We describe our contribution to the SemEval task on Frame-Semantic Structure Extraction. Unlike most previous systems described in literature, ours is based on dependency syntax. We also describe a fully automatic method to add words to the FrameNet lexical database, which gives an improvement in the recall of frame detection.

Effective communication in open environments relies on the ability of agents to reach a mutual understanding of the exchanged message by reconciling the vocabulary (ontology) used. Various approaches have considered how mutually acceptable mappings between corresponding concepts in the agents’ own ontologies may be determined dynamically through argumentation-based negotiation (such as Meaning-...

Probing technologies are assumed to augment and speed inquiry learning. However, in practice, handheld-based classroom practice is regarded as only having scratched the surface of what is possible. The purpose of this article is to propose regarding the probe as a catalyst for negotiating meaning in inquiry learning activities rather than to perceiving the devices simply as educational computin...

This paper explains the principles of dependency analysis by reduction and its correspondence to the notions of dependency and dependency tree. The explanation is illustrated by examples from Czech, a language with a relatively high degree of word-order freedom. The paper sums up the basic features of methods of dependency syntax. The method serves as a basis for the verification (and explanati...

For the past two decades linguists working within the framework of systemic functional linguistics have been developing appraisal theory as a tool for analysing evaluation in discourse. In this talk I will present a brief overview of the current model and then move on to address a number of the challenges that have arisen over the years including distinguishing inscribed from invoked attitude, ...

This paper describes a survey of technologies and to what extent they support virtual project based learning. The paper argues that a survey of learning technologies should be related to concrete learning tasks and processes. Problem oriented project pedagogy (POPP) is discussed, and a framework for evaluation is proposed where negotiation of meaning, coordination and resource management are id...

The Internet globally connects a great deal of diverse and heterogeneous information resources, which an agent can dynamically combine in order to synthesise new information. An agent society is used to facilitate a common project within globally distributed, heterogeneous organisations. Besides coordinating a finite number of variables, the agents are used to iron out cultural differences with...
