Metadata++: Terms & Relationships

same term may appear in more than one vocabulary – with

different, even contradictory broader-term/narrower-term

relationships


Metadata++: Terms & Relationships

synonym relationships


Metadata++: Associative Relationships

functional relationships such aswildlife-habitat relationships -

supports similarity search & browsing!


Metadata++

• Exploiting broader-term-narrower-term– If you attach a narrow term…attach all broader

terms as well– If you search for a term…search for all narrow

terms as well

• Support multiple hierarchies - with cross-references indicated as synonyms (as available)

Metadata++

• Inspired by Dublin Core, Z39.19 (Thesaurus), …• Simple, uniform model: terms & relationships• No classes• No attributes (for terms or objects)• Basic idea – broader-term/narrower-term relationship

is intentionally overloaded to represent– Broader-term/narrower-term– Type – instance – Collection (set) – member– Traditional property name

• Model has been formalized; query and browse capability is being defined


MetaData eXtract

• Metadata attachment may take some time

• MDX helps by suggesting terms from Metadata ++

• Results are suggested to the user … interactively

The district silviculturalist at the McKenzie Ranger District on the Willamette National Forest is working on an EIS for a timber sale located within the upper McKenzie watershed. During the scoping process, the silviculturalist and rest of the IDT identified two areas in particular where the objectives would be to promote and accelerate the development of late successional characteristics over time.

Both areas are located within Douglas-fir forest types; one within a Western hemlock/dwarf Oregon grape plant association, or potential vegetation type, and one in a riparian reserve that has a plant association of Western hemlock/Oregon oxalis......

Querying a Superimposed Schematic

Issue [AppealDecision(id="1570-1-0032-10").concern(order=1)] The decision violates the Federal Advisory Committee Act (FACA). The illegal advisory committee played a central role in influencing the Forest Service Decision.

Issue [AppealDecision(id="1570-1-0032-10").concern(order=2)] The decision significantly reduces hunting opportunity and habitat for deer and elk.

Issue [AppealDecision(id="1570-1-0035-13").concern(order=1)] The District Ranger's decision is not in accordance with the legal requirements of the National Environmental Policy Act, the National Forest Management Act, and the Forest and Rangeland Renewable Resources Planning Act.

Issue [AppealDecision(id="1570-1-0038-19").concern(order=1)] Current stand condition is not adequately addressed, impacts on soil quality are not addressed, and that impacts to various species are not considered, including several late successional species, survey and manage species, and management indicator species.

concerning the Mount Hood National Forest”

Superimposed Schematics

• Entity-relationship-style model is superimposed over arbitrary, base documents

• Each entity, each attribute, and each relationship can be “anchored” at some text excerpt

• Includes “authoritative” entities – such as for persontitle

Superimposed Schematics

• Represented using the uni-level description– Generic, uniform representation for structured information– Can accommodate a variety of data models (database

models, XML, RDF, topic maps, …)– Can accommodate schema-first, schema-later, schema-

optional information– Can accommodate multiple levels of schema-instance

relationships in a single model– Based on a metamodel (with basic structures such as set,

bag, list, struct, attribute, and scalar)

• Logic-based language (Datalog) can easily be used to transform data (model-model, schema-schema, …)


What is Superimposed Information?

data “placed over” existing information sources to

highlight annotate elaborate select collect organize connect reuse

information elements

often to support new applications, beyond the original


Examples of Superimposed Information

Non-electronic examples:

Commentaries on religious texts, law, literature Concordances, citation indexes

Electronic examples:

Bookmark file in your web browser RDF metadata
