From Data Fusion to Knowledge Fusion
The task of data fusion is to identify the true values of data items (e.g., the true date of birth for Tom Cruise) among multiple observed values drawn from different sources (e.g., Web sites) of varying (and unknown) reliability. A recent survey [20] has provided a detailed comparison of various fusion methods on Deep Web data. In this paper, we study the applicability and limitations of diffe...
متن کاملFrom Data Fusion to Situation Analysis
This paper proposes a new concept, Situation Analysis (SA), in an attempt to merge into a unifying synthesis the main notions put forward by well established data fusion and situation awareness models. In addition to clarifying the original concepts of these models, this synthesis expands on some of these ideas while achieving a fair depth in the level of details and the rigorousness of the res...
متن کاملKnowledge and Data Fusion in Probabilistic Networks
Probability theory provides the theoretical basis for a logically coherent process of combining prior knowledge with empirical data to draw plausible inferences and to refine theories as observations accrue. Increases in the expressive power of languages for expressing probabilistic theories have been accompanied by refinements and adaptations of Bayesian learning methods to handle the more exp...
متن کاملSemantic Knowledge Representations for Soft Data Fusion
ion is the process of highlighting some of the aspects of a thing in order to grasp its characteristics. It is somehow a process of generalization. Abstracting an observable thing leads to a general representation of this reality, which is often called a concept. Data items are unprocessed and uninterpreted symbols. They are elementary descriptions of measurable properties. Information is what ...
متن کاملValuing Indirect Citations in Citation Networks using Data Fusion
Any scientific activity requires awareness of previous related activities. Citation networks are the networks in which each document is compared as a link of a chain with its previous and next documents, and the documents with the highest number of citations are considered as the most effective ones in a domain. Most of the introduced methods use direct citations for valuing the documents. One ...
