Calling All Perl Hackers

Lokku Limited (proud owners of Nestoria) are now recruiting a perl programmer. This is very much a startup environment (7 employees, 4 engineers, one room) where employees are expected to wear several fashionable hats and contribute to decisions across the business.

General experience with OO perl and internet development is more important than specific exposure to a set of acronyms or libraries, but time spent with LAMP, AJAX, and Mason are definite bonuses for this particular role. We are looking for a full time hire to work out of our offices in Covent Garden. No contractors or telecommuters, please.

The full job posting is available on the Lokku site.

Please send CVs to jobs >at< lokku.com.

A Note on Data Quality

Ahoy,

in our recent post about our new co-branded search tool for webmasters there was an interesting discussion afterwards about data quality of some of our data sources.

First of all, it’s great to see everyone getting so excited about this topic, it’s one we feel passionate about ourselves. As loyal readers of this blog will know, data quality is a major issue here at Nestoria. Here’s a post from just last week about how we’re extracting more information for property searchers from listings as a way to improve data quality.

We take it so seriously that we currently exclude 15-20% of the listings we have because they are of low quality, and we’re constantly fine tuning our algorithms to catch more dodgy listings. Unfortunately spam rel=”nofollow” is a very real problem in the classifieds industry.

As anyone who’s ever worked with software (or had an email inbox) can imagine, catching this isn’t a simple. It’s a very iterative process.

We’ve recently integrated a few new data sources, and it looks like a few bad listings slipped through.

As an example, this morning we’ve spotted this gem:

bad listing

(no offense Michelle, it’s nothing personal, it’s just that people come to Nestoria to look at houses, not blondes).

So, loyal readers, we can say we’re hard at work on it (you should see some of the stuff we throw away. It makes viagra ads seem tame). Keep the passion for quality! We welcome all ideas you have on the topic. Please get in touch via our feedback form.

Nestoria for your website - co-branded property search

Since we expanded to cover the whole of the UK a few months ago we’ve had great feedback from the online property community (not to mention great growth in number of users).

We’ve also had more than a few requests from webmasters asking how they can have adopt some of the features of the Nestoria property search. As avid readers of the blog will know, we’re always on the lookout for ways to provide tools for webmasters, and these requests got us thinking.

Today, we’re pleased to present the result: a free, easy to install co-branded Nestoria search that allows any webmaster to offer his or her users a best of breed property search experience.

What are the main benefits of the Nestoria co-branded property search?

  • It’s yours! You can customise the look and feel to fit your user experience
  • It’s good! Your users get the same great relevancy, user experience and comprehensiveness that we offer on Nestoria itself.
  • It’s simple We’ve done our best to make it as easy as possible to set up.
  • It’s free!

We’re delighted to announce that the first implementation is already live on one of the UK’s leading property blogs: theRatandMouse.

Interested? Then dive in to the details, or check out our demo example.

As always, please let us know what you think.

Simple, sugary search tools

At Nestoria, we’re all about people finding their dream property.

We like to provide you, our users, with a variety of simple, easy ways to do that.

The most recent example of this can be seen on sugarcodes.com. Sugarcodes let you search or access a variety of resources by entering a ’sugarcode’ and then what you’re searching for.

So, for example, you could type:

g falmouth

into the search box on the sugarcodes homepage. This would search google (that’s the g bit) for all information on falmouth (the falmouth bit).

We have added two codes ourselves:

nest (search Nestoria for property to buy)

nestr (search Nestoria for property to rent)

So, to search for property to buy in Chelsea, you would type:

nest chelsea

Give it a try, or read more on sugarcodes!
Please remember, we’re here to help you! So if you would like to search any other way, feedback to us!

Looking for a loft with wooden floors and high ceilings?

Greetings Nestoria fans!

You’ll be happy to know we’ve been hard at work on enhancing our property listings to provide you with a faster and simpler property search experience. In the past we’ve used our Natural Language Processing (NLP) skills to document some of the peculiarities of estate agent speak, but we’ve also been applying these skills to improve the quality of our listings.

Over the last few days we’ve rolled out some subtle improvements to the way we display listings. As a few examples of many, at a glance you can now see if a house or flat

is a loft:

Loft screenshot

has a wooden floor:

Wood floor screenshot

is an ex-local authority property:

is a mews house:

or even if the property has a sauna:

mews house screenshot

Of course these are just a few of many, we also show if a house has high ceilings, has a hot tub, is grade II listed, and many more. We know many of you want the ability to search by these attributes, and you can rest assured we’re working on it.

