Semantic Trajectory Similarity based on Chronological Aspects

Semantic-Geographic Trajectory Pattern Mining Based on a New Similarity Measurement

Trajectory pattern mining is becoming increasingly popular because of the development of ubiquitous computing technology. Trajectory data contain abundant semantic and geographic information that reflects people’s movement patterns, i.e., who is performing a certain type of activity when and where. However, the variety and complexity of people’s movement activity and the large size of trajector...

Computing Semantic Similarity of Documents Based on Semantic Tensors

Exploiting semantic content of texts due to its wide range of applications such as finding related documents to a query, document classification and computing semantic similarity of documents has always been an important and challenging issue in Natural Language Processing. In this paper, using Wikipedia corpus and organizing it by three-dimensional tensor structure, a novel corpus-based approa...

Classification based on 3-similarity

Similarity concept, finding the resemblance or classifying some groups of objects and study their common properties has been the interest of many researchers. Basically, in the studies the similarity between two objects or phenomena, 2-similarity in our words, has been discussed. In this paper, we consider the case when the resemblance or similarity among three objects or phenomena of a set, 3-...

Scalable Trajectory Similarity Search Based on Locations in Spatial Networks

In this paper, we propose an efficient query processing algorithm that returns the trajectory results in low search time. We limit the calculation of pairwise shortest path distances between the set of query locations and the spatial nodes, by highly reducing the preprocessing requirements. Also, we introduce a spatiotemporal similarity measure, based on which the temporal-to-spatial significan...
