SPARQL and SQL: technical aspects and synergy
This document discusses the technical aspects and synergy between SPARQL and SQL. SPARQL is designed to query collections of RDF triples and easily traverse relationships, with a syntax resembling SQL. SPARQL can be translated to SQL and works with popular web protocols. It consists of pattern matching, solution modifiers, and output. SPARQL applications include interrogating RDF engines, and it can work with RDFS reasoning. The document also discusses how SPARQL relates to rules for the semantic web, and compares SPARQL and SQL for finding and matching data from tabular and graph-based representations.
Information Flow based Ontology Mapping - 2002
This document presents an information flow (IF) based approach to ontology mapping. It introduces a theory of ontology mapping based on channel theory and mathematical information flow. It then describes a methodology and prototype implementation of IF-Map, which uses classifications and infomorphisms to systematically map concepts and relations between ontologies. The methodology is demonstrated on a test case mapping between AKT Reference and Southampton/Edinburgh ontologies. Extensions to ontology merging and evolution are also discussed.

The document proposes a five-layer semantic grid architecture with a knowledge layer on top of the Gridbus broker. The knowledge layer includes two modules: semantic description and discovery. Semantic description represents grid domain knowledge in an ontology template using Protege-OWL APIs. Semantic discovery uses the Algernon inference engine to retrieve resource information based on user queries. This knowledge layer is implemented in the Gridbus broker and can support popular middleware like Globus and Alchemi.

Semantic opinion mining ontology
This document discusses feature extractions based semantic sentiment analysis. It begins with an introduction to opinion mining and sentiment analysis. It then discusses how ontologies can be used to structure information and provide a formal knowledge representation for sentiment analysis. Building detailed ontologies for particular domains allows semantics to be applied to opinion mining by identifying useful features using the ontology. Opinion mining approaches can then be used for efficient sentiment classification. Examples of using movie ontologies to identify concepts and properties for feature-level sentiment analysis are also provided.

Towards a comprehensive call ontology for research 2.0
This document proposes a comprehensive call ontology for research to better organize and semantically tag calls for papers (CfPs). It analyzes current CfP practices like mailing lists, blogs and web services which lack semantic search capabilities. The proposed ontology defines concepts for events, submissions, dates, publications, people and organizations. Two usage scenarios are described: a Timeliner tool to aggregate CfPs on a collaborative timeline, and a conference management system called Ginkgo that could implement the call ontology.
Poster
The Picat language integrates logic programming, imperative programming, functional programming, and constraint programming. It allows modeling and solving combinatorial search problems through constraints and SAT/MIP solvers. While similar to Prolog, Picat uses pattern matching instead of unification and allows non-determinism through tabling. It is dynamically typed like Python but can also express computations functionally like Haskell. The language provides tools for tasks like constraint solving, planning, NLP, and data processing.
Nikolay Karpov - Evolvable Semantic Platform for Facilitating Knowledge Exchange
This document describes an evolvable semantic platform called EXPERTIZE that was developed to facilitate knowledge exchange between experts at a university.

The goal is to help bridge the gap between ontology engineering and application development.
Semantic Interoperability problem of OSS Forges
The presentation was given at the ICSEA 2009 and refers to the paper (with the same title) submitted for the conference. The abstract of the paper is following: "Interoperability between collaborative development platforms (forges) in the Open Source Software world is a significant issue. The forges tend to follow the lock-in phenomenon, providing no easy-to-use facilities for migrating projects or their parts between forge platforms. To facilitate the process of cross-forge project migration, the following paper presents an approach of lifting forge data models to the semantic level and applying rule-based mappings for their alignment. The approach also involves Semantic Web Services to handle the process of importing/exporting project metadata from/to Open Source Software forges. Finally, the paper demonstrates the approach on the basis of proof-of-concept implementation exploiting the existing forges and presents the lessons learnt.

CrossSim: exploiting mutual relationships to detect similar OSS projects
Slides presented at SEAA 2018 http://dsd-seaa2018.fit.cvut.cz/seaa/ related to the paper http://reposto.di.univaq.it/aigon2/index.php/attachments/single/211
Software development is a knowledge-intensive activity, which requires mastering several languages, frameworks, technology trends (among other aspects) under the pressure of ever-increasing arrays of external libraries and resources.
Recommender systems are gaining high relevance in software
engineering since they aim at providing developers with real-time recommendations, which can reduce the time spent on discovering and understanding reusable artifacts from software repositories, and thus inducing productivity and quality gains.
In this presentation, we focus on the problem of mining open source software repositories to identify similar projects, which can be evaluated and eventually reused by developers. To this end, CROSSSIM is proposed as a novel approach to model open source software projects and related artifacts and to compute similarities among them. An evaluation on a dataset containing 580 GitHub projects shows that CROSSSIM outperforms an existing technique, which has been proven to have a good performance in detecting similar GitHub repositories.

Ontologies and semantic web
Ontologies provide a shared understanding of a domain by formally defining concepts, properties, and relationships. An ontology introduces vocabulary relevant to a domain and specifies the meaning of terms. Ontologies are machine-readable and enable overcoming differences in terminology across complex, distributed applications. Examples include gene ontologies, pharmaceutical drug ontologies, and customer profile ontologies. Semantic technologies use ontologies to provide semantic search, integration, reasoning, and analysis capabilities.
The Exploitation of OpenAPI Documents for the Generation of Web Frontends

Semantic technologies at work
The document summarizes a talk on semantic technologies and interoperability. It discusses the emergence of semantic technologies from academia to industry applications, drivers like the Semantic Web and Web 2.0, and using semantic technologies to enable interoperability through methods like ontology mapping and coordination. Examples of applying these methods to scenarios in academia, government, bioinformatics, and emergency response are also provided. Issues regarding adoption of semantic technologies and their use in other domains like mobile web 2.0 are briefly discussed.
E Res Akt Finalreview
The document describes an emergency response demonstration that uses semantic web technologies to help coordinate emergency services. The demonstration involves a cargo plane crashing in London, causing multiple fires. It shows how an emergency response system could help the Joint Emergency Services Control Centre make sense of the emergency, handle information requests, and make tactical decisions by integrating technologies like ontology mapping, image retrieval, and data management. The goal is to effectively acquire, analyze, and use information in real-time during an emergency response.
Advanced Knowledge Technologies (AKT) -highlights 2006
This document outlines several projects conducted by AKT including building knowledge bases, semantic integration work, and mobile semantic applications. It discusses the CROSI project which developed a modular architecture for semantic integration including generating ontology features, feature matching, and similarity aggregation. It also mentions other projects involving building ontologies for accessing life science data, semantic ranking of ontologies, mobile semantic services, and using classifiers to analyze multimedia features and relate them to domains.

On the Emergent Semantic Web and Overlooked Issues - 2004
The document discusses several vulnerabilities and overlooked issues regarding the emergent Semantic Web, including challenges around agency coordination and mechanized trust, robust reasoning over incomplete and inconsistent knowledge, and achieving semantic interoperability across diverse ontologies and representations. While significant progress has been made in developing technologies and standards for the Semantic Web, the authors argue more work is still needed to address these issues in order to realize the full vision of the Semantic Web as a means of integrating information from a variety of sources.
Using Ontologies to Support and Critique Decisions - 2004
The document discusses using ontologies to support decision making and knowledge management. It proposes two ontology-based approaches:
1) Ontology Network Analysis (ONA) which uses relationships in populated ontologies to automatically select important resources for inclusion in an organizational memory or to identify communities of practice.
2) Applying experience factories and bases from software engineering to critique and validate design decisions using ontologies. This allows experience to be reused across similar ontology development projects.
