Efficient Subgraph Similarity Search on Large Probabilistic Graph Databases [PDF]

open access: yes, 2012
Many studies have been conducted on seeking the efficient solution for subgraph similarity search over certain (deterministic) graphs due to its wide application in many fields, including bioinformatics, social network analysis, and Resource Description ...

Searchable Public Key Encryption Supporting Semantic Multi-Keywords Search

open access: yesIEEE Access, 2019
Searchable public key encryption (SPE) that supports multi-keywords search, allows data users to retrieve encrypted files of interest efficiently, and thus it has been intensively studied during recent years. However, most existing SPE solutions focus on

Set similarity search beyond MinHash [PDF]

open access: yesProceedings of the 49th Annual ACM SIGACT Symposium on Theory of Computing, 2017
We consider the problem of approximate set similarity search under Braun-Blanquet similarity $B(\mathbf{x}, \mathbf{y}) = |\mathbf{x} \cap \mathbf{y}| / \max(|\mathbf{x}|, |\mathbf{y}|)$. The $(b_2, b_2)$-approximate Braun-Blanquet similarity search problem is to preprocess a collection of sets $P$ such that, given a query set $\mathbf{q}$, if there ...

Multivariate Time Series Similarity Searching [PDF]

open access: yesThe Scientific World Journal, 2014
Multivariate time series (MTS) datasets are very common in various financial, multimedia, and hydrological fields. In this paper, a dimension-combination method is proposed to search similar sequences for MTS. Firstly, the similarity of single-dimension series is calculated; then the overall similarity of the MTS is obtained by synthesizing each of the

A Similarity Measure for Material Appearance [PDF]

open access: yes, 2019
We present a model to measure the similarity in appearance between different materials, which correlates with human similarity judgments. We first create a database of 9,000 rendered images depicting objects with varying materials, shape and illumination.

Similarity search for scientific workflows [PDF]

open access: yesProceedings of the VLDB Endowment, 2014
With the increasing popularity of scientific workflows, public repositories are gaining importance as a means to share, find, and reuse such workflows. As the sizes of these repositories grow, methods to compare the scientific workflows stored in them become a necessity, for instance, to allow duplicate detection or similarity search.
