|
|
<p>
|
|
As in several other scientific domains, the use of social software (such as blogs or wikis) and social networking applications is now commonly accepted in the Health Care and Life Science (HCLS) research community, with services such as <a href="http://hypothesis.alzforum.org/swan/">the SWAN Alzheimer Knowledge Base</a>, <a href="http://www.myexperiment.org/">myExperiment</a>, <a href="http://www.wikiprofessional.org/">WikiProfessional Concept Web</a>, <a href="http://www.connotea.org/">Connotea</a> and <a href="http://network.nature.com/">Nature Networks</a>.
|
|
In general, however, these applications suffer from a lack of interoperability, and this makes the reuse of information a complex task.
|
|
The SIOC Ontology - Semantically-Interlinked Online Communities - aims to solve these issues and provides a comprehensive model to represent online communities and related user-generated content items thanks to Semantic Web technologies. This note describes the changes to the SIOC Core Ontology since its <a href="http://www.w3.org/Submission/2007/02/">W3C Member Submission</a> in June 2007, the SIOC Types Module, and their relevance in the Health Care and Life Sciences context.

<h3 id="intro_motivations">1.1. Motivations for the SIOC Project in Health Care and Life Sciences</h3>
|
|
|
|
<p>Social media is now a well-accepted paradigm, not only for
|
|
leisure-oriented Web 2.0 applications but also in scientific communities,
|
|
especially in the Health Care and Life Sciences context. Researchers
|
|
can share their experiments and opinions using weblogs, build knowledge
|
|
collaboratively through the use of wikis, use social networking tools to gather
|
|
information around topics and publications, etc., hence using social
|
|
media as a complement to traditional paper publications. Some popular social media tools for researchers include <a href="http://hypothesis.alzforum.org/swan/">the SWAN Alzheimer Knowledge Base</a>, <a href="http://www.myexperiment.org/">myExperiment</a>, <a href="http://www.wikiprofessional.org/">Wiki Professional</a>, and <a href="http://connotea.org/">Connotea</a>.
|
|
</p>
|
|
|
|
<p>However, social media services generally act as independent and
|
|
disconnected data silos that cannot communicate very efficiently with
|
|
each other. There are no bridges between them that could be used, for
|
|
example, to retrieve from a wiki a list of items about topics retrieved
|
|
from several weblogs. Moreover, sharing information between these
|
|
services is also an important issue: generally, when people upload some
|
|
content to a service, it can only be commented on (or sometimes only be
|
|
viewed) by people registered on that service.
|
|
</p>
|
|
|
|
<p>The SIOC Project (Semantically-Interlinked Online Communities) aims
|
|
to provide models and tools to achieve this goal of interoperability
|
|
between online communities and related user-generated content. It uses
|
|
Semantic Web technologies including a set of ontologies, tools and related
|
|
services. Complete information about SIOC can be found on the <a href="http://sioc-project.org/">SIOC Project</a> website as well as on the <a href="http://wiki.sioc-project.org/">SIOC Wiki</a>, and some background is given in the paper entitled "<a href="http://www.w3.org/2008/09/msnws/papers/sioc.html">SIOC: Content Exchange and Semantic Interoperability Between Social Networks</a>" from the W3C Workshop on the Future of Social Networking.
|
|
</p>
|
|
|
|
<p>
|
|
In particular in the context of the Health Care and Life Sciences community,
|
|
SIOC enables integration between different platforms and communities of
|
|
researchers that share information, experience and publications on
|
|
various topics.
|
|
By providing a common and machine-readable format for modeling
|
|
communities and their data via Semantic Web technologies, it also
|
|
permits advanced querying and browsing capabilities over this data, as
|
|
well as re-use in other contexts.
|
|
</p>
|
|
|
|
<h3 id="intro_organization">1.2. Organization of the SIOC Ontology</h3>
|
|
|
|
<p>The SIOC Ontology is the foundation of the SIOC Project. The various
|
|
tools and services from the project are based on this data model in
|
|
order to publish, exchange and consume data between social media
|
|
websites and applications.
|
|
This ontology is defined in two main parts:
|
|
</p>
|
|
<ul>
|
|
<li>The SIOC Core Ontology, available at <a href="http://rdfs.org/sioc/ns">http://rdfs.org/sioc/ns</a></li>
|
|
<li>The SIOC Ontology Modules</li>
|
|
</ul>
|
|
<p>Four modules for SIOC have been designed so far, a fifth one being the
|
|
module defining mappings with the SWAN ontology, described in detail in
|
|
[<a href="#ref-swansioc">SWAN-SIOC</a>].
|
|
The four other modules are defined as follows:
|
|
</p>
|
|
<ul>
|
|
<li>The Types Module: <a href="http://rdfs.org/sioc/types">http://rdfs.org/sioc/types</a>.
|
|
This module provides advanced content types to be used when defining
|
|
user-generated content from online communities. It will be described in
|
|
detail in a <a href="#sioctypes">following section</a> of this document</li>
|
|
<li>The Access Module: <a href="http://rdfs.org/sioc/access">http://rdfs.org/sioc/access</a>. This module provides the notions of <a href="http://rdfs.org/sioc/types#Role">Role</a> and <a href="http://rdfs.org/sioc/types#Permission">Permission</a> as a simple way to define access rights and permissions in online communities.</li>
|
|
<li>The Services Module: <a href="http://rdfs.org/sioc/services">http://rdfs.org/sioc/services</a>. This module provides a way to represent Web services related to online communities (APIs, SPARQL endpoints, etc.).</li>
|
|
<li>The Argumentation Module: <a href="http://rdfs.org/sioc/argument">http://rdfs.org/sioc/argument</a>. This module provides a way to represent simple argumentative discussions in online communities.</li>
|
|
</ul>

