Over the past few months, [Melvin Wevers](/person/melvin-wevers "Melvin Wevers") joined the KB Lab as Researcher-in-residence. During his stay, he did not only manage to [defend his PhD ](/news/interview-researcher-residence-melvin-wevers-nwonl "Interview with researcher-in-residence Melvin Wevers at NWO.nl")succesfully, but together with [Juliette Lonij](/person/juliette-lonij "Juliette Lonij"), he worked on a [research project ](http://blog.kbresearch.nl/2016/10/03/our-researchers-in-residence-2017-will-be/)focusing on finding trends in newspaper advertisements using computer vision methods.

This work has now been concluded and a wonderful advertisement browsing tool using an underlying dataset of almost 430.000 advertisements are available for research. Melvin describes the process of the project and how to use the tool in his blog post. We would thus like to invite you to have a look at the blog, try the tool and let us know if you would like to also use the data.

**Dataset:** [SIAMESET](/dataset/siameset "SIAMESET")

*The SIAMESET dataset was created by Melvin Wevers and Juliette Lonij for the tool [SIAMESE](/tool/siamese "SIAMESE"). The dataset consists of images and metadata of advertisements from two Dutch national newspapers: Algemeen Handelsblad (1945-1969) and NRC Handelsblad (1970-1994).* [Continue reading and access the set...](/dataset/siameset "SIAMESET")
