Against a background of traditional views of women, rising internet use, a young population and an unsafe offline life, women and girls in Ethiopia are facing increasing amounts of digital violence. Some women, feeling endangered, have left the country as a result. Researchers, activists and lawyers have called for online content to be taken down and specific digital legislation to be drafted and enforced. == Online violence and its offline effects == Sexual violence against women and girls in Ethiopia is common. In 2023, in the Women, Peace and Security Index by Georgetown University, Ethiopia came 146 out of 177 countries. Over several years online harassment of and violence against women and girls in Ethiopia has increased. It can range from sexist remarks about appearance and women’s role in society, to revenge porn, threats of beating, acid attacks, abduction, rape or death. The real-life effect on women and girls of these attacks can include mental health problems, damaged reputations and a withdrawal from public and economic life. When the online attacks migrate to the real world, for example when online attackers find out where the targeted women and girls live, this can result in physical attacks, street harassment, threats to children and can cause victims to move house or job or even flee the country in fear of femicide. In a country that criminalises homosexuality, it can also lead to physical attacks on LGBTQI+ people in particular and indeed on anybody labelled as homosexual. == Research studies == The Centre for Information Resilience (CIR) conducted interviews with Ethiopian women holding public roles or being active online. The centre published a report on this in 2024 entitled ‘Silenced, Shamed and Threatened’. They found that technology-facilitated gender-based violence (TFGBV) had become “normalised to the point of invisibility.” In 2024, CER also published an analysis of gendered hate speech on social media in Ethiopia called ‘Normalised and invisible.’ It is thought that traditional views of women, the young population, the rise in internet use and the war in Tigray, when sexual violence was used as a weapon of war by Ethiopian and Eritrean soldiers, have all helped to create an online environment in which even femicide is considered unremarkable. AFP Fact Check collaborated with Deutsche Welle Akademie, to investigate the cyber harassment of women in Ethiopia, analysing misogynistic posts published on TikTok and Facebook. They discovered disparaging remarks about women’s physical appearance, threats of acid attacks and other physical violence, and the public sharing of women’s phone numbers. == Individuals affected == Women in particular jeopardy of digital gender-based violence are feminists, activists, politicians and those with a public profile. Some women are known to have fled Ethiopia fearing for their lives after online and offline threats. Yordanos Bezabih, an Ethiopian women’s rights activist, started a campaign with the hashtag #JusticeforHeaven to fight against gender-based cyberspace violence. As a result, she herself become a target. She experienced years of online threats of acid attacks, gang-rape and death. In 2025, subscribers to an online community organised a search for her address. Deepfake nude images of her were shared, she was filmed in real life, her house and online accounts were broken into, her private photos and messages posted on social media. When the attackers finally circulated her address, suggesting that she be executed, she left Ethiopia on a human rights defender scholarship. In 2023, Lella Misikir helped to start a campaign, called ‘My Whistle, My Voice’, that suggested women carry whistles and use them if they were harassed in the street. A TikTok video of the campaign became popular. Shortly after, videos of Misikir were circulated suggesting that she was gay. Her online attackers next searched for her address. In November 2024, Misikir left the country. == Legal issues == Ethiopia has some laws on online harassment and defamation, for example the Computer Crimes Proclamation. However, technology-facilitated, gender-based violence (TFGBV), such as deepfakes, non-consensual image sharing, and coordinated harassment, is not explicitly recognized as crime. In practice too, women are often not believed when reporting such violence and are not taken seriously. Police advice is often that women affected should simply leave the online space. Social media platforms can remove content when it is brought to their attention but the offenders are not banned. Users can only block them.
