Please introduce yourself and your main missions
I work within the Natural Language Processing (NLP) Group, attached to the Strategy & Innovation department, in charge of all subjects related to research, Innovation and NLP. We are a multi-energy group present in 130 countries, with 100,000 employees. We operate throughout the energy chain, from production to processing. There are multitudes of energies: Traditional energies like oil and gas and more recent ones like wind power, solar power and renewable energies. Our main mission is to lead the networks of our department. It is a set of technical business networks common to all branches of the Group.
Why did you set up a NLP semantic analysis solution for the company?
We have two main objectives on our department side:
- Respond to Knowledge Management issues
- Provide the means to test and implement new technologies (innovation) and to share and develop the skills necessary for the Group’s needs.
In order to alleviate our KM challenges, we have set up a thesaurus; NLP allows it to be enriched and, by combining it with our tools, thus facilitates access to knowledge. This also improves the quality of our search engine and the relevance of the words searched and allows more efficient navigation between all the documents made available. Concerning the project: it is financed and managed by our department. It consists of analyzing the breakdown reports of the equipment in certain industrial sites in order to derive maximum value from them. The objective of the project is to respond to safety issues particularly in the Chemical Refining branch. This involves analyzing the reports written by operators working on equipment related to instrumentation (equipment with safety functions). This guarantees the safety of our facilities. The whole point is to use NLP to analyze all these unstructured mini-reports, to check if the equipment is working properly. This is a very important piece of information. Previously the analysis was done manually on a very small sample of data.
Today, with Proxem Studio, we have analyzed nearly 400,000 logs linked to breakdowns or maintenance reports. As you can see, the semantic analysis solution implemented allows us to enrich the vocabulary, to combine it with our research tools and thus to contribute to the improvement of our results. In addition, we want this vocabulary to be accessible to the whole company which works on NLP use cases. Internally, we try to promote these uses, namely the use of semantic resources, so that it can be reused in as many different contexts as possible. Today, we will publish this vocabulary in another tool, so that
data scientists can complete the vocabulary to build their own thesauruses.
Why did you choose Proxem Studio for your projects?
The “Vocabulary Thesaurus” project took place more than two years ago after a manual construction of this thesaurus. We had not seen many other solutions suitable for this use. The major advantage of the tool is that it does not require a very technical background, so the teams, in particular our part-time librarian, were able to use it quickly after a short training. The semantic analysis solution implemented allows us to enrich the vocabulary, to combine it with our research tools and thus to contribute to the improvement of our results.
What are the results of our solutions?
We had 400 keywords in the existing thesaurus. Today with Proxem Studio, we have nearly 6,000 concepts, which is quite consistent. This plays an important role for our search engine to improve all that is the relevance of the search results. Vocabulary had an impact, but there were also other related developments to improve relevancy. The main objective of the project is not the ROI but the safety of our installations. Thanks to all these results, we were able to calculate the failure rates of our equipment. We have consistent results compared to what has been evaluated in the past. These good results allow us to validate this method in an official way and thus we hope to be able to automate it and especially to deepen its use in order to provide even more details.

What are the perspectives for development?
Regarding the project, we realize that this use case will meet essential security objectives; but we can also apply it to address other issues. We are in the value search phase concerning:
- Taking all the information on breakdowns to have more visibility on maintenance costs.
- Setting up action plans to check the quality of the equipment and make it more available to extend it to other industrial sites.
- Comparing sites and highlighting best practices from site to site, and looking at the subcategories of equipment and suppliers, which are better or worse
- than the others.
- Reviewing the equipment purchasing strategy; we want to estimate the maintenance costs.
When we have to assess the quality of an industrial asset, we realize that what we have put in place within the framework is interesting.
Evaluating the quality and safety of our equipment on a large scale is the goal.
