FrameNet

FrameNet

FrameNet is a project housed at the International Computer Science Institute in Berkeley, California which produces an electronic resource based on
semantic frames. A semantic frame can be thought of as a concept with a script. It is used to describe an object, state or event. The FrameNet lexical database contains around 10,000 "lexical units" (a pairing of a word with a meaning; polysemous words are represented by several "lexical units"), 800 semantic "frames" and over 120,000 example sentences. FrameNet is largely the creation of Charles J. "Chuck" Fillmore.

Concepts

Frames

Examples of "frame" names are Being_born and Locative_relation. Alongside the name, a "frame" contains a textual description of the concept it represents.

Frame elements

Each "frame" has a number of core and non-core "frame elements" which can be thought of as semantic roles. The only core "frame element" of the "Being_born" frame is called Child, non-core "frame elements" being Time, Place, Relatives, etc.

Lexical Units

Alongside the "frame", each "lexical unit" is associated with a number of "frame elements" through "annotations".

Realizations

FrameNet has shallow data on syntactic roles that "frame elements" play in the example sentences. For the example sentence above, the "frame element"s Child and about AD 460 are both "noun phrase"s.

Valences

FrameNet also exposes the statistics on the "valences" of the "frames", that is the number and the position of the "frame elements" within example sentences. The sentence She was BORN about AD 460 falls in the valence pattern NP Ext, INI --, NP Dep which occurs two times in the example sentences.

Example sentences

"Frames" are associated with example sentences and "frame elements" are marked within the sentences. Thus the sentence She was BORN about AD 460 is associated with the frame Being_born, while She is marked as the "frame element" Child and about AD 460 is marked as Time.(See the [http://framenet.icsi.berkeley.edu/fnReports/displayReport.php?anno=9791 FrameNet Annotation Report] for born.v.)
