Workshop on Social Media and the Web of Linked Data at EUROLAN 2015 - - PowerPoint PPT Presentation

Workshop on Social Media and the Web of Linked Data at EUROLAN 2015 Summer School on Linguistic Linked Open Data 18 July 2015 | Sibiu, Romania

This work continues the research began in 2013, having the main scope of building a corpus

• f

annotated entities and semantic

• relations. The used text is the Romanian version
• f the novel

novel novel novel “Quo Quo Quo Quo Vadis Vadis Vadis Vadis”, authored by the Nobel laureate Henryk Henryk Henryk Henryk Sienkiewicz Sienkiewicz Sienkiewicz Sienkiewicz. The corpus is manually annotated with 12 types

• f anaphoric relations (e.g. coref, member-of,

part-of, has-as-part) and almost 30 types of non-anaphoric relations (e.g. parent-of, child-

• f, love, friendship, hate, superior-of, inferior-
• f, colleague-of ).

Entities are realized in texts as noun noun noun noun phrases phrases phrases phrases (NP NP NP NP) whose heads are nouns or pronouns.

Entities in QuoVadis corpus represent descriptions of persons, gods and any grouping of them.

Anaphoric (noted REFERENTIAL) relations:

coreferential, isa, class-of, member-of, has-as-member, part-of, has-as-part, etc.

Affectional (noted AFFECT) relations: friend-of,

fear-of, love, loved-by, hate, hated-by, worship, worshiped-by, etc.

Kinship (noted KINSHIP) relations: parent-of,

child-of, sibling-of, spouse-of, unknown, etc.

Social (noted SOCIAL) relations: superior-of,

inferior-of, colleague-of, in- competition-with, etc.

Properties: Properties: Properties: Properties:

• Imbricated entities have always separate heads.
• There are not entities that intersect and which are non-imbricated.
• The direction of the relation is from the larger entity (FROM entity)

to the nested entity (TO entity)

Manual annotations include:

the relation’s span the relation type the two entities the trigger

iubită este Ligia de familia lui Plautius dear Ligia was to Plautius

relation’s span

< < < < < < < < > > > > > > > > 1:[ 1:[ 1:[ 1:[ 1:[ 1:[ 1:[ 1:[ ] ] ] ] ] ] ] ] 2:[ 2:[ 2:[ 2:[ 2:[ 2:[ 2:[ 2:[ ] ] ] ] ] ] ] ]

Our study:

addresses only to

imbricated entities

uses lexical and

syntactical patterns

no lexical information is considered here the main scope is to generalize the syntactic

patterns found in the training corpus under the same relation realization

applied on the following relations:

• REFERENTIAL.has-as-member
• REFERENTIAL.has-as-part
• REFERENTIAL.has-as-subgroup
