Multilingual Datasets for Word Sense Disambiguation

In this repository we release an updated version of SemEval-2013 task 12 and SemEval-2015 task 13 multilingual gold standards. The original data used old versions of BabelNet, i.e., 1.1.1 and 2.5, respectively, which are no longer available. To ease their use and allow a fair comparison among systems, we mapped all the possible gold keys in the original datasets to the latest available version of BabelNet (indices version 4.0 and API version 4.0.1), normalized the Part-of-Speech tags to the Universal POS tags and handled the multiword instances so that they are now associated with a single id and contained within a single XML tag. Furthermore, we provide two standard splits:

1. all: comprising all the instances that we managed to map,
2. wn: comprising only the instances tagged with a BabelNet synset which contains a sense in WordNet. This second split is a subset of all.

Datasets and Inventories Creation

To create the new datasets, whenever possible, we used the WordNet sense keys provided with the original data. Thanks to WordNet keys (version 3.0) we could easily map the old BabelNet synset id with the new synset id associated to that sense key in BabelNet 4.0. As for those instances that were not associated with a WordNet sense key, instead, we used the original BabelNet indices to retrieve the Wikipedia page title and the gloss associated with the target BabelNet synset (both in English and in the specific language) and searched them in the new indices. Whenever a match was found (prioritising titles over glosses and English over language-specific information ) we mapped the instance to the found BabelNet id. If no match was found we discarded the instance.

Build the Inventory

To correctly build the inventory, i.e., the association between a lexeme (lemma#pos) and its possible meanings, you shall follow this procedure.

• Login or sign up to babelnet.org
• Request and download BabelNet indices.
• Download BabelNet API.
• cd inventory_building
• cp /path/to/BabelNet-API-[VERSION]/resources/* .
• cp /path/to/BabelNet-API-[VERSION]/config .
• Setup the properties files properly this step is essential, if not properly setup, you may end up having wrong inventories (More on this will follow).
• bash create_inventories_sem13_15.sh -i /path/to/output_inventories/ -d /path/to/multilingual_datasets -s [wn|all]
• Check out the inventories in /path/to/output_inventories/[lang] where lang may be one among [de, es, fr, it]

The multilingual_datasets can be extracted by running tar xvzf multilingual_wsd_*_v1.0.tar.gz

Example:

$ pwd
> /home/user/downloads/
$ cd inventory_building
$ cp -r /home/user/data/BabelNet-API-4.0.1/resources . 
$ cp -r /home/user/data/BabelNet-API-4.0.1/config . 
$ # setting up paths in configs
$ bash create_inventories_sem13_15.sh -i /home/user/downloads/inventory_building/data/multilingual_wsd_wn_v1.0/inventories/ -d /home/user/downloads/inventory_building/data/multilingual_wsd_wn_v1.0/ -s wn
$ ls /home/user/downloads/inventory_building/data/multilingual_wsd_wn_v1.0/inventories/
> de/ es/ fr/ it/
$ ls /home/user/downloads/inventory_building/data/multilingual_wsd_wn_v1.0/inventories/it
> inventory.it.withgold.sorted.txt  inventory.it.withgold.txt

Config Setup

In order to properly setup BabelNet config cd into config parent folder and verify that each path in babelnet.properties, babelnet.var.properties, jlt.properties and jlt.var.properties is reachable, as it is written in the files, from the directory you are in.

For example, if I am in /home/user/multilingual_wsd_wn_v1.0 which has config/ as subfolder. I need to be sure that any path written in the aforementioned files is reachable from /home/user/multilingual_wsd_wn_v1.0.

Most importantly, be sure to set:

• babelnet.dir in babelnet.var.properties with the correct path towards BabelNet indices (e.g., BabelNet-4.0.1/ folder).
• jlt.wordnetPrefix and jlt.wordnetVersion in jlt.var.properties file with the path to your WordNet installation and WordNet version (this has to be == 3.0).

BabelNet To WordNet mapping

In case you need to have a mapping between BabelNet offsets and WordNet offsets you can compute it by running

java -jar babelnet_mapping_4.0.jar -build_bn2wn_map /path/to/output/file.txt

This wil generate a tab-separated file having in the first column a BabelNet offset ID and in the subsequent columns the corresponding WordNet (version 3.0) offsets.

Data

Each package is structured as follows:

.
├── semeval2013-{lang}
│   ├── semeval2013-{lang}.data.xml
│   ├── semeval2013-{lang}.gold.key.txt
│   └── semeval2013-{lang}.wnids.gold.key.txt
└── semeval2015-{lang}
    ├── semeval2015-{lang}.data.xml
    ├── semeval2015-{lang}.gold.key.txt
    └── semeval2015-{lang}.wnids.gold.key.txt

Where, lang can be replaced by it|es|fr|de in semeval2013 and inventories folders, and by it|es in the semeval2015 folder.

SemEvals

The semeval folders contains the text to tag in form of xml (.data.xml files) and the gold synsets associated to the instances (.gold.keys.txt files). We note that, not all instances within the XML have a gold synset associated with within the gold.key.txt this is because the same XML can be used for both splits (all and wn) which may have different instances.

Troubleshotting

• If you get the following exception:

2020-07-17 19:27:52,042 [main] [ INFO  ] BabelNet - BabelNet online RESTful API v4.0 written by Francesco Cecconi, Roberto Navigli and Daniele Vannella
Exception in thread "main" java.lang.UnsupportedOperationException: getSynsetIterator: Unsupported online operation

Your babelnet.var.properties in the config/ folder is not properly set and you are attempting to use the online API rather then the indices you should have downloaded.

Solution: edit babelnet.var.properties file and set babelnet.dir to the local path to your BabelNet indeices.
