Searching for images by colour

2 Comments

This is not a frequently asked question on my workshops but when it is raised by one of the participants it generates a great deal of interest amongst the rest. So far I have come across three that I would recommend trying.

The first is Exalead’s Chromatik, which is part of the Exalead Labs experimental area. This enables you to search a selection of Flickr images by colour and optionally by keyword. You first select one or more colours or hues from a palette which are added to a bar below the palette. You can adjust the proportions of  the colours in the photos by moving the separators between the colours in the bar. Luminosity can be toggled between bright and dark, and saturation between colourful and grey levels. The last option in the list is to search for specific images using keywords (I assume this searches the titles, tags and descriptions associated with the Flickr images). The implication is that once you have selected your colours you can then limit your search to particular objects. In practice, if you search for colour followed by keyword, Chromatik ignores your colour choices and searches only on your keywords. If, for example, you want to search for apples of a particular colour you must first search on apples and then pick your colours.

It pays to keep the number of colour choices to two or three, even if you require very specific colours, as this will give you a wider range of images to choose from. When the thumbnails are displayed you can hover over the best match and select “show images with same colors”. Click on an image and it is displayed full size, but in order to see further information about it you have to right click and select properties. This will give you a URL for the original image on Flickr but only for the image itself. It does not take you to the “full” Flickr page for the photo, which means that  you cannot check ownership and copyright.

The second tool is Multicolr Search Lab from Idée Inc. This uses “10 million of the most “interesting” Creative Commons images on Flickr”. As with Chromatik you select colours from a palette. You can select up to ten colours and click on the same colour several times if you wish to increase its prominence in the photo. Unfortunately there is no keyword search. On the plus side, if you find an image you like simply click on the image to go straight to its page on Flickr where you can double check the copyright situation.

And of course there is Google’s image search. Carry out a search on your keywords in Google images and above the results there is an option to select a colour. There are only twelve colours from which to choose and you can only select one but it works well enough. If you want to search only Creative Commons images then carry out the first stage of your search in the Advanced Image Search screen and select the appropriate option from the Usage Rights menu.

Brighton & Hove bus times on iPhone

3 Comments

Nice one Brighton & Hove, and I am not being sarcastic! According to the Local Government Chronicle Brighton & Hove City Council claims to have the first iPhone bus app. It has launched a free real time bus time information app created by one its residents, Rick Thompson, and which updates automatically to show live bus times across the area’s network.

My own local bus service, Reading Buses,  is just a couple of steps away. Most of our bus stops, even over “the river” in Caversham, have displays telling you when the next 2-3 buses are due to arrive so the data obviously exists. They just need to make that data available to someone like Rick.So how about it Reading Buses?

Google, Market Research, Statistics

Google compiles industry stats for the UK – sort of

Google has launched a new page that pulls together industry stats for the UK. Google – Internet Stats, which is biased towards information on electronic and online services and products, gathers data from third party vendors many of which are priced. A list is available at the bottom of the Internet Stats page. You can, though, submit your own “killer fact”.  All submissions are vetted by Google.

There are five categories: Technology, Macro Economic Trends, Media Landscape, Media Consumption and  Consumer Trends. Each section has further sub-categories.

This is not the answer to a market/industry researcher’s prayer. The number of statistics is very limited and the search option only searches within the browsable statistics on the landing page. Do not expect to be able to search for and find data on, for example, UK chocolate consumption! If your query falls within one of the listed categories you may be in luck.

Exactly where Google is going with this and why they have introduced it is not clear. This is a UK-only initiative at present and there is no link to it from either the .com or .co.uk main Google search pages. Neither is it listed in Google Labs. Even the official announcement on “Google Barometer: New! Internet Stats all in one place” gives very little further information.

