The book copies the aim of the podcast to make the invisble visible and point the reader to design in cities and the cool stories behind it. It is divided […]
Summary of week four for the course Knowledge Engineering with Semantic Web Technologies 2015 by Harald Sack at OpenHPI. RDFS Semantics: we need this because there was no formal description of the semantics and then the same querys gave back different results. So you add semantics. Every triple encoded in RDF is a statement and […]
Summary of week three for the course Knowledge Engineering with Semantic Web Technologies 2015 by Harald Sack at OpenHPI. This lecture deals with ontologies. If you want to speak a common language, you need: common symbols and concepts (Syntax) agreement about their meaning (Semantics) classification of concepts (Taxonomy) associations and relations of concepts (Thesauri) rules […]
Summary of week two for the course Knowledge Engineering with Semantic Web Technologies 2015 by Harald Sack at OpenHPI. Reification allows you to make reference statements. Therefore a statement also gets an URL. It also allows you to make statements about statements and assumptions about assumptions (e.g. Sherlock Holmes thinks that the gardener murdered the […]
Summary of week sic for the course Knowledge Engineering with Semantic Web Technologies 2015 by Harald Sack at OpenHPI. Linked Data Engineering In general it is difficult to get data, because it is distributed into different databases and you need different APIs to get the data -> data islands. Applying semantic web technologies allows you […]
Summary of week five for the course Knowledge Engineering with Semantic Web Technologies 2015 by Harald Sack at OpenHPI. Ontology Engineering Pyramid for knowledge management: Data: raw data, facts about event Information: a message to change the receiver’s perception Knowledge: experience, context, information + semantics Wisdom: application of knowledge in context In general it makes […]
Summary of week one of the MOOC Artificial intelligence at edx. The lecture deals with artificial intelligence, which means in this context, that we want to program computers that act logically, we do not want them to act like humans and we also do not want to build an artificial brain to understand how human […]
Summary of week one for the course Knowledge Engineering with Semantic Web Technologies 2015 by Harald Sack at OpenHPI. The first week covers the basic principles of the technologies for the semantic web, especially RDF, which is one of the languages you can use for encoding information semantically. The basic principle behind the technologies are […]
