Digital Index of North American Archaeology, Linking Sites and Literature

Finds Smithsonian trinomials and other site identifiers from published literature to link to sites in DINAA

Project Abstract

The Digital Index of North American Archaeology, Linking Sites and Literature (DINAA LSL) provides a uniquely nuanced way to begin library research in American archaeology. Published literature which contains archaeological site numbers is provided in the DINAA LSL with full bibliographic citations and stable URLs (as available) which can be associated with geographic regions, and archaeological concepts of culture, time, and investigation represented in the DINAA archaeological site dataset.

Links with American Antiquity Articles

The DINAA LSL may be used to begin a query for literature about the archaeological record using spatial, temporal, or cultural concepts, and then branch into literature about archaeological sites as appropriate. The 2016-2017 segment of DINAA LSL development involved visual identification of archaeological site numbers within articles from the most recent non-embargoed decade of the journal American Antiquity in JSTOR (2004-2013). This work was led by Joshua Wells and conducted at Indiana University South Bend through the support of the Institute of Museum and Library Services. The effort included identification of site number elements in article text, tables, and figures (which may not be subject to query via optical character recognition). When possible, these site numbers were associated with their US state and county locations, most commonly with site numbers in the Smithsonian trinomial format (SSCCNN) where "SS" is a 1-2 digit number designating the state of origin, "CC" is a two letter abbreviation associated with the county name (or in some cases, a National Park), and "NN" is a unique number attributed to the site (usually its place in an ordinal arrangement of recording from first to last); other site number systems that include designators such as National Parks or National Forests have been accommodated to approximate their position on a political US county map. Bibliographic information and stable URLs to items of published literature about archaeological sites in DINAA have been linked with the full representation of those sites in DINAA.

Links with the Index of Texas Archaeology

In November through December 2017, the DINAA team extracted trinomial identifiers and associations with reports through automated requests that obtained public metadata from the Index of Texas Archaeology (ITA). The system hosting the ITA provided an Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) web service that returned Dublin Core metadata records. Eric Kansa with the DINAA team developed and ran a software process software process to request metadata records from the ITA's OAI-PMH service. The software attempted to identify and extract Smithsonian Trinomials in the Dublin Core title, abstract, and subject elements returned from the OAI-PMH service. The software only looked for trinomials returned in the OAI-PMH provided metadata, not the full text of the associated reports published by the ITA. The software then associated these site identifiers within appropriate counties for state of Texas. Taylor Wiley, a student member of the DINAA team, checked the software identified trinomials and identified and corrected a few errors, as indicated in notes associated with certain site records.

Future Work

Expansion of the DINAA LSL in late 2017 and beyond will use a combination of automated and human text mining in repositories and the open Web. DINAA LSL obviously does not represent the entire body of published literature in American archaeology, but it does provide a starting point and a new way of interacting with publications for professional researchers, educators and students, and the general public.

Editorial Note

Open Context editors work with data contributors to annotate datasets to shared vocabularies, ontologies, and other standards using 'Linked Open Data' (LOD) methods.

The annotations presented above approximate some of the meaning in this contributed data record to concepts defined in shared standards. These annotations are provided to help make datasets easier to understand and use with other datasets.
