Results of semantic queries for "carbon cycling" for datasets in the DataONE catalog

Abstract:

DataONE (https://www.dataone.org) is a federation of institutions involved with the earth and environmental sciences that share data through common cyberinfrastructure. In 2016, the DataONE project carried out a quantification of the utility of semantic query, by measuring the precision and recall of relevant datasets available through that catalog. Precision is defined as the proportion of relevant data in the retrieved results, and recall is the proportion of relevant data retrieved, compared to all relevant data present in the repository (see Methods).

This dataset contains the queries and results of that study. Four data tables are included. First, a table of the 10 queries, which were formatted in several ways, including natural language and text strings (for plain text searches of various parts of metadata), and URIs for measurements in the EcoSystem Ontology (ECSO). A second table contains 994 relevant datasets in the DataONE catalog, with a column for each of the ten queries and boolean value indicating whether the dataset is a match for that query. Two query results tables are included, for the raw and summarized results of the query tests. A fifth entity contains the zipped code (R language) used to perform the queries in the DataONE system.

When run against approximately 1000 datasets (in October, 2016), results for the ten queries ranged from 0-50% (precision) and 0-100% (recall), indicating that traditional searches may sometimes be adequate to return all relevant data in a corpus, but results can be erratic and inconsistent, with potentially large returns of irrelevant data in the result set.

Methods and protocols used in the collection of this data package

Description:

A field of study, “carbon cycling”, was identified as important to researchers, and particularly to synthesis scientists. A set of natural language queries related to carbon cycling were drafted based on interactions with NCEAS’s researchers.

Description:

A corpus of 925 datasets was identified in the DataONE catalog that had sufficient metadata for detailed queries and annotation (measurement-level). All datasets in the corpus had metadata in Ecological Metadata Language (EML), because DataONE contributors who use EML all require measurement-level metadata.

Description:

The corpus was reviewed, and datasets relevant to carbon cycling were annotated with classes from the ECSO ontology using 3 mechanisms:

a. Manual annotation (a knowledgeable curator assigned classes to specific columns of data.

b. Bioportal annotation algorithm

c. Two annotation algorithms using the Earth Science Ontology Repository (ESOR) annotation algorithms. RPI's annotation web service indexes a fixed set of ontologies but uses the context and entropy scoring of classes to determine the best-scoring annotation results (original and cosine method)

Annotated datasets were cached in a DataONE coordinating node (test node), and the annotations added to the SOLR index with explicit keys.

Description:

SOLR searches were performed against the test node and “hits” tabulated. Precision and recall were summarized.

a. Definition of Recall: A/(A+B), where A = # of relevant retrieved and B = # of relevant records NOT retrieved

b. Definition of Precision: A/(A+C), where A = # of relevant retrieved and C = # of irrelevant records retrieved

Description:

Results were tabulated for 7 types of searches:

1. Full_text: Anywhere in the metadata (EML) record

2. Metacat_ui: Fields found in the Metacat User Interface

3. Metacat_filtered: Dataset column-metadata will be searched

4. Manual_annot: Annotations added manually

5. Automated annotation - Bioportal_annot

6. Automated annotation - ESOR_annot

7. Automated annotation- ESOR-cosine

Abstract:

Searching in DataONE currently focuses on fielded and full-text metadata. It does not allow precise queries of measurement types primarily because the metadata corpus contains uncontrolled descriptions of measurements (e.g., variable names, descriptions, units, etc.), making it impossible to find all datasets that use a particular measurement type. DataONE plans to extend its search system using scalable semantic annotation and inferencing. Key activities include: (a) Defining the scope of prototypes and the production framework; (b) Selecting contributing ontologies and terminologies (e.g., CF, CUAHSI, ENVO, SWEET) and extending these as needed to provide coverage of measurement types; (c) Defining the annotation representation framework, e.g., by extending PROV-O or AO to enable measurement type association with attributes of entities within a data package; (d) Implementing annotation storage framework and user interfaces to facilitate ease of manual annotation by DataONE users through investigator tools; (e) Developing data mining algorithms to infer from data and metadata the measurement types aligned with the ontology, and incorporating automated annotation capabilities into Investigator Tools; and (f) Developing extensions to the DataONE content indexing, programmatic query services, and user interfaces to enable discovery through controlled definitions of measurement types.
