Abstract.We show the first detailed realistic e-business application scenario that uses and exploits capabilities of the SweetRules V2.1 toolset for e-contracting using the SweetDeal approach. SweetRules is a uniquely powerful integrated set of tools for semantic web rules and ontologies. SweetDeal is a rule-based approach to representation of business contracts that enables software agents to create, evaluate, negotiate and execute contacts with substantial automation and modularity. The scenario that we implement is of electronic procurement of computers, with request-response iterated B2B supply-chain management communications using RuleML as content of the contracting discovery/negotiation messages. In particular, the capabilities newly exploited include: SweetJess or SweetXSB to do inferencing in addition to the option of SweetCR inferencing, SweetOnto to incorporate/merge-in OWL-DLP ontologies, and effectors to launch real-world actions. We identify desirable additional aspects of query and message management to incorporate into RuleML and give the design of experimental extensions to the RuleML schema/model, motivated by those, that include specifically: fact queries and answers to them. We present first scenario of using SCLP RuleML for rebates and financing options, in particular exploiting the courteous prioritized conflict handling feature. We give a new SweetDeal architecture for the business messaging aspect of contracting, in particular exploiting the situated feature to exchange rulesets, that obviates the need to write new (non-rule-based) agents as in the previous SweetDeal V1 prototype. We finally analyze how the above techniques, and SweetDeal, RuleML and SweetRules overall, can combine powerfully with other e-business technologies such as RosettaNet and ebXML.

Abstract:Corporate household (CHH) refers to the organizational information about the structure within the corporation and a variety of inter-organizational relationships. Knowledge derived from this data is becoming increasingly important for improving data quality in applications, such as Customer Relationship Management (CRM), Enterprise Resource Planning (ERP), Supply Chain Management (SCM), risk management, and sales and market promotion. Extending the concepts from our previous CHH research, we exemplify in this paper the importance of improved corporate household knowledge and processing in various business application areas. Additionally, we provide examples of CHH business rules that are often implicit and fragmented -understood and practiced by different domain experts across functional areas of the firm. This paper is intended to form a foundation for further research to systematically investigate, capture, and build a body of corporate householding knowledge across diverse business applications.

Coronavirus disease 2019 (COVID-19) caused by a single stranded RNA virus originating from Wuhan China has gripped the whole world and evolved rapidly into a public health crisis. SARSCoV-2 (severe acute respiratory syndrome coronavirus 2 is abundantly present in nasopharyngeal and salivary secretions of affected patients and is transmitted by droplets, surface contact, fecal-oral route and by aerosolization during procedures. The dental professionals are particularly at risk because of close contact with the patient and exposure to blood, saliva and droplets. Dental professionals must be fully aware of coronavirus spreading modalities, identification of patients with this infection, so present article introduces the essential knowledge about COVID-19 infection and provide recommended management protocols for dental practitioners based on relevant guidelines, research so that dental professional are better prepared to manage  asymptomatic, suspected, and confirmed COVID-19 patients.
