Semantic Mapping of Events

چکیده
This paper addresses the problem of e cient management of events, in particular in those environments where events carry information useful to multiple applications, possibly operating in di erent domains and at di erent levels of abstraction. We investigate the problems and opportunities o ered by such environments, and de ne a framework that enables a semantic mapping of events, i.e., enables the processing and successive re nement of events at di erent levels of abstraction, so that they can be understood and e ciently consumed by business applications. We identify the requirements of an event mapping system and present a speci cation language, integrating high-level Petri nets and database query languages, which provides the required expressive power to specify complex event processing functions and includes a set of constructs that support the design process and allows e cient implementations.

The Effect of Semantic Mapping on Reading Comprehension
The research reported here examined the relative effectiveness of semantic mapping, as an interactive pre-reading strategy, on reading comprehension of Iranian undergraduate students (non-EFL majors). It also examined whether there was an interaction between gender and the effect of teaching semantic mapping strategy on reading comprehension. The participants in this study consisted of 120 male...

Traditional and modern vocabulary instruction techniques have been introduced in the past few decades to improve the learners’ performance in reading comprehension. Semantic mapping, which entails drawing learners’ attention to the interrelationships among lexical items through graphic organizers, is claimed to enhance vocabulary learning significantly. However, whether this technique suits all...

متن کاملTeaching Vocabulary through Semantic Mapping as a Pre-reading Activity across Genders
This study has examined the effect of semantic mapping on learning vocabulary across genders. The researchers selected 120 intermediate students after the administration of a standard proficiency test. A vocabulary test was also used to measure the students’ vocabulary knowledge. The experimental group received semantic mapping in the pre-reading stage, butthe control group did not receive this...
