LELIE - LELIO
LELIE is your personal intelligent assistant that helps you improve your technical documents. The main characteristics of LELIE are:
- PRESCRIPTIVE: dynamic modelling of the main principles and norms of technical authoring, over several industrial domains,
- ADAPTABLE and RELIABLE: auto-adaptative approach based on an accurate analysis of technical writing,
- SIMPLE and INTUITIVE: available as a Plug-In for Word and Excel,
- RELEVANT and EFFICIENT: LELIO automatically customises LELIE to your industrial domain and authoring habits,
LELIE is FREE: open source, languages: French and English. We celebrate 100 free copies distributed!

LELIE: an intelligent technical text clinic
The functions offered by LELIE are based on existing norms and the everyday practice of technical authors. LELIE also offers specific controls dedicated to precise types of documents: specifications, requirements, procedures, equipment notices, etc. and to specific theoretical approaches (e.g. pattern-based authoring, minimalist technical writing).
The 10 major functions are the following:
(1) Fuzzy and vague terms detection: since these affect the understandability and the verifiability of instructions or requirements.
(2) Terms to avoid detection: such as very generic terms, buzz terms, ambiguous terms, or common terms not in the technical domain ontology.
(3) Sentence complexity analysis: LELIE detects via a metrics those sentences which are difficult to read because of their complex structure (with e.g. long coordinations, embedded relatives), their length, or the presence of too many technical terms.
(4) Ambiguous pronoun reference detection: LELIE detects these pronouns in different configurations since they frequentlty introduce ambiguities.
(5) Various types of negation detection: a number of negative forms should be avoided: they introduce completeness and verifiability problems.
(6) Tenses to avoid detection: in particular agentless passives, future tenses and conditional and subjunctives must be avoided as much as possible since they affect the completeness of the document.
(7) Controls on the syntactic patterns imposed by the document style: the objective is to ensure that sentences follow the schemas or patterns required by the domain or company.
(8) Enumeration regularity controls: enumerations and cells in charts are easier to understand if they follow a regular syntactic format.
(9) Cohesion controls: LELIE controls the terminological regularity of documents, given a domain ontology. This avoids term proliferations.
(10) Similarities analysis: LELIE identifies in a text, even a large text, those elements which are very similar: this may indicate redundancies or possible incoherences.
Via Plug-Ins in Word and Excel, annotations are produced as Word comments. These comments include several features including the severity level of the error. Comments can be customized to the user habits.
LELIO or the art of customisation
LELIE is a generic kernel: it works rather well on any type of technical text.
For better results, in error diagnosis and corrections to make, LELIO is a research action that allows you to create your own LELIE, customized to your domain and authoring practices. These elements are specified via a collaborative environment.
To realize this customization, LELIO requires:
- samples of your texts,
- your authoring guidelines or habits or preferences, specified in a given format,
- your preferences in terms of disgnosis display.
Contact us to use LELIO, developed by an independent group (Lelie Consulting Network).
Perspectives - Road-Map
Our perspectives are organized around major topics in technical writing. A close collaboration with technical writers allows us to identifiy the following topics:
- writing documents in English when English is not your mother tongue: typical errors and remediation strategies, IREB project,
- the characterization of inocuity: the difficulty to establish error diagnosis which are relevant: indeed many so called errors are perfectly understandable, in spite of norms which are too strict and general,
- the analysis of forms of incoherence among requirements or in technical documents,
- the developpement of an auto-adaptative system to correct errors,
- social and cognitive ergonomics in LELIE.

TextCoop and LELIE are good quality research prototypes, which are used in real industrial contexts. They are distributed FREE of charge (see section juridique).
The TextCoop and LELIE archives contain a user manual to start the system, running examples are provided.
discourse semantics analysis platform, SOFTWARE freely available (French and English), OPEN SOURCE.
TEXTCOOP V5.1 (September 2015, archive with the TextCoop engine, and large samples of updates discourse analysis rules and related lexical data). TEXTCOOP V5.1,
TextCoop has been distributed to more than 35 research centers or companies.
LELIE V1: old version (2014), runs well but based on a simple pattern technology, with some linguistic and technical limitations.
CODE: LELIE V1 French and LELIE V1 English.
LELIE V2: version based on constraints and rules, much more efficient and accurate. Associated with LELIO for customization, compatible with RAT-RQA.
Last version: LELIE V2.2 (May 2016), about 100 copies sent at the moment.
Please send email to firstname.lastname@example.org or to email@example.com to get LELIE V2.2 in the Word/Excel Plug-In, CC BY NC, see the juridical corner section.
A version LELIE V3 is under preparation: it places the user at the very center of the process of the technical text improvement.

LELIO V1 is not distributed. For any customisation of LELIE by LELIO, contact firstname.lastname@example.org
The juridical corner
TextCoop, LELIE and LELIO prototypes are results of research projects developed by the CNRS, the ANR and the University in collaboration with the CNAM and EDF. They belong to the CNRS and the university.
Authors are happy to share these results and associated prototypes and data provided that some return of experience, positive or negative is sent back to us, the goal being to help us further improve these prototypes.
- TextCoop V4 and V5 are under CC BY license (open-source, commercial applications allowed) since August 2015.
- LELIE V1 and V2.2 are under license CC BY NC (free usage for research, commercial or technical opportunity analysis, internal tests).
The plugs-Ins Word and Excel are Open Source.
- To make a commercial use of LELIE V2.2, there are several simple solutions, contact: email@example.com
LELIE has been tested or is being tested in several companies in various industrial sectors: EDF, SNCF, IBM, Reuters (financier), Orange, Siemens, Accenture, LGM, Pôle Emploi, Daimler-Benz, IFDS, RequirementOne, INCOSE, the ReuseCompany, etc.
LELIE is used for teaching purposes for technical text authoring, in particular requirements, in cooperation with the IREB.
LELIE is being integrated in various environments (Quality Center).
Products based on LELIE with our collaboration: Semiosis.zeen (Lelie V2.1 redone, plug-In low cost), LM (Lelie V2.1 for multilingual documents), Inuite.de. More ambitious systems in preparation.
