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...
A solvable model for homopolymers and self-similarity near critical point
Gibbs measure homopolymer zero-range potential phase transition glob- ular phase diffusive phase
2015/9/28
We consider a model for the distribution of a long homopolymer with an at- tractive zero-range potential at the origin in R3 (polymer pinning and de-pinning). The distribution can be obtained as a lim...
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 ...
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...
INTEGRATION OF TERRESTRIAL LASER SCANNING POINTS AND 2D FLOOR PLANS BASED ON MAXIMUM SEQUENTIAL SIMILARITY
TLS Point Cloud Floor Plan Integration CAD Matching Registration
2012/9/3
This paper presents a Maximum Sequential Similarity Reasoning (MSSR) algorithm based method for co-registration of 3D TLS data and 2D floor plans. The co-registration consists of two tasks: estimating...
Prototypicality Gradient and Similarity Measure: A Semiotic-Based Approach Dedicated to Ontology Personalization
Semantic Measure Conceptual Prototypicality Lexical Prototypicality Gradient Ontology Personalization Semiotics
2010/3/16
This paper introduces a new approach dedicated to the Ontology Personalization. Inspired by works in Cognitive Psychology, our work is based on a process which aims at capturing the user-sensitive rel...

Magnetic feld Thermal radiation Viscous dissipation Forced convection
2009/10/10
Magnetohydrodynamic (MHD) forced convection heat transfer from radiate surfaces in the presence of a uniform transverse magnetic eld, with conductive fluid suction or injection from a porous plate is...
A New Method for Calculating Similarity between Sentences and Application on Automatic Abstracting
sentence similarity automatic abstracting lexrank sentence-weight computing redundancy resolution
2009/7/31
Sentence similarity computing plays an important role in machine question-answering systems, machine-translation systems, information retrieval and automatic abstracting systems. This article firstly ...

2008/7/30
Purpose: The main reason for starting research concerning theory of constructional similarity was need to substitute traditional method of creating ordered families by new algorithmic methods orientat...
Job Information Retrieval based on Document Similarity
Job Information Retrieval based Document Similarity
2008/1/15
Job information retrieval (IR) e xhibits unique characteristics com-pared to common IR task. First, searching precision on job posting full text is low because job descriptions cannot be properly used...
Self-Similarity and Internet Performance
Long Range Dependence (LRD) Quality of service (QoS) Voice over Internet Protocol (VoIP) Round Trip Time (RTT)
2004/11/17
In this work, it has been demonstrated through experiments that Long Range Dependence (LRD) in internet traffic is indeed affecting the queueing performance. Queueing performance is being degraded as ...
The k-nearest neighbours (kNN) is a simple but effective method for classification. Its major drawbacks are (1) low efficiency, and (2) dependency on the selection of a “good value” for k. In this pap...
