I started a personal project a while back...Working on African languages, I meet people from all over the continent. I found it very interesting how similar we can be on some things and how drastically different we are on others. So I decided to read one book from each African country...🧵

i’m looking to recruit a postdoc to work on this (documentation + evaluation on accuracy, reliability and societal impacts). hope to advertise detailed descriptions of the role in the coming weeks

Dr Abeba Birhane@abeba.blacksky.app

anyone working on documentation (compiling some kind of inventory database) of use of llms within government bodies and for public service use, particularly in europe?

Book #12 How Dare the Sun Rise? By Sandra Uwiringiyimana from the DRC This was a heavy one...I had to sit for a while with the first few chapters as Sandra recounted her experience of loss and greif...

There is so much about navigating the Internet in a low resourced language that makes one unnecessarily vulnerable to malicious actors. It's not just a quality of experience difference, but literally the soft belly through which misinformation spreaders attack.

Very excited for our upcoming #AIES paper Into the Void: Understanding Online Health Information in Low-Web Data Languages. Link: arxiv.org/pdf/2509.20245 1/n

While social media platforms are increasingly being used as sources of information for critical sectors like healthcare, the quality and quantity of information available is not always guaranteed, especially for languages with limited data available online. 2/n

We investigate online health information on #YouTube and #TikTok in two low-web data languages, Amharic and Tigrinya. We find that linguistic, technological, and socio-cultural constraints on information access and production lead to degraded information quality for low-web data languages. 3/n

Book #11 Missing in action and presumed Dead by Rashidah Ismaili from Benin Got this from Thrift Books and by luck got a version with the author signature ☺️ Its a beautiful collection of poems and my fav one is Nomad attached in the picture below

Lol here is an example: A google translated Tigrinya article: ti.wikipedia.org/wiki/%E1%88%... English version: en.wikipedia.org/wiki/Wedding... I took the part that says "Ethiopia" from the English article and ran it through Google Translate...almost identical output save a few words.

This is a good step IMO...but i think we conflate "Wikipedia" with "English Wikipedia" and "AI Generated" with "LLM generated" We should also be having conversations on Machine Translated text in non-English Wikipedia...those are also "AI Generated"😐

Wikipedia's policy for handling AI-generated articles could be "an important example for how to deal with the growing AI slop problem from a platform that has so far managed to withstand various forms of enshittification that have plagued the rest of the internet." www.404media.co/wikipedia-ed...

Book #10 In the company of Men by Veronique Tadjo of Cote d'Ivoire. A moving story of how Ebola ravaged communities told through different perspectives in each chapter. My fav chapter is when the story is narrated by the Baobab tree. Also touchs on economic politics of healthcare services.

Watching this lecture by Dr. Fasil and Dr. Egid..I have not finished it but thought i would share the link for anyone interested...my main point of interest so far is in difficulty of translating philosophical terms and the role of language in philosophical thought www.youtube.com/live/JwXrGEC...

Book #9 Dead Aid by Dambisa Moyo from Zambia My first thought is "intriguing." Details how aid harms African communities. However, I think there is little proposed as a practical recourse and that some of the depictions oversimplified the reality.

Book #8 Memoirs of an Arabian Princess from Zanzibar by Emily Ruete Similar to the memoir I read from Leila Abouzeid of Morocco in a lot of ways. There were some difficult and at times painful parts to read, especially as it relates to Blackness and the experiences of Tanzanians and Ethiopians.

Book #7 Infidel by Ayaan Hirsi Ali from Somalia I don't think I can summarize my thoughts about this in a Bluesky post coz i have a lot of negative thoughts😅 so i am not going to attempt. Let's just say it was book #7 and leave it at that.

Book #6 Unbowed by Wangari Maathai from Kenya A rec from @abeba.bsky.social ❤ One of the most powerful memoirs i have read. Many small similarities with growing up in Ethiopia, like being told being out in the rain will make you "grow", the central place fig trees have in the community...

Book #5 Unsung Giants Who Fought to Keep Africa Free by Okoth Owity Dpap from South Sudan The author uses linguistic evidence for claims about the lineage of his people. How the /ɲ/ sound was removed from many words and that made it difficult to make connections.

Book #4 Americanah by Chimamanda Ngozi Adichie This one i am sneaking in even though i read it years ago (if you know you know) There was a part that stuck with me...when power goes out in the city and comes back, the whole neighborhood cheers. And we do the exact same thing in Addis 😁

Book #3 Return to Childhood by Leila Abouzeid from Morocco This was interesting in that it was a translation from Arabic and as someone who speaks a bit of Arabic, i could tell small features of the language being reflected :-) Also gave me a glimps into experience of Blackness in Morocco.

zero-shot ASR is difficult due to many reasons; one being that languages use different writing scripts! Prior works handle this through the use of IPA. In this work, we: 1. Propose using transliteration as a means of zero-shot transfer 2. Select transfer languages based on shared phonetic coverage

We experiment with using English and Arabic as transfer languages and Amharic and Tigrinya as target languages. We find: 1. Pre-trained models have very limited learned knowledge in low-resourced languages. Zero-shot performance was less than 6% accurate for both target languages.

KG completion requires structured data that is not readily available for low-resourced languages. We propose: 1. Reformulating KG completion as a QA task 2. Training a retriever to fetch context from unlabeled data 3. Training a generator model to predict the tail given the question and context.

Book #1 is Decolonization and Afro-Feminism by Professor Sylvia Tamale. Was introduced to this book by a long thread on the other platform back in the day by @abeba.bsky.social :-) It has really informed a lot of my research, I even quote it in one of my papers:

Book #2 is "No Sweetness Here and Other Stories" by Ama Ata Aidoo from Ghana. Fav quote: "But my son, why must you travel that far just to cut grass? Is there not enough of it around here?", a father's response to a son who wants to go abroad to earn more money.

A few notes: 1. I am trying to read with a strong preference for women authors. 2. I try to buy the books used at local bookstores or directly from the authors. (it is extremely hard to find books by African authors, let alone female African authors!)

Starting this project reminded me of one of my fav books by an Ethiopian author about the author's backpacking journey from South Africa to Egypt I just finished book #10 and decided to start posting about the books I am reading...not sure what I will post, maybe quotes, summaries, or reflections..
