The proposed personalization technique separates data collection and user profiling from the information system whose contents and indexed documents are being searched for, i.e. the search engines, and uses social bookmarking and tagging to re-rank web search results. It is independent of the search engine being used, so users are free to choose the one they prefer, even if their favorite search engine does not natively support personalization. We show how to design and implement such a system in practice and investigate its feasibility and usefulness with large sets of real-word data and a user study.http://www.bibsonomy.org/bibtex/2bc1ab4d450673d892a7b7edbbae635bf/ontomanontoman2007-11-12T10:43:18+01:00Network natural_language_processing network social web <span class="authorEditorList"><a href="/author/Geleijnse">Gijs Geleijnse</a>, and <a href="/author/Korst">Jan Korst</a> </span><em>Proceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference ISWC/ASWC2007, Busan, South Korea, </em><em>volume 4825 of LNCS, </em><em>page 155--168. </em><em>Berlin, Heidelberg, </em><em>Springer Verlag, </em>(<em>November 2007</em>)Mon Nov 12 10:43:18 CET 2007Berlin, HeidelbergProceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference (ISWC/ASWC2007), Busan, South Koreahttp://data.semanticweb.org/conference/iswc-aswc/2007/proceedingsNovember155--168LNCSCreating a Dead Poets Society: Extracting a Social Network of Historical Persons from the Web48252007Network natural_language_processing network social web We present a simple method to extract information from search engine snippets.

An important example of this paradigm can be found in the area of Ontology Matching, where new algorithms, which derive mappings from an exploration of multiple and heterogeneous online ontologies, have been proposed. While these algorithms exhibit very good performance, they rely on merely syntactical techniques to anchor the terms to be matched to those found on the Semantic Web. As a result, their precision can be affected by ambiguous words. In this paper, we aim to solve these problems by introducing techniques from Word Sense Disambiguation, which validate the mappings by exploring the semantics of the ontological terms involved in the matching process. Specifically we discuss how two techniques, which exploit the ontological context of the matched and anchor terms, and the information provided by WordNet, can be used to filter out mappings resulting from the incorrect anchoring of ambiguous terms. Our experiments show that each of the proposed disambiguation techniques, and even more their combination, can lead to an important increase in precision, without having too negative an impact on recall.http://www.bibsonomy.org/bibtex/2bfada9455439a56ce485c83fbc790e16/iswc2007iswc20072007-11-07T19:18:42+01:002007 iswc semantic web widget workshop_first <span class="authorEditorList"><a href="/author/Mäkelä">Eetu Mäkelä</a>, <a href="/author/Viljanen">Kim Viljanen</a>, <a href="/author/Alm">Olli Alm</a>, <a href="/author/Tuominen">Jouni Tuominen</a>, <a href="/author/Valkeapää">Onni Valkeapää</a>, <a href="/author/Kauppinen">Tomi Kauppinen</a>, <a href="/author/Kurki">Jussi Kurki</a>, <a href="/author/Sinkkilä">Reetta Sinkkilä</a>, <a href="/author/Känsälä">Teppo Känsälä</a>, <a href="/author/Lindroos">Robin Lindroos</a>, <a href="/author/Suominen">Osma Suominen</a>, <a href="/author/Ruotsalo">Tuukka Ruotsalo</a>, and <a href="/author/Hyvönen">Eero Hyvönen</a> </span><em>Proceedings of the Workshop on the First Industrial Results of Semantic Technologies FIRST2007 at ISWC/ASWC2007, Busan, South Korea, </em>(<em>November 2007</em>)Wed Nov 07 19:18:42 CET 2007Proceedings of the Workshop on the First