SIMILARITY AMONG MULTIPLE GEOGRAPHIC REPRESENTATIONS
Multiple Representation Information Integration Dataset ambiguity
2016/2/29
A key ingredient of systems aiming to cope with multiple representations of geographic features is some method for assessing the
correspondence and similarity of such representations. In other words,...
Efficient Similarity Join and Search on Multi-Attribute Data
Similarity Search Similarity Join Multi-Attribute Data
2016/1/22
In this paper we study similarity join and search on multi-attribute data. Traditional methods on single-attribute data have pruning power only on single attributes and cannot efficiently support mult...
Measuring Semantic Similarity by Latent Relational Analysis
analogies semantic relations vector space model noun-modifier expressions latent relational analysis
2015/7/31
This paper introduces Latent Relational Analysis (LRA), a method for measuring semantic similarity. LRA measures similarity in the semantic relations between two pairs of words. When two pairs have a ...
Retrieval of Patent Documents from Heterogeneous Sources using Ontologies and Similarity Analysis
Patent Court cases Information Retrieval Knowledgebase
2015/6/30
In the past few years, there has been an explosive growth in scientific and legal information related to the patent system. Patents and related documents are siloed into multiple heterogeneous sources...
Utilizing Statistical Semantic Similarity Techniques for Ontology Mapping– with Applications to AEC Standard Models
ontology mapping similarity analysis information interoperation statistical analysis techniques
2015/6/30
In the Architecture, Engineering and Construction (AEC) industry, there exist a number of ontological standards to describe the semantics of building models.Although the standards share similar scopes...
Cosine Similarity Scoring without Score Normalization Techniques
Cosine Similarity Scoring Score Normalization Techniques
2014/11/27
In recent work [1], a simplified and highly effective approach to speaker recognition based on the cosine similarity between lowdimensional vectors, termed ivectors, defined in a total variability spa...
Modeling Dyadic Attunement: Physiological Concordance in Newly Married Couples and Alliance Similarity in Patient-Therapist Dyads

2014/11/5
Mutual influence within relationships is theorized as central to human development and functioning across the lifespan. Multiple theories posit a process of progressive bidirectional influence that re...
NetSimile: A Scalable Approach to Size-Independent Network Similarity
NetSimile Scalable Approach Size-Independent Network Similarity
2012/11/23
Given a set of k networks, possibly with different sizes and no overlaps in nodes or edges, how can we quickly assess similarity between them, without solving the node-correspondence problem? Analogou...
Metric distances derived from cosine similarity and Pearson and Spearman correlations
Metric distances derived cosine similarity Pearson and Spearman correlations
2012/9/17
We investigate two classes of transformations of cosine similarity and Pearson and Spearman correlations into metric distances, utilising the simple tool of metric-preserving functions. The rst class...
Forgiving Significant Interpersonal Offenses: The Role of Victim/Offender Racial Similarity
Forgiveness Race Cultural Psychology Counseling
2013/2/22
The influence of victim/offender racial similarity on victim forgiveness was investigated in a study of interpersonal transgressions. It was hypothesized that racial similarity between victim and offe...
Estimating correlation and covariance matrices by weighting of market similarity
Weighted Correlation Estimation Covariance Estimation Time-dynamic Dependence
2010/10/20
We discuss a weighted estimation of correlation and covariance matrices from historical financial data. To this end, we introduce a weighting scheme that accounts for similarity of previous market co...
