Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

Disclosed is an indoor air quality control method using an intelligent air purifier. The indoor air quality control method according to an embodiment of the present invention may determine, when receiving indoor dust concentration data of the room in which an air purifier is located from the air purifier, whether indoor ventilation is necessary by predicting progress of indoor dust concentration on the basis of an output value of a learning model having the received dust concentration data as an input value and comparing the predicted progress with external dust concentration data received from a server of the Meteorological Administration. Accordingly, it is possible to predict changes in indoor dust concentration and recommend an appropriate ventilation time point. The intelligent air purifier and the indoor air quality control method using same of the present invention may be associated with an artificial intelligence module, a device related to 5G services, etc.
