Image re-ranking, as an effective way to improve the results of web-based image search, has been adopted by current commercial search engines such as Bing and Google. Given a query keyword, a pool of images is first retrieved based on textual information. By asking the user to select a query image from the pool, the remaining images are re-ranked based on their visual similarities with the query image. A major challenge is that the similarities of visual features do not well correlate with images’ semantic meanings which interpret users’ search intention. Recently people proposed to match images in a semantic space which used attributes or reference classes closely related to the semantic meanings of images as basis. However, learning a universal visual semantic space to characterize highly diverse images from the web is difficult and inefficient. In this paper, we propose a novel image re-ranking framework, which automatically offline learns different semantic spaces for different query keywords. The visual features of images are projected into their related semantic spaces to get semantic signatures. At the online stage, images are re-ranked by comparing their semantic signatures obtained from the semantic space specified by the query keyword. The proposed query-specific semantic signatures significantly improve both the accuracy and efficiency of image re-ranking. The original visual features of thousands of dimensions can be projected to the semantic signatures as short as 25 dimensions. Experimental results show that 25-40 percent relative improvement has been achieved on re-ranking precisions compared with the state-of-the-art methods.
WEB-SCALE image search engines mostly use keywords as queries and rely on surrounding text to search images. They suffer from the ambiguity of query keywords, because it is hard for users to accurately describe the visual content of target images only using keywords. For example, using “apple” as a query keyword, the retrieved images belong to different categories (also called concepts in this paper), such as “red apple,” “apple logo,” and “apple laptop.”
This is the most common form of text search on the Web. Most search engines do their text query and retrieval using keywords. The keywords based searches they usually provide results from blogs or other discussion boards. The user cannot have a satisfaction with these results due to lack of trusts on blogs etc. low precision and high recall rate. In early search engine that offered disambiguation to search terms. User intention identification plays an important role in the intelligent semantic search engine.

Disadvantage of Too Much Technology
By : Sourav Mondal
While I do think that technological advancements have made our lives much easier compared to the hardships faced by our previous generations, I wondered out loud if there is such a thing as “too much technology”.
India has made rapid strides in the technological field.Technology has made our life more easygoing and comfortable than ever before.But these comforts bestowed on us through technological advancements is doing us more harm than good. In 21st century, technology has evolved to accommodate a more convenient lifestyle and meet every need that could possibly need fulfilling. Our entire lifestyle has slowly but surely been completely taken over by technology.This is having an adverse effect on our well-being.
Modern technology has given us everything we want,whenever we want and more than we actually need ,with the result that wehave become a week society.Unlike the older generation,modern-day children do not have the space and freedom of moving about and end up cramped in front of their computers and video games. We live in the world of iPhones, laptops, fitbits, Facebook, Amazon, Uber, Netflix, tons of food delivery apps, etc. Most students today spend long hours staring at their mobile phones either hooked to social media or some other app.
Through technology has greatly contributed to human development,it has it’s flipside and it is adversely affecting our health. Here’s an attempt to highlight the effects of “too much technology” on students by making a pros and cons list.
How 5G technology is critical to India's digital dream
By Sourav Mondal
What is 5G?
It is the next generation cellular technology that will provide faster and more reliable communication with ultra low latency. A government panel report points out that with 5G, the peak network data speeds are expected to be in the range of 2-20 Gigabit per second (Gbps). This is in contrast to 4G link speeds in averaging 6-7 Megabit per second (Mbps) in India as compared to 25 Mbps in advanced countries, it added.
Who does it benefit?
With 5G technology, consumers will be able to download data heavy content such as 8K movies and games with better graphics in just a few seconds. But once 5G becomes commercial, users will be required to change their current devices in favour of 5G-enabled ones.
What will be the economic impact?
5G is expected to create a cumulative economic impact of $1 trillion in India by 2035, according to a report by a government-appointed panel. According to a separate report by telecom gear maker Ericsson, 5G-enabled digitalisation revenue potential in India will be above $27 billion by 2026. Additionally, global telecom industry GSMA has forecast that India will have about 70 million 5G connections by 2025.
5G deployment will require overcoming several technological and operational challenges, the biggest one being extensive fiberisation. Most operators are at about 20-25% fiberisation. However, a truly 5G experience will require upwards of 80% fiberisation. The antennae will also need to be upgraded at every site while requiring virtualisation of the core and the access with an entirely new orchestration layer to achieve the critical feature of 5G network slicing.
What about spectrum auction?
The government plans to undertake spectrum auction in the current calendar year. In a first step towards preparing for these auctions, the Telecom Regulatory Authority of India (TRAI) had in August last year recommended that entire available spectrum be put to auction in the forthcoming sale. As a result a total of 8,644 MHz of spectrum will be put on sale, making it the largest ever such auction. The total base price of the total airwaves on sale is about ₹4.9 lakh crore.
Apart from creating a positive environment for 5G’s launch in India, the biggest issue GoI needs to resolve is to help telcos overcome the prevailing financial crisis.
The spectrum policy should focus on incentivising heavy investment in 5G, including support for long-term, exclusive, technology-neutral spectrum licences, instead of trying to look for financial windfall right away.
The shift from 4G to 5G is not incremental in nature, but transformational. Given what it means for the entire ecosystem, skipping it is not a choice India can afford.
