Il successo della Lega, i media e le “crisi” migratorie

La crescita di Salvini e della Lega è forse per la politica italiana l’evento più significativo del 2018. Nel gennaio 2018, prima delle elezioni di marzo, la Lega di Salvini era intorno al 12-13%.

Explicit semantic analysis with R

Explicit semantic analysis (ESA) was proposed by Gabrilovich and Markovitch (2007) to compute a document position in a high-dimensional concept space. At the core, the technique compares the terms of the input document with the terms of documents describing the concepts estimating the relatedness of the document to each concept. In spatial terms if I know the relative distance of the input document from meaningful concepts (e.g. ‘car’, ‘Leonardo da Vinci’, ‘poverty’, ‘electricity’), I can infer the meaning of the document relatively to explicitly defined concepts because of the document’s position in the concept space.

  • Get Miles: using treemap to visualise running distances
    By 30th September 2022, I had clocked up a total of over 2000 km of running in 2022. This milestone was a good opportunity to look at how I got to this point. The code is shown below. First, we can make a histogram to look at the distance of runs. From this ... Continue […]

  • Not frequentist enough.
    I think that many mistakes in applied statistics could be avoided if people were to think in a more frequentist way. Look at it this way: In the usual way of thinking, you apply a statistical procedure to the data, … Continue reading →