ELMo
ELMo (embeddings from language model) is a word embedding method for representing a sequence of words as a corresponding sequence of vectors. It was created by researchers at the Allen Institute for Artificial Intelligence, and University of Washington and first released in February 2018. It is a bidirectional LSTM which takes character-level as inputs and produces word-level embeddings, trained on a corpus of about 30 million sentences and 1 billion words. The architecture of ELMo accomplishes a contextual understanding of tokens. Deep contextualized word representation is useful for many natural language processing tasks, such as coreference resolution and polysemy resolution. ELMo was historically important as a pioneer of self-supervised generative pretraining followed by fine-tuning, where a large model is trained to reproduce a large corpus, then the large model is augmented with additional task-specific weights and fine-tuned on supervised task data. It was an instrumental step in the evolution towards transformer-based language modelling. == Architecture == ELMo is a multilayered bidirectional LSTM on top of a token embedding layer. The output of all LSTMs concatenated together consists of the token embedding. The input text sequence is first mapped by an embedding layer into a sequence of vectors. Then two parts are run in parallel over it. The forward part is a 2-layered LSTM with 4096 units and 512 dimension projections, and a residual connection from the first to second layer. The backward part has the same architecture, but processes the sequence back-to-front. The outputs from all 5 components (embedding layer, two forward LSTM layers, and two backward LSTM layers) are concatenated and multiplied by a linear matrix ("projection matrix") to produce a 512-dimensional representation per input token. ELMo was pretrained on a text corpus of 1 billion words. The forward part is trained by repeatedly predicting the next token, and the backward part is trained by repeatedly predicting the previous token. After the ELMo model is pretrained, its parameters are frozen, except for the projection matrix, which can be fine-tuned to minimize loss on specific language tasks. This is an early example of the pretraining-fine-tune paradigm. The original paper demonstrated this by improving state of the art on six benchmark NLP tasks. === Contextual word representation === The architecture of ELMo accomplishes a contextual understanding of tokens. For example, the first forward LSTM of ELMo would process each input token in the context of all previous tokens, and the first backward LSTM would process each token in the context of all subsequent tokens. The second forward LSTM would then incorporate those to further contextualize each token. Deep contextualized word representation is useful for many natural language processing tasks, such as coreference resolution and polysemy resolution. For example, consider the sentenceShe went to the bank to withdraw money.In order to represent the token "bank", the model must resolve its polysemy in context. The first forward LSTM would process "bank" in the context of "She went to the", which would allow it to represent the word to be a location that the subject is going towards. The first backward LSTM would process "bank" in the context of "to withdraw money", which would allow it to disambiguate the word as referring to a financial institution. The second forward LSTM can then process "bank" using the representation vector provided by the first backward LSTM, thus allowing it to represent it to be a financial institution that the subject is going towards. == Historical context == ELMo is one link in a historical evolution of language modelling. Consider a simple problem of document classification, where we want to assign a label (e.g., "spam", "not spam", "politics", "sports") to a given piece of text. The simplest approach is the "bag of words" approach, where each word in the document is treated independently, and its frequency is used as a feature for classification. This was computationally cheap but ignored the order of words and their context within the sentence. GloVe and Word2Vec built upon this by learning fixed vector representations (embeddings) for words based on their co-occurrence patterns in large text corpora. Like BERT (but unlike "bag of words" such as Word2Vec and GloVe), ELMo word embeddings are context-sensitive, producing different representations for words that share the same spelling. It was trained on a corpus of about 30 million sentences and 1 billion words. Previously, bidirectional LSTM was used for contextualized word representation. ELMo applied the idea to a large scale, achieving state of the art performance. After the 2017 publication of Transformer architecture, the architecture of ELMo was changed from a multilayered bidirectional LSTM to a Transformer encoder, giving rise to BERT. BERT has a similar pretrain-fine-tune workflow, but uses a Transformer with implications for more parallelizable training.

LiveChat
LiveChat is an AI customer service software with chatbot, online chat, help desk software, and web analytics capabilities. LiveChat is used by over 76,000 companies. It was first launched in 2002 and is offered via a SaaS (software as a service) business model by Text. Organizations use LiveChat as a single point of contact to manage customer service and online sales activities with a single program. == Product == LiveChat is proprietary software. LiveChat's website chat widget can be embedded on customers' websites as a small chat box, often displayed in the bottom right corner of the web browser. It can be used to conduct chats, share files and save transcripts. The agent application is used by company employees to respond to questions asked by the customers. This is available through both web-based application, desktop applications, and mobile apps. Web chat sessions can be initiated by the visiting customer, or by the agent, either manually or automatically by the LiveChat system when the visitor meets the predefined criteria (i.e. searched keyword, time on website, encountered error, etc.). LiveChat's system attempts to identify the best prospects visiting a website based on data gathered from past purchasing decisions. Other features include real-time website traffic monitoring, built-in ticketing system and agents' efficiency analytics. LiveChat is available in 48 languages. == Research and reception == Reviewing LiveChat's usefulness for online learning in 2020, psychologist Jaclyn Broadbent said "LiveChat occurs as a real-time conversation, it can be time-consuming for staff and disruptive to other tasks." However, using it has resulted in reduced communication traffic from other channels, such as the discussion boards or email. As a teacher, the best time to be available on LiveChat is when you are doing other administrative jobs." Since 2014 LiveChat has been publishing Customer Service Report - an annual study of customer satisfaction and analysis of online business communication trends. It includes research of thousands of companies and millions of customer service email and live support interactions.
