Preliminära resultat från våra studier kring humanoida sociala robotar på svenska i vården visar att det är viktigt för en del österbottningar att robotarna kan förstå dialektala uttryck och att robotarna talar finlandssvenska. Dessvärre finns varken finlandssvenskan eller dialekter med bland de språk som det satsas stort på globalt i utvecklingen av taligenkänningsalgoritmer. I projekten MäRI och TaFiDiAi jobbar vi med att inkludera finlandssvenskar i processen att ta med svenskan i automatiseringen och robotiseringen. I det här inlägget skriver vår kollega Leonardo Espinosa Leal vid Arcada att det är det enda rätta att ta med minoritetsspråken i utvecklingen av interaktiva digitala tjänster, och det redan från start.
Inclusion in Human-Robot interaction
Artificial intelligence has become the modern paradigm in almost all areas of knowledge. Significant advances in fields like deep neural networks (Goodfellow, 2016) have created algorithms able to rival humans in areas as never before, including vision (LeCun, 1995), language (Greff, 2016), and many others. Nowadays, machines are capable the defeating the human masters on almost any board game (Silver, 2018).
Performing tasks at the human level means that somehow humans can be replaced or repurposed in less repetitive tasks. Ignoring philosophical or sociological discussions about how this technological revolution can impact, positively or negatively, the human population in the near or far future in general, it is clear that one of the goals of these advances is the creation of fully autonomous and intelligent embodied agents.
The advances in robotics made by companies such as Boston Dynamics or SoftBank Robotics seem to bring the ancient dreams of creating artificial humanoids into reality. The secret source of these humanoid machines’ success is, apart from the advances in models, hardware, or software, done by highly skilled technical and theoretical experts, the endless homunculus amount of data generated by simple digital users.
Yes, you muggle! In most cases, the human’s digital footprint has been responsible for creating and tagging data (sometimes on purpose, in others as a side subproduct of our web surfing). Data that have helped train these human-level deep learning algorithms. And here is where the problem arises. Powerful tech companies have expanded their services and products created with inherited inequalities within that data.
The digital gap among different societies has allowed the creation of biased datasets. Modern estimations argue that more than half the global population has access to the internet; however, studies have shown that digital skills and access vary by region and gender. For instance, a 2019 study showed that 55% of men used the internet in the USA while only 48% of women did so. Moreover, only 44% of the population in the developing world and 20% of the people in the least developed world currently have internet access, in contrast to developed regions where over 85% of people have access. Similar inequalities can be found in other areas, such as age group, education level, and socioeconomic demographic information (Statista, 2019; Pew 2019).
The landmark moment in the history of deep learning is the ImageNet Large Scale Visual Recognition Challenge (ILSVRC) of 2012, won by Alex Krizhevsky (Krizhevsky, 2012). Here, GPU-powered Neural Networks enter the research sphere. ImageNet was an international contest where several research groups competed by bringing their best computer vision algorithms trying to reach the lowest classification error. ImageNet consists of 14,197,122 images organized into 21,841 subcategories. This dataset was compiled by Fei-Fei Li’s group at Stanford (Deng, 2009). This huge dataset has been the reference and the ground truth for new computer vision developments; however, it has been acknowledged recently that it contains flows and biases (Yang, 2020).
Other specific fields use a limited number of standard datasets, for instance, in Indoor Scene Recognition (MIT Indoor Scenes or Stanford 3D Indoor Scene Dataset); Face recognition (WIDER Face or IMDb-Face); Autonomous driving (Waymo Open Dataset or Virtual KITTI ). A quick inspection will tell us how western-urban-male-centric biased are these datasets. I encourage the reader to check the site https://paperswithcode.com/dataset, just filter by language to see how English is the dominant language by far, compared to the second in the list.
It is acknowledged that big tech players: GAMMAs (Google, Amazon, Meta (Facebook), Microsoft, Apple) or BATXs (Baidu, Alibaba, Tencent, and Xiaomi) are, with some academic institutions, the primary source of datasets for training artificial intelligence algorithms. These companies overlap in different digital markets and become active competitors in products and services in the digital world. A quick look at the origin of these giant digital behemoths shows implicitly that, in terms of language, English and Chinese are their main interests. Unfortunately, with its diversity of languages, Europe is lagging behind in developing technological products, exposing its citizens to a new linguistic cybercolonialism.
Natural Language Processing (NLP) is a subfield of linguistics, computer science, and artificial intelligence concerned with the interactions between computers and human language, in particular how to program computers to process and analyze large amounts of natural language data. The goal is a computer capable of “understanding” the contents of documents, including the contextual nuances of the language within them (Wikipedia, 2021). NLP is expected to become an essential player for improving the experience in Human-Robot Interaction (HRI). In the future, robotic assistants are expected to replace specific human labor or tasks. The success in the interaction between humans and robotic assistants is linked to the inclusion of populations not covered by products with technological limitations in language.
A local case
Finland is a small country in terms of population. Finnish is the primary language globally; only around 5.4 million Finnish-speaking natives are located mainly in the nordic areas (Kotus, 2021). Different academic institutions have made enormous efforts to develop several NLP products in the local Finnish language (Virtanen, 2019; Hämäläinen, 2021). The second official language of Finland is a regional variant of Swedish. Finland has approximately 296,000 Swedish speakers. Globally, about 9 million people speak Swedish as their first language (Kotus, 2021). Due to closeness with Sweden, the primary candidate for creating services are the tools developed using the Swedish language from Sweden (Malmsten, 2020). Although inside the Finnish Swedish community, there are identified four regions where the Finnish Swedish dialects are spoken (Ostrobothnia, the autonomous island province of Åland, Åboland, and Nyland (Uusimaa)), from these, there are ten identified dialects (Kotus, 2021a).
Development and study of Finnish Swedish population within Human-Robot Interaction real is a necessary step for developing more inclusive products and services. For instance, a successful campaign named donate your speech was launched in 2020, supported by the Finnish Broadcasting Company (YLE), to encourage Finnish speakers to create a large dataset for training speech recognition algorithms in Finnish (Donate, 2020). Similar initiatives funded by Svenska Kulturfonden have been launched recently, including the MäRI and TaFiDiaAI initiatives led by Arcada and Experience Lab that aim specifically to study and develop products for HRI within the Finnish Swedish speaking population in a Healthcare setup. TaFiDiaAI has been the first initiative for collecting specifically Finnish Swedish dialects (see http://snacka.fi/). More recently, Yle Svenska, supported by Svenska literature, has launched a similar initiative at a significant scale for collecting speech data (Donera, 2021)
These aforementioned initiatives are the first step for the inclusion of minorities within the Finnish society, there are a lot of challenges ahead, but digitalization and automatization are unavoidable; however, we agree that for an ethical and inclusive future, we need to take into account from the beginning, the creation of products and services that include all populations from scratch. In conjunction with the digital industries, researchers and academia must join synergies to build a more inclusive society where AI benefits all its citizens.
