The Generation of formal Annotations

The Role of Information Extraction in MUMIS


Information extraction

Information Extraction

  • Information Extraction (IE) is the task of identifying, collecting and normalizing relevant information for a specific application or user.

  • The relevant information is typically represented in form of predefined “templates”, which are filled by means of Natural Language (NL) analysis.


Information extraction 2

Information Extraction (2)

  • IE combines pattern matching mechanism, (shallow) NLP and domain knowledge (terminology and ontology).

  • IE is generally subdivided in following tasks:

    - Named Entity task (NE)

    - Template Element task (TE)

    - Template Relation task (TR)

    - Scenario Template task (ST)

    - Co-reference task (CO)


Subtasks of ie

Subtasks of IE

  • Named Entity task (NE): Mark into the text each string that represents, a person, organization, or location name, or a date or time, or a currency or percentage figure.

  • Template Element task (TE): Extract basic information related to organization, person, and artifact entities, drawing evidence from everywhere in the text.


Subtasks of ie 2

Subtasks of IE (2)

  • Template Relation task (TR): Extract relational information on employee_of, manufacture_of, location_of relations etc. (TR expresses domain-independent relationships).

  • Scenario Template task (ST): Extract pre-specified event information and relate the event information to particular organization, person, or artifact entities (ST identifies domain and task specific entities and relations).

Subtasks of IE (3)

Co-reference task (CO): Capture information on co-refering expressions, i.e. all mentions of a given entity, including those marked in NE and TE
