Research on User Similarity Calculation of Collaborative Filtering for Sparse Data [PDF]

open access: yesJisuanji kexue yu tansuo, 2022
User-based collaborative filtering achieves recommendation for target users based on the preferences of their nearest neighbors, in which how to calculate user similarity is critical.

Self-adaptive GA, quantitative semantic similarity measures and ontology-based text clustering [PDF]

open access: yes, 2008
As the common clustering algorithms use vector space model (VSM) to represent document, the conceptual relationships between related terms which do not co-occur literally are ignored.

Soft Similarity and Soft Cosine Measure: Similarity of Features in Vector Space Model [PDF]

open access: yesComputación y Sistemas, 2014
We show how to consider similarity between features for calculation of similarity of objects in the Vector Space Model (VSM) for machine learning algorithms and other classes of methods that involve similarity between objects. Unlike LSA, we assume that similarity between features is known (say, from a synonym dictionary) and does not need to be ...

Misfire Fault Diagnosis Method of Gasoline Engines Using the Cosine Similarity Measure of Neutrosophic Numbers [PDF]

open access: yesNeutrosophic Sets and Systems, 2015
This paper proposes a distance measure of neutrosophic numbers and a similarity measure based on cosine function, and then develops the misfire fault diagnosis method of gasoline engines by using the cosine similarity measure of neutrosophic numbers.

Cosine Similarity Measure Based Multi-attribute Decision-making with Trapezoidal Fuzzy Neutrosophic Numbers [PDF]

open access: yesNeutrosophic Sets and Systems, 2015
The objective of the study is to present cosine similarity measure based multi-attribute decision making under neutrosophic environment. The assesments of alternatives over the attributes are expressed with trapezoidal fuzzy neutrosophic numbers in which

Unsupervised Measure of Word Similarity: How to Outperform Co-occurrence and Vector Cosine in VSMs

open access: yes, 2016
In this paper, we claim that vector cosine, which is generally considered among the most efficient unsupervised measures for identifying word similarity in Vector Space Models, can be outperformed by an unsupervised measure that calculates the extent of ...

Research on the Application of User Recommendation Based on the Fusion Method of Spatially Complex Location Similarity

open access: yesComplexity, 2021
Since the user recommendation complex matrix is characterized by strong sparsity, it is difficult to correctly recommend relevant services for users by using the recommendation method based on location and collaborative filtering.
