LinkHub: a Semantic Web system that facilitates cross-database queries and information retrieval in proteomics.

AK Smith — 2007-06-07T03:04:30-00:00

BMC Bioinformatics, Vol. 8 Suppl 3 (2007)

BACKGROUND: A key abstraction in representing proteomics knowledge is the notion of unique identifiers for individual entities (e.g. proteins) and the massive graph of relationships among them. These relationships are sometimes simple (e.g. synonyms) but are often more complex (e.g. one-to-many relationships in protein family membership). RESULTS: We have built a software system called LinkHub using Semantic Web RDF that manages the graph of identifier relationships and allows exploration with a variety of interfaces. For efficiency, we also provide relational-database access and translation between the relational and RDF versions. LinkHub is practically useful in creating small, local hubs on common topics and then connecting these to major portals in a federated architecture; we have used LinkHub to establish such a relationship between UniProt and the North East Structural Genomics Consortium. LinkHub also facilitates queries and access to information and documents related to identifiers spread across multiple databases, acting as "connecting glue" between different identifier spaces. We demonstrate this with example queries discovering "interologs" of yeast protein interactions in the worm and exploring the relationship between gene essentiality and pseudogene content. We also show how "protein family based" retrieval of documents can be achieved. LinkHub is available at hub.gersteinlab.org and hub.nesg.org with supplement, database models and full-source code. CONCLUSION: LinkHub leverages Semantic Web standards-based integrated data to provide novel information retrieval to identifier-related documents through relational graph queries, simplifies and manages connections to major hubs such as UniProt, and provides useful interactive and query interfaces for exploring the integrated data.

Automatic ontology-based knowledge extraction from Web documents

H Alani — 2006-09-18T14:47:09-00:00

Intelligent Systems, IEEE [see also IEEE Intelligent Systems and Their Applications], Vol. 18, No. 1. (2003), pp. 14-21.

To bring the Semantic Web to life and provide advanced knowledge services, we need efficient ways to access and extract knowledge from Web documents. Although Web page annotations could facilitate such knowledge gathering, annotations are rare and will probably never be rich or detailed enough to cover all the knowledge these documents contain. Manual annotation is impractical and unscalable, and automatic annotation tools remain largely undeveloped. Specialized knowledge services therefore require tools that can search and extract specific knowledge directly from unstructured text on the Web, guided by an ontology that details what type of knowledge to harvest. An ontology uses concepts and relations to classify domain knowledge. Other researchers have used ontologies to support knowledge extraction, but few have explored their full potential in this domain. The paper considers the Artequakt project which links a knowledge extraction tool with an ontology to achieve continuous knowledge support and guide information extraction. The extraction tool searches online documents and extracts knowledge that matches the given classification structure. It provides this knowledge in a machine-readable format that will be automatically maintained in a knowledge base (KB). Knowledge extraction is further enhanced using a lexicon-based term expansion mechanism that provides extended ontology terminology.

Information retrieval and knowledge discovery utilising a biomedical Semantic Web.

S Mukherjea — 2005-11-23T13:22:18-00:00

Brief Bioinform, Vol. 6, No. 3. (September 2005), pp. 252-262.

Although various ontologies and knowledge sources have been developed in recent years to facilitate biomedical research, it is difficult to assimilate information from multiple knowledge sources. To enable researchers to easily gain understanding of a biomedical concept, a biomedical Semantic Web that seamlessly integrates knowledge from biomedical ontologies, publications and patents would be very helpful. In this paper, current research efforts in representing biomedical knowledge in Semantic Web languages are surveyed. Techniques are presented for information retrieval and knowledge discovery from the Semantic Web that extend traditional keyword search and database querying techniques. Finally, some of the challenges that have to be addressed to make the vision of a biomedical Semantic Web a reality are discussed.

Delivering Semantic Web Services

M Paolucci — 2005-11-03T22:59:06-00:00

(2002)

The growing infrastructure for Web Services assumes a "programmer in the loop" that hardcodes the connections between Web Services and directly programs Web Service composition. Emerging technology based on DAML-S and the Semantic Web allows Web Services to connect and transact automatically with minimal or no intervention from programmers. In this paper we discuss the problems related with autonomous Web Services, and how DAMLS provides the information to solve them. Furthermore, we describe...

