Enum Task 

#[non_exhaustive]
pub enum Task {
    NER,
    IntraDocCoref,
    InterDocCoref,

}

The primary NLP task a dataset is designed for.

A dataset may support multiple tasks (e.g., NER + Entity Linking), but has one primary task that determines its structure.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NER

Named Entity Recognition (sequence labeling)

IntraDocCoref

Intra-document coreference resolution

InterDocCoref

Inter-document (cross-document) coreference resolution

NED

Named Entity Disambiguation / Entity Linking to KB

RelationExtraction

Relation Extraction between entities

EventExtraction

Event extraction and argument role labeling

DiscontinuousNER

Discontinuous/nested NER (e.g., CADEC, ShARe)

VisualNER

Visual document NER (forms, receipts, etc.)

TemporalNER

Temporal NER (diachronic entities, time expressions)

AspectExtraction

Sentiment/opinion target extraction

SlotFilling

Slot filling for dialogue systems

POS

Part-of-speech tagging (often bundled with NER)

DependencyParsing

Dependency parsing

Implementations

impl Task

pub const fn produces_entities(&self) -> bool

Returns true if this task produces entity spans.

pub const fn involves_coreference(&self) -> bool

Returns true if this task involves coreference chains.

pub const fn involves_kb_linking(&self) -> bool

Returns true if this task links to external knowledge bases.

pub const fn involves_relations(&self) -> bool

Returns true if this task extracts relations between entities.

impl Task

pub const ALL: &'static [Task]

All task variants for iteration.

pub const fn code(&self) -> &'static str

Short code for this task (lowercase, no spaces).

Trait Implementations

impl Clone for Task

fn clone(&self) -> Task

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Task

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Task

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Task

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for Task

fn from_str(s: &str) -> Result<Self, Self::Err>

Parse task from string (case-insensitive, supports common aliases).

Examples

use anno_core::core::dataset::Task;

assert_eq!("ner".parse::<Task>().unwrap(), Task::NER);
assert_eq!("coref".parse::<Task>().unwrap(), Task::IntraDocCoref);
assert_eq!("entity_linking".parse::<Task>().unwrap(), Task::NED);
assert_eq!("RE".parse::<Task>().unwrap(), Task::RelationExtraction);

type Err = String

The associated error which can be returned from parsing.

impl Hash for Task

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Task

fn eq(&self, other: &Task) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Task

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Task

impl Eq for Task

impl StructuralPartialEq for Task
