Semantic annotation of natural history collections

Abstract

Large collections of historical biodiversity expeditions are housed in natural history museums throughout the world. Potentially they can serve as rich sources of data for cultural historical and biodiversity research. However, they exist as only partially catalogued specimen repositories and images of unstructured, non-standardised, handwritten text and drawings. Although many archival collections have been digitised, disclosing their content is challenging. They refer to historical place names and outdated taxonomic classifications and are written in multiple languages. Efforts to transcribe the handwritten text can make the content accessible, but semantically describing and interlinking the content would further facilitate research. We propose a semantic model that serves to structure the named entities in natural history archival collections. In addition, we present an approach for the semantic annotation of these collections whilst documenting their provenance. This approach serves as an initial step for an adaptive learning approach for semi-automated extraction of named entities from natural history archival collections. The applicability of the semantic model and the annotation approach is demonstrated using image scans from a collection of 8,000 field book pages gathered by the Committee for Natural History of the Netherlands Indies between 1820 and 1850, and evaluated together with domain experts from the field of natural and cultural history.

Automatic Semantic Description Extraction from Social Big Data for Emergency Management

“…This is a significant problem in SBD, which primarily represents implied content. Also, some implicit information needs background knowledge to support its inference, which can be addressed by combining the semantic-based bridge with ontology models (Stepanov et al 2018, Stork et al 2018. This can describe both directly and indirectly related entities by identifying hidden relations.…”

The Importance and Potential Value of a Regional Midsize Arthropod Collection: An Example of IBULC

“…Fisher and Mantle (2012) described noninvasive specimen scanning methodology, without even taking items out of collection drawers. Stork et al (2019) have recently started a global-scale project to link digital data of specimen collections of natural history findings worldwide in a single Internet database. Digitized information of collections makes them more accessible to a wider scientific community and suitable for digital analysis for a broad range of future research (Colvin 2014;Enghoff and Seberg 2006;Gutiérrez and Pine 2017;McLean et al 2015;NSCA 2005;Ownes and Duin 2008;Page et al 2015;Sánchez-Cordero and Martinez-Meyer 2000;Singh and Singh 2012;Wiedenmann, Dowling, and Barnes 2014).…”

Media Forensics Challenge image provenance evaluation and state-of-the-art analysis on large-scale benchmark datasets

“…Provenance analysis is a well-known topic in data-centric domains such as the data annotation, management, and warehousing [18][19][20][21]. However, the problem of IPA is not intensively studied so far in the literature.…”
