== Welcome to the Workshop on Ontology Patterns - WOP2009 ==
This is the first edition in a series of yearly workshops addressing the emerging topic of ontology patterns as best practices, related to the [[Ontology_Design_Patterns_._org_(ODP) |''ontologydesignpatterns.org'']] initiative. Patterns need to be shared by a community in order to provide a common language and stimulate pattern usage and development. Hence, the aim of this workshop is twofold; both providing an arena for proposing and discussing good practices, patterns, pattern-based ontologies, systems etc., and broadening the pattern community that will develop its own “language” for discussing and describing relevant problems and their solutions.

The first workshop will be held in conjunction with [http://iswc2009.semanticweb.org/ ISWC], at a [http://iswc2009.semanticweb.org/wiki/index.php/Westfields_Conference_Center venue] in the Washington DC area (US), on October 25th 2009. It will be a full-day workshop consisting of three parts; paper presentations, posters, and “pattern writing” sessions. For the pattern writing sessions ontology design patterns will be submitted and reviewed at [[Ontology_Design_Patterns_._org_(ODP) |''ontologydesignpatterns.org'']], including the assignment of an advisor for each accepted pattern submission.

== Workshop Focus and Relevance ==
As interest in the Semantic Web increases and technologies for realizing the semantic web become more mature, the need for high-quality and reusable semantic web ontologies increases. To address the quality and reusability issues, different types of Ontology Design Patterns (ODPs) have emerged. Patterns can supply ontology designers with several kinds of benefits, including a direct link to requirements, reuse, guidance, and better communication. ODPs are well on their way to providing those benefits. ODPs have been [http://www.w3.org/2001/sw/BestPractices/OEP/ proposed by the W3C] and are currently being collected in various repositories, such as the [http://www.gong.manchester.ac.uk/odp/html/index.html catalogue maintained by the University of Manchester] and the ODP portal at [[Ontology_Design_Patterns_._org_(ODP) |ontologydesignpatterns.org]]. However, pattern catalogues are still small and do not cover all types of patterns and all domains. Semantic Web applications could also benefit from additional types of patterns, such as knowledge patterns and specialized software patterns for semantic applications. In addition, to achieve communication benefits, patterns need to be shared by a community in order to provide a common language for discussing and understanding modeling problems. The workshop can leverage the activities conducted in the ontologydesignpatterns.org initiative, and aims to use the portal as its main means of communication, e.g. for pattern submission, reviewing and discussions outside the workshop schedule.

Reuse has been an important research subject in ontology engineering for many years, and this is also true for the semantic web community. Patterns are an approach to knowledge reuse that has proved feasible and very profitable in many other areas such as software engineering and data modeling. During the past few years, patterns for semantic web ontologies and ontology-based applications have been introduced, and at this point in time we believe that the community would highly benefit from a series of workshops focusing on this particular topic. An earlier workshop, [http://www.research.ibm.com/people/w/welty/OPSW-05/ Ontology Patterns for the Semantic Web] , was arranged at ISWC2005, however at that time the community was considerably smaller. The focus then was on discussing reusable OWL and RDF ontologies addressing general open problems. The WOP series broadens this scope to include all patterns related to ontology design and knowledge engineering for the Semantic Web. This is in line with the successful [http://ekaw2008.inrialpes.fr/ EKAW2008] conference (with the sub-title Knowledge Patterns). Topics of this conference included ontology engineering patterns but also patterns for re-engineering of knowledge resources, process knowledge, social and cognitive aspects of semantics.

A workshop should be a practical and interaction-rich event, hence the workshop will have three parts: regular papers, posters, and “pattern writing”, with a focus on the latter. The inspiration for this model comes from the [http://hillside.net/patterns/patternworkshop.htm pattern writing workshops for software patterns]. The aim is to promote development and review of actual patterns, rather than papers describing patterns. Related events are also [http://vocamp.org/wiki/VoCampIbiza2009 VoCamps] for writing vocabularies for the Semantic Web.

