To select suitable knowledge graphs for use from many knowledge graphs, quality assessment is particularly important. As an important thing of quality assessment, completeness assessment generally refers to the ratio of the current data volume to the total data volume.When evaluating the completeness of a knowledge graph, it is often necessary to refine the completeness dimension by setting different completeness metrics to produce more complete and understandable evaluation results for the knowledge graph.However, lack of awareness of requirements is the most problematic quality issue. In the actual evaluation process, the existing completeness metrics need to consider the actual application. Therefore, to accurately recommend suitable knowledge graphs to many users, it is particularly important to develop relevant measurement metrics and formulate measurement schemes for completeness. In this paper, we will first clarify the concept of completeness, establish each metric of completeness, and finally design a measurement proposal for the completeness of knowledge graphs.展开更多

Many process discovery approaches were invented in the past twenty years;however, most of them have difficulties in handling multi-instance sub-processes. To address this challenge, we first introduce a multi-instance business process model(MBPM) to support the modeling of processes with multiple sub-process instantiations. Formal semantics of MBPMs are precisely defined by using multi-instance Petri nets(MPNs)that are an extension of Petri nets with distinguishable tokens.Then, a novel process discovery technique is developed to support the discovery of MBPMs from event logs with sub-process multi-instantiation information. In addition, we propose to measure the quality of the discovered MBPMs against the input event logs by transforming an MBPM to a classical Petri net such that existing quality metrics, e.g., fitness and precision, can be used.The proposed discovery approach is properly implemented as plugins in the Pro M toolkit. Based on a cloud resource management case study, we compare our approach with the state-of-theart process discovery techniques. The results demonstrate that our approach outperforms existing approaches to discover process models with multi-instance sub-processes.展开更多

In this study, the development course, concept, objectives and design elements of complete streets were studied, and the conceptual framework of street integrity evaluation was established. Shashen Road in Shenzhen City was as a case to analyze the problems existing in traditional street design and explore the spatial design method of complete streets. It is pointed out that street design should adapt to local conditions and be optimized according to current situation. The improvement measures that can be implemented were proposed to enhance the vitality of streets.展开更多

Organizations depend on the information?they store and they are required to have appropriate mechanisms to support the functional needs of information storage, management and retrieval. Currently, there are several tools in the market, both free software and proprietary license, normally named Enterprise Content Management (ECM) tools, which offer relevant solutions in this context. This paper presents a comparative study among several of the most commonly used ECM tools. It starts with a systematic review of the literature to analyze possible solutions and then it defines a characterization schema instantiated in a particular case, the Regional Government of Andalusia.展开更多