Please let us know if there are other bits of information you’d like us to extract from the listing descriptions. We’re only a short feedback form away.

Open Source Mapping roundup

A quick overview of what is happening in the open source mapping world:

We recently interviewed Ed Parsons on this blog.

It was a while ago but OpenStreetMap now have permission to use the Yahoo aerial imagery to plot roads onto - see their entry on it. This will prove particularly useful in cities, where the imagery tends to be good and GPS reception tends to be bad.

Steve Coast (from opengeodata.org) has reached day 16 of his ‘Month of OSM’. This is an interesting approach to funding open source projects where Steve worked out what he would need financially to support his working on OpenStreetMap for a month. He put out a request for this amount to the community and it was raised pretty quickly. If you sponsored him and want to check that he is working you can use the ‘Stevecam’ (if he is not working you get some tasteful curtains instead).

This weekend (27-28 Jan 2007) OpenStreetMap are having a mapping party in Central London. If you are around and want to help please do, no GPS required (due in part to the Yahoo imagery).

Nestoria adds support for OpenSearch

As regular readers of this blog know, we’re always trying to find ways to make it easier for people to search for UK property. So it was only natural that we’ve now added support for the OpenSearch standard to Nestoria.

What is OpenSearch?

OpenSearch is a standard for search results. Learn more about the technical details at Wikipedia.

What are the benefits of OpenSearch for the average Nestoria user?

If you use a browser that supports OpenSearch - like Firefox 2.0 or MSIE 7, which our tools show that 40% (and growing fast) of Nestoria searchers use - your browser will “automagically” detect the fact that Nestoria is OpenSearch compliant and allow you to add Nestoria as one of your default search engines. This means you can search Nestoria directly from your browser, thus finding highly relevant properties even more quickly.

How does it work?

It’s simple. Surf with an OpenSearch compliant browser to Nestoria’s homepage, the browser will automatically detect that Nestoria supports the OpenSearch standard and will display a way for you to add the search engine to your default search engines. In Firefox 2.0 a small magnifying glass will appear in the search box in the upper right. IE7 adds a yellow arrow to the search box. Simply click on the magnifying glass, and you can then select Nestoria and add it to your default search engines. Hope this doesn’t sound complicated, it’s actually not too tricky.

Please add Nestoria to your default search engines, and happy searching.

This is just one of many of the tools we offer for UK property searchers, webmasters, and developers. We’re always looking for more ways to make it simple to find UK property. We have a few ideas (you can expect a few more announcements in the coming days), but of course we’re always grateful for your feedback.

Where will you be one month from now?

There’s a chance that if you’re moving to London, you could be looking at a property in the soon-to-be-extended congestion charging zone.

Almost four years after the congestion charge’s introduction, it is due to be extended towards Kensington and Chelsea, one month from now (19th February).
Why is this being talked about on our blog? Well, we thought that our users might like to know if the property they’re looking at falls within the congestion charging zone. So, since the launch of our website, we’ve been doing showing searchers exaxtly that. We even identify those properties which fall into the extended charging zone.
What to look for:
On the property search results page, look for the red congestion charging logo:

Congestion charging logo

This can be seen under the brief property description and indicates that a particular property is within the congestion charging zone, or soon will be:

Congestion charging logo under property descripton
For example, look at results for a property in Kensington.

We hope this goes some way to helping you, our valued users, find your perfect pad in or out of the congestion charging zone.

Property Lists in Action

A few months ago we announced the launch of our Property List tool for webmasters. Property lists are an easy and free tool that allows you to add listing to your website.

The lists are totally customisable, allowing any webmaster to set color, font, font-size, number of listings and to turn pictures on or off. We've tried to make it as easy as possible to adapt the listings to your look and feel. Installing the lists is as easy as cut and paste. 

Today we thought we'd highlight a few of the sites that have adapted our listings to provide a relevant offer to their readers.

For example, take a peek at www.lordshiplane.co.uk, a site about Lordship Lane in East Dulwich, using the property list in their right margin.

Or visit WirralWide.com a local portal for the Wirral area that has integrated the property lists in their property overview:

 

Wirral Wide

 

These are just two examples of many. We'd especially like to thank everyone who's sent us feedback to help make our tools more useful for webmasters and more relevant for users. Of course, if property lists aren't your cup of tea, perhaps you'd be interested in one of our other tools for webmasters, or even trying your hand at building your own via our API.