Getty Images wins £2,000 over unauthorised web use of photo

If  nothing else, this is a good example of what can happen if you fail to check the rights associated with photographs and images found on the web, and then use them for your own commercial purposes. Some people refuse to accept that just because an image is on the web does not mean that you can do what you want with it. If you do not want to pay for an image, there are plenty of sources of public domain and Creative Commons images but even then there may be conditions and some restrictions on their use (see my posting Free-to-use images might not be).

In this particular case, a removals firm used a Getty photograph on their web site without paying for it. Getty found out about it because it uses tracking technology to detect the unauthorised use of pictures.

You have been warned!

gov.uk security stupidity nothing new

Those of you who have been following the comments to my earlier blog posting (Please Use Firefox 2 or IE 6) or my Twitter tweets might be interested in an item I wrote for my newsletter Tales from the Terminal Room, July 2002. Entitled “Inland Revenue’s Cookies Fail Crunch Test” – sorry about the awful pun – it suggests that gov.uk seems to have learned little about security over the last 7 years:

In the UK, it is that time of year when we suddenly realise that we have only a few weeks to complete our tax forms and deliver them to the Inland Revenue. I, says she rather smugly, have already done mine but not online as the UK government continually exhorts us to do. I did have a go last year but the Web site kept crashing and after four attempts I reverted to the good old-fashioned paper form. This year I did not even consider the online route, which is just as well because the service had to be temporarily withdrawn following a security breach.

A problem with cookies allowed users of Inland Revenue’s online self-assessment tax form to see other people’s tax details. An official statement explained: “The way in which the ‘session cookie’ identifying the user was managed meant that it could, in certain rare circumstances, be presented to another user.”

It seems that Inland Revenue’s site allocated the same cookie to more than one user because they were using IP addresses to identify users. Many Internet users, and especially those accessing the Internet from home, use ISPs with dynamic IP addressing: that is the ISP allocates a different IP address to a user each time they access the Net, which means that the same IP address may be assigned to several different users in quick succession.

The Inland Revenue said that examination of activity logs suggested that the web site had compromised the privacy of 47 of the site’s 28,679 users and there were 665 for whom the possibility could not be eliminated.

The problem has now been fixed and the site is back up and running, but I for one am not reassured.

For the Inland Revenue’s side of the story see: http://www.inlandrevenue.gov.uk/news/sa_online.htm

Inevitably, the URL in the final sentence no longer works but you can still view a copy at http://www.archive.org/.  Copy and paste the whole URL into the Waybackmachine Take Me Back box, and on the list of results click on August 2002.  Alternatively, http://web.archive.org/web/20020804140436/http://www.inlandrevenue.gov.uk/news/sa_online.htm should take you straight there.

Please use Firefox 2 or IE 6

This would normally fall into the “I don’t belieeeeve it” category had I not already heard of the problems endured by UK central and local government departments in trying to move on from Internet Explorer 6.

Out of curiosity I decided to see what pittance I might receive from the state when I retire so tried the advertised http://www.thepensionservice.gov.uk/. First of all I could not just use my existing username and password for the government gateway service to use the pension forecasting service. That’s fair enough. I appreciate the additional security level but then I had to wait two weeks for an activation code. This morning it arrived, I “activated” my account and attempted to log in. In a flash, a “Technical Error” page popped up with error and error ID codes, and instructions to phone them for help.

What followed has left me stunned.

“Are you using Firefox or Internet Explorer?” the nice lady asked.

“Firefox”

“Which version?”

“3.5.2” I replied

“If you want to use Firefox, you’ll have to go back to version 2”

A few seconds of silence followed and then I asked if I could use IE 8. No, was the answer, it had to be IE6 or possibly IE7. Google Chrome? Not compatible. Opera? She wasn’t sure but if it was the latest version then no. Safari? Er..probably not. She explained that they haven’t security tested the latest versions of the browsers and Chrome is definitely out.