== Topics ==
The main aim of the workshop is to discuss and collect best practices and experiences, hence submissions should focus on some notion of best practices. Original research papers and poster papers are invited to consider the following (non exhaustive) list of topics:

* Good practices of ontology design
* Good practices for Linked Data and related applications
* Good practices for hybridization of semantic web and NLP techniques
* Good Practices and Patterns of semantic social networks, semantic wikis, semantic blogs
* Good Practices of Semantic Web in general

* Ontology Design Patterns and Linked Data
* Ontology Patterns and Microformats
* Patterns for using different vocabularies together e.g. FOAF, SIOC, DC, etc.
* Web semantics from a pattern perspective

* Software patterns for semantic web applications
* Interaction patterns and the Semantic Web
* Pattern-based methodologies for Semantic Web ontologies and software engineering
* Application Profiles
* Domain specific applications based on patterns and successful stories

* Ontology design patterns (ODPs) for specific knowledge domains e.g. multimedia, fishery and agriculture, user profiling, business modeling, etc.
* Collaboration patterns in ontology design and engineering
* Correspondence patterns for ontology matching and integration
* Lexico-syntactic patterns
* Reasoning patterns (workflows made of reasoning steps for addressing specific goals)
* Processes and services - process patterns
* Re-engineering patterns for conceptual models, folksonomies, lexicons, thesauri
* Problem solving methods and patterns

* Tools support for pattern-based knowledge engineering
* Pattern-based ontology evaluation and selection
* Automatic ontology construction (ontology learning) based on patterns
* Contextual reasoning and patterns as context
* Knowledge patterns and knowledge re-engineering based on patterns
* Pattern-based information extraction

* Quality evaluation of patterns
* Benefits of ontology patterns and knowledge patterns

The poster category is particularly suitable for short research papers (e.g. work-in-progress or preliminary results) and for descriptions of software tools supporting the design, management, discovery, matching, or any other way of processing ontology patterns. A poster can also provide a high-level description of a research project that has ontology patterns as one of its topics (position paper).

===Patterns===
Pattern proposals for the “pattern writing” sessions will be collected through the [[Ontology_Design_Patterns_._org_(ODP) | ODP portal]], and templates for submission are provided for the following types of patterns (see general [[OPTypes | typology]] for explanation of the types):
* Content patterns
* Structural patterns: logical and architecture patterns
* Correspondence patterns: re-engineering and alignment patterns
For other types of patterns, or if the author wishes to elaborate on theoretical rather than practical aspects, a pattern description may be submitted as either a research paper or poster paper. A paper submission can be accompanied by a pattern submission, however the submissions will be reviewed separately.

|Score=1 - needs minor revision
|ReviewSummary=Path enumeration is a technique which is quite common in classification schemes. To support re-engineering of such schemes contributes to making them available for semantic applications, which makes the proposed ODP both very relevant and useful.

The basic idea of the pattern and the proposed process are good and require only minor improvements (see detailed comments). But the preconditions for using the pattern and its limitations should be expressed more clearly. Not all existing implementations of the path enumeration scheme are as clean as the UN standards. Path enumeration is not only used with the subClassOf semantics, but also for instanceOf relations. This is mentioned in the description, but should be made more explicit:
Please describe, which preconditions apply for using this pattern (for example: mutually exclusive concept groups, path constitutes unique identifier for concept groups, subClassOf relationship).
An option in this context would be to extend the proposed pattern for cases, when some of the current preconditions do not apply (e.g. other relationships than subClassOf).

Detailed comments:
- the first step in the process description should be re-phrased (unclear wording; what does key value mean in this context?)
- in the graphical representation: the start of a loop is represented in 2 different ways. Please check.
- in “process example” (Example section) you should use the same numbering of the process steps as in the process description. Furthermore, you should also include the first step “identify the classification scheme items” in the example

The pattern is suitable for presentation at WOP, but might not stimulate a long discussion as the proposed solution – in my opinion is not controversial.

== Welcome to the Workshop on Ontology Patterns - WOP2009 ==
This is the first edition in a series of yearly workshops addressing the emerging topic of ontology patterns as best practices, related to the [[Ontology_Design_Patterns_._org_(ODP) |''ontologydesignpatterns.org'']] initiative. Patterns need to be shared by a community in order to provide a common language and stimulate pattern usage and development. Hence, the aim of this workshop is twofold; both providing an arena for proposing and discussing good practices, patterns, pattern-based ontologies, systems etc., and broadening the pattern community that will develop its own “language” for discussing and describing relevant problems and their solutions.

