The document discusses recommendations for surfacing interesting, new, and relevant programs to individual and group users. It proposes combining statistical and semantic approaches in a complementary way. For the semantic recommendation approach, it involves analyzing linked open data sources to identify popular types and properties, and selecting relevant types and their patterns. User and program data would be enriched with concepts from knowledge bases before applying recommendation algorithms.
The document discusses user profiling and recommendation approaches. It describes extracting user interests from social media activities, representing interests as linked data identifiers, and addressing challenges like noise from record linkage. It also discusses generating recommendations using semantic, statistical, and hybrid approaches by analyzing user profiles and program metadata. Analytics on user profiles and activities are performed by the "Beancounter" system to support recommendations.

Semantic Digital Humanities Workshop 2015 @OxfordLora Aroyo
Lora Aroyo presents on open, connected, and smart heritage and new cultural commons. She discusses how crowdsourcing can be used to gather diverse perspectives from users to expand expert vocabularies and gather new types of metadata. Three case studies are presented: crowdsourcing video tags at Sound and Vision, where 340,551 tags were added by 555 registered users; tagging 1,782 works of art across 11 museums, gathering 36,981 tags from 2,017 users; and the Waisda project, where user tags improved search accuracy by 53% compared to consensus tags alone.
Lecture 5: Personalization on the Social Web (2013)Lora Aroyo
The document discusses personalization and user modeling on the social web. It describes how user data is generated from various online activities and interactions that can be used to create user profiles and models. Several approaches for developing user models are presented, including overlay models that describe user characteristics, elicitation models that ask users for information or observe their behaviors, stereotyping models that apply typical attributes to users, and relevance models that learn what items are pertinent. The best approach depends on the specific application conditions.
The document discusses how television is evolving from a closed system to an open, personalized, and social experience on the web. It notes that while personalized access to TV content is in demand, challenges remain around privacy and the use of user data for recommendations. New approaches are needed that combine both statistical and semantic analysis of content and user preferences to provide recommendations that balance relevance, diversity, and serendipity. The talk presents examples of how a system called NoTube is aiming to deliver this new vision of social and personalized television.

Framing Few Shot Knowledge Graph Completion with Large Language ModelsMODUL Technology GmbH
Knowledge Graph Completion (KGC) from text involves identifying known or unknown entities (nodes) as well as relations (edges) among these entities. Recent work has started to explore the use of Large Language Models (LLMs) for entity detection and relation extraction, due to their Natural Language Understanding (NLU) capabilities. However, LLM performance varies across models and depends on the quality of the prompt engineering. We examine specific relation extraction cases and present a set of examples collected from well-known resources in a small corpus. We provide a set of annotations and identify various issues that occur when using different LLMs for this task. As LLMs will remain a focal point of future KGC research, we conclude with suggestions for improving the KGC process.
Unsupervised Topic Modeling with BERTopic for Coarse and Fine-Grained News Cl...MODUL Technology GmbH
Transformer models have achieved state-of-the-art results for news classification tasks, but remain difficult to modify to yield the desired class probabilities in a multi-class setting. Using a neural topic model to create dense topic clusters helps with generating these class probabilities. The presented work uses the BERTopic clustered embeddings model as a preprocessor to eliminate documents that do not belong to any distinct cluster or topic. By combining the resulting embeddings with a Sentence Transformer fine-tuned with SetFit, we obtain a prompt-free framework that demonstrates competitive performance even with few-shot labeled data. Our findings show that incorporating BERTopic in the preprocessing stage leads to a notable improvement in the classification accuracy of news documents. Furthermore, our method outperforms hybrid approaches that combine text and images for news document classification.

This document presents a study on using computer vision techniques to analyze visual destination branding on Instagram. Specifically, it discusses fine-tuning a state-of-the-art deep learning model to classify destination photographs into exclusive and exhaustive cognitive attributes of destination image. This trained model can then be used to extract and compare multi-dimensional vector representations of destinations' visual brand images based on the classification of photo datasets from their Instagram hashtags. The implications and opportunities identified from comparing destinations' visual brand images can help tourism marketers assess marketing success and identify brand attributes to promote or improve upon.

