Algal biomass refers to the biological material obtained by cultivating microalgae or seaweeds

 Algal biomass refers to the biological material obtained by cultivating microalgae or seaweeds, which can provide lipids, carbohydrates, and proteins as raw materials for biofuels, fertilizers, feed, and chemicals. Compared to terrestrial plants, algae grow faster, can be produced in non-arable land or aquatic areas, and absorb CO₂, making them promising sustainable resources. Advantages include high productivity, avoidance of land competition, and versatility, while challenges remain: high costs, difficulties in scaling up, large water and nutrient demands, energy-intensive drying, and insufficient yields, so commercial applications are still limited.

In practice, the most workable approach is to measure a composite “civility score” built from multiple indicators.

  1) Model-based indicators (machine learning) Toxicity/Aggression: Use Jigsaw’s Perspective API to obtain probabilities for “TOXICITY,” “INSULT,” “PROFANITY,” “IDENTITY_ATTACK,” etc. Japanese is supported (see the official language table). Politeness: Stanford’s research established a framework for estimating “politeness” from markers like request forms, hedges, honorifics, etc. It’s English-centric, but the methodology can be adapted to Japanese. The R package politeness is also useful. 2) Lightweight rules for Japanese (highly interpretable) Honorific/hedge rate: Ratios of “です/ます,” “〜でしょうか,” “お手数ですが,” “お願いします,” and the like. Presence of slurs/derogatory terms: A custom NG-word list (including figurative or euphemistic forms). Imperatives/strong assertions: Frequency of “〜しろ,” “〜に決まってる,” heavy use of exclamation marks, ALL-KATAKANA bursts, etc. Consideration/evidence markers: Signs of dialogic and verifiable style such as “根拠：,” “出典：,” “もし〜なら.” 3) ...
