Common placename misspellings

Fellow Nestorpeople,

we thought we’d revisit a topic we first discussed some time ago: placename misspellings. Today we thought we’d list some of the trends we see in how some property searchers mangle place names.

First a note on how we deal with place names we can’t recognise. We do our best to ‘auto correct’ common misspellings, of which there are two types: typos and just plain bad spelling. Typos typically happen because someone mistakenly hits the wrong key on his keyboard, while bad spelling is simply because they simply don’t know how to correctly spell a placename. As an example you’ll see that if you search for aproperty in Noting Hill (note: one t, not two) or aproperty in Botting Hill (B is next to N on a keyboard), in both cases you are redirected to properties in Notting Hill. In each case the user just magically lands on the page he ‘meant’ not the page he actually typed. Like all technology our algorithms aren’t perfect, so let us know f you find examples of our auto-correction not working as you would hope.

Now on to some of the common problems we see from UK property searchers:

  • Adding ‘E’. Examples: “Bridgenorth” instead of Bridgnorth or “Edgeware” instead of Edgeware.
  • Dropping ‘E’. Example “Folkstone” instead of Folkestone.
  • Double ‘H’. Examples: “Southhampton” instead of Southampton.
  • mixing ‘LE’ and ‘EL’. Examples: “Wimbeldon” instead of Wimbledon.
  • Phonetic confusion. Examples: “Wry” instead of the correct Rye, “Fullham” instead of Fulham or “Isle of White” rather than Isle of Wight.
  • Bad spacing. Example: “New Castle” instead of Newcastle.
  • I’ll make no attempt to discuss place names in Wales. All rules are out the window.
  • and finally, our old favourite; no one can spell Marylebone.

On the topic of odd placenames, we leave you with one interesting thought: who knew there are two Hollywoods in the UK?

Happy spelling.

Grappling with too many results

My fellow Nestorticulturalists,

good news, we recently rolled out some minor design tweaks in the hopes of making it a bit easier to sift through our database and find your dream home more quickly.

Specifically, we’re attempting to grapple with the situation when you search across large areas like London or Scotland where we typically have more than 50,000 homes. In these cases it’s difficult to argue that there is a relevant correct search result. While we do show a few houses or flats we focus on helping the user quickly narrow his search to a more manageable number of possibilities. We’ve tried to make this as clear as possible.

Have a look and please let us know what you think. Here’s a screenshot of properties in Wales:

Welsh regions

The problem isn’t just one we face in large geographies - we have it everywhere we have a density of listings - for example as seen here when you search for a home in East London

East London

As always, best of luck with your house hunt. Rest assured our work on usability is far from over, we have a few more design changes being tested right now on a subset of users. More soon.

More photos anyone?

Greetings Nestormaniacs,

Today we rolled out a tiny new feature to make your property searching even easier. In cases where we know it we now let you know if a listing has more photos than just the one we’re showing. See an example in this screen shot:

screenshot of more photos text

It’s all part of our never ending quest to bring you the most relevant search results. As with every tweak to the site, we’re keen to know what you think. Happy house hunting!

Ariadne Capital - ‘Looking for the future of search’

Fellow Nestordelphians,

Just a quick note, tomorrow I’ll be a member of a panel discussing “the future of search” at Ariande Capital’s 2nd Investor Forum. The lineup looks great. The discussion will focus on vertical search engines versus generalists, the tie in between mobile and search, innovation, and the integration of search with social networks. All worthy topics that should generate some interesting (and passionate) points of view. There will also be separate panels on digital music and mobile content.

If you’re in the audience please do say hello. I would love to hear all suggestions about what we could do better at Nestoria.

Nestoria Rank update - December 2007

Fellow Nestorwegians,

The time between Christmas and the New Year is a natural chance to look back on the last year and what we’ve accomplished. The next few days we’ll do a few more reflective posts summarising some of the accomplishment of the past year.

First up we thought we’d revisit Nestoria Rank, the algorithm we use to try to present relevant results to property searchers. Over the last few months we’ve continually experimented with changes designed to get people to the right house or flat more quickly.

