Submission deadline: May 13, 2019
Workshop date: IJCAI-19 August 10-16 2019, Macao, China

Sentences are basic units of the written language and detecting the beginning and end of sentences, or sentence boundary detection (SBD) is a foundational first step in many Natural Language Processing (NLP) applications, such as POS tagging; syntactic, semantic, and discourse parsing; information extraction; or machine translation.

Despite its important role in NLP, sentence boundary detection has so far not received enough attention. Previous research in the area has been confined to formal texts only (news, European Parliament proceedings, etc.) where existing rule-based and machine learning approaches are extremely accurate (when the data is perfectly clean). No sentence boundary detection research to date has addressed the problem in noisy texts extracted automatically from machine-readable formats (generally PDF file format) files such as financial documents.

In this shared task, we focus on extracting well-segmented sentences from Financial prospectuses by detecting their beginning and ending boundaries. These are official PDF documents in which investment funds precisely describe their characteristics and investment modalities. The most important step of extracting any information from these files is to parse them to get a noisy unstructured text, clean it, format information (by adding several tags) and finally, transform it into semi-structured text, where sentence boundaries are well marked.

Task Design

As part of the FinNLP, we present a shared task on sentence boundary detection in noisy text extracted from financial prospectuses, in two languages: English and French.

Systems participating in this shared task will be given a set of textual documents extracted from pdf files, which are to be automatically segmented to extract a set of well-delimited sentences (clean sentences).

Participants can choose to work on both languages, or submit systems for one language only.

In addition to the textual version of the documents, we will provide their PDF original files. Recommendations of additional language resources will also be listed/provided for some languages by the organizers.

Data Format:

In the provided dataset, participants will get a json format containing "text", that corresponds to the text to be segmented, begin_sentence and end_sentence correspond to all indexes of tokens marking the beginning and the end of well-formed sentences in the text. Notice that the provided text was already word tokenized using NLTK, participants should keep this tokenization as it is since all tokens indexes are instantiated based on it. The first token in the text will have then the index 0.


'text': " UFF Sélection Alpha AINFORMATIONS CLÉS POUR L' INVESTISSEUR « Ce document fournit des informations essentielles aux investisseurs de cet OPCVM . Il ne s'agit pas d' un document promotionnel . Les informations qu ' il contient vous sont fournies conformément à une obligation l égale , afin de vous aider à comprendre en quoi consiste un investissement dans ce fonds et quels risques y sont associés . ..." ,

'begin_sentence': [8, 21, 31 , ...],

'end_sentence': [20, 30, 66, ...]


All of the input text will be preprocessed in a common way to make sure all participants have access to all of these features at no additional overhead novelty cost. Rule-based, machine learning, deep learning, or hybrid techniques are all allowed.

Participants will get annotated training/dev data, and further a blind test data as a json format but with just the text. They should then predict the lists begin_sentence and end_sentence and submit the result in the same json format as of the training data.
