Prototype of text search with optional grammatical type

Inconditional search

Let us expand the idea of text analysis derived from rule-based translation. Above is an example of a classic word-based search. In this particular case, it is the French word ‘été’. This word is ambiguous because it can be a common noun (‘summer’), or a past participle (‘been’). Below is an example of a search for the word ‘summer’ associated with the grammatical type ‘common noun’.

Conditional search based on ‘noun’ grammatical type

Finally, we have below an example of a search for the word ‘summer’ associated with the grammatical type ‘past participle’.

Conditional search based on ‘past participle’ grammatical type

Why it’s worth it to engage in rule-based translation

Rule-based translation is difficult to implement. The main difficulty encountered is taking into account the groups of words, so as to be on a par with statistics-based translation. The main problems in this regard are (i) polymorphic disambiguation; and (ii) building a fair typology of grammatical types. But once these steps begin to be mastered, there are many advantages. What seems essential here is that with the same piece of software, both machine translation and text analysis can be carried out. Among the modules that are easy to implement are the following:

  • lemmatizer
  • part-of-speech tagger
  • singularizer
  • pluralizer
  • grammar checker
  • type extractor: a module that allows you to extract words from a text according to their grammatical category

For the implementation of rule-based translation provides the machine with some inherent understanding of the text, in the same way that a human being does. To put it in a nutshell, it is better artificial intelligence.

Finally, other modules, more advanced, seem possible (to be confirmed).

For a Typology of Auditory Verbal Hallucinations Based on their Content

A paper published in Activitas nervosa Superior (2020), 62, pages 104–109.

Auditory verbal hallucinations (AVHs) are a common symptom of schizophrenia. Studies have focused on a classification of AVHs, based on different criteria. Subtypes of AVHs have been defined, distinguishing according to whether they are internal/external, single/multiple, unimodal/multimodal, benevolent/malevolent, permanent/intermittent, etc. The purpose of this study is to propose a classification of AVHs based on their content. We first identify the subtype that is directly associated with the polythematic delusions inherent in schizophrenia. Second, we distinguish subtypes related to other comorbid psychiatric disorders associated with schizophrenia in the patient: generalized anxiety disorder, depression, body dysmorphic disorder, etc. Finally, we suggest that such a differentiation could allow a correlative adaptation of the corresponding cognitive-behaviour therapy.
