Title: Finding company logos through their websites: A multimodal approach
Examiner: Flavius Gruian
Supervisors: Marcus Klang (LTH), Frank Camara (AFRY Group AB)

Retrieving information about a company from their website is possible through web-scraping. A good example of this is the logo which has several use-cases. The obstacle however is finding which of all the images is the requested logo. This thesis presents different models for classifying if a web-scaped image is the specified company's logo. These models vary from trivial, machine learning text and image classifiers to multimodal solutions. Each model is trained on a diverse data set with companies and websites. They are thereafter evaluated and compared using several classification scores. Text classification models showed viability in selecting company logos, while image methods had problems with context and filtering out other logos from other companies or brands. Multimodal methods showed high potiential and using a weight-based decision-model performed better than any other method, with an MCC of 0.7042. This indicates multimodality is an encouraging approach to finding company logos.
