The document outlines a framework for identifying and categorizing elementary end-user tasks in the semantic web, aimed at improving user experience. It discusses various tasks including search, browse, annotate, mashup, map, share, communicate, and transact, highlighting differences between traditional web and semantic web approaches. Future work will involve modeling interaction patterns and developing a recommender system for semantic web user interfaces.

- 1. Semantic Web End-User Tasks Alfons Palacios¹,² Roberto García¹ Marta Oliva¹, Toni Granollers¹ ¹ GRIHO – Universitat de Lleida ² Tecnocampus Mataró - Universitat Pompeu Fabra
- 2. Agenda • Purpose • Motivation • Semantic Web-User Tasks • Search • Browse • Annotate • Mashup • Map • Share • Communicate • Transact • Conclusions and FutureWork
- 3. Purposes • Define a catalogue of elementary SemanticWeb End-User Tasks • Describe how Web End-User Tasks are applied and extended in the SemanticWeb, opportunities • Compare, aggregate and complete related proposals: - Heath, Kellar, Battle, Mäkelä, Di Maio, Sabou... • Create guidelines that help improve the user experience with the SemanticWeb
- 4. Motivation and Route Plan 1. Establish a catalogue of elementary Semantic Web End-User Tasks 2. Define a Inventory of Interaction Patterns and classify them according to SW End-User Tasks 3. Model interaction patterns, formal model using ontologies 4. Create a recommender that guides Semantic Web user interfaces development (considering user profiles, devices,…)

- 6. Search •Web: - Usually keyword based search or set of forms (advanced search) - Also monitoring (delayed search eventually repeated in the future) •• Semantic Web: - Knowledge captured in ontologies guides the user through the query construction process, facilitate query by example or results display
- 7. Browse •Web: - The user “moves” through information being displayed, usually following links •• Semantic Web: - Browse links between resources, not documents - Use data structure to generate Information Architecture (e.g. menus, facets, treemaps,…)
- 8. Annotate •Web: - Tagging a photo or a bookmark •• Semantic Web: - Annotations follow a conceptual model - Models assist users and help validation - Autocomplete, entity recognition, SEO,…
- 9. Annotate – Semantic Web media: dc: Ronaldo V-Football : Games (1 Review) - $32.45 as of May 25, 2000 Juego de fútbol que cuenta como reclamo principal con la presencia de Ronaldo como estrella indiscutible… Translate http://www.meristation.com/v3/todosobre.php?idj=1818 - Cached image description product: product: manufacturer salePrice product: vcal: currency d t review: review: rating text date Rich Snippets Schema.org
- 10. Mashup •Web: - Mix different information sources - Usually limited to news feeds, RSS… • Semantic Web: - Highly structured data helps mixing - Ontologies and reasoning capabilities automate much of the effort - Data reuse can drive website generation, cost reduction, open data ecosystem,…
- 11. Mashup – Semantic Web
- 12. Map •Web: - Rare in the context of the Web - Example: define mappings among hashtags (http://tagdef.com) •• Semantic Web: - Relate tags, terms, concepts, classes,… from different vocabularies - Mapping might facilitate or automate mashups
- 13. Share •Web: - Uploading, publishing, updating, deleting of data, photos, videos… making them available to other users •• Semantic Web: - Might be enriched by triggering content indexing or automatic metadata generation (entity recognition) RDFaCE
- 14. Communicate •Web: - Chat, e-mail, videoconference,... • Semantic Web: - Automatic annotations for conversation contextualisation, integrate conversations through different channels, actionable content (detailed next)
- 15. Transact •Web: - User actions that provoke a change in the state of a real-world entity or of a resource in another system - Buying a book, ordering a money transfer • Semantic Web: - Web-wide object-action interaction pattern (Shneiderman) - Gmail schema.org semantic annotations for objects and available actions (dynamically linked)
- 16. Conclusions and Future Work • Proposed Semantic Web End-User Tasks nicely covers existing tasks proposals and Semantic Web tools •• Also classifies interaction patterns for an inventory of Semantic Web interaction patterns (work in progress) - Tidwell, van Welie, Toxboe, Yahoo!, Crumlish&Malone... • Next… - Model interaction patterns using ontologies - Define recommender for Semantic Web UI development - Test using Rhizomer, automatic UI generation from Semantic Web data
