Abstract

Purpose

The purpose of this paper is to propose an automatic method to generate semantic annotations of football transfer in the news. The current automatic news integration systems on the Web are constantly faced with the challenge of diversity, heterogeneity of sources. The approaches for information representation and storage based on syntax have some certain limitations in news searching, sorting, organizing and linking it appropriately. The models of semantic representation are promising to be the key to solving these problems.

Design/methodology/approach

The approach of the author leverages Semantic Web technologies to improve the performance of detection of hidden annotations in the news. The paper proposes an automatic method to generate semantic annotations based on named entity recognition and rule-based information extraction. The authors have built a domain ontology and knowledge base integrated with the knowledge and information management (KIM) platform to implement the former task (named entity recognition). The semantic extraction rules are constructed based on defined language models and the developed ontology.

Findings

The proposed method is implemented as a part of the sport news semantic annotations-generating prototype BKAnnotation. This component is a part of the sport integration system based on Web Semantics BKSport. The semantic annotations generated are used for improving features of news searching – sorting – association. The experiments on the news data from SkySport (2014) channel showed positive results. The precisions achieved in both cases, with and without integration of the pronoun recognition method, are both over 80 per cent. In particular, the latter helps increase the recall value to around 10 per cent.

Originality/value

This is one of the initial proposals in automatic creation of semantic data about news, football news in particular and sport news in general. The combination of ontology, knowledge base and patterns of language model allows detection of not only entities with corresponding types but also semantic triples. At the same time, the authors propose a pronoun recognition method using extraction rules to improve the relation recognition process.

Abstract

Purpose

The growth of online data and services on the Web have have led to the Web become an indispensable tool for the tourist industry. It is not denied that various approaches bring benefits for visitors, in supporting their searching for tourist attractions, such as interesting places for the visit, eating or staying. However, like a coin has two sides, too much information would present a difficulty for people when planning their journeys. Generally, tourists usually have problems when trying to find satisfactory accommodation if references to nearby restaurants, sights or event locations are lacking. In addition, travelers suffer from the information overload when they look for information about potential destinations, events and related services. Providing relevant and up‐to‐date information for the tourists with different personal interests is still a challenging task for the tourist guide information systems. The purpose of this paper is to propose a semantic approach for searching tourist information and generating travel itinerary.

Design/methodology/approach

The paper focus on introducing an ontological model for representation of tourist resources as well as traveler's profile. Based on this model, smart user interfaces facilitating the semantic search have been implemented in the mobile travel guide application. In addition, the authors propose an algorithm for generating travel itinerary which combines semantic matching with ant colony optimization technique.

Findings

The Semantic Tourist informAtion Access and Recommending (STAAR) system, which has been implemented to promote the travel activity in Hanoi, reveals the advantages of the semantic approach in the development of smart application with ontology‐based, user‐friendly interface and high precision information search features. An experiment was conducted to show that the proposed algorithm generates travel itinerary relevant to both criteria of itinerary length and user interest.

Originality/value

This paper presents a novel algorithm for planning a travel itinerary that is optimized on the length as well as semantically matching the user interests.

Abstract

Purpose

The purpose of this paper is to quantitatively evaluate which of the elements of five management practice constructs – management commitment, quality practice, team-based work, training, and sharing and understanding – can significantly lessen the adverse impact of cultural differences on efficient technology transfer.

Design/methodology/approach

Exploratory factor analysis, confirmatory factor analysis, and structural equation modeling multigroup analysis are used to analyze structured survey data from 223 Japanese manufacturing subsidiaries in Vietnam.

Findings

The following are the primary factors that moderate the adverse impact of cultural difference on efficient technology transfer: employees’ understanding of quality; top managements’ communication of clear goals and procedures for technology transfer; the nature of the collaborative teamwork and frequent communication about technical issues among Japanese experts and Vietnamese staff; sending of key Vietnamese technical staff to Japan for technological seminars and on-the-job training while providing them with the appropriate materials and guidelines.

Practical implications

Although cultural diversity’s impact on technology transfer may never be problem-free, Japanese and Vietnamese managers should be aware of the effects of differing cultural values and use the appropriate interfaces to minimize cultural problems, maintain a cooperative environment, and transform cultural values into business value.

Originality/value

Cross-cultural technology transfer research, from the knowledge-based perspective, has produced interesting findings but has not yet identified which managerial elements effectively reduce the adverse impact of cultural difference on efficient technology transfer. This study addresses that shortcoming through the organizational learning perspective.

Abstract

Purpose

The purpose of this paper is to incorporate risk in technical efficiency of ASEAN banks in a panel data framework for the period 2000 to 2015.

Design/methodology/approach

The directional distance function and semi-parametric framework are employed to estimate efficiency scores for two scenarios, one with only good outputs and the other with a combination of good and bad outputs.

Findings

The findings show there is no evidence of technological progress for banks in ASEAN and concerns about the outperformance of Vietnam’s banks. In addition, performance of Vietnam’s banks tends to be distorted by low level of loan loss reserves.

Practical implications

To reflect the true performance and shorten the period of removing bad assets, the State Bank of Vietnam can request banks in Vietnam to book more loan loss reserves.

Originality/value

By examining such a new approach, this study makes an early attempt to incorporate credit risk into the banking efficiency in ASEAN region.
