Several factors hinder information retrieval in the medical profession. Consumers (layman people) often struggle to learn medical terms. Because medical terms are more evident to professionals, it is difficult for consumers to construct a query using medical terms. Consumers would find it easier to access relevant medical information if medical wor...

Sentiment analysis is difficult nowadays when we collect data from social media sites as people from every walk of life come there and write their opinion about various things. Social media is very powerful, but it has a lot of liberty too. People while posting text online do not give any importance about how grammatically correct they are. Moreove...

Faces are the most common biometric used for the identification of a person. Law enforcement agencies use face as a key point to identify the suspect involved in unlawful activities. Forensic sketches are normally developed by the sketch artist based on verbal details provided by an eyewitness about the suspect. In a forensic sketch, the facial des...

Code-mixing on social media is a trend in many countries where people speak multiple languages, such as India, where Hindi and English are major communication languages. Sentiment analysis is beneficial in understanding users’ opinions and thoughts on social, economic, and political issues. It eliminates the manual monitoring of each and every revi...

The sentiment is opinion or thought about a particular product or a specific situation. Sentiment analysis is applied to extract the subject information from text. Sentiment is computed using feature level, entity level, sentence level, document level. This paper proposed a sentiment detection tool that detects the sentiment (positive or negative)...

This paper gives an overview of various CBIR (Content-Based Image Retrieval) Techniques. CBIR is a system that utilizes different image features, like texture, color, and shape information, to fetch different images from a huge database. CBIR systems are mostly used in the medical field as they collect images from a huge database depending on the s...

Social media have earned fame for consuming the news due to their quick proliferation and availability. However, they are also the main contributor in spreading fake news. Fake images spread over microblogging platforms like Twitter generates misrepresentation and arouses destructive emotions in consumers. This makes the detection of fake images ov...

Today, a massive outbreak of a deadly virus has challenged humanity in each aspect; we deemed ourselves powerful. Millions of people are at risk, and in some cases, even if the person has reported negative, it is relapsing. Globally, data scientists are also working to tackle this issue by diagnosing, predicting it with the help of machines. Artifi...

With the ongoing covid-19 pandemic, people rely on online communication to remain connected as a precautionary measure to maintain social distancing. When we have no one on our side to listen and console us in state of fear and dilemma, we try to find comfort in anonymity of social media. Tracking real-time changes in sentiments are quite difficult...

Query reformulation (QR) is the process to make initial query exact by generating more significant terms. Term extraction and selection are one of the techniques of it. QR eliminates irrelevant and repetitive terms from the top ranked documents and upgrades the effectiveness of IR system. There are various term extraction and selection methods, and...

The technology revisions are too quick to resist or stay apart. Most of the work, on massive and streaming data, tries to scale up the computation. The scale up and scale out comes with its own set of advantages and disadvantages. The computational hardware has already been used to its limits with best of the algorithms. Our work proposes and imple...

Thousands of faces can be remembered by a single individual. Faces with diverse shapes, sizes, and colors might be recalled. People are distinguished from one another by their face form and color, which makes them easier to recall. A person’s face is a crucial element for identifying them. When someone interacts with an unfamiliar individual, the p...

Spotting fake news is a critical problem nowadays. Social media are responsible for propagating fake news. Fake news propagated over digital platforms generates confusion as well as induce biased perspectives in people. Detection of misinformation over the digital platform is essential to mitigate its adverse impact. Many approaches have been imple...

Microblogging applications are currently used to disseminate information with concise text and images. Nevertheless, they are also the largest platform for circulating forged images.
