN: Visual interactive Malaysia crime news retrieval system
Supporting crime news investigation involves a mechanism to help monitor the current and past status of criminal events. We believe this could be well facilitated by focusing on the user interfaces and the event crime model aspects. In this paper we discuss on a development of Visual Interactive Malaysia Crime News Retrieval System (i-JEN) and describe the approach, user studies and planned, the system architecture and future plan. Our main objectives are to construct crime-based event; investigate the use of crime-based event in improving the classification and clustering; develop an interactive crime news retrieval system; visualize crime news in an effective and interactive way; integrate them into a usable and robust system and evaluate the usability and system performance. The system will serve as a news monitoring system which aims to automatically organize, retrieve and present the crime news in such a way as to support an effective monitoring, searching, and browsing for the target users groups of general public, news analysts and policemen or crime investigators. The study will contribute to the better understanding of the crime data consumption in the Malaysian context as well as the developed system with the visualisation features to address crime data and the eventual goal of combating the crimes
Construction and Applications of Billion-Scale Pre-trained Multimodal Business Knowledge Graph
Business Knowledge Graphs (KGs) are important to many enterprises today,
providing factual knowledge and structured data that steer many products and
make them more intelligent. Despite their promising benefits, building business
KG necessitates solving prohibitive issues of deficient structure and multiple
modalities. In this paper, we advance the understanding of the practical
challenges related to building KG in non-trivial real-world systems. We
introduce the process of building an open business knowledge graph (OpenBG)
derived from a well-known enterprise, Alibaba Group. Specifically, we define a
core ontology to cover various abstract products and consumption demands, with
fine-grained taxonomy and multimodal facts in deployed applications. OpenBG is
an open business KG of unprecedented scale: 2.6 billion triples with more than
88 million entities covering over 1 million core classes/concepts and 2,681
types of relations. We release all the open resources (OpenBG benchmarks)
derived from it for the community and report experimental results of KG-centric
tasks. We also run up an online competition based on OpenBG benchmarks, and has
attracted thousands of teams. We further pre-train OpenBG and apply it to many
KG- enhanced downstream tasks in business scenarios, demonstrating the
effectiveness of billion-scale multimodal knowledge for e-commerce. All the
resources with codes have been released at

The Semantic Grid: A future e-Science infrastructure
e-Science offers a promising vision of how computer and communication technology can support and enhance the scientific process. It does this by enabling scientists to generate, analyse, share and discuss their insights, experiments and results in an effective manner. The underlying computer infrastructure that provides these facilities is commonly referred to as the Grid. At this time, there are a number of grid applications being developed and there is a whole raft of computer technologies that provide fragments of the necessary functionality. However there is currently a major gap between these endeavours and the vision of e-Science in which there is a high degree of easy-to-use and seamless automation and in which there are flexible collaborations and computations on a global scale. To bridge this practiceâaspiration divide, this paper presents a research agenda whose aim is to move from the current state of the art in e-Science infrastructure, to the future infrastructure that is needed to support the full richness of the e-Science vision. Here the future e-Science research infrastructure is termed the Semantic Grid (Semantic Grid to Grid is meant to connote a similar relationship to the one that exists between the Semantic Web and the Web). In particular, we present a conceptual architecture for the Semantic Grid. This architecture adopts a service-oriented perspective in which distinct stakeholders in the scientific process, represented as software agents, provide services to one another, under various service level agreements, in various forms of marketplace. We then focus predominantly on the issues concerned with the way that knowledge is acquired and used in such environments since we believe this is the key differentiator between current grid endeavours and those envisioned for the Semantic Grid
Natural Language Generation for Advertising: A Survey
Natural language generation methods have emerged as effective tools to help
advertisers increase the number of online advertisements they produce. This
survey entails a review of the research trends on this topic over the past
decade, from template-based to extractive and abstractive approaches using
neural networks. Additionally, key challenges and directions revealed through
the survey, including metric optimization, faithfulness, diversity,
multimodality, and the development of benchmark datasets, are discussed
Learning to Order Facts for Discourse Planning in Natural Language Generation
This paper presents a machine learning approach to discourse planning in
natural language generation. More specifically, we address the problem of
learning the most natural ordering of facts in discourse plans for a specific
domain. We discuss our methodology and how it was instantiated using two
different machine learning algorithms. A quantitative evaluation performed in
the domain of museum exhibit descriptions indicates that our approach performs
significantly better than manually constructed ordering rules. Being
retrainable, the resulting planners can be ported easily to other similar
domains, without requiring language technology expertise.Comment: 8 pages, 4 figures, 1 tabl
Formative evaluation of a patient-specific clinical knowledge summarization tool
To iteratively design a prototype of a computerized clinical knowledge summarization (CKS) tool aimed at helping clinicians finding answers to their clinical questions; and to conduct a formative assessment of the usability, usefulness, efficiency, and impact of the CKS prototype on physiciansâ perceived decision quality compared with standard search of UpToDate and PubMed
