License-Aware Web Crawling for Open Search AI (LAW4OSAI)

The LAW4OSAI (License-Aware Web Crawling for Open Search AI) project aims to enable license-aware crawling of web content by automatically identifying and retrieving content licenses. The goal is to enable open web search filtered by licenses and more importantly the development of open large language models for next-generation search technology, like conversational search or image generation, that respect the rights of authors and copyright. We want to foster and interdisciplinary exchange between legal experts interested in copyright and technology law and the technical parts of the open web search community.

Software Aided Analysis of Terms of Services (SaToS)

The phrase "I have read and understood the terms of service" is often referred to as the biggest lie on the internet. Every time we buy something online, we are confronted with Terms of Services (ToS). However, only a few people actually read these terms, before accepting them, often to their disadvantage. General terms and conditions included in standard form contracts are of significant economic value, as most companies use these terms when entering into contractual relationships with their customers. The interdisciplinary computer and legal science research project SaToS (Software Aided Analysis of ToS) from the chair of Software Engineering for Business Information Systems (sebis) at TU Munich aims to automatically identify Terms of Services and summarise them with regard to their lawfulness and customer friendliness, in a simplified language. In this way, SaToS aims to empower customers to make educated decisions about where to buy or not within seconds, directly addressing the imbalance of powers and fostering the constitutional principle of legal clarity.

Meta Model based Natural Language Generation for Automatic Abstractive Text Summarization (A-SUM)

More than 5000 years after its invention, written language is still the most important medium to document and communicate knowledge. While the production of texts is simplified and accelerated by word processing software, template systems and other technologies, the consumption of texts is still a comparably little by technology supported process. The current state-of-the-art in automatic text summarization are mostly so called extractive methods, which extract the n most important sentences of a text by the means of metrics like TF/IDF. These summaries consist of mostly incoherent sentences. The goal of the BMBF founded Software Campus Project "Meta Model based Natural Language Generation for Automatic Abstractive Text Summarization" (A-SUM) is the creation of coherent, personalized automatic abstractive summaries. Instead of just extracting sentences, A-SUM aims to extract facts from texts and store them in an intermediate, meta model based, structured format. Based on user preferences and contextual information, this information can be personalized. By applying Natural Language Generation techniques, we aim to transform the structured representation of information back to a coherent text, which gives the recipient a quick and tailored overview of the content of the original text.

AI-Supported Legal Review of Terms and Conditions to Strengthen Consumer Protection (AGB-Check)

The advancing digitization is increasingly influencing everyday work in so-called ā€œknowledge-intensiveā€ professions. Software that supports experts in dealing with legal texts and questions is often summarized under the term "Legal Tech". In theory, it can help make legal expertise available more quickly and cheaply, and hence making it more accessible, especially for consumers. In practice, however, the necessary technologies are often only available to commercial actors. The goal of AGB-Check is the development of innovative technologies that support legal knowledge workers in their efforts to represent the interests of consumer in the digital age better and more effectively. Using the example of a specific application - automated legal reviews of terms and conditions - we want to research technologies that: Support experts in dealing with German legal texts by automatically analyzing them semantically and classify them regarding their legality Enables geographically and organizationally separated experts to participate together in the learning and development process of legal expert systems Allow to combine machine learning and rule-based techniques to process German legal texts to in hybrid systems
