Subject: Survey about the quality of alternate text
To: CHI-WEB at listserv.acm.org


I would like to invite you to participate in a survey about the quality of the alternate text for images in web pages and how semantic content analysis could improve it.

Alternate text is important for people with visual impairments to be able to comprehend what an image represents. It is made available via an attribute to the <img> tag in web pages and is used by assistive technology to describe the image for those that cannot perceive it visually. It is the most common example in the field of web accessibility. Having an alternate text attribute does not immediately guarantee the image is accessible. The content of the alternate must properly describe the image. With this survey we wish to characterize how well current alternate text accomplish this and how semantic analysis can assist in improving the quality of alternate texts.

The survey is anonymous and should take less than 15 minutes to complete. Use the following link to participate:


Thank you for your help!

Kind regards,
Carlos Duarte
