Integrating character networks for extracting narratives from multimodal data

This study aims to integrate diverse data within narrative multimedia (i.e., artworks containing stories and distributed through multimedia) into a unified character network (i.e., a social network between characters that appear in the story). By combining multiple data sources (e.g., the text, video, and audio), we attempted to enhance the accuracy and semantic richness of existing character networks that confine themselves to a particular data source. To merge various data, we propose story synchronization for (i) improving the accuracy of data extracted from the narrative multimedia and (ii) integrating the data into the unified character network. The story synchronization mainly consists of three steps: synchronizing (i) scenes, (ii) characters, and (iii) character networks. First, we synchronize dialogues in the text and audio, to discover speakers and time of dialogues. This enables us to segment the scene using time periods when dialogues (in the text and audio) and characters (in the video) do not commonly occur. Through the scene segmentation, we can discretize stories in the narrative work. By comparing the occurrence of dialogues and characters in each scene, we synchronize identities of the characters in the text and video (e.g., names and faces of characters). Thereby, we can more accurately estimate participants and time of a conversation between characters (i.e., a set of connected dialogues). Based on the conversation, the existing character networks are refined and integrated into the unified character network. In addition, we verified the efficacy of the proposed methods using movies in the real world, which are among the most accessible and popular narrative multimedia.

Virtual files in a distributed environment

Hierarchical naming schemes have been adopted in a number of distributed filestore designs. These schemes usually fall into one of two categories. In the first, there is a single namespace, with a fixed root, spread over all the machines in the distributed system. The user is unaware of any connection between the logical name and the physical location of a file. In the second, the total namespace is composed of some aggregation of the individual namespaces of the filestores of each component system. In this paper, it is argued that the two categories can coexist in a single distributed computer system. A scheme is described for providing highly available files, using replicated copies, within a UNIX United namespace, which is indefinitely extensible. The reliable files are accessed in exactly the same way as normal files.     

An extension of the technology acceptance model in the big data analytics system implementation environment

Research on the adoption of systems for big data analytics has drawn enormous attention in Information Systems research. This study extends big data analytics adoption research by examining the effects of system characteristics on the attitude of managers towards the usage of big data analytics systems. A research model has been proposed in this study based on an extensive review of literature pertaining to the Technology Acceptance Model, with further validation by a survey of 150 big data analytics users. Results of this survey confirm that characteristics of the big data analytics system have significant direct and indirect effects on belief in the benefits of big data analytics systems and perceived usefulness, attitude and adoption. Moreover, there are mediation effects that exist among the system characteristics, benefits of big data analytics systems, perceived usefulness and the attitude towards using big data analytics system. This study expands the existing body of knowledge on the adoption of big data analytics systems, and benefits big data analytics providers and vendors while helping in the formulation of their business models.

Noetica: a tool for semantic data modelling

Noetica is a tool for structuring knowledge about concepts and the relationships between them. It differs from typical information systems in that the knowledge it represents is abstract, highly connected and includes meta-knowledge (knowledge about knowledge). Noetica represents knowledge using a strongly-typed semantic network. By providing a rich type system it is possible to represent conceptual information using formalised structures. A class hierarchy provides a basic classification for all objects. This allows for a consistency of representation that is not often found in “free” semantic networks and gives the ability to easily extend a knowledge model while retaining its semantics. We also provide visualisation and query tools for this data model. Visualisation can be used to explore complete sets of link-classes, show paths while navigating through the database, or visualise the results of queries. Noetica supports goal-directed queries (a series of user-supplied goals that the system attempts to satisfy in sequence) and path-finding queries (where the system find relationships between objects in the database by following links).

国际视角的横向企业兼并的战略性贸易政策溯源的模型分析

战略性的贸易政策可以对企业兼并行为作出解释,对战略性贸易政策变化的预期增加了国家内企业兼并的可能性。但是对于国际兼并来说情况就有所不同,战略性的贸易政策并不能使兼并的利润提高。同一国家中两个企业之间的兼并可以提高国家运用战略性贸易政策的概率。兼并发生的国家所选择的贸易补贴比较高,而无兼并发生的国家所选择的贸易补贴比较低。