Industrial Results of Semantic Technologies (FIRST2007) at ISWC/ASWC2007, Busan, South Koreahttp://data.semanticweb.org/workshop/first/2007/proceedingsNovemberEnabling the Semantic Web with Ready-to-Use Web Widgets20072007 iswc semantic web widget workshop_first A lot of functionality is needed when an application, such as a museum cataloguing system, is extended with semantic capabilities, for example ontological indexing functionality or multi-facet search. To avoid duplicate work and to enable easy and cost-efficient integration of information systems with the Semantic Web, we propose a web widget approach. Here, data sources are combined with functionality into ready-to-use software components that allow adding semantic functionality to systems with just a few lines of code. As a proof of the concept, we present a collection of general semantic web widgets and case applications that use them, such as the ontology server ONKI, the annotation editor SAHA and the culture portal CultureSampo.http://www.bibsonomy.org/bibtex/2fe7ac4a6c225a91fbab806a92a51cb97/iswc2007iswc20072007-11-07T19:13:58+01:002007 evaluation human-computer_interaction information_extraction interface iswc language natural natural_language_processing research_10 semantic semantic_web web <span class="authorEditorList"><a href="/author/Kaufmann">Esther Kaufmann</a>, and <a href="/author/Bernstein">Abraham Bernstein</a> </span><em>Proceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference ISWC/ASWC2007, Busan, South Korea, </em><em>volume 4825 of LNCS, </em><em>page 281-294. </em><em>Berlin, Heidelberg, </em><em>Springer Verlag, </em>(<em>November 2007</em>)Wed Nov 07 19:13:58 CET 2007Berlin, HeidelbergProceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference (ISWC/ASWC2007), Busan, South Koreahttp://data.semanticweb.org/conference/iswc-aswc/2007/proceedingsNovember281-294LNCSHow Useful are Natural Language Interfaces to the Semantic Web for Casual End-users?482520072007 evaluation human-computer_interaction information_extraction interface iswc language natural natural_language_processing research_10 semantic semantic_web web Natural language interfaces offer end-users a familiar and convenient option for querying ontology-based knowledge bases. Several studies have shown that they can achieve high retrieval performance as well as domain independence. This paper focuses on usability and investigates if NLIs are useful from an end-user's point of view. To that end, we introduce four interfaces each allowing a different query language and present a usability study benchmarking these interfaces. The results of the study reveal a clear preference for full sentences as query language and confirm that NLIs are useful for querying Semantic Web data.http://www.bibsonomy.org/bibtex/29da052694a4d63d8fc5048c77d67fabd/iswc2007iswc20072007-11-07T19:13:58+01:002007 adaptivity doctoral_consortium iswc semantic web <span class="authorEditorList"><a href="/author/Reinecke">Katharina Reinecke</a> </span><em>Proceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference ISWC/ASWC2007, Busan, South Korea, </em><em>volume 4825 of LNCS, </em><em>page 940--944. </em><em>Berlin, Heidelberg, </em><em>Springer Verlag, </em>(<em>November 2007</em>)Wed Nov 07 19:13:58 CET 2007Berlin, HeidelbergProceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference (ISWC/ASWC2007), Busan, South Koreahttp://data.semanticweb.org/conference/iswc-aswc/2007/proceedingsNovember940--944LNCSCultural Adaptivity for the Semantic Web482520072007 adaptivity doctoral_consortium iswc semantic web Our research explores the possibilities for factoring culture into user models, working towards cultural adaptivity in the Semantic Web.