Some of these changes have been very visible, others are more related to the algorithm itself. Let’s go through some of the more visible improvements first:

We now allow you to search by property characteristics.

This means searches like: an unfurnished two bed flat to rent near Little Venice with a balcony are now easily possible (right now we have 111 of them in the database)

Likewise, we’ve added the ability to filter your search only for “new builds”

We know newness to the market, or ‘freshness’ as we call it is a critical part of how people search for their next home so we now show you how long a property has been on the market and allow you to sort properties by age.

We’ve also integrated more and more local content to provide context to your property search. Most recently we’ve updated the London tube lines to add the London Overground, but we also added sports facilities and parking spaces in the last few months.

But those are just some of the new features you as a user can see. Rest assured we’ve been equally hard at work optimising the backend systems that you don’t see. Over the last few months we’ve been experimenting with systems that learn from individual user behaviour and adapt in real time. This is still in test mode, but we’re almost there. So don’t be surprised if the guy sitting next to you in the office starts getting Nestoria different search results than you.

Our thanks go out to everyone for the feedback we get on new features, but especially we’d like to thank those folks who volunteered to be betatesters.

So, what does 2008 hold? Well in the immediate future you can expect better integration of the metadata we recently made available via our API, and we’re always playing with data visualisation.

BTW - If you don’t like the way we’re displaying search results you have two choices: please let us know what we could do better and we’ll try to run a test with your suggested modification, or you can try your hand at our API and build your own interface. In the last month there have been many interesting uses of the API.

Search by property characteristics live

Greetings Nestorlonians!

We’ve just launched a new property search functionality in test mode. Some Nestoria users will now begin seeing a slightly different layout that gives you access to a new feature: ability to search by property characteristics. For example you can now search for a flat in Putney with a garden - or Grade II property in North Shropshire. Ok, that’s cool. But that’s not all - you can also select characteristics of a property that you don’t want to have. For example maybe you want to rent a flat in Maida Vale that’s not ‘lower ground floor’ and not an ex-council flat. No problem, search away. We offer lots of other common features that you can either include or exclude from your search. Things like ‘parking’, ‘high ceilings’, ‘furnished or unfurnished’, ‘freehold or leasehold’, ‘basement’ and more.

One challenge we’ve grappled with in rolling out this new feature is how to present so many options while still maintaining the simplicity and cleanness that we know you love. We’re not sure we’ve found the optimal solution, but here’s what we’ve come up with:

By default most of the search options are hidden away:

By clicking on the ‘more search options’ link on the right above the map a menu opens giving you easy access to more complex filters:

We’ve been testing various versions of this functionality for the past few weeks, and we’re excited to finally get it out. For those of you in the random test, please let us know what you think. For the others please have a bit of patience - we’ll gather feedback, make improvements, and then roll this feature out to everyone.

Big thanks to two groups of people: our diligent beta testers who provided great feedback, and the hard working code slingers behind the Yahoo! User Interface library and the ydn-javascript support list.

More beta tests coming soon! Enjoy the weekend.

The challenge of ambiguity

Fellow Nestorese,

as is our habit we often like to give you a peek behind the curtain of a vertical search engine and show you some of the challenges we face. Today I thought I’d explain the difficulty of ambiguity.

We humans have fallen into the lazy habit of using the same word to mean many things, including place names. A shockingly high number of places in the UK share the same name. For locals this is typically no problem, because it’s clear which place is being referred to, but it can make the lives of a property search engine developer struggling night and day to help you find homes to buy and rent as easily as possible very difficult. For example, if you just search for a properties for sale in Rushton how do we know which of the three Rushtons in the UK you mean?