We've got several more announcements about additional ways for people to search Nestoria and for webmasters to add Nestoria's property search functionality to their sites coming soon. Watch this space!

Nestoria Interview - Ed Parsons - UK Geo Expert

As part of our ongoing series of interviews with thought leaders in our space, today we interview Ed Parsons, a highly regarded member of the UK geography community. A fellow of the Royal Geographical Society, Ed was until recently the CTO of the Ordnance Survey. Prior to that he has a deep background in GIS (Geographic Information Systems), both commercially and in the academic world. Ed's blog is at edparsons.com

1. The last two years have seen an amazing amount of innovation in the online geography space. Which developments have you found to be the most interesting, the most innovative, and which do you think will have the most impact on society as a whole?

Yes the last two years have been the most exciting I can remember in the digital geography space, the massive surge of innovation has been a result of the opening up of geographical information which had until then been locked up behind expensive GIS systems or was beyond the scope of individual use. Two unrelated developments have opened up geographical information, the development of rich mapping API's and the growth of community developed datasets. 

The Mapping API's interestingly are the combination of new technology in the form of AJAX libraries and perhaps more importantly advertising based business models which allowed the likes of Google and to a lesser extent Microsoft to fund the licensing of massive amounts of commercial geodata, which they can then make available "Free" at the point of use to developers and users.

Technology has also really driven the development of community based geodata projects like OpenStreetMap and Geograph.co.uk , now almost anyone with a laptop/pda and a cheap GPS can capture fit for purpose geographical information. In many ways the Geographical Information market was a perfect one to really make the most of what is now known as the Web 2.0 philosophy, inverting the traditional top down approach to information provision, with technology now making the citizen central in both the use and creation of geographical information - This is a massive shift in the industry and the more traditional content providers are trying their best to ignore this - at their peril !

2. The UK seems to have a wealth of geo-related online communities like Geograph.org.uk, OpenStreetMap, New Popular Edition Maps, and Free the Postcode. What do you think of these efforts?

It's great to see so much coming from the UK community, but we have to recognise that many of these efforts exist because of the very particular nature of the UK geodata market. Although the UK is by far the best mapped country in the world, because of the licensing regime Ordnance Survey and the Royal Map operates under, it is very difficult for individuals to get access to even relatively small scale data, as a result efforts like OpenStreetMap (OSM) and Free the Postcode are filling a market need. 

I have always personally been very supportive of these "Open Source" mapping projects and they are offering the user more choice in the market, and just as with software both open and closed source will coexist in the market for the foreseeable future. While at the OS I often suggested that some of its small scale data products could be made open source perhaps to contribute to projects like OSM, but as a organisation it was not ready to make such a step, I'm sure however in the future National Mapping Agencies will embrace Open Source.

3. What are your predictions for online geography in the UK in 2007? 

I don't think we have yet seen the full impact of a networked global market on information businesses, by this I mean access to huge numbers of computer operators in India and China who can create and process geographical datasets that previously were not economically viable. For example organisations have in the past invested in computer algorithms to automatically identify features such as buildings from aerial imagery, these have met with limited success. I expect this year we will begin to see datasets captured from image or out of copyright map sources using offshore operators starting to become available.We will also see continued embedding of geographical data in online applications, hopefully increasingly been used as a source of context, sorting information using proximity as a filter term. Hopefully we will also begin to see the "walled gardens" of the mobile network operators beginning to break down allowing more innovative local based services on mobile devices.

4. What are your thoughts on the developments in the property search sector in the last year?

I must admit to not watching the property search sector particularly closely however, it would appear that vertical search sites like Nestoria and other aggregators are beginning to move beyond the online shop window approach. After-all finding a property for many people is actually a geographical problem, with constraints to do with proximity to schools, public transport etc. equally important as number of bathrooms and price!

5. What are the challenges you think a vertical search engine for property like Nestoria faces?

Visibility and awareness. both in terms of vertical search generally, i.e. some sites are actually better than Google for specific information !! , and then within the vertical itself. Was is interesting is that in 2007 the traditional marketing approaches are not necessarily the best approach, after-all when was the last time you saw a myspace advertisement !! 

Many thanks Ed for offering us your thoughts. We agree vertical search engines are often better than general web search for finding specific types of information. Here at Nestoria we'll do our best in the coming year to find innovative ways to raise our visibility and to find chances to work together with the UK's community of geographic innovators.