The Semantic Web: the roles of XML and RDF

S Decker — 2005-10-19T17:37:36-00:00

Internet Computing, IEEE, Vol. 4, No. 5. (2000), pp. 63-73.

XML and RDF are the current standards for establishing semantic interoperability on the Web, but XML addresses only document structure. RDF better facilitates interoperation because it provides a data model that can be extended to address sophisticated ontology representation techniques. We explain the role of ontologies in the architecture of the Semantic Web. We then briefly summarize key elements of XML and RDF, showing why using XML as a tool for semantic interoperability will be ineffective in the long run. We argue that a further representation and inference layer is needed on top of the Web's current layers, and to establish such a layer, we propose a general method for encoding ontology representation languages into RDF/RDF schema. We illustrate the extension method by applying it to Ontology Interchange Language, an ontology representation and inference language

Can OWL and Logic Programming Live Together Happily Ever After?

Boris Motik — 2008-02-06T22:19:04-00:00

The Semantic Web - ISWC 2006 (2006), pp. 501-514.

Logic programming (LP) is often seen as a way to overcome several shortcomings of the Web Ontology Language (OWL), such as the inability to model integrity constraints or perform closed-world querying. However, the open-world semantics of OWL seems to be fundamentally incompatible with the closed-world semantics of LP. This has sparked a heated debate in the Semantic Web community, resulting in proposals for alternative ontology languages based entirely on logic programming. To help resolving this debate, we investigate the practical use cases which seem to be addressed by logic programming. In fact, many of these requirements have already been addressed outside the Semantic Web. By drawing inspiration from these existing formalisms, we present a novel logic of hybrid MKNF knowledge bases, which seamlessly integrates OWL with LP. We are thus capable of addressing the identified use cases without a radical change in the architecture of the Semantic Web.

Ontology Merging for Federated Ontologies on the Semantic Web

G Stumme — 2007-10-04T19:24:10-00:00

(2001)

One of the core challenges for the Semantic Web is the aspect of decentralization. Local structures can be modeled by ontologies. However, in order to support global communication and knowledge exchange, mechanisms have to be developed for integrating the local systems. We adopt the database approach of autonomous federated database systems and consider an architecture for federated ontologies for the Semantic Web as starting point of our work.

On deep annotation

Siegfried Handschuh — 2006-06-21T14:49:49-00:00

(2003), pp. 431-438.

The success of the Semantic Web crucially depends on the easy creation, integration and use of semantic data. For this purpose, we consider an integration scenario that defies core assumptions of current metadata construction methods. We describe a framework of metadata creation when web pages are generated from a database and the database owner is cooperatively participating in the Semantic Web. This leads us to the definition of ontology mapping rules by manual semantic annotation and the usage of the mapping rules and of web services for semantic queries. In order to create metadata, the framework combines the presentation layer with the data description layer -- in contrast to "conventional" annotation, which remains at the presentation layer. Therefore, we refer to the framework as deep annotation 1.We consider deep annotation as particularly valid because, (i), web pages generated from databases outnumber static web pages, (ii), annotation of web pages may be a very intuitive way to create semantic data from a database and, (iii), data from databases should not be materialized as RDF files, it should remain where it can be handled most efficiently -- in its databases.

Wikipedia and the Semantic Web - The Missing Links

Markus Krötzsch — 2006-06-22T17:13:10-00:00

Wikipedia is the biggest collaboratively created source of encyclopaedic knowledge. Growing beyond the borders of any traditional encyclopaedia, it is facing new problems of knowledge management: The current excessive usage of article lists and categories witnesses the fact that 19th century content organization technologies like inter-article references and indices are no longer su#cient for today's needs.

Contexts for the Semantic Web

R Guha — 2005-10-29T11:05:12-00:00

Vol. 3298 (November 2004)

A central theme of the semantic web is that programs should be able to easily aggregate data from di#erent sources. Unfortunately, even if two sites provide their data using the same data model and vocabulary, subtle differences in their use of terms and in the assumptions they make pose challenges for aggregation. Experiences with the TAP project reveal some of the phenomena that pose obstacles to a simplistic model of aggregation. Similar experiences have been reported by AI projects such as...