<h2 id="sioc">2. The SIOC Core Ontology</h2>
|
|
|
|
<h3 id="sioc_core">2.1. Overview of the the SIOC Core Ontology</h3>
|
|
|
|
<p>
|
|
Since further details about the SIOC Core Ontology itself can be found on its related Member Submission [<a href="#ref-siocsubmission">SIOC-MemberSubmission</a>] and on its current live specification [<a href="#ref-siocspec">SIOC-Specification</a>], we will simply give a brief overview of the model in this note.
|
|
</p>
|
|
|
|
<p>
|
|
The SIOC Core Ontology [<a href="#ref-siocspec">SIOC-Specification</a>] currently consists of 11 classes and about 50 properties.
|
|
The following schema represents the main classes and properties of the SIOC Core Ontology.
|
|
Two classes are not shown here: the <a href="http://rdfs.org/sioc/ns#Community">sioc:Community</a> class, that aims at representing a collection of people, services and content around a particular topic of interest, and the <a href="http://rdfs.org/sioc/ns#Thread">sioc:Thread</a> class, a subclass of <a href="http://rdfs.org/sioc/ns#Container">sioc:Container</a> dedicated to representing threaded discussions, such as those that occur on bulletin boards.

</p>
|
|
</div>
|
|
|
|
<p>
|
|
The SIOC Ontology also has strong ties with other vocabularies, such as FOAF [<a href="#ref-foaf">FOAF</a>], SKOS [<a href="#ref-skos">SKOS</a>] and Dublin Core [<a href="#ref-dc">DublinCore</a>].
|
|
The [<a href="#ref-siocmappings">SIOC-Mappings</a>]
|
|
document provides an overview of the different mappings between SIOC
|
|
and these models. As an example, the following source code represents
|
|
how an item on a web site can be modeled with SIOC and these related
|
|
vocabularies using N3 notation.

<h3 id="sioc_changes">2.2. Changes Since the Member Submission</h3>
|
|
|
|
<p>
|
|
Several changes have happened since the SIOC Core Ontology was published as a <a href="http://www.w3.org/Submission/2007/SUBM-sioc-spec-20070612/">W3C Member Submission</a>.
|
|
Most
|
|
enhancements have been based on discussions that happened on the
|
|
SIOC developers mailing list based on implementation needs and experience.
|
|
While no new classes have been introduced (in order to keep the model
|
|
lightweight), the following changes have been made to the SIOC Core
|
|
Ontology's classes and properties (changes are ordered by alphabetical
|
|
order for properties and classes):
|
|
</p>
|
|
|
|
<dl>
|
|
|
|
<dt>Adding new properties</dt>
|
|
<dd>The following properties have been added:
|
|
<ul>
|
|
<li><a href="http://rdfs.org/sioc/spec/#term_has_discussion">sioc:has_discussion</a>:
|
|
The has_discussion property links any sioc:Item to a related
|
|
discussion. The discussion can be anything, for example, a sioc:Forum,
|
|
a sioct:WikiArticle or simply a foaf:Document.</li>
|
|
<li><a href="http://rdfs.org/sioc/spec/#term_earlier_version">sioc:earlier_version</a>:
|
|
The earlier_version property links any sioc:Item to any earlier (i.e.
|
|
older) version. This is a transitive property. The related
|
|
non-transitive property that links any sioc:Item to its immediately
|
|
older version is previous_version. previous_version is a subproperty of
|
|
earlier_version.</li>
|
|
<li><a href="http://rdfs.org/sioc/spec/#term_later_version">sioc:later_version</a>:
|
|
The later_version property links any sioc:Item to any later (i.e.
|
|
newer) version. This is a transitive property. The related
|
|
non-transitive property, that links any sioc:Item to its immediately
|
|
newer version is next_version. next_version is a subproperty of
|
|
later_version.</li>
|
|
<li><a href="http://rdfs.org/sioc/spec/#term_latest_version">sioc:latest_version</a>:
|
|
The latest_version property links a sioc:Item to its latest version.
|
|
This can be used to link a previous version of an item (e.g. a wiki
|
|
page) to its latest version.</li>
|
|
<li><a href="http://rdfs.org/sioc/spec/#term_follows">sioc:follows</a>: Indicates that one User follows another User (e.g. for microblog posts or other content item updates).</li>

