Extract-Transform-Loading (ETL) tools integrate data from source side to target in building data warehouse. However data structure and semantic heterogeneity exits widely in the enterprise information systems. On the purpose of eliminate data heterogeneity so as to construct data warehouse, this paper introduces domain ontology into ETL process of finding the data sources, defining the rules of data...
Current e-learning systems are primarily resource oriented, rather than cognition oriented. To reduce learners' cognitive overload in e-learning, we proposed a novel e-learning system Yotta tackling the problem of knowledge acquisition, knowledge presentation, and knowledge resources management. The granularity for knowledge acquisition in Yotta is based on knowledge units that are the smallest integral...
Internet Data Centers (IDC) emerge as a major network service platform to converge Internet related services and applications to one location, managing servers, networks, together with valuable and sensitive data of many enterprises. Therefore, an appropriate security approach is essential. Intrusion Detection Systems (IDS) are often deployed in IDC as a security measure to detect real-time intrusions...
The tremendous growth in the amount of available web services (WS) impulses many researchers on proposing recommender systems to help users discover services. Most of the proposed solutions analyzed query strings and web service descriptions to generate recommendations. However, text based recommendations approaches depend mainly on user's perspective, languages and notations which easily decrease...
Creating semantically consistent multilingual vocabulary is challenging to concept engineering, natural language process (NLP) and collaborative editing for cross-domain meaning understanding. This paper proposes a novel method of automatic concept mapping (My Lang Mapper) between multilingual dictionaries (same as bilingual dictionary, abbreviated as BD) and the Princeton's WordNet (WN) to derive...
