Reasoning With Uncertain Knowledge
Heuristics derived from human experimentation are integrated with a knowledge network to pro duce a model for reasoning with uncertain information. The believability of knowledge is deter mined by collecting reasons for believing and not believing it. These reasons, or endorsements, are subsequently ordered by their belief, the reliability of their belief, and their importance relative to one...
متن کاملUncertain Temporal Knowledge Graphs
Temporal data can be found in various sources from patient histories, purchase histories, employee histories, to web logs. Recent advances in open information extraction have paved the way for automatic construction of knowledge graphs (kgs) from such sources. Often the extraction tools used to construct kgs produce facts and rules along with their confidence scores, leading to the notion of un...
متن کاملTechniques for Treating Uncertain Knowledge-Based Databases
Extant tools currently available for formal modeling, reasoning, decision making and computation in computer engineering are unequivocal, that is, they contains no uncertainties. Certainty indicates that the structures and parameters of the model they are dealing with is assumed to be precisely and totally known, and thus there are no doubts about their values, occurrence and their completeness...
متن کاملMatching Uncertain Identities Against Sparse Knowledge
This paper presents a method for fast matching of data attributes contained in a high-volume data stream against an incomplete database of known attribute values. The method is applied to vessel observational data and databases of known vessel characteristics, with emphasis on vessel identity attributes. Due to the large quantity of streaming observations, it is desirable to compute the best ma...
متن کاملActive learning with uncertain labeling knowledge
Traditional active learning assumes that the labeler is capable of providing ground truth label for each queried instance. In reality, a labeler might not have sufficient knowledge to label a queried instance but can only guess the label with his/her best knowledge. As a result, the label provided by the labeler, who is regarded to have uncertain labeling knowledge, might be incorrect. In this ...