It is pathetic, stupid and irresponsible. We are all exhorted to keep our browsers up to date as part of our online security measures but the UK government is encouraging us to do the opposite. We are encouraged to file our tax returns online and use the government web sites to obtain information about our entitlements, but to do so we have to use browsers from the stone age. It does not fill me with confidence. Quite the opposite, I am beginning to feel seriously paranoid regarding the security of gov.uk sites.

So have I got my pension forecast? Once I had stopped haranguing the poor lady on the help desk I was transferred to another department, my personal details were taken, and I was told my forecast would be in the post in about 10 days. So much for fast, efficient e-government!

I am still sitting here gobsmacked and wondering if I dreamed the whole thing. I think, after all, that this has to be filed as a Victor Meldrew moment.

Directionlessgov: compare Directgov search with a Google custom search

Checking through the last year of postings on my blog I regret to say that I somehow managed to forget to cover the excellent Directionlessgov. This is an “alternative” search option for the Direct.gov.uk web site and uses Google. It has has been set up by the group that is also behind They Work For You and The Government Says.

“We got so fed up with the general uselessness of the multi-million pound shambles otherwise known as the Direct.gov.uk portal, that we decided to build something better in under an hour. Sadly, we ran catastrophically behind schedule, but we still finished before lunch.”

Type in your search and view the results from Google on the right hand side of the screen. For comparison, and to rub salt and a hefty dose of chilli pepper into the wound, results from Directgov are displayed on the left hand side.

A search on my own council’s (Reading) recycling policies came up with the following results:

directionlessgov

No contest: Directionlessgov wins outright!

For another Google custom search engine covering local government, you might also like to try LGSearch, which I covered in March 2009.

Searching for file types made easy

1 Comment

One of the Top 10 Tips that participants of my advanced search workshops regularly come up with is using file format options to focus your search. If you are looking for an expert on a topic, a conference presentation or a quick overview of a topic then seek out PowerPoint files; government and industry reports are often stored as PDFs; and substantial collections of statistics may be left in Excel format. Both Google and Yahoo have options for file type searches on their advanced search screens, but if you want a quick and easy way of searching both of these search tools for the four main file types (Word, Excel, PDF, PowerPoint), then head for DocJax.

Simply type your search terms into the box and DocJax will pull up a list of all four file formats in Yahoo and Google that contain your terms. You can then limit your search to just one file type by clicking on one of the four logos at the top of the list.

DocJax

I have only one minor quibble with DocJax, which is that it does not deduplicate the results. Other than that, it is an excellent tool for filetype searching. Many thanks to Peter Guillaume for alerting me to the service.

If you prefer to search Yahoo and Google separately, then try Browsys Advanced Finder. Select Files form the menu at the top of the screen, enter your search terms and click on Yahoo or Google for your preferred file type. There is no need to re-enter your search terms for each search – just click your way through the list.

BrowsysFiles

I usually berate such services for not including Bing (formerly Microsoft Live Search) in their lists because Bing does sometimes come up with unique content. Although not included in Bing’s advanced search options one used to be able to simply incorporate the filetype: command followed by the file extension in the search. On testing it today, though, I discovered that the filetype command no longer works in Bing. Like the link and linkdomain commands, it has been obliterated from their search system. Another example of Bing dumbing down their search. This does not bode well for Yahoo: as part of the recent Microsoft deal, Microsoft will power Yahoo search and as a result Yahoo will lose many of its current search features. I’m afraid that rather than stealing market share from Google, Bing’s current approach to search will encourage users to stay with the big G.

Google Caffeine

2 Comments

A short post prompted by Phil Bradley’s posting on the proposed new hyperactive Google, nicknamed Google Caffeine. See his article for further details and background information, and if you are interested in comparing the current Google with Google Caffeine try Caffeine Compare. I have been running my searches and test searches on both over the past few days and found:

1. No difference at all for the majority of searches.

2. Minor and insignificant differences for a handful of searches

3. For some business information searches, worse and an increased number of irrelevant results with Google Caffeine.

Not much else to say other than I am not very impressed at this stage.