The document describes a study that used a deep learning classifier to analyze Instagram photos and measure destination image. The study found that existing visual classifiers were not well-suited for tourism analysis. It created a new classifier trained on tourism categories and photos to more accurately measure destination image. The classifier was then used to analyze Instagram photos from several DMOs and compare their projected image to the perceived image based on user-generated photos. The results demonstrated how visual classifiers can provide insights into a destination's image online and help DMOs better understand travelers' perceptions.

This presentation considers if, and to what extent, visual social media can change the viewer’s perceived image of a tourism destination as well as which types of visual content are most effective in projecting a destination image. The results from an online survey, which compared three different test groups and their image of Mexico City, showed that UGC images from Instagram, as well as random Google images, were more effective at improving destination image than the UGC images reposted by a DMO. Additionally, the study used image annotations to determine which features in images were most important in terms of their contribution to an improvement in overall destination image, presenting a re-usable set of visual features for future work on using annotations in the measurement of visual destination image.

This study examined how Instagram influences the visual destination image of Jordan and Costa Rica. Researchers conducted an experiment showing participants Instagram photos of each destination categorized by nature, culture, and food/drink. They measured participants' destination image ratings before and after viewing photos. For nature images, Costa Rica's ratings increased more than Jordan's. For culture, Jordan's ratings rose higher. For food/drink, Costa Rica again saw greater improvement. The researchers concluded destinations should market a variety of characteristics to build a well-rounded image, and more research is needed on using different visual media to influence destination image.
I address the rapid increase in non-textual content being shared online around tourism destinations and how this necesitates new media technologies for tourism stakeholders such as DMOs. Current platforms for "tourism intelligence" (providing actionable insights to tourism marketers based on online analysis of the discussions and content around their destinations) rely on text; to add images and videos at scale we would need accurate machine annotation. My talk will provide initial insights into this field of study and hopefully encourage a greater consideration of how to handle multimedia in future tourism research.
The document provides an overview of dissemination activities for the NoTube project, including a website (notube.tv) that hosts online and printed showcase materials. It discusses other dissemination channels like presentations, publications, and events, as well as contributions to standards and recommendations. The dissemination efforts are led by Lyndon Nixon of STI International with support from project partners.
The document summarizes the NoTube WP7c project, which explored social media and TV. It identified key user questions about watching TV together and finding things to watch. The N-Screen application allowed sharing recommendations and controlling TV via drag-and-drop between devices. User testing found that people enjoyed getting recommendations from friends but were less interested in explanations. Users want to watch TV socially but not always at the same time, and they will trade privacy for personalized recommendations. Technical challenges included pairing and synchronizing devices.
The document outlines the goals and progress of the WP7b project. The goals included: [1] designing a personalized program guide, [2] developing a TV program recommendation system, [3] creating a multi-device and multi-modal program guide, [4] supporting multiple languages, and [5] personalized advertising placement in videos. It describes the NoTube architecture supporting these goals and the development of personalized recommendations. It also demonstrates multi-lingual and multi-device interfaces, and evaluates the recommendation explanations feature.
This document discusses the development of a personalized semantic news service called WP7a. It aggregates news items from various sources and enriches them with related web resources, taking into account user behaviors and preferences. Three prototypes were developed and evaluated over three years. Testing showed a 97% improvement in user experience with the final handheld device-based prototype compared to earlier versions. Lessons learned include the potential for collaboration between television, the internet and social networks to deliver personalized news and content.
Fabio Cattaneo of Polymedia presented on the NoTube project's final platform architecture and sustainability plans. The presentation summarized the goals and achievements of Year 3, including developing a user portal with profile management, activity logging, and app integration capabilities. It also evaluated popular platforms, mainstream solutions, and compared NoTube's services and social features. Finally, it discussed Polymedia's plans to continue developing social TV products after NoTube and opportunities to impact standards bodies and related projects.

The document summarizes work on loudness normalization for web content. It provides:
1) A web service for loudness normalization compliant with ITU and EBU standards.
2) Loudness analysis results to support ad insertion.
3) Evaluation of loudness normalization on the web which found homogeneous results for loudness adaptation and a preference for medium to strong loudness range compression.
The document discusses improvements made to an algorithm for automatically inserting advertisements (ads) into videos. Survey results from testing the algorithm showed some sequences were ranked poorly by users despite a good algorithm score. The algorithm was modified to consider additional factors like audio, scene cuts, and global saliency to better identify sequences suitable for ad insertion. A second survey found most sequences were acceptable to users and half were good to very good, but acceptance varied significantly between different movies.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