For the large amount of available Web services that can be expected in real-world settings, the computational costs of automated discovery based on semantic matchmaking become important. To make a discovery engine a reliable software component, we must thus aim at minimizing both the mean and the variance of the duration of the discovery task. For this, we present an extension for discovery engines in SWS environments that exploits structural knowledge and previous discovery results for reducing the search space of consequent discovery operations. Our prototype implementation shows significant improvements when applied to the Stanford SWS Challenge scenario and dataset.http://www.bibsonomy.org/bibtex/25af761051f5ee7543ac1606fbd91ea96/iswc2007iswc20072007-11-07T19:13:58+01:002007 approach fundamentals isparql iswc research_03 semantic task triple virtual web <span class="authorEditorList"><a href="/author/Kiefer">Christoph Kiefer</a>, <a href="/author/Bernstein">Abraham Bernstein</a>, and <a href="/author/Stocker">Markus Stocker</a> </span><em>Proceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference ISWC/ASWC2007, Busan, South Korea, </em><em>volume 4825 of LNCS, </em><em>page 295--308. </em><em>Berlin, Heidelberg, </em><em>Springer Verlag, </em>(<em>November 2007</em>)Wed Nov 07 19:13:58 CET 2007Berlin, HeidelbergProceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference (ISWC/ASWC2007), Busan, South Koreahttp://data.semanticweb.org/conference/iswc-aswc/2007/proceedingsNovember295--308LNCSThe Fundamentals of iSPARQL - A Virtual Triple Approach For Similarity-Based Semantic Web Tasks482520072007 approach fundamentals isparql iswc research_03 semantic task triple virtual web This research explores three SPARQL-based techniques to solve Semantic Web tasks that often require similarity measures, such as semantic data integration, ontology mapping, and Semantic Web service matchmaking. Our aim is to see how far it is possible to integrate customized similarity functions (CSF) into SPARQL to achieve good results for these tasks. Our first approach exploits virtual triples calling property functions to establish virtual relations among resources under comparison; the second approach uses extension functions to filter out resources that do not meet the requested similarity criteria; finally, our third technique applies new solution modifiers to post-process a SPARQL solution sequence. The semantics of the three approaches are formally elaborated and discussed. We close the paper with a demonstration of the usefulness of our iSPARQL framework in the context of a data integration and an ontology mapping experiment.http://www.bibsonomy.org/bibtex/247494770bd04e745700dd2998fc668bb/iswc2007iswc20072007-11-07T19:13:58+01:002007 application_software data_management database datum graph grid_computing information_integration iswc peer-to-peer repository research_09 semantic_web software_agent structured web web_service <span class="authorEditorList"><a href="/author/Harth">Andreas Harth</a>, <a href="/author/Umbrich">Jürgen Umbrich</a>, <a href="/author/Hogan">Aidan Hogan</a>, and <a href="/author/Decker">Stefan Decker</a> </span><em>Proceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference ISWC/ASWC2007, Busan, South Korea, </em><em>volume 4825 of LNCS, </em><em>page 211--224. </em><em>Berlin, Heidelberg, </em><em>Springer Verlag, </em>(<em>November 2007</em>)Wed Nov 07 19:13:58 CET 2007Berlin, HeidelbergProceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference (ISWC/ASWC2007), Busan, South Koreahttp://data.semanticweb.org/conference/iswc-aswc/2007/proceedingsNovember211--224LNCSYARS2: A Federated Repository for Querying Graph Structured Data from the Web482520072007 application_software data_management database datum graph grid_computing information_integration iswc peer-to-peer repository research_09 semantic_web software_agent structured web web_service We present the architecture of an end-to-end semantic search engine that uses a graph data model to enable interactive query answering over structured and interlinked data collected from many disparate sources on the Web.

One of their main advantages is that natural language labels, used to describe their contents, are easily understood by human users. However, at the same time, this is also one of their main disadvantages as these same labels are ambiguous and very hard to be reasoned about by software agents. This fact creates an insuperable hindrance for classifications to being embedded in the Semantic Web infrastructure. This paper presents an approach to converting classifications into lightweight ontologies, and it makes the following contributions: (i) it identifies the main NLP problems related to the conversion process and shows how they are different from the classical problems of NLP; (ii) it proposes heuristic solutions to these problems, which are especially effective in this domain; and (iii) it evaluates the proposed solutions by testing them on DMoz data.http://www.bibsonomy.org/bibtex/25af80e2b00a6eddb399e4c921f408e91/iswc2007iswc20072007-11-07T19:13:58+01:002007 claim iswc research_04 weaving web <span class="authorEditorList"><a href="/author/Groza">Tudor Groza</a>, <a href="/author/Möller">Knud Möller</a>, <a href="/author/Handschuh">Siegfried Handschuh</a>, <a href="/author/Trif">Diana Trif</a>, and <a href="/author/Decker">Stefan Decker</a> </span><em>Proceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference ISWC/ASWC2007, Busan, South Korea, </em><em>volume 4825 of LNCS, </em><em>page 197--210. </em><em>Berlin, Heidelberg, </em><em>Springer Verlag, </em>(<em>November 2007</em>)Wed Nov 07 19:13:58 CET 2007Berlin, HeidelbergProceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference (ISWC/ASWC2007), Busan, South Koreahttp://data.semanticweb.org/conference/iswc-aswc/2007/proceedingsNovember197--210LNCSSALT: Weaving the claim web482520072007 claim iswc research_04 weaving web In this paper we present a solution for "weaving the claim web", i.e. the creation of knowledge networks via so-called claims stated in scientific publications created with the SALT (Semantically Annotated LaTeX) framework.