The first workshop will be held in conjunction with [http://iswc2009.semanticweb.org/ ISWC], at a [http://iswc2009.semanticweb.org/wiki/index.php/Westfields_Conference_Center venue] in the Washington DC area (US), on October 25th 2009. It will be a full-day workshop consisting of three parts; paper presentations, posters, and “pattern writing” sessions. For the pattern writing sessions ontology design patterns will be submitted and reviewed at [[Ontology_Design_Patterns_._org_(ODP) |''ontologydesignpatterns.org'']], including the assignment of an advisor for each accepted pattern submission.

== Workshop Focus and Relevance ==
As interest in the Semantic Web increases and technologies for realizing the semantic web become more mature, the need for high-quality and reusable semantic web ontologies increases. To address the quality and reusability issues, different types of Ontology Design Patterns (ODPs) have emerged. Patterns can supply ontology designers with several kinds of benefits, including a direct link to requirements, reuse, guidance, and better communication. ODPs are well on their way to providing those benefits. ODPs have been [http://www.w3.org/2001/sw/BestPractices/OEP/ proposed by the W3C] and are currently being collected in various repositories, such as the [http://www.gong.manchester.ac.uk/odp/html/index.html catalogue maintained by the University of Manchester] and the ODP portal at [[Ontology_Design_Patterns_._org_(ODP) |ontologydesignpatterns.org]]. However, pattern catalogues are still small and do not cover all types of patterns and all domains. Semantic Web applications could also benefit from additional types of patterns, such as knowledge patterns and specialized software patterns for semantic applications. In addition, to achieve communication benefits, patterns need to be shared by a community in order to provide a common language for discussing and understanding modeling problems. The workshop can leverage the activities conducted in the ontologydesignpatterns.org initiative, and aims to use the portal as its main means of communication, e.g. for pattern submission, reviewing and discussions outside the workshop schedule.

Reuse has been an important research subject in ontology engineering for many years, and this is also true for the semantic web community. Patterns are an approach to knowledge reuse that has proved feasible and very profitable in many other areas such as software engineering and data modeling. During the past few years, patterns for semantic web ontologies and ontology-based applications have been introduced, and at this point in time we believe that the community would highly benefit from a series of workshops focusing on this particular topic. An earlier workshop, [http://www.research.ibm.com/people/w/welty/OPSW-05/ Ontology Patterns for the Semantic Web] , was arranged at ISWC2005, however at that time the community was considerably smaller. The focus then was on discussing reusable OWL and RDF ontologies addressing general open problems. The WOP series broadens this scope to include all patterns related to ontology design and knowledge engineering for the Semantic Web. This is in line with the successful [http://ekaw2008.inrialpes.fr/ EKAW2008] conference (with the sub-title Knowledge Patterns). Topics of this conference included ontology engineering patterns but also patterns for re-engineering of knowledge resources, process knowledge, social and cognitive aspects of semantics.

A workshop should be a practical and interaction-rich event, hence the workshop will have three parts: regular papers, posters, and “pattern writing”, with a focus on the latter. The inspiration for this model comes from the [http://hillside.net/patterns/patternworkshop.htm pattern writing workshops for software patterns]. The aim is to promote development and review of actual patterns, rather than papers describing patterns. Related events are also [http://vocamp.org/wiki/VoCampIbiza2009 VoCamps] for writing vocabularies for the Semantic Web.

== Topics ==
The main aim of the workshop is to discuss and collect best practices and experiences, hence submissions should focus on some notion of best practices. Original research papers and poster papers are invited to consider the following (non exhaustive) list of topics:

* Good practices of ontology design
* Good practices for Linked Data and related applications
* Good practices for hybridization of semantic web and NLP techniques
* Software patterns for semantic web applications
* Interaction patterns and the Semantic Web

* Good Practices and Patterns of semantic social networks, semantic wikis, semantic blogs
* Pattern-based methodologies for Semantic Web ontologies and software engineering

* Ontology Design Patterns and Linked Data
* Ontology Patterns and Microformats
* Application Profiles
* Patterns for using different vocabularies together e.g. FOAF, SIOC, DC, etc.
* Ontology design patterns (ODPs) for specific knowledge domains e.g. multimedia, fishery and agriculture, user profiling, business modeling, etc.

