Open Mind Word Expert is an implemented active learning system for collecting word sense tagging from the general public over the Web. It is available at http://teach-computers.org. We expect the system to yield a large volume of high-quality training data at a much lower cost than the traditional method of hiring lexicographers. We thus propose a Senseval-3 lexical sample activity where the tr...

The evaluation of an implication by Imaging is a logical technique developed in the framework of modal logic. Its interpretation in the context of a “possible worlds” semantics is very appealing for IR. In 1994, Crestani and Van Rijsbergen proposed an interpretation of Imaging in the context of IR based on the assumption that “a term is a possible world”. This approach enables the exploitation ...

We present a learning architecture for lexical semantic classification problems that supplements task-specific training data with background data encoding general “world knowledge”. The model compiles knowledge contained in a dictionaryontology into additional training data, and integrates task-specific and background data through a novel hierarchical learning architecture. Experiments on a wor...

We prove some fixed point theorems for nonexpansive selfand non-self-mappings in product spaces; in particular, we provide a constructive proof of a result of Kirk and Martinez and a partial answer to a question of Khamsi. Our proofs are elementary in the sense that we do not use any universal (or ultra) nets.

teachers’ sense of efficacy belief has been introduced as a context-specific construct, but the related literature is not clear on this specificity. this study was an attempt to show how contextual factors influence efficacy beliefs among english language teachers. to this end, thirty iranian efl teachers working in both school and private institute contexts were chosen as the participants to r...
