Towards a Complete Event Type Taxonomy
نویسندگان
چکیده
We present initial results of our effort to build an extensive and complete taxonomy of events described in news articles. By crawling Wikipedia’s current events portal we identified nine top–level event types. Using articles referenced by the portal we built a event type classification model for news articles using lexical and semantic features and present a small–scale manual evaluation of its results. Results show that our model can accurately distinguish between event types but its coverage could still be significantly improved.

Auditory Event Structure and Speech
Auditory events structure much of the perceived world. Sometimes, two or more sounds are perceived as related, and pertaining to a single event. No well-worked out taxonomy yet exists for auditory events. We consider two-part sounds, perceived as cause and effect (loosely interpreted). Many such sounds occur in ambient environments, and of those, many have suggestively rightor left-headed types...
متن کاملA Novel Comprehensive Taxonomy of Intelligent-Based Routing Protocols in Wireless Sensor Networks
Routing in ad-hoc networks, specifically intelligent-based ones, is a highly interested research topic in recent years. Most of them are simulation-based study. Large percentages have not even mentioned some of the fundamental parameters. This strictly reduces their validity and reliability. On the other hand, there is not a comprehensive framework to classify routing algorithms in wireless sen...
متن کاملUsing Bloom’s Revised Cognitive Skills Taxonomy To Evaluate Iranian Students’ Pre-University English Textbook and University Entrance Exams
The priority attributed to the use of Bloom’s revised cognitive skills taxonomy in any educational system and the scarcity of research on this type of topic in our EFL context, the researchers attempted to conduct this study. Our primary objectives revolved around these dimensions. To examine if the pre-university teaching materials (English 1 and 2) assigned and employed by t...
متن کاملTowards Taxonomy of Errors in Chat-oriented Dialogue Systems
This paper presents a taxonomy of errors in chat-oriented dialogue systems. Compared to human-human conversations and task-oriented dialogues, little is known about the errors made in chat-oriented dialogue systems. Through a data collection of chat dialogues and analyses of dialogue breakdowns, we classified errors and created a taxonomy. Although the proposed taxonomy may not be complete, thi...
متن کاملA Computational Model for the Dynamical Learning of Event Taxonomies
We present a computational model that can learn event taxonomies online from the continuous sensorimotor information flow perceived by an agent while interacting with its environment. Our model implements two fundamental learning biases. First, it learns probabilistic event models as temporal sensorimotor forward models and event transition models, which predict event model transitions given pa...