<h2 id="types">3. The SIOC Types Module</h2>
|
|
|
|
<h3 id="types_aims">3.1. Aims of the Types Module</h3>
|
|
|
|
<p>While the SIOC Core Ontology defines a set of classes that can be
|
|
used to represent user-generated content, both in terms of items (<a href="http://rdfs.org/sioc/ns#Post">sioc:Post</a> and <a href="http://rdfs.org/sioc/ns#Item">sioc:Item</a>) and containers (<a href="http://rdfs.org/sioc/ns#Forum">sioc:Forum</a> and <a href="http://rdfs.org/sioc/ns#Container">sioc:Container</a>), these may still not be fine-grained enough for some knowledge representation purposes.
|
|
For example, using the <a href="http://rdfs.org/sioc/ns#Item">sioc:Item</a> class does not differentiate between a blog post, a wiki page or a post on a bulletin board.
|
|
In a similar way, using <a href="http://rdfs.org/sioc/ns#Container">sioc:Container</a> does not provide a way to differentiate (when querying information) between a weblog, a wiki, or a photo gallery.
|
|
</p>
|
|
|
|
<p>
|
|
In order to provide more fine-grained modeling of user-generated
|
|
content, the SIOC Types Module defines a set of classes that extend the
|
|
main classes of the SIOC Core Ontology.
|
|
The following figure represents how both a wiki and a wiki article can
|
|
be represented using the SIOC Types Module, respectively using the <a href="http://rdfs.org/sioc/types#Wiki">sioct:Wiki</a> and the <a href="http://rdfs.org/sioc/types#WikiArticle">sioct:WikiArticle</a> classes, defined respectively as subclasses of <a href="http://rdfs.org/sioc/ns#Forum">sioc:Forum</a> and <a href="http://rdfs.org/sioc/ns#Post">sioc:Post</a>, themselves being defined as subclasses of <a href="http://rdfs.org/sioc/ns#Container">sioc:Container</a> and <a href="http://rdfs.org/sioc/ns#Item">sioc:Item</a>.

<h3 id="types_classes">3.2. Classes in the Types Module and mappings with existing vocabularies</h3>
|

<p>
|
|
This section provides a complete list of the different classes defined
|
|
in the Types Module, as well as their mappings with related classes in
|
|
the SIOC Core Ontology.
|
|
</p>
|
|
|
|
<h4 id="types_containers">3.2.1. Containers and forums</h4>
|
|
|
|
<p>The following lists introduce the various containers and forums
|
|
introduced in the SIOC Types Module.
|
|
It also presents for each Container and Forum the related items that could be
|
|
contained therein.
|
|
As one can see, some items are defined within the SIOC namespace (hence
|
|
being described in the next section), while some of them are existing
|
|
concepts from different vocabularies.
|
|
It is important to mention that there are no constraints in the
|
|
ontology so that these relationships between container and items are
|
|
informative only and not subject to any kind of reasoning at the
|
|
moment.

In addition, the module introduces the three following classes (as subclasses of <a href="http://rdfs.org/sioc/ns#Post">sioc:Post</a>) to model questions and answers in online communities:
|
|
</p>
|
|
|
|
<ul>
|
|
<li><a href="http://rdfs.org/sioc/types#Question">sioct:Question</a>: A post that asks a question.</li>
|
|
<li><a href="http://rdfs.org/sioc/types#Answer">sioct:Answer</a>: A post that provides an answer in reply to a question.</li>
|
|
<li><a href="http://rdfs.org/sioc/types#BestAnswer">sioct:BestAnswer</a>: A post that is the best answer to a question, as chosen by the user who asked the question or as voted by a community of users.</li>
|
|
</ul>
|
|
|
|
<p>Finally, in order to represent the topics and tags that can be
|
|
assigned to such items, the Types Module introduces these two classes:
|
|
</p>
|
|
|
|
<ul>
|
|
<li><a href="http://rdfs.org/sioc/types#Category">Category</a>:
|
|
Category is used on the object of sioc:topic to indicate that this
|
|
resource is a category on a site. This class is used in order to define
|
|
categories that can be assigned, e.g. to a blog post or wiki page, and
|
|
generally pre-defined by administrators of the service. <a href="http://rdfs.org/sioc/types#Category">sioct:Category</a> is a subclass of <a href="http://www.w3.org/2008/05/skos#Concept">skos:Concept</a>, hence categories can be ordered hierarchically.</li>
|
|
<li><a href="http://rdfs.org/sioc/types#Tag">Tag</a>:
|
|
Tag is used on the object of sioc:topic to indicate that this resource
|
|
is a tag on a site. This class is used in order to represent free-text
|
|
tags, but assign them a particular URI. For more advanced tagging
|
|
capabilities, models such as the Tag Ontology [<a href="#ref-tagong">TagOntology</a>], [<a href="#ref-scot">SCOT</a>], [<a href="#ref-moat">MOAT</a>] or [<a href="#ref-ctag">CommonTag</a>] can be considered.</li>
|
|
</ul>
|
|

