The majority of modern-day companies store commercially sensitive and valuable information assets in digital form. It is essential for the Chief Information Security Officer (CISO) within an organisation to ensure that such information is adequately protected. External standards exist to advise CISOs on how to secure information, but these are essentially “one-size-fits-all”. Furthermore they d...

Knowledge base building environments must progress in two important directions: (i) increased participation of domain experts in the knowledge design process through new computational models and effective man-machine interfaces; and (ii) automated knowledge acquisition tools to facilitate the overt expression of knowledge. This paper presents the integration of a knowledge acquisition methodolo...

Although an increasing number of RDF knowledge bases are published, many of those consist primarily of instance data and lack sophisticated schemata. Having such schemata allows more powerful querying, consistency checking and debugging as well as improved inference. One of the reasons why schemata are still rare is the effort required to create them. In this article, we propose a semi-automati...

This paper presents a hierarchical heterogeneous knowledge-base model. The model is designed to support manipulation with human knowledge about real or abstract concepts from the real world that are uncertain, ambiguous, vague and fuzzy. It has two levels: a lower associative and a higher semantic. It enables processing of novel concepts in the inheritance and the recognition inference processe...

The basic aim of our study is to give a possible model for handling uncertain information. This model is worked out in the framework of DATALOG. At first the concept of fuzzy Datalog will be summarized, then its extensions for intuitionisticand interval-valued fuzzy logic is given and the concept of bipolar fuzzy Datalog is introduced. Based on these ideas the concept of multivalued knowledge-b...

The Pharmacogenetics Knowledge Base (PharmGKB; http://www.pharmgkb.org/) contains genomic, phenotype and clinical information collected from ongoing pharmacogenetic studies. Tools to browse, query, download, submit, edit and process the information are available to registered research network members. A subset of the tools is publicly available. PharmGKB currently contains over 150 genes under ...

the purpose of this study is evaluating the impact of organizational culture and leadership style on knowledge management considering the mediating role of technology acceptance. the hypotheses were tested against the data collected from a sample of 54 manufacturing companies in qazvin province, using the variance based structural equations modeling (partial least square technique) and path ana...

Expert identification has become an important information retrieval task. We present and investigate a number of approaches for identifying an expert. Different approaches are based on exploiting the structure of documents in the knowledge base. Furthermore, our system highlights the integration of database technology with information retrieval (DB+IR).

Knowledge bases (KB) provide support for real-world decision making by exposing data in a structured format. However, constructing knowledge bases requires gathering data from many heterogeneous sources. Manual efforts for this task are accurate, but lack scalability, and automated approaches provide good coverage, but are not reliable enough for realworld decision makers to trust. These two ap...
