New edition of the shared task: the PARSEME shared task will be reiterated in 2018 - go to edition 1.1.
New! The shared task edition 1.0 corpus annotated with verbal MWEs in 18 languages, has been published at LINDAT/CLARIN.
Basic facts about edition 1.0 (11 April 2017):
- The shared task edition 1.0 is complete.
- 18 languages released their training and test corpora. The overall final corpus of 5.5 million tokens and 60,000 VMWE annotations is distributed under different versions of the Creative Commons license.
- 7 systems participated, 5 of them were multilingual, all 18 languages were covered - see the results.
- The 13th MWE workshop was the culminating event. It featured the shared task presentation paper and 6 system presentation posters (cf. the proceedings).
- We plan editions 1.1 and 2.0 of the shared task in 2018 and 2019, with new languages, enhanced guidelines and corpora, as well as an extended scope.
- Since the PARSEME action is over end of April 2017, these future activities will be coordinated by the SIGLEX-MWE section. New members are welcome to the section.
- In our context, a shared task is usually a competition of existing NLP tools performing a similar task (here: automatic identification of verbal MWEs).
- The organizers of the task provide two corpora:
- A training corpus annotated (possibly manually) according to common guidelines. This corpus is sent to the participants in advance in order to allow them to adapt their systems to the guidelines.
- An evaluation corpus annotated according to the same guidelines. This corpus in its raw (un-annotated) version is used as input to the systems. The participants provide the output produced by their systems on this corpus. This output is compared with the 'gold standard' (the previously annotated version of the same corpus). The results are calculated according to previously agreed on evaluation measures (e.g. precision, recall, F-measure, accuracy, etc.).
- A common final workshop gathering the organizers and the participants allows for comparisons of the (manual and automatic) annotation methodologies, pointing at the challenging issues, etc.
- See the official shared task website for more details on the competition
Objectives of the PARSEME shared task:
- to cover many languages of different language families
- to boost the development of MWE processing tools
- to make results of tools performing similar tasks comparable
- to take discontinuous MWEs into account
- to bring MWE detection closer to parsing
- to provide an multilingual open resource to the NLP community
- Seven systems particpated in the shared task (5 of them were multilingual). They submitted 71 results in total. Each of the 18 languages, for which annotated corpora were provided, was covered by at least 2 systems. The results are available on the official shared task page.

- The training and test corpora for the shared task have been released for 18 languages. In total, the corpus contains about 4.5 million tokens and about 55,000 VMWE annotations. See the official ST page for more details.
- Master spreadsheet for the corpus file management (pilot and final annotation)
- Current state of the annotations in FLAT (some languages are annotated outside FLAT)
- annotating training and evaluation corpora of about 3,500-4,000 MWEs per language (by combining pre-exiting data sets with newly annotated ones)
- annotation layers to decide (MWE layer, possibly also the part-of-speech layer)
- common annotation guidelines (but taking language specificities into account)
- selecting one or two text genres (e.g. newspaper texts)
- the corpus should be written in the original rather than translated
- the corpus should possibly be free from copyright issues, so as to be distributed under an open license
- annotation experts will be mostly from PARSEME
- teams participating in the contest may also be from outside the action
- Annotation guidelines v6 for the final annotation:
- Methodology for the final annotation phase:
- Guide for language leaders
- FLAT server
- FLAT user's and administration guide
- PARSEME-FLAT discussion group on Telegram for fast peer-to-peer feedback on FLAT annotation platform (usable on mobile phones and regular PCs via web browser, preferably Chromium or Google Chrome)
- Github space for reporting FLAT bugs (for authorised technical staff only)
- Gitlab space for discussing evaluation tools and annotation guidelines issues (for registered users only)
- Corpus for the final annotation:
- Corpus file directory
- Corpus format description
- parseme-tsv format for annotated files - files in this format are: (i) given on input to VMWE identification tools (in this case the last column contains underscores only), (ii) expected on output from VMWE identification tools (in this case the last column contains MWE tags or underscores)
- parseme-tsv-pos format - useful if (i) part-of-speech tags are available, to highlight verbs in FLAT; (ii) if VMWE pre-annotations are available
- parseme-tsv-split format - increasingly obsolete, used in the annotation of the platinum corpus v6; can still be used to upload (e.g. manually pre-annotated) files to FLAT.
- parseme-tsv-input format - obsolete; files in this format were initially supposed to be provided on input to VMWE identification tools; now the parseme-tsv format is used both on input and on output of such tools
- Corpus segmentation rules
- FLAT server - central on-line annotation platform used for the final annotation
- conllu2parsemetsv - a bash script for converting Universal Dependencies files in the CoNLL-U format into the parseme-tsv format
- conll2mwe - a Python script produced parseme-tsv files from CoNLL-U files with missing NoSpace information in the 10th column; the script (i) automatically guesses the value of the nsp (nospace), (ii) splitting of input file in a number of files (--NoF) with a specific number of sentence per files (--SpF), (iii) removes multi-word tokens (e.g., 3-4)
- folia2tsv - a Python converter from Folia (FLAT XML format) to parseme-tsv
- tsv2folia - a Python converted from parseme-tsv, parseme-tsv-pos, parseme-tsv-input, and parseme-tsv-split to Folia; it is also integrated, as a library, to FLAT so running it off-line is only needed for a specific use
- extract_annotated_mwes - a Python script extracting and sorting all annotated VMWEs from a file; can be used to check the annotation consistency
- Generic corpus tokenizer
Documents for pilot annotation (obsolete):
- annotation guidelines v4 and v5 used in pilot annotation phases 1 and 2
- annotation guidelines for quasi-universal categories:
- methodology for pilot annotation
- corpus format from the pilot annotation phase 2 and from the platinum v6 annotation
- UDPipe - trainable pipeline for tokenization, tagging, lemmatization and dependency parsing of CoNLL-U files. Trained models are provided for nearly all Universal Dependency treebanks. They can be used to POS-tag a corpus; the verbal POS tags can then be added to the files (see the 5th column of the parseme-tsv format) to be annotated for the shared task, which greatly speeds up the manual annotation. The output of UDPipe models is in the CoNLL format, which can be transformed to the parseme-tsv format by the conllu2parsemetsv.sh script.

We have received 20 expressions of interest so far from potential corpus contributors to the shared task. 21 languages are concerned and we divided them into 4 language groups. Group leaders coordinate the discussions on the annotation guidelines within their respective groups and communicate with the shared task leaders.