* Tools support for pattern-based knowledge engineering
* Collaboration patterns in ontology design and engineering
* Pattern-based ontology evaluation and selection
* Domain specific applications based on patterns and successful stories

* Correspondence patterns for ontology matching and integration
* Automatic ontology construction (ontology learning) based on patterns
* Lexico-syntactic patterns
* Reasoning patterns (workflows made of reasoning steps for addressing specific goals)
* Processes and services - process patterns
* Re-engineering patterns for conceptual models, folksonomies, lexicons, thesauri

* Contextual reasoning and patterns as context
* Knowledge patterns and knowledge re-engineering based on patterns
* Pattern-based information extraction
* Problem solving methods and patterns

* Quality evaluation of patterns
* Benefits of ontology patterns and knowledge patterns
* Web semantics from a pattern perspective

The poster category is particularly suitable for short research papers (e.g. work-in-progress or preliminary results) and for descriptions of software tools supporting the design, management, discovery, matching, or any other way of processing ontology patterns. A poster can also provide a high-level description of a research project that has ontology patterns as one of its topics.

Pattern proposals for the “pattern writing” sessions will be collected through the [[Ontology_Design_Patterns_._org_(ODP) | ODP portal]], and templates for submission are provided for the following types of patterns (see general [[OPTypes | typology]] for explanation of the types):
* Content patterns
* Structural patterns: logical and architecture patterns
* Correspondence patterns: re-engineering and alignment patterns
For other types of patterns, or if the author wishes to elaborate on theoretical rather than practical aspects, a pattern description may be submitted as either a research paper or poster paper.

WOP:2009

KurtSandkuhl:

== Welcome to WOP2009! ==
This is the first edition in a series of yearly workshops addressing the emerging topic of ontology patterns, related to the [[Ontology_Design_Patterns_._org_(ODP) |''ontologydesignpatterns.org'']] initiative. Patterns need to be shared by a community in order to provide a common language and stimulate pattern usage and development. Hence, the aim of this workshop is twofold; both providing an arena for proposing and discussing patterns, pattern-based ontologies, systems etc., and broadening the pattern community that will develop its own “language” for discussing and describing relevant problems and their solutions.

The first workshop will be held at ISWC on October 25th 2009. It will be a full-day workshop consisting of three parts; paper presentations, posters, and “pattern writing” sessions. For the pattern writing sessions ontology design patterns will be submitted and reviewed at [[Ontology_Design_Patterns_._org_(ODP) |''ontologydesignpatterns.org'']], including the assignment of an advisor for each accepted pattern submission.

== Workshop Focus and Relevance ==
As interest in the Semantic Web increases and technologies for realizing the semantic web become more mature, the need for high-quality and reusable semantic web ontologies increases. To address the quality and reusability issues, different types of Ontology Design Patterns (ODPs) have emerged. Patterns can supply ontology designers with several kinds of benefits, including a direct link to requirements, reuse, guidance, and better communication. ODPs are well on their way to providing those benefits. ODPs have been [http://www.w3.org/2001/sw/BestPractices/OEP/ proposed by the W3C] and are currently being collected in various repositories, such as the [http://www.gong.manchester.ac.uk/odp/html/index.html catalogue maintained by the University of Manchester] and the ODP portal at [[Ontology_Design_Patterns_._org_(ODP) |ontologydesignpatterns.org]]. However, pattern catalogues are still small and do not cover all types of patterns and all domains. Semantic Web applications could also benefit from additional types of patterns, such as knowledge patterns and specialized software patterns for semantic applications. In addition, to achieve communication benefits, patterns need to be shared by a community in order to provide a common language for discussing and understanding modeling problems. The workshop can leverage the activities conducted in the ontologydesignpatterns.org initiative, and aims to use the portal as its main means of communication, e.g. for pattern submission, reviewing and discussions outside the workshop schedule.

Reuse has been an important research subject in ontology engineering for many years, and this is also true for the semantic web community. Patterns are an approach to knowledge reuse that has proved feasible and very profitable in many other areas such as software engineering and data modeling. During the past few years, patterns for semantic web ontologies and ontology-based applications have been introduced, and at this point in time we believe that the community would highly benefit from a series of workshops focusing on this particular topic. An earlier workshop, [http://www.research.ibm.com/people/w/welty/OPSW-05/ Ontology Patterns for the Semantic Web] , was arranged at ISWC2005, however at this time the community was considerably smaller. The focus of that workshop was on discussing reusable OWL and RDF ontologies addressing general open problems.
