... Evans and Eyers [65] use EC for encoding deontic clauses in contracts for data use rules and monitoring of subsequent compliance of these rules. Their work is similar to the study of [66] with the exception that the logic programming used in their work is formalised in EC to represent the deontic states explicitly, while the latter is a declarative approach for modeling various contract rules types. Ours is different from these studies as we consider rather complex obligation modalities, and the effects of violations, while they only work on basic deontic notions, i.e., achievement, permissions and prohibitions, with the exception of the work by Elakehal et al. [62] where authors are able to model violations and obligations arising from the violation, yet the notion of perdurant obligations is not covered. ...

... In such a case, each agent is responsible for achieving part of the goal. This cooperation effort has a chance of succeeding only by knowledge and information exchange and effective coordination [3] [4]. ...

... We apply semantic web technologies to device services in order to enable users to focus on the tasks they want to achieve, rather than how to achieve them. To this end we have created a framework called Task Computing [25,19]. In our framework, semantics fulfill two roles: (a) it enables the manipulation of and the interaction with the computing environment at the semantic layer so that users are able to define and execute complex tasks without having to worry about the details of underlying devices and services. ...

... To facilitate communication between agents, we need Agent Communication Language (ACL) [22]. FIPA-ACL is one of the most commonly used languages in MAS [23]. ...

... Researchers [7] have been continuously putting efforts to improve existing ACL according to FIPA standards and also carrying out the task cooperatively to achieve the shared goals. Authors in [8,9,10] have addressed the issue of semantics for KQML, in particular. They described KQML a language and associated protocol by which intelligent software agents can communicate to share information and knowledge. ...

... [4] [5] As businesses and companies need to stay updated on consumer technologies trends to follow their markets and improve their digital tools, the era of conversational agents could be the next-big-thing implemented in their ecosystems. [6][7] [8][9] [10] The focus of this study regards understanding how and in which ways this modern technology could be implemented in the workflows of non-related consumer tasks, but rather in work environment with business questions and goals, both in dimensions of satisfaction and performance over time. ...

... More detailed information regarding knowledge protocols is provided in Oztemel and Tekez (2009c). Similarly, Finin et al. (1995) presented an agent communication language called KQML. This can still be actively used for generating knowledge exchange capabilities between the machines. ...

... As Fig. 3 shows, algorithms in this category train a single (usually complex) classification model to learn the class hierarchy. For example, Labrou and Finin [27] proposed a text-mining classifier to address Yahoo!'s hierarchical categories. It learns the hierarchy using a set of topic prototypes and a classification method resembling Rocchio's document categorization approach [28]. ...

... Thus we saw the development of several agent communication languages intended to provide agents with a repertoire of speech acts, the best known of which was KQML . A semantics for KQML was given in Labrou and Finin (1994). A typical example from KQML is tell (A,B,X), where A tells B that X. ...
