				SEW: Automatic Construction and Evaluation of a Large Semantically Enriched Wikipedia

					Alessandro Raganato, Claudio Delli Bovi and Roberto Navigli
==============================================================================================================================================

This package contains the two vector representations constructed using SEW, a sense-annotated corpus automatically built from Wikipedia.
The sense inventory of SEW is BabelNet (http://babelnet.org), the largest multilingual encyclopedic dictionary and semantic network.

Two types of vector representation are available:

- WB-SEW: a vector representation for BabelNet synsets in which dimensions are Wikipedia pages;
- SB-SEW: a vector representation for Wikipedia pages in which dimensions are BabelNet synsets.

Both vector representations (WB-SEW and SB-SEW) are available in two different versions:

- One where frequencies are estimated using raw counts (*.rc.tsv);
- One where frequencies are estimated using lexical specificity (*.ls.tsv).

For more information please refer to Section 6.3 (Extrinsic Evaluation: Semantic Similarity) of the reference paper.

Please find below more details on the format:

FORMAT OF THE VECTOR REPRESENTATION FILES
==============================================================================================================================================

Each vector representation file is in tab-separated (.tsv) format, with a single vector in each line.

The format is as follows:

	ENTITY		\t	\t	COMPONENT:VALUE		\t	COMPONENT:VALUE		\t	...	\t	COMPONENT:VALUE

where ENTITY is either the BabelNet synset (WB-SEW) or the Wikipedia page (SB-SEW) being represented by the vector, and the COMPONENT:VALUE
pairs constitute the non-zero dimensions of the vector. Each COMPONENT is either a Wikipedia page (WB-SEW) or a BabelNet synset (SB-SEW).