<h3 id="types_example">3.3. Example of RDF data using the SIOC Types Module</h3>
|

|
|
<p>
|
|
The following example extends <a href="#sioc-ex-code">the previous one</a>, using the Types module to model more precisely the different objects that have been created.
|
|
It uses <a href="http://rdfs.org/sioc/types#BlogPost">sioct:BlogPost</a> (instead of the more generic <a href="http://rdfs.org/sioc/ns#Post">sioc:Post</a>), <a href="http://rdfs.org/sioc/types#Weblog">sioct:Weblog</a> (a subclass of <a href="http://rdfs.org/sioc/ns#Container">sioc:Container</a>), <a href="http://rdfs.org/sioc/types#Comment">sioct:Comment</a> and <a href="http://rdfs.org/sioc/types#Category">sioct:Category</a>.
|
|
As one can see, it does not imply any other changes, neither in terms of properties nor mappings with other vocabularies.

<h2 id="usecases">4. Use cases for SIOC in HCLS</h2>
|
|
|
|
<h3 id="usecases1">4.1. Integrating information from Web 2.0 services in a pharmaceutical company</h3>
|
|
|
|
<p>ACME Pharma uses various blogs, wikis and microblogging applications
|
|
to enable communication and knowledge sharing between its different
|
|
research teams.
|
|
However, since various tools have been implemented and deployed, based on
|
|
the different needs of the internal communities, it is difficult to query and
|
|
retrieve information from all of these systems.
|
|
By providing SIOC exports for all of this data, and through the use of existing
|
|
applications / APIs [<a href="#ref-siocapps">SIOC-Applications</a>]
|
|
and a single RDF repository to store this data, it is then possible to
|
|
query the data from a single place using uniform SPARQL queries.
|
|
Moreover, these queries can take advantage of the SIOC Types module,
|
|
for example, to retrieve only instances of <a href="http://rdfs.org/sioc/types#WikiArticle">sioct:WikiArticle</a> or <a href="http://rdfs.org/sioc/types#BlogPost">sioct:BlogPost</a>, depending on the kind of information that is to be retrieved.
|
|
This use case is similar to what is described in [<a href="#sweo-edf">SWEO-EDF</a>]
|
|
and can be implemented with currently-available Semantic Web
|
|
technologies, especially the ones described in this document, i.e. SIOC
|
|
and its Types Module.
|
|
</p>
|
|
|
|
<h3 id="usecases2">4.2 Sharing patient information on the Web</h3>
|
|
|
|
<p>Alice and Bob suffer from diabetes, and often blog about research
|
|
findings, the drugs they are using, their treatments, etc. As a matter
|
|
of transparency and in order to share their experiences with other
|
|
patients, as well as with their doctors, they provide SIOC exports of
|
|
their blog data.
|
|
Each conversation is therefore available as open and machine-readable
|
|
information.
|
|
Thanks to this openness, this data can be consumed by pharmaceutical
|
|
companies via existing SIOC tools [<a href="#ref-siocapps">SIOC-Applications</a>] so that they can track discussions about the drugs that people are using, and provide feedback if needed.
|
|
Thanks to the use of the SIOC Types Module, people consuming the data can distinguish the original blogged information (<a href="http://rdfs.org/sioc/types#BlogPost">sioct:BlogPost</a>) from the comments (<a href="http://rdfs.org/sioc/types#Comment">sioct:Comment</a>).
|
|
It is worth noting that, for each blog post, Alice and Bob have the
|
|
ability - to ensure privacy - to not export it as SIOC data.
|
|
</p>
|
|
|
|
<h2 id="conclusion">5. Conclusion</h2>
|
|
|
|
<p>In this note, we described the changes to the SIOC Ontology since
|
|
its Member Submission as well as the SIOC Types Module. In particular, we
|
|
focused on the use of SIOC in the context of communities of researchers
|
|
and scientists from the Health Care and Life Science domain. As shown
|
|
in the use cases section, SIOC can be efficiently deployed as a means
|
|
to integrate information from various applications and communities in a
|
|
unified, machine-readable and comprehensive way, offering new
|
|
possibilities in terms of scientific knowledge management.
