Semantic Tagging on Historical Maps
Tags assigned by users to shared content can be ambiguous. As a possible
solution, we propose semantic tagging as a collaborative process in which a
user selects and associates Web resources drawn from a knowledge context. We
applied this general technique in the specific context of online historical
maps and allowed users to annotate and tag them. To study the effects of
semantic tagging on tag production, the types and categories of obtained tags,
and user task load, we conducted an in-lab within-subject experiment with 24
participants who annotated and tagged two distinct maps. We found that the
semantic tagging implementation does not affect these parameters, while
providing tagging relationships to well-defined concept definitions. Compared
to label-based tagging, our technique also gathers positive and negative
tagging relationships. We believe that our findings carry implications for
designers who want to adopt semantic tagging in other contexts and systems on
the Web.Comment: 10 page

Event-based Access to Historical Italian War Memoirs
The progressive digitization of historical archives provides new, often
domain specific, textual resources that report on facts and events which have
happened in the past; among these, memoirs are a very common type of primary
source. In this paper, we present an approach for extracting information from
Italian historical war memoirs and turning it into structured knowledge. This
is based on the semantic notions of events, participants and roles. We evaluate
quantitatively each of the key-steps of our approach and provide a graph-based
representation of the extracted knowledge, which allows to move between a Close
and a Distant Reading of the collection.Comment: 23 pages, 6 figure
Analyzing the Tagging Quality of the Spanish OpenStreetMap
In this paper, a framework for the assessment of the quality of OpenStreetMap is presented, comprising a batch of methods to analyze the quality of entity tagging. The approach uses Taginfo as a reference base and analyses quality measures such as completeness, compliance, consistence, granularity, richness and trust . The framework has been used to analyze the quality of OpenStreetMap in Spain, comparing the main cities of Spain. Also a comparison between Spain and some major European cities has been carried out. Additionally, a Web tool has been also developed in order to facilitate the same kind of analysis in any area of the world
Fast, linked, and open – the future of taxonomic publishing for plants: launching the journal PhytoKeys
The paper describes the focus, scope and the rationale of PhytoKeys, a newly established, peer-reviewed, open-access journal in plant systematics. PhytoKeys is launched to respond to four main challenges of our time: (1) Appearance of electronic publications as amendments or even alternatives to paper publications; (2) Open Access (OA) as a new publishing model; (3) Linkage of electronic registers, indices and aggregators that summarize information on biological species through taxonomic names or their persistent identifiers (Globally Unique Identifiers or GUIDs; currently Life Science Identifiers or LSIDs); (4) Web 2.0 technologies that permit the semantic markup of, and semantic enhancements to, published biological texts. The journal will pursue cutting-edge technologies in publication and dissemination of biodiversity information while strictly following the requirements of the current International Code of Botanical Nomenclature (ICBN)
Metadata enrichment for digital heritage: users as co-creators
This paper espouses the concept of metadata enrichment through an expert and user-focused approach to metadata creation and management. To this end, it is argued the Web 2.0 paradigm enables users to be proactive metadata creators. As Shirky (2008, p.47) argues Web 2.0’s social tools enable “action by loosely structured groups, operating without managerial direction and outside the profit motive”. Lagoze (2010, p. 37) advises, “the participatory nature of Web 2.0 should not be dismissed as just a popular phenomenon [or fad]”. Carletti (2016) proposes a participatory digital cultural heritage approach where Web 2.0 approaches such as crowdsourcing can be sued to enrich digital cultural objects. It is argued that “heritage crowdsourcing, community-centred projects or other forms of public participation”. On the other hand, the new collaborative approaches of Web 2.0 neither negate nor replace contemporary standards-based metadata approaches. Hence, this paper proposes a mixed metadata approach where user created metadata augments expert-created metadata and vice versa. The metadata creation process no longer remains to be the sole prerogative of the metadata expert. The Web 2.0 collaborative environment would now allow users to participate in both adding and re-using metadata. The case of expert-created (standards-based, top-down) and user-generated metadata (socially-constructed, bottom-up) approach to metadata are complementary rather than mutually-exclusive. The two approaches are often mistakenly considered as dichotomies, albeit incorrectly (Gruber, 2007; Wright, 2007) .
This paper espouses the importance of enriching digital information objects with descriptions pertaining the about-ness of information objects. Such richness and diversity of description, it is argued, could chiefly be achieved by involving users in the metadata creation process. This paper presents the importance of the paradigm of metadata enriching and metadata filtering for the cultural heritage domain. Metadata enriching states that a priori metadata that is instantiated and granularly structured by metadata experts is continually enriched through socially-constructed (post-hoc) metadata, whereby users are pro-actively engaged in co-creating metadata. The principle also states that metadata that is enriched is also contextually and semantically linked and openly accessible. In addition, metadata filtering states that metadata resulting from implementing the principle of enriching should be displayed for users in line with their needs and convenience. In both enriching and filtering, users should be considered as prosumers, resulting in what is called collective metadata intelligence
Publishing Primary Data on the World Wide Web: Opencontext.org and an Open Future for the Past
More scholars are exploring forms of digital dissemination, including open access (OA) systems where content is made available free of charge. These include peer -reviewed e -journals as well as traditional journals that have an online presence. Besides SHA's Technical Briefs in Historical Archaeology, the American Journal of Archaeology now offers open access to downloadable articles from their printed issues. Similarly, Evolutionary Anthropology offers many full -text articles free for download. More archaeologists are also taking advantage of easy Web publication to post copies of their publications on personal websites. Roughly 15% of all scholars participate in such "self -archiving." To encourage this practice, Science Commons (2006) and the Scholarly Publishing and Academic Resources Coalition (SPARC) recently launched the Scholar Copyright Project, an initiative that will develop standard "Author Addenda" -- a suite of short amendments to attach to copyright agreements from publishers (http://sciencecommons. org/projects/publishing/index.html). These addenda make it easier for paper authors to retain and clarify their rights to self -archive their papers electronically. Several studies now clearly document that self -archiving and OA publication enhances uptake and citation rates (Hajjem et al. 2005). Researchers enhance their reputations and stature by opening up their scholarship.Mounting pressure for greater public access also comes from many research stakeholders. Granting foundations interested in maximizing the return on their investment in basic research are often encouraging and sometimes even requiring some form of OA electronic dissemination. Interest in maximizing public access to publicly financed research is catching on in Congress. A new bipartisan bill, the Federal Research Public Access Act, would require OA for drafts of papers that pass peer review and result from federally funded research (U.S. Congress 2006). The bill would create government -funded digital repositories that would host and maintain these draft papers. University libraries are some of the most vocal advocates for OA research. Current publishing frameworks have seen dramatically escalated costs, sometimes four times higher than the general rate of inflation (Create Change 2003). Increasing costs have forced many libraries to cancel subscriptions and thereby hurt access and scholarship (Association for College and Research Libraries 2003; Suber 2004).This article originally published in Technical Briefs In Historical Archaeology, 2007, 2: -11
