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.
Topic : Upgrading Your Technical Skills During Pandemic Using Available Local and International Online Seminar, Training and Certifications
The pandemic (COVID-19) has brought a lot of catastrophic effects, not only here in the Philippines but all over the world. During this pandemic and the time of lock down, people procrastinated a lot, worst case is that, some people have suffered from some mental health issues and illnesses. As a student who have locked down for almost four months, I instead have maximized my time on finding ways on how to improve my technical skills and knowledge by engaging and involving myself in some of available Online Seminars, Training and Certifications here and abroad. Here are the list of some websites for technical Seminar and Training.

The life of an influencer.
Our lives are hard , no doubt we go through the daily struggle to come up with great combination clothes , completing our chores, rushing to jobs etc etc. That’s our normal life , could you imagine what an influencer goes through? . Internet personalities , YouTubers , Tumblr models , TikTokers etc are literally suffering from what I like to call the “Hannah Montana syndrome “. These influencers live a normal like us with the added pressure of being famous at the same time and more over ..when we mess up our chores , no body cares but if they mess up it’s all over the Internet. Let’s talk about a recent incident, which was Nico Anderson’s iPhone getting hacked and leaking information about him going for college. There were a minimum of 700 tweets about it within 3 days! Could you imagine that happening with you? I’d rather not. Influential personalities like James Charles , Garima , Nico Anderson/Nishan , Indigotohell etc go through insane amounts of pressure in day to day life , they have to keep their attitude in check , their persona in check , their issues in check , they have create a facade of well being around themselves and give their audience a seamlessly smooth experience. They know the audience is quick to judge, there will always be people who would want nothing more but to throw in hate comments or create rumours regarding their idols . We often forget that these are real people behind the screen who do the things they do for us, and we go on to unleash our anger on them because come on , who cares ? Right ? .
Life of an Influencer is by no means perfect or flawless. They have to fight their own battles, they are haunted by their own demons.
