A Semantic Image Search Engine

We realize we could make image search experience better by understanding users intent and deliver results based on it. Atleast, for high volume queries this could significantly skyrocket user experience. Let me explain how and why.

Image Search results page on Google,Bing and Yahoo for the teen sensation "Justin Bieber" which is one of the most popular query on image search has been more or less static since past few years. I see the same old images of justin bieber. But my experience on web results page for this term is totally different. I see couple of fresh News results at the top, followed by latest justin bieber videos posted on youtube, followed by realtime tweets and then comes static web links at the bottom. First half of the web results page is dynamic and keeps changing the moment fresh content is available on the web. Why not image search? Justin Bieber has been searched over 50 million times in 2010 on image search itself. This number is huge and by 2015 we can expect over 100 million queries for this term given his fame and popularity. So why on earth are users searching for this term again and again? From users feedback, we realize they are looking for fresh image content.

Lets dive directly into how we cater to users intent and help them get the content they are looking for in quickest possible time.

Today, a search for 'justin bieber' on NachoFoto would show the following suggestions next to image results.

Justin Bieber Madame Tussauds
Justin Bieber Miley Cyrus
Justin Bieber Selena Gomez
Justin Bieber NBA All-Star
Justin Bieber Grammy Awards
Justin Bieber Super Bowl
Justin Bieber Ozzy Osbourne
Justin Bieber Never Say
Justin Bieber Golden Globe Awards
Justin Bieber Death Threats
Justin Bieber Chris Brown
Justin Bieber Z100 Jingle Ball
Justin Bieber German TV

Yesterday, the 17 year old social media king's wax figure were unveiled at Madame Tussauds wax museums in New York, Amsterdam and London. As expected, we saw the term 'justin bieber' in google trends hot list for few hours yesterday. This leaves little doubt that in those few hours millions of justin bieber fans were looking for newest wax figure pictures of the singer. If you do a quick search for 'justin bieber' on Google and Bing images, you will not see a single latest wax figure pic. Suprisingly, even a search for 'justin bieber wax figure' or 'Justin Bieber Madame Tussauds' on Google and Bing wouldn't let you find latest pictures.

At NachoFoto, we are trying to address this problem by showing a list of fresh suggestions so that users have a choice and can express that they want just one type of results. 'Justin Bieber Madame Tussauds' is right at the top of suggestions list and it shows latest pictures of the singers wax figure. NachoFoto also makes its users aware of content they are not looking for but might be interested in. If you look at the suggestions list above, you will notice that users have a choice to browse pictures of justin bieber from the recent Grammy Awards or the Golden Globe Awards or with his girlfriend Selena Gomez from the Oscars.

NachoFoto's Semantic technology leverages fresh content on the web to find Suggestions unlike existing search engines that uses users searching pattern. Though using users searching pattern works for many queries, we realize there are many high volume and trending queries for which this approach does not give optimum results.

We have a vision of delivering freshest and most relevant 'Related searches' for as many queries on image search so that users get what they are looking for in just one click. We are just getting started though, so stay tuned.

Introducing Timeline in Image Search

Timeline is a fun way to explore images if you are one of those users who just don't want to miss a single new image of your favorite celebrity, sports-star, automobile, gadget, event or trends in fashion. Users can choose to view latest images, oldest images, or changes over time.

If you are a big fan of Tiger Woods, with one click you could browse his images from various tournaments he has played in past one year. The first screenshot is the image search results page for Tiger Woods.

If you click on any one of the spikes in the timeline, you will see how we show timeline for the particular month you just selected. For example, if you click on October you will see tiger woods images from the Ryder Cup held in Europe.

Early November you will see images from WGC-HSBC Champions event in Shanghai

Mid November
you will see images from JBWere Masters, held near Melbourne, Australia

Early December
you will see images from Chevron World Challenge held in California

January last week you will see images from Farmers Insurance Open held near San Diego

and so on....

Enhancing user experience on image search has always been our top priority. With the Timeline feature we have taken just another step in that direction.

Straight from NachoFoto Labs ~ "Related Searches" Comparision Chart in Image Search

Our Search Quality Evaluation team conducted an experiment to compare "Related searches" shown by Google Images, Bing Images, Yahoo Images and NachoFoto for over a thousand queries. Below you will see "Related searches Comparision chart" for some of the queries and our conclusion.

Note: ”HTC” case study was conducted on 17th Jan’11 ~ Results on Nachofoto might have changed if you search for HTC today

“HTC” is one of the popular search query in “Gadgets & Technology” category.
Given the fact that a new HTC model is launched every 2-3 weeks, there is no doubt that users are looking for latest smartphone models of HTC. And we can also be very sure that users won’t be interested in models as old as 2008 or 2009 or even six months old HTC model.

If you see Related searches offered by Google Images, Bing Images and Yahoo images, most of the HTC models were launched between 1-3 years ago.
If you compare those with Nachofoto results, you will see that the top 2 results
“HTC Evo Shift 4G” and “HTC Thunderbolt” were launched to public few days before we conducted this experiment and the 3rd one “HTC 7 Pro” was launched just few weeks ago.

Lets take a look at another interesting example from Entertainment category.

Note: ”Miley Cyrus” case study was conducted on 17th Jan’11 ~ Results on Nachofoto might have changed if you search for Miley Cyrus today

We have seen the term “Miley Cyrus” appearing in “google trends” and/or “google insights for image search” atleast once every week. In past two months number of searches for ‘Miley Cyrus” skyrocketted when
1. her leaked pictures of smoking salvia with bong hit the web
2.first pictures of her latest album ‘So Undercover’ were made public on the
3.she threw her 18th birthday party
4.first pictures of her album ‘Who owns my heart’ were released on the web

Now it is quite obvious that most of the users want to see fresh and latest images and not the old ones shown by existing image search engines.
If you take a moment and look at “Related searches” shown by Google,Bing and Yahoo image search engines, it is obvious that most of the users are not actually looking for that.
Instead they would be most interested in exploring images of her very own recent birthday party or her pics from American music awards or from the MTV music awards or her leaked smoking pictures and so on.

Offering “Fresh” results has always been one of the most important goals of a search engine and Image Search is no exception. Most users don’t want out of date information.
By offering “Fresh Related searches” image search engines will not only gives their users an opportunity to explore content they are looking for but also enhances overall user experience on image search. Users get what they are looking for and has every good reason to browse more images and spend more time on image search.
