Dygest Your Search

| March 19th, 2009

Update: This hack won the coveted ‘Search’ category award.

For the last couple of days, I and @sudheer_624 have been busy working on this hack for a Yahoo! Hackday. Although still a prototype, the hack has turned out to be interesting so we thought of putting it out for others to play around with.

Dygest (pronounced as ‘digest’ – thanks to @bluesmoon) is aimed at changing the conventional way of displaying search context via a snippet to a more informative, machine generated document summary. There two kinds of relevance for evaluating search results:

  • Vertical relevance: determined by the ranking algorithms.
  • Horizontal relevance: the contextual information made available to the user about the result – Searchmonkey is a good initiative on this front.

The current way of displaying this context is via a snippet of text under every result. This snippet shows the neighborhood of the occurrence of the query terms. Usually this information is not rich enough for a searcher to make the right judgement about the result. This causes the searcher to switch back and forth between the documents and the search results if the the page is not relevant. This can be frustrating at times.

Dygest aims to solve this by either replacing or enhancing the current search snippet with a summary of the result page. At its core lies a summarization engine which figures out what the *real* content of the page is (distinguishing it from the other junk like surrounding text, navigational text, comments etc) and then performs text summarization on this content. The summary of the page is then displayed to the user via the appropriate interface. How cool is that?

The user no longer needs to click on irrelevant links. He/She can perceive the theme/important facts of the page from right within the results page. The other advantage of this is that it gives the user a good overview of the query topic – he no longer needs to spend time reading many long documents but rather read a few summaries from the top results to get a good overview of the subject. This is particularly well suited for mobile devices where its frustrating to switch back and forth between pages and the search results. This is also fit for news articles where we just need the important facts about the story.

Well, here is an example to convince you. A search for ‘Carol Bartz’ yields the following result which at the first glance is not at all informative.

Enhancing the existing view with an abstract of the page helps gauge the content and theme of the document. This would now look like:

Dygest outputs the following summaries for the query ‘Iran‘ restricted to Yahoo! News:

And following for ‘Obama stimulus plan‘:

Currently, Dygest has two interfaces – (1) a search interface powered by yahoo boss and (2) a searchmonkey plugin. Its just a prototype so be kind and don’t be too judgmental.

[UPDATE] Try the search monkey app here

This is a follow-up post of The Monkey Just Got Delicious – I. The app is not yet public for the reasons mentioned in part I. As I had mentioned, my goal was to generate a tag cloud for the search results. Well, search monkey does not allow you to spit out arbitrary html, thus making it difficult to render a tag cloud. After much thought I settled for a color coded tag cloud (as in the screenshot below). You will notice the color of the tags gradually fading (darker shade means that the tag is more popular).

Got feedback, will listen.

[UPDATE] New tag cloud UI for deliciousify can be viewed here

[UPDATE] The search monkey app is currently disabled for public use as it was hitting the delicious rate limit. Hence it will remain as a prototype for now. BTW the delicious team is working on their own search monkey app and I bet its going to be much cooler.

I’m a big fan and an avid user of Yahoo! Search Monkey. So this weekend I decided to write myself a search monkey application that I have always wished for. Well, we all will agree that nothing beats human created metadata and what better metadata about search results can there be than the vast and rich knowledge stored in bookmarking services. My search monkey application deals with enriching the organic search results from Yahoo! with metadata from del.icio.us.

Sometimes the search summary does not provide a useful insight into the contents of the search result (as seen below). The only way users ascertain relevance is by clicking on the result and figuring it out themselves. Wouldn’t it be better if the contents of the result could be summarized by just a few words – keywords that highlight broadly what the document talks about. Deliciousify (as seen below) aims to solve this problem by listing the top tags about a search result from del.icio.us, along with its popularity (number of people who have bookmarked it). In the future, I plan to display a tag cloud for the results. Give it a try and send any comments/feedback my way.

Dancing with Matt

| August 4th, 2008

Matt Harding visited the Yahoo! campus a few weeks back where we had a chance to participate in the video below doing the signature Matt dance. A must watch – especially Jerry Yang (@ 1:26) and Filo’s cube. I’m the white speck at the end of the “Y” in the Y! formation.
