Créer une usine à résumer des fichiers pdf en Python avec openai
Comme chacun le sait, Openai fournit des moteurs d'IA parmi les plus avancés du monde. Les capacités de ces IA sont nombreuses. Je trouve impressionnante la capacité de réaliser des résumés à partir de texte.
Ici j'ai fait un petit programme en python qui va chercher un fichier pdf à partir d'une url, qui stocke le fichier en local, qui lit le fichier et demande un résumé de chaque page.
Dans l'exemple, j'utilise le document
qui parle d'analyse financière (en anglais). Je vous laisse lire le document.

"Financial analysis involves the examination of both financial statements and financial
ratios to assess a firm's performance and make investment decisions. The common methods
of benchmarking include trend analysis and common-size statements. Financial ratios are
used to compare a company over time and with competitors; these include liquidity ratios,
leverage ratios, asset management ratios, profitability ratios, and market value ratios. The
Du Pont Analysis is also a valuable tool in understanding return on equity.
Profitability ratios measure a firm's effectiveness in turning sales or assets into profits. Market value ratios are used to gauge how attractive a firm's current price is relative to its earnings, growth rate, and book value. The DuPont analysis involves breaking down returns on equity into three components. Liquidity ratios show a company's short-term cash obligations and solvency ratios demonstrate the ability to meet debt obligations for extended periods of time. The most important ratio for
a banker considering a debt loan would be the times interest earned.
Asset management ratios are used to evaluate how management is using assets to generate profits. The P/E ratio is a measure of growth, with higher P/E ratios indicating growth firms. The DuPont identity analyzes return on equity. Comparing a company to others in different industries can show what areas the company and its industry are falling behind in.
The current ratio is a measure of a business's ability to meet its current liabilities with its current assets. It is calculated by dividing current assets by current liabilities. A higher current ratio is usually better, but may also indicate idle or underutilized resources in the company. The quick ratio is a stricter measure of
liquidity and is most useful when the proportion of illiquid current assets to total current assets is high. It is calculated by taking the sum of cash, marketable securities, and receivables, and then dividing it by current liabilities. Another approach involves subtracting all illiquid current assets from total current assets and
dividing the result by total current liabilities.
Quick ratio is useful for assessing liquidity in times of distress and is best used in relation to other ratios like the current ratio and cash ratio. The debt ratio
is used to measure a business's financial risk, and the times interest earned ratio determines a company's ability to pay off interest expenses with available earnings.
Debt ratio measures total debt exposure relative to total assets, and Times Interest Earned (TIE) ratio assesses if the company is earning enough to pay off the associated interest expense. Net Profit Margin measures the percentage of net income of the entity to net sales, and Return on Equity (ROE) ratio is a measure of profitability of stockholders' investments. Earnings per Share (EPS) is an indicator of the dollars of net income earned by the company per share of its common stock.
Earnings Per Share (EPS) and Price/Earnings (P/E) Ratio measure the value of a company's share price to its earnings. The Dividend Payout Ratio tells investors whether a company is reinvesting earned profits or distributing dividends. The Inventory Turnover Ratio tells if a business is efficiently managing its inventories.
Inventory Turnover Ratio measures how quickly a business is able to sell its inventory. Days' Sales Outstanding (DSO) Ratio measures the average number of days it takes for a business to collect its credit sales. Total Assets Turnover Ratio measures how successfully a company is utilizing its assets in generating revenue."
