Geographic tools have emerged that use open-standards and support users creating and sharing their own geodata. Together, these tools form a GeoStack that enable the entire lifecycle of data. Publish Blogging tools, geotagged photographs, mobile devices, and geolocation enable people to capture and share their stories, travels, and news. Sites like Platial, Flickr, or Ning have also embraced open standards, allowing users to export and reuse their data. Transport GeoRSS, KML, and GPX are just some of the data format standards that can carry geographic information from provider to consumer. Aggregate Services such as Mapufacture mix and match feeds of data from their source to potential users. Keyword and geographic searches can provide useful collections from various sources. Consume Mapstraction, OpenLayers, GoogleEarth, and other geographic visualization libraries and tools make it possible to view and display various geographic information. In addition, it is possible to store user-created maps and points of interest to their mobile devices and GPS receivers for use when on the move. This talk will discuss the technologies that currently comprise the GeoStack and how it is enabling users to share and use geographic data. Developers can fit their tools into any point along this stack, or add to existing services. We'll also discuss the future of the geotools. O'Reilly Home |

It’s easy to find and create data. But what are you going to do with it? Can I ask the world complex questions such as what’s the local crime rate, distance to metro, or rating of my local school? Can you combine these all together to rate houses you may want to buy? And how do you then connect back to your government and local businesses to engage in collaborative decision making. This talk with discuss how you should consider users and their personal interactions with data and information. We’ll also peel back the covers on how open source tools such as HBase, Cascading, Geos and Polymaps handle analyzing and streaming realtime data to maps and visualizations both on the web and to mobile devices. To illustrate what’s possible, we’ll dive through GeoCommons, a large online community of data sharing and community analytics that uses open source mapping visualization, Hadoop analysis, and mobile interfaces to provide this to the world. Users can even build and socialize their own analysis methods to share their expert knowledge with other users. We’ll also review how global organizations like the World Bank and United Nations are using these tools to connect with citizens in developing countries to empower them to make decisions on building investment and understanding how climate science may affect their areas.

Sara Mae O’Brien Scott and Tatiana Baquero Cakici, Senior Consultants at Enterprise Knowledge (EK), presented “AI Fast Track to Search-Focused AI Solutions” at the Information Architecture Conference (IAC24) that took place on April 11, 2024 in Seattle, WA. In their presentation, O’Brien-Scott and Cakici focused on what Enterprise AI is, why it is important, and what it takes to empower organizations to get started on a search-based AI journey and stay on track. The presentation explored the complexities of enterprise search challenges and how IA principles can be leveraged to provide AI solutions through the use of a semantic layer. O’Brien-Scott and Cakici showcased a case study where a taxonomy, an ontology, and a knowledge graph were used to structure content at a healthcare workforce solutions organization, providing personalized content recommendations and increasing content findability. In this session, participants gained insights about the following: Most common types of AI categories and use cases; Recommended steps to design and implement taxonomies and ontologies, ensuring they evolve effectively and support the organization’s search objectives; Taxonomy and ontology design considerations and best practices; Real-world AI applications that illustrated the value of taxonomies, ontologies, and knowledge graphs; and Tools, roles, and skills to design and implement AI-powered search solutions.

Heather Hedden, Senior Consultant at Enterprise Knowledge, presented “The Role of Taxonomy and Ontology in Semantic Layers” at a webinar hosted by Progress Semaphore on April 16, 2024. Taxonomies at their core enable effective tagging and retrieval of content, and combined with ontologies they extend to the management and understanding of related data. There are even greater benefits of taxonomies and ontologies to enhance your enterprise information architecture when applying them to a semantic layer. A survey by DBP-Institute found that enterprises using a semantic layer see their business outcomes improve by four times, while reducing their data and analytics costs. Extending taxonomies to a semantic layer can be a game-changing solution, allowing you to connect information silos, alleviate knowledge gaps, and derive new insights. Hedden, who specializes in taxonomy design and implementation, presented how the value of taxonomies shouldn’t reside in silos but be integrated with ontologies into a semantic layer. Learn about: - The essence and purpose of taxonomies and ontologies in information and knowledge management; - Advantages of semantic layers leveraging organizational taxonomies; and - Components and approaches to creating a semantic layer, including the integration of taxonomies and ontologies

Scaling API-first – The story of a global engineering organization

Radu Cotescu

The presentation explores the development and application of artificial intelligence (AI) from its inception to its current status in the modern world. The term "artificial intelligence" was first coined by John McCarthy in 1956 to describe efforts to develop computer programs capable of performing tasks that typically require human intelligence. This concept was first introduced at a conference held at Dartmouth College, where programs demonstrated capabilities such as playing chess, proving theorems, and interpreting texts. In the early stages, Alan Turing contributed to the field by defining intelligence as the ability of a being to respond to certain questions intelligently, proposing what is now known as the Turing Test to evaluate the presence of intelligent behavior in machines. As the decades progressed, AI evolved significantly. The 1980s focused on machine learning, teaching computers to learn from data, leading to the development of models that could improve their performance based on their experiences. The 1990s and 2000s saw further advances in algorithms and computational power, which allowed for more sophisticated data analysis techniques, including data mining. By the 2010s, the proliferation of big data and the refinement of deep learning techniques enabled AI to become mainstream. Notable milestones included the success of Google's AlphaGo and advancements in autonomous vehicles by companies like Tesla and Waymo. A major theme of the presentation is the application of generative AI, which has been used for tasks such as natural language text generation, translation, and question answering. Generative AI uses large datasets to train models that can then produce new, coherent pieces of text or other media. The presentation also discusses the ethical implications and the need for regulation in AI, highlighting issues such as privacy, bias, and the potential for misuse. These concerns have prompted calls for comprehensive regulations to ensure the safe and equitable use of AI technologies. Artificial intelligence has also played a significant role in healthcare, particularly highlighted during the COVID-19 pandemic, where it was used in drug discovery, vaccine development, and analyzing the spread of the virus. The capabilities of AI in healthcare are vast, ranging from medical diagnostics to personalized medicine, demonstrating the technology's potential to revolutionize fields beyond just technical or consumer applications. In conclusion, AI continues to be a rapidly evolving field with significant implications for various aspects of society. The development from theoretical concepts to real-world applications illustrates both the potential benefits and the challenges that come with integrating advanced technologies into everyday life. The ongoing discussion about AI ethics and regulation underscores the importance of managing these technologies responsibly to maximize their their benefits while minimizing potential harms.