Automatic ontology instantiation from Web sources is one of the possible solutions to this problem and aims at the computer supported population of an ontology through the exploitation of (redundant) information available on the Web. In this paper we present AllRight, a comprehensive ontology instantiating system. In particular, the techniques implemented in AllRight are designed for application scenarios, in which the desired instance information is given in the form of tables and for which existing Information Extraction approaches based on statistical or natural language processing methods are not directly applicable. Within AllRight, we have therefore developed new techniques for dealing with tabular instance data and combined these techniques with existing methods. The system supports all necessary steps for ontology instantiation, i.e. web crawling, name extraction, document clustering as well as fact extraction and validation. AllRight has been successfully evaluated in the popular domains of digital cameras and notebooks leading to a about eighty percent accuracy of the extracted facts given only a very limited amount of seed knowledge.http://www.bibsonomy.org/bibtex/20a0d460b8f613cff96c984ad194bf3d5/iswc2007iswc20072007-11-07T19:13:58+01:002007 application_software biology iswc leveraging life owl research_14 science semantic semantic_web technology web <span class="authorEditorList"><a href="/author/Golbreich">Christine Golbreich</a>, <a href="/author/Horridge">Matthew Horridge</a>, <a href="/author/Horrocks">Ian Horrocks</a>, <a href="/author/Motik">Boris Motik</a>, and <a href="/author/Shearer">Rob Shearer</a> </span><em>Proceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference ISWC/ASWC2007, Busan, South Korea, </em><em>volume 4825 of LNCS, </em><em>page 169--182. </em><em>Berlin, Heidelberg, </em><em>Springer Verlag, </em>(<em>November 2007</em>)Wed Nov 07 19:13:58 CET 2007Berlin, HeidelbergProceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference (ISWC/ASWC2007), Busan, South Koreahttp://data.semanticweb.org/conference/iswc-aswc/2007/proceedingsNovember169--182LNCSOBO and OWL: Leveraging Semantic Web Technologies for the Life Sciences482520072007 application_software biology iswc leveraging life owl research_14 science semantic semantic_web technology web OBO is an ontology language that has often been used for modeling ontologies in the life sciences. Its definition is relatively informal, so, in this paper, we provide a clear specification for OBO syntax and semantics via a mapping to OWL. This mapping also allows us to apply existing Semantic Web tools and techniques to OBO. We show that Semantic Web reasoners can be used to efficiently reason with OBO ontologies. Furthermore, we show that grounding the OBO language in formal semantics is useful for the ontology development process: using an OWL reasoner, we detected a likely modeling error in one OBO ontology.http://www.bibsonomy.org/bibtex/252943a6298169f5a552bffbbee352937/iswc2007iswc20072007-11-07T19:13:58+01:002007 bookmarking iswc personalization research_06 search social tagging web <span class="authorEditorList"><a href="/author/Noll">Michael Noll</a>, and <a href="/author/Meinel">Christoph Meinel</a> </span><em>Proceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference ISWC/ASWC2007, Busan, South Korea, </em><em>volume 4825 of LNCS, </em><em>page 365--378. </em><em>Berlin, Heidelberg, </em><em>Springer Verlag, </em>(<em>November 2007</em>)Wed Nov 07 19:13:58 CET 2007Berlin, HeidelbergProceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference (ISWC/ASWC2007), Busan, South Koreahttp://data.semanticweb.org/conference/iswc-aswc/2007/proceedingsNovember365--378LNCSWeb search personalization via social bookmarking and tagging482520072007 bookmarking iswc personalization research_06 search social tagging web In this paper, we present a new approach to web search personalization based on user collaboration and sharing of information about web documents.