Towards semantic web mining

B Berendt — 2005-06-16T09:59:28-00:00

(2002)

Semantic Web Mining aims at combining the two fast-developing research areas Semantic Web and Web Mining. The idea is to improve, on the one hand, the results of Web Mining by exploiting the new semantic structures in the Web; and to make use of Web Mining, on the other hand, for building up the Semantic Web. This paper gives an overview of where the two areas meet today, and sketches ways of how a closer integration could be profitable.

A Coalgebraic Description of Web Interactions

Daniela Cancila — 2008-06-01T09:23:14-00:00

Theoretical Computer Science (2003), pp. 271-283.

We introduce a coalgebraic description of static web sites, whereby pages are modeled by their links to other pages together with some extra information. This information can be either related to the contents or to the presentation or to the architecture of the page, etc., and its granularity can vary. This coalgebraic model provides a formal framework for the analysis of the design of single web sites and for the comparison of different sites. We give two alternative coalgebraic accounts of user visits to a web site, as they arise by extracting the information contained in the log file of the web server. The first one is defined in terms of the notion of injective simulation, the latter in terms of an appropriate lax morphism in Rel. These notions provide formal descriptions of user behaviours and can suggest formal tools for the study of the usability of a site.

Accelerating Socio-Technological Evolution: from ephemeralization and stigmergy to the global brain

Francis Heylighen — 2007-04-18T15:02:06-00:00

(1 Mar 2007)

Evolution is presented as a trial-and-error process that produces a progressive accumulation of knowledge. At the level of technology, this leads to ephemeralization, i.e. ever increasing productivity, or decreasing of the friction that normally dissipates resources. As a result, flows of matter, energy and information circulate ever more easily across the planet. This global connectivity increases the interactions between agents, and thus the possibilities for conflict. However, evolutionary progress also reduces social friction, via the creation of institutions. The emergence of such "mediators" is facilitated by stigmergy: the unintended collaboration between agents resulting from their actions on a shared environment. The Internet is a near ideal medium for stigmergic interaction. Quantitative stigmergy allows the web to learn from the activities of its users, thus becoming ever better at helping them to answer their queries. Qualitative stigmergy stimulates agents to collectively develop novel knowledge. Both mechanisms have direct analogues in the functioning of the human brain. This leads us to envision the future, super-intelligent web as a "global brain" for humanity. The feedback between social and technological advances leads to an extreme acceleration of innovation. An extrapolation of the corresponding hyperbolic growth model would forecast a singularity around 2040. This can be interpreted as the evolutionary transition to the Global Brain regime.

The web is moving from being a collection of pages toward a collection of services that interoperate through the Internet. A fundamental step toward this interoperation is the ability of automatically locating services on the bases of the functionalities that they provide. Such a functionality would allow services to locate each other and automatically interoperate. Location of web services is inherently a semantic problem, because it has to abstract fi'om the superficial differences between...

Biosemiotics and Biophysics — the fundamental approaches to the study of life

Kalevi Kull — 2007-10-18T13:35:19-00:00

Introduction to Biosemiotics (2007), pp. 167-177.

The importance, scope, and goals of semiotics can be compared to the ones of physics. These represent two principal ways of approaching the world scientifically. Physics is a study of quantities, whereas semiotics is a study of diversity. Physics is about natural laws, while semiotics is about code processes. Semiotic models can describe features that are beyond the reach of physical models due to the more restricted methodological requirements of the latter. The “measuring devices” of semiotics are alive — which is a sine qua non for the presence of meanings. Thus, the two principal ways to scientifically approach living systems are biophysics and biosemiotics. Accordingly, semiotic (including biosemiotic) systems can be studied both physically (e.g., using statistical methods) and semiotically (e.g., focusing on the uniqueness of the system). The principle of code plurality as a generalization of the code duality principle is formulated

. Because different applications and different communities require different features, the semantic web might have to face the heterogeneity of the languages for expressing knowledge. Yet, it will be necessary for many applications to use knowledge coming from different sources. In such a context, ensuring the correct understanding of imported knowledge on a semantic ground is very important. We present here an infrastructure based on the notions of transformations from one language to...

The emergent Semantic Web community needs a common infrastructure for testing the scalability and quality of new techniques and software which use machine processable data. Since ontologies are a centerpiece of most approaches , we believe that for an accurate evaluation of tools for quality, scalability and performance, the research community needs a freely available ontology with a large description base. If the use of tools is to be for advanced semantic applications, such as those in...
