Sentiment analysis using cosine similarity measure

2015 IEEE 2nd International Conference on Recent Trends in Information Systems (ReTIS), 2015
The opinion of other people is often a major factor influencing our decisions. For a consumer it affects purchase decisions and for a producer or a service provider it helps in making business decisions. Companies spend a lot of money and time on surveys for gathering the public opinion on products and services.

Quantized Directional Cosine measurements based Localization

2021 10th IEEE International Conference on Communication Systems and Network Technologies (CSNT), 2021
Localization of target emitters using multiple simultaneous directional cosine (DC) measurements are popular and extremely useful in radar and sonar surveillance systems. Underwater localization, classification, and target tracking using hydrophone with limited bandwidth constraints is a challenging problem.

Distance and cosine measures of niche overlap

Social Networks, 2001
Abstract Niche overlap is increasingly used as a way of measuring the intensity of interorganizational competition. This paper examines and compares various distance and cosine measures of niche overlap. The analysis in this paper shows that Euclidean distance applied to the raw data as well as to transformed data is not an appropriate measure of ...

A Novel Semianalytic Algorithm for Cosine Transform in ATEM Measurement

IEEE Geoscience and Remote Sensing Letters, 2019
First, we directly introduce the cosine transform to compute the time-domain electromagnetic (EM) response excited by cause step turnoff. Then, we advance a novel semianalytic algorithm based on integration, summation, and cube spline interpolation (ISCSI) method to efficiently accomplish the cosine transform. The ISCSI method divides the integral into

Hyperbolic sine and cosine functions on measure chains

Nonlinear Analysis: Theory, Methods & Applications, 2001
Hyperbolic sine and cosine functions on measure chains are introduced and their basic properties are established. A necessary and sufficient condition for (non)existence of focal points (generalized zeroes) of the hyperbolic cosine and of particular exponential functions on measure chains is found.

Vehicle speed measurement: Cosine error correction

Measurement, 2012
Abstract Although laser devices are commonly used to measure distances and vehicle speed in traffic safety-related studies, they suffer from a drawback known as the cosine effect. Furthermore, such traffic safety studies analyze both vehicle speed and a large amount of geographical data.

Measuring semantic similarity of documents with weighted cosine and fuzzy logic

Journal of Intelligent & Fuzzy Systems, 2020
Currently, the semantic analysis is used by different fields, such as information retrieval, the biomedical domain, and natural language processing. The primary focus of this research work is on using semantic methods, the cosine similarity algorithm, and fuzzy logic to improve the matching of documents.

Reflective optics for cosine-corrected irradiance measurements

Review of Scientific Instruments, 1998
Most of the detectors commonly used for radiometric measurements have a more or less poor cosine response. By means of a reflective entrance optics in front of the detection system, we have reduced relative cosine errors below 5% up to zenith angles of 75°.

Distance Weighted Cosine Similarity Measure for Text Classification

2013
In Vector Space Model, Cosine is widely used to measure the similarity between two vectors. Its calculation is very efficient, especially for sparse vectors, as only the non-zero dimensions need to be considered. As a fundamental component, cosine similarity has been applied in solving different text mining problems, such as text classification, text ...