We show how to design and implement such a system in practice and investigate its feasibility and usefulness with large sets of real-word data and a user study.http://www.bibsonomy.org/bibtex/2f51ec751599c6ed13c1d6766313c8b2f/iswc2007iswc20072007-11-07T19:13:58+01:002007 application_software datum in_use_1 iswc nucleus ontology_(computer_science) open semantic_web software_framework tool web <span class="authorEditorList"><a href="/author/Auer">Sören Auer</a>, <a href="/author/Bizer">Chris Bizer</a>, <a href="/author/Lehmann">Jens Lehmann</a>, <a href="/author/Kobilarov">Georgi Kobilarov</a>, <a href="/author/Cyganiak">Richard Cyganiak</a>, and <a href="/author/Ives">Zachary Ives</a> </span><em>Proceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference ISWC/ASWC2007, Busan, South Korea, </em><em>volume 4825 of LNCS, </em><em>page 715--728. </em><em>Berlin, Heidelberg, </em><em>Springer Verlag, </em>(<em>November 2007</em>)Wed Nov 07 19:13:58 CET 2007Berlin, HeidelbergProceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference (ISWC/ASWC2007), Busan, South Koreahttp://data.semanticweb.org/conference/iswc-aswc/2007/proceedingsNovember715--728LNCSDBpedia: A Nucleus for a Web of Open Data482520072007 application_software datum in_use_1 iswc nucleus ontology_(computer_science) open semantic_web software_framework tool web DBpedia is a community effort to extract structured information from Wikipedia and to make this information available on the Web. DBpedia allows you to ask sophisticated queries against datasets derived from Wikipedia and to link other datasets on the Web to Wikipedia data. We describe the extraction of the DBpedia datasets, and how the resulting information can be made available on the Web for humans and machines. We describe some emerging applications from the DBpedia community and show how website operators can reduce costs by facilitating royalty-free DBpedia content within their sites. Finally, we present the current status of interlinking DBpedia with other open datasets on the Web and outline how DBpedia could serve as a nucleus for an emerging Web of open data sources.http://www.bibsonomy.org/bibtex/2a6a1c52209604c7c840ad55e2976da2e/iswc2007iswc20072007-11-07T19:13:58+01:002007 application_software designing information_extraction iswc multimedia ontology research_11 semantic_web web web_annotation <span class="authorEditorList"><a href="/author/Arndt">Richard Arndt</a>, <a href="/author/Troncy">Raphael Troncy</a>, <a href="/author/Staab">Steffen Staab</a>, <a href="/author/Hardman">Lynda Hardman</a>, and <a href="/author/Vacura">Miroslav Vacura</a> </span><em>Proceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference ISWC/ASWC2007, Busan, South Korea, </em><em>volume 4825 of LNCS, </em><em>page 29--42. </em><em>Berlin, Heidelberg, </em><em>Springer Verlag, </em>(<em>November 2007</em>)Wed Nov 07 19:13:58 CET 2007Berlin, HeidelbergProceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference (ISWC/ASWC2007), Busan, South Koreahttp://data.semanticweb.org/conference/iswc-aswc/2007/proceedingsNovember29--42LNCSCOMM: Designing a Well-Founded Multimedia Ontology for the Web482520072007 application_software designing information_extraction iswc multimedia ontology research_11 semantic_web web web_annotation Semantic descriptions of non-textual media available on the web can be used to facilitate retrieval and presentation of media assets and documents containing them. While technologies for multimedia semantic descriptions already exist, there is as yet no formal description of a high quality multimedia ontology that is compatible with existing (semantic) web technologies. We explain the complexity of the problem using an annotation scenario. We then derive a number of requirements for specifying a formal multimedia ontology before we present the developed ontology, COMM, and evaluate it with respect to our requirements. We provide an API for generating multimedia annotations that conform to