To improve the efficiency of recommendation algorithm, researchers introduce check-in data into point of interest (POI) recommendation to help users find new and interesting place. However, some researches ignore the signification of time factor for POI recommendation in LBSNs. In this paper, we propose a time-based collaborative filtering algorithm according to the similarity between users which combines the global similarity during a long period and local similarity within a short time interval. The experimental results show that the method we proposed can get more accurate recommendation.","PeriodicalId":340536,"journal":{"name":"Int. J. Inf. Technol.

Firstly, the knowledge of log automaton is applied to the low-frequency log to delete infrequent behaviour in the logs; secondly, the processed logs are added into attributes. Then, the condition-dependent value of the communication characteristics of different module networks is compared with the threshold, and the effective infrequent log is retained to optimise the model. Finally, a practical case is applied, which indicates the effectiveness and validation of the proposed method.","PeriodicalId":340536,"journal":{"name":"Int. J. Inf. Technol.

The task reuse and design automation are challenges of workflow management currently. In this paper, an ontology SDWMO is constructed for workflow resources integration and task request release. An algorithm DOMDM is proposed to achieve the conversion of the data from traditional workflow data base to SDWMO ontology. In order to provide workflow templates for designers, we extract statistic-oriented cases from the workflow database. Based on these cases a Bayesian network is established for workflow template recommendation. We have designed OBWD platform to implement the above methods. The experimental data indicates that OBWD is statistically effective and saves a lot of time for workflow designers. Currently, OBWD has been used in space debris mitigation domain for workflow management. Moreover, our methodology can also be applied in many other domains in the future.","PeriodicalId":340536,"journal":{"name":"Int. J. Inf. Technol.

In this paper, a bench-based ABS test principle was proposed, which can provide different surface adhesion coefficient dynamically for four wheels. And the simulation model consists of the vehicle model, wheel model, braking force model, and tyre-road model, was established to verify the principle. The simulation experiments on a variety of simulated road conditions are carried out. And the comparative analysis between the ABS bench detection model and ABS road test model is accomplished. The comparative analysis indicated that the simulation curves of the bench detection method and those from road test model are highly consistent in the changing trend under different braking conditions, which verified the correctness and feasibility of the proposed bench detection scheme.","PeriodicalId":340536,"journal":{"name":"Int.

Conventional HRM practices including training and development, compensation and benefits and performance appraisal also have an essential role.

We chose Morlet wavelet with similarity and symmetry. The proposed algorithm can demodulate random codes on carrier under low SNR without any prior knowledge. Simulation results show that the bit error rate (BER) curve of the existing blind demodulation algorithms of direct sequence spread spectrum is above the theoretical BER curve of the coherent demodulation. Simulation result of new algorithm shows that BER curve of the blind demodulation of the wavelet transform is below the theoretical BER curve of coherent demodulation. The novel blind demodulation algorithm allows to obtain an 8 dB gain in SNR terms compared with that obtained by the theoretical coherent modulation when SNR is 10–4.","PeriodicalId":340536,"journal":{"name":"Int.

Further, the moderating role of IT ambidexterity was examined between NHRM and innovation performance. This study selected Pakistan's largest IT-based semi-government organisation National Database and Registration Authority (NADRA) as a case study. Data were collected from three major cities (Lahore, Gujranwala and Jhelum) of Pakistan. 500 employees of NADRA participated in the survey-based research. The empirical results found the positive relationship between NHRM practices and innovation performance. The moderating influence of IT ambidexterity was also found in this study. Employees with high IT ambidexterity are more involved in innovation performance. Continuous adaption of technology enhances long-term competitive advantage.
