This research showed that appropriate input and suitable contexts for interaction among students can lead to successful  second language acquisition (SLA). This study based on Swain's (2005) notion of collaborative dialogue, aimed to study whether EFL learners participating in negotiation of meaning based tasks collaborate with each other and, if so, to investigate the role of this behavior in ...

We introduce the flexible approach for determining agents’ orientation on ontology mappings (FDO), which provides a flexible mechanism for agents to decide whether or not they support an argument about a mapping. Whilst this results in agents relaxing some preferences over suitable mappings, it produces a larger consensus of possible mappings due to the generation of a greater number of argumen...

this study was inspired by vanpatten and uludag’s (2011) study on the transferability of training via processing instruction to output tasks and mori’s (2002) work on the development of talk-in-interaction during a group task. an interview was devised as the pretest, posttest, and delayed posttest to compare four intervention types for teaching the simple past passive: traditional intervention ...

Meaning negotiation (MN) is the general process with which agents reach an agreement about the meaning of a set of terms. We give here a general model of MN for two agents, in which each agent discusses with the other one her viewpoint by exhibiting it in an actual set of constraints on the meaning of the negotiated terms. We call this presentation of individual viewpoints an angle. The two age...

Finding a consensus between communities to create an ontology is a difficult task. An evolutionary process where domain experts and knowledge engineers work together intensively is needed to support collaborative communities in defining a common ontology. These communities model their view of a particular concept while knowledge engineers try to find a consensus. Negotiation, finding similariti...

This paper describes an automatic algorithm of meaning negotiation that enables semantic interoperability between local overlapping and heterogeneous ontologies. Rather than reconciling differences between heterogeneous ontologies, this algorithm searches for mappings between concepts of different ontologies. The algorithm is composed of three main steps: (i) computing the linguistic meaning of...

The present study examines the role that multimodality and translanguaging play in scaffolding oral interactions during language-related episodes (LREs) involving meaning negotiation. tasks carried out using synchronous video-based computer-mediated communication were part of a tandem virtual exchange (Spain, Canada). participants, 18 dyads English Spanish college-level learners, conducted thre...
