Knowledge Representation Sample Clauses

Knowledge Representation. In order to realistically model the domains we employ several ontologies. We developed an OWL ontology to represent the WS-Agreement schema. This ontology contains the concepts from the schema such as Guarantee, Scope, and ServiceLevelObjective with relationships between them. In addition to the significant elements from the WS-Agreement, we have also included the common predicates from the WSLA specification [25]. We allow the user to add additional predicates to this ontology to preserve flexibility. An instance of this ontology is created for each agreement that is introduced into the system where they can be queried and reasoned easily. Most of the guarantees are asserted over quality of service (QoS) concepts; therefore the QoS ontology as described in [12] defines such concepts as failureRate, latency, throughput, availability, and responseTime. In addition to these ontologies a third OWL ontology represents domain specific knowledge. For our scenario in e-commerce and its implementation we are using the RosettaNet ontology (xxxx://xxxxx.xx.xxx.xxx/projects/meteor- s/wsdl-s/ontologies/rosetta.owl), also represented in OWL. Depending on the application, alternative or additional domain ontologies could be used. Finally, we use the OWL time [14] ontology to represent temporal concepts such as endTime, interval, dayOfWeek, and seconds. These ontologies are used to provide a commonality of terms between agreement parties and to provide rich domain knowledge to the search engine so that it may achieve the best possible match results. when: Agreement (A) and hasGuarantee (A,G) and hasSLO (G, SLO) and hasExpression(SLO, E) and hasPredicate(E, P) and hasType(P, “PercentageLessThanThreshold”) and hasPercentage(E, percent) do: if (percent<=x) then assert hasType(P, “less”) else assert hasType(P, “greater”) The above ARL rule looks for any expression which contains the predicate “PercentageLessThanThreshold” and if the percentage less than x it changes the predicate to “less” otherwise it changes it to “greater”. In many cases the value of x is dependent upon the parameter. For example, a user may require a high percentage for responseTime but may be more lenient about other parameters. This feature can be further customized by adding additional statements in the when segment which perform parameter checks. Predicate=percentageLessThanThreshold Parameter=”qos:responseTime” Value=5 Percent=99 Unit=”time:Seconds Predicate=less Parameter= qos:responseTime Value=6 ...

If a grievant selects a Union Grievance Representative to represent him in a grievance which has been properly filed in accordance with this Article, the Union Grievance Representative may be allowed a reasonable amount of annual leave to investigate the grievance. Such annual leave shall be subject to prior approval by the Union Grievance Representative’s immediate supervisor; however, approval of such leave will not be withheld if the Union Grievance Representative can be allowed such time off without interfering with, or unduly hampering the operations of the unit to which the Union Grievance Representative is regularly assigned. When a grievant has elected Union representation, both the grievant and the Union Grievance Representative shall be notified of a Step 1 meeting. Written communication concerning the grievance or its resolution shall be sent to the grievant and the Union Grievance Representative, and the decision agreed to by the state and the Union shall be binding on the grievant. (B) If the employee is not represented by the Union, an adjustment of the grievance shall be consistent with the terms of this collective bargaining Agreement. The Union shall be given reasonable opportunity to be present at a meeting called for the resolution of such grievance. A grievant using this procedure in the processing of a grievance will be bound by the procedure established by the parties to the Agreement. (C) The Executive Director of the Union shall furnish to the state a list of Union Representatives and the state will not recognize a person as a Union Representative whose name does not appear on the list. (D) If a grievance meeting, mediation, or arbitration hearing is held or requires reasonable travel time during the work hours of grievant, a representative of the grievant, or any required witnesses, such hours shall be deemed time worked. Attendance at grievance meetings, mediation, or arbitration hearings outside of a participant’s regular work hours shall not be deemed time worked. The state will not pay the expenses of participants attending such meetings on behalf of the Union.

  • Employee Representation Clauses 50, 51 and 52 of this Agreement outline the rights for Employee representatives and Union Delegates when assisting Employees.
