"Software Knowledge" – in short SKY – means that software in its higher abstraction levels is a new kind of knowledge, Runnable Knowledge.
Thus, the classes and relationships of a software UML diagram are easily viewed as the classes and relationships of a knowledge ontology.

The main theme of the SKY2012 Workshop is Between Software Models and Ontologies.
We mean rigorous and precise transformations back and forth between Software System Models and their respective Runnable Knowledge given by Ontologies.

The Workshop main objective is to offer rigorous transitions between high-level abstractions found in software models and suitably modified knowledge ontologies.
Among its goals we aim at a quantitative and generic measure of meaning, based upon graph models such as ontologies.
Topics of Interest
Software-Knowledge is the highest of a software hierarchy of abstraction levels.
Thinking Software as Knowledge opens the possibility to apply Knowledge processes, models, and tools to improve Software discovery, development, management and deep understanding.

Software Knowledge is a runnable expression of meaning.
We refer to the observation that running facilitates understanding in a very general sense. A high-brow example is the need to read again and again poetry to understand its meaning. A more down to earth instance is the debugging process, where one runs and breaks at desired points to understand the reason of software failures.

SKY2012 topics of relevance include but are not limited to:

Software-Knowledge Hierarchy and Operations
  • Software-Knowledge selectivity and traceability
  • Software-Knowledge Sharing: Meta-models, interchange formats, and tools
  • Knowledge Driven Architecture and Engineering
Software-Knowledge Runnability and Meaning
  • Software-Knowledge representation and modeling
  • Semantic Software Representations (SKOS, Ontologies, and more)
  • Semantics above and beyond design patterns
  • Runnable and testable knowledge representations
  • Web dynamics and interestingness
  • Ontologies in complex systems
Expected Outcomes
Expected outcomes of the SKY2012 Workshop are:

⇒ A continuing effort to standardize a Software-Knowledge representation consisting of software modeling language encompassing semantics as first class objects.

⇒ Proposals for quantitative expressions of meaning based upon graph models.

Invited Speakers
Following the tradition established in previous years, SKY'2012 invites recognized researchers to deliver invited talks in the workshop:

Dr. Hugo Zaragoza – founding CEO of Websays

Exploiting Extraction Technology for Search Applications

Information Extraction and Parsing technology allows us to transform natural language text into rich representations that enable new forms of search an data analysis. However, many challenges need to be overcome in multiple areas: extraction and machine learning, adaptation and use of ontological information, indexing and querying performance, and interface design. I will discuss these challenges illustrating with examples of my own work at Yahoo! Research and Websays.

Brief Bio
Hugo Zaragoza is founding CEO at Websays, a start-up specializing in online reputation and opinion mining. Before this Hugo led the Natural Language Retrieval group at Yahoo! Research Barcelona. He is interested in the applications of machine learning (ML) and natural language processing (NLP) for information retrieval (IR), Web search, and information access in general. Before joining Yahoo!, Hugo worked at Microsoft Research mostly on probabilistic ranking methods for corporate and web search, but also on document classification, expert finding, relevance feedback, and dialogue generation for games. He also collaborated with Microsoft product groups MSN-Search (now Bing) and SharePoint. Prior to Microsoft Research, Hugo taught computer science and completed a Ph.D. at the LIP6 (U. Paris 6).