COMM.http://www.bibsonomy.org/bibtex/2cdacd0aafb1b584dac65647ccb3844bf/iswc2007iswc20072007-11-07T19:13:58+01:002007 doctoral_consortium information integration iswc probabilistic retrieval semantic web <span class="authorEditorList"><a href="/author/Predoiu">Livia Predoiu</a> </span><em>Proceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference ISWC/ASWC2007, Busan, South Korea, </em><em>volume 4825 of LNCS, </em><em>page 930--934. </em><em>Berlin, Heidelberg, </em><em>Springer Verlag, </em>(<em>November 2007</em>)Wed Nov 07 19:13:58 CET 2007Berlin, HeidelbergProceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference (ISWC/ASWC2007), Busan, South Koreahttp://data.semanticweb.org/conference/iswc-aswc/2007/proceedingsNovember930--934LNCSProbabilistic Information Integration and Retrieval in the Semantic Web482520072007 doctoral_consortium information integration iswc probabilistic retrieval semantic web This paper proposes research on a probabilistic framework for information integration and retrieval in the Semantic Web.

SAWSDL provides a standard means by which WSDL documents can be related to semantic descriptions, such as those provided by OWL-S (OWL for Services) and other Semantic Web services frameworks. We argue that the value of SAWSDL cannot be realized until its use is specified, and its benefits explained, in connection with a particular framework. This paper is an important first step toward meeting that need, with respect to OWL-S. We explain what OWL-S constructs are appropriate for use with the various SAWSDL annotations, and provide a rationale and guidelines for their use. In addition, we discuss some weaknesses of SAWSDL, and identify some ways in which OWL-S could evolve so as to integrate more smoothly with SAWSDL.http://www.bibsonomy.org/bibtex/23a49ae2ff83b89c5e7b0ac07675d96cf/iswc2007iswc20072007-11-07T19:13:58+01:002007 application_software dog food in_use_1 iswc metadata ontology_(computer_science) project recipe semantic semantic_web web <span class="authorEditorList"><a href="/author/Möller">Knud Möller</a>, <a href="/author/Heath">Tom Heath</a>, <a href="/author/Handschuh">Siegfried Handschuh</a>, and <a href="/author/Domingue">John Domingue</a> </span><em>Proceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference ISWC/ASWC2007, Busan, South Korea, </em><em>volume 4825 of LNCS, </em><em>page 795--808. </em><em>Berlin, Heidelberg, </em><em>Springer Verlag, </em>(<em>November 2007</em>)Wed Nov 07 19:13:58 CET 2007Berlin, HeidelbergProceedings of the 6th International Semantic Web Conference and 2nd Asian Semantic Web Conference (ISWC/ASWC2007), Busan, South Koreahttp://data.semanticweb.org/conference/iswc-aswc/2007/proceedingsNovember795--808LNCSRecipes for Semantic Web Dog Food - The ESWC and ISWC Metadata Projects482520072007 application_software dog food in_use_1 iswc metadata ontology_(computer_science) project recipe semantic semantic_web web Semantic Web conferences such as ESWC and ISWC offer prime opportunities to test and showcase semantic technologies. Conference metadata about people, papers and talks is diverse in nature and neither too small to be uninteresting or too big to be unmanageable. Many metadata-related challenges that may arise in the Semantic Web at large are also present here. Metadata must be generated from sources which are often unstructured and hard to process, and may originate from many different players, therefore suitable workflows must be established. Moreover, the generated metadata must use appropriate formats and vocabularies, and be served in a way that is consistent with the principles of linked data. This paper reports on the metadata efforts from ESWC and ISWC, identifies specific issues and barriers encountered during the projects, and discusses how these were approached. Recommendations are made as to how these may be addressed in the future, and we discuss how these solutions may generalize to metadata production for the Semantic Web at large.