Rushton

But of course there are some placenames, that, though they exist in multiple locations around the country, have a clear winner. For example, properties for sale in Waterloo. In a flurry of post Napoleonic war celebration, many areas were named after the historic battle ground. There are five Waterloos around the UK, but when most people say they want to rent a flat near Waterloo, they mean near the south London train station. In those cases we take you, our dear flat searching friend, directly to what we believe is the dominant result, but also give you the option to change your search to the more obscure locations:

Waterloo

Differentiating between the locations which are truly ‘ambiguous’ and those like Waterloo where there is a clear winner is the challenge. These are the subtle tweaks that lead to a product that ‘just works’. Please let us know if you’ve found any locations you think we’re not quite getting right.

One final note, this problem is in no way isolated to the English language. In fact the UK isn’t bad - I’ll leave it to our spanish blog to rant about how many San Sebastians there are in Spain.

The weird and wonderful world of search

Today we present a bit of Friday fun.

Like many websites, we closely monitor which terms and queries people are using in general web search engines like Google, Yahoo! and MSN to reach Nestoria. Typically these queries are quite standard - for example “homes for sale near Stoke on Trent”. But sometimes we do see some odd and interesting surprises. We thought we’d share a few with you today:

  • “why would people move to falconwood?” We say, why not? Falconwood is a nice place to live near Eltham, South East London. We at Nestoria are particularly fond of the Eltham Palace, an amazing residence of Stephen and Virginia Courtauld from the 1930’s. Are you in the market for something nearby? You may start your search by considering Eltham houses to buy.
  • “how to find a decent property to rent in london” This is a tough question for a search engine to answer. It’s very hard to know what is meant by ‘decent’. Perhaps a three bedroom flat in a not outrageously expensive area of London like Fulham, or a house in one of the commuter paradises like Harpenden?
  • “houses for sale 5,000″If ever there was a challenge to offer relevant results to our users, this is one. Can “any” property search engine in the UK find houses for sale for less than five thousand sterling? We try our best, but there are limits. We do however have hundreds of thousands of houses for sale across the UK.

In general we find that our users set the bar very high indeed. A recent Nestoria user searching for “houses for sale in chelsea” ended up filtering down to properties in Chelsea for not more than 125,000. And we found one for him (or her), only it was a garage. Our technology may seem like magic, but not even we can accomplish the impossible task of finding a cheap home in Chelsea.

Have a good weekend.

Sliding fun comes to Nestoria

Nestoria fans, once again we take a step forward on the long path of making your search for homes to buy and rent in the UK as simple as possible. Today we rolled out ’sliders’ or filters that make it simple to refine your property search.

Let’s say for example you want to find a 1 bedroom in Stoke Newington between £175 and £225 a week as pictured here:

sliders screenshot

Well, no worries, just search for property to rent in Stoke Newington and a few quick slips of the mouse later your filters are set, you press “Refine Your Search” and you’re presented with a tasty array of relevant and fresh flats just waiting for you to move in. Next thing you know, you’re calling your friends and distant acquaintances begging them to help you drag your old couch down four flights of stairs into your new luxury Stoke Newington abode. It’s that easy.

Some technical notes: First of all, big thanks to the gang over at MooTools for making this so easy. We dropped their library in and it worked like a charm right away. We can’t recommend it enough. The label says MooTools is a compact, modular, Object-Oriented javascript framework designed to make writing extensible and compatible code easier and faster, and they delivered on that promise.

Secondly, though we have made every effort to test this new feature across a wide variety of browsers and platforms, do please let us know if you have any issues.

Okay, enough blog reading, go start sliding.

Sharing is good, especially for data quality

Last week we launched a minor tweak to our algorithms which we think should improve the quality of the user experience fairly significantly. Flatshares are now sorted into their own category (like property to buy and rent) and are no longer included in the main index. Here’s an example of flatshares in Docklands

screenshot

Searching for flatshares and flats to rent or let really are different experiences. This change removes the flatshares from the main index which should lead to a cleaner search experience for everyone. If you want flatshares, they’re there for the clicking, but by default you no longer get them clogging up your rental search.

This change was prompted by some of the feedback we’ve had both from users directly and on blogs. Many thanks for everyone who takes the time to comment and help us get better. Don’t let your opinion go unknown, let us know what you think.

So there you have it, another small step closer to the perfect property search experience.
