Reasoning with Temporal Context in News Analysis
نویسندگان
چکیده
One aspect of implicit, contextual information is its temporal component. Explicating this component in a formal model makes it possible to disambiguate some context-dependent expressions and discover connections between expressions. We have implemented and extended Allen’s algebra of temporal intervals in a reasoner that takes into account the linear nature of time and the granularity of temporal expressions (days/weeks/...). If this algebra is used to model the temporal extension of events, the reasoner can track and connect the reference of indexical expressions about them. We intend to use the reasoner for analysing news streams, to help discover connections between news items.

Context-aware Modeling for Spatio-temporal Data Transmitted from a Wireless Body Sensor Network
Context-aware systems must be interoperable and work across different platforms at any time and in any place. Context data collected from wireless body area networks (WBAN) may be heterogeneous and imperfect, which makes their design and implementation difficult. In this research, we introduce a model which takes the dynamic nature of a context-aware system into consideration. This model is con...
متن کاملDeveloping Geo-temporal Context from Implicit Sources with Geovisual Analytics
The key Geovisual Analytics research question addressed in this paper is how knowledge of past situations can be computationally extracted from heterogeneous and implicit information spaces and presented as visual artifacts within an interactive environment to facilitate reasoning about situations from geographic and temporal (or geo-temporal) contextual perspectives. This paper in particular w...
متن کاملRamiication Analysis with Structured News Reports Using Temporal Argumentation (draft Paper)
To operate in the real-world, intelligent agents constantly need to absorb new information, and to consider the ramiications of it. This raises interesting questions for knowledge representation and reasoning. Here we consider ramiication analysis in which we wish to determine both the likely outcomes from events occuring and the less likely, but very signiicant outcomes, from events occuring. ...
متن کاملMixed Qualitative/Quantitative Dynamic Simulation of Processing Systems
In this article the methodology proposed by Li and Wang for mixed qualitative and quantitative modeling and simulation of temporal behavior of processing unit is reexamined and extended to more complex case. The main issue of their approach considers the multivariate statistics of principal component analysis (PCA), along with clustered fuzzy digraphs and reasoning. The PCA and fuz...
متن کاملExperiments with Reasoning for Temporal Relations between Events
Few attempts have been made to investigate the utility of temporal reasoning within machine learning frameworks for temporal relation classification between events in news articles. This paper presents three settings where temporal reasoning aids machine learned classifiers of temporal relations: (1) expansion of the dataset used for learning; (2) detection of inconsistencies among the automati...
